                                                           (g)    Use a multimeter to measure the resistance
                                                                  between the pin 2, 3 of DPF temperature
                                                                  sensor connector Q01 and the ground.
                                                                  Standard resistance

                                                            Multimeter connection
                                                                                           Standard value
                                                                       pin                                           04
                                                               Q01(2)- ground                  >10 MΩ

                                                               Q01(3)- ground                  >10 MΩ









                 Is the inspection result normal?
                 YES>To step 4.
                 No > Maintain or replace the harness.


                 4 .    Replace DPF temperature sensor
                 (a)    Replace DPF temperature sensor.
                 (b)    Use a diagnostic apparatus to perform DTC verification procedures.
                 (c)    Implement the steps to read sensor data stream.
                 (d)    Check whether DTC exists.
                 Is the inspection result normal?

                 YES>Replace DPF temperature sensor
                 NO >To step 5.

                 5 .    Replace ECM

                 (a)    Replace ECM.
                 (b)    Use a diagnostic apparatus to perform DTC verification procedures.
                 (c)    Implement the steps to read sensor data stream.
                 (d)    Verify that no DTC exists and the data are normal.
