6. RAIN SENSOR RELATED CIRCUIT
The rain sensor has one connector with 4 pins and each pin has following function as shown in the
circuit diagram.
However, in this vehicle, the terminal No. 1 and No. 2 are for communications between STICS and the
rain sensor; the No. 1 terminal sends the detected value from the rain sensor to STICS then the STICS
drives wiper motor.
No.2 terminal sends the wiper and washer operation information such as
-
washer operation mode,
-
MIST mode, or
-
AUTO wiper position
to the rain sensor to recognize whether it is actual rain or it is in rain sensing wiper operation mode.
