SYSTEM / Electrical System WIPER / WASHER CIRCUIT Wiper Circuit 1. The wiper / washer switch sends the electrical signal on position the INT. in response to the set intervals to the monitor unit. 2. The monitor unit connects terminal #A2 to the ground according to the input intervals. 3. Therefore, the wiper relay repeats to turn ON and OFF. 4. When the wiper relay is turned ON, current from fuse #2 flows to the wiper motor and the wiper moves. Washer Circuit 1. While pushing the wiper/washer switch, the monitor unit receives the electrical signal from the wiper/washer switch. 2. The monitor unit connects terminal #A10 to the ground and the washer relay is excited. 3.
Current from fuse #2 flows to the washer motor and washer liquid jets. Fast Speed Middle Speed Slow Speed M178-01-016 Position ITN. Set Time Slow 8 seconds Middle 6 seconds Fast 3 seconds T2-5-24
