Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
The BCM will interpret no signal(s) from the TPMS as a malfunction, triggering the SERV TPM message.
BTW, bold type doesn't make your ramblings right, just annoying. What would actually be productive is to provide some real backup for your claim. You're a wealth of accurate knowledge on these trucks, Hummerz, but you're wrong on this one. Sorry, but we can't all be right all the time.
The BCM reports DTC's based on signals received! No antenna=No signal sent to the BCM=NO DTC
And around 34°F outside. Set/check tire pressures cold! The inflation pressure in tires generally drops by 1 to 2 psi for every 10 degrees the temperature lowers. Simply add a few psi for winter. I recommend 35psi, however I set my LT285's at 38psi.

Fuel fill pocket is slightly different in diameter, yet the fuel door & trim covers it.
Not blowing smoke on this 1, personal experience on my 3 happened after I washed the BCM board and connector contacts. I don't lock my 3 unless I'm out with tools inside, I stopped at the HD and grabbed my fob from the center console, shut the door, and the fob didn't respond. No problem, lock with the key in the driver's door. After a couple weeks, I went back to the BCM and found my antenna disconnected, reconnected and fob works again. The whole time driving I NEVER received>> LOW TIRE nor SERV TPMS!

Or maybe the TPMS doesn't even use the same antenna wire, but rather an internal antenna on the BCM? It's quite possible that the TPMS was in fact still working when your antenna was unplugged, but because your tires weren't low and the sensor batteries were OK, it gave no DIC messages.
As I posted above, adjust psi to ambient temp!
