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 further control modules are added to the MOST network, these 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 compromised. The control modules should be placed in the following order:

1. Infotainment Control Module (ICM) (16/1)
2. Multimedia module (MMM) (16/108)
3. CD module (MP2) (16/106)
4. Phone module (PHM) (16/60)
5. MD module (MP1) (16/107)
6. Audio module (AUD) (16/105)
7. Subwoofer module (SUB) (16/79)
8. Antenna module (ATM) (16/110).

If the MD module (MP1) is installed as an aftermarket accessory in a car with a phone module (PHM) and CD module (MP2), the MD module (MP1) will change positions with the phone module (PHM).

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

• infotainment control module (ICM)
• the audio module (AUD)
• the antenna module (ATM).
