Abstract
An apparatus for diagnosing failures in a plurality of control units is provided in a control system. The apparatus has a detection device provided outside of the control units for comparing output data representing processing results of the control units to detect disparity of the output data of the control units, and a device for determining that a failure has occurred in at least one of the control units when the detection device detects the disparity of the output data.
