Solution

1. Preparation

Gather tools: Screwdriver set, multimeter, OBD-II scanner, cleaning cloth.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Clean the Camera

Locate the rear view camera mounted on the liftgate.
Use a cleaning cloth to gently wipe the camera lens and remove any dirt or obstructions.
Check for any signs of physical damage to the camera housing.

3. Check and Replace Fuses

Open the fuse box located under the dashboard or in the engine compartment.
Refer to the owner's manual for the specific fuse associated with the rear view camera.
Use a multimeter to check the continuity of the fuse; replace it if blown with a fuse of the same amperage.

4. Inspect Wiring and Connectors

Remove the trim panel around the liftgate to access the camera wiring harness.
Inspect the wiring for any signs of wear, fraying, or corrosion.
Ensure all connectors are securely attached. If any are loose, reconnect them firmly.

5. Test the Camera System

Reconnect the negative battery terminal.
Start the vehicle and shift into reverse to check if the rear view camera activates.
If necessary, run a diagnostic scan again to see if any new error codes appear.
