Test E: The Wash and Wipe Function Is Inoperative
PINPOINT TEST E: THE WASH AND WIPE FUNCTION IS INOPERATIVEE1-E3:
E4:
Normal Operation
The wash/wipe function is activated when the wiper motor module (internal) receives a reference signal through circuit 31S-KA19 (BK/RD). When the multifunction switch wash button is pressed for longer than 0.25 second, the windshield wiper motor cycles, sending battery voltage through circuit 30S-KA7 (RD/WH) to the washer pump motor. If the wash button on the multifunction switch is pressed for less than 0.25 second, the windshield wiper motor only cycles once, which is considered the mist position.
Possible Causes
- circuit 31S-KA19 (BK/RD) open
- multifunction switch
