  • Publication number: 20240176720
    Abstract: A communication system includes a relay device and a diagnosis target device. The relay device includes a port configured to connect a diagnostic tool. The diagnosis target device is connected to the relay device via a bus. When the diagnosis target device has received specific data whose source appears to be the diagnostic tool, the diagnosis target device sends an inquiry signal for inquiring of the relay device about a monitoring result for the specific data. The relay device determines in response to the inquiry signal whether the specific data is legitimate data from the diagnostic tool. The relay device sends the monitoring result including a determination result to the diagnosis target device.
