Communications Control Module: Description and Operation
Media Player Module (MPM)
Media player module (MPM)
The media player module (MPM) players play back MiniDiscs and CDs. There are three versions of the media player module (MPM):
combined CD/MD player.
Only one media player module (MPM) can be installed in the car.
The media player module (MPM) is located in the center console.
The media player module (MPM) uses optical serial communication to communicate with other components on the MOST network. This means that all
communication with the media player module (MPM) is via the infotainment control module (ICM). The media player module (MPM) communicates
with the audio module (AUD) for access to the loudspeakers.
Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using VIDA via the data link connector
(DLC) in the car.
For further information, also see Signal specifications.
The table below summarizes the input signals to and output signals from the media player (MPM). These signals type are only transmitted via MOST
communication. The illustration below displays the same information with the Volvo component designations.
