Ok so i tried 3 different methods of resetting the ECM to clear codes:
1) Pull ECM cables off of unit
2) Pull fuses 42 & 43
3) Pull negative cable connection to the fuse box
Methods 2 & 3 I tried with no l luck. I waited an hour before replacing the fuses and 15 min before replacing the ground wire but neither method reset the ECM. I know this since the car started on the first try of the ignition and the check light remained on. The only method that worked was disconnecting the ECM itself. Any ideas?
