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 (applies to the C70): 

  1. Infotainment control module (ICM)
  2. Multimedia module (MMM)
  3. Audio module (AUD)
  4. Subwoofer module (SUB)
  5. Remote Digital Audio Receiver (RDAR)
  6. Phone module (PHM)/ Bluetooth phone module (BPM)
  7. Integrated Audio Module (IAM)
  8. Accessory USB unit (AUU)
