Abstract: In one aspect, a method is carried out in a system including diagnosis plug-in device, a host server, diagnostics database suppliers, and on-board ECUs, with the method including coupling the diagnosis plug-in device to the diagnosis port of a vehicle of interest having a certain vehicle type defined at least by the Make/Model/Year/Powertrain of the vehicle of interest; causing the diagnosis plug-in device to listen on a diagnosis and receiving frames broadcasted by onboard ECUs; after said Bus Active condition is detected, determining a frame profile according to characteristics of the received frame-IDs; determining vehicle type from the frame profile, with the help of a frame profile lookup table; and providing a diagnosis stacks dataset database at the diagnosis plug-in device or at the host server, said diagnosis stacks dataset comprising at least available request/answer services for the vehicle type of interest.

Abstract: A method carried out in a system comprising a Diagnosis plug-in device (1) a host server (2), diagnostics database suppliers (4), on-board ECUs (3), the method comprising: /a/ couple the diagnosis plug-in device to the diagnosis port (8) of a vehicle of interest, said vehicle of interest having a certain vehicle type, said vehicle type being defined at least by the Make/Model/Year/Powertrain of the vehicle of interest, /b/ cause the diagnosis plug-in device to listen on a diagnosis, receive frames broadcasted by onboard ECUs and detect therefrom a Bus Active condition, /c/ after said Bus Active condition, determine a frame profile according to characteristics of the received frame-IDs, /d1/ determine vehicle type from the frame profile, with the help of a frame profile lookup table (22,22a) held in the diagnosis plug-in device (1) and/or in the host server (2), /e/ provide a diagnosis stacks dataset database (23) at the diagnosis plug-in device (1) and/or at the host server (2), comprising, for each record
