Collision Avoidance and Parking Assist Systems: Testing and Inspection

Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

NOTE:
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

NOTE:
Do not change sensors under warranty that have damage to the sensor face.
1 Verify the customer concern.
2 Ensure that the sensor face is clear of contamination that could effect the performance of the sensor.
3 Visually inspect for obvious signs of mechanical or electrical damage.





4 If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
5 If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

On-Board Self-test
As part of the strategy of the system, the self-test will inform the driver of any faults by a combination of the LED and tones:
- The status LED will flash if the system is active and a fault is detected in the sensors, sounders, wiring or module
- The front sounder will emit an error tone for 3 seconds if a fault is detected with the front sensors or if the rear sounder develops a fault
- The rear sounder will emit an error tone for 3 seconds if a fault is detected with the rear sensors, the switch, or the LED in the switch, or if there is a Controller Area Network (CAN) bus error
