Update 2: mechanic said the ABS code was C121D brake pressure sensor. which he says means it needs a new brake CPU for $600, does this sound right?
Update 1:
So I got the speed sensor for the rear diff to swap it out for $20 but when I climbed under the truck I saw oil leaking from the passenger side wheel. It's dripping down the rear of the brake drum shield. I'm thinking it's the rear seal on the hub. Would low diff fluid set off the traction control warning system???
The brake fluid level looks fine and no issues with the brakes as far as pressure goes. they have about half an inch of brake pad left all around. they were a little squeaky as I mentioned in my original post. I'm sure I would see brake fluid leaking at the line/caliper connection or from the piston/rotor not from the outside of the shield for the rotor.
Rear seal replacement video if this is the problem and people need this fixed 8n the future.

I'm traveling right now and don't have a chance to do some research. Family is visiting also and I'm pretty busy. So there's a button in the center console below the stereo that has the slippery Road symbol and has off and you can turn it off that symbol is in the bottom right-hand corner as if the roads snowy or icy. I tried to turn that off and I didn't do anything to turn off the slippery symbol. I think that my brakes need to be changed because they've gotten a little squeaky in the last couple days so I'm thinking there are low or worn down and I need to replace them. However with that symbol on I'm unable to click the cruise control set button. The cruise control symbol will turn on but I can't set a speed and we're on a road trip. So I'm thinking the truck is in some sort of mode for slippery roads because of the brakes and you can't set the cruise control in the instant if you are on ice or snow. Or maybe a fuse is bad somewhere??? I don't see a check engine light but haven't had a chance to scan the truck. And I haven't had a chance to look at the fuses. I just don't have the time at the moment so I'm hoping you guys can help me out a little bit and may know about this situation where the slippery symbol shows up and you cannot use cruise control and I don't you want to get a ticket so I prefer to use cruise control vs accidentally going a little fast. if anyone has any info let me know otherwise when I get a chance and the next few days I'll do a bunch of research and see if I can figure out what's going on. Thanks for your time sorry I didn't have a chance to look into this issue but I'm hoping you guys might know some information or of experience this situation and it might be a simple fix and when I get home I plan to do my brakes I don't feel the grinding sound of the little needle when you wear the breaks down in the little needle digs into the rotor so but they are pretty squeaky even after wearing off some rust from the morning moisture that occasionally I get on the pads when film of rust May build up if the truck sits in a moist environment and isn't driven for a few days seems like it squeaks so we're off that rust layer and then it won't squeak again but that was more so with an old Jeep I had I think these brake pads work pretty good and don't get that rust squeak layer in the mornings anyway let me know if you have any thoughts. Sorry about the rambling and the grammar this is all done with voice text.
