Hello All!!!! I just had my truck regeared to 4.56 and now both of the brake lights come on. I took it to the dealership, and they said that it was because of the wheel sensor reporting something different than the ABS system expecting. They said it needed to be reprogrammed, but they could not do it as they only deal with stock options. (GM goes to 4.10) Is there anything out there I can buy to program the EBCM or a place that should have one? I have already programed the engine's computer through a Hypertech HyperPAC, but apparently, the EBCM needs tweeking as well. Any help would be great. Oh, its a 05 Silverado 1500 LD. 35" Tires and 4.56 Yukon Gears in the front and the rear.
