Test A: The Wipers Are Inoperative

PINPOINT TEST A: THE WIPERS ARE INOPERATIVE

Normal Operation
When the smart junction box (SJB) receives input from the multi-function switch to activate the wipers, the SJB activates the RUN/PARK relay through circuit RRW24 (GN/VT). When the RUN/PARK relay is activated, voltage is supplied back to the SJB through circuit CRW03 (VT/WH) into the (integral) HIGH/LOW relay. The windshield wiper motor receives power from the HIGH/LOW relay (integral to the SJB) through circuit CRW16 (GY/BN) for low speed and circuit CRW15 (BN/WH) for high speed. The windshield wiper motor is grounded through circuit GD121 (BK/YE). The multi-function switch is grounded through circuit GD116 (BK/VT).
