WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
The headlight leveling control unit is located under the passenger's side of the dashboard. The headlight leveling control unit uses the voltage signals it receives from the left-front and left-rear suspension stroke sensors to determine the voltage signal (about 2-11 V) it sends to control the left and right leveling motors.
