if the abs and t/c off lights are on as well as the brake light. its a abs issue first. you'll need to hit a garage to get it scanned if you cant find a loose hub or bad wires to one of the hub, the free checks.

when the abs light comes on the magna steer quits working and the steering gets very firm to turn the wheel.

so one issue is two really. fix the abs and the steering will turn better.
