<p>PURPOSE:To enable a real trouble to be only detected by first deciding the trouble when a number of generation times of abnormality reaches a predetermined number of times or more. CONSTITUTION:An abnormality generation detecting means 5 diagnoses an operating condition periodically of a control load system 1. Abnormality, when it is generated in a certain control load system 1, is detected and counted by a counter 6 for use of the control load system 1. A counted number of times is stored in an area provided in every control load system of the first memory means 7. This data is further fed to a trouble decision means 8 and compared with the predetermined number of times, when the data is in this predetermined number of times or more, the control load system 1 is first judged as the trouble. The judgment result is stored in the second memory means 9 and displayed in a display device 2 as necessary by a trouble display control means 10. Accordingly, the abnormality, even when it is generated due to various electrical noises or the like, is prevented from being immediately judged as the trouble.</p> |
