67 62... Notes on initializing power window regulator

WARNING: This page is about a different car, the 2013 BMW Z4, 2012 BMW Z4, 2011 BMW Z4, 2010 BMW Z4, and 2009 BMW Z4. 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 normalization, the mechanical end stops of the power window regulator are recorded and stored.

The characteristic curve is learnt immediately after normalization.

When the characteristic curve is learnt, the mechanical closing forces of the power window 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.

NOTE: An initialization must be performed:

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

WARNING: There is no anti-trapping protection during initialization.

Necessary preliminary tasks

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

Operating procedure for initialization (manual):

Erasure of initialization

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

NOTE: Deletion of initialization was successful if one-touch control function and anti-trapping protection have been rendered inoperative.

Performing initialization

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

NOTE: Re-initialisation was successful if one-touch control function and anti-trapping protection function flawlessly.

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