Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to avoid electrical shorts.
Tools Required: Screwdriver set, multimeter, OBD-II scanner, trim removal tool.

2. Inspect and Clean the Camera

Remove any debris or dirt from the rearview camera lens using a soft microfiber cloth.
If the lens is cracked or damaged, proceed to replace the camera.

3. Check and Repair Wiring

Inspect the wiring harness leading to the rearview camera for frayed wires or loose connections.
If any wires are damaged, use electrical tape to secure them or replace the wiring harness if necessary.
Ensure all connectors are firmly attached; reseat any loose connections.

4. Test Camera Power Supply

Reconnect the negative battery terminal.
Use a multimeter to test the voltage at the camera connector; it should read approximately 12V when the vehicle is in reverse.
If voltage is not present, trace back to the fuse and check the appropriate fuse for the camera system.

5. Replace Camera (if necessary)

If the camera is defective, remove it from the mounting bracket by unscrewing it.
Disconnect the camera's wiring harness.
Install the new camera by connecting the wiring harness and securing it with screws.

6. Reassemble and Test

Reinstall any trim pieces that were removed during inspection.
Reconnect the negative battery terminal.
Test the camera by placing the vehicle in reverse and checking the display for functionality.
