Abstract
Provided are a communication system and method that can block transmission of an abnormal message while allowing transmission and reception of an authorized message. The communication device includes a communication processing unit that sequentially outputs a binary transmission message, a first switch connects a first wire of a bus to a first potential and a second wire to a second potential, an abnormality detection unit detects an abnormality in a message transmitted on the bus, a switching control unit switches, if an abnormality has been detected, the first switch so that the first wire is connected to the first potential and the second wire is connected to the second potential, and a second switch connects the first wire and the second wire via a second resistor. The communication device transmits a message if no abnormality has been detected, and transmits a message if an abnormality has been detected.
