Did you do you brakes recently? Cruise still work?
The sure fire way is for someone to tell you which sensor is acting up, some shops can pull ABS codes. . .which cost me $45 at the local midas.
Or the most common sensor failures (usually):
Master Cylinder switch (if failed, it should disable cruise control) was $20, $40 now? 30 second job, only channel locks required.
--if its not the above i'd take it in and get those codes read. -----
Rear ABS sensor on the Diff about $50 for the one, pia to swap out.
Fronts, take your pick about $70 each or $120 with bearing, don't guess at these like i did, lol, $400 later, still the ABS light. Then i had the codes read, and guess what, $20 and it was fixed.
