Izinzuzo kanye nokulinganiselwa kwabafundi bekhodi
Umfundi wekhodi yemoto ungenye yamathuluzi okuhlola imoto elula kakhulu ozothola. Lawa madivaysi aklanyelwe ukusebenzisana nekhompyutheni yemoto futhi abike amakhodi enkathazo ngendlela engafani neze-frills. Izimoto namaloli ezakhiwa ngaphambi kuka-1996 zidinga abafundi be-OBD-I abathile, abahamba phambili, futhi izimoto ezintsha zisebenzisa abafundi base-OBD-II emhlabeni jikelele. Lolu hlobo lokufunda ikhodi yemoto ngokuvamile alubizi, kanti ezinye izingxenye zigcina nezitolo zizofunda ngisho namakhodi akho mahhala.
Isebenza kanjani i-Code Code Reader Work?
Ukulawulwa kwekhompiyutha kwaqala ukubonakala ezimotweni ngasekupheleni kweminyaka yama-1970 kanye nasekuqaleni kwawo-1980, futhi lezi zinhlelo zakhula ngokushesha ekubunjeni. Ngisho nezinqubo zokulawula ikhompyutha zakuqala zazihlanganisa nokusebenza okuyisisekelo "ebhodini lokuhlola", futhi lokhu kusenesikhathi, izinhlelo eziqondene ne-OEM zibizwa ngokuthi yi-OBD-I. Ngonyaka we-1995, ngonyaka we-1996, ama-automakers emhlabeni jikelele aqala ukuguqula izinga eliphakeme le-OBD-II, eliye lasetshenziswa kusukela ngaleso sikhathi.
Zombili izinhlelo ze-OBD-I kanye ne- OBD-II zisebenza ngokufanayo ngendlela efanayo, ngoba ziqapha izinhlobonhlobo zemisindo nemiphumela. Uma isistimu inquma ukuthi noma yini ayifani, ibeka "ikhodi yenkinga" engasetshenziswa ezinkambisweni zokuxilonga. Ikhodi ngayinye ihambisana nephutha elithile, futhi kunezinhlobo ezahlukene zamakhodi (okusho kanzima, ezithambile) ezimele izinkinga zombili eziqhubekayo neziphakathi.
Uma ikhodi yenkinga isethiwe, isibonakaliso esikhethekile kudeshibhodi sivame ukukhanya. Leli "isibani sesibonakaliso sokungasebenzi kahle" futhi ngokuyisisekelo nje kusho ukuthi ungakwazi ukuhlanganisa umfundi wekhodi yemoto ukuze ubone ukuthi iyiphi inkinga. Yiqiniso, amanye amakhodi ngeke abangele lokhu kukhanya kuvulwe.
Njalo uhlelo lwe-OBD lunolwazi oluthile olungasetshenziswa ukuthola amakhodi. Ku-systems ye-OBD-I, ngezinye izikhathi kungenzeka ukusebenzisa lesi sikhangisi ukuhlola amakhodi ngaphandle komfundi wekhodi yemoto. Isibonelo, kungenzeka ukubhubhisa umxhumeli we-ALDL weGMM bese uhlola ukukhanya kwenjini ukukhanya ukucacisa ukuthi yimaphi amakhodi asethiwe. Ngendlela efanayo, amakhodi angasetshenziswa kusuka kwizimoto ze-OBD-I Chrysler ngokuvula ukhiye wokukhanyisa uphinde uvale iphethini ethile.
Kwezinye izinhlelo ze-OBD-I nazo zonke izinhlelo ze-OBD-II, izinkathazo zamakhodi zifundwa ngokufaka ikhodi yezimoto emotweni kwisixhumi se-OBD. Lokhu kuvumela umfundi wekhodi ukuthi abonisane nekhompyutha yemoto, adonse amakhodi, futhi ngezinye izikhathi enze imisebenzi embalwa eyisisekelo.
Ukusebenzisa i-Car Code Reader
Ukuze usebenzise umfundi wekhodi yemoto, kufanele ixhunyiwe kwisistimu ye-OBD. Uhlelo ngalunye lwe-OBD-I lunesixhumanisi sayo, esingatholakala ezindaweni ezahlukene ezahlukene. Lezi zixhumi zivame ukutholakala ngaphansi kwebhodi eliseduze nebhokisi lokufiphaza, kodwa zingase zibe ngaphansi kwedashi noma kwenye indawo. Ezitokisini ezakhiwa emva kuka-1996, isixhumi se-OBD-II sitholakala ngaphansi kwedashi eduze kwekholomu yokuqondisa. Ezimweni ezimbi, zingase zitholwe ngemuva kwephaneli kudatha, noma ngisho nangemva kwe-ashtray noma enye igumbi.
Ngemuva kokufakwa kwesitoreji se-OBD futhi kusetshenziswe ku-intanethi, umfundi wekhodi yemoto uzosebenzisana nekhomputha yemoto. Abafundi bekhodi elula bayakwazi ukudweba amandla ngokusebenzisa uxhumano lwe-OBD-II, okusho ukuthi ukuxhuma umfundi kungase kuqiniswe futhi kuwuguqule futhi. Ngaleso sikhathi, uzokwazi uku:
- Funda futhi usule amakhodi
- Buka ama-ID wamapharamitha ayisisekelo
- Hlola futhi mhlawumbe uphinde usethe kabusha abaqaphi bokuzilungiselela
Izinketho ezithile zihluka kusuka komunye umfundi wekhodi yemoto komunye, kepha okungenani kuncane kufanele ukwazi ukufunda nokususa amakhodi. Yiqiniso, kuwumqondo omuhle ukugwema ukususa amakhodi uze uwabhale phansi, lapho ungabheka khona eshadini lesikhuthazo.
Imikhawulo ye-Car Code Reader
Nakuba abafundi bekhodi yezimoto bekulungele ekunikezeni iphuzu lokuqhafaza kwenqubo yakho yokuxilonga, ikhodi eyodwa yenkathazo ingaba nenani lezimbangela ezihlukahlukene. Yingakho ochwepheshe bezoxilongo abasebenza ngokujwayelekile basebenzisa amathuluzi wokubheka okubiza kakhulu aneza nezinhlelo eziningi zokwaziswa kanye nezinqubo zokuxilonga. Uma ungenalo hlobo lwethuluzi onawo, khona-ke ungabheka ikhodi yenkinga eyisisekelo kanye nolwazi lokuxazulula inkinga ku-intanethi.
ELM327 Vs Abafundi bekhodi yeCom
Amathuluzi wokuhlola we-ELM327 ayindlela ehlukile kubafundi bokuqala bekhodi yemoto. Lawa madivaysi asebenzisa ubuchwepheshe be- ELM327 ukuze abonisane nesistimu ye-OBD-II yemoto, kodwa abanakho isofthiwe esakhelwe ngaphakathi, ukubonisa, noma yini enye umfundi wekhodi yendabuko enayo. Esikhundleni salokho, la madivayisi aklanyelwe ukuhlinzeka isikhombimsebenzisi phakathi kwethebhulethi, ifoni ehlakaniphile, i-laptop, noma enye idivayisi, kanye nekhompiyutha yakho. I-freeware eyisisekelo kakhulu izokuvumela ukuthi usebenzise ithuluzi lokuskena elingu-ELM327 kanye nefoni yakho njengomfundi wekhodi eyisisekelo, kanti isofthiwe esithuthukile kakhulu izokunikeza isikhombimsebenzisi esinamandla kakhulu.
