That last reply just confused me... like a hyundai behind a porche, I just don't follow!

The brake sensor is simply a sensor to alert you when the brakes have worn too thin and need to be replaced. The wheel sensors are wheel speed sensor that tells the dsc how fast that wheel is traveling, and all 4 wheels have them.

Unfortunately there is no way to properly diagnose and fix the DSC light being on without a proper diagnosis with fault codes read simply because it could be triggered by anything from a simple wheel speed sensor, a brake pressure sensor, fault in the hydrolic unit, wear to the wheel bearings causing false readings, bad DSC control unit, fault in communication between DSC and DME or EGS, etc, etc, etc.

I'd save myself the headache of throwing parts at it and pay the diagnosis fee at the dealer as they have the best equiptment to diagnose with.
