This document specifies ePTI-relevant system identifiers, data identifiers, routine identifiers, input/output control identifiers, data types, CompuMethods (computations), and units. This document describes ePTI systems' data definitions and associated technical requirements. The technical requirements of data definitions of emissions-related systems are specified in other standards, e.g. the ISO 15031 series[4], the ISO 27145 series[5], and SAE J1979DA. The ePTI system list defined in this document summarizes ePTI-relevant systems and specifies a defined name (system), a unique identifier (ePTI system identifier) and a description for each ePTI-relevant system. This document does not specify any type of test method or pass/fail criteria of the ePTI-relevant system during a PTI.

Abstract

Overview

ISO 20730-3:2021 - "Road vehicles - Vehicle interface for electronic Periodic Technical Inspection (ePTI) - Part 3: Data definitions" defines the standardized data vocabulary for electronic periodic technical inspection (ePTI). The document specifies ePTI system identifiers, data identifiers (DIDs), routine identifiers (RIDs), input/output control identifiers (IOIDs/IOCTs), data types, CompuMethods (computations), and units. It describes how ePTI-relevant systems and their data are named and represented for interoperable vehicle diagnostics and inspection interfaces. The standard is part of the ISO 20730 series and maps to the OSI model and UDS diagnostic framework.

Key topics and technical requirements

ePTI-relevant system list (Annex A): a normative list mapping a defined system name to a unique ePTI system identifier and description (e.g., braking, steering, airbags, lighting).
DID definitions (Annex B): normative definitions of data identifiers used to request or report specific vehicle data items.
RID/routine definitions (Annex C): normative routines for diagnostic actions and checks that can be invoked during ePTI.
Templates for identifier definitions (Annex D): standardized templates to propose or document new identifiers and names.
Data representation: specified data types, units, and CompuMethods to ensure consistent numeric conversion, scaling and interpretation across tools.
Reference protocols and identifiers: normative references to ISO 14229-1 (UDS), VIN structure (ISO 3779), and diagnostic annexes (SAE J1979DA).
Scope limits: ISO 20730-3 defines data semantics and technical data requirements only - it does not prescribe test methods, pass/fail criteria, or inspection procedures. Emissions-related data requirements are covered by other standards (e.g., ISO 15031 series, ISO 27145 series, SAE J1979DA).

Practical applications

Standardizes vehicle data exchanged for electronic periodic technical inspections, enabling:
- Interoperable PTI diagnostic tools and inspection equipment
- Remote or automated PTI data collection and reporting
- Consistent fleet compliance checks and telematics integrations
- Clear data mappings for OEMs, independent testers and tool vendors
Helps ensure diagnostic clients interpret DIDs, RIDs, and units consistently across vehicle makes and models.

Who should use this standard

Vehicle manufacturers (OEMs) defining ePTI data exposure
Diagnostic tool and scan-tool vendors
Periodic Technical Inspection (PTI) authorities and testing stations
Automotive software developers, telematics and fleet-management providers
Regulatory bodies and standards implementers
