remove ABS light?
 

Can the ABS warning light on the dash be turned off with a tune?

There's no provisions for this in 86 through 93 that I'm aware of, and would think it is part of the body control module, and not engine management.

The light is controlled by the ABS module.

It's there to tell you something is wrong.

If you don't want to see it take the bulb out of the DIC.
