PURPOSE: A failsafe diagnosis method of driving a motor for an anti-lock brake system is provided to measure the voltage of a driving motor to determine a failure by supplying a driving voltage in short time when the driving motor is not working. CONSTITUTION: A diagnosis method of a driving motor for an anti-lock brake system is comprised of steps: determining whether the state of a driving motor is controlled through a micro control unit(S1); determining a fail test is available when the driving motor is not controlled(S2); securing a time when a drive voltage is supplied to the driving motor is larger than a reference time(S3); completing the supply of a test drive signal to the transistor(S4); and detecting the voltage of the driving motor and converting it to a converted voltage(S5). |
