Normal Operation
WARNING: This page is about a different car, the 2012 Ford Pickup. 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 Steering Column Control Module (SCCM) sends the request to the wiper motor over the Local Interconnect Network (LIN). The wiper motor then supplies power to the washer pump, which directs washer fluid to the windshield.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Washer pump
- Windshield wiper motor
- SCCM
