Windshield Washer

When the washer switch is pulled towards the driver, the SASM sends the windshield wash request to the BCM over a LIN. The BCM activates the windshield washer relay (internal to the BCM) and the windshield wiper on/off relay. When the BCM activates the windshield washer relay, voltage is provided to the washer pump, directing washer fluid to the windshield. When the wiper/washer switch is released, the BCM continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.
