Honda Diagnostic Serial Data Link Protocol - ABS/VSA System

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J2809_201710
  • Current
Published 2017-10-09 by SAE International in United States
This Technical Information Report defines the proprietary diagnostic communication protocol for ABS or VSA ECU (Electronic Control Unit) implemented on some Honda vehicles. This protocol does not apply to all Honda vehicles. This document should be used in conjunction with SAE J2534-2 in order to fully implement the communication protocol in an enhanced SAE J2534 interface. The purpose of this document is to specify the requirements necessary to implement the communication protocol in an enhanced SAE J2534 interface.

Vehicle OBD II Compliance Test Cases

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J1699/3_201707
  • Current
Published 2017-07-21 by SAE International in United States
The main purpose of this Recommended Practice is to verify that vehicles are capable of communicating a minimum subset of information, in accordance with the diagnostic test services specified in SAE J1979: E/E Diagnostic Test Modes, or the equivalent document ISO 15031-5: Communication Between Vehicle and External Equipment for Emissions-Related Diagnostics – Part 5: Emissions-related diagnostic services. Any software meeting these specifications will utilize the vehicle interface that is defined in SAE J2534, Recommended Practice for Pass-Thru Vehicle Programming.

Electrical/Electronic Systems Diagnostic Terms, Definitions, Abbreviations, and Acronyms - Equivalent to ISO/TR 15031-2

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J1930_201703
  • Current
Published 2017-03-07 by SAE International in United States
This SAE Recommended Practice supersedes SAE J1930 OCT2008, and is technically equivalent to ISO 15031-2. This document is applicable to all light-duty gasoline and diesel passenger vehicles and trucks, and to heavy-duty gasoline vehicles. Specific applications of this document include diagnostic, service and repair manuals, bulletins and updates, training manuals, repair databases, underhood emission labels, and emission certification applications. This document should be used in conjunction with SAE J1930DA Digital Annexes, which contains all of the information previously contained within the SAE J1930 tables. These documents focus on diagnostic terms applicable to electrical/electronic systems, and therefore also contains related mechanical terms, definitions, abbreviations, and acronyms. Even though the use and appropriate updating of these documents is strongly encouraged, nothing in these documents should be construed as prohibiting the introduction of a term, abbreviation, or acronym not covered by these documents. Certain terms have already been in common use and are readily understood by manufacturers and technicians, but do not strictly follow the methodology of this document. The SAE J1930 committee may approve these terms that…

E/E Diagnostic Test Modes

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J1979_201702
  • Current
Published 2017-02-16 by SAE International in United States
SAE J1979/ISO 15031-5 set includes the communication between the vehicle’s OBD systems and test equipment implemented across vehicles within the scope of the legislated emissions-related OBD. To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model in accordance with ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When mapped on this model, the services specified are broken into: — Diagnostic services (layer 7), specified in: — ISO 15031-5/SAE J1979 (emissions-related OBD), — ISO 27145-3 (WWH-OBD), — Presentation layer (layer 6), specified in: — ISO 15031-2, SAE J1930-DA, — ISO 15031-5, SAE J1979-DA, — ISO 15031-6, SAE J2012-DA, — ISO 27145-2, SAE J2012-DA, — Session layer services (layer 5), specified in: — ISO 14229-2 supports ISO 15765-4 DoCAN and ISO 14230-4 DoK-Line protocols, — ISO 14229-2 is not applicable to the SAE J1850 and ISO 9141-2 protocols, — Transport layer services (layer 4), specified in: — DoCAN: ISO 15765-2 Transport protocol and network layer services, — SAE J1850: ISO 15031-5/SAE J1979 Emissions-related diagnostic services, — ISO 9141-2:…

J1979-DA, Digital Annex of E/E Diagnostic Test Modes

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J1979DA_201702
  • Current
Published 2017-02-16 by SAE International in United States
On-Board Diagnostic (OBD) regulations require passenger cars, and light and medium duty trucks, to support communication of a minimum set of diagnostic information to off-board “generic” test equipment. This document specifies the diagnostic data which may be required to be supported by motor vehicles and external test equipment for diagnostic purposes which pertain to motor vehicle emission-related data. SAE J1979 was originally developed to meet U.S. OBD requirements for 1996 and later model year vehicles. ISO 15031 5 was based on SAE J1979 and was intended to combine the U.S. requirements with European OBD requirements for 2000 and later model year vehicles.
