标准摘要
[中文适用范围]： 本文档引用了 SAE J1962 的最新出版物。 车载诊断 (OBD) 法规要求道路车辆配备标准化连接器，以便通过外部测试设备访问 OBD 信息。 本文档描述了物理连接和相关引脚使用的要求，以允许对 OBD 数据进行标准访问。 本文件在技术上等同于 SAE J1962，但所确定的具体要求以及与右手驾驶 (RHD) 车辆相关的附加要求规范除外。 [外文原描述]： This document references the latest publication of SAE J1962. On-board diagnostic (OBD) regulations require road vehicles to be equipped with a standardized connector for purposes of access to OBD information by external test equipment. This document describes the requirements for the physical connection and associated pin usage to allow for standard access to the OBD data. This document is technically equivalent to SAE J1962 with the exception of the specific requirements identified and the specification of additional requirements related to right hand driven (RHD) vehicles.
