System Operation: Headlamps: Flash-To-Pass

WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.

The SCCM monitors the LH multifunction switch for a flash-to-pass request. When the LH multifunction switch is in the FLASH-TO-PASS position, the SCCM sends a message over the HS-CAN2 to the GWM then the GWM sends the message to the BCM over the HS-CAN1.

When the ignition is in RUN and the flash-to-pass is requested, the high beams are activated as long as the LH multifunction switch is held in the flash-to-pass position.
