Anti-lock protection for wiper motor, function - GF82.30-P-4008S

Models 215, 220 

Lock-up recognition 

Lockup of the wiper motor (M6/1) is detected by the left front SAM control module (N10/6) by the lack of signals from the cam switch.

Anti-lock protection for wiping in "stage 2" function 

If this signal from the cam switch is missing for more than 4 s, then the left front SAM control module (N10/6) switches the wiper motor (M6/1) to "stage 1".

If the signal is still missing for a further 8 s, then the left front SAM control module (N10/6) switches the wiper motor (M6/1) off.

Anti-lock protection for the functions one-touch wiping, intermittent wiping, washing and wiping in "stage 1" 

With these functions the left front SAM control module (N10/6) 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 if: the corresponding function is requested again by pressing the combination switch (S4) or "circuit 15R" is switched on again

If the wiper motor (M6/1) still locks after canceling the anti-lock protection, the wiper motor (M6/1) is switched off again as described above.
