ABS light help

My abs light has started coming on and I really am not sure why. About a week ago my speedo acted up but now has been fine. The light started coming on after the speedo issue and after having put the truck in four wheel drive. Any input or help would be appreciated. I have been told I can ground that diagnostics pigtail from the ABS control module and get a code from the ABS light flashing. Anyone know about this or where the pigtail is.

no clue on the pig tail thing, but i would almost bet it is the speed sensor. try swapping that out, they are relatively inexpensive, if its not that, then go to the ABS module or wiring or even the fuses. i had the same issue on a different truck and it turned out to be both my sensor and control module. go the cheaper route first, it may be the right fix. let us know what you find out!

There is a rear speed sensor on the top of the pumpkin in your read end. About $25. One 10mm bolt I think. Loosen it and then pop it out. If that does not fix it, it maybe one of the front ones. They are a little more of a pain. You did to take it somewhere that can pull an ABS code. A normal code reader will not read it.

I don't think my truck has anything as far as speed sensors go on the front end. I believe is a rear only abs. I looked at the speed sensor on top of the rear axle. I will change it and see if that helps. Thanks.

Thumbs up ABS issue fixed

After reading the info from you guys I started to think for my self just a little and remembered that I have a full rear axle in my backyard from my 94' f-350 that I traded out for a gear ratio change. I stole the sensor off of it and put in on my 95' and that fixed it. Thanks for the help.
