First of all, do a search on this board for ABS. There a lot of good posts on this topic.
Is the brake light on too? I had my rear brake cylinders fail, (after replacing shoes) leak fluid thus causing an uneven presure on the system (low in the rear) and turning on the brake light.
As for testing the sensors, you can do this with an OHM meter. At the moment I don't have a manual infront of me, however, I know the front and rear are different values. If you test both rear, they should have very close values. Same for the front. If they test to be the same test the wire to the control. They too should have simular readings on the front wheels and back wheels.
How long has this light been on? Did you have work done reciently?
