Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Adaptive Headlighting
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.
