Best Answer.They could only reset the codes. The ABS can never be disabled. The only things that are disabled by your button on the ceiling are the Stabilitrac and Traction control, and those are automatically turned back on every time you restart the car.
Having one or two tires that are significantly different in size could quite likely have triggered the message, just as hitting potholes or bumps while braking will do the same thing.
I don't think there is any problem here. It is not a coincidence that you got the warning after moving the car before changing all four tires. Did you happen to mention any of this activity to the dealer?
