General Information: General Description

AHLS provides driver with the best visibility by adjusting vertical direction of the headlamp. It consists of ECM, Linkage and actuator. The ECM detects the vehicle speed to use it a compensation factor for the actuator control. In other words, when the vehicle speed is low the actuator needs to respond slowly though the linkage of height sensor moves quickly (response filter value is high). But when the vehicle speed is high, ECM operates the actuator quickly in proportion to the height sensor variation.
