Can anyone tell me about these error codes I am getting on my 2007 CTS 3.6L? The codes are U1040, U1064, U1153, U1192, and P1629. I am afraid that it might be my ECM. I have 92K miles on it. Also, is the repair covered by the powertrain warranty?

Re: DTC Codes
U1064 = ECM to body control module communication - no signal
P1629 = Theft Deterrent Fuel Enable Signal Not Received Conditions
Can't find any of the other ones but I'm assuming you're correct with the bad ECM
Call the GM call center and give them your VIN and ask them what warranties are still active, and if the ECM is still covered.

Re: DTC Codes
We can check to see if any warranties are in effect as well. Send us the last 8 digits of your VIN either via email (firstname.lastname@example.org) or private message here on the forum.
