This circuit sends an operation signal from the steering pad switch to the radio receiver.

If there is an open in the circuit, the audio system cannot be operated using the steering pad switch.

If there is a short in the circuit, the same condition as that when the switch is continuously depressed occurs.

Therefore, the radio receiver cannot be operated using the steering pad switch, and also the radio receiver itself cannot function.

This circuit is necessary for the ASL (Auto Sound Leveliser) built into the stereo component amplifier. Speed signals are received from the combination meter and used for the ASL.

The ASL function automatically adjusts the sound data in order to enable hearing the clear audio sound even when vehicle noise increases (as vehicle noise increases, the volume is turned up etc.).

HINT
