Since 5/97 an instrument cluster has been phased-in which features the plugged-on instrument cluster electronics (IKE ) integrated in the display unit (AE ). This instrument cluster can replace older instrument cluster versions.
The fuel consumption signal tKVA is derived from the injection signal supplied by the engine control unit. By linking it with the position signal, it corresponds to the consumption per unit of distance (e.g. l/100 km).
In the case of the twelve-cylinder engine, the consumption is determined from the fuel injection signals of both engine control units and the position signal.
In the case of the integrated version of the instrument cluster, phased-in as from 5/97, the coding data defines whether the injection signal is routed via the CAN bus or via a separate line to the instrument cluster.
