Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, cleaning supplies (microfiber cloth, isopropyl alcohol).
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean Camera Lens

Use a microfiber cloth and isopropyl alcohol to gently clean the camera lens.
Inspect for physical damage; if damaged, proceed to replace the camera.

3. Check Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the fuse associated with the rearview camera using a fuse puller.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

4. Inspect Wiring

Trace the wiring harness from the rearview camera to the vehicle's electrical system.
Look for any frayed wires, loose connections, or corrosion at the connectors.
Repair or replace any damaged wiring or connectors as necessary.

5. Test Camera Power Supply

Reconnect the negative battery terminal.
Set the multimeter to measure DC voltage and connect the positive lead to the camera power wire.
Have an assistant shift the vehicle into reverse while monitoring the voltage; it should read approximately 12V.

6. Replace Camera (if necessary)

If the camera fails the power supply test, disconnect the wiring harness from the camera.
Remove the camera mounting screws using a socket set.
Install the new camera in reverse of the removal process and reconnect the wiring harness.
