AUDIO AND VISUAL SYSTEM Steering Pad Switch Circuit

DESCRIPTION

This circuit sends an operation signal from the steering pad switch assembly to the multi-media module 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 multi-media module receiver assembly cannot be operated using the steering pad switch assembly, and also the multi-media module receiver assembly itself cannot function.
