My resting 12v charge is at 12.45v after parking all night. If that is the reason for the TCU not working, then I'll just wait until it ages closer to death before buying a new battery. I have had an Optima in my Amazon basket for a few months now, but I'll just suck some more life out of the OEM one.
What helps me is I park in the garage at home, and in the basement at work. So preheating or precooling is more of a gimmick than anything else.
