22、f a number of parts which, taken together, provide a coherent self-consistent set of specifications to facilitate emissions-related diagnostics. ISO 15031-1 provides an introduction to the series of International Standards. ISO 15031-2 through ISO 15031-7 are based on SAE recommended practices. This
23、 part of ISO 15031 is based on SAE J2012 (Diagnostic Trouble Code Definitions).This International Standard includes the communication between the vehicles On-Board Diagnostic (OBD) systems and test equipment implemented across vehicles within the scope of the legislated emissions-related OBD.To achi
24、eve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model in accordance with ISO/IEC 7498 and ISO/IEC 10731, which structures communication systems into seven layers. When mapped on this model, the services specified by this International Standard are broken into the foll
25、owing layers in accordance with Table 1. Diagnostic services (layer 7), specified in the following: ISO 15031-5 (emissions-related OBD); ISO 27145-3 (WWH-OBD).

46、d 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.This part of ISO 15031 specifies the
47、rules and guidelines for the definition of the following:a) the diagnostic trouble code format, which consists of the following:1) addressing format;2) structure;3) messages;b) a description of the standardized set of diagnostic trouble codes and descriptions contained in SAE J2012-DA. The two most
48、significant bytes of a DTC may be decoded according to two different lists in two formats: DTC Format Identifier 0016and 0416;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).This p
49、art of ISO 15031 specifies all general rules and guidelines to define new diagnostic trouble codes. This part of ISO 15031 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.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
