<p>Provided are a relay device where a routing table can be replaced in order to accommodate diverse relay variations and the storage capacity of the routing table can be saved, a communication harness including the relay device and a communication system including the relay device. In the relay device, a routing program for a CPU to execute relay processing and a routing table for identifying the relay destination by the relay processing are stored in an information rewritable flash memory. The routing table includes a first table that manages whether the CAN message is to be relayed or not, a second table storing the received CAN message, a third table storing the CAN message to be transmitted (relayed), a fourth table that manages the signal storage position, and a fifth table that manages the number of effective records in the second to fourth tables.</p> |
