GB/T 43258.4-2023Road vehicles - Diagnostic communication over Internet Protocol (DoIP) - Part 4: Ethernet-based high-speed data link connector (English PDF)

Foreword

This document is drafted in accordance with the rules provided in GB/T 1.1-2020

Directives for standardization - Part 1: Rules for the structure and drafting of

standardizing documents.

This document is part 4 of GB/T 43258 Road vehicles - Diagnostic communication over

Internet Protocol (DoIP). The following parts have been issued for GB/T 43258:

— Part 2: Transport protocol and network layer services;

— Part 3: Wired vehicle interface based on IEEE 802.3;

— Part 4: Ethernet-based high-speed data link connector.

This document adopts ISO 13400-4:2016 Road vehicles - Diagnostic communication

over Internet Protocol (DoIP) - Part 4: Ethernet-based high-speed data link connector

by modification.

The technical differences between this document and ISO 13400-4:2016, and the causes

for these differences are as follows:

— REMOVE the reference and description of ISO 13400-1 which has been abolished.

1 Scope

This document specifies a minimum set of diagnostic Ethernet connector requirements

which are based on ISO 15031-3.

The diagnostic connection specified in this document consists of two mating connectors:

the vehicle connector and the external test equipment connector as specified in ISO

15031-3.

This document specifies:

— the functional requirements for the vehicle connector. These functional

requirements are separated into two principal areas: connector contact allocation

and electrical requirements for connector and related electrical circuits;

— the functional requirements for the external test equipment connector. These

functional requirements are separated into two principal areas: connector contact

allocation and electrical requirements for connector and related electrical circuits.

Two different connector layouts and pin-outs are specified in this document:

— Ethernet pin assignment option 1;

— Ethernet pin assignment option 2.

Historically, option 1 is specified to meet Ethernet pin assignment of road vehicles

already launched onto the market and may be used to resolve conflicts with vehicle

manufacturer-specific usage of discretionary pins, e.g. pins 1 and 9.

Option 2 is specified to meet the Ethernet pin assignment of road vehicles to resolve

conflicts with vehicle manufacturer-specific usage of discretionary pins, e.g. pins 3 and

11.

A discovery/identification and activation method of the vehicle's Ethernet via the

"Ethernet Activation Line" is specified in ISO 13400-3.

This document applies to the design and use based on 100BASE-TX diagnostic

Ethernet connector.

4 Conventions

ISO 13400 (all parts) is based on the conventions discussed in the OSI Service

Conventions (see ISO/IEC 10731) as they apply for diagnostic services.
