GF82.30-P-4008Q Anti-Block Device For Wiper Motor, Function

Lock-up recognition
A lockup of the wiper motor (M6/1) is detected by the front SAM control module with fuse and relay module (N10/1) due to the absence of signals from the cam switch in the wiper motor (M6/1).

Lock-up protection for function, wiping in stage 2
If the cam switch signal is missing for more than 4 s, then the front SAM control module with fuse and relay module (N10/1) switches the wiper motor (M6/1) back to stage 1.
If the signal does not appear for a further 8 s, then the front SAM control module with fuse and relay module (N10/1) switches off the wiper motor (M6/1)
If, however, during this 8 s a signal is received again from the cam switch, the wiper motor (M6/1) is switched up again to stage 2.

Lock-up protection for functions One-touch wiping, Intermittent wiping, Washing and Wiping in stage 1
With these functions the front SAM control module with fuse and relay module (N10/1) switches the wiper motor (M6/1) off, if the signals from the cam switch do not appear for more than 12 seconds.

In all cases, the anti-lock protection is canceled when
^ the corresponding function is requested again by actuating the combination switch (S4) or
^ circuit 15R is switched on again.

If the wiper motor (M6/1) locks up again after discontinuation of the lock-up protection feature, it is switched off again as described above.
