ABS light constantly on

Hi I have 1998 5.7L and the abs light is constantly on, what can I check to turn it off, or is there a way to get a error code off of it or anything? I'm a brand new GMT400 owner and am loving and would like to keep my truck in tip-top shape? Any suggestions at all would be helpful.
