ABS light came on

hey guys, my ABS light just came on. i just got this its a 90 GS. are their any comon problumes i shuld look at first with the ABS system that would cause this light to go off? just to make my life a little bit easer… if any one has had their abs light come one was it the wheel speed sensor? ABS module? dirt in the sensor?.. Thanks for the help.

the most common problem for people with abs is known when they check the abs code. :search:

most common problem is probably dirty wheel speed sensor… but check the code first
