                                                      (f)    Use a multimeter to measure the resistance
                                                             between the pin 1, 2 of 1 cylinder injector
                                                             connector E12 and the ground respectively.

                                                          E12(2)- ground                 > 10 MΩ









           Is the inspection result normal?
           YES>To step 3.
           No > Maintain or replace the harness.


           3 .    Replace 1 cylinder injector
           (a)    Replace 1 cylinder injector
           (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 1 cylinder injector
           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.
