From a quick search of the codes... "U1110 means the PCM didn't receive a vehicle speed signal from the Anti-lock brake Module over the CAN C bus. Are you sure this wasn't accompanied by U0121? If not, you need a new PCM. If you have the U0121, then you may just need an ABS module. U1120 is a lost wheel distance message. It has the same possible causes as the above. Both can also be caused by a short in the CAN C bus as well. You need a mechanic for this one, unless you have the proper scan tool to run a Powertrain Verification Test." So sounds like the dealer is the way to go on this one. Update the thread when it's fixed for future searchers if you don't mind. Good luck!

Sounds to me like the ABS module based on the codes. And I remember from reading another thread that a new ABS module needs to be programmed by the dealer anyway. So I think you're stuck there. I don't think any of the other things you've done are the problem.
But I'm just making a guess based on the fact that people replace the wheel sensors all the time with no issues. I also don't know why the SB disconnect would affect the ABS module. I have no first hand experience with it though.
The ESP and BAS lights could be a bad sensor or wire. I know you said you replaced the sensor but did you check the wires to it to make sure they weren't damaged? Also some guys have reported the same lights for a bad unit bearing. You could check that if you feel so inclined.

I did find I have a blown swaybar fuse (j11) which I'm guessing blew when I cut the wires.
I don't know at this point, but we will see what the dealer says on Saturday.

Just wondering if anyone has an ideal if my issue could be related to the swaybar wiring or if it's unrelated?

Dealer says there is no communication with the ABS system, they think it's the ABS Module. $450 parts and labor. Trying to see if my extended pre-owned warranty will cover it.
