Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use the fuse diagram to identify the fuse associated with the rearview camera.
Remove the fuse using a fuse puller or pliers and inspect it for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage rating.

3. Check Wiring and Connections

Remove the rear trim panel to access the rearview camera wiring.
Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
Disconnect and reconnect the wiring harness to ensure a secure connection.
If any wires are damaged, repair or replace them as necessary.

4. Clean the Camera Lens

Use a cleaning cloth and mild soap solution to gently clean the camera lens.
Ensure that the lens is free from any obstructions or debris that may affect visibility.

5. Test the Camera System

Reconnect the battery if it was disconnected.
Start the vehicle and shift into reverse to check if the rearview camera activates.
If the camera is still not functioning, further inspection of the camera unit or infotainment system may be required.
