1 Safety Information
WARNING –This warning symbol identifies special instruction or procedures,
which if not correctly followed could result in personal injury, or
loss of life.
Read and observe all Warning and Caution hazard alert messages in this publication. They provide infor-
mation that can help prevent serious personal injury, damage to components, or both.
WARNING –To prevent serious eye injury, always wear safe eye protection
when you perform vehicle maintenance or service.
WARNING –Park the vehicle on a level surface. Block the wheels to prevent the
vehicle from moving. Support the vehicle with safety stands. Do not
work under a vehicle supported only by jacks. Jacks can slip and
fall over. Serious personal injury and damage to components can
result.
WARNING –Release all air from the air systems before you remove any compo-
nents. Pressurized air can cause serious personal injury. Refer to
the vehicle manufacturer’s service manual for instructions.
WARNING –Verify and diagnose all active faults in the system prior to re-
placing OnGuard™ components. When diagnosing OnGuard™,
TOOLBOX™ Software (11.0 or higher) must be used. Be aware that
diagnostic devices must be connected prior to keying on the unit to
minimize possible OnGuard™ faults during diagnosis.

4 OnGuard™ Collision Mitigation System (CMS) Kit
This technical bulletin provides procedures for installing parts included in the OnGuard™ Collision Mitiga-
tion system kit.
The following parts are included in the kit.
Radar Sensor
Radar Bracket
OnGuard™ Display
Fascia
Radar Harness
Engine and Cab Harness
Pressure Sensor
Pressure Sensor Engine and Cab Harness
1939 Jumper Harness (for Cummins engine only)
1/2” Flange Bolts
Radar and Fascia M6 Nuts
NOTE: Make sure to verify the correct kit part number is being installed on the vehicle as all CMS radars
look alike.
5 Installation Procedures
5.1 OnGuard™ Radar Installation
1. Check the parts in the kit against the parts list and make sure the kit is complete.
2. Wear safe eye protection. Park the vehicle on a level surface.Apply the parking brake. Ensure the
ignition is turned OFF.

Installation Procedures
3. Check the bumper type to determine the correct location for mounting the radar to the bracket. For
trucks with an aerodynamic/Aerodyne bumper “A”, position the radar to the upper mounting holes
marked “A” as shown (Figure 1 and Figure 2). For trucks with a Hendrickson bumper “B”, position the
radar to the lower mounting holes marked “B” as shown (Figure 3 and Figure 4).

4. Assemble the radar to the mounting bracket using the 3 M6 flanged nuts and tighten to
61-75 in-lbs (6.9-8.4 N m).
5. Remove the bumper according to the vehicle manufacturer’s recommended instructions.
6. Place the radar bracket assembly in mounting position on the cross member just below the hood
mount pivot. Install the two ½-13 flanged bolts provided in the kit (Figure 5) and tighten to
80-110 ft-lb (108-150 Nm).

7. If necessary, modify the air dam baffle to clear the radar bracket. If a center flap is present, cut it back
to the cross member so it is flush (Figure 6). After modification, ensure the radar bracket does not
bind on any part of air dam when installed.

Installation Procedures
5.2 OnGuard™ Radar Harness Installation
The radar harness will route as follows (Figure 7).
A. From the radar across the truck’s front closing cross member to the driver’s side frame rail
B. Around the radiator back into the frame rail.
C. Past the engine with the existing wiring and electrical harness to the front firewall.
D. Up out of the frame rail, up to the fire wall and up to the Cab electrical bulk head connector.
NOTE: The following schematic shows the harness layout.
End A. Radar plug at the front center of the bumper.
End B. The end of line resistor location on the left hand forward frame rail.
End C. The cab bulk head connection on the left hand firewall inside.

2. Route the harness across the front closing cross member to outside the driver’s side frame rail
(Figure 9). When routing the harness through the frame rail, ensure the J1939 end-of-line resistor
connector is accessible near the front of the frame rail.

3. Continue routing the harness along with the headlight electrical harness back through the left hand
frame rail access hole, just past the radiator.
4. Route the harness down the inside of the frame rail to the front of the firewall, then up to the cab side
bulk head connector.
5. Disconnect the harness from the cab bulk head connector.
6. Remove the pin locking clip from the harness. Refer to the factory harness installation information.
NOTE: If you have extra length of harness, bundle it up in this area and tie it down to the main bundle
(Figure 10).

7. Install the following radar harness wires into the backside of the cab bulk head harness connector
(Figure 11 and Figure 12): Wire 444 to pin 9, wire GND to pin 42, yellow wire (J1939-) to pin 10 and
green wire (J1939+) to pin 11. Reinstall the locking pin clip on the harness.
