Solution

1. Preparation

Gather tools and parts before beginning work.
Tools required: OBD-II scanner, multimeter, socket set, trim removal tools.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Inspect and Clean Camera Lens

Locate the rearview camera, typically mounted on the tailgate or rear bumper.
Use a soft cloth to clean the camera lens to ensure visibility is not obstructed.
If the lens is damaged, proceed to replace the camera.

Remove any trim panels covering the camera wiring harness using trim removal tools.
Inspect the connectors for signs of corrosion or damage. Clean or replace as necessary.
Ensure all connections are securely plugged in.

4. Test Electrical Supply

Using a multimeter, check the voltage at the rearview camera connector.
Confirm that the camera receives the correct voltage (typically around 12V).
If no voltage is detected, trace the wiring back to identify any breaks or shorts.
