Scheme 1
The headlight leveling system is composed of the headlight leveling control unit, the suspension stroke sensor, and the left and right headlight leveling motors.
The system uses the suspension stroke sensor to monitor the vehicle ride height. The ride height is monitored every 3 minutes while the vehicle is running with the headlight switch ON, and 8 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.
