P54.30-9047-06

A1 Instrument cluster

Location

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

Task

The instrument cluster displays the dynamic and static status of the vehicle.

It also controls:

 Input/output signals on CAN-B and CAN-C for the various operations, displays and warning messages

 Illumination of the multifunction display (A1p13) depending on:

 the brightness buttons +/-

 the rain/light sensor (B38/2)

 the phototransistor

-----------------------------------------------------------------------------------------

 Outputs to the multifunction display

 Displaying the time using an analog clock

 Reading in the brightness buttons +/-

 Reading in the reset button (R)

The acoustic warning and information signals are output by a speaker that generates the turn signal indicator clicking sound using a relay:

 Flashing "ON" (turn signal indicator clicking sound)

 Lights ON warning (gong)

 Parking brake warning (gong tone)

 Key reminder (gong tone)

 National vehicle speed warning (gong tone)

 Door warning (gong tone)

 Child safety lock (gong tone)

 Front passenger airbag shutoff by ACSR automatic child seat recognition (gong tone)

 Seat belt reminder warning (gong tone, audible beep)

 Engine oil level warning (gong tone)

-----------------------------------------------------------------------------------------

 Configurations which can also be set while driving are with the exception of:

 Switch daytime running lamps on/off

 Engine oil level measurement

 Key dependency

 The instrument cluster actuates the stepper motors of the following analog displays:

 Tachometer (A1p5)

 Electronic clock (A1p6) (analog display)

 Electronic speedometer (A1p8)

 Fuel supply and reserve indicator (A1p2)
