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 2003 BMW X5 and 2002 BMW X5. 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 learnt immediately after normalization.
When the characteristic curve is learnt, the mechanical closing forces of the slide/tilt sunroof are recorded and stored for correct operation of the anti-trapping mechanism.
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 disengagement of the drive unit.
- If necessary, after an interruption of the power supply.
- After work is carried out on the mechanism of the slide/tilt sunroof.
NOTE:
The initialization sequence is dependent on the software version of the slide/tilt sunroof module (in the sunroof drive unit).
If necessary, code slide/tilt sunroof drive unit.
If necessary, code slide/tilt sunroof drive unit.
WARNING:
There is no anti-trapping protection during initialization.
