ABSTRACT:
A sensor for detecting moisture on an outside surface of a windshield is disclosed. The sensor includes an emitter circuit for emitting light energy, and a detector circuit for receiving light energy. A processor controls the emitter circuit and processes signals received from the detector circuit. A self test circuit is connected between the processor and the emitter circuit, the self test circuit is operably associated with the emitter circuit for generating a test signal for simulating the presence of moisture on the outside surface of the windshield.
