Rear Window Washer

When the wiper/washer switch is pushed away from the driver, the SASM sends the request to the BCM through the LIN. The BCM energizes the rear washer relay (internal to the BCM) and activates the rear window wiper motor. When the BCM activates the rear window wash relay, voltage is provided to the washer pump, directing washer fluid to the rear window. When the switch is released, the rear window wiper motor continues to operate for 3 additional wipes and then turns off.
