           5.     Check the signal circuit of the electronic accelerator pedal

           (a).   Ignition switch: LOCK。
           (b).   Disconnect the battery negative cable.
           (c).   Disconnect the electronic accelerator pedal connectorC98andECUconnectorC99
                  separately.


                                                      (d).    Measure  the  resistance  between  the
                                                              electronic accelerator pedal connector C98
                                                              pin2, 5 and ECU connector C99 pin 83, 61.
                                                              Maintain or change the signal harness of
                                                              the electronic accelerator pedal.
                                                              Standard resistance:


                                                               Connect the pin by       Standard value
                                                                   pmultimeter

                                                                  C98(2)-C99(83)           Approx 0Ω

                                                                  C98(5)-C99(61)           Approx 0Ω
           Is the inspection result normal?
           YES>To step 6。
           No >Maintain or change the signal harness of the electronic accelerator pedal.

           6.     Check and change the electronic accelerator pedal


           (a).   Check and change the electronic accelerator pedal.
           (b).   Using the diagnostic tool performs theDTCconfirmation procedure.
           (c).   Perform the step of reading the sensor data stream. Indentify whether the check
                  result is normal or not.


           Is the inspection result normal?
           YES>Replace the electronic accelerator pedal.
           No >To step 7。


           7.     Replace ECU


           (a).   Replace the engine ECU.
           (b).   Using the diagnostic tool performs theDTCconfirmation procedure.
           (c).   Perform the step of reading the sensor data stream.
           (d).   Verify no DTC and the normal of data.
