NOISE AND EMISSIONS REQUIREMENTS

NOTE

This truck may be equipped with specific emissions control components/systems* in order to meet applicable Federal and California noise and exhaust emissions requirements. Tampering with these emissions control components/systems* is against the rules that are established by the U.S Code of Federal Regulations, Environment Canada Regulations and California Air Resources Board (CARB). These emissions control components/systems* may only be replaced with original equipment parts. Additionally, most vehicles in North America will be equipped with a Greenhouse Gas (GHG) Vehicle Emission Control Information door label indicating its certified configuration. The vehicle components listed on this label are considered emission control devices.

Modifying (i.e. altering, substituting, relocating) any of the emissions control components/systems defined above will affect the noise and emissions performance/certification. Modifications that alter the overall shape and aerodynamic performance of a tractor will also affect the emission certification. If modifications are required, they must first be approved by the manufacturer. Unapproved modifications could negatively affect emissions performance/certification. There is no guarantee that proposed modifications will be approved.

Tires may be substituted provided the new tires possess a Coefficient of rolling resistance (Crr) equal to or lower than Crr of the original tires. Consult with your tire supplier(s) for appropriate replacement tires.

Contact the engine manufacturer for any requirements and restrictions prior to any modifications.

For Cummins Contact 1-800-DIESELS or your local Cummins distributor. Reference AEB 21.102.

It is possible to relocate the DEF tank, however the relocation requirements need to be followed. Any variance from the relocation requirements may cause the emissions control components/systems to operate improperly potentially resulting in engine de-rate.

2 SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-4

NOTE All 2017 engine emissions certified vehicles will be equipped with an On-Board

Diagnostics (OBD) system. The OBD system is designed to detect malfunctions of any engine or vehicle component that may increase exhaust emissions or interfere with the proper performance of the OBD system itself.

All diesel engines will be equipped with an On-Board Diagnostics (OBD) system. The OBD system consists of computer program on one or more of the vehicles Electronic Control Units (ECUs). This program uses information from the control system and from additional sensors to detect malfunctions. When a malfunction is detected, information is stored in the ECU(s) for diagnostic purposes. A Malfunction Indicator Light (MIL) is illuminated in the dash to alert the driver of the need for service of an emission-related component or system.

To ensure compliance to emissions regulations, the final configuration of certain features of the completed vehicle must meet specific requirements. This section describes requirements relevant for only the most common or critical modifications done by body builders. For a complete description of acceptable modifications, see the application guidance available from the manufacturer of the engine installed in the chassis.

FUEL SYSTEM The following are highlights of some of the more common or critical aspects of this system.

The overall system restriction may not exceed the restriction limitations set forth by the engine manufacturer for both supply and return.

Ensure that fuel lines are not pinched or can potentially be damaged when installed between body and frame

Fuel lines must be routed and secured without dips or sags

There must be easy access to filter(s) and fill cap

The tank vent may not obstructed

Added accessories (heaters, generators) cannot introduce air into system

Fuel tank must be located so that the full level is not above cylinder head

Ultra-Low Sulfur Fuel Only labels must be present on the dash and fuel fill

Modification of the pressure side secondary filter and plumbing is not allowed without engine manufacturer approval

Body installation of fuel tank or routing of lines must not cause significant increase in fuel temperature

Fuel hoses shall meet or exceed OEM supplied hose material construction specifications

Formed nylon fuel lines with quick-connects are installed underneath the cab and hood along the frame rail. Behind the cab from the fuel tee to tanks are wirebraid-reinforced rubber lines. Supply and return fittings are poka-yoked to prevent incorrect assembly.

COMPRESSED AIR SYSTEM The following are highlights of some of the more common or critical aspects of this system.

Air system modification must meet applicable FMVSS regulations

Compressed Air tank may not be modified (exception addition or removal of fittings or relocation of the tank)

Added devices or bodywork may not interfere with or rub air lines

Air supply to the engine doser may not be restricted or disconnected

Air lines should be routed, protected from heat, and properly secured to prevent damage from other components

Care should be taken so that air lines do not rub against other components

Care should be taken to protect the air system from heat sources. EXHAUST AND EXHAUST AFTER-TREATMENT SYSTEM The following are highlights of some of the more common or critical aspects of this system.

The following after-treatment and exhaust system components may not be modified: DPF assembly SCR Catalyst assembly

Exhaust pipes between the engine and after-treatment devices (DPF, SCR Catalyst) and between after-treatment devices NOx Sensors PM Sensor

The following modifications may only be done within the guidelines of the DEF System Relocation Guide.

Modifications to Diesel Exhaust Fluid (DEF) throttle, suction, or pressure lines Modification or relocation of the DEF tank Modification of coolant lines to and from the DEF tank

All DEF and coolant lines should be routed, protected, and properly secured to prevent damage during vehicle operation or other components

2 SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-6

If relocation of the DCU or ACM is necessary, use existing frame brackets and mount inside of frame flanges where necessary. Do not extend the harnesses

The DPF, the SCR catalyst, or their mounting may not be modified

The NOx sensor may not be relocated or altered in any way; this includes re-clocking the after- treatment canister or reorienting the sensor(s)

Exhaust pipes used for tailpipes/stacks must be properly sized, and must prevent water from entering

Ensure adequate clearance between the exhaust and body panels, hoses, and wire harnesses

The body in the vicinity of the DPF must be able to withstand temperatures up to 400C (750F)

Do not add thermal insulation to the external surface of the DPF

The SCR water drain hole may not be blocked

Allow adequate clearance (25mm (1 inch)) for servicing the DPF sensors, wiring, and clamped joints

Drainage may not come in contact with the DPF, SCR catalyst, sensors or wiring

Allow sufficient clearance for removing sensors from DPF. Thermistors require four inches. Other sensors require one inch

Wiring should be routed, protected from heat, and properly secured to prevent damage from other components

The exhaust system from an auxiliary power unit (APU) must not be connected to any part of the vehicle after-treatment system or vehicle tail pipe.

COOLING SYSTEM The following are highlights of some of the more common or critical aspects of this system.

Modifications to the design or locations of fill or vent lines, heater or defroster core, and surge tank are not recommended

Additional accessories plumbed into the engine cooling system are not permitted, at the risk of voiding vehicle warranty

Coolant level sensor tampering will void warranty

When installing auxiliary equipment in front of the vehicle, or additional heat exchangers, ensure that adequate air flow is available to the vehicle cooling system. Refer to engine manufacturer application guide- lines for further detail

When installing FEPTO drivelines, the lower radiator anti-recirculation seal must be retained with FEPTO driveline clearance modification only

Changes made to cooling fan circuit and controls are not allowed, with the exception of AC minimum fan on time parameter

See owners manual for appropriate winter front usage

2 SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-7

ELECTRICAL SYSTEM The following are highlights of some of the more common or critical aspects of this system.

Electrical harnesses providing battery power and electronic control signals to engine and emissions control/ vehicle OBD components including datalinks may not be spliced. These emissions control/vehicle OBD components include the following:

throttle pedal vehicle speed sensor after-treatment wiring 9-pin OBD Connector CAN Communication / OBD Diagnostic wiring

If the alternator or battery is substituted, it must meet the requirements of the engine manufactures guide- lines. This includes alternator ground voltage drop and alternator ground cable effectiveness. See the engine manufactures guidelines for recommended test procedure. Additionally the maximum voltage differential and the peak-peak voltage differential between the engine ECM block ground stud and battery negative terminal may not exceed 500 mV under any combination of loads or operating conditions.

Only an OBD compliant battery disconnect switch may be installed on vehicles equipped EPA 2013 and beyond compliant diesel engines. An OBD compliant switch and harness, even in the off position, supply a small amount of power to the engine controller and enable certain emissions critical functions (e.g. DEF line purge). Any modifications to the electrical system which interrupt this power supply will cause OBD fault codes and illumination of the MIL. In addition, such a modification will render the engine non-compliant with certain emission regulations. As a general rule of thumb, you can remove and replace a battery disconnect switch on a truck equipped with a battery disconnect switch at the factory. However, if a battery disconnect switch was not installed in the factory a significant harness modification is required before a battery disconnect switch can be added.

Installation of aftermarket transfer-cases must address the vehicle speed sensor position. The standard position of the speed sensor is at the transmission tail shaft. When a transfer-case is added it is best to relocate the sensor to the axle side output shaft of the transfer-case. This is typically accomplished by adding a tone wheel into the driveline yoke assembly.

Wiring extensions for the after-treatment wiring are available for relocating the DEF tank from your dealer via Paccar Parts. For relocation of DEF tank, refer to the after-treatment section of this manual.

The emission system requires an accurate Outside Air Temperature (OAT) reading in order to properly run its control algorithms. The OAT sensor is located in the drivers side mirror assembly on Peterbilt trucks and is shown in the figures below. If the body builder needs to modify the mirror assembly in any way, it is important the OAT sensor stay positioned on the mirror assembly. Running the vehicle without the OAT sensor connected will cause the MIL lamp to illuminate. If needed, a replacement sensor can be ordered from your Peterbilt dealer.

2 SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-8

FIGURE 2-3: Aerodynamic Mirror OAT Sensor Location

Coolant Sensor considerations are given in the Cooling section above

The OBD/Diagnostic connector port is located below the dash to the left of the steering wheel. This connector and its location may not be changed.

All vehicles equipped with EPA 2013 compliant diesel and bi-fueled engines must be equipped with a Malfunction Indicator Lamp (MIL) lamp. This lamp is required to be an engine outline symbol as defined by ISO (International Standards Organization). The figure below shows the instrument cluster and MIL lamp position. Note this lamp location is fixed with respect to the controls and its location may not be changed if you are updating the warning lamp cards.

FIGURE 2-4: Instrument Cluster for 579/567 used with EPA 2013 Emission compliant engines. The Check Engine lamp and/or the MIL will appear in the Driver Information Display. See 579/567 Operators Manual for more information.

In addition to the sensors and lamps above, the emission system also depends on signals from the exhaust DPF (Diesel Particulate Filter), SCR (Selective Catalytic Reduction), and NOx sensor. Wiring between these devices, the Dosing Control Unit (DCU) and engine ECM should not be tampered with or altered in any way.

2 SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-9

AIR INTAKE SYSTEM The following are highlights of some of the more common or critical aspects of this system.

The air intake screen may not be blocked, either fully or partially

Modification to the air intake system may not restrict airflow. For example, pipe diameter may not be reduced

All sensors must be retained in existing locations

To retain system seal, proper clamp torque must be used. Refer to service manual for proper clamp torque

CHARGE AIR COOLER SYSTEM The following are highlights of some of the more common or critical aspects of this system.

