An adaption of the original lower mechanical stop is only necessary to perform if the engine control unit, or the throttle control unit , has been replaced. When the adaption has been performed, the engine and throttle control units are a component combination and the lower mechanical stop starting positions is registered in the engine control unit´s memory.
Note:
When a used throttle control unit is used, it is necessary to clean it correctly before an adaption of the throttle control unit (original lower mechanical stop) is performed. If the throttle control unit is dirty, when the adaption is performed, the driving ability can be reduced and the throttle can be stuck in the lower mechanical stop.
After an adaption of the original lower mechanical stop has been done, it is also necessary to make an adaption of the current lower mechanical stop´s basic setting.
Test prerequisites:
Ignition on, engine off.
The battery voltage should be above 11.5 V.
The throttle pedal should be inactive when the adaption is performed.
The intake air temperature should be at least 6 °C.
The throttle control unit should be cleaned (if used).
Procedure:
Chose the function: Throttle control unit (original lower mechanical stop).
During the adaption "Adaption running" shows in the adaption status field.
When the adaption has been performed, "Adaption OK" / "Adaption ERROR" is displayed.
The adaption is finished. Exit the function.
Switch off the ignition and wait at least 50 seconds to store the values.
Continue with the function: Throttle control unit (current lower mechanical stop). See help for this function.
