does the abs lights always lights on my gauge?

 

welcome to the forum, the abs light should go off after a scan when you turn your key on.If it stays on after your start, there is a problem with the abs system. Is your car under warranty? if so the dealer should fix it for no charge. If not under warranty, easy check is the brake fluid level, then for leaks at each individual brake unit, then for wear on the pads or linings. Also for debri in or around the brake area.
