PURPOSE: An electronic control circuit of a wheel lock prevention system is provided to obtain simple structure of an electric wire by using an IC(Integrated Circuit) element of a power solid state relay instead of an electromechanical relay and to display a normal operation of the wheel lock prevention system with a high-brightness LED(Light Emitting Diode). CONSTITUTION: An electronic control circuit of a wheel lock prevention system includes: a storage battery(1) supplying power necessary for operating an electric device of a vehicle; first to fifth fuses(F1-F5) isolating power of the storage battery immediately when an excess current flows exceeding a rated current of the fuses; an ignition switch(S1) contacted with the fifth fuse(F5); a DC motor(5) driving a hydraulic pump; an ABS(Anti-Brake System) lamp(6) displaying normal operation of a wheel lock prevention system through an ABS OK display(7) on a gauge panel with a high-brightness LED; and an electronic controller(70) preventing vehicle wheels from locking by controlling hydraulic pressure in brake calipers and controlling drive of a hydraulic pump by rotating the DC motor or not. The electronic control circuit adopts an IC relay included in the electronic controller instead of an electromechanical relay. Therefore, the electronic control circuit obtains simple structure of electric wire and saves a mounting space of components.
