Regulation (EU) 2018/858 of the European Parliament and of the Council of 30 May 2018 on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles, amending Regulations (EC) No 715/2007 and (EC) No 595/2009 and repealing Directive 2007/46/EC (Text with EEA relevance)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
Point in time view as at 31/01/2020.
Regulation (EU) 2018/858 of the European Parliament and of the Council, Appendix 2 is up to date with all changes known to be in force on or before 27 August 2024. There are changes that may be brought into force at a future date. Changes that have been made appear in the content and are referenced with annotations.
Changes and effects yet to be applied by the editorial team are only applicable when viewing the latest version or prospective version of legislation. They are therefore not accessible when viewing legislation as at a specific point in time. To view the ‘Changes to Legislation’ information for this provision return to the latest version view using the options provided in the ‘What Version’ box above.
a description of the type and number of the preconditioning cycles used for the original type-approval of the vehicle;
a description of the type of the OBD demonstration cycle used for the original type-approval of the vehicle for the component monitored by the OBD system;
a comprehensive document describing all sensed components with the strategy for fault detection and MI activation (fixed number of driving cycles or statistical method), including a list of relevant secondary sensed parameters for each component monitored by the OBD system and a list of all OBD output codes and format used (with an explanation of each code and format) associated with individual emission-related power-train components and individual non-emission related components, where monitoring of the component is used to determine MI activation. In particular, in the case of types of vehicles that use a communication link in accordance with ISO 15765-4 ‘Road vehicles — Diagnostics on controller area network (CAN) — Part 4: Requirements for emissions-related systems’, a comprehensive explanation for the data given in service $ 05 Test ID $ 21 to FF and the data given in service $ 06, and a comprehensive explanation for the data given in service $ 06 Test ID $ 00 to FF, for each OBD monitor ID supported, shall be provided.
In case other communication protocols standards are used, equivalent comprehensive explanation shall be provided.
This information may be provided in the form of a table, with the following column and row headings:
Component Fault code; Monitoring strategy; Fault detection criteria; MI activation criteria; Secondary parameters; Preconditioning Demonstration test.
Catalyst P0420 Oxygen sensor; 1 and 2 signals; Difference between sensor 1 and sensor 2 signals; 3rd cycle Engine speed; engine load; A/F mode; catalyst temperature; Two Type 1 cycles; Type 1.
In order to facilitate the provision of generic diagnostic tools for multi-make repairers, vehicle manufacturers shall make available the information referred to in points 3.1, 3.2 and 3.3 through their repair information websites. That information shall include all diagnostic tool functions and all the links to repair information and troubleshooting instructions. The access to the information may be subject to the payment of a reasonable fee.
The following information shall be required indexed against vehicle make, model and variant, or another workable definition such as the VIN or the vehicle and systems identification:
any additional protocol information system necessary to enable complete diagnostics in addition to the standards prescribed in paragraph 4.7.3 of Annex 9B to UN Regulation No 49 and in paragraph 6.5.1.4 of Annex 11 to UN Regulation No 83, including any additional hardware or software protocol information, parameter identification, transfer functions, ‘keep alive’ requirements, or error conditions;
details of how to obtain and interpret all the fault codes that do not comply with the standards prescribed in paragraph 4.7.3 of Annex 9B to UN Regulation No 49 and in paragraph 6.5.1.4 of Annex 11 to UN Regulation No 83;
a list of all available live data parameters, including scaling and access information;
a list of all available functional tests, including device activation or control and the means to implement them;
details of how to obtain all component and status information, time stamps, pending DTC and freeze frames;
resetting adaptive learning parameters, variant coding and replacement component setup, and customer preferences;
Electronic control unit (ECU) identification and variant coding;
details of how to reset service lights;
location of diagnostic connector and connector details;
engine code identification.
The following information shall be required:
a description of tests to confirm the functionality, at the component or in the harness;
information concerning the test procedure, including test parameters and component information;
connection details, including minimum and maximum input and output and driving and loading values;
values to be expected under certain driving conditions, including idling;
electrical values for the component in its static and dynamic states;
failure mode values for each of the scenarios;
failure mode diagnostic sequences, including fault trees and guided diagnostics elimination.
The following information shall be required:
ECU and component initialisation (in the event of replacements being fitted);
initialisation of new or replacement ECU's where relevant using pass-through (re-) programming techniques.

This timeline shows the different versions taken from EUR-Lex before exit day and during the implementation period as well as any subsequent versions created after the implementation period as a result of changes made by UK legislation.
The dates for the EU versions are taken from the document dates on EUR-Lex and may not always coincide with when the changes came into force for the document.
For any versions created after the implementation period as a result of changes made by UK legislation the date will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
