ABS lite just came on on 1999 Ford F-150

Will the ABS lite coming on and not having the time to look after it cause some problem's until I can look into it.

The light means there's a fault in your anti-lock brake system, and it could be something as simple as a wheel speed sensor, or it could be a bit more severe. I recommend taking this to a shop for help as soon as you can, because brakes are a safety item.
