54 0...Notes On Steel And Glass Slide/Tilt Sunroofs (Initialization/Normalization/Learning Of Characteristic Curve)

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.

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

Normalization:
- Press and hold slide/tilt sunroof switch in the "Lift" direction.
- In the event of delayed starting or sudden stopping of the slide/tilt sunroof, continue pressing the switch in the "Lift" direction.
- After reaching lift end position, keep switch pressed for approx. 20 seconds further.
- Normalization is only completed when the slide/tilt sunroof closes.
- Release switch.

Learning characteristic curve:
There are two procedures - depending on the diagram of the slide/tilt sunroof module.
- Characteristic curve is established by means of coding data, i.e. an actual sequence for learning the curve is not necessary.
- Characteristic curve is not established by means of coding data, i.e. the curve must be learnt by the slide/tilt sunroof module in stages.

The characteristic curve not established by means of coding data is learnt manually in the following stages:
- Release slide/tilt sunroof switch after normalization for max. 5 seconds.
- Then hold down the switch in the raising position direction until such time that the slide/tilt sunroof has returned to the closed position after a complete opening movement.
- This concludes learning of the curve. The switch can now be released.

Note: Carry out function check (one-touch function, anti-trapping protection and, if necessary, comfort function).
