  • Clearing Check Eng. Light 96 Lumina 3100 OBD II

    I read somewhere on a forum how to reset the Check engine light on a 96 Lumina 3100 OBD II and can't find it through the search. Does anyone have the link or can explain how to clear the light. I had a Check engine light and then a flashing light and the car had no power and I replaced the coils the flashing stopped and runs smoother but I still have a solid light.
    Thanks,
    Mike

    Found it, To clear codes, ensure that the ignition is "OFF". Depending on the car, you can disconnect an inline "pigtail" fuse at the positive battery terminal, or remove the ECM fuse in the fuse block. Power to the ECM must be disconnected for at least thirty (30) seconds. This will cause the ECM to reset clearing all Codes, and the ECM will now need to re-learn driving parameters.

      that method only clears the light if the issue does not return.

      the code is still stored in the pcm until you have it cleared
