2006 Dodge Grand Caravan, ABS and Brake light

[The_Epsicle]

This isn't an urgent problem since the brakes still work, but on my moms 2006 Dodge Grand Caravan 3.3 V6 with a little over 100,000 miles on it the ABS and Brake light have come on solid, we've recently replaced the camshaft position sensor(a couple thousand miles ago) and the water pump, the light came on after replacing the water pump, we had to drop the engine a few inches to install the water pump so my thought was we might've torqued something on accident, but all the physical connections(hoses and electrical connectors) looked good. Here's the kicker, I had the codes read and the computer isn't putting out any codes for the ABS or brake system, actually there aren't any codes in any system at all. I figured it might just be an issue with the cluster so I took the car out to a gravel road at 40 mph and slammed on the brakes, and they locked up so the ABS system isn't working. No fuses blown, as far as I can tell the car is safe to drive. Just a weird problem.
