Procedure:
Start the function.
Select option 2 from the dropdown list.
The basic setting is activated - read the presented voltage value for the wastegate and compare it with the specified reference value.
If the value is within the tolerances, no further adjustment is necessary and the function can be terminated.
If adjustment is required, do as follows:
Select option 1 in the dropdown list.
The voltage value for the wastegate is now presented without having the basic setting activated, in this mode you can adjust the control rod.
