Steering Pad Switch Circuit: Description
This circuit sends an operation signal from the steering pad switch assembly to the navigation ECU sub-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 ECU sub-assembly cannot be operated using the steering pad switch assembly, and also the navigation ECU sub-assembly itself cannot function.
