MODEL 230

Function requirements: 

Function 

The function washing is activated by pressing the combination switch (S4) beyond the catch point.

The windshield washer fluid pump (M5/1) is actuated by the front passenger-side SAM control unit (N10/11). At the same time the driver-side SAM control unit (N10/10) transmits the "Wash" information to the overhead control panel control unit (N70) to prevent wiping by the rain sensor (B38) or the rain/light sensor (B38/2).

If washing takes place whilst

Afterwiping 

The number of afterwipe processes depends on the time for which the combination switch (S4) is operated.

Afterwiping becomes active as soon as the combination switch (S4) is not longer being operated.

If the windshield washer fluid pump (M5/1) is requested for an operating time of less than 1 second, a single afterwipe is performed.

Actuating the switch for more than 1 second for the first time causes a triple afterwipe. If within the afterwipe period a new wash is actuated, then a triple afterwipe is always performed.

If afterwipe is active in level 2, then the afterwipe is also performed at level 2. If afterwipe is active during level 1 or intermittent wipe mode, afterwiping takes place at level 1; this also applies if the combination switch (S4) is in the park position.

IMPORTANT If the windshield washer pump (M5/1) is continuously requested for 15 seconds, the system detects a "hanging" button and actuation is stopped.
