Task 

The instrument cluster control unit actuates all displays in the instrument cluster in the head unit/instrument cluster display cluster (A40/16). The instrument cluster control unit is connected to the network architecture of the vehicle via the user interface CAN (CAN HMI).

To display information, the instrument cluster control unit processes the following information among other things:

• Terminal status of terminal 15
• Fuel supply
• Engine speed
• Coolant temperature
• Outside temperature
• Requests to display system information
• Requests to output warnings
• Information on the on-board electrical system utilization

The instrument cluster control unit evaluates the incoming data and converts the included information for the display in the instrument cluster. The image data is transfered via the high speed video link (HSVL) interface to the instrument cluster.
