Hey all I went trail riding Saturday and after riding I stopped at the main entrance to air my tires back up. The jeep would not crank had to get it towed home. I've put a scanner on it and have codes U0100, U1118, U110B, U114F. I've done a reset by disconnecting the battery and it still won't crack. The only lights that stay on on the dash are my battery light, check engine, traction control and my security light blinks. Need some help please!
Lost communication with ECM (codes U0100, U1118, U110B, U114F)

How old is the battery? Are the cable clamps clean and tight? Have the battery tested to make sure it's good. These are the first things to check.
Uh oh, your ECM may be bad. However, the first thing I would do is very, very thoroughly inspect the wiring for any breaks. This is going to take some time and patience, as there is a ton of wiring. But given that you were wheeling, it stands to reason you may have damaged something.
Usually when a lot of codes like this show up at once, it has to do with a break in the wiring, or sometimes it really is the ECM itself that's bad.

Oh wow, thanks for the update.
Sometimes stuff like this can be hard to diagnose, but I'm glad you got it figured out.
