I-Onboard Diagnostics II (OBD-II) yinkqubo echanekileyo yokuba iikhompyutha zihamba kwiimoto kunye namaloli zisebenzisa ukuxilonga kunye nokunika ingxelo. Le nkqubo inyuke kwimigaqo yeCaliber Air Resources (CARB), kwaye yaphunyezwa ngeenkcukacha ezenziwe nguMbutho weeNjini zeMoto (SAE).
Ngokungafani ngaphambili, iinkqubo ze-OD-I-OD-I, ii-OBD-II zisebenzisa iinkqubo ezifanayo zokunxibelelana, ukutyunjwa kweefowuni kunye nezixhuma ezivela kumenzi omnye ukuya kwenye. Oku kuvumela i-OBD-II eyodwa ukuba ikwazi ukufikelela kwiedatha ezi zikwazi ukubonelela ngazo zonke izinto kunye nemodeli yezithuthi eziveliswe ukususela ngo-1996, okwakungowokuqala umzekelo wokuba i-OBD-II iyadingeka ebhodini.
Iintlobo ze-OBD-II Scanners
Zikhona iindidi ezibalulekileyo ze-OBD-II zokuskena eziza kuzifumana kwintlango.
- Abafundi bekhowudi
- Abafundi bekhowudi ye-OBD-II ngokuqhelekileyo abanokungabibizi, ama-frills amacebo angakwazi ukufunda nokucima ikhowudi ukusuka nasiphi na isithuthi esine-OBD-II. Ezi zixhobo zinemiqathango embalwa ekungabikho kolwazi kwiinkcukacha ezithile kwaye zinikezela ngokukhawuleza (okanye akukho) ukufikelela kwenye idatha.
- Zixhobo zo ku khangela
- I-OBD-II zixhobo zokuskena zibiza kakhulu, kwaye zinokunikela ngeendlela ezahlukeneyo. Izixhobo zokukhangela zinokubonelela ngokubanzi okanye iinkcukacha malunga neendlela ezizenziweyo, ukubonelela ngokubanzi, ukufikelela ngokwezifiso zokuhlala kunye nokurekhodwa kwedatha kwaye unikeze ngolwazi oluphambili lweengxaki.
Yintoni enokuyenza i-OBD-II Scanner?
Umsebenzi we-scanner ye-OBD-II kuxhomekeke ekubeni ingaba "umfundi wekhowudi" okanye "isixhobo sokuskena" esiphambili. ukubonelela ngeziseko ezinzulu zolwazi, unikeze ukufikelela kwiimigaqo-mvavanyo kunye nezixhobo eziphambili.
Zonke izixhobo ze-OBD-II zokukhangela zinikeza umsebenzi othile oyintloko, oquka ukukwazi ukufunda nokucoca iikhowudi. Ezi zi-scanners nazo zinokunika ithuba lokujonga iilwimi ezilindileyo, okanye ezithambileyo, ezingazange zisebenzise ukukhanya kweenjini zokutshekisha okwangoku, kwaye zinikezela ukufikelela kwingcinezelo yolwazi. Idatha evela kuyo yonke inzwa eyenza igalelo kwikhompyutheni yebhodi ingabonwa nge-scanner ye-OBD-II, kwaye ezinye iiskena ziyakwazi ukuseta uluhlu lwezithethe ze-IDs (IDIDs). Ezinye i-scanners nazo zinikezela ukufikelela kumaziko okulinda kunye nolunye ulwazi.
I-OBD-II Work Scan?
Ekubeni iinkqubo ze-OBD-II zisezantsi, ii-scanners ze-OBD-II zilula ukuyisebenzisa. Bonke basebenzisa umxube omnye, ochazwa ngu-SAE J1962. Izixhobo zokuskena ezisisiseko zisebenza ngokufakela iplagi yendalo yonke kwi-OBD-II isixhobo sokuxilonga kwisithuthi. Ezinye izixhobo zokuhlola eziphambili zibandakanya izitshixo okanye iimodyuli ezongezela isixhobo sobuntu ukuze sifike okanye sisebenzisane nolwazi oluthe ngqo lwe-OEM okanye ulawulo.
Ukukhetha i-OBD-II Scanner eyiyo
Ukuba unayo imoto eyakhelwe emva ko-1996 kwaye wenza nayiphi na imisebenzi yomsebenzi kuyo, nokuba ugcine imali okanye ngenxa yokuba uthanda ukufumana izandla zakho zingcolile, isiskena se-OBD-II sinokubongeza kwinqanaba lebhokisi. Nangona kunjalo, loo nto ayithethi ukuba yonke i-mechanic ye-backyard imele ikhuphe ize ilahle i-$ 20,000 kwiziko eliphezulu lokuphenya kwi-Snap-on okanye kwi-Mac.
I-self-self-mechanics inokukhetha okuncinci kakhulu ukuhlolisisa, ngoko uya kufuna ukuyihlola phambi kokuba uthenge. Ngokomzekelo, ezininzi izityalo ziza kuhlolisisa iikhowudi zakho mahhala, kwaye unokufumana ulwazi oluninzi lokuxilongwa kwi-intanethi kwi-intanethi. Kwiimeko ezininzi, oko kungakho konke okufunekayo.
Ukuba ufuna ukuguquguquka kancinci, kukho inani elincinci lokukhethwa kwezixhobo onokuzijonga . Abafundi bekhowudi abazinikezeleyo nabo banikezela ukufikelela kwi-PID yinto enye yokujonga, kwaye unako ukufumana ixabiso elifanelekileyo phantsi kwama-$ 100. Enye inketho, ngakumbi ukuba unayo i-smartphone ehloniphekileyo ye-Android, yi- ELM 327 ye-Bluetooth scanner , eyona ndlela engancinci yokusebenza ngokufanayo.
