Is the ABS working?
ASC is little sensors in the rear wheels that detect the wheel moving, when they detect that the wheel is spinning and no longer getting full grip, the little sensors send a message to the ECU to cut power to the wheels in several diff ways, can me by applying brakes or cutting fuel delivery to one cyclinde to retarding the timing ignition. The ASC has controls over the ABS and if anything fails with the ASC then your ABS can go aswel. The first thing to check would be your ASC sensors and ABS sensors. ABS sensors are cheap to replace and as far as i know, ASC are a little more money but still cheap.

But..........
If your ABS is working when braking hard, then its just the ABS bulb in the instrument cluster that needs replacing.

Hope this helps you!
