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.
