im thinkin you have to pull the pcm, open your glove box and pull it out by pushing the sides in and it should come out and the pcm is on the right hand side. i think you can get the code w/o pulling it out.
You can find your code on a sticker.Open the passager side door and look where the door hing is. It will be right there in plain site stuck to the car, not the door. It's white with big black letters, can't miss it!
