Yes, that is what I thought also. But that is not what happened in my small rural community..

First of all, due to lack of familiarity by both myself, and the technician performing the TPMS work, my vehicle's sensors were not replaced properly. And I had to unravel the problem. And then fix it: This is what happened to me (I earlier left out all the details):

First of all, the Bartec tool at the Goodyear tire shop has a menu that tells the technician which replacement sensors to use for each vehicle. That Bartec menu happens to have the wrong frequency information listed for my year and model Crossfire (2005 SRT6). The technician doesn't realize this, so he replaces my sensors with the wrong frequency sensors. The Bartec tool then attempts a relearn sequence with the wrong frequency sensors. The tool then says to go to the dealer.

The dealer can't find the problem, charges $75 and says a $300 part needs to be replaced that may or may not fix the problem.

Costco tries to fix the problem, but they also have a Bartec tool. So same outcome there. But at least they quickly, realize they can't help and don't charge anything.

Firestone then tries to solve the problem using their Snap On tool. They work on it about 1/2 hour. The Snap On tool talks to the Crossfire TPMS, but can't perform a relearn, because the wrong frequency sensors are installed. Firestone apologizes for why their $10,000 TPMS tool can't solve the problem, and doesn't charge. By this time a TPMS failure code gets permanently set in the system.

So I realize at this point that there is problem and I may need to try and fix this problem myself. Because tractors outnumber Crossfires 10000 to 1 where I live.

First of all I investigate (using helpful information from this forum) and discover the wrong frequency sensors were installed on my vehicle. Then I again check Crossfire Forum, purchase the dual frequency EZ sensors reccommended on this site, and have them installed and cloned to the old sensor ID's. That meant replacing the batteries temporarily in two of the four old sensors so they could chirp out their ID codes to be cloned. The technician then used the Bartec tool to read all the old sensors and clone everything. I was hoping that would solve the problem. But unfortunately, it didn't. Because a TPMS failue code was stored in the system, as a result of the previously failed relearn attempts.

So there was now one additional problem to overcome: Resetting the TPMS system failure code in the system.

That was done by using the DRB III, and following the on screen instructions to clear the failure code. Those instructions said a relearn sequence was required and automatically started the process. After the process was completed, everything worked fine.

And now you know the rest of the story. It's a real TPMS saga!
