ABS Warning Light

ABS warning light has appeared and is staying on. What could be the cause and can I rectify the problem myself?

It means a fault has been detected by the ABS. Quite often it is a problem with a wheel sensor - some diagnostic tools can tell from the control unit which sensor it is, otherwise it is a case of connecting each sensor in turn to an oscilloscope and seeing if there is a signal there when the wheels are spun.

Thanks for that Spark123 but light has gone off again of its own accord.
