1. AFLS ECU
2. ESP
Several control units are applied to electronically controlled vehicles. These units perform each control with informations from various sensors. Thus, sharing signal information from sensors is needed, so CAN communication type whose communication speed is high and insensitive to electrical noise by spark generation is adopted to controlling power-train(engine, atutomatic transaxle, ABS(ESP))AFLS ECU is input some informations(engine speed, steering angle sensor's signal, vehicle speed) in order to maintain optimum headlamp condition through CAN communication. AFLS ECU take cognizance of slope uses yaw rate sensor's signal.
AFLS ECU set this code If input value(yaw rate sensor's signal) is message signal timeout or invalid value.
