If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed, road

If the same problem reoccurs, it is possible that there is an intermittent failure of the component or the ECM. Check for looseness at all harness
junctions and test for an intermittent failure.
