Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and cleaning supplies.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Clean Camera Lens

Locate the backup camera, usually mounted on the rear of the vehicle.
Use a soft cloth to clean the camera lens to remove dirt or debris that may obstruct the view.

Remove any panels or covers that obstruct access to the camera wiring.
Inspect the wires for any signs of wear, fraying, or disconnection.
If any issues are found, repair or replace the damaged wiring or connectors.

4. Test Power Supply

Set the multimeter to the DC voltage setting.
With the vehicle in reverse, probe the power connector for the backup camera.
Ensure there is voltage present; if not, trace the circuit back to the fuse or switch.

If the camera is determined to be faulty, disconnect the power and video connections.
Remove the camera by unscrewing any mounting hardware.
Install the new camera by reversing the removal process, ensuring it is securely mounted and connected.
