The ABS light is telling you that there is a problem with the ABS system . Unless you have a personal scanner or take it to a professional to have it scanned , you won't know what the problem or trouble code is . Most auto part stores ( i.e.- Autozone , Advance , etc. ) will scan your vehicle for no charge . The ABS system is comprised of many complex and related pieces and since it's a very important safety item , it's best left to a professional to service it .
