Probably not the module. ABS light generally means a sensor, but since you've stated you have a wobble in the left front wheel I'll assume the wheel bearing is bad. You'd have to check first. If your Brake light is illuminated too, probably just low fluid or the parking brake sensor is bad.
yup. if that front wheel bearing has that much slop then it is knocking the caliper piston back into the caliper every time you roll away from a stop then taking up that clearance again is like pushing the brakes down upon bleeding brakes.... so the light comes on. if it were a sensor then yeah it will pop both brake lights on, on the dash.
