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).

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

11.6.2.3, Table 240, entry “memorySize”
Replace
“The memorySize shall be greater than 1.”
with
"The memorySize shall be greater than 0000 .".
12.2.2.1, Table 296, entry “#5”
Replace “Memory Selection” with “MemorySelection”.

12.2.4, Table 299, entry “31 ”
Replace
“This NRC shall be returned if the specified groupOfDTC parameter is not supported.”
with
“This NRC shall be returned if the specified groupOfDTC or MemorySelection parameter is not
supported.”.
12.3.1.1, last paragraph
Replace
“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
response shall be filled up with DTC 000000 and DTC status 00 . The client shall treat these DTCs as
16 16
not present in the response message.”
with
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 .
12.3.1.19
Replace all occurrences of “DTCExtDataRecordNumber” with “UserDefDTCExtDataRecordNumber” in

12.3.2.3, Table 318
Replace the table cell “UserDefDTCSnapshotRecordNumber” with the following two table cells:
DTCSnapshotRecordNumber
DTCSnapshotRecordNumber is a 1-Byte value indicating the number of the specific DTCSnapshot data
record requested for a client defined DTCMaskRecord via the reportDTCSnapshotByDTCNumber Sub-
Function.
DTCSnapshot data record number 00 and F0 shall be reserved for legislated purposes (e.g. VOBD).
16 16
DTCSnapshot records in the range of 01 through EF and F1 through FE shall be available for ve-
16 16 16 16
hicle manufacturer specific usage. A value of FF requests the server to report all stored DTCSnapshot
data records at once.
ISO 14229-1:2020/Amd.1:2022(E)
UserDefDTCSnapshotRecordNumber
UserDefDTCSnapshotRecordNumber is a 1-Byte value indicating the number of the specific DTCSnapshot
data record requested for a client defined DTCMaskRecord via the reportUserDefMemoryDTCSnapsho-
tRecordByDTCNumber SubFunction.
UserDefDTCSnapshot records in the range of 00 through FE shall be available for vehicle manufac-
16 16
turer specific usage. A value of FF requests the server to report all stored UserDefDTCSnapshot data
records at once.
12.3.2.3, Table 318, entry for DTCReadinessGroupIdentifier
Replace
“specifies the reference to the the DTC readiness group and associated”
