Stand by for a moment while I prepare your answer.

Once you find and fix that "U" code, everything should be okay then. the "U" code is related to the BUS/communications line and this is what has to be addressed first.

You can unplug each module one at a time to find the problem one, OR you can attach a scan tool in bidirectional mode so you can ping each module and make commands of it to see how it responds which is the best way to do it.

thanks, Ron
