Did you scan your DSC and actually see what data it is reporting? What about any fault codes?
I solved my trifecta lights by first seeing that the SAS was not reporting rational values. Once I solved the SAS, I then looked at the wheel speed sensors via DSC and found that my module was getting erratic signals from the front driver side. That's when I chose have my module rebuilt, and voila...fixed!
