WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2018 BMW M6, 2018 BMW 650i xDrive, 2018 BMW 650i, 2018 BMW 640i xDrive, and 2018 BMW 640i. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Initialization
is performed on the power window switch of the relevant door.
Initialization comprises:
With normalization, the mechanical end stops of the power window regulator are recorded and stored.
The characteristic curve is learned immediately after normalization.
When the characteristic curve is learned, the mechanical closing forces of the power windows are recorded and stored for correct operation of the anti-trapping mechanism.
Initialization, i.e. normalization and learning of characteristic curve, is performed in a continuous operation.

- Normalization
- Learning characteristic curve
