Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Clean the Camera Lens

Locate the rearview camera, typically situated above the license plate.
Use a soft cloth and cleaning solution to gently clean the camera lens.
Check if the camera activates after cleaning.

3. Check and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse related to the rearview camera (refer to the owner's manual for the specific fuse).
Inspect the fuse for continuity; replace if blown (use a fuse of the same amperage).

4. Inspect and Test Wiring

Remove the trim panel covering the rearview camera and infotainment connections.
Visually inspect the wiring for any signs of damage or corrosion.
Use a multimeter to check for voltage at the camera connector while the vehicle is in reverse. Ensure the ground is secure.

5. Confirm Backup Light Functionality

Check if the backup lights illuminate when the vehicle is in reverse.
If not, inspect the backup light bulbs and wiring for faults. Replace any defective components as needed.

Reconnect all wiring and trim panels securely.
Start the vehicle and shift into reverse to check if the rearview camera activates and displays correctly.
