Thanks as always. Just confirms the absolute necessity to have good up to date service information when working on any modern electronically controlled device of any kind.
Hey Joe, I have ISX15 and we need to run a recalibration. Do we need master password to run ECM recalibration? CUMMINS says no, but techs saying yes? Your thoughts?
Check for air getting in the fuel from the suction side. The filter on the frame (primary) is a good starting place. I am not sure what engine you have it does make a difference in what I reply with.
