Because I like to , I did some investigating and found this CTM/BCM reset directions..

Sounds like it couldn't hurt to try it, and won't hurt a thing as both terminals would be disconnected from any power. I also saw some posts that said it may need to be flashed by the dealer , and should also be one from the same year and options if you use a used one.

( RESET INSTRUCTIONS ) Normally the CTM can be reset and fixed by disconnecting the battery and touching the terminals together. Doing this would have saved you 200 bucks

 

Definitely worth a try, thanks.
