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 acoustic and information warnings
- Output of signals
Reading in of signals
The instrument cluster reads in the signals via the following connection:
- Central CAN (CAN F)
Central CAN
The signals are read in by the instrument cluster via the central CAN. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
The central gateway control unit (N93) makes information from other control units on the central CAN available to the instrument cluster. The central gateway control unit serves as an interface with the following data bus systems:
- Interior CAN (CAN B)
- Diagnostic CAN (CAN D)
- Chassis CAN (CAN E)
- Front end CAN (CAN G)
Interior CAN
The central gateway control unit passes on signals provided on the interior CAN to the instrument cluster via the central CAN. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Diagnostic CAN
The central gateway control unit passes on signals provided on the diagnosis CAN to the instrument cluster via the central CAN. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Chassis CAN
The central gateway control unit relays the signals placed on the chassis CAN via the central CAN to the instrument cluster. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Front end CAN
The central gateway control unit relays the signals placed on the front end CAN via the central CAN to the instrument cluster. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Evaluation of input factors
The integrated microprocessor evaluates the input factors read in. The appropriate 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
The instrument cluster actuates the warning buzzer (A1h1) to issue acoustic and information warnings, which are requested by the systems installed in the vehicle.
The "audible turn signal indicator" is acoustically realized by actuating the acoustic turn signal lights function check (A1h2).
Output of signals
The output of signals is carried out over the following connection:
- Central CAN
- Chassis CAN
Central CAN
The signals are transmitted by the instrument cluster via the central CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Chassis CAN
The signals are sent by the instrument cluster via the chassis CAN. The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
