<p><P>PROBLEM TO BE SOLVED: To easily and properly specify a failure cause without using complicated determination logic, even if other ECUs continuously detect an abnormality by the abnormality of one ECU, when data is transmitted/received between the plurality of EUCs to execute coordinated action. <P>SOLUTION: When the plurality of ECUs respectively store an abnormality diagnosis result obtained by self-diagnosis and receives an abnormality diagnosis result read-out command for reading out the abnormality diagnosis result from the outside, it is checked whether input abnormality from other ECUs is included in the abnormality diagnosis result or not. When the stored abnormality diagnosis result includes information indicating the input abnormality from other ECUs, the abnormality diagnosis result read-out command for reading out the abnormality diagnosis result stored in other ECUs is transmitted to other ECUs, and the diagnosis result obtained from other ECUs is transmitted to a transmitter of the abnormality diagnosis result read-out command as a response to the abnormality diagnosis result read-out command. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
