Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during electrical work.

2. Inspect and Clean the Camera

Locate the rearview camera, typically mounted above the license plate area.
Clean the lens using a soft cloth and appropriate cleaner to remove any obstructions.
Inspect the camera housing for physical damage or wear.

3. Check Electrical Connections

Access the rearview camera wiring harness located behind the bumper.
Disconnect the harness and inspect for corrosion or damage; repair any issues found.
Reconnect the harness securely.

4. Test Power Supply

Using a multimeter, set it to measure DC voltage.
Connect the multimeter probes to the camera connector terminals.
Turn the ignition on (do not start the engine) and check for a voltage reading of approximately 12V.
If voltage is absent, trace back the wiring to locate the break or fault.

5. Replace Camera if Necessary

If the camera is found to be faulty, remove it by unscrewing the mounting screws.
Disconnect the camera from the wiring harness.
Install the new camera by reversing the removal steps and ensuring secure connections.

6. Reassemble and Test

Reconnect the vehicle's battery.
Start the vehicle and put it in reverse to test the functionality of the rearview camera.
Verify that the image displays correctly on the infotainment screen.
