Abstract To prevent unauthorized access, and prevent processing loads from getting unnecessarily high.SOLUTION: When a relay device receives diagnostic data DD for diagnosing a diagnostic target transmitted to and received from a diagnostic tool (S11: YES), in step S12, the relay device determines whether a communication path of the received diagnostic data DD is correct. In step S13, the relay device sends a monitoring result MR including a determination result of whether a communication path of the received diagnosis data DD is correct or not to the diagnostic target device.SELECTED DRAWING: Figure 2 【課題】不正アクセスを防止したうえで、処理負荷が無用に高くなることを抑制する。【解決手段】中継装置が診断ツールとの間で送受信される診断対象を診断するための診断用データＤＤを受信したとき（Ｓ１１：ＹＥＳ）、ステップＳ１２では、中継装置は、受信した診断用データＤＤの通信経路が正しいか否かを判定する。ステップＳ１３では、中継装置は、受信した診断用データＤＤの通信経路が正しいか否かの判定結果を含む監視結果ＭＲを診断対象装置へ送信する。【選択図】図２
