Multifunction Switch
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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 high beam headlamps, flash-to-pass, turn signals and windshield wiper 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 signals are communicated from the SCCM to the wiper motor internal module over the Local Interconnect Network (LIN). The BCM activates the required components when the correct signal is received from the SCCM.
