Abstract
An integrated IC provided in an SBW-ECU has plural functions such as a receiving function of receiving output signals of an encoder and a current supply function of supplying current to each phase of the motor. A microcomputer checks individually whether the signal receiving function and the current supply function are potentially abnormal and checks whether the integrated IC is abnormal based on the check results about the signal receiving function and the current supply function. For example, when it is determined that only the signal receiving function of the integrated IC is potentially abnormal, the encoder is determined to be abnormal. When it is determined that the signal receiving function and the current supply function of the integrated IC are both potentially abnormal, the integrated IC is determined to be abnormal.
