I think all you have to do is disconnect the negative side of your battery and press the brake pedal to drain the extra power left in there and reconnect the battery.

Really? I read something about connecting some black wire to a black wire and green to green. Then driving around and reconnecting the wires....

just disconnect your battery, ground side, and let it sit for about 30-45 minutes. Then reconnect, start it up and your good to go.

Are you trying to clear some check engine lights? If you are, plugging out the battery will not work. Use an OBDII diagnostic software to clear it. Or try this, I tried and it worked. If you have turbo timer, off it totally. Start your car 3 times in a row, shut it down immediately after she is fired up. 4th time, start and let it idle. This worked for me around 5 times only. Beyond that, it doesn't work anymore. My local dealer taught me that.....
