ABS light is normally always on. If the light is off when the vehicle is first started and attempted to move it feels like the emergency brake is on then the ABS light kicks on and it drives fine.
Replaced abs unit, all brake components, and sensors....Still acted up (bind up and slide) so I disconnected the abs unit and it works fine
