Sensor 8 Failure

SENSOR 8 FAILURE

For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

With rear sensors active.

- Set Condition:

A Sensor Settling Time failure or a Sensor Verify failure is detected.





Diagnostic Test

1. DTC IS ACTIVE

NOTE: Make sure that the rear bumper is free of dirt and debris to keep the system operating properly.

NOTE: Jackhammers, large trucks, and other vibrations could affect the performance of the system.

With the scan tool Erase DTCs.

Cycle the ignition off for at least 1 minute.

Move an object into range of the Sensor that set this DTC.

Turn the ignition on.

NOTE: The system is active only when the vehicle is in reverse or neutral for vehicle speeds less than 16 km/h (10 mph). If the vehicle Parking/Emergency Brake is applied, the system is deactivated.

With the brake applied, move the gear selector to the neutral position.

With the scan tool under Inputs/Outputs, read the Sensors input state. The state must indicate "Active" for the diagnostic to run.

With the scan tool read DTCs.

Does this DTC reset?

Yes

- Go To 2

No

- Go To 3

2. PARK ASSIST SENSOR

The Park Assist Module has detected a Park Assist Sensor failure.

Replace sensor number 8.

With the scan tool Erase DTCs.

Cycle the ignition off for at least one minute.

Move an object into range of the Sensor that was replaced.

Turn the ignition on.

NOTE: The system is active only when the vehicle is in reverse or neutral for vehicle speeds less than 16 km/h (10 mph). If the vehicle Parking/Emergency Brake is applied, the system is deactivated.

With the brake applied, move the gear selector to the neutral position.

With the scan tool under Inputs/Outputs, read the Sensors input state. The state must indicate "Active" for the diagnostic to run.

With the scan tool read DTCs.

Does this DTC reset?

Yes

- Replace the Park Assist Module.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Test Complete.

3. INTERMITTENT CONDITION

The conditions necessary to set this DTC are not present at this time.

Using the wiring diagrams/schematics as a guide, inspect the wiring and connectors.

While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.

Look for the data to change or for the DTC to reset during the wiggle test.

Were any problems found?

Yes

- Repair as necessary.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
