IOBD-IIport, eyaziwa nangokuthi i-on-board diagnostic port, iwuhlelo olujwayelekile olusetshenziswa ezimotweni zesimanje ezakhiwa ngemuva kuka-1996. Leli chweba lisebenza njengesango lokufinyelela ulwazi lokuxilonga imoto, elivumela ochwepheshe nabanikazi ukuthi bahlole amaphutha futhi baqaphe impilo yemoto. amasistimu ahlukahlukene.
Inhloso enkulu yembobo ye-OBD-II ukuhlinzeka ngesixhumi esibonakalayo esimisiwe sokuxhuma amathuluzi okuxilonga nezikena kuyunithi yokulawula injini yemoto (ECU).I-ECU inesibopho sokulawula nokuqapha ukusebenza kwenjini, ukuhanjiswa, nezinye izingxenye ezibalulekile.Ukufinyelela i-ECU ngembobo ye-OBD-II kuvumela ochwepheshe ukuthi bathole ulwazi olubalulekile mayelana nokusebenza kwemoto futhi bahlonze noma yiziphi izinkinga noma ukungasebenzi kahle.
Okunye ukusetshenziswa okuyinhloko kwembobo ye-OBD-II ukuxilonga nokuxazulula izinkinga ezihlobene nenjini.Uma ukukhanya okuyisixwayiso kudeshibhodi, okufana nesibani “sokuhlola injini”, sikhanyisa, kubonisa ukuthi kungase kube nenkinga ngenjini noma amasistimu ayo ahlobene.Ngethuluzi lokuxilonga elihambisanayo elixhunywe embobeni ye-OBD-II, ochwepheshe bangafunda amakhodi amaphutha agcinwe ku-ECU futhi banqume imbangela yenkinga.Lokhu kuvumela ukulungiswa okusebenzayo, okunembile, ukunciphisa isikhathi sokuphumula kanye nezindleko zabanikazi bezimoto.
Ngokungeziwe ekuxilongeni izinkinga, imbobo ye-OBD-II ingaphinda inikeze idatha yesikhathi sangempela kumapharamitha ahlukahlukene njengesivinini senjini, izinga lokushisa elipholile, ukusikwa kukaphethiloli, nokuningi.Lolu lwazi luwusizo kakhulu ekucupheni ukusebenza njengoba luvumela abashisekeli ukuthi baqaphe futhi bathuthukise ukusebenza kwemoto.Ngaphezu kwalokho, ichweba le-OBD-II livumela ukuhlolwa kwe-emissions ngokunikeza ukufinyelela kudatha ehlobene ne-emissions, iqinisekisa ukuthi imoto ihlangabezana nezindinganiso ezidingekayo zemvelo.
Imbobo ye-OBD-II yenza kube lula inqubo yokuxilonga futhi ikhulise ukusebenza kahle okuphelele kokulungisa izimoto.Esikhathini esedlule, oomakhenikha bekumele bathembele ekuhloleni okwenziwa ngesandla kanye nezinqubo zokuhlola eziyinkimbinkimbi ukuze bathole izinkinga.Ngokwethulwa kwechweba le-OBD-II, ochwepheshe bangakwazi ukukhomba amaphutha kalula futhi ngokushesha futhi banikeze izixazululo ezinembile.
Nokho, kubalulekile ukuqaphela ukuthi nakuba imbobo ye-OBD-II inganikeza ulwazi olubalulekile lokuxilonga, ayinikezi isixazululo esiqondile kuzo zonke izinkinga zemoto.Kungaba isiqalo sokuhlonza izinkinga, kodwa kungase kudingeke olunye uphenyo kanye nobuchwepheshe ukuze kuxilongwe ngokugcwele futhi kuxazululwe izinkinga eziyinkimbinkimbi.
Eminyakeni yakamuva, amachweba we-OBD-II nawo abe yithuluzi elibalulekile kubanikazi bezimoto abafuna ukuqapha ukusebenza kwezimoto nokusebenza kahle kukaphethiloli.Izinhlobonhlobo zamadivayisi we-aftermarket nezinhlelo zokusebenza ze-smartphone zingaxhumeka kumbobo ye-OBD-II, zinikeze idatha yesikhathi sangempela ngemikhuba yokushayela, ukusetshenziswa kukaphethiloli, ngisho namathiphu okushayela ukuthuthukisa ukusebenza kahle.
Kafushane, ichweba le-OBD-II liyingxenye ebalulekile yezimoto zesimanje ezakhiwa ngemva kuka-1996. Ivumela ochwepheshe nabanikazi ukuthi bahlole amaphutha, baqaphe ukusebenza futhi balungiselele zonke izici zemoto yabo.Ngokunikeza isixhumi esibonakalayo esijwayelekile, ichweba le-OBD-II lithuthukisa kakhulu ukusebenza kahle kokulungisa izimoto futhi libe yithuluzi elibalulekile embonini yezimoto.Kungakhathaliseki ukuthi isetshenziswa ochwepheshe noma abathanda, imbobo ye-OBD-II idlala indima ebalulekile ekugcineni imoto yakho isebenza kahle nangempumelelo.
