Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean the Camera Lens

Use a soft cloth and a gentle cleaning solution to clean the camera lens.
Ensure no moisture is trapped behind the lens.

3. Inspect the Camera Connection

Locate the rearview camera harness, usually near the rear bumper.
Disconnect the camera connector and inspect the pins for corrosion or damage.
Reconnect the harness securely.

4. Test the Voltage Supply

Reconnect the negative battery terminal.
Use a multimeter to check the voltage at the camera harness connector.
- Expected voltage: 6-12 volts when the vehicle is in reverse.
If voltage is not present, trace back to the wiring or check fuses.
