CHAPTER 5U.K. CONFORMITY OF SIMULATION TOOL OPERATION, INPUT INFORMATION AND INPUT DATA

Article 20U.K. [F1Responsibilities of the vehicle manufacturer, the approval authority and the Commission with regard to the conformity of simulation tool operation]

1.The vehicle manufacturer shall take the necessary measures to ensure that the processes set up for the purposes of determining CO2 emissions and fuel consumption for all the vehicle groups covered by the licence granted pursuant to Article 7 or the extension to the licence pursuant to Article 8(1) continue to be adequate for that purpose.

[F2The vehicle manufacturer shall, on a yearly basis, perform the verification testing procedure set out in Annex Xa on a minimum number of vehicles in accordance with point 3 of that Annex. The vehicle manufacturer shall provide, until 31 December of each year and in accordance with point 8 of Annex Xa, a test report to the approval authority for each vehicle tested, shall keep the test reports for a duration of at least 10 years and shall make them available to the Commission and approval authorities of the other Member States upon request.]

2.The approval authority shall perform, four times per year, an assessment as referred to in point 2 of Annex II in order to verify if the processes set up by the manufacturer for the purposes of determining CO2 emissions and fuel consumption for all the vehicle groups covered by the licence continue to be adequate. The assessment shall also include verification of the selection of the input information and input data and repetition of the simulations performed by the manufacturer,

[F2Where a vehicle fails the verification testing procedure set out in Annex Xa, the approval authority shall start an investigation to determine the cause of that failure, in accordance with Annex Xa. As soon as the approval authority determines the cause of the failure, it shall inform the approval authorities of the other Member States thereof.

If the cause of the failure is linked to the operation of the simulation tool, Article 21 shall apply. If the cause of the failure is linked to the certified CO 2 emissions and fuel consumption related properties of components, separate technical units and systems, Article 23 shall apply.

If no irregularities could be found in the certification of components, separate technical units or systems and the operation of the simulation tool, the approval authority shall report the vehicle failure to the Commission. The Commission shall investigate whether the simulation tool or the verification testing procedure set out in Annex Xa has caused the vehicle to fail and whether an improvement of the simulation tool or the verification testing procedure is necessary.]
