Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. Ensure that the sensor face is clear of contamination that could effect the performance of the sensor.

Mechanical Electrical
- Fuses Central junction box (CJB) - fuse 6P,
Central junction box (CJB) - G
Maxi fuse 62
- Sensor condition and - Wiring harness
installation - Electrical connector(s)
- Sounder(s) - Sensor(s)
- Switch - Parking aid switch
- Parking aid module

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.
6. Use the manufacturer approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the self-test or 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
