Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, cleaning supplies (microfiber cloth, water), basic hand tools (screwdriver set, socket set).
Disconnect the vehicle battery before working on electrical systems.

2. Clean the Camera Lens

Use a microfiber cloth and a mixture of water and mild soap to clean the camera lens.
Rinse with clean water and dry with a soft cloth to ensure no residue remains.

3. Inspect and Repair Wiring

Remove any panels or covers obstructing access to the camera wiring.
Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
If damaged, splice in new wiring or replace the harness as necessary.

4. Test Camera Voltage

Reconnect the battery and set the vehicle to reverse.
Use a multimeter to test the voltage at the camera connector; it should read approximately 12 volts.
If there is no voltage, trace the wiring back to the reverse light circuit or the infotainment system to locate the fault.

5. Replace Camera (if necessary)

If the camera is found to be faulty, remove the camera assembly by unscrewing it from its mount.
Disconnect the wiring harness and install the new camera by reversing the removal steps.
Secure the camera and reconnect the wiring.
