    TPMS programming to ECU?

    "...activate the sensor. It is important therefore to have access to a Bartec Wheelrite TECH400 tool which is able to diagnose Subaru TPMS issues and also has an extra interface to the vehicle OBDII/CANbus to communicate with the vehicle Engine Control Unit (ECU) and download the TPMS data. The..."

    Above comes from a website I got to when earching for TPMS programming. Looks like the TPM-sensor ID's are stored in ECU. Anyone know anything about this?

    Yeah, they're stored in the ECU, accessible thru the OBD-2 port.

    Unless you have the correct interface tool you need to have this done at the dealer. This is why my summer set doesn't have them.

    Yep.. on all summer. To be honest I dont really notice it after the first few days. Here in the mid Atlantic we have a huge temperature fluctuation through the winter where summer stays pretty even. Plays hell with keeping tire pressure within spec. I'd rather have my winter wheels tpms active vs my summers. I also dont want to be stuck changing a tire in cold/icy weather.

    That said, the tpms are $75 each.. and though my dealer has told me they'll do the programing swap for free when I bring it in.. I'm not sure about other dealers and if they'll also charge.

    I hear you. Here in CO currently temp go from 30 to 70 during one day. Summer itself is fine, maybe winter would be too, but right now it's nuts. My TPMS is most of the time on. I'm thinking about taking out the instruments and putting a black sticker over that light. That seems to be the only solution as of now. And really, I have done without TPMS for all of my time behind the wheel...
