I'd call that "the old fashioned way" :duh:02EnvoySLE Guy said:Pull the negative cable for the battery and leave it sitting overnight. That SHOULD reset everything I think. :m2:
You are reponding to a post that's 7 years old. :coffeeNo its simple, don't pay the money at a dealer. Disconnect negative battery, turn headlights on for five minutes to drain all power. Turn off lights and leave disconnected for a bit, 20-30 minutes. Then replug the termincal to the battery and drive for 30 minutes so computer can relearn. No need to worry about bolt on aftermarket mods, computer will learn those with time. This will just reset the computer to stock settings.
Nice info:thxWith our envoys trailblazers etc.. after you hook up the battery and before you start it you have to put the key to the on position and let the actuators recalibrate for hvac, you'll hear things moving behind the dash and in the rear, maybe takes 2 mins then fire it up