The Charge Air Cooler may not be modified

The installation of engine over-speed shutdown devices must not introduce restriction in the intake system

All plumbing associated with the charge air cooler may not be modified

REAR SUSPENSION LAYOUTS The rear suspension layouts are provided as a tool to help layout bodies prior to arrival. The applicable dimensions are shown. Be sure to check the axle spacing that is shown, as alternate spacing may exist and could change some of the dimensions. The dimensions shown are the most typical installations, in special cases some hole locations will move. If you are planning on using the holes shown for your body installation, please confirm with your local Peterbilt dealer that the drawing below will be the installation used on your specific truck. Ensure that proper torque is used to reinstall any suspension components. It would be a good idea in this case to order the frame layout of your chassis along with your truck order. This can be done on any Peterbilt truck, and will be provided ahead of the build schedule. If there are hole locations that are not detailed please work with your local Peterbilt Dealer to request that information. Additionally optional axle spacing are shown in the charts, if you would like details on the frame drilling with optional spacing, please contact your local Peterbilt dealer. NOTE: Actual axle spacing can depart from nominal due to axle slant requirements. Final axle spacing can vary by more than an inch from nominal in some cases. If precise axle spacing is critical due to body installation or state/local regulatory requirements please contact Peterbilt Applications/Technical Support for assistance.

LIFT AXLES (PUSHERS AND TAGS) The rear pusher axle layouts are provided as a tool to help layout bodies prior to arrival. The applicable dimensions are shown. When using the pusher layouts to determine available frame space please be aware that clearances required are not shown. For information that may not be detailed in these drawings work with your local Peterbilt Dealer to request that information.

Peterbilt will automatically install highest lift axle kit as applicable based on chassis frame height and loading conditions. Lift axle available run range it utilized, along with frame height and lift axle tire size to identify applicable kits that can be installed. Installing highest lift axle kit will maximize ground clearance when axle is in lifted state. If needed, kit may be lowered in order to clear driveline when in lifted state.

FRAME SPACE REQUIREMENTS

This section includes drawings and charts related to frame space components to ensure adequate space for fuel tanks, ladder steps, additional tool/battery boxes, pusher axles and other frame mounted components, the amount of available space must be calculated by using the formula below.

BASIC FORMULA: BOC Frame Space = Wheelbase - Dimension A - Dimension C - Dimension B

Dimension "A" (shown in charts on following pages) is the minimum clearance measured from the centerline of the front axle to the back of the under cab component (DPF/SCR exhaust, fuel tank, battery box, tool box, etc). Dimension "C" is the amount of space from the rear of the under cab component to the back of the DEF tank (can be on LH or RH rail). Dimension "B" is the amount of required suspension and quarter fender clearance from the rear axle centerline to clear rail for a given suspension.

4 BODY MOUNTING

Peterbilt Motors Company 4-2

CRITICAL CLEARANCES REAR TIRES AND CAB

CAUTION: Insufficient clearance between rear tires and body structure could cause damage to the body during suspension movement.

Normal suspension movement could cause contact between the tires and the body. To prevent this, mount the body so that the minimum clearance between the top of the tire and the bottom of the body is 8 inches (203 mm). This should be measured with the body empty. See FIGURE 4-1.

FIGURE 4-1. Minimum Clearance Between Top of Rear Tires and Body Structure Overhang

CAUTION: Maintain adequate clearance between back of cab and the front (leading edge) of mounted body. It is recommended the body leading edge be mounted 4 in. behind the cab. See FIGURE 4-2.

NOTE: Be sure to provide maintenance access to the battery box and fuel tank fill neck.

FIGURE 4-2. Minimum Back of Cab Clearance

4 BODY MOUNTING

Peterbilt Motors Company 4-3

BODY MOUNTING USING BRACKETS

CAUTION: Always install a spacer between the body subframe and the top flange of the frame rail. Installation of a spacer between the body subframe and the top flange of the frame rail will help prevent premature wear of the components due to chafing or corrosion.

WARNING! When mounting a body to the chassis, DO NOT drill holes in the upper or lower flange of the frame rail. If the frame rail flanges are modified or damaged, the rail could fail prematurely and cause an accident. Mount the body using body mounting brackets or Ubolts.

FRAME SILL If the body is mounted to the frame with brackets, we recommend a frame sill spacer made from a strip of rubber or plastic (delrin or nylon). These materials will not undergo large dimensional changes during periods of high or low humidity. The strip will be less likely to fall out during extreme relative motion between body and chassis. See FIGURE 4-3.

FIGURE 4-3. Spacer Between Frame Sill and Body Rail Rubber or Plastic

4 BODY MOUNTING

Peterbilt Motors Company 4-4

BRACKETS

When mounting a body to the chassis with brackets, we recommend designs that offer limited relative movement, bolted securely but not too rigid. Brackets should allow for slight movement between the body and the chassis. For instance, FIGURE 4-4 shows a high compression spring between the bolt and the bracket and FIGURE 4-5 shows a rubber spacer between the brackets. These designs will allow relative movement between the body and the chassis during extreme frame racking situations. Mountings that are too rigid could cause damage to the body. This is particularly true with tanker installations.

FIGURE 4-4. Mounting Brackets FIGURE 4-5. Mounting Brackets

4 BODY MOUNTING

MOUNTING HOLES

When installing brackets on the frame rails, the mounting holes in the chassis frame bracket and frame rail must comply with the general spacing and location guidelines illustrated in FIGURE 4-6.

FRAME DRILLING

WARNING! When mounting a body to the chassis, DO NOT drill holes in the upper or lower flange of the frame rail. If the frame rail flanges are modified or damaged, the rail could fail prematurely and cause an accident. Mount the body using body mounting brackets or Ubolts.

FIGURE 4-8. Frame Rail Flange Drilling Prohibited

WARNING! DO NOT drill closely spaced holes in the frame rail. Hole centers of two adjacent holes should be spaced no less than twice the diameter of the largest hole. Closer spacing could induce a failure between the two holes.

CAUTION: An appropriately sized bolt and nut must be installed and torqued properly in all unused frame holes. Failure to do so could result in a frame crack initiation around the hole.

CAUTION: Use care when drilling the frame web so the wires and air lines routed inside the rail are not damaged. Failure to do so could cause an inoperable electrical or air system circuit.

CAUTION: Never use a torch to make holes in the rail. Use the appropriate diameter drill bit. Heat from a torch will affect the material properties of the frame rail and could result in frame rail cracks.

CAUTION: The hole diameter should not exceed the bolt diameter by more than .060 inches (1.5mm).

4 BODY MOUNTING

Peterbilt Motors Company 4-7

BODY MOUNTING USING UBOLTS If the body is mounted to the frame with Ubolts, use a hardwood sill (minimum 1/2 inch (12.7 mm) thick) between the frame rail and body frame to protect the top surface of the rail flange.

WARNING! Do not allow the frame rails or flanges to deform when tightening the Ubolts. It will weaken the frame and could cause an accident. Use suitable spacers made of steel or hardwood on the inside of the frame rail to prevent collapse of the frame flanges.

Use a hardwood spacer between the bottom flange and the Ubolt to prevent the Ubolt from notching the frame flange. See FIGURE 4-9.

FIGURE 4-9. Acceptable U-Bolt Mounting with Wood and Fabricated Spacers

WARNING! Do not allow spacers and other body mounting parts to interfere with brake lines, fuel lines, or wiring harnesses routed inside the frame rail. Crimped or damaged brake lines, fuel lines, or wiring could result in loss of braking, fuel leaks, electrical overload or a fire. Carefully inspect the installation to ensure adequate

clearances for air brake lines, fuel lines, and wiring. See FIGURE 4-10.

FIGURE 4-10. Clearance Space for Air Lines and Cables

WARNING! Do not notch frame rail flanges to force a Ubolt fit. Notched or damaged frame flanges could result in premature frame failure. Use a larger size U-bolt.

CAUTION: Mount Ubolts so they do not chafe on frame rail, air or electric lines.

4 BODY MOUNTING

Peterbilt Motors Company 4-9

REAR BODY MOUNT When Ubolts are used to mount a body we recommend that the last body attachment be made with a fishplate bracket. See FIGURE 4-11. This provides a firm attaching point and helps prevent any relative fore or aft movement between the body and frame. For hole location guidelines, See FIGURE 4-7.

SECTION 5 FRAME MODIFICATIONS INTRODUCTION Peterbilt offers customer specified wheelbases and frame overhangs. So, in most cases frame modifications should not be necessary. However, some body installations may require slight modifications, while other installations will require extensive modifications. Sometimes an existing dealer stock chassis may need to have the wheelbase changed to better fit a customers application. The modifications may be as simple as modifying the frame cutoff, or as complex as modifying the wheelbase. DRILLING RAILS If frame holes need to be drilled in the rail, see SECTION 4 BODY MOUNTING for more information. MODIFYING FRAME LENGTH The frame overhang after the rear axle can be shortened to match a particular body length. Using a torch is acceptable; however, heat from a torch will affect the material characteristics of the frame rail. The affected material will normally be confined to within 1 to 2 inches (25 to 50mm) of the flame cut and may not adversely affect the strength of the chassis or body installation. CHANGING WHEELBASE Changing a chassis wheelbase is not recommended. Occasionally, however, a chassis wheelbase will need to be shortened or lengthened. Before this is done there are a few guidelines that should to be considered.

WARNING! When changing the wheelbase, be sure to follow the driveline manufacturers recommendations for driveline length or angle

changes. Incorrectly modified drivelines can fail prematurely due to excessive vibration. This can cause an accident and severe personal injury.

Before changing the wheelbase, the driveline angles of the proposed wheelbase need to be examined to ensure no harmful vibrations are created. Consult with the driveline manufacturer for appropriate recommendations. Before the rear suspension is relocated, check the new location of the spring hanger brackets. The new holes for the spring hanger brackets must not overlap existing holes and should adhere to the guidelines in the FRAME DRILLING section of this manual. When shortening the wheelbase, the suspension should be moved forward and relocated on the original rail. The rail behind the suspension can then be cut to achieve the desired frame overhang. See FIGURE 5-1. FIGURE 5-1. Wheelbase Customization

5 FRAME MODIFICATIONS

Peterbilt Motors Company 5-2

CROSSMEMBERS

After lengthening a wheelbase, an additional crossmember may be required to maintain the original frame strength. The maximum allowable distance between the forward suspension crossmember and the next crossmember forward is 47.2 inches (1200 mm). If the distance exceeds 47.2 inches (1200 mm) after the wheelbase is lengthened, add a crossmember between them.

