Washer System (if not equipped with front video camera): Notes
WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
When the multifunction switch is placed in the WASH position, the SCCM sends the request to the windshield wiper motor through the LIN. The windshield wiper motor supplies voltage to the washer pump, which then directs washer fluid to the windshield.
