RDC was a unit with antennas and transmitters inside the wheel assemblies, and the TPMS is a ABS based system. it still has a TPMS unit but does not have the antennae and the other hardware.

the TPMS module should be located behind the glove compartment - wonder, if you manage to unplug and replug it, would it help reset the module and help your software connect to it?...
