Mute Signal Circuit between Stereo Component Amplifier and Telematics Transceiver |
DESCRIPTION
The DCM (telematics transceiver) sends a mute signal to the stereo component amplifier assembly.
The stereo component amplifier assembly controls the volume according to the mute signal from the DCM (telematics transceiver).

CAUTION / NOTICE / HINT
NOTICE:
- When replacing the DCM (telematics transceiver), make sure to replace it with a new one.
-
Before replacing the DCM (telematics transceiver), refer to Registration.
