Adaptive Headlighting
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles equipped with adaptive front lighting have a Headlamp Control Module (HCM) to control the left/right swiveling of the headlamp bulbs. Depending on the inputs received (steering wheel angle and vehicle speed for example), the adaptive front lighting module HCM can change the angle at which the headlamps are aimed (left or right) to improve nighttime visibility around curves.
The swiveling motor within each headlamp (used to control the angle of the headlamp beams) are part of the headlamp assembly and cannot be repaired separately.
