I will pull the fuses during lunch and report back. Thank you!
I wanted to cross this off the list as a possible cause so I made sure to check and clean the pistons last Sunday while I did the rotor/pad change and bleed. The pistons looked pretty good from the start plus I could easily push them in by hand when installing the track pads.
It looks the ABS (module) is the problem. I pulled the fuses and the brakes worked perfectly. Good call! Now I just need to get the module rebuilt.
