First.. Unless a death is involved, I seriously doubt there'd be any forensic dissection of the vehicle in the event of an accident regarding the abs system. That said, with the system disabled, regardless of whether intentional or not, you are serious limiting your stopping distance in most scenarios. You're better to fix it than wasting effort to delete it. The person you save from needing new teeth, going through the windshield or requiring cosmetic surgery just might be you!
Just sayin...
Have a nice day!
