Well you should probably start with the U codes first. That is a loss of communication on the class 2 serial data line for ABS. Could be a wiring issue in the data line or could be a bad EBCM. You need a scanner so you can see which module is not responding. Your ABS and TCS lights will stay on until that code is fixed I'm sure.
