16. Check for continuity between terminals of audio-navigation unit connector G (7P) according to the table.





Is there continuity between any of the terminals?
YES - There is a short in the wire(s) between the audio-navigation unit and the rearview camera. Replace the affected shielded harness. A short in the wire(s) for the rearview camera could permanently damage the audio-navigation unit. Once the short in the wire repaired, recheck the camera operation. If the camera does not work, substitute a known-good audio-navigation unit. Audio-Navigation Unit Removal/Installation (With Navigation) If the symptom goes away, replace the original audio-navigation unit.

NO - Go to step 17.






17. Reconnect the rearview camera 12P connector.

18. Substitute and connect a known-good audio-navigation unit, Audio-Navigation Unit Removal/Installation (With Navigation) and check the rearview camera image in reverse.

Is the rear view image OK?
YES - Replace the original audio-navigation unit. Audio-Navigation Unit Removal/Installation (With Navigation)
