FEDERAL MOTOR VEHICLE SAFETY STANDARDS COMPLIANCE

As an Original Equipment Manufacturer, Peterbilt Motors Company, ensures that our products comply with all applicable U.S. or Canadian Federal Motor Vehicle Safety Standards. However, the fact that this vehicle has no fifth wheel and that a Body Builder (Intermediate or Final Stage Manufacturer) will be doing additional modifications means that the vehicle was incomplete when it left the build plant.

INCOMPLETE VEHICLE CERTIFICATION

An Incomplete Vehicle Document is shipped with the vehicle, certifying that the vehicle is not complete. See Figure 21. In addition, affixed to the drivers side door frame or edge is an Incomplete Vehicle Certification label. See Figure 22.

NOTE These documents list the U.S. or Canadian Federal Motor Vehicle Safety Standard regulations that the vehicle complied with when it left the build plant. You should be aware that if you add, modify or alter any of the components or systems covered by these regulations, it is your responsibility as the Intermediate or Final Stage Manufacturer to ensure that the complete vehicle is in compliance with the particular regulations upon completion of the modifications.

Labels - Drivers Door and Frame

As the Intermediate or Final Stage Manufacturer, you should retain the Incomplete Vehicle Document for your records. In addition, you should record and retain the manufacturer and serial number of the tires on the vehicle. Upon completion of the vehicle (installation of the body and any other modifications), you should affix your certification label to the vehicle as required by Federal law. This tag identifies you as the Intermediate or Final Stage Manufacturer and certifies that the vehicle complies with Federal Motor Vehicle Safety Standards. (See Figure 22.) Be advised that regulations affecting the intermediate and final stage manufacturer may change without notice. Ensure you are referencing the most updated copy of the regulation during the certification and documentation processes.

In part, if the final stage manufacturer can complete and certify the vehicle within the instruction in the incomplete vehicle document (IVD), the certification label would need a statement that reads, This vehicle has been completed in accordance with the prior manufacturers IVD where applicable. This vehicle conforms to all applicable Federal Motor Vehicle Safety Standards [and Bumper and Theft Prevention Standards if applicable] in effect in (month, year).

Page 11

SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-3

However, if the vehicle cannot be completed and certified within the guidance provided in the IVD, the final stage manufacturer must ensure the vehicle conforms to all applicable Federal Motor Vehicle Safety Standards (FMVSS). The final stage manufacturers certification label would need a statement that reads, This vehicle conforms to all applicable Federal Motor Vehicle Safety Standards [and Bumper and Theft Prevention Standards if applicable] in effect in (month, year).

These statements are just part of the certification regulation. Please refer to NHTSA/DOT Title 49 CFR part 567 certification for all of the details related to this regulation.

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 in section 9 of this manual need to be

followed. Any variances from the relocation requirements may cause the emissions control components/systems to operate improperly potentially resulting in engine de-rate.

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

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/SCR 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 outlined in Section 9 of this manual:

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

The after-treatment canister mounting may not be modified

Page 14

SAFETY AND COMPLIANCE

Peterbilt Motors Company 2-6

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 after-treatment canister 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 after-treatment canister, 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 guidelines 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

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 wiring

If the alternator or battery is substituted, it must meet the requirements of the engine manufacturers

guidelines. This includes alternator ground voltage drop and alternator ground cable effectiveness.

See the engine manufacturers 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,

shall 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 figure 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.

WARNING! When jump starting using a battery charger/booster, verify that the battery

charger/booster is set to the same jump start voltage and amperage specifications

as the vehicle electrical system and batteries (i.e. if the vehicle electrical system is a

12 volt system, the jump start voltage on the battery charger/booster shall be set at

no higher than a 12 volt setting). Failure to comply may cause an explosion and/or fire resulting in death, personal injury, equipment or property damage.

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 and beyond 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: Digital Display for 579/567.

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 gauges and lamps above, the emission system also depends on signals from the after-

treatment canister and NOx sensor. Wiring between these devices, the doser and engine ECM should not

be tampered with or altered in any way. De-rate information is available in the engine after-treatment system

operator manual supplement.

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

BENDIX WINGMAN FUSION RADAR CLEARANCE

Some vehicles are equipped with the Bendix Wingman Fusion bumper mounted radar.

GENERAL WIRE ROUTING

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

Whenever possible, battery cables, electrical wires, and wire harnesses should be secured by

clamps attached to rigid components (for example, the engine, frame, bracket, etc.) or secured by tie straps fastened to other restrained lines at intervals not exceeding 460mm (18 in.).

Battery cables, alternator cables, electrical wires, and wire harnesses routed on the chassis and

engine should be covered by braided loom or convoluted tubing.

At the clamping or tie points, battery cables, electrical wires, and wire harnesses should be covered

by braided loom or convoluted tubing.
