The invention provides a communication system and a relay device. The communication system includes a relay device and a diagnosis subject device. The relay device includes a port configured to connect a diagnostic tool. The device to be diagnosed is connected to the relay device via a bus. When the relay device has received diagnostic data for diagnosing the device to be diagnosed, the relay device determines whether or not a communication path of the diagnostic data is correct, the diagnostic data being data transmitted between the relay device and the diagnostic tool. The relay device transmits, to the device to be diagnosed, a monitoring result including a result of determining whether or not the communication path of the diagnostic data is correct. 本公开提供通信系统和中继装置。所述通信系统包括中继装置和诊断对象装置。所述中继装置包括配置为连接诊断工具的端口。所述诊断对象装置经由总线连接至所述中继装置。当所述中继装置已经接收到用于诊断所述诊断对象装置的诊断数据时，所述中继装置判定所述诊断数据的通信路径是否正确，所述诊断数据为在所述中继装置与所述诊断工具之间传输的数据。所述中继装置向所述诊断对象装置发送包括关于所述诊断数据的所述通信路径是否正确的判定结果的监控结果。
