Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Camera

Locate the rearview camera mounted on the tailgate or near the license plate.
Clean the camera lens using a soft cloth and glass cleaner to remove dirt or debris that may obstruct the view.

3. Check and Replace Fuses

Access the vehicle's fuse box, usually located under the dashboard or in the engine compartment.
Locate the fuse associated with the rearview camera (refer to the owner’s manual for the exact fuse designation).
Use a fuse puller to remove the fuse and inspect it visually.
If blown, replace it with a new fuse of the same amperage rating.

4. Inspect Wiring Harness

Remove any trim or panels covering the camera wiring.
Visually inspect the wiring harness for signs of wear, fraying, or corrosion.
If damaged, repair or replace the wiring harness as necessary.

5. Test Camera Power Supply

Reconnect the battery and turn on the ignition.
Use a multimeter to check for voltage at the camera connector while the vehicle is in reverse.
If no voltage is present, trace the wiring back to the source to find any breaks or shorts.

6. Replace the Camera (if necessary)

If all previous checks are satisfactory but the camera is still non-functional, remove the camera from its mount.
Disconnect the wiring harness and replace with a new rearview camera.
Reinstall the new camera following the manufacturer's instructions.
