So I get in my van and tried to drive but the rear brakes were stuck on so I give it more gas and bam it broke lose, the red brake light and the yellow abs light come on, brake fluid leaked on the ground at the right rear wheel, put it in the garage up on axle stands pulled off the tire and had to beat the drum off with a sledge hammer and found the wheel cylinder popped, changed it out along with new hardware kit, bled the brakes and the red light is out but yellow abs light still on, found corroded fuse and connector on the back side of the fuse box and cleaned it all up but light still on how do I check the system?

 

Oh yeh it's a 2002 dodge caravan 3.3 litre

 

You need a scanner to read the codes in the ABS module. You could have an open circuit in the rear wheels. But that's just a guess.
