05 PSD F250 Trailer Brake Controller
I am getting an intermittent TBC alarm and "trailer disconnected" alarm when I'm not even towing. I have noticed that I can create the alarm by putting a cup in the dashboard cup holder or thumping the dashboard with my fist. I have checked the plugs on the back of the controller and they appear to be seated and locked correctly.
Does this symptom indicate the controller has a bad internal component that can be fixed by replacing the controller or is there another fault I should look at. Figured I'd ask before buying a $3-4 hundred dollar gizmo.

I've had this same "TBC Fault" for a while and it doesn't allow my signals nor brake lights to function. I've checked fuses and the trailer plug and I have yet to find any clear reason, other than get a new one. Has anyone found a way to bypass the TBC to allow functionality of signal lights and brakes lights?