WELDING The frame rails are heat treated and should not be welded. The high heat of welding nullifies the special heat treatment of the rails, greatly reducing the tensile strength of the frame rail. If a frame member becomes cracked from overloading, fatigue, surface damage or a collision, the only permanent repair is to replace the damaged frame member with a new part. The following information is provided (for temporary emergency repair). Prior to welding a cracked frame rail, the area should be beveled (Vd out) to allow for a better weld. To prevent spreading of the crack, a 7 to 9 mm (1/4 in. to 3/8 in.) dia. hole should be drilled at the end of the crack. Widen the crack along its full length by using two hack saw blades together. When welding steel frames use the shielded arc method. When welding aluminum frames use either the tungsten inert gas (TIG) or consumable electrode method. Be sure to obtain full weld penetration along the entire length of the crack.

PRECAUTIONS

CAUTION:

CAUTION:

CAUTION:

Before welding, disconnect the negative terminal battery cable. Before welding, disconnect the alternator terminals. Failure to do so could result in damage to the voltage regulator and/or alternator. To prevent damage to electrical equipment, disconnect battery cables before arc-welding on a truck, and be sure that the welding ground lead is connected to the frame. Bearings and other parts will be damaged if current must pass through them in order to complete the circuit.

WELDING PRECAUTIONS: ALL ELECTRONIC ENGINES

Before welding on vehicles with electronic engines, the following precautions should be observed.

1. Disconnect all electrical connections to the vehicle batteries.

2. Disconnect all ECM connectors.

3. Do no use the ECM or engine ground stud for the ground of the welding probe.

4. Ensure that the ground connection for the welder is as close to the weld point as possible. This ensures maxi- mum weld current and minimum risk to damage electrical components on the vehicle.

5. Turn off key.

NOTE: Bosch ABS and Wabco ABS: Disconnect ECU.

SECTION 6 ELECTRICAL 389 FAMILY CONTROL UNIT IDENTIFICATION This manual provides service information covering models equipped with the multiplexed instrumentation system. Before attempting to make service repairs, the technician should be knowledgeable about the system design, components, operation and troubleshooting procedures for diagnosing instrumentation problems. Vehicle component inputs are sent to the ICU/CECU through the J1939 data bus or conventional wiring. The ICU/CECU interprets the various inputs and monitors/controls the functions for each input through the ICU/CECU software. Output signals from the ICU/CECU provide data for the gauges, warning lamps, audible alarms, and displays inside the cluster. When used in conjunction with the Electronic Service Analyst (ESA) diagnostic software tool, the technician can review fault codes stored in the ICU/CECU, verify whether the instrumentation is working properly and diagnose the root cause of the problem more easily. FUNCTIONAL DESCRIPTION-INSTRUMENTATION CONTROL UNIT CAB ELECTRONIC CONTROL UNIT (ICU/CECU) The heart of the multiplexed instrumentation system is the ICU/CECU. The ICU/CECU is located behind the radio at the center of the dash. See FIGURE 6-1.

ELECTRONIC SERVICE AGENT (ESA)

Introduced in 2005, the Electronic Service Analyst (ESA) is the diagnostic software tool that is used to simplify the troubleshooting of the new multiplexed instrumentation. Early multiplexing in Peterbilt trucks was for the instrumentation system only. The module was known as the Instrumentation Control Unit (ICU). Now, as multiplexing from this control module is being used for systems other than just the instrumentation, the module has been renamed the Cab Electronic Control Unit (CECU). The CECU is an updated ICU. It is still located behind the center console, but now includes a few more circuits to in- corporate the new features. ESA 2.0 is the tool for both. Identifying which control module is in the vehicle helps determine what features are present and also aids in troubleshooting. MODELSBUILD DATES IDENTIFICATION

IDENTIFICATIONS

Control module identification can be made using a few methods:

Searching using the Electronic Catalog (ECAT)

Connecting using the Electronic Service Analyst (ESA) 2.0

Dome light function ECAT Identification Using ECAT or ESA 2.0 are the easiest and most exact ways of determining the type of control module in the truck. ECAT provides a parts list as built and Bill of Materials in formation for each specific truck. The catalog is searchable, and contains the part number and identification of the trucks instrument panel control module.

ICU Part Number Q21-1029-X-XXX

CECU Part Number Q21-1055-X-XXX

Peterbilt Motors Company 6-3

ESA Identification Connecting using ESA 2.0 brings up a control module information window. In this window, the fourth line item is the Control Unit Type and identifies whether the truck has an ICU or CECU.

FIGURE 6-2. ESA Identification, Programming Date and Module Software Version

Dome Light Identification

The CECU system has an updated feature that delays turning the dome light off when you close the door. The previous ICU system did not have this function so the light turns off as soon as the door is shut. Therefore, if the dome light does not turn off immediately after all doors are shut, then the vehicle has a CECU system. If the dome light does turn off immediately, then the vehicle may be ICU OR CECU with this function disabled. In these cases, you will need to refer to ECAT for verification.

Comparison Chart

The following charts show the differences between the ICU and CECU.

The first chart provides an alphabetical listing of the features available for either an ICU or CECU. Since the CECU is an updated ICU, almost all of the features of an ICU are found in a CECU, except a few out dated options such as the pyrometer.

The similarity of the modules is easily seen in the second chart as well. This chart is an abbreviated connector pinout of each module. Since the same wiring connections are used for both modules, its easy to see that the CECU has more circuits to handle the increase in multiplexed features.

HOW MULTIPLEXED INSTRUMENTS WORK Multiplexed gauges receive signals through the Instrumentation Control Unit/Cab Electronic Control Unit (ICU/ CECU) located behind the center console. The ICU/CECU receives sensor signals either through the J1939 data bus or via conventional wiring sending signals from sensors that read actual pressures or temperatures. The ICU/CECU interprets this data and monitors or controls vehicle operation through the ICU/CECU software. The ICU/CECU then sends data to the gauges, warning lamps, audible alarms, and displays located inside the gauge clusters. The central instrument cluster (Figure 6-3) includes the speedometer (including odometer and trip meter) and tachometer (including engine hour meter and outside temperature display), plus pre-installed standard and/or editable warning light symbols called telltale decals mounted on the Icon Tray.

The Icon Tray slides into the bottom of the cluster. The standard Icon Tray covers most warning light requirements; editable icon lenses can be added for less common components that also require warning lights.

FIGURE 6-3. Central Instrument Cluster

INTRODUCTION This section provides service information covering Peterbilt Conventional Models equipped with the multiplexed instrumentation system. Before attempting to make service repairs, the technician should be knowledgeable about the system design, components, operation and troubleshooting procedures for diagnosing instrumentation problems.

Vehicle component inputs are sent to the ICU/CECU through the J1939 data bus or conventional wiring. The ICU/CECU interprets the various inputs and monitors/controls the functions for each input through the ICU/CECU software. Output signals from the ICU/CECU provide data for the gauges, warning lamps, audible alarms, and displays inside the cluster. See Figure 6-5.

When used in conjunction with the Electronic Service Analyst (ESA) diagnostic software tool, the technician can review fault codes stored in the ICU/CECU, verify whether the instrumentation is working properly and diagnose the root cause of the problem more easily.

CENTRAL INSTRUMENT CLUSTER

The central instrument cluster includes:

driver information display speedometer (including odometer and trip meter) tachometer (including engine hour meter and outside temperature display) pre-installed standard and/or editable warning light symbols called telltale decals mounted on the Icon Tray.

The Icon Tray slides into the bottom of the cluster. The standard Icon Tray covers most warning light requirements; editable icon lenses can be added for less common components that also require warning lights. The Driver Information Display, located at the top of the instrument cluster, displays vehicle information and warnings through a constant monitoring of the vehicle systems. The various functions may be accessed by navigating through menu screens using the menu control switch (rotational knob).

ICU/CECU ARCHITECTURE The software programming of the control module can be grouped into three main types:

Run Time (RT) - which acts as the operating system where all communication takes place. Programmable Logic Controller (PLC) Code - manufacturer specific programmed code and software that is

developed, accessible and editable. Vendor Module - blocks of code that are developed for specific manufacturers to allow other features to be

implemented more efficiently. See Multiplexed Instrumentation Block Diagram (Figure 6-6). To better understand how Electronic Service Analyst (ESA) functions and why there are current limitations on some of the multiplexed features, by explaining what ESA can see. Currently ESA can look at all information that is communicated between the RT and PLC Code portions of the programming. Any signals, be they inputs, outputs, or dataline signals, sent between the RT and PLC Code are visible to ESA. These are the signals that may be monitored and simulated using ESA. Limitations with the ESA program are found in the communications that go to the pre-developed Vendor Modules. Currently this information is not available for ESA to look at. That is why some features that have Vendor Module programming, such as the odometer and the message display, are not available to monitor and/or simulate through ESA.

The central instrument cluster receives input data from the ICU/CECU via the I-CAN data bus. When the ignition key is first turned ON, the cluster performs a calibration power on self-test. POWER ON SELF-TEST

Ignition key turned ON. The speedometer and tachometer gauge pointers move from pointing at zero, counter-clockwise to their

mechanical limit (approx. -8), remain there for 1 second and return to pointing at zero. At the same time, all LED indicators and telltales are switched on together, and then switched off together. A warning sound sequence is also activated five times without a break. The warning lamps in the cluster are all activated by the ICU/CECU, Three screens will sequentially display

warning icons on the Driver Information Display. The ICU/CECU receives direct wire inputs for all warning lamps with the exception of the Low Coolant Level warning and the Traction Control/Stability Control lamp. These lamp inputs are received via the J1939 (vehicle CAN) data link. The ICU/CECU typically receives the Trailer ABS warnings via the J1939 (Vehicle CAN) data link, however it can also be direct wired to the ICU/CECU from the ABS unit on the trailer, if required.

NOTE: Before replacing the ICU/CECU or any gauges, check the wiring and fuses, and perform the diagnostic tests using ESA to verify that you are not replacing a good component. COMMERCIAL VEHICLE SMART GAUGES (CVSG)

The right and left instrument panel gauges used with the multiplexed instrumentation are commonly referred to as Commercial Vehicle Smart Gauges (CVSG). Like the central instrument cluster, the 2-inch gauges also receive input data directly from the ICU/CECU. CVSGs are electronic and mechanical. The electronic CVSGs receive digital data from the ICU/CECU via the CVSG data bus. The mechanical gauges (i.e. suspension air pressure, etc.) are driven directly from the air pressure. Both types of gauges receive input signals from the ICU/CECU via a 4-wire daisy chained jumper harness that links one gauge to another. When the ignition key is first turned ON, all the electronic 2-inch gauges will perform a calibration power on self-test. POWER ON SELF-TEST

Ignition key turned ON. The gauge pointers move from pointing at zero, counterclockwise to their mechanical limit (approx. 5), remain

there for 1 second and return to pointing at zero. At the same time, all LED indicators are switched on together, and then switched off together.

