Location

The instrument cluster is located in the dashboard on the driver-side.

Task

The instrument cluster has the following tasks:

Reading in of sensors and signals
Evaluation of input factors
Actuation of components
Output of warning tones and indicator tones
Output of signals

Reading in of sensors and signals

The instrument cluster reads in the input factors via the following connections:

Interior CAN (CAN B)
Chassis CAN (CAN E) (up to 28.02.2013) or chassis CAN 2 (CAN E2) (as of 01.03.2013)

Interior CAN

The signals are read in by the instrument cluster over the interior CAN. The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

Chassis CAN (CAN E) (up to 28.02.2013) or chassis CAN 2 (CAN E2) (as of 01.03.2013)

The signals are read in by the instrument cluster via the chassis CAN up to 28.02.2013 and via chassis CAN 2 as of 01.03.2013.

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

Evaluation of input factors

The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.

Actuation of components

The instrument cluster directly actuates all internal components (e.g. indicator and warning lamps, stepper motors of displays, multifunction display) as well as the instrument illumination.

Output of warning tones and indicator tones

For the output of warning and indicator chimes which are requested by the systems installed in the vehicle, the instrument cluster actuates the warning buzzer (A1h1) or the acoustic function check for turn signal lights (A1h2) (output of turn signal ticking).

Output of signals

The signals are issued over the following connections:

Interior CAN
Chassis CAN (up to 28.02.2013) or chassis CAN 2 (as of 01.03.2013)

Interior CAN

The signals are sent by the instrument cluster over the interior CAN.

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

Chassis CAN (up to 28.02.2013) or chassis CAN 2 (as of 01.03.2013)

The signals are sent by the instrument cluster via the chassis CAN up to 28.02.2013 or via chassis CAN 2 as of 01.03.2013.

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
