scope:

ISO 18541 is structured into four parts: - Part 1: General information and use case definition - Part 2: Technical requirements - Part 3: Functional user interface requirements - Part 4: Conformance test This part of the standard includes "General Information" which provides a general overview and structure about each part of the standard. It also specifies "Use Cases" related to Repair and Maintenance Information (RMI) systems in order to standardize the access to RMI for independent operators. This part of the standard also describes the use cases applicable to the standardized access to automotive RMI. The use cases address real world scenarios when e.g. servicing vehicles in regard to information access necessary to perform vehicle roadside assistance, inspection, diagnosis, repair and maintenance, including updating and replacement of Electronic Control Units (ECU). 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); - provides contact information for specific RMI; - a security framework to protect access to security related RMI; Reading part 1 of this standard will provide an overview about the entire standard and how it applies to the automotive industry. This part of ISO 18541 is applicable to light passenger and commercial vehicles as defined in regulation (EC) 715/2007 Article 2 [5]. ISO 18542 is a complementary standard that defines the 'Standardized RMI terminology' and consists of two parts: - Part 1: General information and use case definition - Part 2: Standardized process implementation requirements and Registration Authority The standardized RMI terminology is contained in a so-called 'Digital Annex'.
