Izibonelelo kunye nokulinganiselwa kwabafundi beMithetho
Umfundi wekhowudi yemoto enye yezinto ezilula zokuxilonga imoto oyifumanayo . Ezi zixhobo zenzelwe ukubonisana nekhompyutheni yemoto kwaye zibike iikhowudi zenkxalabo kwi-no-frills inhlobo yendlela. Iimoto kunye namaloli awakhiwe ngaphambi ko-1996 afuna abafundi abachanekileyo be-OBD-I, kunye neenqwelo ezitsha zokusebenzisa iincwadi ze-OBD-II ze-universal. Olu hlobo lomfundi wekhowudi yemoto luyinto engabizi, kwaye ezinye iindawo zigcina kunye neevenkile ziza kufumana iikhowudi zakho mahhala.
Usebenza njani Umgaqo-nkqubo weCare Reader?
Ulawulo lwekhompyutheni lwaqala ukubonakalisa kwiimoto ngasekupheleni kwee-1970 kunye neye-1980, kwaye ezi nkqubo zikhula ngokukhawuleza kwiinkathazo. Ngaphambi kokulawulwa kweekhompyutheni kwangoko kwakuquka isiseko "sokuhlola" ukusebenza, kwaye oku kwangaphambili, iinkqubo ezithile ze-OEM zibizwa ngokuba yi-OBD-I. Ngo-1995, kunyaka wama-1996, ii-automakers emhlabeni wonke zaqala ukutshintshela kumgangatho jikelele we-OBD-II, osetyenziswe ukususela apho.
Zomibini iinkqubo ze-OBD-I kunye ne- OBD-II zisebenza ngokufanayo ngendlela efanayo, ngokuba zijonga iindlela ezahlukeneyo zeziphumo kunye neziphumo. Ukuba le nkqubo inquma ukuba nayiphi na into engekho kwi-spec, ibeka "ikhowudi yenkathazo" engasetyenziswa kwiinkqubo zokuxilonga. Ikhowudi nganye iyahambelana nephulo elithile, kwaye kukho iintlobo ezahlukeneyo zekhowudi (oko kukuthi, nzima, ezithambileyo) ezimelele zombini iingxaki eziqhubekayo kunye neziphambili.
Xa ikhowudi yenkxalabo isetyenziswe, isalathisi esikhethekileyo kwideshibhodi iya kukhanya. Leli "isibonakaliso sesibonakaliso sokungasebenzi" kwaye ngokuqinisekileyo kuthetha ukuba unako ukumbamba umfundi wekhowudi yemoto ukuze ubone ukuba ingxaki yintoni. Ngokuqinisekileyo, ezinye iikhowudi aziyi kubangela ukuba lo kukhanya kuvule.
Yonke inkqubo ye-OBD inehlobo oluthile lwenxibelelwano olungasetyenziselwa ukufumana iikhowudi. Kwiindlela ze-OBD-I, ngamanye amaxesha kunokwenzeka ukusebenzisa lesi sixhobo ukujonga iikhowudi ngaphandle komfundi wekhowudi yemoto. Ngokomzekelo, kunokwenzeka ukutshintshela umxhasi we-ALDL we-GM kwaye uhlolisise ukukhanya kwe-injini yokukhangela ukujonga ukuba yeyiphi iikhowudi ezibekiwe. Ngendlela efanayo, iikhowudi ziyakwazi ukufundwa kwiimoto ze-OBD-I Chrysler ngokuguqula ukhiye wokutshisa kunye nokucima kwipatheni ethile.
Kweminye i-OBD-I kunye nazo zonke iinkqubo ze-OBD-II, iikhowudi zenkathazo zifundwa ngokuxhuma umfundi wekhowudi yemoto kwi-connector ye-OBD. Oku kuvumela umfundi wekhowudi ukuba asebenze kunye nekhompyutheni yemoto, ukukrazula iikhowudi, ngamanye amaxesha enze neminye imisebenzi embalwa.
Ukusebenzisa i-Car Code Reader
Ukuze usebenzise umfundi wekhowudi yemoto, kufuneka uxhonywe kwisistimu ye-OBD. Nganye Inkqubo ye-OBD-I inesiseko sayo, esinokufumaneka kwiindidi ezahlukeneyo zeendawo. Ezi zixhamli zifumaneka rhoqo phantsi kwebhodi elikufutshane nebhokisi lefestile, kodwa zingabonwa phantsi kwedash okanye kwenye indawo. Kwizithuthi ezakhiwe emva kowe-1996, umxhasi we-OBD-II uhlala phantsi kweedashsi kufuphi nekholamu yokuhamba. Kwiimeko zamatyala, ingafumaneka ngasemva kwephaneli kwideshi, okanye nangemva kwe-ashtray okanye enye igumbi.
Emva kokuba isiseko se-OBD sifumaneke kwaye sixhaswe, umfundi wekhowudi yemoto uya kubambisana nekhompyutheni yemoto. Abafundi bekhowudi abaqhelekileyo banako ukuthabatha amandla ngokusebenzisa uxhulumaniso lwe-OBD-II, oku kuthetha ukuba ukufakela umfundi kwi-intanethi kungayinamandla kwaye iguqule kwakhona. Ngelo xesha, uya kukwazi uku:
- Ukufunda nokucima ikhowudi
- Jonga ii-ID zeprayimeter eziphambili
- Hlola kwaye mhlawumbi uphinde usethe kwakhona abahlohli bokuzilungiselela
Izinketho ezithile zihluka kumfundi wekhowudi enye komnye umntu, kodwa ekungabalulekanga ubuncinane kufuneka ukwazi ukufunda nokucima ikhowudi. Ewe, yinto efanelekileyo yokuphepha ukukhupha iikhowudi uze uzibhale phantsi, apho usibheka khona kwididi yekhowudi yenkathazo.
Ikhowudi yeCom Code Reader Limitations
Nangona abafundi bekhowudi yomgaqo-mkhulu bakhulu ekunikeni ngephakamiso yokugxila kwinkqubo yakho yokuxilonga, ikhowudi enye yenkxalabo ingaba neyiphi inamba yezizathu ezahlukeneyo. Yingakho ochwepheshe bokuxilonga abaqeqeshiweyo basebenzisa izixhobo zokuhlaziya ezibiza kakhulu eziza kunye neendlela ezinzulu zolwazi kunye neenkqubo zokuxilonga. Ukuba awunalo hlobo lwesithuluzi olahlwayo, ngoko unokwazi ukujonga ikhowudi yeengxaki ezisisiseko kunye nolwazi lweengxaki kwi-intanethi.
ELM327 Vs Abafundi beCom Code Readers
I-ELM327 izixhobo zokukhangela zihlukile kwezinye zezifundo zeemoto eziphambili. Ezi zixhobo zisebenzisa i- ELM327 iteknoloji ukujongana nenkqubo ye-OBD-II yesithuthi sakho, kodwa abanakho isofthiwe esakhelwe kuyo, ukubonisa okanye nayiphi na into eyenziwa ngumfundi wenkqubo yendabuko. Endaweni yoko, ezi zixhobo zenzelwe ukubonelela isikhombiso phakathi kwethebhulethi, ifowuni ehlakaniphile, i-laptop, okanye enye idivayisi kunye nekhompyutheni yemoto yakho. I-freeware eyona siseko iyakuvumela ukuba usebenzise i-ELM327 ithuluzi lokukhangela kunye nefowuni njengomfundi wekhowudi oyintloko, ngelixa isofthiwe esiphezulu esongezelelekileyo izakukunika inxibelelwano enamandla ngakumbi.
