摘要： A communication system includes a master communication device and slave communication devices. The master communication device obtains information indicative of communication characteristics. The communication system records a combination of the master communication device and at least one of the slave communication devices having a communication abnormality. The system finalizes an abnormal position where the abnormality is occurring when an abnormality-determined position is consistent with a recorded combination of the master communication device and the at least one of the slave communication devices having a communication abnormality.
