Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a cleaning cloth.
Disconnect the vehicle's 12V battery to ensure safety before working on electrical components.

2. Inspect and Clean Camera

Remove any obstructions from the camera lens, such as dirt or debris.
If the camera is dirty, clean it with a soft cloth and suitable cleaning solution.

3. Check Electrical Connections

Locate the rear view camera wiring harness, typically found under the rear trunk panel.
Disconnect the harness and inspect for corrosion, bent pins, or damaged wires.
Reconnect the harness ensuring a secure fit.

4. Test Camera Power Supply

Set the multimeter to measure DC voltage.
Locate the power wire for the rear view camera and connect the multimeter probes.
Turn the vehicle to the "On" position (do not start) and check for a voltage reading (typically around 12V). If no voltage is detected, trace the wiring back to the source.

5. Replace Camera if Necessary

If the camera is confirmed faulty, remove the existing rear view camera by unscrewing it from its mount.
Install the new camera by reversing the removal steps, ensuring it is securely fastened and connected to the wiring harness.

6. Reconnect Battery and Test

Reconnect the 12V battery and turn on the vehicle.
Shift into reverse to check if the rear view camera is functioning properly.
