Ubwino ndi Zoperewera za Owerenga Buku
Owerenga galimoto ndi imodzi mwa zipangizo zosavuta zogwiritsira ntchito galimoto zomwe mungapeze. Zipangizozi zimakonzedwa kuti ziwonetsedwe ndi makompyuta a galimoto ndikufotokozera zizindikiro zosokoneza mwazomwe sizingatheke. Magalimoto ndi magalimoto omwe amamangidwa pasanafike chaka cha 1996 amafuna olemba enieni OBD-I, enieni, ndipo magalimoto atsopano amagwiritsa ntchito owerenga onse a OBD-II. Mtundu wamakono wa makasitomala a galimoto ndi wotchipa, ndipo mbali zina zimagulitsa ndi masitolo zikhoza ngakhale kuwerenga ma code anu kwaulere.
Kodi Galimoto Yopanga Buku la Owerenga Ili Bwanji?
Kulamulira kwa makompyuta kunayamba kuwonetsa pa magalimoto kumapeto kwa zaka za m'ma 1970 ndi kumayambiriro kwa zaka za m'ma 1980, ndipo machitidwewa anayamba kukula mofulumira. Ngakhale kuyang'anira makompyuta oyambirira kwambiri kunaphatikizapo "zoyambira" zomwe zimagwira ntchito, ndipo oyambirira, machitidwe ena OEM alionse amatchedwa OBD-I. Mu 1995, chaka cha 1996 chaka, odzimangirira padziko lonse lapansi anayamba kusinthika ku chikhalidwe chonse cha OBD-II, chimene chagwiritsidwa ntchito kuyambira nthawi imeneyo.
Zonse ziwiri za OBD-I ndi OBD-II zimagwira ntchito mofananamo, chifukwa zimayang'anitsitsa zochitika zosiyanasiyana zozizwitsa komanso zotsatira. Ngati dongosolo limatsimikizira kuti chinthu chili chonse, sichikhala ndi "kachilombo kovuta" kamene kangagwiritsidwe ntchito pofufuza njira. Chikho chilichonse chimagwirizana ndi vuto linalake, ndipo palinso mitundu yosiyanasiyana ya zizindikiro (ie, zovuta, zofewa) zomwe zimayimira mavuto omwe akuchitika komanso omwe amatha.
Pamene khodi la vuto likuyikidwa, chizindikiro chodabwitsa pa bolodichi chikuwunikira. Ichi ndi "nyali yosayendera magetsi" ndipo imangotanthauza kuti mungathe kuwerengera wowerenga galimoto kuti muwone vutoli. Inde, zizindikiro zina sizidzapangitsa kuwalaku kutsegulidwa.
Gawo lililonse la OBD liri ndi mawonekedwe ena omwe angagwiritsidwe ntchito kupeza zizindikiro. Mu OBD-Ine machitidwe, nthawi zina n'zotheka kugwiritsa ntchito chojambulirayi kuti muwone zizindikiro popanda owerenga magalimoto. Mwachitsanzo, ndizotheka kugwirizanitsa chojambulira cha ALDL cha GM ndikuyang'ana kuunika kwa injini yowunikira kuti mudziwe kuti ndondomeko ziti zaikidwa. Mofananamo, zizindikiro zingathe kuwerengedwa kuchokera ku magalimoto a OBD-I Chrysler potsegula makiyiwo ndi kutseka muyeso yapadera.
Muzinthu zina za OBD-I ndi machitidwe onse a OBD-II, zida zovuta zimawerengedwera podula kabuku kogwiritsa ntchito magalimoto ku OBD. Izi zimapangitsa owerenga kuti agwirizane ndi makompyuta a galimotoyo, kukoka zizindikiro, ndipo nthawi zina amachita zina zofunikira.
Kugwiritsa ntchito Car Code Reader
Kuti mugwiritse ntchito owerenga makhadi, ayenera kudula mu OBD. Mchitidwe uliwonse wa OBD-I uli ndi mawonekedwe ake, omwe angapezeke m'malo osiyanasiyana osiyanasiyana. Ogwirizanitsawa amapezeka nthawi zambiri pansi pa bokosi la fuse, koma akhoza kukhala pansi pa dash kapena kwinakwake. Mu magalimoto omwe anamangidwa pambuyo pa 1996, chojambulira cha OBD-II chimakhala pansi pa dash pafupi ndi chigawo cholowera. Muzochitika zosawerengeka, zikhoza kukhala kumbuyo kwa gululo, kapena ngakhale kumbuyo kwa ashtray kapena chipinda china.
Pambuyo pazitsulo za OBD zakhala zikugwiritsidwa ntchito, pulogalamu yamakono ya galimoto ikulumikizana ndi makompyuta a galimotoyo. Owerenga ndondomeko yosavuta amatha kukoka mphamvu kudzera mu mgwirizano wa OBD-II, zomwe zikutanthauza kuti kubudula wowerenga mkati kungathe kulimbitsa ndi kuwongolera. Panthawi imeneyo, mutha kutero:
- Werengani ndi kuchotsa ma code
- Onani Zomwe zimayambira
- Yang'anani ndipo mwinamwake mukonzanso kuyang'anira okonzekera
Zomwe mungasankhe zimasiyanasiyana kuchokera ku kampani imodzi ya ma galimoto kupita kumalo ena, koma mosakwanira muyenera kuwerenga ndi kuchotsa ma code. Inde, ndibwino kuti mupewe kufotokozera zizindikiro mpaka mutalemba, panthawi yomwe mungayang'ane pa chithunzi chovuta.
Kutsatsa K Code Code Reader
Ngakhale anthu owerenga magalimoto amakukondani pokupatsani njira yowunikira, vuto limodzi limakhala ndi zifukwa zosiyanasiyana. Ndichifukwa chake akatswiri odziwa zachipatala amagwiritsira ntchito zipangizo zamakono zomwe zimabwera ndi zidziwitso zowonjezereka komanso njira zogwiritsira ntchito. Ngati mulibe chida chomwe muli nacho, ndiye mutha kuwona chikhomodzinso cha vuto ndi kusokoneza chidziwitso pa intaneti.
ELM327 Vs Owerenga Zipangizo za Magalimoto
Zida zowonongeka za ELM327 ndizosiyana ndi owerenga makadi oyendetsa galimoto. Zipangizozi zimagwiritsa ntchito matekinoloje a ELM327 kuti agwirizane ndi dongosolo la OBD-II la galimoto yanu, koma alibe mapulogalamu, mawonetsedwe, kapena china chilichonse chimene owerenga chikhalidwe chawo ali nacho. M'malo mwake, zipangizozi zalongedwera kupanga mawonekedwe pakati pa piritsi, foni, laputopu, kapena chipangizo china, ndi makompyuta a galimoto yanu. Zowonongeka kwambiri zimakulolani kugwiritsa ntchito chipangizo cha ELM327 ndi foni yanu ngati owerenga malamulo, pomwe mapulogalamu apamwamba angakupatseni mawonekedwe amphamvu kwambiri.
