I ran into this problem and wondered if anyone else has hit it too:

Had 4 new tires put on my 2005 Outback wagon, LLBean model so it has
the tire pressure monitors on each wheel. Tire dealer was very specific
about having appropriate equipment and training to deal with the TPMs
so it seemed like it would be easy. Picked up the car and drove for 1/2
hour - TPM light came on. Took it back to tire dealer - no light, no
problem. Finally took it back with the light on and they called me in
to the owner's office to explain the problem.

Seems that their equipment for TPM (Schraeder) was sold as being able
to deal with any cars with TPM. However, they've just found out that
Subaru (and Nisson, maybe Toyota) use proprietary equipment, not
available outside the dealership. So I now have to go to the Subaru
dealer to get the TPM system set correctly - at a cost of $18.  Subaru
delaer confirmed it and provided the price.

So - despite buying tires at a place that provides free rotations for
life, I have to take the car to the dealer following each rotation to
get the TPMs reset. An interesting situation, since it's technically
illegal for the tire dealer to release the car with the system
malfunctioning. The only way to avoid this is to have all tire work
done at a Subaru dealer!

Starting in 2007, all cars must have TPMs and at least in NY, a
functioning TPM system becomes part of the inspection. It seems like
something is wrong here, but the only person to suffer is the consumer.

Are there any other options to get around this?
