AFLS(Adaptive Front-Lighting System) provides driver with the best visibility by adjusting horizontal and vertical direction of the headlamp. It consists of AFLS ECU, Leveling Actuator-Intelligent Stepper Motor, Swivel Actuator, Head lamp switch, Height sensor(not applied to ECS). For efficient operation of system, AFLS ECU check Battery voltage.Battery function is supply power to AFLS ECU and Actuators.
AFLS ECU set this code If lower voltage input than available voltage to circuit, and discontinued operation in order to prevent from system malfunctioning.
