Below are the diag steps for this U communication code. There are 2 wires to each module for the CAN BUS communication circuit and there is an issue with these wires or a module or its from a scan tool communication issue.
Do you know your engine code and the vehicle build date. I can then get you a fuse box diagram so you can check correct fuse locations.
Thanks for asking your question and letting me try to help you.
