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, pickups and signals
^ Evaluation of input factors
^ Actuation of components
^ Output of acoustic and information warnings
^ Output of signals

Reading in of sensors, pickups and signals
The instrument cluster reads in the input factors via the following connections:
^ Interior CAN (CAN B)
^ Chassis CAN (CAN E)

Interior CAN
The signals are read in by the instrument cluster over the interior CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).

Chassis CAN
The signals are read in by the instrument cluster over the chassis CAN.
The functions resulting therefrom are described in the corresponding 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 relevant components are then actuated.

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

Output of acoustic and information warnings
To output the warning and information sounds requested by the systems installed in the vehicle, the instrument cluster actuates the internal speaker ("chime") or the warning buzzer (A1h1).
The "audible turn signal indicator " is acoustically realized by actuating the acoustic turn signal lights function check (A1h2).

Output of signals
The signals are issued over the following connections:
^ Interior CAN
^ Chassis CAN

Interior CAN
The signals are sent by the instrument cluster over the interior CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).

Chassis CAN
The signals sent by the instrument cluster over the chassis CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
