Instrument cluster, component description - GF54.30-P-6000MCU
MODEL 451.3/4
Shown on code (K07) Speedometer (miles)
Location
The instrument cluster is located in the dashboard on the driver-side.
Task
The instrument cluster has the following tasks:
- Gateway between Controller Area Network (data bus/CAN bus) (CAN) and Controller Area Network bus Class B (interior) (CAN-B)
- Receive the input signals from the CAN and CAN-B for the various displays and warning messages
- Reading in of the paddle shift for steering wheel gearshift (SAL) (S112) over the fanfare horns and airbag clock spring contact (A45) (with code (I75) Leather sport steering wheel with steering wheel rocker switch system)
- Reading in the outside temperature display temperature sensor (B14)
- Determining and displaying the vehicle speed
- Illumination of the multifunction display, the dial face, the pointers and displays depending on the dimmer stage
- Display of dimmer stage over circuit 58d
- Actuation of warning and indicator lamps
- Output of acoustic signals
Acoustic signals
The acoustic warning and information signals and the turn signal indicator clicking are generated by means of an audio signal generator:
- Turn signal ON (turn signal knocking sound)
- Light warning (warning tone)
- Door warning (warning tone)
- Daytime running lights activated or deactivated (signal tone) (with code (K06) Daytime running lights)
- Seat belt reminder warning
Actuation of stepper motors
The electronic speedometer is driven by a stepper motor.
Variable displays in the multifunction display
The following displays are shown in the multifunction display:
- Fuel level and reserve indicator
- Transmission mode display in automatic mode
- Gear indicator or gearshift recommendation in manual mode
- Main odometer
- Multifunction display for remaining fuel, trip odometer and maintenance interval display
- Time display
- Ambient temperature display
- Transmission mode display
- Display of gear engaged or gearshift recommendation in manual mode
