|
Reading in of sensors, pickups and signals
The instrument cluster reads in the input factors via the following connections:
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
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).

|
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 warning tones and indicator tones
|
To issue warning and information tones which are requested by the systems installed in the vehicle, the instrument cluster
actuates the warning buzzer or the acoustic function check for the turn signal lights (output of turn signal ticking).

Output of signals
The signals are issued over the following connections:
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
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).
