Solution

1. Preparation

Gather tools including a multimeter, OBD-II scanner, and a cleaning cloth.
Ensure the vehicle is parked safely and the engine is off.

2. Clean the Camera Lens

Use a soft, lint-free cloth to gently clean the camera lens.
Ensure no dirt, dust, or debris is obstructing the view.

3. Check Wiring and Connections

Remove the rear bumper cover as necessary to access the camera wiring.
Inspect the wiring harness for frayed or damaged wires.
Ensure all connectors are securely connected to the camera and the vehicle's electrical system.

4. Test Camera Power Supply

Set the multimeter to measure DC voltage.
With the vehicle in reverse, probe the camera's power connector to ensure it receives approximately 12V.
If no voltage is present, trace the wiring back to the vehicle's electrical system for issues.

5. Inspect Infotainment System

Turn on the vehicle and access the infotainment system.
Navigate to the camera settings and ensure the backup camera is enabled.
If necessary, perform a system reset to clear any temporary software glitches.

6. Replace Camera (if necessary)

If the camera is still not functioning after inspection, it may need to be replaced.
Remove the defective camera following the manufacturer's service manual.
Install the new camera, ensuring all connections are secure and properly routed.
