Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clean Camera Lens

Remove any debris or dirt from the camera lens using a soft cloth and mild cleaning solution.
Check for physical damage; if the lens is cracked, proceed to replace the camera.

3. Check Electrical Connections

Locate the rearview camera wiring harness, usually near the rear tailgate area.
Disconnect the wiring harness and visually inspect for corrosion or damage.
Clean the connectors with electrical contact cleaner and reconnect securely.

4. Test Power Supply

Connect the multimeter to the camera connector.
Set the multimeter to measure DC voltage.
Have an assistant shift the vehicle into reverse while you check for voltage at the camera connector. You should see voltage (typically around 12V).
If no voltage is detected, trace the wiring back to the source to identify any breaks or faults.

5. Replace Rearview Camera (if necessary)

If the camera is defective, remove it by unscrewing any retaining screws.
Disconnect the wiring harness from the old camera.
Connect the new rearview camera to the wiring harness.
Secure the new camera in place with screws.

6. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the vehicle, engage reverse gear, and check the rearview camera's functionality.
