Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the vehicle's battery to avoid electrical shorts while working on the camera system.

2. Inspect and Clean the Camera

Locate the rearview camera mounted on the tailgate.
Use a soft cloth and mild cleaner to wipe the camera lens.
Check for any physical damage to the camera housing.

3. Check and Replace Fuses

Locate the fuse box; refer to the owner's manual for the specific location of the rearview camera fuse.
Use a fuse puller to remove the fuse and inspect it for continuity.
If blown, replace with an identical fuse (typically 10A or as specified in the manual).

4. Inspect Wiring and Connections

Remove the tailgate trim panel to access the camera wiring harness.
Visually inspect the harness for wear, fraying, or disconnection.
If damaged, repair or replace the wiring as needed.

5. Test the Camera

Reconnect the battery and turn on the vehicle.
Shift the vehicle into reverse and check if the camera activates.
If still not working, consider replacing the camera unit.

6. Replace the Camera (if necessary)

Disconnect the wiring harness from the camera.
Remove the camera from its mounting bracket (usually secured with screws).
Install the new camera by reversing the removal steps, ensuring it is secured properly.
Reconnect the wiring harness and test the camera again.
