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).

-
When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:
- A communication malfunction DTC may be stored.
- The radio and display receiver assembly may not operate normally.
-
Before replacing the DCM (telematics transceiver), refer to Registration.
