Lub npe tag nrho ntawm OBD: On Board DiagnostIcs txhais ua Suav yog: On-board automatic diagnosis system" OBD Ⅱ" yog" ntawm Board DiagnosiTIcs Ⅱ", uas yog cov ntawv luv ntawm hom Ⅱ on-board diagnostic system. Txhawm rau ua tus qauv ntsuas kev kuaj mob ntawm lub tsheb emissions thiab kev ua txhaum ntawm kev tsav tsheb, pib txij xyoo 1996, txhua lub tsheb tshiab muag hauv Tebchaws Meskas yuav tsum muaj cov cuab yeej kuaj mob zoo sib xws, cov lej txhaum cai thiab cov txheej txheem tu, uas yog, ua raws li cov txheej txheem OBD II. Nrog rau kev nce qib ntawm kev lag luam thoob ntiaj teb kev lag luam thiab kev lag luam tsheb thoob ntiaj teb, OBD Ⅱ system yuav siv tau ntau dua thiab siv los ua lub hauv paus rau kev tsav tsheb thiab kev kuaj mob emission.
16 tus pin, txhua tus pin sawv cev rau qhov sib txawv, uas 1, 3, 8, 9, 11, 12, 13 yog cov chaw nres nkoj tsis siv, 2, 4, 5, 6, 7, 10, 14, 15, 16 yog siv lub interface. , zoo li 16 tus pin, tsuas yog muab cov khoom siv hluav taws xob lossis pom cov roj teeb hluav taws xob thiab tam sim no.
OBD cov cuab yeej saib xyuas ntau lub tshuab thiab cov khoom siv, suav nrog cov cav, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov pa oxygen sensors, emission tswj systems, roj systems, EGR, thiab lwm yam. . ECU muaj lub luag haujlwm ntawm kev kuaj xyuas thiab tshuaj xyuas qhov tsis raug cuam tshuam txog emissions.
Cov kev ceev faj:
Kev ua haujlwm ntawm OBD interface ntawm lub tsheb tuaj yeem cuam tshuam lub tsheb vim qhov tsis ua haujlwm ntawm cov khoom siv hluav taws xob sab nraud. Yog tias qhov zoo ntawm cov khoom siv hluav taws xob sab nraud tsis tsim nyog, lub zog hluav taws xob loj dhau, qhov tsis zoo thiab ua rau luv luv, thiab lwm yam, nws tuaj yeem hlawv OBD interface. Yog tias qhov tam sim no siab dhau lawm thaum lub sijhawm standby thiab OBD interface feem ntau txuas nrog hluav taws xob, lub roj teeb yuav ploj mus thiab lub tsheb yuav tsis tuaj yeem pib.
Sim tsis txhob txuas lwm yam khoom siv kho vajtse rau OBD interface. Cov cuab yeej sab nraud tsuas tuaj yeem nyeem cov ntaub ntawv ntawm lub computer mus ncig hauv OBD interface. Nws yeej muaj kev nyab xeeb tsis tuaj yeem sau cov ntaub ntawv, thiab kev nkag mus tsis raug cai yuav luag tsis yooj yim sua. Sim tsis txhob txuas cov khoom siv sab nraud, yog tias koj yuav tsum tau nruab nws, nws tsis yooj yim sua, tab sis koj yuav tsum xyuas kom meej tias qhov zoo tshaj.
