Solution

1. Preparation

Gather tools and parts needed: OBD-II scanner, multimeter, socket set, screwdriver, cleaning supplies (glass cleaner, microfiber cloth).
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Check the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the fuse related to the rear view camera (refer to the owner’s manual for the exact fuse number).
Inspect the fuse for continuity; replace it if blown (use a fuse of the same amperage).

3. Inspect the Camera and Wiring

Remove any dirt or debris from the rear view camera lens using the cleaning supplies.
Safely remove the trim around the camera if necessary to access the wiring.
Visually inspect all wiring connections for frays or breaks. If any damages are found, repair or replace the wiring as needed.

4. Test the Camera Module

Reconnect any wiring that was disconnected for inspection.
Use a multimeter to check for voltage at the camera connector while the vehicle is in reverse (ensure someone is in the driver’s seat to shift into reverse).
If there is no voltage, trace the wiring back to the fuse box to identify any breaks.

5. Replace the Camera (if necessary)

If the camera is found to be faulty, disconnect the wiring harness from the camera.
Remove the mounting screws holding the camera in place.
Install the new camera by reversing the removal steps, ensuring that all connections are secure.
