Looking for some help diagnosing a P0573 (TCM) Cruise Control Brake Switch Circuit High Voltage DTC. Cruise control simply will not enable. I've already replaced the brake position sensor, getting the same DTC coming back after clearing & doing a BPP relearn. I've got some screenshots of my Tech2; can someone verify the voltages look ok? Any other suggestions would be appreciated. I've even tried clearing the DTC while the vehicle is driving down the road, comes right back after I try and activate cruise.