Additional CVSG gauge information service technicians should be aware of:

2-inch electronic gauges receive their power from the ICU/CECU. Yellow = Power wire (9-16 volts) Green = Ground (Return) wire The ICU/CECU sends 2-inch electronic gauges information over a data link (blue wire) between the ICU/ CECU

and the gauge. 4-way jumper harnesses link each 2-inch gauge together. Yellow = Power wire Green = Ground (Return) Blue = Data link Brown = Backlighting (used for mechanical gauges only) Backlighting for 2-inch electronic gauges is sent from the ICU/CECU to the gauges via the data link (Blue wire). If the headlamps are on and the dimmer is turned to bright, you can scan the panel and tell which electronic

gauges are wired and functioning correctly.

6 Electrical 389 Family

Peterbilt Motors Company 6-11

If part of the panel has gauges backlit and some of the gauges are not backlit, the jumper harness wire between the gauges is probably not connected properly.

If a 2-inch electronic gauge has power (yellow wire) and ground (green wire) but is not receiving data (blue wire), then the red indicator lamp at the 6 oclock position of the gauge blinks after 30 seconds of waiting for data. This indicates there is an open or short in the blue wire between the gauge and the ICU/CECU.

If the red indicator lamp is on but the gauge is operational, it indicates the value is out of normal range. If a 2-inch electronic gauge has a short or open in the sensor wiring, the gauge needle moves 5 below the first

tick mark (approximately one needle thickness). Optional mechanical gauge (such as air suspension) needles are driven mechanically with air pressure. There is

no red warning lamp and the backlighting is through the brown wire from the ICU/CECU (a PWM input). The 4- way jumper harness is still used to pass all 4 circuits through the gauge to the next gauge in the chain.

Specialty CVSG gauges (such as the clock, PTO hour meter, and transmission display) are stand-alone gauges and are independent of the ICU/CECU.

INSTRUMENTS AND CONTROLS OPERATION

Before attempting to repair any instrumentation problems, the technician should have a complete understanding of how the instruments and controls operate. Speedometer The Speedometer indicates the vehicle speed in miles per hour (mph) and in kilometers per hour (km/h). Tachometer The Tachometer measures the engine speed in revolutions per minute (rpm). Air Filter Restriction Pressure The Air Filter Restriction Pressure gauge indicates the condition of the engine air cleaner and is measured by inches of water (H2O). A clean filter should register 7 in. H2O (may vary with system design) and a filter whose life is over registers approximately 25 in. H2O. Air Starter Pressure The Air Starter Pressure Gauge indicates the amount of air pressure in the air start reservoir. Ammeter The Ammeter monitors the vehicles electrical system and makes sure the system is in balance and operating normally. If not, it may be drawing power from the alternator (positive reading) or from the batteries (negative reading). Under normal conditions the ammeter will read nearly zero. Axle, Drive Oil Temperature The Drive Axle Oil Temperature gauges (front, rear, and center) indicate the temperature of the lubricant in the vehicles axles. Axle, Pusher Air Pressure, #1, #2, #3 The Pusher Axle Air Pressure gauges indicate the air pressure in each of the pusher axles suspension air bags. Axle, Tag Air Pressure The Tag Axle Air Pressure gauge indicates the amount of air pressure in the tag axle suspension air bags. Brake, Application Air Pressure The Brake Application Air Pressure gauge indicates how much air pressure is being applied from the foot brake valve or trailer brake hand valve to the air brakes. BrakeSaver Application Air Pressure (Export vehicles only) The BrakeSaver Application Air Pressure gauge indicates the amount of air pressure applied to the BrakeSaver hand control valve. BrakeSaver Oil Temperature (Export vehicles only) The BrakeSaver Oil Temperature gauge indicates the temperature in the BrakeSaver. If the oil temperature exceeds the maximum limits, a red warning lamp in the gauge turns on.

6 Electrical 389 Family

Peterbilt Motors Company 6-12

Engine Coolant Temperature The Engine Coolant Temperature gauge indicates the temperature of the engine coolant. If the coolant temperature exceeds the maximum limits, a red warning lamp in the gauge illuminates and an audible warning sounds. If the coolant temperature continues to rise, the Check Engine and/or Stop Engine lights illuminate. Under normal operating conditions the water temperature gauge should register between 165 and 205F (74 and 90C). Under certain conditions, somewhat higher temperatures may be acceptable. The maximum allowable temperature is 220F (104C) with the cooling system pressurized, except for certain engines. Engine, Oil Pressure If the oil pressure drops below the minimum pressure a red warning light in the gauge illuminates, the Stop Engine light illuminates and an audible alarm tone sounds. Engine Oil Temperature The Engine Oil Temperature gauge indicates the engine oil temperature. If the oil temperature exceeds the maximum limits, a red warning light in the gauge illuminates. Fuel Filter Restriction Pressure This gauge tells you the condition of the fuel filter by indicating the restriction from the fuel filter to the fuel pump. The restriction is measured by inches of mercury (in-Hg). Fuel Level, Primary/Secondary (if equipped) The Primary Fuel gauge and Secondary Fuel gauge (if equipped) indicate the approximate amount of fuel in each fuel tank. In addition to indicating empty and full, the gauge(s) also indicate the fuel level in graduated increments. When the fuel level for each tank is below 1/4 full, a red warning light in the gauge illuminates. General Air Pressure #1, #2 The General Air Pressure gauge(s) are used for customer installed component applications. General Oil Temperature The General Oil Temperature gauge(s) are used for customer installed component applications. Manifold Pressure (Boost) The Manifold Pressure (Boost) gauge indicates the power the engine is putting out by showing the amount of turbo boost. If the pressure indicated by the manifold pressure gauge goes down, there may be something wrong with the engine Primary and Secondary Air Pressure Gauge The Primary Air Pressure gauge indicates pressure in the rear braking system. The Secondary gauge indicates pressure in the front braking system. Each gauge indicates the amount of air pressure in each system in pounds per square inch (psi). On vehicles equipped with metric air pressure gauges, the gauge faceplate includes a kPa (major) scale and psi (minor) scale. If the pressure in either or both circuits falls below 65 psi, a red warning light in the gauge illuminates and an audible alarm tone sounds when the engine is running. Suspension Load Air Pressure, #1, #2 The Suspension Load Air Pressure gauge indicates the amount of air pressure in the air suspension air bags. When the vehicle is equipped with a second Suspension Load Air pressure gauge, the #1 gauge indicates the air pressure in the drivers side air bags. The #2 gauge indicates the air pressure in the passengers side air bags. Tractor Brake Application Air Pressure The Tractor Brake Application Air Pressure gauge indicates the amount of air pressure applied to the tractor brakes. Trailer Brake Application Air Pressure The Trailer Brake Application Air Pressure gauge indicates the amount of air pressure applied to the trailer brakes during brake foot valve and/or hand brake control valve applications. Trailer Reservoir Air Pressure The Trailer Reservoir Air Pressure gauge indicates the amount of air pressure in the trailer brake reservoir. Transfer Case Oil Temperature The Transfer Case Oil Temperature gauge indicates the temperature of the oil in the transfer case. If the oil temperature exceeds maximum limits, a red warning light in the gauge illuminates. Transmission Oil Temperature, Main The Main Transmission Oil Temperature Gauge indicates the temperature of the oil in the transmission.

6 Electrical 389 Family

Peterbilt Motors Company 6-13

Transmission Oil Temperature, Auxiliary The Auxiliary Transmission Oil Temperature gauge indicates the temperature of the oil in the auxiliary transmission. Transmission Retarder Oil Temperature The Transmission Retarder Oil Temperature gauge indicates the temperature of the oil in the transmission retarder. Voltmeter The Voltmeter displays the battery voltage. Normally, it shows 12 to 14V (volts). A red warning light in the gauge illuminates when an out of range condition exists.

SECTION 7 ELECTRICAL 579 FAMILY INTRODUCTION This section is written to provide information to the body builder when installing equipment into vehicles built with Multiplexed instrumentation. The new technology presented by NAMUX 4 level instrumentation integrates J-1939 CAN data communications to various equipment on the vehicle. This book is intended to address how to work in aftermarket equipment while still maintaining full functionality of the OEM vehicle. The most important advancement of NAMUX 4 instrumentation is the implementation of the Cab ECU controlling air operated aftermarket devices. While it is still possible to wire completely outside of the Cab ECU system, utilizing the CECU functions will make a cleaner installation and will maintain OEM functionality. NAMUX 4 expands controls to air operated devices by receiving input from dash switches, remote (aftermarket) switches, sensors mounted to the aftermarket equipment and other vehicle parameters (engine speed, transmission status etc.) With the proper programming, the CECU will then process the inputs and will create a J-1939 Data instruction which is communicated to another controller outside the cab called the Chassis Node. This chassis node receives the instruction and connects 12V power to an air solenoid. 12V power will open the solenoid and supply air pressure to that air circuit.

FIGURE 7-1. NAMUX 4 System Diagram

In addition to NAMUX 4 technology, the vehicle electrical harness has been redesigned to minimize weight and reduce various connectors (which have been proven to increase the opportunity for electrical malfunctions which also increase the amount of time to troubleshoot). What this means for the aftermarket installer is that there is a limitation to modifying a vehicle with aftermarket equipment if the vehicle was not originally specified for those options from the factory. To the aftermarket installer, more time will be spent installing pins and routing wires instead of simply installing jumper harnesses if the vehicle was not specified with customer installed equipment from the factory. For example, vehicles ordered with a customer installed PTO will have connectors on the vehicle for aftermarket connectors. A vehicle specified with standard radio will not have a pigtail for premium sound speakers.

DIAGNOSTICS CONNECTOR

For Model Year 2017 (Calendar Year 2016) engines, Peterbilt utilizes a faster connection for diagnostics. Before this time frame, a 250 kbps baud rate was utilized with a black Type 1 diagnostics connector. After this timeframe, U.S. and Canadian market chassis (not export engines or natural gas engines) will utilize a new green Type 2 connector at 500 kbps band rate. This new connection will utilize the faster connection specifically for OBD CAN diagnostics on the C and D terminals, while still broadcasting the Vehicle CAN on the F and G terminals (see figure below for comparison). In order to connect properly, a Y adapter cable is required to connect various service tools (DAVIE, ESA, Eaton ServiceRanger, Allison DOC, Wabco Toolbox). On the Y adapter, both green (new) and black (old) connections are provided to allow compatibility with 2016 and later as well as pre-2016 chassis without the need to remove the adapter.

BODY BUILDER CONNECTION POINTS

Becoming familiar with the various connectors available to the aftermarket installer is important. This section contains reference information for the connectors that are used to add equipment.

