ABS lights and codes

Can someone please tell me what these codes are?
2012 Prius. All the Brake lights are on. Did the jumper method and pulled these codes:

ABS: 42
(!): 56
Slip: 45

thanks.

 

So this turns out to be the ABS booster pump, which is a very $$$ job. But I was told that this is covered by an enhanced warranty for certain vehicles. After 2 Dealerships basically laughed at me, I was able to secure the actually warranty in writing. The third Dealership said, yup... looks good, we will see you on Monday.
Major relief...
