- Content
- This SAE Recommended Practice describes the implementation of Enhanced Diagnostic Test Modes, which are intended to supplement the legislated Diagnostic Test Modes defined in SAE J1979. Modes are defined for access to emission related test data beyond what is included in SAE J1979, and for non-emission related data. This document describes the data byte values for diagnostic messages transmitted between diagnostic test equipment, either on-vehicle or off-vehicle, and vehicle electronic control modules. No distinction is made between test modes for emission related and non-emission related diagnostics. These messages can be used with a diagnostic serial data link such as described in SAE J1850 or ISO 9141-2. For each test mode, this document includes a functional description of the test mode, request and report message data byte content, and an example if useful for clarification.
- Content
- This has not been superseded by any later SAE documents, but has been superseded by some ISO documents, which at a very high level include information that was in SAE J2190, but go into considerably more detail. ISO 14230-3:1999 is intended for ISO 14230 (ISO 9141 based) serial data links, ISO 15765-3:2004 is intended for ISO 15765 (CAN) data links, and ISO 14229-1:2006 is "Unified Diagnostic Services" intended for all current and future serial data links.
