ABS Light on and off

My ABS Light keeps coming on and going Off on/off on/off and so on you get the picture I hope anyway. Do anybody know what might be causing this problem?

The light is giving you a trouble code. These probably can not be read at Autozone because they only read PCM codes(unless they changed recently). You need to have it scanned to have the trouble code read. Post back with code and we can help you in the repair. More than likely a speed sensor. Just don't know which one.
