Function
The overhead control panel control module (N70) receives voltage pulses from the Hall sensor 1 (M12b1) and Hall sensor 2 (M12b2) located on the SR motor (M12m1) and evaluates them for position recognition.If the
voltage pulses are absent for longer than 0.6 s in spite of motion actuation, the overhead control panel control module (N70) recognizes lock-up and switches off the SR motor (M12m1).
If lock-up is recognized, the sliding/pop-up roof (SR) (M12) is always desynchronized.
