54 00 ... Notes On Panorama Glass Roof (Initialization/Normalization/l 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 panorama glass roof are recorded and stored for correct operation of the anti-trapping mechanism.







NOTE:
Then carry out an initialization:
- if the panorama glass roof 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 panorama glass roof
- after the control unit has been replaced







WARNING:
- There is no anti-trapping protection during initialization.
- Ensure an adequate power supply during initialization.
- Start vehicle engine.







Normalization:
- Panorama glass roof can be initialized in each localized position
- Actuate switch during the entire procedure
- Actuate and hold switch in the first of the two possible positions in the "Close" direction







- Panorama glass roof moves a few centimeters
- Continue actuating switch in this position







Learning characteristic curve:

The curve is learnt in the following steps:
- After normalization, keep switch actuated and held in the Close direction in the first position
- Panorama glass roof closes completely after 30 seconds
- Panorama glass roof opens completely
- Then the panorama glass roof moves into the closed position
- Release switch.







NOTE:
- The entire operation lasts approx. 75 seconds
- Learning of the curve is terminated when the switch is released
- If the switch is released in the meantime, the entire procedure must be repeated
- On completion of successful initialization, the corresponding messages in the check control and the control display go out
- Carry out function check (tip function, anti-trapping protection and, if necessary, comfort function)
