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 22900-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.
ISO 22900 consists of the following parts, under the general title Road vehicles — Modular vehicle
communication interface (MVCI):
Part 1: Hardware design requirements
Part 2: Diagnostic protocol data unit application programming interface (D-PDU API)
Part 3: Diagnostic server application programming interface (D-Server API)

Introduction
ISO 22900 is applicable to vehicle electronic control module diagnostics and programming.
This part of ISO 22900 was established in order to more easily exchange software and hardware of vehicle
communication interfaces (VCIs) among diagnostic applications. It defines a generic and protocol independent
software interface towards the modular vehicle communication interface (MVCI) protocol module, such that a
diagnostic application based on this software interface can exchange the MVCI protocol module or add a new
MVCI protocol module with minimal effort. Today, the automotive after market requires flexible usage of
different protocol modules for vehicles of different brands. Many of today's protocol modules are incompatible
with regard to their hardware and software interface, such that, depending on the brand, a different protocol
module is required.
The objective of this part of ISO 22900 is to specify the diagnostic protocol data unit application programming
interface (D-PDU API) as a generic software interface, and to provide a “plug and play” concept for access
onto different MVCI protocol modules from different tool manufacturers. The D-PDU API will address the
generic software interface, the protocol abstraction, its exchangeability as well as the compatibility towards
existing standards such as SAE J2534-1 and RP1210a.
The implementation of the modular VCI concept facilitates co-existence and re-use of MVCI protocol modules,
especially in the after market. As a result, diagnostic or programming applications can be adapted for different
vehicle communication interfaces and different vehicles with minimal effort, thus helping to reduce overall
costs for the tool manufacturer and end user.
Vehicle communication interfaces compliant with ISO 22900 support a protocol-independent D-PDU API as
specified in this part of ISO 22900.
