Adaptive Front Lighting System
B1307 Air suspension ECU sensor signal invalid - General Information

Component Location





General Description

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, automatic transaxle, ABS, TCS, ECS) 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 drive Leveling Actuator-Intelligent Stepper Motor to control headlamp by height sensor's signal.

DTC Description

AFLS ECU set this code If input value (height sensor's signal) is out of available range.
