SAE J1979\/ISO 15031-5 set includes the communication between the vehicle\u2019s OBD systems and test equipment implemented across vehicles within the scope of the legislated emissions-related OBD.<\/div>\n
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, which structures communication systems into seven layers. When mapped on this model, the services specified are broken into:<\/div>\n
