The upper electrical limit stop

is defined in the control unit does not
need to be learned.
As in the fully open position , the
shaft diameter is greater than
the thickness of the throttle
butterfly.
To enable the exact angular position of the throttle valve to be identified, angle senders for
throttle valve drive G187 and G188 must be learnt .
By moving the throttle valve into predefined positions, the values of the angle senders are stored
in the control unit (calibrated) and checked for plausibility. The state of the mechanics (terminals,
weak springs) in the throttle valve control part is determined by evaluating the throttle valve's
reaction speed.

Basic adjustment (adaption) ...

... involves not only learning the throttle
valve position, but also a complete check of
the throttle valve control part
... can be performed using the following
three methods:
• manually - provided the ignition has been
switched on for at least 24 minutes without
operating the starter or accelerator.
• automatically - provided the need for adaption
is acknowledged.
• specifically - by initiating basic setting 04 in
measured value block 60 (refer to Workshop
Manual)

Adaption conditions

For basic setting (adaption), the test
conditions described in the
Workshop Manual must be met.
The basic setting routine will be
cancelled if the test conditions are
not fulfilled while it is in progress.
