           3 .    Check DPF temperature sensor circuit
           (a)    Ignition switch: OFF.
           (b)    Disconnect the battery negative cable.
           (c)    Disconnect DPF temperature sensor connector Q01.
           (d)    Connect the battery negative cable.
           (e)    Ignition switch: ON.

                                                      (f)    Use a multimeter to measure the resistance
                                                             between the pin 4 of DPF temperature sensor
                                                             connector Q01 and the ground.

                                                                                      Standard value
                                                                 pin
                                                         Q01(4)- ground               Battery voltage












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


           4 .    Check DPF temperature sensor harness
           (a)    Ignition switch: OFF.
           (b)    Disconnect the battery negative cable.
           (c)    Disconnect DPF temperature sensor connector Q01.
           (d)    Disconnect connector E01 of ECM.

                                                      (e)    Use a multimeter to measure the resistance
                                                             between the pin1 of DPF temperature sensor
                                                             connector Q01 and the ground.
                                                             Standard resistance


                                                       Multimeter connection          Standard value
                                                                 pin

                                                         Q01(1)- ground                   <10 Ω
