What ISO 15031 Series - Road Vehicles: Communication Between Vehicle and External Equipment for Emissions-Related Diagnostics (OBD) requires

ISO 15031 is a multi-part series (Parts 1 to 7), published by ISO Technical Committee TC 22 in cooperation with SAE, that specifies how external test equipment communicates with a road vehicle's on-board diagnostic (OBD) system to retrieve emissions-related diagnostic information. It is NOT a single ISO/IEC document and IEC is not a co-publisher. The series is structured by part, not by physical/data-link/application clauses: Part 1 covers general information and use cases; Part 2 terms and abbreviations; Part 3 the diagnostic connector and electrical circuits (technically equivalent to SAE J1962); Part 4 external test equipment; Part 5 emissions-related diagnostic services (the J1979/ISO 15031-5 service set); Part 6 diagnostic trouble code (DTC) definitions (referencing SAE J2012-DA); and Part 7 data link security. It applies to vehicle and diagnostic-tool manufacturers seeking standardized, interoperable access to legislated emissions OBD data.
