The stereo jack adapter sends an external device sound signal to the radio receiver through this circuit.

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

If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier, radio receiver, or speakers.

The radio receiver sends a sound signal to the stereo component amplifier through this circuit.

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

If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier or speakers.

The sound signal that has been amplified by the stereo component amplifier is sent to the speakers from the stereo component amplifier through this circuit.

If there is a short in this circuit, the stereo component amplifier detects it and stops output to the speakers.

Thus, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier or speakers.

Power is supplied to the radio receiver, integration control & panel 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 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.

Set "BASS", "MID", and "TREB" to the initial values and check that sound is normal.

Check the radio's automatic station search function.

Check the CD.

Make sure that the CD is an audio CD or a CD with an MP3 or WMA file, and that it is not deformed, flawed, stained, burred, or otherwise defective.

Press the CD EJECT switch of the radio receiver for 2 seconds or more and check that the CD is ejected.
