Notes on initializing power windows

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 BMW M240i xDrive, 2023 BMW M240i, 2023 BMW 230i xDrive, 2023 BMW 230i, and 2022 BMW M240i xDrive. 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:

Normalization
Learning characteristic curve

With scaling, the mechanical end stops of the power windows are recorded and stored.

The characteristic curve is learned immediately after standardization.

When the characteristic curve is learned, the mechanical closing forces of the power windows are recorded and stored for correct operation of the crush guard.

Initialization, i.e. scaling and learning of characteristic curve, is performed in a continuous operation.

NOTE: An initialization must be performed:

In the event of malfunction, e.g. no one-touch mode, no opening or no convenience function possible.
After the power windows drive or door module has been replaced.
After work is carried out on the power windows mechanism.

WARNING: There is no crush guard during initialization.

Preliminary work needed:

Vehicle stationary
Sufficient battery voltage available/connect charger if necessary
Terminal "15" switched on
All doors closed

Operating procedure for initialization (manual):

Deleting the initialization:

Shift side window into lower end position.
Press and hold switch in "Open one-touch mode" position (second switch position) for between 15 and 25 seconds.

NOTE: Deletion of initialization was successful if toll function and crush guard have been rendered inoperative.

Performing initialization:

Shift side window to upper end position
Pull and hold switch in "Close one-touch mode" (2nd switch position) during the entire process.

NOTE: Re-initialization was successful if toll function and crush guard function flawlessly.

Alternatively, initialization of the power window regulation can also be carried out via the Service function in ISTA.
