AMP MUTE SIGNAL CIRCUIT (FROM RADIO RECEIVER ASSY)
CIRCUIT DESCRIPTION
This circuit sends the signal to the stereo component amplifier to mute the noise. Because of that, the noise
produced by changing the sound source ceases.
In addition, this circuit is used to mute the sound when the navigation system performs voice guide.
If the vehicle is equipped with a navigation system, normal audio sound will cease, and only voice guidance
will be heard from the driver's side speaker when voice guides are given.
If there is an open in the circuit, noise can be heard from the speaker when changing the sound source.
If there is a short in the circuit, even though the stereo component amplifier assy is normal, no sound or only
extremely small sound can be produced.
