CERTAIN VEHICLES EQUIPPED WITH THE DURAMAX DIESEL ENGINE MAY HAVE A MAIN ENGINE WIRING HARNESS THAT IS NOT PROPERLY FASTENED AND MAY COME INTO CONTACT WITH A SHARP GASKET TAB USED FOR CONTROLLING EMISSIONS (EGR GASKET VERIFICATION TAB). THE SHARP GASKET TAB CAN CUT INTO THE WIRING HARNESS AND EVEN SEVER WIRES IN THE HARNESS. DEPENDING ON WHICH WIRE IS AFFECTED, YOU MAY RECEIVE A “REDUCED POWER MODE” INDICATOR LIGHT IN THE INSTRUMENT PANEL, OR YOU MAY NOT BE ABLE TO START YOUR VEHICLE.
