ECU torque signal with the requirements of paragraphs 9.4.2.2. and 9.4.2.3. shall be demonstrated by performing the WHSC test according to Annex 4.

              8.5.4. In the case where the test equipment does not match the requirements specified in Regulation No. 85 concerning auxiliaries, the measured torque shall be corrected in accordance to the correction method set out in Annex 4.

              8.5.5. The conformity of the ECU torque signal shall be considered sufficient if the calculated torque remains within the tolerances specified in paragraph 9.4.2.5.

              8.5.6. The availability and conformity checks of the ECU information required for in-service testing shall be performed by the manufacturer on a regular basis on each produced engine-type within each produced engine-family.

              8.5.7. The results of the manufacturer's survey shall be made available to the Type Approval Authority at its request.

8.5.8. At the request of the Type Approval Authority, the manufacturer shall demonstrate the availability or the conformity of the ECU information in serial production by performing the appropriate testing referred to in paragraphs 8.5.1. to 8.5.4. on a sample of engines selected from the same engine type. The sampling rules including sampling size and statistical pass-fail criteria shall be those specified in paragraphs 8.1. to 8.3. for checking the conformity of emissions.
  9.  Conformity of in-service vehicles/engines
              9.1. Introduction

 This paragraph sets out the in-service conformity requirements for vehicles type-approved to this Regulation.
9.2. In-service conformity
9.2.1. Measures to ensure in-service conformity of vehicles or engine systems type- approved under this Regulation shall be taken in accordance with Appendix 2 to the 1958 Agreement (E/ECE/324//E/ECE/TRANS/505/Rev.2) and complying with the requirements of Annex 8 of this Regulation in the case of vehicles or engine systems type-approved under this Regulation.
9.2.2. The technical measures taken by the manufacturer shall be such as to ensure that the tailpipe emissions are effectively limited, throughout the normal life of the vehicles under normal conditions of use. The conformity with the provisions of this Regulation shall be checked over the normal useful life of an engine system installed in a vehicle under normal conditions of use as specified in Annex 8 of this Regulation.
9.2.3. The manufacturer shall report the results of the in-service testing to the Type Approval Authority which granted the original type approval in accordance with the initial plan submitted at type approval. Any deviation from the initial plan shall be justified to the satisfaction of the Type Approval Authority.
9.2.4. If the Type Approval Authority which granted the original type approval is not satisfied with the manufacturer's reporting in accordance with paragraph 10. of Annex 8, or has reported evidence of unsatisfactory in-service conformity, the authority may order the manufacturer to run a test for confirmatory
