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 at the multiplex communication circuit.
When it detects raindrops that are stuck to the detection area on the windshield glass, it sends the wiper control signal according to the amount of raindrops to the Windshield Wiper ECU.
