INTRODUCTION

              This Annex describes the provisions specific to the on-board diagnostic (OBD) system for the emission control systems of motor vehicles.

         2.        DEFINITIONS

              For the purposes of this Annex, the following definitions, in addition to the definitions contained in section 2 of Annex I to Directive 2005/55/EC, apply:

              'arm-up cycle' means sufficient engine operation such that the coolant temperature has risen by at least 22 K from engine starting and reaches a minimum temperature of 343 K (70 °C);

              'access' means the availability of all emission-related OBD data including all fault codes required for the inspection, diagnosis, servicing or repair of emissions related parts of the vehicle, via the serial interface of the standard diagnostic connector;

              'deficiency' means, in respect of engine OBD systems, that up to two separate components or systems that are monitored contain temporary or permanent operating characteristics that impair the otherwise efficient OBD monitoring of those components or systems or do not meet all the other detailed requirements for OBD. Engines or vehicles in respect of their engine may be type-approved, registered and sold with such defi- ciencies according to the requirements of section 4.3 of this Annex;

              'deteriorated component/system' means an engine or exhaust aftertreatment component/system that has been intentionally deteriorated in a con- trolled manner by the manufacturer for the purpose of conducting a type-approval test on the OBD system;

              'OBD test cycle' means a driving cycle which is a version of the ESC test cycle having the same running-order of the 13 individual modes as described in section 2.7.1 of Appendix 1 to Annex III to Directive 2005/55/EC but where the length of each mode is reduced to 60 seconds;

              'operating sequence' means the sequence used for determining the conditions for extinguishing the MI. It consists of an engine start-up, an oper- ating period, an engine shut-off, and the time until the next start-up, where the OBD monitoring is running and a malfunction would be detected if present;

              'preconditioning cycle' means the running of at least three consecutive OBD test cycles or emission test cycles for the purpose of achieving sta- bility of the engine operation, the emission control system and OBD monitoring readiness;

              'repair information' means all information required for diagnosis, servicing, inspection, periodic monitoring or repair of the engine and which the manufacturers provide for their authorised dealers/repair shops. Where necessary, such information shall include service handbooks, technical manuals, diagnosis information (e.g. minimum and maximum theoretical values for measurements), wiring diagrams, the software calibration identification number applicable to an engine type, information enabling the update of the software of the electronic systems in accordance with the specifications of the vehicle manufacturer, instructions for individual and special cases, information provided concerning tools
