mtnmedic, your trouble codes refer to communications over CAN bus C, not the wheel sensors. Wheel sensor problem codes are preceded by the letter C, not U. The FSM says your codes are a problem with the Powertrain control module, the antilock brake module, or the wiring in between. If it was the wiring, you should have a lost communications code too.
To me, it sounds like the ABS module is still confused from having a bad battery. I would try disconnecting the battery for a few minutes to see if that will reset the problem. Did you clear all trouble codes after the battery replacement? Does the ABS system still actually work? How about ESP?
