Abstract

Abstract A fault diagnosing apparatus includes a fault tree, a storage section (3a), a read control section (3), a display section (4), a designating section (6), and a rewrite section (6), The fault tree is designed such that a plurality of choices are set with respect to one question associated with a cause of a fault of a fault diagnosis target, answers and choices branch off from each of the choices, and final choices reach causes of the fault. The storage section stores fault repair items with respect to the causes of the fault. In response to an input operation to select one of the choices, the read control section reads out the selected choice, a corresponding question, choices branching off therefrom, and fault repair items. The display section displays the question, the choices, and the fault repair items which are read out by the read control section. The designating section designates to update the fault repair items. The rewrite section rewrites some of the fault repair items stored in the storage section by using update data externally provided on the basis of the designation from the designating section.
