ISO 15031-1 provide

18、s an introduction to the series of International Standards. ISO 15031-2 through ISO 15031-7 are based on Society of Automative Engineers (SAE) recommended practices. This part of ISO 15031 is based on SAE J2186:1996, E/E Data Link Security.The ISO 15031 document set includes the communication betwee

19、n the vehicles On-Board Diagnostics (OBD) systems and test equipment implemented across vehicles within the scope of the legislated emissions-related OBD.To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model in accordance with ISO/IEC 7498-1 and ISO/IEC 10731,

20、which structures communication systems into seven layers. When mapped on this model, the services specified by ISO 15031 are broken into the following: Diagnostic services (layer 7), specified in: ISO 15031-5 (emissions-related OBD); ISO 27145-3 (WWH-OBD); Presentation layer (layer 6), specified in:
