Scanners thiab code readers yog cov cuab yeej siv uas koj tuaj yeem siv los rub tawm cov ntaub ntawv tawm ntawm lub computer onboard uas yuav tsum ua kom koj lub tsheb khiav khov kho. Thaum nws nres tsis ruaj khov kho, cov ntaub ntawv koj tuaj yeem siv nrog tus tseem pheej yoojyim code nyeem tau yooj yim rau cov txheej txheem tshawb nrhiav. Thiab nyob rau hauv lub ntiaj teb ntawm lub tsheb scan cov cuab yeej thiab cov neeg nyeem nyeem , OBD-Kuv, uas yog rau Onboard Diagnostics Kuv, yog li yooj yim li nws tau txais.
Pib ntawm Diagnostics Onboard
Feem ntau cov tsheb uas tau tsim ua ntej xyoo 1996 siv thawj lub cim onboard diagnostic systems uas yog sau ua ke hu ua OBD-I. Thawj cov kab mob OBD-I tau tshwm sim hauv lub xyoo 1970 thiab 1980s, thiab txhua lub khw tsim lawv tus kheej cov cuab yeej technology.
Qhov ntawd txhais tau hais tias thaum lub sijhawm no ua ke ua ke hauv OBD-I, feem ntau lawv tsuas sib koom ua ke. Txhua lub khw muaj nws, OBD-I plugs thiab jacks proprietary, thiab ntau OBD-I scanners tau tsim los ua haujlwm nrog cov tsheb los ntawm tsuas yog ib qho tsim lossis qauv txawm.
Piv txwv li, ib qho OBD-I scanner uas tau tsim los ua haujlwm nrog GM's sibtham tshawb nrhiav kev txuas (ALDL) txuas yuav tsis ua haujlwm nrog Ford lossis Chrysler.
Qhov xwm zoo yog tias, feem ntau, koj tsis tau xav tau OBD-I scanner los nyeem cov ntawv. Cov xov xwm tsis zoo yog tias txhua lub chaw tsim khoom siv (OEM) tau nws tus kheej txoj kev nkag mus rau cov cai tsis muaj cov cuab yeej tshawb nrhiav , vim li ntawd qhov teeb meem yog txhua yam tiam sis yooj yim.
Koj Yuav Xaiv Tus OBD-I Scanner Li Cas?
Tsis zoo li OBD-II scanners, ib qho OBD-I scanner uas ua haujlwm nrog ib qho ua tsis tas yuav mus ua haujlwm nrog lwm tus. Txawm li cas los xij, ib txhia ntawm cov luam yeeb no yog tsim los ua kom muaj universal, los yog tsawg kawg ua haujlwm nrog ntau yam ua thiab ua qauv.
OEM-OBD-I scanners tau sib txuas cov hlua khi thiab software uas tsuas yog muaj peev xwm sib txuas nrog cov computers hauv computer ntawm ib lub chaw tsim tshuaj. Yog tias koj tsis yog ib tug kws tsav tsheb, ces koj qhov thawj koom ruam zoo tshaj yog mus yuav OEM ib qho scanner uas yuav ua haujlwm nrog koj lub tsheb. Cov scanners yog ib qho yooj yim los ntawm cov chaw xws li eBay, qhov twg koj tuaj yeem pheej nrhiav tau ib qho zoo rau hauv $ 50.
Universal thiab Multi-OEM scanners muaj kev sib txuas sib txuas thiab software uas muaj peev xwm ua tau ntau tshaj ib lub tsheb. Qee cov ntawm cov scanners no kuj muaj cov khoom siv sib txuas los yog cov khoom siv uas lawv hloov ntawm cov OEMs sib txawv.
OBD-Kuv lub tshuab luam yeeb uas ua haujlwm nrog ntau cov OEMs feem ntau kim kim. Piv txwv li, koj tuaj yeem cia siab them nyiaj txog li ob peb txhiab daus las rau lub tshuab hluav taws xob uas ua haujlwm nrog tag nrho cov OBD-I thiab OBD-II systems. Qhov no tsuas yog qhov kev xaiv rau cov tub txawg uas ua ntau hom kev tshawb nrhiav haujlwm no.
