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 any other emission-related power-train component connected to a computer that results in emissions exceeding any of the limits given in paragraph 3.3.2. of this annex (if active on the selected fuel type).
              6.4.2. Vehicles fitted with compression-ignition engines:
              6.4.2.1. 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 6.4.2.2. to 6.4.2.5. The technical service may substitute those conditions by others in accordance with paragraph 6.4.2.5. However, the total number of failures simulated shall not exceed four for the purposes of type approval.
              6.4.2.2. Where fitted, replacement of a catalyst with a deteriorated or defective catalyst or electronic simulation of a deteriorated or defective catalyst that results in emissions exceeding limits given in paragraph 3.3.2. of Annex 11.
              6.4.2.3. Where fitted, total removal of the particulate trap or replacement of the particulate trap with a defective particulate trap meeting the conditions of paragraph 6.3.2.2. above that results in emissions exceeding the limits given in paragraph 3.3.2. of Annex 11.
              6.4.2.4. With reference to paragraph 6.3.2.5., disconnection of any fuelling system electronic fuel quantity and timing actuator that results in emissions exceeding any of the limits given in paragraph 3.3.2. of Annex 11.
              6.4.2.5. With reference to paragraph 6.3.2.5., disconnection of any other emission-related power-train component connected to a computer that results in emissions exceeding any of the limits given in paragraph 3.3.2. of Annex 11.
              6.5. Diagnostic signals
              6.5.1.1. Upon determination of the first malfunction of any component or system, "freeze-frame" engine conditions present at the time shall be stored in computer memory. Should a subsequent fuel system or misfire malfunction occur, any previously stored freeze-frame conditions shall be replaced by the fuel system or misfire conditions (whichever occurs first). Stored engine conditions shall include, but are not limited to calculated load value, engine speed, fuel trim value(s) (if available), fuel pressure (if available), vehicle speed (if available), coolant temperature, intake manifold pressure (if available), closed- or open-loop operation (if available) and the fault code which caused the data to be stored. The manufacturer shall choose the most appropriate set of conditions facilitating effective
