Synchronizing sliding/pop-up roof, function - GF77.20-P-3002PP

MODEL 203.0 /2 with CODE (414a) Electric glass sliding/pop-up roof 

Function 

Synchronization must be performed if desychronization has taken place previously.

Performing synchronization 

Open the pop-up roof with the roof system switch (N70s1) until the mechanical stop is reached and continue to actuate the roof system switch (N70s1).The overhead control panel control module (N70) continues to actuate the roof system motor (M12m1) and sets the position counter to zero when it has recognized that the roof system motor(M12m1)has been locked up for at least t=0.5 s.

Before reaching the lock-up position, at least 3 edges must have been recognized from Hall sensor 1 (M12b1) and Hall sensor 2 (M12b2)

It is not possible to synchronize the sliding/pop-up roof with the "Convenience opening, convenience closing" and "Automatic opening/closing" features, because these functions are not possible in the desynchronized state.

The sliding/pop-up roof is then in the synchronized state, i.e. the overhead control panel control module (N70) can switch off the roof motor system (M12m1) when the sliding/pop-up roof is being opened/closed in the automatic mode before reaching the mechanical stop.
