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.

Cheapest option would be to have the fault code read by a dealer or specialist. Its likely to be a wheel speed sensor but its finding which one that's the problem. You could disconnect each one and take an ohms reading across the connections. They should all be the same or there abouts. Change the one thats not. If your lucky the light may extinguish. If not the fault will need to be cleared using diagnostic equipment.

The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

check for something stuck in the wheels and as for the coolant light get the car running and up to warm temp and start adding coolant to the reserviour bottle until it is up to hot level because there maybe a bubble in the line but also if might be a bad switch in the reservior bottle itself

It is a fault with the ECM . It will have to be test with machine

My traction control light stays on in my 2002 Mercury Sable. I push the shut-off button but the light still stays on.
