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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 13400-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical
and electronic equipment.
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 2: Transport protocol and network layer services
— Part 3: Wired vehicle interface based on IEEE 802.3
The following parts are under preparation:
— Part 4: Ethernet diagnostic connector

ISO 13400-3:2011(E)
Introduction
Vehicle diagnostic communication has been developed starting with the introduction of the first legislated
emissions-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 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, 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 to provide the direct interface to a vehicle. This requires gateways to route and
convert messages between the in-vehicle networks and the vehicle interface to test equipment.
The intent of ISO 13400 (all parts) 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, including wired and wireless connections, by
using existing adaptation layers.
To achieve this, all parts of ISO 13400 are 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 14229-1, ISO 14229-2 and ISO 14229-5
are divided into
a) unified diagnostic services (layer 7), specified in ISO 14229-1, ISO 14229-5, ISO 27145-3,
b) presentation (layer 6):
1) for enhanced diagnostics, specified by the vehicle manufacturer,
2) for WWH-OBD (World-Wide Harmonized On-Board Diagnostics), specified in ISO 27145-2,
SAE J1930-DA, SAE J1939:2011, Appendix C (SPNs), SAE J1939-73:2010, Appendix A (FMI),
SAE J1979-DA, SAE J2012-DA,
c) session layer services (layer 5), specified in ISO 14229-2,
d) transport protocol (layer 4), specified in ISO 13400-2,
e) network layer (layer 3) services, specified in ISO 13400-2, and
f) physical and data link services (layers 1 and 2), specified in this part of ISO 13400,
in accordance with Table 1.

1 Scope
This part of ISO 13400 specifies the vehicle communication interface and test equipment requirements for a
physical and data link layer based on IEEE 802.3 100BaseTx.
This interface serves as the physical basis for IP-based communication between the vehicle and test equipment.
This part of ISO 13400 specifies the following aspects:
— requirements for signal and wiring schematics in order to ensure physical layer compatibility of the vehicle
interface and Ethernet networks and test equipment communication interfaces;
— activation and deactivation of the diagnostic Ethernet interface;
— mechanical and electrical diagnostic connector requirements.

apply to diagnostic services.
5 Document overview
ISO 13400 is applicable to vehicle diagnostic systems implemented on an IP communication network.
ISO 13400 has been established in order to define common requirements for vehicle diagnostic systems
implemented on an IP communication link.
Although primarily intended for diagnostic systems, ISO 13400 has been developed to also meet requirements
from other IP-based systems needing a transport protocol and network layer services.
Figure 1 illustrates the most applicable application implementations utilizing DoIP.

6 Ethernet physical and data link layer requirements
6.1 General information
Ethernet is a collection of several standards for different transmission technologies and speeds contained in
IEEE 802.3 and is a frame-based networking technology for wired local area networks. Frames are defined
as the format of data packets on the wire. The Internet Protocol (IPv4) theoretically allows for a maximum IP
packet length of 64 Kbytes. This size is limited by the Ethernet specification, which defines a 16-bit-length
field and requires a minimum packet length of 64 bytes as well as allowing for a maximum payload length of
1 500 bytes. Consequently, IP packets can have a maximum length of only 1 500 bytes on Ethernet. However,
IP allows for fragmentation of IP packets over multiple Ethernet frames to work around this limitation. The rules
for fragmentation of IP packets differ between IPv6 and IPv4 and are not specified in this part of ISO 13400.
