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: 

1. Infotainment control module (ICM)
2. Multimedia module (MMM)
3. Audio module (AUD)
4. Subwoofer module (SUB)
5. Traffic message channel module (TMC)
6. Global positioning system module (GPS)
7. Phone module (PHM)
8. Integrated audio module (IAM)

If the minimum configuration of control modules on the MOST network in the car is used, the following control modules are connected:

• Infotainment control module (ICM)
• Integrated audio module (IAM)
