Rain Sensor Circuit

Rain Sensor Circuit

DESCRIPTION
This circuit provides power to operate the rain sensor.

The auto wiper system operates when the wiper switch is in the AUTO position.

The rain sensor is connected to each ECU through the multiplex communication line. When the rain sensor detects raindrops in the detection area of the windshield glass, the sensor sends a wiper control signal according to the amount of raindrops to the main body ECU LH. The rain sensor also sends signals to the dynamic radar cruise control system and the mirror defogger system.
