Abstract
A diagnostic device displays at least an optimum countermeasure in response to a failure code inputted in accordance with a failure of a machine, as a result of searching a countermeasure map, in which each failure code is associated with at least a countermeasure code. After taking a countermeasure with reference to display of the diagnostic device, the repairer inputs a countermeasure code corresponding to the taken countermeasure and a result code indicating the result of the countermeasure. The failure code, the countermeasure code and the result code are stored as repair data in the diagnostic device. The repair data is sent to a host computer over a telephone line. The host computer gathers the statistics of the repair data to revise the countermeasure map.
