ANNEX II
1.
In accordance with the provisions of section 5 of Annex IV to Directive 2005/78/EC, the following additional information must 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, unless such information is covered by intellectual property rights or constitutes specific know-how of the manufacturer or the OEM supplier(s).
Where appropriate, the information given in this section shall be repeated in Appendix 2 to the EC type-approval certificate (Annex VI to this Directive):
1.1.
A description of the type and number of the pre-conditioning cycles used for the original type approval of the vehicle.
1.2.
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.
1.3.
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.
1.3.1.
The information required by this section may, for example, be defined by completing a table as follows, which shall be attached to this Annex:
Component | Fault code | Monitoring strategy | Fault detection criteria | MI activation criteria | Secondary parameters | Preconditioning | Demonstration test |
|---|---|---|---|---|---|---|---|
SCR catalyst | Pxxxx | NOx sensor 1 and 2 signals | Difference between sensor 1 and sensor 2 signals | 3rd cycle | Engine speed, engine load, catalyst temperature, reagent activity | Three OBD test cycles (3 short ESC cycles) | OBD test cycle (short ESC cycle) |
1.3.2.
The information required by this Appendix may be limited to the complete list of the fault codes recorded by the OBD system where section 5.1.2.1 of Annex IV to Directive 2005/78/EC is not applicable as in the case of replacement or service components. This information may, for example, be defined by completing the two first columns of the table of section 1.3.1 above.
The complete information package should be made available to the type-approval authority as part of the additional material requested in section 6.1.7.1 of Annex I to this Directive, ‘documentation requirements’.
1.3.3.
The information required by this section shall be repeated in Appendix 2 to the EC type-approval certificate (Annex VI to this Directive).
Where section 5.1.2.1 of Annex IV to Directive 2005/78/EC is not applicable in the case of replacement or service components, the information provided in Appendix 2 to the EC type-approval certificate (Annex VI to this Directive) can be limited to the one mentioned in section 1.3.2.
