I drove home and tried to program the sensors myself with a speaker magnet without any luck. I ordered a Schrader 20143 TPMS Magnet from Amazon as a last resort and it did the trick. All four tires programmed the first time through with the Schrader magnet. I have no idea why the tire store couldn't get them to program or why the Schrader magnet worked when it did. For less than $20.00 dollars, I'd get the Schrader magnet and give it a try.

Find the BLANK program in the DIC and press reset. Select TPM Training

YOU MUST USE A MAGNET at each valve stem The sensor is on the INBOARD side of the valve stem

Your FIRST sensor program wheel will be the drivers front.

One would think that these aftermarket vendors would make sure they work according to the specs. of the vehicle they make them for. And to follow their instructions they need to be mounted in order to increase or decrease air pressure.

You hold it at the valve stem, not all over the tire. First time I did it with a 3/8" x 1/2" neodymium magnet. It finally worked, but I almost gave up. Second time I did it with a bigger magnet -- woofer magnet out of door panel speaker. Much better. Seems to like you just holding the magnet steady beside the valve stem rather than waving it.
First time was a pain, so second time I told the tire shop to do it. They tried and tried using their universal programmer and could not program it. I was ready to buy the new fob/receiver system and figured "what the heck, I will try it the old fashioned way, on the DIC". Worked like a charm.

Once the training function is started and the horn honks to indicate the first TPMS is trained, the message in the DIC will change to tell you which TPMS to train next. The horn will honk after each TPMS is trained. The actual tire pressures will not change until the car has been driven with the trained TPMS.

If your trying to tell us that you cannot get the TPMS training to display in the DIC then possibly a previous owner had the TPMS RPO programmed out of the BCM. That is possible for 2001 and newer C5's. requires a TECH II device to remove or add the RPO to the BCM. It could also be a bad BCM. Has the BCM ever gotten wet?

The OEM ones have a circle with an arrow pointing to a number between 1 and 12 to indicate the month and a two digit year (one digit on either side of the arrow). Perhaps you have old TPMS and the batteries are bad???

You might try a stronger magnet. Are the TPMS that you cannot train Titan by chance??? Many have had issues trying to get that particular brand to train in a C5. If they are Titan then I suggest that you contact the company with your issue. You would not be the first......

As far as checking the BCM, it is located in the passenger foot well to the left of the IP fuse box behind the toe kick at the end of the foot well. The board is inside a large aluminum container. Look at the aluminum container for white oxidation stains that would indicate that water had gotten in that area and possibly had contaminated the board inside the container. Container is NOT water tight.

If you have water stains on the container then I would start by reading the following thread:

Pure BS from who ever told you that...........

Good luck with the new sensors....
