so, i think it safe to assume that you topped off the low level fluid but the light is still on, right? DSC light and operation is directly tied to the ABS module, the speed sensors (inside wheel hubs), the yaw sensor (under center console), the level sensors (back and/or front) and the steering angle sensor... the operation is more electronic, and secondary to it, mechanical...

I am not saying that the two are not related, I am saying that it is less likely...
