Resetting or Relearning the Wheel Hub Sensor to ECM, PCM, or TCM

Has anybody heard of resetting / relearning the TCM, PCM, or ECM to new wheel hubs for a 05 Cadillac STS (w/4.6)? If so, what's the best course of action to do this? I currently have no HID lights indicating a problem.

so you currently have no low beams (HID) because you put new wheel hubs on i have never herd of this... you might want to find a mechanic that can do relearnign

What makes you think it's related?

If you don't have headlight washers, your HID's are after-market. If that's the case, ballasts go bad as often as bulbs.

My fault, I meant to say HUD (Heads up display). I finally foundmy drivetrain noise. The tires.

Relating to the original question, I've never heard of such a procedure. The wheel speed sensors connect to the Electronic Brake Control Module (EBCM). If there was some sort of fault, you would have a message or indicator relating to ABS, traction and/or stability control. There is a relearn process relating to wheels for TPMS matching but this isn't affected unless you start moving wheels to different positions on the car. The wheel hubs are basically plug and play.

I'm just happy that it didn't cost me too much to figure it out. The rotors, pads, and brake hardware were looking bad. The passenger hub did have a grinding sound coming from it and the tires didn't have much tread left on them. After my time and money, it was a small price to pay to keep up with the maintenance.
