  • METHOD AND SYSTEM OF VEHICLE DIAGNOSTICS BASED ON KNOWN COMMUNICATION ARCHITECTURE OF THE VEHICLE
    Publication number: 20230419743
    Abstract: A vehicle diagnostic method is based on an analysis of communication signals on a vehicle having a plurality of electronic control units (ECUs). The vehicle diagnostic method includes transmitting an ECU status request signal to the vehicle and receiving a status response signal from the vehicle. The status response signal includes a first group of ECUs on the vehicle that have responded to the transmitted ECU status request signal. The method additionally includes receiving communication DTCs from the vehicle, with the communication DTCs being associated with a second group of ECUs. A primary probable cause ECU is identified by comparing the second group of ECUs to the first group of ECUs, the primary probable cause ECU being included in the second group of ECUs and not in the first group of ECUs.
