GF77.20-P-3009T Panoramic Sliding Roof Synchronization, Function
- with CODE (413) Panoramic sliding roof



Function prerequisites:
^ Desynchronization must have occurred.

Carrying out synchronization
Close the panoramic sliding roof by means of the roof system switch (N70s1) to the mechanical limit stop. Continue to actuate the roof system switch (N70s1).
The overhead control panel control module (N70) continues to actuate the panoramic sliding roof motor (M12/6m1) and sets the position counter to zero when it has recognized "lockup" of the motor for 0,6 s.
Before reaching the end stop position a minimum of 3 pulse edges must be detected on each Hall sensor.

Resynchronization
Only takes place when the fully open panoramic sliding roof has been normalized. However, so-called resynchronization is accomplished during the next subsequent Panoramic sliding roof closing operation. This resets the Hall sensor pulse count to zero.

Synchronization cannot be performed via the "Convenience opening", "Convenience closing" and "Automatic opening" functions.
