# Foreword
>ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 31, Data communication.
ISO 13400 consists of the following parts, under the general title Road vehicles — Diagnostic communication over Internet Protocol (DoIP):
— Part 1: General information and use case definition

— Part 4: Ethernet-based high-speed data link connector
The following parts are under preparation:
— Part 3: Wired vehicle interface based on IEEE 802.3
# Introduction
Vehicle diagnostic communication has been developed, starting with the introduction of the first legislated emission-related diagnostics and has evolved over the years, now covering various use cases ranging from emission-related diagnostics to vehicle manufacturer specific applications like calibration or electronic component software updates.
With the introduction of new in-vehicle network communication technologies, the interface between the vehicle’s electronic control units and the external test equipment has been adapted several times to address the specific characteristics of each new network communication technology requiring optimized data link layer definitions and transport protocol developments in order to make the new in-vehicle networks usable for diagnostic communication.
With increasing memory size of electronic control units and the demand to update this increasing amount of software and an increasing number of functions provided by these control units, technology of the connecting network and buses has been driven to a level of complexity and speed similar to computer networks. New applications (x-by-wire, infotainment) require high band-width and real time networks (like FlexRay, MOST), which cannot be adapted anymore to be the direct interface to a vehicle.
This requires gateways to route and convert messages between the in-vehicle networks and the vehicle interface to external test equipment.
The intent of the ISO 13400 series is to describe a standardized vehicle interface which
— separates in-vehicle network technology from the external test equipment vehicle interface requirements to allow for a long-term stable external vehicle communication interface,
— utilizes existing industry standards to define a long-term stable state-of-the-art communication standard usable for legislated diagnostic communication, as well as for manufacturer specific use cases, and
— can easily be adapted to new physical and data link layers by using existing adaptation layers.
To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.
When mapped on this model, the services specified by ISO 14229 series are divided into:
— unified diagnostic services (layer 7), specified in ISO 14229-1, ISO 14229-5, ISO 27145-3;
— presentation (layer 6):
— for enhanced diagnostics, specified by the vehicle manufacturer;
— for WWH-OBD, specified in ISO 27145-2, SAE J1930-DA, SAE J1979-DA, SAE J2012-DA;
— session layer services (layer 5), specified in ISO 14229-2;
— transport protocol (layer 4), specified in ISO 13400-2;
— network layer (layer 3) services, specified in ISO 13400-2;
— physical and data link services (layers 1 and 2), specified in ISO 13400-3
in accordance with Table 1.

The application layer services covered by ISO 14229-5 have been defined in compliance with diagnostic
services established in ISO 14229-1, but are not limited to use only with them.
The transport and network layer services covered by ISO 13400-2 have been defined to be independent of the physical layer implemented.
For other application areas, ISO 13400-3 can be used with any Ethernet physical layer.

Protocol (DoIP) — Part 4: Ethernet-based high-speed data link connector
# 1 Scope
>This part of ISO 13400 specifies a minimum set of diagnostic Ethernet connector requirements which are based on ISO 15031-3. The ISO 15031-3 diagnostic connector is referenced by legislation in many countries.
The diagnostic connection specified in this part of ISO 13400 consists of two mating connectors: the vehicle connector and the external test equipment connector as specified in ISO 15031-3.
This part of ISO 13400 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 (2) different connector layouts and pin-outs are specified in this part of ISO 13400:
a) Ethernet pin assignment option 1 (see Annex A);
b) Ethernet pin assignment option 2 (see Annex B);
