To enable easier change of a self-diagnostic program for making a contribution towards improvement in quality of the same program, even if it is required to correct an execution condition for fault detection due to the change of a diagnosis object, a diagnostic drive determination object 200 is provided to determine the execution condition of a fault detection object 300 driven from a diagnostic scheduler object 100. The diagnostic scheduler object 100 determines the fault detection object 300 of the drive object and requests the drive acknowledgment to the diagnostic drive determination object 200. Upon issuance of the drive acknowledgment request, the diagnostic drive determination object 200 obtains the information required for the execution condition determination and notifies a drive acknowledgment/non-acknowledgment message. Only when the acknowledgment message is notified, does the diagnostic scheduler object 100 issue a drive instruction to the fault detection object 300 of the diagnostic object.
