What do you mean ? If ABS is non-functional then you will have a classic braking system on your hands (or under your foot). Pulling out the fuse will deactivate ABS system and your wheels will lock under hard breaking. If the fuse controls something else besides ABS then it may be a little harder to choose the "pull out" option -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
