You're lucky then Dave.
Automotive Trade Magazines tell me that on some systems...
it's necessary to 'tell' the TPMS where which tire and it's transmitter
are now..
you have to 'teach' the system where each tire is..
on systems that have a dedicated per tire transmitter.

other systems, according to what I read use the ABS system to tell when
something is not right tire pressure wise..
and may not be able to identify 'the' tire ..
but will turn on a warning light.
The Federal requirement is that ..I think...if a tire gets below
something like 65 % of correct pressure ..
the driver gets a warning.

Personally I believe in being smarter about what is going on with one's
vehicle, not dumber.
I notice GPS can help one not keep the picture picture in their mind of
where they are going ..
kinda makes people dumber that way...for example.
