道路车辆.排放相关诊断用车辆和外部设备之间的通信.第3部分:诊断连接器和相关电路:规范和使用
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.
