Speaking from experience, OBD will not necessarily help you here. Something has to put the TPMS data out on the CAN bus. The rudimentary system in my old Corolla does not do this, so the only way to debug a malfunctioning TPMS system is via sdr (or an expensive tool, or a trip to the tire store).

Not just "the" CAN bus, but the one you're sniffing. Many cars have multiple busses that carry different traffic.
