"U" codes are only communication errors between modules
Try to delate all keys and programm it with ids

Check all wiring in and around engine fuse box for corrosion etc .
Check body module for water ingress under glovebox .
Update PCM with later calibration , specific file enhancements were made for PATS weakness on certain vehicles
