LIN (Local Interconnect Network) is direct communication system to low-cost for electric system of vehicle.height sensor signal, vehicle speed, steering angle sensor signal are input to AFLS ECU to find out of headlamp position and AFLS ECU drive actuators through LIN communication.
AFLS(Adaptive Front-Lighting System) drive Leveling Actuator-Intelligent Stepper Motor for adjusting up and down, and Swivel Actuator for adjusting right and left side.
AFLS ECU set this code If LIN communication line short to battery or ground.
almost cause of this DTC is LIN communication line or faulty headlamp.
