Infotainment Control Module (ICM)

Design

Display/printed circuit board





The infotainment control module (ICM) consists of a display and printed circuit board. The display is connected via a cable direct to the printed circuit board.

The display shows information about the function which is active. It also displays information when selecting functions and preferences for the system. The graphic display consists of a field with 128*64 pixels.

The printed circuit board has an input for display and input and outputs for:
- power supply
- ground
- The controller area network (CAN)
- LIN communication and
- the MOST network.

The processor for the infotainment control module (ICM) is on the printed circuit board. Therefore the printed circuit board contains all the functionality and logic for the infotainment control module (ICM). The printed circuit board also stores the software for the infotainment control module (ICM).

When replacing the control module reprogramming is required.

The control module can be diagnosed.

Remote controls





There is a remote control for the infotainment system. It is used for remote control of the navigation system. The remote control can be used to activate most of the functions that are controlled via the keypads on the climate control module (CCM)and via the buttons on the steering wheel.

The remote control transmits signals via the IR signals to the receiver unit which is located in the grille for the center loudspeaker in the dashboard. The signals then continue via the directly connected cable to the infotainment control module (ICM) which controls the selected function.
