DESCRIPTION
This circuit sends an operation signal from the steering pad switch assembly to the navigation receiver assembly.
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.
