                                                                                      Standard value
                                                                 pin

                                                          E10(1)- ground                 > 10 MΩ











           Is the inspection result normal?
           YES>To step 3.

           No > Maintain or replace the harness.

           3 .    Replace oil pressure switch
           (a)    Replace oil pressure switch.
           (b)    Use the diagnostic instrument to read the oil pressure data stream.

           Is the inspection result normal?
           YES >Replace oil pressure switch.
           NO >To step 4.


           4 .    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.
