2004-2007 Cadillac CTS-V General Discussion Discussion, TPS RESET, Saw Faq, Still Have One Question in Cadillac CTS-V Series Forum - 2004 - 2007; So I reprogged my TPS sensors as they werent displaying the tire pressures. It indicated to end on the rear ...
I would just re-do it the correct way. Since they use an RF signal, or whatever, I'd imagine there's a reason for doing it in a specific order. The computer probably sets them in a specific order. After you set each tire, I think you can go look and see which one is registered and which isn't. At least, it appears to be like that, in the instructions. They can't be on the wrong rim, I don't think they have to be on a certain one, just have to be registered in an order.
The computer learns them in a specific order. That order is LF, RF, RR, LR. Each sensor sends an individual RF signal and is learned by the computer in that order. This is so you can replace the sensors or reprogram the computer when you rotate tires.
Almostav - You can simpy let out some air from each tire, one at a time, and see which one has changed on your display.
The order in the FAQ is correct. Plus the entire procedure is also spelled out for you in the owner's manual. It has taken me a few tries to get the first honk to start the sequence. However, once it gets going, it will work. The key is to let the air out of each tire for a bit (3-5 secs) then wait for the sensor to read the new data. If you don't get an acknowledgement honk right away, let a little bit more air out. And then wait for the honk. Shouldn't take more than 30 seconds per tire.
