Ever since I got my ranger, the check engine, check oil, and abs warning lights have been on. I've finally got around to fixing one of them. 
Last week I found out that I have been driving around with only front brakes since I got my truck last November.
I never noticed since I normally only commute three miles to work and sometimes around town.
The brake fluid level was fine, but no fluid was getting to the rear brakes.
It turns out one of the rear wheel cylinders failed and the previous owner didn't fix the problem. I guess that eventually the rabs module gummed up and the truck stopped loosing fluid.
So I replaced both wheel cylinders, brake pads, and the rabs module and the truck still had the abs warning light on. I found code 12 with the self diagnosis (low fluid level). I went to wiggle the wire connector at the master cylinder just for the hell of it and found that someone had connected it upside down.
Six hours of labor later, the ABS warning light is now out. I think I now have all four brakes working. I'll know tomorrow when I take it to work.
I wanted to thank everyone for this great forum. I don't think I would have fixed my truck without it.
What unexplained things have previous owners done to your vehicle?
