Disconnect the camera connector carefully.
Inspect the pins for corrosion or damage; clean with electrical contact cleaner if necessary.
Reconnect the connector firmly, ensuring it clicks into place.

4. Test Reverse Light Switch

Locate the reverse light switch, typically found on the transmission.
Use a multimeter to test for continuity when the vehicle is in reverse.
If the switch is faulty, replace it with a new component.

5. Camera Replacement (if necessary)

If the above steps do not resolve the issue, consider replacing the camera.
Remove the camera housing from the rear liftgate (use a trim removal tool).
Disconnect the camera wiring harness and remove the camera from its housing.
Install the new camera in reverse order, ensuring all connections are secure.
