Normal Operation
The audio unit receives a vehicle speed signal from the PCM through circuit 679 (GY/BK). When the vehicle speed increases, the audio unit will receive this change in signal output from the PCM and increase the volume level. When the vehicle speed decreases, the audio unit will interpret this signal change and decrease the volume level.

Possible causes
- circuit 679 (GY/BK) open
- audio unit
