Furthermore, the diagnostic selecting unit determines whether to diagnose the component in accordance with the result of comparing the read failure rate of the component and a failure rate reference value that is stored in a diagnostic reference value database. Furthermore, the diagnostic module delivery server transmits, to the maintenance target server, a diagnostic module that is used to diagnose the component in which it is determined, by the diagnostic selecting unit, that the diagnostics is to be performed.
