                                                               K001(3)- ground                > 10 MΩ









                 Is the inspection result normal?
                 YES>To step 5.
                 No > Maintain or replace the harness.


                 5 .    Replace combination instrument
                 (a)    Replace combination instrument.
                 (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 combination instrument.
                 NO >To step 6.

                 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.
