ABS, ESP BAS, Brake light on.
Alright, so I just replaced a broken rear wheel stud on my jeep and after I started it up I'm getting ABS, ESP BAS, and Brake lights coming on. Pulled the codes and they are
U0121
U1120
U1110
Wheel speed and wheel distance error codes. From what I've read it's the ABS sensor in the rear? Just want to check before I spend the money. Maybe I busted the sensor pounding the stud out? I pulled the sensor, but really didn't know what to look for. Your input is appreciated.
Thanks

I replaced the ABS sensor and cleared the codes but it's telling me I have 2 permanent codes, u1110 and u1120. I'm at a loss right now. Anyone have any ideas?

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!

Instrument cluster lit up, speedo not working.
I'm just confused as to what caused it. I replaced a wheel stud in the rear and though maybe I messed up the ABS sensor. Replaced it and cleared codes. Everything came back.
At the same time I removed my electronic swaybar wiring plug, I clipped the wires and though it wouldn't cause an issue. (Maybe it did)
My front axle is currently not centered, but I'm not sure if or why it could be causing an issue now. Track bar should be here today to fix that though.
I just hope I can get it all fixed before I have to make my 900 mile drive home to California next Thursday. Fingers crossed.
