Anti-block device for wiper motor, function - GF82.30-P-4008SK

MODEL 171.4 

Lock-up recognition 

Wiper motor lockup (M6/1) is detected by the driver-side SAM control unit with fuse and relay module (N10/1) due to missing cam switch signals in the wiper motor (M6/1) during an active wiper operation.

Lock-up protection when wiping at level 2 

If the cam switch signal is missing for longer than 4 seconds the driver-side SAM control unit with fuse and relay module (N10/1) switches the wiper motor (M6/1) back to level 1.

If the signal remains off for a further 8 seconds the driver-side SAM control unit with fuse and relay module (N10/1) switches the wiper motor (M6/1) off.

If though during this 8 seconds a signal is received from the cam switch, the wiper motor (M6/1) is switched on again to stage 2.

Lock-up protection when wiping at level 1 

The driver-side SAM control unit with fuse and relay module (N10/1) switches the wiper motor (M6/1) off if no cam switch signals are received for longer than 12 seconds.

Canceling the lockup protection 

In all cases the lockup protection is canceled if:

• the corresponding function is requested by pressing the combination switch (S4) again or
• c. 15R is switched on again.
