Instrument panel On Board Diagnostic (OBD) (from MY 2000) (Page 01-86)
In vehicles from 05.99
the instrument cluster is connected to the power-train data-bus.
The databus is also referred to as CAN-databus.
Data can be exchanged between power-train databus and diagnostic wire (K-wire) via the
diagnostic interface for databus -J533- in instrument cluster.
The diagnostic interface for databus -J533- must be coded depending on the vehicle equipment
when replacing the instrument cluster

The instrument panel is controlled via a microprocessor which is equipped with an extensive self-
diagnosis.
If faults occur in the sensors and components being monitored, they will be stored in the fault
memory together with an indication of the type of fault.
A maximum of 4 faults can be stored simultaneously.
