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 Head Unit (IHU) (4/185). The control module checks the serial number on all control modules in the MOST network and compares these with a list stored in the Central Electronic Module (CEM). The list is transmitted to the Infotainment Head Unit (IHU) via the Controller Area Network (CAN). The Infotainment Head Unit (IHU) retrieves data about the serial number of the control modules via the MOST network. The Infotainment Head Unit (IHU) compares the information with the stored serial numbers for the control modules.
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. 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 in the Infotainment Head Unit (IHU).