HARNESS DESIGN

The 579 and the vocational 567 are designed and manufactured with a cab harness that is chassis specific. The new design minimizes the number of connectors which improves routing, reduces electrical problems and reduces diagnostic time when servicing. The new design, however, changes the way electrical components are added to the vehicle for final use customers. The after-market installer will have several options available:

1. Ensure that the vehicle is ordered and specified with the equipment installed or at least have furnish by owner provision.

2. Install electronic accessories outside of the CECU network, direct power from the power distribution center and no splicing into the cab harness.

3. Route new wires and install pins to the designated pin location on all connectors.

It is imperative that the installer never splice into a cab harness for signal or power purposes.

Remote Throttle and Remote PTO Control

The body builder will need to find the 12-pin remote throttle connector, located in the engine compartment on the engine harness. See the PTO Section for additional information

FIGURE 7-4. 12 Pin Connector

SPARE POWER

Spare power connector P096 is located on lower left side of dash behind key switch or kick panel. The mating harness is available from PACCAR parts with pre-labeled pigtails, P92-8916-000000001.

AIR SOLENOIDS Air solenoids are the devices that translate the electrical signal into physical change that controls the air pressure in various circuits. The air solenoids are mounted to a bracket outside the cab. The solenoids are designed to stack on each other so that they share a common air supply rail which reduces the amount of air lines on the vehicle. Air solenoids used on the vehicle are both of Latching and Non Latching types.

TABLE 7-3. Air Solenoid Types

Latching Requires a signal voltage to close or open a solenoid. Will remain in position if power is disconnected. Physically, these require 2 spots on the bank compared to a non-latching valve.

Non-latching Requires 12v to change a valve from its normal position. Will revert back to its normal position if power is disconnected.

For safety reasons, certain circuits are designed with latching type solenoid valves. These circuits include but are not limited to:

1. Air suspension dump (tractor and trailer) 2. 2 speed rear axle control 3. Liftable axle controls (both on the vehicle and on the trailer) 4. Workbrakes for winches

The aftermarket installer/final vehicle manufacturer needs to decide what type of valve to install and ensure that the documentation to the operator provides them with enough understanding of how the customized switches work.

NOTE: General air accessory, when ordered from the factory, is wired to a non-latching solenoid. Therefore, general air accessory options will reset when the ignition is turned off. If a latching solenoid is installed on a furnish by owner air accessory, the installer will need to document how the system operates.

REMOTE THROTTLE Remote control of the PTO is performed through the 12-pin remote throttle connector on the engine harness. These are pins 1, 2, and possibly 6 (depending on engine) on J111_.

The 2010 and 2013 MX engine controller port (J2 pin 21) will report a PTO active when driven high (+12V DC). Since PTO and pump mode signals are low when active a relay is needed to convert the low signal to a high signal. When a PTO is specified on a chassis the MX engine harness will contain the optional remote throttle/PTO 12-way connector and cap (P111C/J111C).

HOW DO I... This section is created to provide specific instructions to completing the installation. Please refer to the section for dash board to access dash panels for switches and gauges.

INSTALL A MULTIPLEXED INSTRUMENT Generally, installing gauges and switches into the dash board will require installing pins in a connector of the CECU if a connector is not present. The CECU will then need to be re-programmed to accept the new instruments.

INSTALL AND AIR OPERATED EXTERNAL DEVICE After installing the instruments in the cab, and before re-programming the CECU, the electric over air solenoid will need to be installed onto the solenoid bank. These instructions do not apply to vehicles that have all spaces on the solenoid bank already in use by some device.

FIGURE 7-42. Install Solenoid

Once the solenoid is installed, wiring must be installed between the chassis node and the solenoid. Then the ground wire should be installed between the solenoid and the ground splice. Air supply to the solenoid bank is already in place, but air lines from the output of the solenoid to the air operated device will need to be installed. RE-PROGRAM THE CECU The CECU may be programmed by using the software Electronic Service Application (ESA). The engine will need to be programmed using the engine specific software. INSTALL NEW TELLTALE ICONS INTO THE INSTRUMENT CLUSTER To install new telltales into the instrument cluster, the cluster will need to be removed from the dash. The instrument panel trim is removed after removing the panel immediately to the right of the instrument cluster. Then 4 fasteners hold the instrument cluster to the dash structure. Refer to the Dash removal chapter to identify the location of the telltale icon tray.

ACCESS THE SOLENOID BANK AND CHASSIS NODE Accessing these two items will require opening the hood and removing the fairings. After the fairings are removed, the battery box/batteries will need to be removed from the frame rail. This process will provide open access to the chassis node, solenoid bank and all electrical connectors. The solenoid bank and chassis node may be removed without removing the battery box, however this will not provide access to the splice block needed for ground connection. GET THE SUSPENSION AIR BAGS TO DEFLATE WHEN THE PTO IS ON Dump body applications will be able to utilize a function such that when the PTO is active (and the dump body is being lifted), the body is sitting on the suspension bump stops. This provides a more stable platform than the airbag. EE_PAR_EOA_bool_SuspensionDumpWithPTOActivation enables this functionality. If any switch is configured to be a PTO switch and any switch is configured to be Suspension Dump, the Suspension Dump switch shall be considered as active. All existing Suspension Dump interlocks must still pass for the suspension to be dumped. INSTALL ELECTRIC OVER AIR SOLENOIDS The models 567 and 579 utilize electric solenoids to control air supply to various air operated functions and equipment on the chassis. The solenoids will be located either under the cab just behind the drivers side front cab mount for chassis built prior to 1/1/2016 as shown in Figure 7-44, or behind the back of cab crossmember for chassis built after 1/1/2016 as shown in Figure 7-45. The solenoid bank consists of two types of solenoids, latching and non-latching. An example of both can be seen below in Figure 7-43. Latching solenoids take up two spots on the solenoid bank and require a 12V signal to close or open and will remain in the position it is in if power is disconnected. Latching solenoids are typically used where the circuit requires a built in safety mechanism that would require the air supply to stay connected even with the ignition key in the off position. Non-latching solenoids require a 12V signal to change the valve from its normal position and will revert back to its normal position if power is disconnected. Some examples of circuits that will always be on a latching type solenoid include the air suspension dump, 2 speed rear axle control, liftable axle controls, and workbrakes for winches.

FIGURE 7-43. Diagrams of Latching and Non-Latching Solenoids

The solenoid bank contains up to 10 solenoid positions. Latching solenoids will occupy 2 spaces while non-latching solenoids occupy only one position. Positions 1-8 are controlled by multiplexed signals and are wired directly to the chassis node control unit. Position 9 and 10 are hard wired and can be controlled directly by a dash switch. Latching solenoids may only occupy positions1 & 2, 3 & 4, or 6 & 7. Non-latching solenoids may be placed in any position available.

INSTALL AND REMOVE SOLENOID BANK ASSEMBLY Disassembly of the solenoid bank to add or remove solenoids is simple. Remove any bolts holding the solenoid bank to the mounting location. Remove the two screws from the end cap, and the screws from in between the solenoid(s) you want to remove. Twist the solenoid to unlock it and solenoid should be free as shown in Figures 7-48 and 7-49.

PROGRAM SOLENOID When programming a non-latching solenoid, the parameter in ESA will match the position that the solenoid is located in and the pigtail that solenoid is connected to. In the example shown in Figure 7-50, a non-latching solenoid is connected to the pigtail for EOA SOL #1 and corresponds to the parameter Electric Over Air Function 01 to control an interaxle diff lock with a speed interlock. The pigtail for EOA SOL #2 and corresponds to the parameter Electric Over Air Function 02 and is set to control PTO #1 without an interlock.

FIGURE 7-50. Example of EOA Solenoid Programming

When programming a latching solenoid, it will require two pigtail connectors per solenoid. In the example shown in Figure 7-51 an air suspension dump latching solenoid with a speed interlock is in positions 1 & 2 on the solenoid bank and connected to the pigtails for EOA SOL #1 and EOA SOL #2. The lowest position of the pigtails will be programmed as the latching function, while the higher number pigtail will be programmed as None.

OPERATE PTO EOA For chassis equipped with manual or Eaton automated transmission the PTO air supply will be EOA controlled. The PTO EOA solenoid is a non-latching solenoid and may be placed in various solenoid positions depending on chassis options. If the PTO option ordered is a double acting PTO, the PTO air supply will still use a single non-latching EOA solenoid, but an inversion valve will be included on the chassis. The inversion valve will be mounted on the transmission. Plugs will be used on most F/O PTO plumbing.

ALLISON TRANSMISSION EOH FUNCTIONALITY AND CONNECTION Chassis equipped with an Allison transmission that will be fitted with a transmission driven PTO will use electric over hydraulic control for the PTO. When ordered properly, the Allison transmission harness will have one of two connectors to plug into the PTO solenoid. Referencing Figure 7-54 on the next page, connector P623 will be on chassis ordered with a furnished by owner Muncie PTO, and connector P621 will be on chassis ordered with a furnished by owner Chelsea PTO. If neither of these options is specified, the PTO chassis side wiring will have to be added by the body builder. The cab side wiring will be tied to the option code for the electric over hydraulic (EOH) dash mounted switch. Explanation of Circuit Functionality Please reference the diagram on the following page shown in Figure 7-54. The dash switch when switched to the PTO ON position, sends a 12V (+) signal out to the TCU pin 43 as well as pin 30 of the Allison 130 relay. This 12V signal is also sent out to the pin 33 of the cab harness to the transmission harness connector. Pin 33 is not used for anything as configured from the factory. The Allison TCU will trigger pin 85 to close the Allison 130 relay, thus sending a 12V (+) signal out via pin 87 to pin B on connector P621 or P623 on the Allison transmission harness. If neither of these connectors was optioned on the chassis (see above), then the PTO up fitter will need to pick this signal up at pin 34 of the firewall connector J620. Pin A of connector P621/P623 is a permanent ground signal. This is fed from pin 55 of the J620 firewall connector.

SECTION 8 POWER TAKE-OFF (PTO) INTRODUCTION A Power Take Off (PTO) provides a way to divert some or all of the trucks engine power to another component. There are a wide variety of PTO options available on a Peterbilt that are described below.

FIGURE 8-1. Power Take-Off Locations TRANSMISSION MOUNTED PTO GENERAL MANUAL TRANSMISSIONS This is the most common type of PTO that is used. On a manual transmission there are two locations for PTOs. On medium duty transmissions there are 6 bolt PTO locations on the right and left (Figure 8-2). On heavy duty manual transmissions there is a 6 bolt PTO on the right and an 8 bolt PTO on the bottom left (Figure 8-3). There are also some options for a thru shaft or extended countershaft PTO. On a thru shaft PTO, the counter shaft extends out through the back of the transmission which can be used to power a PTO (Figure 8-4). When using a thru shaft PTO the vehicle must be specd with the correct option as not all transmissions will be set up for use with thru shaft PTOs. For more information go to www.roadranger.com and enter PTO Installation Guide in the search bar in the upper right corner.

