94 Firebird ABS light

I am looking at buying a 94 Firebird with a 3.4L, 118K. ABS light is on. I know without having the car in front of you it might be tough. But what would be the most likely problem and/or fix. Just want to know if this would be a huge fix or if I should keep looking. Thanks!

typically an abs light isn't a huge problem.. it can be due to a dirty sensor etc... you may want to ask the owner when the last brake job was done
