1991 rabs light

[turbo91xlt]

My '91 4x4 recently started having the rabs light coming on. When you hold the brake pedal to turn the truck on the light will be off. As soon as you let off the brake the light comes on and stays on. The brakes seem to work perfectly fine with no difference in feel compered to before the light coming on a few weeks back. Anyone have any suggestions? The only other time I've ever messed with rabs was when the rabs valve on my '92 ranger wouldn't let fluid go to the rear brakes. I just ended up bypassing it to fix that issue with that truck.

Check brake fluid level in Master, also the wiring connector on bottom of master.

Check that brake lights are working, my brake light fuse was blown and ABS light would come and go, was until someone pointed out no brake lights that I even knew.
After replacing fuse no more ABS light
