FEDBYVORTECH Posted May 22, 2013 Report Share Posted May 22, 2013 My 04 SS, has been doing this for years now. Every time I come up for inspection I have to go through drive cycle to reset the monitors, than leave truck running and hope they can inspect it. If I reset my oil life with the truck off after a few hours it goes from 100% to 0. I took the plugs off the ECU checked pin 20 & 57 on C1 connector they have 12v with truck off. I am thinking it is the ECU. Anyone have any input? Outside of this, the truck runs and drives perfect. Thanks for any input Quote Link to comment Share on other sites More sharing options...
