If there is an open in the circuit, the audio system cannot be operated using the steering pad switch assembly. If there is a short in the circuit, the same condition as when a switch is continuously depressed occurs. Therefore, the navigation receiver assembly cannot be operated using the steering pad switch assembly, and also the navigation receiver assembly itself cannot function.
