I have never seen a IDM fail on one bank. When they do fail, the truck usually will not start, or it will fail for 1 or 2 injectors, not 1 bank. I would also bet that it is the UVC harness. There are clips available for the UVC harness that will keep it from coming out again if you don't want to replace the whole harness. It's better than spending $60+ for the harness itself. That is more than likely the reason it will not communicate with one bank. It doesn't see that bank because the UVC is disconnected.
