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 Control Module (ICM)
The customer can personalize some of the central locking settings and the keyless lock system using the infotainment control module (ICM) (3/281). The infotainment control module (ICM) communicates with the central electronic module (CEM) and Keyless vehicle module (KVM) via the middle-speed side on the CAN network (MS CAN). The central locking settings are presented via a menu system in the display on the infotainment control module (ICM). For further information about the settings which can be made, see: DIAGNOSTIC FUNCTIONS
The settings for the central locking system are stored in the central electronic module (CEM). The settings for the keyless entry system are stored in the keyless vehicle module (KVM). Information from both control modules is transmitted to the infotainment control module (ICM) when the ignition is switched on.
For further information, see Design and Function, infotainment control module (ICM).
