    Hey everyone I have a 2009 internstional cummins isx. The warning engine light has came on and stayed on, the truck runs just fine with it on. Nothing seems to be a matter. Any ideas what could cause this. Truck shows no codes manually but haven't hooked to computer yet

    Unfortunately the light has came on and stayed on, I'm afraid I might get stuck couple hours away.

    That's exactly what mine doing. It will come on if I turn the truck off and back on it goes away for days sometimes weeks then it will do the same thing again

    Find someone with Cummins INSITE and have them pull your fault codes.
