Abstract: A communication system comprises a plurality of communication nodes that relay failure diagnosis communication of a diagnosis request and a diagnosis result between a request source of a failure diagnosis and a request destination of the failure diagnosis. At least one of the communication nodes is configured to determine whether current communication is the failure diagnosis communication, and to pack a first communication frame of a first communication protocol whose use is defined in a communication standard of the failure diagnosis into a second communication frame of a second communication protocol having a higher communication speed than the first communication protocol.

Abstract: A communication system includes a plurality of communication nodes that relay fault diagnosis communication of a diagnosis request and q diagnosis result between a request source and a request destination of the fault diagnosis. A communication setting unit of one of the communication nodes increases a priority of a priority parameter indicating the priority of communication when a communication determination unit determines that the present communication is the fault diagnosis communication either when transmitting the diagnosis request or when transmitting the diagnosis result.
