Multifunction Switch
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.
The multifunction switch is mounted directly to the SCCM and controls the low/high-beam headlamps, flash-to-pass, turn signals, windshield wiper and washer and front camera washer (if equipped), by transferring the driver inputs to the SCCM. The high-beam headlamps, flash-to-pass and turn signals are communicated from the SCCM over the HS-CAN. The windshield wiper and front camera washer signals (if equipped) are communicated from the SCCM to the wiper motor internal module over the LIN. When the BCM receives the correct signal from the SCCM, the BCM activates the required component.
