标准摘要
[中文适用范围]： 本推荐做法的目的是验证车辆和/或组件是否能够根据 SAE J1939-73：诊断服务中指定的诊断测试模式传送最小的信息子集。本文件描述了用于验证从车外设备到车辆和/或组件的诊断通信的测试、测试方法和结果。 [外文原描述]： The purpose of this SAE Recommended Practice is to verify that vehicles and/or components are capable of communicating a required set of information, which is described by the diagnostic messages specified in SAE J1939-73, that is in accordance with off-board diagnostic tool interface requirements contained in the government regulations cited below.This document describes the tests, methods, and results for verifying diagnostic communications from an off-board diagnostic tool (i.e., scan tool) to a vehicle and/or component. SAE members have generated this document to serve as a guide for testing vehicles for compliance with ARB and other requirements for emissions-related on-board diagnostic (OBD) functions for heavy-duty engines used in medium- and heavy-duty vehicles.The development of HD OBD regulations by U.S. EPA and California’s Air Resources Board (ARB) require that diagnostic message services are exercised to evaluate diagnostic communication standardization requirements on production vehicles. The user should reference the summary provided by SAE J1939-73 Tables 1 and 2 for OBD compliance support, and the discussion in SAE J1939-73 Appendix H for additional implementation concepts.Cross Reference: 13 CCR 1968.2,13 CCR 1971.1,ISO 3779:2009,J1699/3_201205,J1939/03_202105,J1939/11_201209,J1939/13_201110,J1939/15_201405,J1939/21_201012,J1939/71_201103,J1939/73_201307,J1939/81_201106,J1939_201104,J2403_201102,J272
