Above, I asked if you had done the first step of diagnosing a problem on a modern vehicle. This has not been answered.
It's not the most encouraging when you offer help to someone and the response is 'i know more than you'.
But, to answer your question, there's not one.
04-06 cars have indirect TPMS, and do not have a dedicated module. It uses the EBCM and ABS modules and determines tire pressure variances by wheel speed. In these, different tire sizes, and levels of wear CAN effect TPMS operation. It also could be related to any TCS or ABS issues.
07-08 uses a combined effort of the sensors in the wheels, RCDLR (door lock receiver), DIC, and IPC to monitor the actual pressure inside the tire. Didn't you just replace the DIC? Hm.
In either system, you need to pull codes.
