CONSTITUTION:A watchdog timer 3 is operated to input a signal to a diagnostic processor 2. The processor 2 is operated to output test data to respective diagnostic ports 411-4n1 of elements 41-4n. After test data are stored in respective ports, the processor 2 outputs a read-in signal to each diagnostic port, and the diagnostic port receives this signal to output stored date to the processor 2. The processor 2 compares test data with data, which are read from respective diagnostic ports, for every element; and if they do not coincide with each other, an abnormality of a bus in a corresponding element is displayed. By this comparison collation, the abnormality of the bus is detected and recovered in the early stage.,下面是Abnormality detection for bus专利的具体信息内容。
