CA 2592908

A control device diagnoses the operation of a bus arbiter that mediates bus usage requests output by multiple devices in the control device to satisfy both responsiveness and safety. A diagnostic module, implemented as an external diagnostic module, monitors signals related to the arbiter mediation and, if an abnormality caused by a signal sticking condition or an abnormality in a mediation control unit is detected, stops data transfer safely to prevent safety data from being output incorrectly.
