Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Infotainment Theft Protection (ITP)
This function is used to ensure that all control modules on the MOST network and High Level Display Front (HLDF) can be used. When the MOST network starts up, the infotainment control module (ICM) checks that all control modules on the MOST network and High Level Display Front (HLDF) have approved serial numbers. If the infotainment control module (ICM) detects that one or more control modules do not have approved serial numbers, these modules will be set to "disable mode". This means that the control module functions cannot be used in the MOST network. The control module only acts as a conduit for the light pulses.
It takes 30 seconds for the infotainment control module (ICM) to check the control modules. This means that non-approved control modules will be disabled after 30 seconds.
