In most cases a constant ABS light is related to a bad wheel speed sensor or exiter ring which is attached to the half shafts on either side of the vehicle. The exciter ring looks like a gear with a bunch of teeth. That ring can crack or fall off. Check first and see if either is broken. While looking to you will see an electrical connection to each wheel. Follow to the end by the hub. It will have a pick up there that sometimes gets dirty or sometimes brake dust fills the grooves of the exciter ring. You cant get the codes read for the ABS at AutoZone so you might check these things first before spending money to have someone scan your ABS.
