Jeep Grand Cherokee ABS light fix WHEN ALL ELSE FAILS

How to make ABS light come on then go out as it should when all is ok with the system.
This is obviously not an ABS fix just how to make it look like all is working on an offroad vehicle like mine. NOT TO BE USED ON VEHICLES USED TO DRIVE ON HIGHWAY
