Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the vehicle battery to prevent electrical shorts.

2. Clean the Camera Lens

Use a microfiber cloth and appropriate lens cleaner.
Wipe the camera lens gently to remove any dirt or smudges.
Reconnect the battery and test the camera functionality.

3. Inspect and Repair Wiring

Remove the rear bumper cover if necessary for access to the wiring harness.
Inspect the wiring for any frays, breaks, or corrosion.
Repair or replace any damaged wiring using appropriate wire connectors and electrical tape.

4. Test and Replace the Camera

If the camera is still not functional, unplug the camera connector and test it with a multimeter for voltage.
If no voltage is detected, trace the wiring back to the control module for potential issues.
If voltage is present but the camera still does not work, replace the rearview camera with a new unit.

5. Reassemble and Test

Reinstall any removed components, such as the bumper cover, ensuring all fasteners are tightened to manufacturer specifications.
Reconnect the vehicle battery.
Start the vehicle and shift into reverse to test the camera functionality.
