Default pull the code?

Did you pull the code? Turn your key to the "on" position.... Hold the options button down and press the fuel button 4 times within 10 seconds to enter diagnostic mode.

There is a thread here somewhere that gives more detail on how to maneuver around in dignostic mode. Pulling the code is the first thing you need to do though.

Start here, this should help you find a code that should help you figure this out.

Are you getting warnings on the dash or the DIC?

Check the wheel speed sensors they may have come unpluged.

Looks like your front wheel sensors got whacked-check the plug at the wheels. The 1214 will shut off the AH/TC, see if you can get the 1221/1222 to go away 1st.

I am embarrassed to say this but I used a spray can to paint the calipers. Do u think that the sensors may have a little paint in them? The abs and ah stopped working the day after I painted the calipers

Probably got paint on the sensors themselves. Pull the rotors off and take a look around!

The sensors are VERY sensitive. Ever since I switched from wagon wheels to a much more open wheel, I have to be extra careful when driving through dirty roads. For example, I drove through a construction zone where I could hear gravel and chunks of soot flying around. Sure enough, my AH TC system shut off. All I needed to do was wash the car and give the hubs / wheels a good dousing, and I was fine. Same thing happened another time when I drove on a road with freshly melted snow, leaving salt and cinder all over the road. Sensor got dirty, threw a code, but was resolved by a good cleaning.
If that's not it, check your fuses and like someone else said, check the plug a the wheels.
