Wipe stop function - GF82.30-P-3010CE

MODEL 204.0 /2 with CODE (551) Anti-theft alarm system (ATA [EDW]) as of model year 2009 /YoM 08 

MODEL 204.3 with CODE (551) Antitheft alarm system (ATA [EDW]) 

MODEL 204.9 with CODE (551) Antitheft alarm system (ATA [EDW]) 

Function requirements, general 

IMPORTANT The electronic ignition lock control unit (N73) sends the status of circuit 15R to the front SAM control unit with fuse and relay module (N10/1) via interior CAN (CAN B).

Wipe stop in general 

The wipe/stop function serves prevents the wiper motor (M6/1) from being actuated by the front SAM control unit when the engine hood is open.

Function sequence for wipe stop 

If at a speed of v < 3 km/h an open engine hood is recognized via the status of the engine hood switch pedestrian protection + ATA [EDW] Hall sensor (A38/1) (with code (U60) Pedestrian protection) or of the left engine hood contact switch (S62/43) (without code (U60) Pedestrian protection), the corresponding wiping function is immediately aborted. The wipe stop function is interrupted at a speed of v > 6 km/h, i.e. the wiper motor is actuated as from this speed again.

The instrument cluster (A1) transmits the vehicle speed information to the front SAM control unit via the interior CAN.

The steering column tube module (N80) directly reads in the switch position of the combination switch (S4) and transmits it to the front SAM control unit via the chassis CAN (CAN E).

The status of the engine hood (open or closed) is defined using the status of the engine hood switch pedestrian protection + ATA [EDW] Hall sensor (with code (U60) Pedestrian protection) or of the left engine hood contact switch (without code (U60) Pedestrian protection).

The rear SAM control unit with fuse and relay module (N10/2) reads in the status of the engine hood switch pedestrian protection + ATA [EDW] Hall sensor (with code (U60) Pedestrian protection) or of the left engine hood contact switch (without code (U60) Pedestrian protection) and sends it via interior CAN to the front SAM control unit. The front SAM control unit interrupts the actuation of the wiper motor.
