Task 

The instrument cluster control unit controls all displays in the instrument cluster in the head unit/instrument cluster display cluster. The instrument cluster control unit is connected to the network architecture of the vehicle.

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 processes the incoming information and prepares it to be shown on the instrument cluster. On vehicles with head-up display, the instrument cluster control unit also prepares the information to be shown on the head-up display. The image data is transferred via the high speed video link (HSVL) interface to the instrument cluster or to the head-up display.
