GF82.30-P-3009SK Automatic Wiper Control Function

GF82.30-P-3009SK Automatic Wiper Control Function
- with CODE (345) Rain sensor

Component Identification:

Function prerequisite
^ Circuit 15R ON

Function
The automatic wiper control (rain sensor operation) function is switched on by turning the combination switch (S4) to position "I". The wiper motor (M6/1) is actuated depending on:
^ Ambient light conditions
^ Degree of windshield wetting
^ The vehicle speed
^ Outside temperature.

The rain/light sensor (B38/2) and the overhead control panel control unit (N70) evaluate the signals. The wiper motor (M6/1) is actuated via the Controller Area Network Bus Class B (interior) (CAN-B) (CAN) by the driver-side SAM control unit with fuse and relay module (N10/1).

Possible wiper levels:
^ Intermittent wiper with variable intervals.
^ Continuous wiping at the required wiping speed.

Emergency running
If the communication between the rain/light sensor (B38/2) and the overhead control panel control unit (N70) fails, intermittent operation is activated at fixed intervals (approx. 5 sec.). If automatic speed reduction is active the interval is approx. 7.5 sec.
