It means the TCM is not getting enough 12V.
But go ahead and throw money at it. Like I said earlier I just replaced my second warranty battery in less than a year.

Yes the codes are there mostly because there is not enough voltage to power up the computers, BCM , TCM or ECM. And sometimes it is attributed to a loose ground wire either back in the spare tire well, or up front in the engine bay
There is no one set reason for codes just information the computer can't evaluate and so the codes.
If your battery is over five years old! It's headed south to a retirement village in Florida!
My '07 battery died a slow low voltage , cell dead, death at just 4 years old in 2011!
Go figure.

12v is low voltage for a running HHR, should be more like 14 + voltage during a load test!
Well let's see what that electric guru finds, when he installs the new TCM.
I really hope it is a plug and place situation, and not loose wires in the TCM harness

seems that when the TCM got hot is acted up took it out let it cool down and it worked and they were able to see it and talk it when it was cool. He was able to talk to all the other modules fine. they replaced and reprogramed it and everything is working fine now. Did I mention that this has over 351k miles on it.
