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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 31,
Data communication.
This third edition cancels and replaces the second edition (ISO 16844-7:2015), which has been
technically revised.
The main changes are as follows:
— part 5 of this series (ISO 16844-5) has been removed due to its technical irrelevance,
— correction of the typos and mistakes in the text,
— adoption of the content according to the new version of the ISO guidelines,
— adoption of the content according to the new technical requirements,
— alignment of the content regarding to the referred standards.
A list of all parts in the ISO 16844 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document supports and facilitates the communication between electronic control units (ECUs)
and a digital tachograph.
The digital tachograph concept is based upon a recording equipment storing data, related to the
activities of the various drivers driving the vehicle, on which it is installed.
During the normal operational status of the recording equipment, data stored in its memory are
accessible to different entities (drivers, authorities, workshops, transport companies) in different ways
(displayed on a screen, printed by a printing device, downloaded to an external device). Access to stored
data are controlled by a smart card inserted in the tachograph.
A typical tachograph system is shown in Figure 1.
