To enable fault to be diagnosed without causing radio interference even though the same ID is shared in order to prevent the exhaustion of an ID for fault diagnosis.SOLUTION: A fault diagnosis unit 5 and a fault diagnosis tool 4 communicates with each control device 1 to diagnose fault using the same ID for fault diagnosis. A gateway device 2 rejects request for fault diagnosis and continues fault diagnosis by means of the fault diagnosis tool 4 if the gateway device 2 receives the request for the fault diagnosis from the fault diagnosis unit 5 when the fault diagnosis tool 4 performs the fault diagnosis. The gateway device 2 also performs adjustment as to which fault diagnosis is prioritized in accordance with a targeted control device 1 of fault diagnosis if the gateway device 2 receives a request for fault diagnosis from the fault diagnosis tool 4 when the fault diagnosis unit 5 performs fault diagnosis.SELECTED DRAWING: Figure 1

    【課題】故障診断用IDの枯渇を防ぐために同じIDを共有しても、混信が生じることなく故障診断を行えるようにする。【解決手段】故障診断ユニット5および故障診断ツール4は、同じ故障診断用IDを用いて、各制御装置1と通信を行って故障診断を行う。ゲートウェイ装置2は、故障診断ツール4が故障診断を行っているとき、故障診断ユニット5から故障診断の要求があると、この要求を拒否し、故障診断ツール4による故障診断を継続する。また、ゲートウェイ装置2は、故障診断ユニット5が故障診断を行っているとき、故障診断ツール4から故障診断の要求があると、故障診断のターゲットの制御装置1に応じて、いずれの故障診断を優先するかの調停を行う。【選択図】図1
