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, the system comprising at least a diagnosis plug-in device (1) connected to the diagnosis plug (8) of a vehicle, a host server (2), one or more on-board ECUs (3), the method comprising the following steps: /a/ detect a Bus Active condition, either via an electrical pin on the diagnosis plug or via an analysis of activity level on at least one Diagnosis bus accessible at the diagnosis plug, /b/ cause the diagnosis plug-in device to listen only on the at least one Diagnosis bus after the Bus Active condition is detected, /c/ determine a write enable condition, according to evolution of bus load level on the at least one diagnosis bus and/or after a certain time elapsed since Bus Active condition was true, /e/ whenever the write enable condition becomes true, carry out the request/answer services to write requests on the diagnosis bus and retrieve, in the corresponding answers, various data from the board ECUs (3), to be decoded and forwarded to a client fleet management system,
