Headlight Leveling System
The headlight leveling system is composed of the headlight leveling control unit, the left-front and left-rear suspension stroke sensors, and the left and right headlight leveling motors.
The system uses the left-front and left-rear suspension stroke sensors to monitor the vehicle ride height. The ride height is monitored every 0.1 second while the vehicle is running with the headlight switch ON, and 3.6 seconds after the vehicles stops with the ignition and headlight switches ON.
If the control unit detects a ride height change, the control unit controls the headlight leveling motors to adjust the headlight vertical position.
