Infotainment Theft Protection (ITP)
The Infotainment Theft Protection (ITP) function is designed to prevent non-approved control modules from being installed in the infotainment system. This is to prevent the theft of units.
The function is controlled by the infotainment control module (ICM). The infotainment control module (ICM) (3/281) checks the serial number on all control modules in the MOST network and the High Level Display Front (HLDF) (16/46) and compares these with a list stored in the central electronic module (CEM). The list is transmitted to the infotainment control module (ICM) via the controller area network (CAN). The infotainment control module (ICM) retrieves data about the serial 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. This function also applies to the High Level Display Front (HLDF), which communicates with the infotainment control module (ICM) via the controller area network (CAN).
If a control module is not included in the stored list or if a control module in the stored list responds incorrectly, then a diagnostic trouble code (DTC) is stored in the infotainment control module (ICM).
