Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Clean the Camera

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

3. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse for the rearview camera (refer to the owner's manual).
If blown, replace with a fuse of the same amperage.

4. Inspect Wiring and Connections

Remove the trim panel covering the rearview camera.
Check the wiring harness for frays, breaks, or corrosion.
Disconnect the camera connector and inspect for bent pins or corrosion; clean if necessary.

5. Test Camera Voltage

With the multimeter, set it to the DC voltage setting.
Connect the probes to the camera connector terminals while someone shifts the vehicle into reverse.
Confirm that voltage is present (typically around 12V); if no voltage, trace wiring back to the source.

6. Replace Camera (if necessary)

If the camera is not receiving power or is physically damaged, remove it by unscrewing any mounting hardware.
Disconnect the wiring harness from the old camera and connect it to the new camera.
Secure the new camera in place and reassemble any panels removed.
