Traction control light stays on
If you're not getting an OBD (on board diagnostic) code, and it is constantly flashing, then the system needs to be calibrated at the dealer. This occurs when you replace or disconnect/reconnect a component of the traction control system, i.e., the sensors (shared with the ABS system), to the steering wheel position sensor, or the yaw sensors, etc. If you have it calibrated and it comes back on, you've got a poor connection at one of the components. The prime suspect here is the clock spring in the steering wheel, aka "sliding contact" in the steering column behind the steering wheel. This provides power to everything in the steering wheel, inccluding the steering wheel position sensor. When this goes bad, it is tantamount to disconnecting and/or reconnecting the steering wheel position sensor. Fords are famous for sliding contact failure. Usually, you'll also have other issues with steering wheel components, such as the horn, cruise control, radio volume, air bag ("high resistence" OBD code), etc.
