Instrument cluster (IC), function - GF54.30-P-0002TM
MODEL 211.0/2 as of 1.6.06 except CODE (494) USA version except CODE (498) Japan version
MODEL 211.0/2 as of 1.7.06 with CODE (494) USA version with CODE (498) Japan version
The instrument cluster supplies driver information for all systems installed in the vehicle:
- Display of vehicle operating conditions
- Warning about critical operating conditions
- Central display for various systems
- Display for Active Service System PLUS (ASSYST PLUS)
- Trip computer (TRIP)
Integrated within the instrument cluster are:
- multifunction display (A1p13)
- Various display instruments
- Warning and indicator lamps
- Warning buzzer (A1h1)
- Acoustic turn signal indicator (A1h2)
In addition the instrument cluster transmits and receives signals via the Controller Area Network bus Class C (engine compartment) (CAN C) and Controller Area Network bus Class B (interior) (CAN B).
The instrument cluster is operated by:
- Left multifunction steering wheel pushbutton group (S110)
- Right multifunction steering wheel pushbutton group (S111)
- Instrument illumination brightness control and reset button (A1r1)
The airbag indicator and warning lamp (A1e15) is not actuated via CAN-B but via a discrete line.
Diagnosis takes place via STAR DIAGNOSIS.
Activating the instrument cluster
Due to the black screen technology, the details on the instrument cluster do not become visible until the instrument cluster is activated. When the instrument cluster is activated, the displays show the current information, the illumination of the instrument cluster is switched on and the fuel reserve warning lamp (A1e4) is actuated. The instrument cluster is activated by the circuit status "circuit 15g ON". When circuit 15g is switched off, the instrument cluster remains active for a further 30 s. This run-on time may be extended by 2 min if active warnings occur.
If "circuit 15g OFF", the instrument cluster is activated in the following circumstances:
- By pressing the instrument illumination brightness control and reset button for 30 s
- By opening or closing of the driver door for 30 s
- By switching on the standing lamp or low beam until the request is canceled
If one of the above conditions occurs while the instrument cluster is already active, the instrument cluster remains active for an additional 30 s from this time. It is not possible to activate the instrument cluster by pressing the buttons on the multifunction steering wheel (MFL).
