something like: "Tire monitoring not active"

It won't reset and the tire icon is lit all the time, occaionslly it will change to "not active" then go back to just the icon.

It always gives the "Inactive" message upon starting.

Resetting it doesn't work.

any ideas?

When water got into my trunk it fried the RDC module responsible for tpms. Maybe this somehow happened to you? It is located behind the passenger wheel arch in the trunk, in front of the tail light. It is below the little "tray" in the carpet. If it is, you can just code it out and use the euro ABS style TPMS.
