Component Locations (Part 1)
The MOST network can consist of up to nine different control modules.
The infotainment control module (ICM) deals with monitoring and communication on the MOST network. The infotainment control module (ICM) is in
turn monitored by the central electronic module (CEM) on the CAN network.
The vehicle can be equipped with either a media player module (MPM) or an integrated audio module (IAM).
When the vehicle is equipped with a media player module (MPM), there are - in addition to the infotainment control module (ICM) - three control
modules fitted as standard on the MOST network. These are the audio module (AUD), AM/FM tuner module (AFM) and media player module (MPM).
When the vehicle is equipped with an integrated audio module (IAM), only this, besides the infotainment control module (ICM), is fitted as standard on
the MOST network.
The table below lists all the control modules which may be included in the MOST network.
Explanation:
CAN = Controller Area Network, electrical network for communication.
LS CAN = low speed side of the CAN.
MOST = Media Oriented Systems Transport, fiber optic network for communication.
Master control module = Control module which monitors the MOST network.
Slave control module = Control module which supplies the MOST network functions.
Option = accessory installed at the factory during the purchase of a new car.
Accessory = after market installation.
(x) = position number in the illustration.
