标准摘要
[中文适用范围]： 本部分 ISO 15031 提供了统一的标准诊断故障码（DTC），要求机动车的电子/电气车载诊断（OBD）系统在检测到故障时进行报告。它还提供了与这些代码相关的统一消息（文本描述符）的指导。本部分规定了以下定义规则和指南：a) 诊断故障码格式，包括寻址格式、结构和消息；b) SAE J2012-DA 中包含的标准诊断故障码集合及其描述。DTC 的两个最高有效字节可以根据两个不同的列表以两种格式进行解码：DTC 格式标识符 0016 和 0416；c) 已知为故障类型（failure types）的标准诊断故障码子集的描述（仅在使用 3 字节 DTC 时适用）。本部分规定了定义新诊断故障码的所有通用规则和指南。 [外文原描述]： ISO 15031-6:2015 provides uniformity for standardized diagnostic trouble codes (DTC) that electrical/electronic On-Board Diagnostic (OBD) systems of motor vehicles are required to report when malfunctions are detected. It further provides guidance for uniform messages (text descriptor) associated with these codes. ISO 15031-6:2015 specifies the rules and guidelines for the definition of the following: a) the diagnostic trouble code format, which consists of addressing format, structure and messages; b) a description of the standardized set of diagnostic trouble codes and descriptions contained in SAE J2012-DA. The two most significant bytes of a DTC may be decoded according to two different lists in two formats: DTC Format Identifier 00 16 and 04 16 ; and c) a description of the standardized set of diagnostic trouble codes subtypes known as failure types contained in SAE J2012-DA (applies only when 3-byte DTCs are used). ISO 15031-6:2015 specifies all general rules and guidelines to define new diagnostic trouble codes. It references SAE J2012-DA (Digital Annex), which includes all standardized DTCs (number and text descriptor) as well as all diagnostic trouble codes subtypes known as failure types.
