Indima yenzwa yokucindezela uwoyela ukuqapha umfutho kawoyela wenjini yemoto futhi idlulisele lolu lwazi kuyunithi yokulawula injini. Iyunithi yokulawula injini ilawula ukusebenza kwepompo likawoyela ngokuvumelana nesignali yengcindezi kawoyela eyamukelwe, ngaleyo ndlela iqinisekise ukusebenza okuvamile kwenjini. Uma umfutho kawoyela uphansi kakhulu, iyunithi yokulawula injini izolungisa ukusebenza kwephampu kawoyela ukuze ibuyisele umfutho kawoyela ebangeni elivamile. Uma umfutho kawoyela uphezulu kakhulu, iyunithi yokulawula injini izolungisa ukusebenza kwephampu kawoyela ukuvimbela ukushisa ngokweqile noma ukulimala kwenjini.

Inzwa yomfutho kawoyela ingakwazi ukubona isimo sokusebenza senjini ngokulinganisa umfutho kawoyela. Ivamise ukufakwa ohlelweni lokugcoba injini futhi ixhunywe empompini yamafutha. Uma injini isebenza, inzwa yomfutho kawoyela izozwa umfutho kawoyela bese iyiguqulela isignali kagesi ukuze idlulele eyunithi yokulawula injini. Iyunithi yokulawula injini inquma ukuthi ingcindezi kawoyela ijwayelekile ngokwesiginali kagesi eyamukelwe, futhi ithatha izinyathelo ezihambisanayo ukulungisa ukusebenza kwepompo likawoyela.

Lapho kuhlolwa inzwa yomfutho kawoyela, amathuluzi ochwepheshe okuxilonga angasetshenziswa ukuhlola ukuthi ingabe inzwa isebenza kahle yini. Ithuluzi lokuxilonga lingakwazi ukufunda isignali kusukela kunzwa ngokusebenzisa isixhumi esibonakalayo esixhunywe kunzwa kanye neyunithi yokulawula injini futhi lithole ukuthi ingabe inzwa ithola ngokufanelekile umfutho kawoyela. Uma kunenkinga ngenzwa, ithuluzi lokuxilonga lizobonisa ikhodi yephutha ehambisanayo ukuze izisebenzi zokunakekela zikwazi ukunquma ngokushesha imbangela yenkinga futhi zithathe izinyathelo ezifanele zokuyilungisa.
