number of the control modules via the MOST network. The infotainment control module (ICM) compares the information with the stored serial numbers.
If a control module is not in the stored list, it is disconnected from the MOST network and the functionality of this control module is blocked. This
means that control modules in the MOST network cannot be moved from one vehicle to another.
A diagnostic trouble code (DTC) is stored in the infotainment control module (ICM) if a control module in the stored list gives the incorrect response.
