Full title and description

Road vehicles — Standardized access to automotive repair and maintenance information (RMI) — Part 1: General information and use case definition. ISO 18541-1:2021 provides the overall structure for the ISO 18541 series and defines the RMI use cases and principles that guide standardized access to vehicle repair and maintenance information, including requirements for controlled access to security-related RMI (SERMI scheme).

Abstract

This part of ISO 18541 gives a general overview of the series and describes the real‑world use cases (roadside assistance, inspection, diagnosis, repair, maintenance, ECU update/replacement) for standardized access to automotive repair and maintenance information (RMI). It specifies the RMI system components (web‑based access, contact information, security framework) and defines requirements for granting access to security‑related RMI in Annex A, following the SERMI scheme. The document is applicable to light passenger and light commercial vehicles.

Scope

ISO 18541-1:2021 defines the scope, structure and use‑case definitions for the ISO 18541 family that standardizes access to manufacturer RMI. It covers the information access needs for personnel performing vehicle services including roadside assistance, inspection, diagnosis, repair and maintenance and the updating/replacement of electronic control units. The part also addresses controlled access to security‑related RMI via the SERMI scheme. The standard is intended for light passenger and light commercial vehicles.

Key topics and requirements

• Overview and structure of the ISO 18541 series and how parts interrelate.
• Detailed use‑case definitions for RMI access (servicing, inspection, diagnosis, repair, maintenance, ECU update/replacement).
• Specification of RMI system components: web‑based access portals, contact information management, and security framework requirements.
• Requirements and principles for granting access to security‑related RMI, following the SERMI scheme (Annex A).
• Applicability and constraints for light passenger and light commercial vehicles (referencing relevant regulatory definitions).
• Foundational input for the technical requirements (Part 2), UI requirements (Part 3) and conformance testing (Part 4).

Typical use and users

Typical users include vehicle manufacturers and their RMI system providers, independent repairers and aftermarket service organisations, diagnostic tool and telematics vendors, fleet operators, authorised workshops, regulators and conformity assessors. The standard is used when specifying RMI services, designing access and security models, and preparing conformance tests for RMI systems.

Related standards

ISO 18541 is a multipart series. Closely related parts (second edition, 2021) include: Part 2 — Technical requirements; Part 3 — Functional user interface requirements; Part 4 — Conformance test. Earlier (2014/2015) first‑edition parts were withdrawn and superseded by these 2021 editions. ISO/TC 22/SC 31 is the technical committee responsible for the series.

Q: What does it cover?

A: It covers the overall structure of the series, RMI use cases (servicing, roadside assistance, inspection, diagnosis, repair, maintenance, ECU updates/replacement), RMI system components and access control principles for security‑related RMI (SERMI).

Q: Who typically uses it?

A: Vehicle manufacturers, RMI system providers, independent repair shops, diagnostic tool vendors, fleet managers, and regulators use it to design, implement and assess standardized RMI access.
