Road vehicles — Open Test sequence eXchange format (OTX) — Part 3: Standard extensions and requirements

The Open Test sequence eXchange (OTX) Core, defined in ISO 13209-2, describes the basic structure underlying every OTX document. ISO 13209-3:2012 extends the Core by a set of additional features, using the extension mechanism rules described in ISO 13209-2. The extensions defined in ISO 13209-3:2012 comprise features which allow diagnostic communication to a vehicle's diagnostic interface, flashing, executing diagnostic jobs, controlling measurement equipment, internationalization, working with physical units, accessing the environment, communication via a human machine interface (HMI) and other utility extensions. ISO 13209-3:2012 defines the OTX extension requirements and data model specifications. The requirements are derived from the use cases described in ISO 13209-1. The data model specification aims at an exhaustive definition of all features of the OTX extensions which have been implemented to satisfy the requirements. ISO 13209-3:2012 establishes rules for the syntactical entities of each extension. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents containing extension features are to be interpreted. The syntax rules are provided by UML class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams and prose definitions.

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 13209-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.
ISO 13209 consists of the following parts, under the general title Road vehicles — Open Test sequence
eXchange format (OTX):
 Part 1: General information and use cases
 Part 2: Core data model specification and requirements
 Part 3: Standard extensions and requirements

ISO 13209-3:2012(E)
Introduction
Diagnostic test sequences are utilized whenever automotive components or functions with diagnostic abilities
are being diagnosed, tested, reprogrammed or initialised by off-board test equipment. Test sequences define
the succession of interactions between the user (i.e. workshop or assembly line staff), the diagnostic
application (the test equipment) and the vehicle communication interface as well as any calculations and
decisions that have to be carried out. Test sequences provide a means to define interactive, guided
diagnostics or similar test logic.
Today, the automotive industry mainly relies on paper documentation and/or proprietary authoring environ-
ments to document and to implement such test sequences for a specific test application. An author who is
setting up engineering, assembly line or service diagnostic test applications needs to implement the required
test sequences manually, supported by non-uniform test sequence documentation, most likely using different
authoring applications and formats for each specific test application. This redundant effort can be greatly
reduced if processes and tools support the OTX concept.
ISO 13209 proposes an open and standardized format for the human- and machine-readable description of
diagnostic test sequences. The format supports the requirements of transferring diagnostic test sequence
logic uniformly between electronic system suppliers, vehicle manufacturers and service dealerships/repair
shops.
ISO 13209-2 represents the requirements and technical specification for the fundament of the OTX format,
namely the "OTX Core". The Core describes the basic structure underlying every OTX document. This
comprises detailed data model definitions of all required control structures by which test sequence logic is
described, but also definitions of the outer, enveloping document structure in which test sequence logic is
embedded. To achieve extensibility the core also contains well-defined extension points that allow a separate
definition of additional OTX features – without the need to change the core data model.
This part of ISO 13209 extends the Core by a set of additional features, using the extension mechanism rules
described in ISO 13209-2. The extensions defined herein comprise features which allow diagnostic
communication to a vehicle's diagnostic interface, flashing, executing diagnostic jobs, controlling
measurement equipment, internationalisation, working with physical units, accessing the environment,
communication via a human machine interface (HMI) and other utility extensions.

Road vehicles — Open Test sequence eXchange format
(OTX) —
Part 3:
Standard extensions and requirements
1 Scope
This part of ISO 13209 defines the Open Test sequence eXchange (OTX) extension requirements and data
model specifications.
The requirements are derived from the use cases described in ISO 13209-1. They are listed in Clause 4.
The data model specification aims at an exhaustive definition of all features of the OTX extensions which have
been implemented to satisfy the requirements. This part of ISO 13209 establishes rules for the syntactical
entities of each extension. Each of these syntactical entities is accompanied by semantic rules which
determine how OTX documents containing extension features are to be interpreted. The syntax rules are
provided by UML class diagrams and XML schemas, whereas the semantics are given by UML activity
diagrams and prose definitions.

4 Requirements
4.1 Basic principles for requirements definition
Basic principles have been established as a guideline to define the OTX requirements:
a) OTX requirements specify the conditions that the OTX data model and format shall satisfy.
b) All stakeholders (System Suppliers, OEMs, Tool Suppliers), which offer diagnostic test procedures are
expected to implement and follow the requirements of this standard.
The content of OTX documents and the quality of the information is the responsibility of the originator.
4.2 Requirement priorities
Each of the following requirements carries a priority-attribute which can be set to SHALL or SHOULD.
 SHALL:
The requirement represents stakeholder-defined characteristics the absence of which will result in a
deficiency that cannot be compensated by other means.
 SHOULD:
If the requirement defined characteristic is not or not fully implemented in the data model, it does not
result in a deficiency, because other features in the data model can be used to circumvent this.
