              4.2.2. For Level 1A

              The Type Approval Authority will not accept any deficiency request that does not respect the OBD thresholds set out in paragraph 6.8.2. of this Regulation.

              For Level 1B

              The responsible authority shall reject any deficiency request that does not respect the OBD thresholds set out in regional legislation multiplied by a factor required by regional legislation up to a maximum factor of two.

              4.3. In determining the identified order of deficiencies, deficiencies relating to paragraphs 3.3.3.1., 3.3.3.2. and 3.3.3.3. of this annex for positive ignition engines and paragraphs 3.3.4. (a), (b) and (c) of this annex for compression-ignition engines shall be identified first.

              4.4. Prior to or at the time of type approval, no deficiency shall be granted in respect of the requirements of paragraph 6.5., except paragraph 6.5.3.5. of Appendix 1 to this annex.

              4.5. Deficiency period

              4.5.1. A deficiency may be carried-over for a period of two years after the date of type-approval unless it can be adequately demonstrated that substantial vehicle hardware modifications and additional lead-time beyond two years would be necessary to correct the deficiency. In such a case, the deficiency may be carried-over for a period not exceeding three years.

              4.5.2. A manufacturer may request that the Type Approval Authority grant a deficiency retrospectively when such a deficiency is discovered after the original type-approval. In this case, the deficiency may be carried-over for a period of two years after the date of notification to the Type Approval Authority unless it can be adequately demonstrated that substantial vehicle hardware modifications and additional lead-time beyond two years would be necessary to correct the deficiency. In such a case, the deficiency may be carried-over for a period not exceeding three years.

              4.6. At the request of the manufacturer, a vehicle with an OBD system may be accepted for type-approval with regard to emissions, even though the system contains one or more deficiencies such that the specific requirements of this annex are not fully met, provided that the specific administrative provisions set out in section paragraph 3 of this annex are complied with.

              The Type Approval Authority shall notify its decision in granting a deficiency request to all other Contracting Parties to the 1958 Agreement applying this Regulation.

Annex C5 - Appendix 1

Functional aspects of On-Board Diagnostic (OBD) systems
              1. This appendix describes the procedure of the test according to paragraph 3. of this annex. The procedure describes a method for checking the function of the On-Board Diagnostic (OBD) system installed on the vehicle by failure simulation of relevant systems in the engine management or emission control system. It also sets procedures for determining the
