'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.

                 1. A description of the type and number of the pre-conditioning cycles used for the original type approval of the vehicle.

                2.        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.

                3.        A comprehensive document describing all sensed components with the strategy for fault detection and MI activation (fixed number of driv- ing cycles or statistical method), including a list of relevant secondary sensed parameters for each component monitored by the OBD sys- tem. 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.'

ANNEX II

PROCEDURES FOR CONDUCTING THE TEST FOR DURABILITY OF EMISSION CONTROL SYSTEMS

           1. INTRODUCTION

              This Annex details the procedures for selecting a family of engines to be tested over a service accumulation schedule for the purpose of deter- mining deterioration factors. Such deterioration factors will be applied to the measured emissions from engines undergoing a periodical audit to ensure that in-service engine emissions remain in conformity with the applicable emission limits, as given in the tables in section 6.2.1 of Annex I to Directive 2005/55/EC, over the durability period applicable to the vehicle in which the engine is installed.

              This Annex also details the emission and non-emission-related maintenance
