SAE J2534-1_0500定义了排放相关控制模块重新编程的直通接口要求。SAE J2534-2/X_0500文档集为SAE J2534-1_0500 API（版本05.00）规范添加了扩展，以便该API可用于SAE J2534-1_0500规范中未涵盖的功能。这些功能共同为通用标准提供了一个全面的框架，以保护车辆原始设备制造商和故障诊断仪制造商的软件投资。SAE J2534-2/X_0500直通接口无需完全符合SAE J2534-1_0500。SAE J2534-2/X_0500接口可以实现SAE J2534-2/X_0500文档集中规定的部分或全部功能。本文件必须与SAE J2534-2/RE_0500文件一起使用。

SAE J2534-1_0500 defines the pass-thru interface requirements for the reprogramming of emission related control modules.The SAE J2534-2/X_0500 document set adds extensions to the SAE J2534-1_0500 API (version 05.00) specification so that the API can be used for features not covered in the SAE J2534-1_0500 specification. Together, these features provide a comprehensive framework for a common standard, to protect the software investment of the vehicle OEMs and scan tool manufacturers. There is no required for an SAE J2534-2/X_0500 pass-thru interface to be fully compliant with SAE J2534-1_0500. SAE J2534-2/X_0500 interfaces can implement some or all of the features specified in the SAE J2534-2/X_0500 document set.This document must be used in conjunction with the SAE J2534-2/RE_0500 document.
