Function Sequence For Control/Warning Messages
The combination meter informs the driver about the functionality and status of the installed vehicle systems. Safety-relevant system activities and system malfunctions are shown to the driver in the form of control and warning messages.
The following display options are used for this purpose:
- Visual:
- Indicator lamps (green, yellow or blue)
- Warning lamps (red)
- Information display
- Acoustic:

The combination meter is connected to the vehicle electronics via the CAN communication.
Requests to issue control and warning messages from control units that are connected to one of these CANs are read in by the combination meter via the CAN communication.
Requests to issue control and warning messages from control units that are connected to one of the CANs are transmitted by the electronic ignition switch control unit via the CAN communication to the combination meter:
