Remove any panels that cover the camera wiring harness.
Inspect the wiring for any signs of wear, corrosion, or disconnection.
Reconnect any loose connectors and repair any damaged wiring as needed.

5. Replace Camera (if necessary)

If the camera is confirmed to be faulty, remove the old camera by unscrewing it from its mount.
Disconnect the wiring harness from the old camera.
Install the new camera by connecting the wiring harness and securing it in place.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and shift into reverse to test if the backup camera displays the image correctly.
