A method of diagnosing an electrically operated brake (22, 32) for abnormality thereof in an automotive vehicle wherein a wheel (FL, FR, RL, RR) is braked by a friction force generated by an electric motor (20, 30) of the brake upon an operation of a brake operating member (34), the method comprising the steps of: applying an abnormality checking drive signal to the electric motor to operate the electric motor while the brake operating member is placed in a non-operated position; detecting a quantity (L, M1, M2, fA, GVw) relating to an output of the electric motor while the drive signal is applied to the electric motor; and determining that the electrically operated brake is abnormal, if the detected quantity does not normally correspond to a magnitude of the abnormality checking drive signal. <IMAGE> |
