Control modules in the MOST network

MOST network





The MOST network can consist of up to eight 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.
When the vehicle is equipped with the Subwoofer module (SUB), the Infotainment control module (ICM) as well as the Audio module (AUD) are also included as standard on the MOST network.
The simplest variation is when the vehicle is only equipped with an Integrated Audio Module (IAM) and an Infotainment control module (ICM).

The table below lists all the control modules which may be included in the MOST network for the C70.

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 = Factory installed accessories, during the purchase of a new car. Accessory = After market installation.
(x) = Position number in the illustration.
