                                                               E05(2)- ground                 > 10 MΩ

                                                               E05(3)- ground                 > 10 MΩ




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


                 4 .    Replace the turbocharger actuator
                 (a)    Replace the turbocharger actuator.
                 (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 the turbocharger actuator.
                 NO >To step 5.

                 5 .    Check postprocessing system

                 (a)    Check if the post-processing system has extended damage.
                 Is the inspection result normal?

                 YES>To step 6.
                 No >Maintenance related faults.

                 6 .    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.
