My ABS light has turned on solid?

Hello, this is common when the ABS module goes out and causes the ABS control motor to stick on, can you hear a slight humming when the car is off? If so, I would trace the noise down to the ABS module under the hood. If you find the noise and are unsure of the part you are looking at, please upload an image so I can see what's going on, also, here is a guide that can help as well:
