If the windshield is wetted in the area of the rain/light sensor (picture B), then part of the light is scatted out of the windshield glass. As a result the
intensity of the reflected light reduces and the infrared receiver unit measures a low light intensity.
The light intensity measured by the infrared receiver unit represents a measure for the degree of wetting of the windshield. The smaller the measured
light intensity the greater the degree of wetting of the windshield.
The information is transmitted on the interior CAN via the overhead control panel control unit (N70).
