UP SD40T-2 Won't run in command control

I have a Lionel UP SD40T-2 locomotive 6-28540 that will only run using a transformer. When I put the locomotive on the track to try to run it in command control all the lights come on, but I can't do anything else. I've removed the shell and reseated the boards, and I've checked for wires that are broken or pinched but it still will not run-in command control. I've tried replacing the R2LC board with no luck because I can't get the locomotive to even accept a change in the ID# or a factory reset that is shown in the owner's manual. I would appreciate anyone's help with this problem. Thanks Gary
