Abstract
A master device sends a continuation (or stop) message on a communication line without causing mutual collision on the communication line with a response message continuously sent from a slave device. When time T1 has elapsed since completion of sending of a request message, a failure-diagnosis tester 5 (master) performs setting to send a continuation message when an idle counter has exceeded P3', and along with this, an engine controller 1 (slave) performs setting to send a subsequent response message when an idle counter has exceeded P2' (>P3'). Through this, the continuation message can be sent from the failure-diagnosis tester 5 prior to the engine controller 1 sending the subsequent response message, without causing the two messages to mutually collide on the communication line.
