Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean the Camera

Locate the rearview camera, typically mounted above the license plate.
Wipe the camera lens with a microfiber cloth to remove any dirt or debris.
If the lens is cracked or damaged, proceed to the next step.

3. Check and Replace Fuses

Open the fuse box and locate the fuse associated with the rearview camera.
Remove the fuse using a fuse puller and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage (refer to the owner's manual for specifications).

4. Inspect Wiring Connections

Reconnect the negative battery terminal if previously disconnected.
Remove the trim panel around the rearview camera to access the wiring harness.
Check for any damaged wires or loose connections; repair or replace as necessary.

Reconnect the vehicle's battery.
Start the vehicle and shift into reverse to check if the rearview camera activates.
Verify that the image is clear and that no error messages appear on the infotainment screen.
