54 0... Notes on panorama glass roof (initialization/normalization/learning of characteristic curve): Notes

WARNING: This page is about a different car, the 2013 BMW X5 M, 2012 BMW X5 M, 2011 BMW X5 M, and 2010 BMW X5 M. 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 panorama glass roof are recorded and stored for correct operation of the anti-trapping mechanism.
Initialization is started and implemented by pressing and holding switch in "Lift" direction.
Initialization depends on installed roof system and software used.

NOTE: Then carry out 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
After replacement of circumferential gasket

WARNING: The anti-trapping mechanism is not active during initialization.
For correct initialization and function, the following conditions must be met:

Ignition ON
at room temperature (23°C ± 5°C)
No direct solar radiation
only when vehicle is at a standstill
Fully charged vehicle battery
in addition, for US vehicles, let engine run to enable key, if necessary

NOTE: Subsequently described processes relate to a completely closed roof system. However, initialization can be started from any position.
