Inspect the connectors for corrosion or damage; clean and reconnect if necessary.
Ensure that the wiring harness is securely connected to both the camera and the vehicle’s electrical system.

4. Test and Replace Camera Module (if necessary)

If the camera still does not work, test the camera module for functionality.
Tools Required: Multimeter, replacement backup camera module (if needed).
Disconnect the camera from the harness and measure the voltage at the connector.
If no voltage is present, trace back to the wiring and connectors.
