Reconnect the negative battery terminal.
Access the rearview camera harness located at the rear of the vehicle.
Inspect for loose, corroded, or damaged connections, and repair or replace as necessary.
Ensure that the wiring harness is properly secured and not pinched or frayed.

5. Test Infotainment System
