So on Christmas Eve I had to park outside on a hill for a couple hours and it was very cold. I put the parking brake on and when I tried to go home, my rear driver side wheel wouldn't spin and since there was a little snow, I couldn't move. I got a ride home and after some frantic searching on a possible cause, I found out that the parking brake freezing is a very common phenomenon among 2005 mustangs. So the next day, I crawled under the car with a hair dryer and spent a couple hours trying to thaw out the parking brake and after a while it loosen up enough to get it home. However, now the ABS light is on and the traction control is off with a “check traction control” prompt on the display. I tried to read the codes but it didn't find any. Some help and advice would be realty appreciated. Could I have ruined the ABS/Traction Control or a supporting sensor?
