The instrument cluster (A1) discharges the following functions:

The instrument cluster (A1) is equipped with the multifunction display (A1p13), various display instruments, warning and indicator lamps as well as an acoustic sensor.

In addition various signals are processed in the instrument cluster (A1) and passed on to the Controller Area Network bus class C (engine compartment) (CAN-C) and/or to the Controller Area Network bus class B (interior) (CAN-B).

All the necessary information from various control units reaches the instrument cluster (A1) via CAN-C or CAN-B.

For this reason only a few lines are required to connect with the remaining vehicle components. The instrument cluster (A1) only has one connector.

The instrument cluster (A1) has a microprocessor to process the incoming data. The program and necessary data are stored in an electronic memory chip.

Operation takes place via the right multifunction steering wheel button group (S111), left multifunction steering wheel button group (S110) and via the trip odometer reset button (A1s3) on the instrument cluster (A1).

IMPORTANT Following replacement of the instrument cluster (A1) it will be necessary to enter the ID code using STAR DIAGNOSIS. The codings and kilometer reading are then transmitted automatically from a vehicle control unit to the new instrument cluster (A1) via the Controller Area Network (data bus/CAN bus) (CAN).
