1. Remove the right rear side trim panel Interior Trim Removal / Installation - Trunk Area.

2. Disconnect the 14P connector (A) from the parking and back-up sensor control unit (B).





3. Inspect the connector and socket terminals to be sure they are all making good contact.

- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 4.

4. With the connector still disconnected, do the following input tests.

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If the input test proves OK, the control unit must be faulty; replace it.
