Abstract
In a computer system, a device for and a method of conducting self-diagnosis of failure such as a break and a short circuit of a data communication line remove difficulty of conducting the self-diagnosis of the break and the short circuit only by driving and monitoring the data communication line by itself. For this purpose, a diagnosis module receives information necessary for self-diagnosis from a monitoring module connected to the data communication line. The diagnosis module to conduct self-diagnosis is connected via a diagnosis communication line to the monitoring module to communicate diagnosis information between the modules.
