Can't Sync my '98 TPMS
Just tried syncing my wheels - step by step, and no luck. At some point the original owner put on CCW wheels in place of stock. Maybe thats why horn doesn't beep when trying to synch up.

Could use more information to try to help.
When is the last time the TPMS worked?
What does your DIC display? Is it blank at each wheel? Is it “xx” at each wheel?
Does your remote door lock/unlock work?
What brand and part number sensors do you have? How old are they?
How far along did you get in the TPMS triggering process?
what are you using to trigger each TPMS?

If you're seeing pressures reported while driving they've been learned at some point.
I assume you're using a magnet - it's possible the sensors are newer and require a RF tool to trigger them. Look on amazon for OEC-T5.
Another possible way to trigger them is pressure change - I have a set for my C4 that are like this. I let air out until they were around 22lbs and then air them back up to 30 during the relearn. May not work on all sensors but is worth a try.

Did you get the single horn beep at each wheel? When you start at the LF, the car should beep the horn once the system has re-learned that location, then move to the next. I have used the magnets before but the RF xmitter handhelds work best IMO.

I agree. This is why I made the comment: If you're seeing pressures reported while driving they've been learned at some point. This would indicate the RFA is working. Hopefully he'll clarify.
rocketrod777: the RFA module is responsible for receiving both the key fob transmissions and the tire sensor transmissions. If you're able to get it into relearn mode it's possible it's semi functional and is talking to the ALDL, but it's also possible the RF receiver section in it is damaged. Have you tried learning a replacement fob also?
