Solution

1. Preparation

Gather tools: socket set, trim removal tools, multimeter, cleaning supplies (isopropyl alcohol, microfiber cloth).
Ensure the vehicle is parked on a flat surface and turn off the engine.

2. Clean the Camera Lens

Use a microfiber cloth and isopropyl alcohol to gently clean the camera lens.
Inspect for any physical damage; if damaged, replacement is necessary.

3. Check and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse for the rear view camera (refer to the owner's manual).
Use a fuse puller to remove the fuse and check it for continuity with a multimeter.
If blown, replace with the same amperage fuse.

4. Inspect Wiring Connections

Remove the trim panel covering the rear camera area using trim removal tools.
Locate the wiring harness connected to the rear camera.
Ensure all connections are secure and free of corrosion. Reconnect if loose or damaged.

5. Test the Camera Functionality

Reconnect the battery if it was disconnected.
Start the vehicle and engage reverse to test the rear view camera.
If the camera is still non-functional, it may require replacement.

6. Replace the Camera (if necessary)

Disconnect the wiring harness from the camera.
Remove the camera from its housing (may require unbolting).
Install the new camera in the reverse order, ensuring all connections are secure.
