         6.3.  Failure modes to be tested

         6.3.1. Positive-ignition engined vehicles:

         6.3.1.1. replacement of the catalyst with a deteriorated or defective catalyst or electronic simulation of such a failure;

         6.3.1.2. engine misfire conditions according to the conditions for misfire monitoring given in paragraph 3.3.3.2. of Annex 11;

         6.3.1.3. replacement of the oxygen sensor with a deteriorated or defective oxygen sensor or electronic simulation of such a failure;

         6.3.1.4. electrical disconnection of any other emission-related component connected to a power-train management computer (if active on the selected fuel type);

         6.3.1.5. electrical disconnection of the evaporative purge control device (if equipped and if active on the selected fuel type). For this specific failure mode, the Type I test need not be performed.

         6.3.2.  Compression-ignition engined vehicles:

         6.3.2.1.  where fitted, replacement of the catalyst with a deteriorated or defective catalyst or electronic simulation of such a failure;

         6.3.2.2.  where fitted, total removal of the particulate trap or, where sensors are an integral part of the trap, a defective trap assembly;

         6.3.2.3. electrical disconnection of any fuelling system electronic fuel quantity and timing actuator;

         6.3.2.4.  electrical disconnection of any other emission-related component connected to a power-train management computer;

         6.3.2.5.  in meeting the requirements of paragraphs 6.3.2.3. and 6.3.2.4., and with the agreement of the approval authority, the manufacturer shall take appropriate steps to demonstrate that the OBD system will indicate a fault when disconnection occurs.

         6.4.  OBD system test

         6.4.1.  Vehicles fitted with positive-ignition engines:

         6.4.1.1.  after vehicle preconditioning according to paragraph 6.2., the test vehicle is driven over a Type I test (Parts One and Two);

         the MI shall activate before the end of this test under any of the conditions given in paragraphs 6.4.1.2. to 6.4.1.5. The technical service may substitute those conditions by others in accordance with paragraph 6.4.1.6. However, the total number of failures simulated shall not exceed four (4) for the purpose of type approval;

         6.4.1.2.  replacement of a catalyst with a deteriorated or defective catalyst or electronic simulation of a deteriorated or defective catalyst that results in emissions exceeding the HC limit given in paragraph 3.3.2. of Annex 11;

         6.4.1.3.  an induced misfire condition according to the conditions for misfire monitoring given in paragraph 3.3.3.2. of Annex 11 that results in emissions exceeding any of the limits given in paragraph 3.3.2. of Annex 11;

         6.4.1.4.  replacement of an oxygen sensor with a deteriorated or defective oxygen sensor or electronic simulation of a deteriorated or defective oxygen sensor that results in emissions exceeding any of the limits given in paragraph 3.3.2. of Annex 11;

         6.4.1.5.  electrical disconnection of the electronic evaporative purge control device (if equipped and if active on the selected fuel type);

         6.4.1.6.  electrical disconnection of
