Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle battery to prevent any electrical shorts.
Ensure the vehicle is in a safe and stable position.

2. Clean the Camera Lens

Use a microfiber cloth and a gentle cleaner to wipe the camera lens.
Check for obstructions like dirt or water that may affect visibility.

3. Inspect and Repair Wiring

Remove any panels blocking access to the rearview camera wiring.
Inspect wiring for frays, breaks, or loose connections.
Repair or replace damaged wiring as necessary, ensuring all connections are secure.

4. Test Camera Voltage

Reconnect the vehicle battery.
Use a multimeter to check for voltage at the camera connector.
- Expected voltage: approximately 12 volts.
If no voltage is detected, trace wiring back to the source and fix any breaks.

5. Replace the Camera (if necessary)
