Location 

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

Task 

The instrument cluster has the following tasks:

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

Reading in of 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) 
• Chassis CAN 2 (CAN E2) (as of 01.03.2013) 

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) 

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

Chassis CAN 2 (as of 01.03.2013) 

The signals are read in by the instrument cluster over the interior CAN.

The signals are read in by the instrument cluster via chassis CAN 2. 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 relevant 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) 
• 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) 

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

Chassis CAN 2 (as of 01.03.2013) 

The signals are sent by the instrument cluster via chassis CAN 2. The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
