Ama-scanners nabafundi bekhodi bayamadivaysi ongawasebenzisa ukudonsa ulwazi oluwusizo ngaphandle kwekhompyutheni yebhodi okumele igcine imoto yakho isebenza kahle. Uma iyeka ukugijima kahle, ulwazi ongaluthola ngisho nomfundi wekhodi eshibhile lingenza kube lula ukwenza inqubo yokuxilonga. Futhi ezweni lamathuluzi wokuskena imoto kanye nabafundi bekhodi , i-OBD-I, emele i-Onboard Diagnostics I, iphathelene nokulula njengoba ithola.
Isiqalo Sokuhlola Nge-Onboard
Izimoto eziningi ezakhiwa ngaphambi kuka-1996 zisebenzisa isizukulwane sokuqala kuzinhlelo zokuxilonga ezibizwa ngokuthi yi-OBD-I. Izindlela zokuqala ze-OBD-I zibonise ngasekupheleni kweminyaka yama-1970 kanye nango-1980, kanti wonke umkhiqizi wakhetha ubuchwepheshe babo bokuxhumana.
Lokhu kusho ukuthi nakuba lezi zinhlelo zihlanganisiwe ndawonye kwisigaba esiphezulu se-OBD-I, babelana ngokuncane kakhulu. Wonke umkhiqizi wayenezibhamu zakhe ze-OBD-I eziyimfihlo, futhi ama-OBD-I amaningi ayenzelwe ukusebenza ngezimoto ezisuka kumuntu oyedwa noma ngisho nomodeli.
Isibonelo, isithwebuli se-OBD-I esenzelwe ukusebenza noxhumano lwe-GM's line-diagnostic link (ALDL) isixhumanisi ngeke isebenze noFeor noma uCrysler.
Izindaba ezinhle ukuthi, ezimweni eziningi, empeleni awudingi i-OBD-I scanner ukuze ufunde amakhodi. Izindaba ezimbi ukuthi wonke umkhiqizi wemishini yokuqala (OEM) wayenendlela yakhe yokufinyelela amakhodi ngaphandle kwamathuluzi okuxilonga , ngakho-ke isimo asiyona into elula.
Ukhetha kanjani i-OBD-I Scanner?
Ngokungafani ne-OBD-II scanners, isithwebuli se-OBD-I esisebenza ngokukodwa esisodwa ngeke sisebenze nomunye. Kodwa-ke, ezinye zalezi zithwebuli zenzelwe ukuba zenzeke emhlabeni wonke, noma okungenani zisebenze ngezenzo eziningi namamodeli.
Ama-scanner e-OBD-I e-OEM anezixhumi ezixhunyiwe kanzima kanye nesofthiwe ekwazi ukuxhumana kuphela namakhompiyutha avuliwe womkhiqizi oyedwa. Uma ungewona ochwepheshe bezimoto ezihamba phambili, ke ukubheja kwakho okuhle ukuthenga isithwebuli esithile se-OEM esizosebenza nemoto yakho. Lezi zithwebuli zilula ukuza kumasayithi afana ne-eBay, lapho ungayithola khona kahle kahle ngaphansi kwe $ 50.
Ama-scanners e-Universal futhi amaningi-OEM anezixhumi eziguquguqukayo nezesofthiwe ezingakwazi ukuphatha okungaphezu kokukodwa kwezimoto. Ezinye zalezi zithwebuli nazo zinama-cartridges noma amamojula aguquguqukayo avumela ukuba bashintshe phakathi kwama-OEM ahlukene.
I-OBD-I scanners esebenza nama-OEM amaningi ajwayelekile kakhulu ebiza kakhulu. Isibonelo, ungalindela ukukhokha kuma-dollar ayizinkulungwane eziningana ukuze isithwebuli esisebenza nazo zonke izinhlelo ze-OBD-I ne-OBD-II. Lokhu kuyindlela nje yokhetho lwabaqeqeshi abenza okuningi lolu hlobo lomsebenzi wokuxilonga.
