Windshield Washer

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