They pretty much told me it was an error with my spare key and they reset the ecm and it worked fine. Then a month later it happened again where service stabilitrak keeps flashing and going away. I hooked it up to my code reader and im getting error codes that the ecm and pcm are no communicating. Has anyone had this problem. I cant figure it out i Have checked by battery and my wire harnesses and my spark plugs because they said that might be the problem. Everything is fine i can not figure out why the ecm and pcm keep getting out of communication.

Are you running your original battery? I have heard rumors batteries gong bad can cause issues.
