Abacwaningi nabafundi bekhowudi zixhobo onokuzisebenzisa ukutsala ulwazi oluncedo ngaphandle kwikhompyutheni yebhodi ekufuneka ugcine imoto yakho isebenza kakuhle. Xa iyeka ukuhamba kakuhle, ulwazi onokuyibamba kunye ne-reader code encinci lingenza lula ukwenza inkqubo yokuxilonga. Kwaye kwihlabathi lezinto zokukhangela imoto kunye nabafundi bekhowudi , i-OBD-I, emele i-Onboard Diagnostics I, inokulula njengoko ithola.
Ukuqala kwee-Diagnostics kwi-Onboard
Uninzi lwezithuthi ezenziwe ngaphambi kowe-1996 zisebenzisa isizukulwana sokuqala kwiinkqubo zokuxilongwa ezibizwa ngokuba yi-OBD-I. Iimpawu zokuqala ze-OBD-I zibonakaliswe ngasekupheleni kwee-1970 kunye nakwiminyaka ye-1980, kwaye bonke abakhiqizi bavelisa ubuchwepheshe babo bobuchwepheshe.
Oko kuthetha ukuba ngelixa iisistimu zidibene ndawonye kwisigaba esiphezulu se-OBD-I, babelana ngokuncinane kakhulu. Yonke into eyenziwa yi-OBD-I iplagi kunye ne-jack, kwaye ezininzi ze-OBD-I zenzelwe ukusebenza kunye neenqwelo zenziwe kuphela okanye zenze imodeli.
Ngokomzekelo, i-OBD-I-scanner eyenzelwe ukusebenza kunye nekhonkco ye-GM yomgca wokuxilonga (ALDL) ayiyi kusebenza noFeor okanye uCrysler.
Iindaba ezilungileyo kukuba, kwiimeko ezininzi, ngokwenene awufuni i-OBD-I-scanner ukufunda iikhowudi. Iindaba ezimbi kukuba zonke izixhobo zokuqala zezixhobo (i-OEM) zineendlela zayo zokufikelela kwiikhowudi ngaphandle kwezixhobo zokuxilonga , ngoko imeko ayikho into elula.
Ukhetha njani i-OBD-I Scanner?
Ngokungafani ne-OBD-II scanners, i-OBD-I-scanner esebenza kunye nokwenza enye ayiyi kusebenza kunye nomnye. Nangona kunjalo, ezinye zala ma-scanners zenzelwe ukuba ziphela jikelele, okanye ubuncinane zisebenze ngeendlela ezininzi kunye nemizekelo.
I-OD-I-scanners ye-OBD-I ine-connectors ene-hard-wire kunye nesofthiwe ekwazi ukudibanisa kunye neekhomputer zekhompyutha zomenzi omnye. Ukuba awuyena ochwephesha wobuchwephesha, ububhetri bakho obufanelekileyo kukuthenga umtshini ocacileyo we-OEM oza kusebenza kunye nemoto yakho. Ezi zi-scanners zilula ukuza kumaziko anjenge-eBay, apho ungasifumana khona ngaphantsi kwe $ 50.
Iiskrini ze-Universal kunye ne-Multi-OEM zinezixhobo ezidibeneyo kunye nesofthiwe ekwazi ukuphatha ngaphezulu kweyodwa yezithuthi. Ezinye zala ma-scanners nazo zineekhodijiji okanye iimodyuli ezivumela ukuba batshintshe phakathi kwee-OEM ezahlukeneyo.
I-OBD-I-scanners esebenzayo nama-OEM amaninzi ngokuqhelekileyo ayabiza kakhulu. Ngokomzekelo, unokulindela ukuhlawula kumawaka angamawaka eedola kwi-scanner esebenzayo nayo yonke inkqubo ye-OBD-I kunye ne-OBD-II. Oku kuyona kuphela inketho kubaqeqeshi abenza oluninzi lolu hlobo lo msebenzi wokuxilonga.
Yintoni enokuyenza i-OBD-I Scanner Do?
I-OBD-I-scanners ayinalo ezininzi iimpawu kunye nobuchule be-scan-OBD-II ngenxa yemida ye-OBD-I systems. Ngako oko, iimpawu ezithile ze-scanner ziya kuxhomekeka kakhulu kwi-OBD-I inkqubo ejongene nayo njengoko bayakuyenza kwi-scanner ngokwayo. I-OBD-I-scanners ngokuvamile inikeza ukufikelela okuyisiseko kwimifudlana yedatha, kwaye unokukwazi ukufikelela kwi-fram-frame frame, iitafile kunye nolwazi olufanayo.
I-BASD-I i-scanners ebaluleke kakhulu ifana nabafundi bekhowudi elula, ngokuba konke abakwenzayo kukubonisa ikhowudi. Enyanisweni, ezi ziphambili ze-OBD-I zitshintshi azibonisi ngokwenani ikhowudi. Esikhundleni saloo nto, baqhawula ukukhanya okufuneka ubale.
Ezinye i-OBD-I i-scanners iyakucima iikhowudi, kwaye abanye bakudinga ukuba ususe iikhowudi kunye nenkqubo eyintloko njengokunqakraza ibhetri okanye ukususa i-fuse ye-ECM.
Umxube OBD-I / OBD-II Izixhobo zokukhangela
Abanye abafundi bekhowudi kunye nezixhobo zokuskena zikwazi ukujongana neenkqubo ze-OBD-I kunye ne- OBD-II . Ezi zi-scanners ziquka iprogram engakwazi ukujongana ne-1996 yangaphambili kwiikhompyutha ezivela kwii-OEM ezininzi, isofthiwe engakwazi ukusebenzisana neenkqubo ze-OBD-II zangemva kwe-1996, kunye nezixube ezininzi zokubonisana nazo zonke ezi ngasentla.
Ochwepheshe bezobuchwephesha basebenzisa ama-scanners anxulumene nawo anokujongana nayo nayiphi na into, kodwa kukho iikhompyutha zamabhanki ezikhoyo ezifanelekileyo ezilungiselelwe ii-DIYers ezithatha izithuthi ezidala kunye nezitsha.
Iikhowudi zokuFunda Ngaphandle kwe-OBD-I-Scan Tool
Iinkqubo ezininzi ze-OBD-I ziquka ukusebenza okwakhiwayo okukuvumela ukuba ufunde iikhowudi ngokukhanyisa ukukhanya kweenjini, kodwa inkqubo iyahluka kwi-OEM enye.
I-Chrysler yenye yezona zinto zilula, njengoko konke okufuneka ukwenze ukuguqula iqhosha lokubilisa kunye nokucima amaxesha amaninzi. Inkqubo echanekileyo yile: ku-off, ku-off, ku-off, kwi-, kwaye uyishiye, kodwa ungaqali injini. Ukukhanya kweenjini zokutshekisha kuya kubonakalisa ukubonisa ukuba ziphi iikhowudi ezigcinwe.
Ngokomzekelo, enye i-blink, ilandelwa ikhefu elifutshane, elilandelwa zizihlwele ezisixhenxe ziza kubonisa ikhowudi 17.
Enye yenza, njengeForne neGeneral Motors, yinto encinci ngakumbi. Ezi zithuthi zifuna ukuba uphume ixesha elifutshane kwisixhobo sokuxilonga, esiza kubangela ukukhanya kweenjini ukukhangela iikhowudi. Ngaphambi kokuba uzame ukufunda iikhowudi kwenye yezithuthi, yinto efanelekileyo ukujonga umzobo wesixhakaxhaka sokuxilonga kwimoto yakho ukuqinisekisa ukuba ufumana iipedali ezifanelekileyo.
