- Scope
- SAE J1979-3 describes the communication between the zero emissions propulsion systems and test equipment required by government regulations. Standardization regulations require passenger cars and light-, medium-, and heavy-duty trucks to support a minimum set of diagnostic information to external (off-board) “generic” test equipment. To achieve this, SAE J1979-3 is based on the Open Systems Interconnection (OSI) Basic Refer to Model in accordance with ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.
