SAFETY AND COMPLIANCE
FEDERAL MOTOR VEHICLE SAFETY STANDARDS AND 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 Stag e 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 2–1.
In addition, affixed to the driver’s side door frame or edge is an Incomplete Vehicle Certificati on la bel. See Figure 2–2.
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 complianc e wit h the particu lar
regulations upon completion of the modifications.

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 Sta ge Manufacturer” and certifies that the
vehicle complies with Federal Motor Vehicle Safety Standards. (See Figure 2–2.) 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).”
Peterbilt Motors Company 2-2

SAFETY AND COMPLIANCE
However, if the vehicle cannot be completed and certified with in 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 manufactures 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 changes to the new certification regulation. Please refer to the Feb 15, 2005 final
rule for all of the details related to this regulation. You can contact NTEA Technical Services Department at 1-800-441NTEA for a copy of the final rule (DocID 101760).

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 Regul ati ons a nd California Air Resources
Board (CARB). These emissions control c omponents/ systems may only be replaced with origin al
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 s ha pe and aer odynamic 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
• 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 variances from the
relocation requirements may cause the emissions control components/systems to operate improperly potentially resulting
in engine de-rate.

SAFETY AND COMPLIANCE
NOTE
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.
All 2017 engine emissions certified vehicles will be equipped with an On-Board
Diagnostics (OBD) system. The OBD system is desig ned to d etect m alfunctions of any
engine or vehicle component that may increase exhaust em issions 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 sys tem consists of computer program on o ne or more of t he vehicle’s 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.
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
COMPRESSED AIR SYSTEM

• 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
• NO
• PM Sensor

SAFETY AND COMPLIANCE
• 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 owner’s manual for appropriate winter front usage
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 overspeed shutdown devices must not introduce restriction in the intake system
• All plumbing associated with the charge air cooler may not be modified

SAFETY AND COMPLIANCE
ELECTRICAL SYSTEM
The following are highlights of some of the more common or critical aspects of this system.
• Electr ic al harnes ses 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 manufacture’s
guidelines. This includes alternator ground voltage drop and alternator ground cable effectiveness.
See the engine manufacture’s 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 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.
