CONSTITUTION:When an operator operates key switches 3a of trouble diagnostic unit operation part 3 to indicate the method and range of a diagnosis, trouble diagnostic unit control part 2 reads the indication of the diagnosis and information on the method and range to display part 3b for display. In case of an indication error, a request for the reexecution of key operation is displayed. When the indication is correct, control part 2 exercises control following the procedure of the diagnostic judgement according to the contents of the indication and then compares the obtained diagnostic result to the normal value of a preset diagnostic result, deciding on the existence of abnormality. In case that the decision result is found abnormal, the details are displayed on the display part 3b and when it is found normal, on the other hand, information on the normalcy is displayed. Consequently, the diagnoses can easily be made with accuracy by disconnecting external equipments. |
