LOCATION OF CONTROL MODULES ON THE MOST NETWORK
Note. The control modules on the MOST network should be positioned in a particular order. If this order is not followed, the fault-tracing of the MOST network will deteriorate.
When a control module is added to the MOST network, it should be placed in the correct order on the network to make it easier to fault-trace the control modules.
If the control modules are connected in another order, this does not effect the function of the MOST network, but fault-tracing will be more difficult.
The control modules should be placed in the following order
- Infotainment control module (ICM)
- Multimedia module (MMM)
- AM/FM tuner module (AFM)
- Traffic message channel module (TMC)
- Audio module (AUD)
- Global positioning system module (GPS)
- Subwoofer module (SUB)
- Phone module (PHM)
- Media player module (MPM) or integrated audio module (IAM)
If the minimum configuration of control modules on the MOST network is used in the vehicle, the following control modules are connected (when the vehicle is fitted with a media player module (MPM))
- infotainment control module (ICM)
- media player module (MPM)
- AM/FM tuner module (AFM)
- audio module (AUD).
If, instead, the vehicle is fitted with an integrated audio module (IAM), an infotainment control module (ICM) is connected in addition to this.

The control modules should be placed in the following order
- Infotainment control module (ICM)
- Multimedia module (MMM)

- Audio module (AUD)
- Subwoofer module (SUB)
- Global positioning system module (GPS)

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.
