Mute Signal Circuit (From Radio and Navigation Assy)

MUTE SIGNAL CIRCUIT (FROM RADIO AND NAVIGATION ASSEMBLY)

CIRCUIT DESCRIPTION

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

The RMUT 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 stereo component controller assembly is normal, no sound or only an extremely small sound can be produced.
