signals through the serial port connector referred to in paragraph 6.5.3.2. (c). of Appendix 1 to Annex C5.

              3.1. For all vehicles referred to in paragraph 5.11. of this Regulation, with the exception of OVC-HEVs:

               (a) Total fuel consumed (lifetime) (litres);

               (b) Total distance travelled (lifetime) (kilometres);

               (c) Engine fuel rate (grams/second);

               (d) Engine fuel rate (litres/hour);

               (e) Vehicle fuel rate (grams/second);

               (f) Vehicle speed (kilometres/hour).

              3.2. For OVC-HEVs:

                  (a) Total fuel consumed (lifetime) (litres);

                  (b) Total fuel consumed in charge-depleting operation (lifetime) (litres);

                  (c) Total fuel consumed in driver-selectable charge-increasing operation (lifetime) (litres);

                  (d) Total distance travelled (lifetime) (kilometres);

                  (e) Total distance travelled in charge-depleting operation with engine off (lifetime) (kilometres);

                  (f) Total distance travelled in charge-depleting operation with engine running (lifetime) (kilometres);

                  (g) Total distance travelled in driver-selectable charge-increasing operation (lifetime) (kilometres);

               (h) Engine fuel rate (grams/second);

               (i) Engine fuel rate (litres/hour);

               (j) Vehicle fuel rate (grams/second);

               (k) Vehicle speed (kilometres/hour);

               (l) Total grid energy into the battery (lifetime) (kWh).

              4. Accuracy

              4.1. With regard to the information specified in paragraph 3., the manufacturer shall ensure that the OBFCM device provides the most accurate values that can be achieved by the measurement and calculation system of the engine control unit.

              4.2. Notwithstanding paragraph 4.1., the manufacturer shall ensure that the accuracy is higher than - 0.05 and lower than 0.05 calculated with three decimals using the following formula:

              Where:

                                Fuel_ConsumedWLTP (litres)  is the fuel consumption determined at the first test carried out in accordance with paragraph 1.2. of Annex B6, calculated in accordance with paragraph 6. of Annex B7, using emission results over the total cycle before applying corrections (output of step 2 in Table A7/1 of Annex B7), multiplied by the actual distance driven and divided by 100.

                                Fuel_ConsumedOBFCM (litres) is the fuel consumption determined for the same test using the differentials of the parameter 'Total fuel consumed (lifetime)' as provided by the OBFCM device.

              For OVC-HEVs the charge-sustaining Type 1 test shall be used.

              4.2.1. If the accuracy requirements set out in paragraph 4.2. are not met, the accuracy shall be recalculated for subsequent Type 1 tests performed in accordance with paragraph 1.2. of Annex B6, in accordance with the formulae in paragraph 4.2., using the fuel consumed determined and accumulated over all performed tests. The accuracy requirement shall be deemed to be fulfilled once the accuracy is higher than - 0.05 and lower than 0.05.

              4.2.2. If the accuracy requirements set out in paragraph 4.2.1. are not met following the subsequent tests pursuant to this point, additional tests may be performed for the purpose of determining the accuracy, however, the total number of tests shall not exceed three tests for a vehicle tested without using
