Preconditions for the test:
Ignition on.
No faults stored.
All electrical loads switched off.
Note:

This process takes about 10 seconds. After adaption, the throttle returns to the starting position briefly, then closes.
Read adaption status. Prescribed value It must change from ”Adaption in progress…” to ”Adaption OK!” / Adaption Error!”.
Quit the basic setting mode and switch off the ignition. For the basic setting to be stored, the ignition must remain switched off for at least 15 seconds.
