Tools Required: Socket set, trim removal tool, multimeter, OBD-II scanner.

2. Inspect and Clean Camera Lens

Locate the rearview camera, which is typically mounted above the license plate.
Use a soft cloth and mild cleaning solution to clean the camera lens if dirty.
Ensure there are no obstructions that could block the camera's view.

3. Check and Replace Fuse

Open the fuse box located inside the vehicle or under the hood, depending on the model.
Identify the fuse associated with the rearview camera (consult the owner's manual for the exact location).
Use a multimeter to test the fuse for continuity.
If blown, replace it with a fuse of the same amperage.

4. Inspect Wiring and Connectors

Remove any trim panels necessary to access the wiring harness for the rearview camera.
Visually inspect the wiring for any signs of wear, damage, or corrosion.
Disconnect and reconnect all connectors to ensure a firm connection. If any connectors are damaged, replace them.
