Adaptive Front Lighting System
B1303 Accelerator Pedal Position Signal Error - 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 determine range performance to headlamp in according APS signal.

DTC Description

AFLS ECU set this code If input value (APS signal) is out of available range.
