Answers :

You have an ECM and a BCM, one located behind your glove box and the other underneath your passenger side dash. They are very similar in size, shape, and color but i think the ECM s behind the glove box. I had the same problem and replaced the one behind the glove box and the problem went away. They are both easy to replace but they cost around $70 if I remember correctly. And you have a chip you have to swap from the old to the new that you have to be careful with.
