    stubborn ABS warning light from hell
    its 1993, so its OBD 1
    no codes in the computer. when you hard wire the access port, the pump turns on and works.
    i have reset the computer every way i could think of. i even completely unplugged the ABS pump while resetting the computer.
    the light does not turn off!

    any suggestions before i put electrical tape over the warning light?

    the really messed up thing, is that it stops better when all the wheels lock... but i havent tested that on ice yet...

    Is the ABS fuse good?

    Also, did you reset your computer by disconnecting the battery? If not, you may want to give that a shot as well. I'm not sure if it works for ABS but it does for regular codes.

    fixed it
    wired ports A and H directly across
    hold for 2 seconds - hear the pump turn on - disconnect - repeat once more
    fixed
