Portrayal of instrument cluster during lamp check
General information
The instrument cluster (A1) has the following functionalities:
- Provide information about important vehicle operating conditions (e.g. speed, fuel supply)
- Warn the driver about critical operating conditions
- Function as a display for various systems (e.g. audio, trip computer)
- Function as a computer and display for the "Active Service System" (ASSYST)
- Function as a trip computer
To support these functionalities the instrument cluster (A1) incorporates a left multifunction display (A1p13), a right multifunction display (A1p15), various display instruments, warning and indicator lamps, and an acoustic signaling device.
In addition, various signals are produced in the instrument cluster (A1) (e.g. "speed", "terminal 58D"...) and passed via the engine compartment CAN and/or interior CAN.
Virtually all of the required information, with the exception of the signal for the airbag indicator and warning lamp (A1e15), is relayed from various control units to the instrument cluster (A1) via the engine compartment CAN or the interior CAN.
For this reason, only a few lines are required to connect it with the rest of the vehicle. The instrument cluster (A1) therefore only has one connector.
The instrument cluster (A1) includes a microprocessor for processing the incoming data. The program and necessary data are stored in an electronic memory chip.
The instrument cluster (A1) is operated using the system selection button (S110s3) and scroll forward/back button (S110s1) of the multifunction steering wheel and the instrument illumination rheostat and reset button (A1r1) on the instrument cluster (A1).
Diagnosis takes place using STAR DIAGNOSIS.
