TPMS Question
Hello,
Will there be an error displayed if the TPMS Units are not present at all? I've read about retraining and I tried but I can't get the horn to honk or move to the next tire. I am now wondering if the new wheels and tires actually have the TPMS units installed (I did pay for new ones to be installed).
right now the TPMS does have an error but it states the pressure is low...reading is around 24PSI (which is 10PSI lower than actual). I guess I am hoping that it would read TPMS not found or something like that if it was not there at all.
I may have to take the tires in to have them opened up and looked at.
Does anyone have a trust worthy place around Tampa Bay?
Thanks,
Kevin

There are multiple different types of aftermarket TPM's available for the C5. Some require a magnet to do the "training", others require air to be let out of the tire and still others require a special programming tool.
Without knowing the brand of TPM that was installed you will not know how to do the "training". I would definitely do as 73 suggested and take the car back to the place that you paid to install them......
You can tell if the car knows about the TPMS by pulling and posting your codes. If you have never pulled codes on your C5 here is how:

OR
http://www.c5forum.com/ayc/dtcdic.php
Write down all the codes includng the H or C or HC that follow each 5 character code. Post the codes in this thread and and list them under the sensor they show up under. ie 10 - PCM or 28 - TCS or 40 - BCM...... etc. The codes for the TPMS will show up under B0 - RFA.

Thanks for the information, I wish I could take them back to the place I bought them...unfortunately, I bought the wheels and tires from Need4Speed in California (and I live in Florida) and they have been completely unresponsive. I've had nothing but problems with that company once they got my money. Anyhow, looks like I'll be out anther few hundred dollars in this venture...
EDIT: I pulled the codes and for BO-RFA the codes are C2100, C2105,C2110, and C2115. These all are TPM issues. I have no idea if this means that they are simply not there or that they need to be trained.
Best,
Kevin

Well, you may be able to salvage the TPMS if you can find a reputable tire shop in your area that can dismount one tire to determine what brand of TPMS were installed. The should be able to determine how to go about programming them once they know what brand were installed. Might be worth a small additional investment to avoid throwing away hundreds on TPM's that may still be functional..... JMHO

Looks like that sensor may require a special tool to make it functional

I do recall that thread. THe procedure is a royal PIA because you have 45 seconds per wheel to do the programming. If you exceed the 45 seconds on any one wheel you have to start all over again at the left front wheel even if it that one was successfully programmed.......... 
I got it to work once...I could not get it to work again...will need to drive a little tomorrow to see in the sensors transmit pressure correctly.

1. I needed to manually clear the error codes using the method privided by ZIP corvettes.
2. I inflated the tires to 40PSI (looks like the upper tolerance is 42PSI...so this may or may not be good, it worked for me)
3. I went for a 30 minute drive.
4. Parked, shut of engine, removed key, reinserted key, and then entered TPM Training. (thanks 8Vette7!!)
5. Went to each tire in the correct order (LF. RF, RR, LR) and let air out of the tires until the horn honked for each one. It took anywhere from 23 to 30 seconds of air removal...I had almost given up but it finally worked. Each TPM can have a different amount of air removal required.
6. Noticed that 3 of the 4 sensors were reading correctly. So, I went for a short 10 minute drive. I parked again and was going to redo the procedure because the one sensor was still not reading correctly...as soon as I parked and opened the door, the last sensor updated and was reading correctly!
7. I suppose the old adage is true...patience is a virtue
Best of luck to those of you tinkering with your TPM's and hope this helps
Thanks to 8VETTE7 and 73Corvette for your help, very much appreciated!
Kevin

From what I could gather about those sensors is that you can use their tool to either clone the original sensors or program the sensors to work in place of the original sensors.
Clone would not require you to train the sensors assuming you put the new where the old were.
Just programming them makes them work like the proper sensor new and would require you to train them.
Unless it has changed, the ITM web site doesn't say ANYWHERE how to program them. Not on the site, the FAQ, the documents. Nowhere.