Yini Engayenza I-OBD-I Scanner Do?
I-OBD-I-scanners ayinalo izici eziningi namakhono ama-scanner obD-II ngenxa yokulinganiselwa kwezinhlelo ze-OBD-I. Ngakho-ke, izici ezithile zanoma iyiphi isithwebuli zizoxhomeke kakhulu kulolu hlelo oluthile lwe-OBD-I olusebenzisana nabo njengoba luzokwenza ku-scanner ngokwayo. I-OBD-I scanners ngokuvamile ihlinzeka ukufinyelela okuyisisekelo kumifudlana yedatha, futhi ungakwazi ukufinyelela idatha yamafrimu efrijini, amatafula, nolwazi olufanayo.
I-OBD-I eyisisekelo kunazo zonke ezisemqoka zifana nabafundi bekhodi elula, ngoba konke abangakwenza bangamakhodi wokubonisa. Eqinisweni, lezi zitshalo eziyisisekelo ze-OBD-I empeleni azibonisi inombolo yenombolo. Esikhundleni salokho, bhanya ukukhanya okufanele ubale.
Amanye ama-scanner we-OBD-I angasusa amakhodi, futhi amanye akudinga ukuba ususe amakhodi ngenqubo eyisisekelo njengokunqamula ibhethri noma ukususa i-fuse ye-ECM.
Ukuhlanganiswa OBD-I / OBD-II Ukuhlola Amathuluzi
Amanye amathuluzi we- code kanye namathuluzi wokuskena ayakwazi ukubhekana nezinhlelo ezimbili ze-OBD-I ne- OBD-II . Lezi zithwebuli zihlanganisa isofthiwe engakwazi ukubhekana namakhompyutha angaphambi kuka-1996 aphuma kuma-OEM amaningi, isofthiwe engakwazi ukusebenzisana ne-post-1996 izinhlelo ze-OBD-II, nezixhumi eziningi zokubonisana nazo zonke ezingenhla.
Ochwepheshe bezobuchwepheshe bavame ukusebenzisa ama-scanner enhlanganisela angabhekana nakho noma yini, kodwa kukhona namadivaysi ebanga labathengi atholakalayo abalungile abakwa-DIYers abanomnikazi wezimoto ezindala nezindala.
Ukufunda Amakhodi Ngaphandle kwe-OBD-I Scan Ithuluzi
Izinqubo eziningi ze-OBD-I zihlanganisa ukusebenza okwakhiwe ngaphakathi okuvumela ukuthi ufunde amakhodi ngokuchofoza ukukhanya kwenjini yokuhlola, kodwa inqubo ihluka kusuka ku-OEM eyodwa kuya kwesinye.
I-Chrysler ingenye yezinto ezilula, njengoba konke okumele ukwenze ukuvula nokuvala izikhathi eziningana. Inqubo eqondile yilezi: ku-off, off, on, off, on, bese uyishiya, kodwa ungaqali injini. Ukukhanya kwe-injini yokuhlola kuyobe kukhanya ngokucacile ukukhombisa ukuthi yimaphi amakhodi agcinwe.
Isibonelo, enye ikhanya, ilandelwa ukuma isikhashana, ilandelwa ukukhanya okuyisikhombisa ngaphezulu kuzobonisa ikhodi 17.
Eminye yenza, njengeFree and General Motors, yinto encane kakhulu. Lezi zimoto zidinga ukuba ufinyelele ama-terminals esifushane kwisixhumi sokuxilonga, okuzokwenza ukuthi ukukhanya kwenjini yokuhlola kukhanyise amakhodi. Ngaphambi kokuba uzame ukufunda amakhodi kwenye yalezi zimoto, kuwumqondo omuhle ukubuka umdwebo wesiphatho sokuxilonga emotweni yakho ukuze uqiniseke ukuthi uthole ama-terminals afanele.
