General information
The instrument cluster (A1) has the following functions:
- Information about important vehicle operating conditions (e.g. speed, amount of fuel ...)
- Provides warnings of critical operating conditions
- Display of various systems (e.g. audio, trip computer ...)
- Functions as computer and display for the "Active Service System" (ASSYST)
- Functions as a trip computer
To perform these functions, the instrument cluster (A1) is equipped with the multifunction display (A1p13), various meters and gauges, warning and malfunction indicator lamps as well as an acoustic transmitter. The instrument cluster (A1) also generates various signals (such as "Speed", "Terminal.58d" ...) for transmission to the engine compartment CAN and/or interior compartment CAN.
Except for the signal for the airbag indicator and warning lamp (A1e15), all of the required information from the various control units is transmitted to the instrument cluster (A1) via the engine compartment CAN or the interior compartment CAN.
Only a few wires are required to connect the instrument cluster to the rest of the vehicle. The instrument cluster (A1) is equipped, therefore, with just one connector.
The instrument cluster contains a microprocessor to process the incoming data. The program and necessary data are stored in an electronic memory chip. The program is operated using the system selection button (S110s3), the scroll forward/back button (S110s1) on the multifunction steering wheel and the two buttons on the instrument cluster (A1).
Diagnosis is performed with the STAR DIAGNOSIS TOOL.
