(ABS) light on Silverado 1997

[Slicer280]

The truck runs fine but just yesterday running down the highway the amber ABS light ( the only one) came on and will always stay on. upon ignition start it comes on naturally then goes out for a second then comes back on and stays on....my pump is not running when I shut the truck off I have 54k miles....any ideas.

Well the light is still on. I took it to get the codes read at the parts store..it came back with a successful read no errors.???? Could it be just a dirty sensor...I thought that would show up in the reading?
