Is there continuity between any of the terminals?
YES - Repair short in the appropriate wire(s) between the navigation unit and the rearview camera.
NO - Go to step 11.
11. Check for continuity between navigation Unit connector D (7P) and rearview camera 6P connector as shown.
Is there continuity?
YES - Go to step 12.
NO - Repair open in the appropriate wire(s) between the navigation unit and the rearview camera.
12. Check for continuity between the navigation connector D (7P) terminal No. 7 and body ground.
