If you only have rear wheel antilock, inspect the rear brakes, including the line running back there. If all looks well, replace the sensor.

If you have 4wal, you will probably have to take it in to a shop to have the codes read, as the parts stores won't do it.

 

Well bled brakes again and did not get any air out. Replaced sensor today with a Borg Warner sensor. The light is now out and fixed problem. Thanks for all the help!
