Make sure that the module is bad and not the OVP relay which makes the ABS light go on too and is a very common fault. Also, a fault in any of the sensors can cause the light to stay on. The module is the most expensive part to replace in the system. You ought to easily find one from a recycler for a small fraction of the cost of a new one.
