IOBD-IIizibuko, ekwaziwa ngokuba yi-on-board diagnostic port, yinkqubo esemgangathweni esetyenziswa kwizithuthi zala maxesha ezakhiwa emva ko-1996. Eli zibuko lisebenza njengesango lokungena kulwazi loxilongo lwesithuthi, livumela amagcisa kunye nabanini ukuba babone iimpazamo kwaye babeke iliso kwimpilo yeenkqubo ezahlukeneyo zesithuthi.
Injongo ephambili ye-OBD-II port kukubonelela nge-interface esemgangathweni yokudibanisa izixhobo zokuxilonga kunye neeskena kwiyunithi yokulawula injini yesithuthi (ECU). I-ECU inoxanduva lokulawula nokubeka esweni ukusebenza kwe-injini, uthumelo, kunye namanye amacandelo abalulekileyo. Ukufikelela kwi-ECU nge-OBD-II port ivumela abachwephesha ukuba bafumane ulwazi oluxabisekileyo malunga nokusebenza kwesithuthi kunye nokuchonga nayiphi na imiba okanye ukungasebenzi.
Enye yezinto eziphambili zokusetyenziswa kwezibuko le-OBD-II kukuxilonga kunye nokusombulula iingxaki ezinxulumene ne-injini. Xa isibane esilumkisayo kwideshibhodi, esifana nesibane “sokukhangela i-injini” sikhanyisa, sibonisa ukuba kungakho ingxaki nge-injini okanye iinkqubo zayo ezinxulumeneyo. Ngesixhobo sokuxilonga esihambelanayo esixhunywe kwi-OBD-II port, ochwepheshe banokufunda iikhowudi zephutha ezigcinwe kwi-ECU kwaye banqume isizathu sengxaki. Oku kuvumela ukulungiswa ngokufanelekileyo, ngokuchanekileyo, ukunciphisa ixesha eliphantsi kunye neendleko kubanikazi bezithuthi.
Ukongeza kwiingxaki zokuxilonga, izibuko le-OBD-II linokubonelela ngedatha yexesha lokwenyani kwiiparamitha ezahlukeneyo ezifana nesantya senjini, ubushushu bokupholisa, ukusikwa kwepetroli, nokunye. Olu lwazi luluncedo kakhulu ekulungiseni ukusebenza njengoko luvumela abantu abanomdla ukuba babeke iliso kwaye baphucule ukusebenza kwesithuthi. Ukongezelela, i-OBD-II port yenza uvavanyo lokukhutshwa kwezinto ezikhutshwayo ngokubonelela ukufikelela kwiinkcukacha ezinxulumene nokukhutshwa, ukuqinisekisa ukuba isithuthi sihlangabezana nemigangatho efunekayo yokusingqongileyo.
I-OBD-II port ilula kakhulu inkqubo yokuxilonga kwaye yandisa ukusebenza kakuhle kokulungiswa kwezithuthi. Ngaphambili, oomatshini bekufuneka bathembele ekuhlolweni kwezandla kunye neenkqubo zokuvavanya ezinzima ukufumana iingxaki. Ngokusungulwa kwechweba le-OBD-II, amagcisa angakwazi ngokulula kwaye ngokukhawuleza abonise iimpazamo kwaye anike izisombululo ezichanekileyo.
Nangona kunjalo, kubalulekile ukuqaphela ukuba ngelixa i-OBD-II port inokubonelela ngolwazi oluxabisekileyo lokuxilonga, ayinikezeli isisombululo esicacileyo kuyo yonke ingxaki yemoto. Ingasebenza njengesiqalo sokuchonga iingxaki, kodwa uphando olongezelelweyo kunye nobuchule bunokufuneka ukuze kuxilongwe ngokupheleleyo kunye nokusombulula imiba entsonkothileyo.
Kwiminyaka yakutshanje, izibuko ze-OBD-II ziye zaba sisixhobo esibalulekileyo kubanini beemoto abafuna ukubeka esweni ukusebenza kwezithuthi kunye nokusebenza kakuhle kwamafutha. Izixhobo ezahlukeneyo ze-aftermarket kunye nee-apps ze-smartphone zinokuqhagamshela kwi-OBD-II port, ukubonelela ngedatha yexesha langempela malunga nemikhwa yokuqhuba, ukusetyenziswa kwepetroli, kunye neengcebiso zokuqhuba ukuphucula ukusebenza kakuhle.
Isishwankathelo, i-OBD-II port iyinxalenye yezithuthi zanamhlanje ezenziwe emva kwe-1996. Ivumela amagcisa kunye nabanini ukuba bahlolisise iimpazamo, ukubeka iliso ekusebenzeni kunye nokwandisa yonke inkalo yesithuthi sabo. Ngokubonelela nge-interface esemgangathweni, i-OBD-II port iphucula kakhulu ukulungiswa kwemoto kwaye ibe sisixhobo esibalulekileyo kwishishini leemoto. Nokuba isetyenziswa ngoochwephesha okanye abathanda, izibuko le-OBD-II lidlala indima ebalulekileyo ekugcineni isithuthi sakho sihamba kakuhle nangokufanelekileyo.