Qhov OBD-I Scanner Ua Tau Dab Tsi?
OBD-I scanners tsis muaj ntau cov qauv thiab cov peev xwm ntawm OBD-II scanners vim cov kev txwv ntawm OBD-I systems. Raws li, qhov nta ntawm cov scanner yuav vam khom kom ntau npaum li ntawm OBD-I system uas koj tabtom soj ntsuam nrog lawv raws li ntawm cov khoom scanner xwb. OBD-I scanners feem ntau muab kev nkag yooj yim rau cov ntaub ntawv ntws, thiab koj tuaj yeem muaj peev xwm nkag tau cov ntaub ntawv khov, cov ntxhuav, thiab cov ntaub ntawv zoo sib xws.
OBD-I scanners yooj yim tshaj plaws yog zoo li cov nyeem yooj yooj yim, vim tias txhua yam lawv ua tau yog cov yeeb yaj duab. Qhov tseeb tiag, cov tshuab luam yeeb OBD-I no tsis tau tso tawm tus nab npawb code. Xwb, lawv ntsais lub teeb uas koj tau suav.
Muaj qee tus luam cov OBD-kuv tau thim tau cov lis dej num, thiab lwm tus xav kom koj lwv cov cim nrog txoj hau kev yooj yim xws li disconnecting lub roj teeb los yog tshem tawm cov ntawv foob ECM.
Kev Sib Cuam Tshuam OBD-I / OBD-II Cov Cuab Yeej Siv Hluav Taws Xob
Qee cov nyeem cov ntawv nyeem thiab cov cuab yeej scan muaj peev xwm ua haujlwm nrog ob lub tshuab OBD-I thiab OBD-II . Cov scanners muaj xws li software uas tuaj yeem ua haujlwm nrog pre-1996 onboard computers los ntawm ntau cov OEMs, software uas muaj peev xwm sib txuas tau nrog rau kev sib tham nrog 1996-OBD-II, thiab ntau yam txuas mus rau txhua qhov ntawm cov saum toj no.
Cov kws tshaj lij siv feem ntau siv cov tshuab luam ntawv ua ke nrog rau txhua yam, tab sis kuj muaj cov neeg siv khoom siv pabcuam uas muaj zoo rau DIYers uas muaj ob qhov qub thiab cov tsheb tshiab.
Cov Kev Cai Nyeem Ntawv Tsis muaj OBD-I Scan Tool
Feem ntau cov kab mob OBD-kuv muaj xws li ua haujlwm hauv vaj hauv tsev uas tso cai rau koj nyeem cov lis dej los ntawm qhov muag ntsig cav, tab sis cov txheej txheem txawv ntawm OEM mus rau lwm qhov.
Chrysler yog ib qho yooj yim, vim txhua yam koj yuav tsum ua yog tig qhov tseem ceeb tiv thaiv rau thiab tawm ob peb zaug. Tus txheej txheem pes tsawg yog: rau, tawm, tawm, tawm, tawm, thiab ces tawm hauv, tab sis tsis txhob pib lub cav. Qhov kev tshawb xyuas lub teeb lub cav yuav ces ntsais kom qhia tias cov cim tseg cia.
Piv txwv li, ib qho ntsais muag, ua raws li lub caij luv luv, tom qab los ntawm xya ntau blinks yuav qhia ib txoj cai 17.
Lwm yam ua, zoo li Ford thiab General Motors, yog me ntsis nyuab dua. Cov tsheb no xav kom koj mus luv luv hauv cov chaw kuaj mob, uas yuav ua rau lub cav kuaj lub teeb kom ntsais tawm cov cim. Ua ntej koj sim nyeem cov ntawv ntawm ib qho ntawm cov tsheb no, nws yog ib lub tswv yim zoo kom nrhiav tau daim duab ntawm lub chaw kuaj mob ntawm koj lub tsheb kom paub tseeb tias koj tau txais txoj cai terminals.
