Interesting read. Thanks for the detailed information, Scotty!
Ironically, my car has been throwing ID 409: TPMS Hardware Error on every drive now. Hooray...
I don't have a problem manually keeping up with my tire pressure, but this error is definitely annoying at best (the exclamation point taking place of the ability to move left on the VDS is the LARGEST annoyance of all).
Hope to see more progress toward a solution to this widely-known issue. And hey...you don't live too far from me. Perhaps I'll contract you instead of my SC to fix the issue once you've mastered it.
I'll be glad to help, I'm out in Cedar Hill.
The big issue will be fixing the receiver. It's supposed to be in the 485Mhz range (or something like that). And I don't have aything that transmits to use for a test signal source.
