Commission Directive 2005/78/EC of 14 November 2005 implementing Directive 2005/55/EC of the European Parliament and of the Council on the approximation of the laws of the Member States relating to the measures to be taken against the emission of gaseous and particulate pollutants from compression-ignition engines for use in vehicles, and the emission of gaseous pollutants from positive ignition engines fuelled with natural gas or liquefied petroleum gas for use in vehicles and amending Annexes I, II, III, IV and VI thereto (Text with EEA relevance) · European Union

Annex VI is amended as follows: The Appendix becomes ‘Appendix 1’. Appendix 1 is amended as follows: The following section 1.2.2 is added: 1.2.2. Engine Control Unit (EECU) software calibration number:’ Section 1.4 is replaced by the following: ‘1.4. Emission levels of the engine/parent engine (*): 1.4.1. ESC test: Deterioration factor (DF): calculated/fixed (*) Specify the DF values and the emissions on the ESC test in the table below: 1.4.2. ELR test: smoke value: … m–1 1.4.3. ETC test: Deterioration factor (DF): calculated/fixed (*) (*) Delete what is not applicable.’ " (*) Delete what is not applicable.’ " (*) Delete what is not applicable.’ " ESC test DF: | CO | THC | NOx | PT | | | Emissions | CO (g/kWh) | THC (g/kWh) | NOx (g/kWh) | PT (g/kWh) Measured: | | | | Calculated with DF: | | | | ETC test DF: | CO | NMHC | CH4 | NOx | PT | | | | Emissions | CO (g/kWh) | NMHC (g/kWh) (7) | CH4 (g/kWh) (7) | NOx (g/kWh) | PT (g/kWh) (7) Measured with regeneration: | | | | | Measured without regeneration: | | | | | Measured/weighted: | | | | | Calculated with DF: | | | | | The following Appendix 2 is added: ‘Appendix 2 OBD RELATED INFORMATION As noted in Appendix 5 of Annex II to this Directive, the information in this appendix is 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. Such information need not be supplied by the vehicle manufacturer if it is covered by intellectual property rights or constitutes specific know-how of the manufacturer or the OEM supplier(s). Upon request, this appendix will be made available to any interested component, diagnostic tools or test equipment manufacturer, on a non-discriminatory basis. In compliance with the provisions of section 1.3.3 of Appendix 5 to Annex II, the information required by this section shall be identical to that provided in that Appendix. A description of the type and number of the pre-conditioning 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. A list of all OBD output codes and format used (with an explanation of each) associated with individual emission related powertrain components and individual non-emission related components, where monitoring of the component is used to determine MI activation.’
