Power window desynchronization, function - GF72.29-P-4002R

MODEL 230 

Desynchronization 

A desynchronization is performed in the following cases:

• If on the left door control module (N69/1), on the right door control module (N69/2) and on the RCV control module (N52), the voltage supply at circuit 30is < 6.5 V for a time period of more than 30 s.
• If the window reaches a position counter reading during manual or automatic lowering, which is larger than the maximum window path.
• If the window reaches a position counter reading during manual or automatic raising, which extends beyond the negative zero point tolerance or the stored zero point.
• If 1 of 2 Hall sensor signals for 12 rotations of the armature is faulty.

Following desynchronization automatic raising is no longer possible.
