Rain Sensor Circuit

RAIN SENSOR CIRCUIT

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 in the detection area of the windshield glass, the rain sensor sends a wiper control signal to the front controller according to the amount of raindrops detected.

It also sends signals to the adaptive laser radar cruise control system, the mirror defogger system and others.
