Solution

1. Preparation

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

2. Clean the Camera Lens

Use a soft cloth and appropriate lens cleaner to gently wipe the camera lens.
Inspect the cleaning process to ensure no debris remains that could obstruct the view.

3. Inspect Wiring and Connections

Remove the rear bumper cover if necessary to gain access to the camera wiring harness.
Disconnect the wiring harness from the camera and inspect for corrosion or damage.
Reconnect the harness securely ensuring a proper fit.

4. Test Power Supply

Use a multimeter to check for voltage at the camera connector.
- Set the multimeter to DC voltage mode.
- Turn the ignition to the "ON" position (do not start the engine).
- Probe the connector to ensure it receives approximately 12V.
If voltage is absent, trace the wiring back to the fuse box and check for a blown fuse or damaged wiring.

5. Software Reset

If no hardware issues are found, perform a software reset of the infotainment system.
- Disconnect the vehicle battery for at least 10 minutes to reset systems.
- Reconnect the battery and check if the camera functions correctly after rebooting.

6. Replace Camera Unit (if necessary)

If diagnostics indicate a faulty camera, remove the camera from its housing.
Install the new camera unit by reversing the removal process, ensuring all connections are secure.
Torque screws to manufacturer specifications (consult service manual for proper torque values).
