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

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

“When using paged-buffer-handling to read DTCs (especially for SubFunction = reportDTCByStatusMask),
it is possible that the number of DTCs can decrease while creating the response. In such a case the

ISO 14229-1:2020/Amd.1:2022(E)
“The service ReadDTCInformation can result in responses that contain information
from many DTCs (such as reportDTCByStatusMask, reportDTCSnapshotIdentification,
reportDTCExtDataRecordByRecordNumber, …). With paged-buffer-handling to read DTCs it is possible
that:
— the DTC status is changing and thus the number of DTCs matching the filter is decreased; or
— the DTC is removed due to fault memory overflow and thus no more data to read is available.
In this case the response shall be filled up with DTC 000000 and statusOfDTC 00 . In case of
16 16
SubFunction reportDTCExtDataRecordByRecordNumber the DTCExtDataRecord data bytes shall be
also filled up with 00 .
