The fuel consumption signal...
... is a data message which is conditioned by
the engine control unit. The sum total of the
high levels during a defined period of time
corresponds to the injected fuel quantity.
... is required by the dash panel insert to
calculate fuel consumption and range.
The interfaces of the cruise control system (CCS) ...
... are linked to the controls on the steering
column switch.
Cruise control is executed by the
engine control unit by means of the
electronic accelerator function.
Road speed can be kept constant as
of approx. 25 kph.
The CCS must be enabled or disabled using
the “login procedure“ function (as with TDI
engines).
When the control unit is enabled, a “G“
appears in the control unit identification (refer
to Workshop Manual).
