1. Preparation

Gather necessary tools and parts.
Tools required:
- OBD-II scanner
- Multimeter
- Screwdriver set
- Trim removal tools
Safety warning: Ensure the vehicle is in park and the ignition is off before starting work.

2. Inspect and Clean Camera Lens

Locate the rear view camera, typically mounted on the tailgate or trunk lid.
Use a microfiber cloth to gently clean the camera lens to remove any dirt or residue.
Check for any physical damage to the camera housing.

3. Check Wiring and Connections

Carefully remove any trim or covers surrounding the camera and infotainment unit using trim removal tools.
Inspect the wiring harness for frayed wires or loose connectors at both the camera and infotainment unit.
Reconnect any loose connectors and secure any damaged wiring.

4. Test Camera Voltage

Disconnect the camera connector and use a multimeter to check for power at the connector when the vehicle is in reverse.
- Set the multimeter to DC voltage.
- Insert the probes into the connector pins corresponding to power and ground.
If there is no voltage, trace the wiring back to the infotainment system for further inspection.

5. Replace Camera (If Necessary)

If the camera is confirmed faulty, purchase a replacement camera compatible with the MK7.5.
Disconnect the old camera’s wiring harness and remove it from its mounting.
Install the new camera by reversing the removal process and reconnecting the wiring harness.
