本SAE推荐规程是SAE J2534-2/X_0500系列文件的一部分，该系列文件扩展了SAE J2534-1_0500 API（版本05.00）规范，并定义了如何在SAE J2534 API框架内实现容错CAN（FT CAN）。本文件仅详述了SAE J2534-1_0500的变更，本文件中未具体详述的项目假定未发生变更。SAE J2534-2/8_0500接口只有在实现了本SAE推荐规程中所有要求的功能时，才应符合容错CAN（FT CAN）功能。合规性不需要的任何功能将在本文件中明确标记为“可选”。本文件必须与SAE J2534-2/BA_0500和SAE J2534-2/RE_0500文件一起使用。

This SAE Recommended Practice is part of the SAE J2534-2/X_0500 set of documents that extends the SAE J2534-1_0500 API (version 05.00) specification, and defines how to implement fault-tolerant CAN (FT CAN) within the SAE J2534 API framework. This document details only the changes from SAE J2534-1_0500 and items not specifically detailed in this document are assumed to have not changed.An SAE J2534-2/8_0500 interface shall be compliant to fault-tolerant CAN (FT CAN) feature only when all the required functionality in this SAE Recommended Practice is implemented. Any functionality not required for compliance will be specifically marked as ¿¿¿optional¿¿¿ in this document.This document must be used in conjunction with the SAE J2534-2/BA_0500 and SAE J2534-2/RE_0500 documents.
