Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface with the engine off.

2. Inspect and Clean Camera

Locate the rearview camera, typically mounted above the license plate.
Remove any dirt or debris from the camera lens using a soft cloth.
If the lens is damaged, proceed to replace the camera.

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Using a fuse puller, check the fuse for the rearview camera; replace it if blown.
Ensure the replacement fuse matches the amperage specified in the owner's manual.

4. Test and Repair Wiring

Reconnect the negative battery terminal.
With the vehicle in reverse, inspect the wiring harness connecting the rearview camera to the multimedia unit.
Look for any frayed wires or loose connections and repair as necessary.

5. Replace Camera (if necessary)
