ABS Light

My 96 K1500's ABS light has come on. For about a week it would turn on and off (seemed to come on in the afternoon-hot outside and be off in the morning). Now the light is on all the time. Is there anyway to diag this or what am I looking at for repairs? My local shop wants to charge me $99 to run a diag. :eek:

Thanks!

Does the 99 dollars include minor repair on it?
You need a ABS capable scanner to read out the abs data and run a diagnostic check on it and get codes.
It takes About 10 minutes to read codes and diagnostic data .
30 -50 minutes to fix/replace most minor problems like speed sensors.

If you can get the code no post it back for more info and help on it.
