Lalacewar firikwensin ABS ya haɗa da hasken ABS akan dashboard, ABS baya aiki yadda ya kamata, da kuma kunna hasken sarrafa jan hankali. Waɗannan gazawar na iya faruwa ne sakamakon lalacewa, yankewa, ko kuma tarkace ya same su. Musamman firikwensin ABS na ƙafafun baya, idan tarkacen ƙarfe da aka samar ta hanyar niƙa faifan birki da faifan birki sun shanye ta hanyar maganadisu, na iya haifar da nisan da ke tsakanin firikwensin da na'urar maganadisu ta yi ƙanƙanta, ko ma lalacewa, daga ƙarshe ya haifar da lalacewar firikwensin.
Domin a tantance ko na'urar firikwensin ABS ta lalace, ana iya gano ta ta hanyoyi masu zuwa:
Karanta lambar laifin kayan aikin gano lahani: Idan akwai lambar kuskure a cikin kwamfutar ABS, kuma hasken laifin akan kayan aikin yana kunne, wannan na iya nuna cewa na'urar firikwensin ta lalace.