FIGURE 8-2. MD Manual Transmission FIGURE 8-3. HD Manual Transmission FIGURE 8-4. Thru Shaft PTO

8 POWER TAKE-OFF (PTO)

Peterbilt Motors Company 8-2

AUTOMATIC TRANSMISSIONS On Allison transmissions there are two locations for PTOs. The Allison 4000 series has PTO locations at 1 and 8 oclock viewed from the back of the transmission. See Figure 8-5. The 4000HS transmissions do not have any PTO locations. The 3000 series Allison transmissions have PTO locations at 4 and 8 oclock (Figure 8-6). For more information on using PTOs with an Allison transmission go to www.allisontransmission.com and refer to the Rugged Duty Series Brochure and PTO Request Flyer which is available in a 1000/2000 version and a 3000/4000 version. Some PTO configurations will have clearance issues with other components on the truck. With manual transmissions, a 6- bolt PTO on the right will typically clear most components when the DPF and SCR are under the cab. This is also true when 30 and 45 degree adapters are used. The 8-bolt bottom mount PTO will not have any issues unless you are running a driveshaft back to another component and the truck has a crossover style exhaust. In this case, the DPF and SCR would block any routing for the driveshaft. If a wet kit is used in this scenario there is enough room to mount the PTO and the hydraulic pump without interfering with the exhaust. On Allison 4000 series transmissions, most PTOs will fit in the 1 oclock position without interfering with the cab. If a wet kit is used here, the dipstick housing will most likely need to be modified as it runs over the top of the transmission to the driver side of the vehicle. The PTO in the 8 oclock position is typically ok. The same issue with crossover exhaust would apply here as well. There are some scenarios where the PTO will be very close to or could interfere with the rear spring shackle on the front suspension. This problem can occur on vehicles with a set-back front axle and the problem is amplified on the short hood models.

TRANSMISSION MOUNTED PTO 579 FAMILY This application guide indicates if a PTO has sufficient clearance to truck components in various mounting configurations. A green "ok" indicates that there is sufficient clearance to other truck components. A red "x" indicates that there minimal or no clearance and the application is not recommended. The truck components investigated in this guide include frame rails, Set Back Front Axle (SBFA) rear shackle, SBFA Front Air Suspension (FAS) rear shackle, over-bell frame brace, coolant return manifold, transmission clutch actuator, and exhaust system components. Usage Notes:

1) This application guide is only applicable to 579/567 trucks.

2) Only the specified PTO configurations have been analyzed.

3) Horizontal crossover exhaust limits access behind PTO's for shaft drives and other PTO attachments.

4) Eaton FR transmissions require the use of a 30 adapter when installing Chelsea or Muncie transmission PTO's in the right hand position.

5) Eaton RT & Ultrashift Plus transmissions require the use of a 49 adapter when installing Chelsea

transmission PTOs in the right hand position.

6) Eaton RT & Ultrashift Plus transmissions require the use of a 55 adapter when installing Muncie transmission PTOs in the right hand position.

7) Eaton transmissions require the use of a 6 to 8 Bolt adapter when installing a 6 bolt PTO in the bottom

position. PTO CONTROLS The 579/567 models have been designed to use electric in-dash switches to control air solenoids which engage/disengage transmission PTOs. This system allows for increased control and interlock opportunities. This also keeps air lines for transmission PTO controls from routing inside the cab. In cab air valve actuators for transmission PTO control are still available and are located on the cab floor on the LH side of the drivers seat. Air valve style transmission PTO actuators should not be installed on the dash due to the difficulty of air-line routing. Customer installed transmission PTO controls for use with customer installed transmission PTO's include a chassis and dash harness pre-wire to ease the installation of in-dash transmission PTO controls at the body builder. It is strongly recommended that the truck be coded for this if transmission PTO(s) could be installed after initial in-service date.

FRONT ENGINE PTO Front engine PTO (FEPTO) is commonly used in mixer, snow plow, and crane applications. When a FEPTO is specd on a truck, the cooling module moves up to allow for a shaft to be bolted to the front of the crankshaft and extend out to the front of the truck. The vehicle can be specd with a 1350 flange adapter to simplify installing the FEPTO shaft. The frame rails will be extended out to mount a hydraulic pump, snow plow or outriggers. There are options for either a 27.8 or a 22.4 frame extension. See Figures 8-12 to 8-14 for frame extension dimensions.

REAR ENGINE PTO Rear Engine PTO (REPTO) is commonly used in cement mixer and feed lot applications. The REPTO is driven off the rear gear train on the engine. There is a 1350/1410 flange on the bell housing in the 1 oclock position that can be used to attach a hydraulic pump or driveshaft. See Figure 8-15 for an example. The REPTO flange will always be turning when the engine is running and the output rotation is the same as the engine. The Cummins ISL9 and PX-9 REPTO turns at a rate of 1.15:1. The Cummins ISX-12 REPTO turns at a rate of 1.32:1. The Paccar MX-13 REPTO turns at a rate of 1.2:1. The Paccar MX-11 REPTO turns at a rate of 1.3:1.

PTO INSTALLATIONS 389 FAMILY Standard PTO operation is also called cab PTO. With this feature, the operator can set the engine to pre-programmed set speed(s) and ramp the engine speed up and down with the set/resume switch. To control the PTO there are various dash switches that we offer. Standard with every vehicle is the Cruise Control/PTO on off switch and the Set/Resume switch. There are also several additional PTO control switches that can be used. The PTO control switch will be plumbed with air lines that will be plugged at the firewall bulkhead. See Section 7 for PTO dash switch plumbing and firewall bulkhead locations. With the MX engine when the PTO dash switch is engaged a pressure switch on the air lines under the dash will send a signal to the engine to go into PTO mode. On Cummins engines, when the cruise control switch is activated and all parameters set in the ECM for PTO mode are met, the engine will go into PTO mode. In this mode, the engine will respond to all PTO mode parameters that have been programmed into the software. These parameters can be changed with INSITE on all Cummins engines and DAVIE on all MX engines. There is a PTO light on the dash that should be wired to the PTO to inform the operator when the PTO has engaged or disengaged. This should be wired to the PTO output, not just a dash switch or PTO enable circuit. The wire can be found in the right hand rail in the area of the transmission. The wire is labeled WHT1513 PTO Circuit. On Allison transmissions, the PTOs will require an electric signal. We do not currently offer an electric PTO switch for the 389 family, but there are several options available. The most common method of getting an electric signal for the PTO is to get a factory air switch and install a pressure switch on the air line. It is recommended to provide a 12 volt signal to the transmission control module (TCM) and have the TCM programmed to check for specific requirements such as engine speed, gear selection, output speed etc. before engaging the PTO. If the TCM logic is bypassed and the PTO is engaged directly it could cause damage to the PTO and the transmission. Contact your local Allison rep for more information.

PTO INSTALLATION 579 FAMILY PTO CONTROLS The 579/567 models use Electric Over Air (EOA) or Electric Over Hydraulic (EOH) controls to supply the signal to activate the PTO. The EOA controls are recommended for manual or automated transmissions. The EOH controls are recommended for automatic transmissions. The EOA controls feature a valve that is located under the left hand side of the cab as shown in Detail B of Figure 8-20. The valve converts an electrical signal from the PTO dash switch into an air supply. This air supply is then plumbed to the PTO activation port for manual transmissions, or a pressure switch for automatic transmissions (automatic transmissions require an electrical signal for PTO engagement). The EOH controls will send an electrical signal from the PTO dash switch to the transmission harness that will activate the PTO function of the transmission.

FIGURE 8-20.

The EOA controls are used to engage the PTO, but to get the engine to go in to PTO mode a signal must be sent from the PTO to the engine. When pin 2 (PTO engaged signal) of the chassis PTO connector is grounded, the engine will go to PTO mode. This can be done by using the PTO activation switch on the PTO to close a circuit between pin 2 and pin 1 (chassis ground) of the chassis PTO connector. This will also activate the dash icon to notify the operator PTO mode is engaged. The chassis PTO connector is located inside the rail adjacent to the transmission as shown in Detail C of Figure 8-20.

8 POWER TAKE-OFF (PTO)

Peterbilt Motors Company 8-13

PTO OPTIONS Single acting PTOs have a single air control. A single chassis node output controls the air solenoid, and the air pressure engages the PTO, and the lack of air pressure at the control port disengages the PTO from the driveline. Double acting PTOs have a dual air control. One air controls the engagement, and one air control controls the disengagement. This can be achieved one of two ways:

1) A Single Acting PTO is configured. The engage air control port is connected to the chassis node output and a pilot inversion valve in the chassis air plumbing is connected to the second disengage air control port

2) Two chassis node outputs control the PTO. One chassis node output and solenoid is connected to the engage air control port of the PTO, and one chassis node output and solenoid is connect to the disengage air control port.

Reversible PTOs have three different operational states:

1) Inactive, not engaged to driveline, no air control ports active 2) Main Direction, engaged to driveline, Main air control port pressurized 3) Opposite Direction, engaged to driveline, Opposite air control port pressurized

The CECU software is written as part of 3-position switch design strategy. This 3 position switch prevents the possibility that both inputs are active at the same time. CECU INTERFACE WITH PTO CONTROLS If the vehicle is specified with a PTO installation from the factory a protected PTO on/off switch will be present in the dash. If the truck has the option for EOA PTO controls, it will connect to the instrument panel harness with a switch connector labeled "EOA x" x being a number between 1 and 10. If numbered between 1 and 8, the switch will be connected to the Cab ECU.

FIGURE 8-21. Chassis Node / EoA Diagram

8 POWER TAKE-OFF (PTO)

Peterbilt Motors Company 8-14

If numbered 9 or 10 the switch will be wired directly to EOA valve 9 or 10.

FIGURE 8-22. Interlock Example Diagram

If the Cab ECU detects the switch in the on position and if applicable, the park brake interlock is validated by the Cab ECU, the Cab ECU will send a mux signal to the chassis node via F-CAN. The EOA valve will be the same number as on the dash switch. Electronic Service Application (ESA) can be used to add or remove the PTO engage park brake interlock. Depending on the application and the PTO type, the switches and wiring may differ.

FIGURE 8-23. PTO Control Example Diagram

For single acting PTO, the chassis node will energize the coil on the EOA valve allowing air to engage the PTO. For dual acting PTO, the PTO's pilot valve will provide the air function to switch the air between engage and dis- engage. If the PTO is a forward/reverse PTO:

A protected PTO forward and a protected PTO reverse switch will be present in the dash. Each switch controls a separate EOA solenoid, each solenoid is dedicated to either forward or reverse.

