Headlamp Functionality - Fusion/MKZ
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When the low beams are requested (based on inputs to the SJB), the low beams are illuminated.
Vehicles equipped with High Intensity Discharge (HID) headlamps utilize a relay to provide voltage to the ballasts. When the HID relays are energized, the ballasts provide the required high voltage to illuminate the HID bulbs.
When the high beams are requested, the high beams are illuminated and the low beams turn off.
When the flash-to-pass feature is requested, the high beams are illuminated as long as the multifunction switch is held in the FLASH-TO-PASS position.
