1 range. This document specifies the basic requirements for Ethernet diagnostic connectors based on ISO 15031-3.
The diagnostic connection specified in this document consists of two mating connectors: the connector for the vehicle and the external diagnostic device as specified in ISO 15031-3.
This document provides:
Functional requirements for vehicle connectors, which are divided into two main areas: connector terminal definition and electrical requirements for connector-related circuitry.
Functional requirements for connectors for external test equipment, which are divided into two main areas: connector terminal definition and electrical requirements for connector-related circuitry.
This document specifies two different connector layouts and pinouts;
Ethernet Pin Assignment Scheme 1;
Ethernet Pin Assignment Scheme 2.
Scheme 1 was previously prescribed to meet the Ethernet pinout assignments of road vehicles already on the market to resolve conflicts with vehicle manufacturer's custom pins, such as pins 1 and 9.
Scheme 2 is specified to meet the Ethernet pinout for road vehiclesUsed to resolve conflicts with the vehicle manufacturer's custom pins, such as pins 3 and 11.
ISO 13400-3 specifies methods for discovery, identification, and activation of vehicle Ethernet via "Ethernet activation lines" This document applies to the design and use of 100BASE-TX Ethernet-based diagnostic connectors.

3Terms and Definitions, Abbreviations.
3,1 Terms and Definitions.
The following terms and definitions apply to this document.
Connection
Two matching connectors (31.2) or terminal (3.)1.3)。
Connector connector
Terminals (3.)1.3) and the assembly of the housing, terminating the conductor to achieve connection and disconnecting the appropriate mating connection (3.)1.1) Purpose.
Terminal contact
Connectors (3.)1.2) (a device containing a cable attachment), paired with the corresponding element to provide an electrical path.
Female contact
Used to establish an electrical connection on its inner surface and to accept the plug terminals (31.5) enter, thus forming an electrical connection (3.)1.1) of the electrical terminals (31.3) (device containing cable attachment).
Example Lake;Sockets, sheaths.
Plug terminal male contact
Electrical terminals (3.)1.3) (a device containing a cable attachment) is used to establish an electrical connection on its outer surface and enters the socket terminal (3.)1.4), thus forming an electrical connection (31,1).
Examples: splices, latches, blades.
3.2 Abbreviations.
The following acronyms apply to this document.
4. Convention. ISO 13400 (all parts) is based on the conventions applicable to diagnostic services discussed in the OSI Services Convention (see ISO IEC 10731).
5 connector requirements.
5.1 General requirements.
Vehicle manufacturers of road vehicles can choose from two different connector layouts and pinouts to meet the on-board electrical architecture design.
Discovery Identifying the vehicle Ethernet scheme (configuration) is a requirement for external test equipment in order to properly connect to Ethernet without causing any damage to the vehicle or external test equipment bus circuits. In addition, bus interference such as bus errors should be avoided.
The external test device's solution for identifying the vehicle Ethernet is based on reading the vehicle identification signal provided by the "Ethernet activation line" available on the diagnostic connector, enabling a multiplexer switch to establish an electrical connection to the vehicle Ethernet.
5.2Normative reference to ISO15031-3.
This document specifies support the additional requirements of ISO 13400-2 and S 13400-3 when accessed by diagnostic connectors that meet ISO 15031-3.
5.3Specific requirements for Ethernet.
Appendix A specifies the Ethernet connector layout pin assignment information and simplified test equipment circuit examples for Ethernet Scheme 1Appendix B specifies the Ethernet connector layout pin assignment information and simplified test equipment circuit examples for Ethernet Scheme 2.
Appendix A Ethernet Pinout Scheme 1
a.1 Overview.
This appendix describes the use of Ethernet 100BASE-TX on existing ISO 15031-3 SAE J1962 diagnostic connectors, taking into account EEE 802,3 signal requirements. All definitions in this appendix are prescriptive and facilitate the use of Ethernet for diagnostic communication in existing vehicle network architectures. This scheme can be used to resolve conflicts with vehicle manufacturer custom pins (e.g., pins 1 and 9) and the detailed specifications for the Ethernet pinout configuration are defined in ISO 15031-3 (Pinouts, Identification, and Activation Communications) and in this document (Ethernet Pinouts).

b.1 Overview.
This appendix describes the consideration of EEE 802 on existing SO15031-3 SAE J1962 diagnostic connectors3 Signal requires Ethernet 100base-tx. All definitions in this appendix are prescriptive and facilitate the use of Ethernet for diagnostic communication in existing vehicle network architectures. This scenario can be used to resolve conflicts with vehicle manufacturer custom pins, such as pins 3 and 11. The detailed specification for the Ethernet pinout configuration is defined in S 15031-3 (Pinout Identification and Activation Communication) and in this document (Ethernet Pinout).
