Headlight Leveling System
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
The headlights leveling system is composed of the headlight leveling control unit, the front and rear suspension stroke sensors, and the left and right headlight leveling motors.
The system uses the front and rear suspension stroke sensors to monitor the vehicle ride height. The ride height is monitored every 1 second while the engine is running and when the engine is off with the ignition switch in the ON (II) position.
If the control unit detects a change in ride height, the control unit sends a signal to the headlight leveling motors to adjust the headlight's vertical position.
