Textual Amendments

F1 Inserted by Commission Regulation (EU) No 64/2012 of 23 January 2012 amending Regulation (EU) No 582/2011 implementing and amending Regulation (EC) No 595/2009 of the European Parliament and of the Council with respect to emissions from heavy duty vehicles (Euro VI) (Text with EEA relevance).

Vehicle OBD information U.K.

1. The information required in this Appendix shall be provided by the vehicle manufacturer for the purposes of enabling the manufacture of OBD-compatible replacement or service parts and diagnostic tools and test equipment. U.K.

2. Upon request, the following information shall be made available to any interested component, diagnostic tools or test equipment manufacturer, on a non-discriminatory basis: U.K.

• 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 vehicle types 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, as follows:

• 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 |

3. Information required for the manufacture of diagnostic tools U.K.

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.

3.1. Communication protocol information U.K.

The following information shall be required indexed against vehicle make, model and variant, or other workable definition such as VIN or vehicle and systems identification:

(a)

Any additional protocol information system necessary to enable complete diagnostics in addition to the standards prescribed in Point 4.7.3 of Annex 9B to UN/ECE Regulation No 49, including any additional hardware or software protocol information, parameter identification, transfer functions, ‘ keep alive ’ requirements, or error conditions.

(b)

Details of how to obtain and interpret all fault codes which are not in accordance with the standards prescribed in Point 4.7.3 of Annex 9B to UN/ECE Regulation No 49.

(c)

A list of all available live data parameters, including scaling and access information.

(d)

A list of all available functional tests, including device activation or control and the means to implement them.

(e)

Details of how to obtain all component and status information, time stamps, pending DTC and freeze frames.

(f)

Resetting adaptive learning parameters, variant coding and replacement component setup, and customer preferences.

(g)

ECU identification and variant coding.

(h)

Details of how to reset service lights.

(i)

Location of diagnostic connector and connector details.

(j)

Engine code identification.

3.2. Test and diagnosis of OBD monitored components U.K.

The following information shall be required:

(a)

A description of tests to confirm its functionality, at the component or in the harness.

(b)

Test procedure including test parameters and component information.

(c)

Connection details including minimum and maximum input and output and driving and loading values.

(d)

Values expected under certain driving conditions including idling.

(e)

Electrical values for the component in its static and dynamic states.

(f)

Failure mode values for each of the above scenarios.

(g)

Failure mode diagnostic sequences including fault trees and guided diagnostics elimination.

3.3. Data required to perform the repair U.K.

The following information shall be required:

(a)

ECU and component initialisation (in the event of replacements being fitted).

(b)

Initialisation of new or replacement ECU’s where relevant using pass-through (re-) programming techniques.]
