Note: Document of available Check-Control messages in BMW diagnosis system.
The service functions include a tabular list of Check-Control messages listed by their identification numbers.
Path: Service functions > Vehicle information > Check-Control messages.
The following control units remain important for the function of the instrument cluster:
-
Headset and Central Information Display
For the instrument cluster, the headset (M-ASK, CHAMP, CCC) serves as the interface to the Central
Information Display (CID). The CID displays detailed texts concerning Check-Control messages and information
about CBS and other on-board computer functions. The CID also enables the driver to change the units of
measurement (e.g. Celsius to Fahrenheit, and vice versa) for the instrument cluster.
Moreover, the headset establishes a telephone connection when a CBS maintenance operation is due (=
TeleService). This is achieved by sending a message to the telephone control unit via the MOST.
-
EGS: Electronic transmission control
The EGS control unit supplies the signal for the gear engaged to the instrument cluster. The selected gear is
shown in the selector-lever and shift indicator in the LCD display.
> E6x from 03/2007 and E70
The gear is selected with the gear selector switch (GWS). The GWS is a control unit in its own right on the PT-
CAN.
-
Car access system
The CAS control unit serves for redundant data storage. The following are stored in the CAS control unit
(redundantly to the instrument cluster):
•
Vehicle identification number
•
Odometer status
•
CBS data
-
Integrated automatic heating/air-conditioning system - only E6x up to 03/2007
The IHKA calculates the condition of the microfilter. The condition of the microfilter is CBS maintenance
operation.
The instrument cluster internally controls the following instruments and indicators:
-
Analogue instruments and moving-disc indicators
The instrument cluster incorporates a number of instruments that operate with step motors, namely:
•
Speedometer
•
Revolution counter
•
Fuel gauge
•
Fuel consumption indicator (E60, E61, E70)
•
Engine oil temperature (E63/E64)
•
Moving-disc instrument for the speed setting of the cruise control system
•
Moving-disc instrument for variable engine speed warning zone (currently only M-Technology)

Indicator and warning lights:
The single-colour indicator and warning lights that are required by law at the top, centred between the two large
analogue instruments (exception: turn signal indicator lights at sides).
The most important indicator and warning lights briefly light up during the pre-drive-check when terminal 15 is
