Throttle Unit Adaptation
If necessary the engine control module (ECM) runs an adaptation of the throttle unit by guiding the throttle to the limit positions (open/closed) so that it " learns" the parameters of that actual throttle unit.
The status indicates if the adaptation has been run or not.
OK = Adaptation of the throttle unit has run.
NOT OK = Adaptation of the throttle unit has not run.
NOTE:
The basic conditions must be met before an adaptation of the throttle unit can be carried out.
