Each audio system component connected to the AVC-LAN (communication bus) transfers switch signals using the audio visual communication local area network.

If a short to +B or short to ground occurs in the AVC-LAN, the audio system will not function normally because communication is not possible.

The No. 1 stereo jack adapter assembly sends the sound data signal or image data signal from a USB device to the multi-media module receiver assembly via this circuit.

The No. 1 stereo jack adapter assembly sends the sound signal from an external device to the multi-media module receiver assembly through this circuit.

The sound signal that has been sent is amplified by the stereo component amplifier assembly or multi-media module receiver assembly, and then is sent to the speakers.

The multi-media module receiver assembly sends the sound signal to the stereo component amplifier assembly through this circuit.

The sound signal that has been sent is amplified by the stereo component amplifier assembly, and then is sent to the speakers.

The stereo component amplifier assembly sends a sound signal to the speakers.

Power is supplied to the multi-media module receiver assembly and steering pad switch assembly illumination when the light control switch is in the tail or head position.

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.

The multi-media module receiver assembly receives a vehicle speed signal from the combination meter assembly for DVD viewing restriction while driving, parallel parking mode of the parking assist monitor system, etc.

Check that the display is not in "Screen Off" mode.

Disconnect the USB device or "iPod" from the No. 1 stereo jack adapter assembly.
