ABS light and traction signal stays on after bad battery, battery done, why? on 2007 Ford Explorer

does 2007 explorer have an ABS resovior that fluid goes in, and I have not checked 40 amp fuse

Asked by for the 2007 Ford Explorer
WHO installed the battery?
I did, the owner of the vehicle
See any sparks from the battery cables at any time when installing battery?
Now you are sure you didn't reverse the polarity just for an instant and blow a fuse????... Have the ABS scanned!
Thank You, will do ASAP
