It depends on the brake controller. If you have the Hopkins InSIGHT # HM47297 the manual override portion will be lit up with or without a trailer connected. But the numbers display that shows how much power is going back to the trailer brakes should only light up when a trailer is connected. I bench tested one to confirm.
If the display is showing power output with no trailer connected that is an indication of a short. The likely cause is a dirty or corroded trailer connector. Clean out the trailer connector inside and out.
I have also included some links on testing and troubleshooting brake controllers should you need them.
