Mute Signal Circuit (From Stereo Component Controller Assy)

MUTE SIGNAL CIRCUIT (FROM STEREO COMPONENT CONTROLLER ASSEMBLY)

CIRCUIT DESCRIPTION

The radio and navigation assembly controls the volume according to the MUTE signal from the stereo component controller assembly.

The MUTE signal is sent to reduce noise and a popping sound when switching the mode, etc.

If there is an open in the circuit, noise can be heard from the speakers when changing the sound source.

If there is a short in the circuit, even though the radio and navigation assembly is normal, no sound or only an extremely small sound can be produced.
