TPS system won't reprogram
2002 corvette, went to 3 tire centers and they were unable to program the the tips. Used both the magnet tool and the scanner. Tires and tips sending units were replaced a year ago at Bell Tire in Michigan. Does this mean a computer problem?

A few QUESTIONS:
Have the sensors that you have in place now EVER FUNCTIONED?????
When you attempt to program them, does the TPS Function come up on the DIC???
Are the sensors that you have installed now the original sensors?
----------------------------------------------------------------------------
The actual place that you need to place the MAGNET is the spot on the RIM directly inboard of the stem.
IF,,,,,,,,,,,,,,,,,,,,,,,, You have OEM sensors, the programming tool will NOT program the sensor.

Sensors worked fine a year, new sensors were aftermarket that the tire store used. The DIC brought up the option to reprogram the tire monitoring system and then goes to the left front tire but the magnet over the valve stem or the scanner would start the process, even tried both with no success.

It's TPMS if you mean the Tire Pressure Monitoring System and not tips or TPS. TPS is Throttle Positiion Sensor which has nothing to do with tire pressure.
You need to pull and post the codes. The codes that may help determine what has happened will be listed under B0 - RFA. If you have never pulled codes on your C5 before here is how:
https://www.youtube.com/watch?v=SviRjIsy9G4
OR
http://www.c5forum.com/ayc/dtcdic.php
Post ALL your codes including the H or C or HC that follow each 5 character code. List the codes under the sensor that they are shown under. ie 10 - PCM or 28 - TCS or 40 - BCM..... etc
Loss of communications or NO COMMS can prevent the system from properly working.
Also need to know what year your C5 is....
Was the proper technique used to try and program the TPMS?

The codes above that you listed under BCM are NOT BCM codes. THey are actually RFA (Remote Function Adapter) codes and they are telling you that none of the 4 TPMS are reporting. In order they are C2100=LF, C2105=RF, C2110=RR, and C2115=LR.
I have to wonder if the TPMS were EVER correctly programmed when you first had them installed.
Aftermarket TPMS can often be very tricky to get programmed to the C5. Some require letting air out of the tires, others require a standard programming device and still others require a proprietary programming device.
I suggest that, unless you can tell us what brand TPMS was used, your best solution is going to be to get the original seller to figure out what it takes to program the product they sold you.

I suggest you CLEAR the codes go for a drive then BEFORE you kill the car retrieve the codes again.... 1 of the 4 TPMS codes you had were c-codes which are current codes... 2 were HC codes, 1 was an H code or history code... regardless of when or how long they worked if they are not reporting in now then your probably needing them reprogrammed or replaced

Frequency is what the TPMS use to transmit to the receiver (RFA) and does not relate directly to the process needed to trip them to transmit. THe "trip" or force to transmit process for those sensors does NOT use a magnet. They use a change in air pressure. When the programming process is done the TPMS transmit an ID to the RFA that gets stored in the associated location that is being programmed ( ie LF, RF....etc) so the computer knows which wheel has what pressure to display in the DIC.
If I recall correctly you need to overfill the tire pressure (perhaps 40lbs) in each tire and then start the programming process in the C5 DIC. You need to move quickly to each tire as you have only about 45 seconds per wheel to get the TPMS in that wheel to program (honk the horn) by letting air out of the tire and then move to the next wheel. IF you fail to get any one of the 4 sensors to program within the alotted time you have to start all over again at the LF tire.
Once all 4TPMS have been successfully programmed you need to then adjust the tire pressures to the correct pressure.
Good luck with the programming proccess.

Good info on the aftermarket sensors and how to program them.

I was able to find the after market sensor information from the tire company and it is Orange Electronics and the sensor part number is SC3946 and is shown on their website also for 2001-2004 corvette. They have sensors for just about every vehicle. They are located in Ohio but neither phone number is working. I wanted to contact them to find out if they can be programmed with a. Magnet or do you need their scanner, which is what it looks like. Is anyone familiar with this outfit and a way to contact them?
By the way I cleared all the codes in DIS last night now when start the car I don't get the Service Tire pressure Monitoring System but the but the tire pressure shows LF 33 RF XXXX RR 33 LR XXX.

Once you clear the DTC's for the TPMS you will have to drive the car before they will reappear. 
There are many threads on this Forum about the Orange brand TPMS. Most people that bought them for the C5 ended up returning them (or got stuck for the price of them) because they could NOT get them to program to the C5. The few that I saw that were successful on this Forum ended up letting air out as I described. A tedious process AIR....

I bought 4 sensors for mine on Ebay years ago. Knock on wood, they've been wonderful. Not totally accurate, some are off about 7% which is 2psi, but knowing that and setting with a gauge, I know I'm safe. It would be nice if they were dead on accurate but for $150, what could I expect. (that's for 4, shipped). I put new batteries in my old ones and sold them on ebay. Netted about $120 over the battery and RTV cost so I was happy. Wasn't worth the time though. That's a fair amount of work doing them.
Mine program with a magnet just like stock, fyi. I'd never heard of any programming with air pressure change. Learned something new.

Tried programming by letting air from tire with magnets, did not work. However I no longer get the service tire pressure monitoring system or any other fault codes. I have been driving it for 2 days with many restarts and no warnings.
The DIC still shows LF 35 psi (all the time) RF XXXX, RR 33 (All the time), LR XXXX. The 35 and 33 have been the same through numerous reprogramming attempts but all tires have 30 psi.
I guess I will leave system alone as long as I don't get warning codes. Go figure.

I had the very same ones with the same outcome--worked for about a year then after changing the car battery no one could program them again(tire stores, dealer, me). Got tired of the flat tire warnings and replaced them with OEM Delcos--Tire shop just broke the beads far enough down to change them out-cost 40.00. I programed them w/a microwave magnet and they've been working fine since. Stay away from aftermarket TPS--it's not worth what u save.