If the Cab ECU detects both the forward and reverse switches in the on position the Cab ECU will ignore the switch input for the second switch thrown and provide a message in the cluster display informing the operator of the non-valid switch configuration.

PTO AND PUMP MODE WARNING

Instrument panel wiring:

Pump mode warning lamp is an editable telltale and requires a diode. PTO engaged warning lamp Peterbilt is an editable telltale and requires a diode. The diodes prevent relay coil back feed from driving the CECU input high which could activate the warning lamp (bi-stable input) giving false indications. CK_K10 spare relay #3 is used to power the PTO hour meter whenever the PTO engaged warning lamp is on.

ENGINE PTO SIGNAL The ISX engine controller port (J2 pin 94) will report a PTO active when driven low (grounded). When a PTO is specified on a chassis the ISX engine harness will contain the optional remote throttle/PTO 12-way connector and cap (P111A/J111A). The chassis harness will also contain a 4-way P198 connector in the chassis harness, as noted in Detail C of Figure 8-20. The MX engine controller port (J2 pin 21) will report a PTO active when driven high (+12V DC). Since PTO and pump mode signals are low (grounded) when active, a relay is needed to convert the low (ground) signal to a high (+12V DC) signal. This relay is installed below the left hand side of the cab near the chassis node. When a PTO is specified on a chassis the MX engine harness will contain the optional remote throttle/PTO 12-way connector and cap (P111C/J111C). The remote throttle/PTO 12-way connector is located on the back, left hand side of the engine as shown in Detail A of Figure 8-20. See Figure 8-24 for pin out information of the 12-way connector. There are also 16-way and 23-way connectors available for setting up dual station controls or other high content applications. See Figure 8-27 for the 16-way pin out information and Figure 8-28 for the 23-way pin out information. The CECU parameters for REMOTE PTO CONTROL and REMOTE THROTTLE CONTROL may need to be enabled. There are two common methods of utilizing remote engine speed controls:

1) A 5V variable signal can be used to control the engine speed via a potentiometer. For this configuration the CECU parameter for REMOTE THROTTLE may need to be activated.

-For the MX engine, pins 3, 4 and 10 can be connected to the potentiometer to convert the 5V signal to a remote throttle signal. -For Cummins engines, pins 4, 10 and 11 can be used the same way as described above for the MX engine.

2) The engine speed can be bumped up or down using momentary switches or preset speeds. For this configuration the CECU parameter for REMOTE PTO may need to be activated. -For the MX engine, momentarily connecting pin 8 to pin 2 will increase the engine speed. Momentarily connecting pin 8 to pin 1 will decrease the engine speed. -For Cummins engines, the engine will go to the first set speed when PTO mode is initially activated by applying ground from pin 3 to PTO ON/OFF pin 5. If this connection is broken and reapplied within 0.5 seconds, the engine will go to set speed 2. If this is done again, the engine will go to set speed 3 and so on. There are up to 5 preset speeds that can be modified using INSITE. If the connection is broken longer than 0.5 seconds and then reapplied, the engine will go back to set speed 1.

CHASSIS HARNESS WIRING MX ENGINES

The MX PTO relay is required to convert the low PTO engaged signal to a high signal for the MX ECU. The MX PTO relay (P27-1151) is used to convert this signal. The MX PTO relay coil receives 12V IGN power from fuse E_E9 body IGN from pin 7 of the MX engine harness PTO/remote throttle connector (P111). When a PTO engages the PTO engage circuit has a path to ground. This ground path allows current to flow through the MX PTO relay coil. When the MX PTO relay is active the MX ECU receives a high input signaling that the PTO is engaged. EATON AUTOMATED TRANSMISSIONS: For Eaton Ultrashift Plus and Advantage automated transmissions, the transmission ECU requires an isolated PTO engaged signal. The Eaton PTO relay (P27-1151) is used to isolate the PTO engaged signal to the transmission ECU. The Eaton PTO relay coil receives 12V IGN power from fuse E_E9 body IGN from pin 7 of the engine harness PTO/remote throttle connector (P111). PTO engage circuit has a path to ground. This ground path allows current to flow through the Eaton PTO relay coil. When the relay is active pins 34 and 18 on the transmission controller are shorted providing the PTO engaged signal to the transmission ECU.

FIGURE 8-33. Relay Wiring Diagram NAMCO SPLIT SHAFT PTO/TRANSFER CASE UNITS

Note: since the Namco option uses relays in the same position as the snow plow option these options cannot be called out together. For chassis with a Namco split shaft PTO/transfer case several configurations are available which require up to three relays to convert the engaged signal to drive the PTO, pump mode and front axle declutch warning lamps. The three possible clutch configurations: rear axle & front axle, rear axle & PTO, rear axle, PTO and front axle.

PTO: When the PTO is not engaged the Namco sensor sends a high signal on pin 2 (J195) energizing the Namco PTO relay coil (P27-1150). When the Namco PTO relay is energized no signal leaves the relay. When the PTO is engaged the sensor output goes low. The Namco PTO relay coil de-energizes and the PTO warning lamp is grounded. Pump mode: (rear axle declutch) When the Namco axle clutch is in road mode the Namco sensor sends a high signal on pin 4 (J195) energizing the Namco pump relay coil (P27-1150). While the Namco pump relay is energized no signal leaves the relay.

8 POWER TAKE-OFF (PTO)

Peterbilt Motors Company 8-24

When the rear axle is declutched for pump mode the sensor output goes low. The Namco pump relay coil de- energizes and the pump mode circuit is grounded. Front axle clutch: When the Namco front axle clutch is not engaged the Namco sensor sends a high signal on pin 5 (J195) energizing the Namco front axle clutch relay coil (P27-1150). While the Namco pump relay is energized no signal leaves the relay. When the front axle is clutched for front axle power the sensor output goes low. The Namco pump relay coil de-energizes and the front axle clutch circuit is grounded. Chassis with a Namco split shaft PTO will also be provided with a 6-way connector to connect to the Namco sensor jumper harness (J195).

Three circuits are passed to the IP harness, PTO, pump mode sense, front axle clutch via the chassis to IP connection (J161/P033). Two 12-way connectors are provided to connect to the MX or ISX engine harness remote throttle/PTO connector (P197/J197). The Eaton PTO relay, MX PTO relay, Namco PTO relay, Namco pump relay and Namco front axle clutch relay are located in a 40-way sealed relay box mounted behind the chassis node. Fabco split shaft PTO/transfer case jumper harness:

There are 4 different split shaft PTO/transfer case jumper harnesses. They account for, rear & front axle, rear & one PTO, rear & two PTO's, rear & front & one PTO configurations.

PTO sensor to chassis harness connector (P198/J198):

The chassis harness provides for a 4-way connector to connect to a PTO sensor harness. It will always be capped for shipment to the plant (P198/J198).

Pin 1 - wht4395, provides vehicle ground for 2-pin PTO engagement switches Pin 2 - gra4395, PTO engaged signal. When low activates the PTO engaged warning lamp.

There are a number of parameters that must be set to enable PTO functionality on PACCAR MX Engines. The MX Programming Guide explains how to set these parameters for your application in section 12 Power Take-Off Engine Speed Control (PTO Mode).

This section explains how to configure trucks with MX engines in one of the four PTO options as listed below:

1. Stationary In-cab PTO control

2. Mobile In-cab PTO control

3. Stationary Remote PTO with hardwired control

4. Stationary Remote PTO control over BCAN

5. Stationary Remote PTO with TSC1 control Depending on the configuration used, it may require one or more of the following:

1. Electrical Wiring Installation

2. Reprogramming of MX Engine using PEP and DAVIE

3. Reprogramming of CECU using ESA

This section explains only the parameter configurations that are specific to one of the four options listed above. There are a number of common parameters that must be configured which are explained in section 12 Power Take-Off Engine Speed Control (PTO Mode) of the MX Programming Guide. PTO Controls Utilizing TSC1 Messaging DISCLAIMER: PACCAR is not responsible for equipment damage or personal loss related to accidental or intentional misuse of TSC1 functionality

*As far as message rates are concerned, PTO should always be sent from the body builder controller at 100ms. The TSC1 message must be sent at 10ms when the OCM (SPN 695) is broadcast at 0x1,0x2,or 0x3. If the last broadcast was OCM = disabled (0x00) then the message no longer needs to be sent at 10ms until the next time it is required. This is preferred to minimize bus loading. WARNING All configured PTO safeties, limits and interlocks will be observed if the prescribed message format

is followed. Using messages or format other than the PACCAR PTO TSC1 Message Requirements may result in unexpected vehicle and equipment behavior.

If customer BBM is not powered on at ignition key on a low rate fault CECU configuration is not necessary for standalone TSC1 PTO control

IN CAB PTO CONTROL

FIGURE 8-48. In-Cab PTO Control

To activate In-Cab PTO Control, there is a PTO switch in the cab that needs to be turned ON by the operator. This PTO ON/OFF switch is hardwired to the CECU which activates the PTO equipment. The PTO engagement feedback signal wire must be connected to CECU and Engine as shown in the diagram. Refer to Electrical section of this manual for more information on wiring. When the PTO switch is ON and the engine receives signal that PTO is engaged, the engine changes its state to PTO Mode and the CECU will activate the PTO telltale on the cluster. For more information on engine behavior in PTO mode, please refer MX Programming Guide. The engine speed in PTO Mode can be controlled by the cruise control switches or the accelerator pedal inside the cab depending on how the MX Engine is configured. This is explained in Section 1.2 in the BBM. Refer to the MX programming guide for further details on engine speed control in PTO Mode. CECU Configuration using ESA To configure In-Cab PTO Control, the following parameters must be set in CECU using ESA as shown:

REMOTE PTO CONTROL OVER BCAN WITH HARDWIRED PTO ENGAGEMENT TO ENGINE

FIGURE 8-52. Remote PTO Control over BCAN with PTO ON/OFF Switch Hardwired to CECU

To activate Remote PTO Control over BCAN as shown here, there is a PTO switch in the cab that needs to be turned ON by the operator. This PTO ON/OFF switch is hardwired to the CECU which activates the PTO equipment. The PTO engagement feedback signal wire must be connected to CECU and Engine as shown in the diagram. Refer to Electrical section of this manual for more information on wiring. When the PTO switch is ON and the engine receives signal that PTO is engaged, the engine changes its state to PTO Mode and the CECU will activate the PTO telltale on the cluster. For more information on engine behavior in PTO mode, please refer MX Programming Guide. The engine speed is controlled by the customer installed PTO Control on the BBM. The CECU gets the Set, Resume and Accelerator signal from the Body Builder Module over B-CAN. The CECU sends these signals to the Engine via V-CAN using standard SAE messages as shown in Table. The PTO engagement feedback is hardwired to the CECU and the engine using 12-pin PACCAR connector as explained in Electrical section of this manual.

