Repair Instructions

Step 1: Clean the Camera Lens

Step 2: Inspect and Repair Connections

  1. Access the Camera Wiring:

    • Plug the OBD-II scanner into the vehicle’s diagnostic port (usually located under the dashboard).

  2. Scan for Codes:

There could be underlying issues related to the infotainment system or more complex electronic faults that require specialized equipment.
