[7]
EC [replaced by (EU) 167/2013 ] and, in particular, to requirements for access to vehicle repair and
maintenance information by independent operators.
The purpose of the EC Mandate M/421 is to develop a standard or set of standards which specify the
requirements to provide standardized access to automotive repair and maintenance information (RMI)
for independent operators.
The ISO 18541 series only covers access to automotive repair and maintenance information for
[15] [14]
light passenger and commercial vehicles [see (EC) No 715/2007 , (EC) No 692/2008 and

(EU) No 566/2011 ] and heavy-duty vehicles [see (EC) No 595/2009 , (EU) No 582/2011
[9] [8]
and (EU) No 64/2012 ] based on Directive 2007/46/EC and for two-or three-wheel vehicles and
[6]
quadricycles based on regulation (EU) 168/2013 .
The information included in the ISO 18541 series derives from the legislative requirements on European
level in the field of RMI and related security requirements and can be referenced by legislation in other
countries.

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

Part 1:
General information and use case definition
1 Scope
This document provides a general overview and structure of each part of ISO 18541. This document also
describes the use cases applicable to the standardized access to automotive RMI. The use cases address
real world scenarios (e.g. servicing vehicles) regarding the information access necessary to perform
vehicle roadside assistance, inspection, diagnosis, repair and maintenance, including the updating and
replacement of Electronic Control Units (ECU).
Furthermore, this document defines requirements for granting access to security-related RMI in
Annex A following the SERMI scheme.
The RMI systems used by personnel to perform the services consist of:
— a web-based system, which provides access to RMI needed to perform the service(s);
— contact information for specific RMI;
— a security framework to protect access to security-related RMI (vehicle theft protection measures).
This document is applicable to light passenger vehicle and light commercial vehicles.
