Bled the Brakes Now ABS/Brake Light On

I believe you are missing the point that was being made: Nomenclature matters. It is a sensor that works with the tone ring on the differential carrier and not a switch. Try going to the parts store or searching an online parts store for a differential switch verses a VSS and see what you find.

in fact all most all newer fords it is actually called a ABS sensor and is located on top of the diff....

so now you're saying its not a ABS sensor, but a VSS something or another,
make up your mind.....
any idiot can take that part off the diff, clean it, re-install and 99% of the time the ABS light will go off.
reason?
because the sensor senses the difference in wheel speed which is tied into the ABS.

As stated in Post#12:
It's a vehicle Speed Sensor (VSS). It's a combined function on a 1993 F-series truck. The raw signal is for the RABS system. The buffered signal is used for the speedometer, computer (PCM), and the cruise control.

I am truly sorry you do not agree with the Ford service manual and now have launched a personal attack on my intelligence and integrity. I wish you the best in your endeavors. Please feel free to continue on with your insults, there is a reason why there is an Ignore List on this forum for folks like yourself. I have added you to mine, I highly suggest you do the same.

however when you cant comprehend what youre typing and think you know it all, its kind of like im talking to a brick wall.
its kind of like youre missing your own point.
that sensor on the diff is tied in somehow some way to the RABS system, and when it senses a difference in wheel speed the ABS light will come on, and if the sensor is bad, the ABS light will stay on.

I would agree because on newer Fords that sensor is used only for the ABS system. Not the case on the OP's 1993 F250.

Just wanted to say thank you - I use this site all the time for info on my trucks and I absolutely love it and appreciate everyone's input. I am posting because I had the EXACT same issue as the OP. I bled the brake system and didn't realize there was a RABS module. Both the ABS and Brake Lights were on (and not previous to the bleeding).
I fixed it by the bleeding the system once more, following the guide:
Actually, I bled the RABS first, and then went through 1 - 5 as quoted. Worked like a charm. I didn't problem solve the brake light first, but when I checked the float was working as it should (I don't know if it wasn't prior).
Anyhow, thank you once again.
