Brake controllers such as your new P3, # 90195, will stay active until about 15 minutes of sensing no activity and then they will go into a power saving mode.

If the controller does not go into power saving mode then there is likely some power draw making it think there is still activity. The most likely cause of this is a dirty or corroded trailer connector on the truck, trailer, or both.

Make sure the connectors are clean and free of corrosion inside where the wires attach as well as on the pins.
