Full title and description

Road vehicles — Standardized access to automotive repair and maintenance information (RMI) — Part 2: Technical requirements. This part of ISO 18541 specifies the minimum technical requirements for vehicle‑manufacturer RMI systems to enable standardized, secure access to repair and maintenance information for independent operators and other authorised users.

Abstract

ISO 18541-2:2021 defines technical requirements related to automotive repair and maintenance information (RMI) systems to standardize access for independent operators. It covers the minimum set of technical requirements for a vehicle manufacturer's RMI system, aligns with the use cases in ISO 18541‑1, and includes provisions for granting access to security‑related RMI following the SERMI scheme (see Annex A). The document is applicable to light passenger and commercial vehicles as defined in Regulation (EC) 715/2007 Article 2.

Scope

Specifies the technical requirements necessary for standardised access to vehicle repair and maintenance information (RMI) held by vehicle manufacturers. The scope includes access management, IT architecture, external interfaces and technical infrastructure required to support the use cases defined in ISO 18541‑1. It also addresses requirements for granting access to security‑related RMI (SERMI) and is applicable to light passenger and commercial vehicles as defined in Regulation (EC) 715/2007 Article 2.

Key topics and requirements

• Access administration and identity/authorization mechanisms for RMI systems.
• Minimum IT architecture and systems requirements for vehicle‑manufacturer RMI services.
• Definition and standardization of external interfaces for third‑party access.
• Technical infrastructure and service availability requirements to support third‑party operators.
• Requirements and procedures for secure access to safety‑critical information (SERMI) as described in Annex A.
• Conformance and testing considerations (see related Part 4 for conformance tests).

Typical use and users

Used by vehicle manufacturers (to design and provide RMI systems), independent repairers and service providers (to access repair and maintenance information), telematics and software providers (for integration with RMI services), regulators and compliance bodies (to assess access and security provisions), and test/conformance teams implementing ISO 18541 conformance checks.