SECTION 9 AFTERTREAMENT INTRODUCTION The following section is designed to give you information regarding the exhaust and after-treatment systems on Peterbilt chassis. All Peterbilts equipped with 2017 emission level engines will utilize Selective Catalyst Reduction (SCR). SCR is a process in which Diesel Exhaust Fluid (DEF) is injected into the exhaust downstream of the engine. DEF is converted to ammonia by the heat of the exhaust system. Inside of the SCR canister a catalyst causes a chemical reaction to occur between the ammonia and NOx, turning it into water and nitrogen. For more information on the specific details of how SCR works, please contact your local Peterbilt dealer. DEF SYSTEM SCHEMATIC On most Peterbilt chassis the DEF Supply Module (or pump) is integrated into the DEF tank. Peterbilt does not allow relocation of this pump. The following schematic details how the DEF lines route to the after-treatment system.

FIGURE 9-1. DEF System Schematic

9 AFTERTREATMENT

Peterbilt Motors Company 9-2

DEF will freeze at approximately 11 F. In order to keep DEF from freezing all tanks will be heated with engine coolant. The following schematic shows the routing of these lines. It is critical that the system is not compromised in any manner. Below, numbers denote the order of the component in the flow.

FIGURE 9-2. DEF Coolant Routing Schematic

GENERAL GUIDELINES FOR DEF SYSTEM The installation of the DEF tank is a critical component of the aftertreatment system. While Peterbilt does not recommend relocating the DEF tank, there are applications and body installations that will require it. The guidelines below must be strictly followed by any entity relocating the tank. Failure to follow the guidelines completely and accurately may result in engine shut-down situations.

PACCAR-approved DEF hoses are required when retrofitting for system to function properly. The use of unapproved hoses for DEF lines will void warranty and may cause engine shut-down situations. The DEF pump (or Supply Module) cannot be relocated from the DEF tank.

Peterbilt offers a variety of DEF tank sizes to meet every application. The DEF tank volume is regulated by the E.P.A. Peterbilt advises against modifying the tank volume after the truck has been delivered from the factory. These are estimated nominal (published) maximum fuel capacities for various DEF tanks, engines, and fill ratios. Dosing rates for these calculations are also shown.

INSTALLATION REQUIREMENTS AND DIMENSIONS FOR DEF SYSTEM When relocating any DEF system components, the locations must meet the guidelines below. Failure to comply may result in non-conformance to EPA standards and engine shutdown. With all relocating procedures, general clearances and routing guidelines must be followed. See section 10 of this manual for general routing guidelines. When relocating the components the maximum pressure DEF hose length, from Supply module to Dosing Module, is 5.5 meters (216.5"). Maintain a minimum of 3" clearance to shielded exhaust components when routing DEF lines to prevent possible melting. If the DEF tank is relocated the coolant lines will need to be modified. During this process if the tank is moved forward on the chassis (closer to the engine) it is necessary to remove excess coolant lines and maintain the original routing path. If the tank is moved rearward on the chassis the additional length of cooling line required to complete the installation must be installed in a straight section of the existing coolant routing lines. This process minimizes the change in coolant flow by mitigating changes in restrictions. Changes in restriction are added with excessive line length and bends. Work with your local Peterbilt dealer if you are unsure about the coolant line modifications. ROUTING TO THE DOSING MODULE (INJECTOR) A DEF pressure line trap is no longer required after EPA 2013 emissions level engine. The dosing module (injector) no longer needs to be purged and relative heights of components are no longer critical. See Figure 9.3 below for typical routing with RHUC exhaust and LH DEF tank shown. Also shown in this figure is the coolant line routing for 579 and 567 models.

DEF SUPPLY MODULE MOUNTING REQUIREMENTS The Supply Module (or Pump) standard mounting location is on the DEF tank assembly. Body builders may need to relocate this component, and should follow the location and length restrictions above. Additionally the mounting and the orientation of the Supply Module must not exceed 45 from vertical in any direction.

FIGURE 9-4. Supply Module Allowed Clocking Angle Limit Scribes a 90 Inverted Cone.

SECTION 10 ROUTING INTRODUCTION This section specifies the general requirements for securing hoses and electrical wires to present an orderly appearance, facilitate inspection and maintenance, and prevent potential damage to these lines. DEFINITIONS Bundle: Two or more air, electrical, fuel, or other lines tied together to form a unitized assembly. Clamp: A cushioned rigid or semi-rigid, anti-chafing device for containing the bundle and securing it to the frame or other structural support. Standard clamps have a black elastomer lining. High temperature clamps (e.g., those used with com- pressor discharge hose) have a white or red elastomer lining (most applications for these are called out in the bills of material). An assembly of two clamps fastened together to separate components is referred to as a butterfly clamp. Note: the metal portion of clamps shall be stainless steel or otherwise made capable, through plating or other means, of passing a 200 hour salt spray test per ASTM B117 without rusting.

FIGURE 10-1. Clamp and Butterfly Clamp

Butterfly Tie: A tough plastic (nylon or equivalent) locking dual clamp tie strap used to separate bundles or single lines, hoses, etc. These straps must be UV stable. (Tyton DCT11)

FIGURE 10-2. Butterfly Tie

Tie Strap: A tough plastic (nylon, or equivalent) locking strap used to tie the lines in a bundle together between clamps or to otherwise secure hoses and wires as noted below. These straps must be UV stable.

FIGURE 10-3. Tie Strap

Heavy Duty (HD) Mount: A black rigid device used for securing a tie strap to the frame or other structural support. Mounts are made of impact modified, heat stabilized UV resistant nylon capable of continuous operation between temperatures 220F (150) and -40F (-40).

FIGURE 10-4. Heavy Duty (HD) Mount.

NOTE: Heavy duty tie straps 0.50in (12.7mm) wide (Tyton T255ROHIR or similar) shall be used whenever HD

mounts are specified, although 0.25in (6.4mm) tie straps may be used in some specified applications. Excess of material: More than 3 inches of slack for every 14 inch section of hose routing, except for air conditioner hoses. Shortness of material: Less than 1 inch of slack on a 14 inch section of hose routing. ROUTING REQUIREMENTS Electrical Wiring

Electrical ground wire terminals must be securely attached and the complete terminal surface must contact a

clean bare metal surface. See R414-558 for grounding wire connection practice. Apply electrical contact corrosion

inhibitor Nyogel 759G grease (made by William F. Nye, Inc., New Bedford, MA) per R414-558.

Dont bend wires or use tie straps within 3 inches (75 mm) of (connected) wire connectors or plugs.

Electrical wiring must be routed so that other components do not interfere with it

Electrical wiring must be routed away from moving components so that at least 13.0 mm (0.5 in.) of clearance

exists when the component is in operation and at maximum limits of the components travel

Electrical wiring must be protected in the locations they are routed

Electrical wiring must be routed to avoid heat sources

Electrical wiring must be secured to a crossmember when going from one frame rail to the other

When crossing other components, electrical wiring must have a covering of convoluted tubing, PSA tape, or must

be separated from the component with a standoff or butterfly clamp

Electrical wiring must not be routed directly over a sharp edge unless separated from the edge by a clip, standoff

bracket, or similar spacing feature that prevents any risk of chafing or cutting

o Alternatively, the installation of windlace applied to the edge along with PSA tape or convoluted tubing on

the harness is acceptable

Electrical wiring must be routed in a way that will not place strain on connectors.

10 Routing

Peterbilt Motors Company 10-3

Wires in Bundles Electrical wires (other than the exceptions covered below) running parallel with air or coolant hose bundles, may be included in the bundle if they are isolated from the hoses with a covering of convoluted plastic tubing. Exceptions:

Battery cables (including jump start cables) may be bundled with or tied to the charging wire harness. They shall not be bundled with or tied directly to any other components, including hoses, wires, or bundles. They shall be separated from other routed components using butterfly ties at intervals not exceeding 14 inches (356 mm). Battery strap (W84-1000) tie down shall be used without exception to secure battery cables to frame mounted or other major component (e.g. engine, transmission, etc.) mounted standoffs at intervals not exceeding 14 inches (356 mm). The (positive) battery cable shall be covered with convoluted plastic tubing from terminal to terminal.

110/220 volt wires for engine heaters, oil pan heaters, transmission oil heaters and battery pad warmers, shall not be included in any hose/wire bundle with a fuel hose. Individual heater wires not in a bundle shall be separated from other components by using butterfly clamps or butterfly ties at intervals not exceeding 14 inches (356 mm). Heater wires with a secondary covering shall be covered with convoluted tubing whether they are in bundles or not.

Wires Crossing Other Components Electrical wires crossing over other components, such as lines, bolt heads, fittings, engine components lifting eyes, engine block, cylinder head, etc., close enough to rub shall be isolated with a covering of convoluted tubing and separated from the component by using butterfly clamps, butterfly ties, or plastic sheathing. 110/220 volt engine heater wiring shall be installed with butterfly ties or butterfly clamps Piping Use no street elbows in air brake, water, fuel, or hydraulic systems unless specified on the piping diagram and the build instructions. Use no elbows in the air brake system unless specified on the air piping diagram and the build instructions. Hoses Crossing Components Hoses crossing over other components close enough to rub shall be protected with a secured covering of convoluted plastic tubing (part number K344-813), another section of hose, or plastic sheathing (part number K213-1312). The usage of butterfly ties, or butterfly clamps are also recommended. Air Compressor Discharge Hoses Wires or hoses shall not be tied to the high temperature air compressor discharge hose. Hoses and wires may be routed across the air compressor discharge hose at a distance of 18 inches (457 mm) or greater from the compressor discharge port. In this case the crossing hoses and wires shall be butterfly clamped to the air compressor discharge hose and covered with convoluted tubing at the clamp point (use high temperature clamps on the compressor hose). Bundles HD mount and tie strap, or clamp shall be located at intervals not to exceed 14 inches (356 mm) along the bundle. Regular tie straps shall be located at intervals not to exceed 7 inches (178 mm) between HD mount or clamps. Extra tie straps may be used as needed to contain the hoses and wires in the bundle. Routing of Wires and Hoses near Moving Components Wires and Hoses shall be routed away from moving components, such as fans, shackle links, drivelines, steering linkages, etc. so that there is at least 0.5 inches (12.7 mm) clearance when the component is operating at its maximum travel limits. A minimum clearance of 1.0 inches (25.4) shall be maintained between steering axle tires (and associated rotating parts) in all positions and routed components, such as hoses, oil lines, wires, pipes, etc.
