54 0 ... Notes on steel and glass slide/tilt sunroofs (initialization/normalization/learning of characteristic curve): Notes
WARNING: This page is about a different car, the 2005 BMW 745i, 2004 BMW 745i, 2003 BMW 745i, and 2002 BMW 745i. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Initialization comprises:
- Normalization
- Learning characteristic curve
The mechanical end positions are recorded and stored during normalization.
The characteristic curve is learned immediately after normalization.
When the characteristic curve is learned, the mechanical closing forces of the slide/tilt sunroof are recorded and stored for correct operation of the anti-trapping mechanism.
NOTE:
Then carry out an initialization:
- if the slide/tilt sunroof has been mechanically moved by means of the emergency actuator
- in the event of malfunctions, e.g. no one-touch function, no opening or no comfort function possible
- after disengagement of the drive unit
- after work is carried out on the mechanism of the slide/tilt sunroof
- after the control unit has been replaced
WARNING:
There is no anti-trapping protection during initialization.
