Ukuxilonga Okusebhodini

I-OBD isifinyezo se-On-Board Diagnostic ngesiNgisi, futhi ukuhumusha kwesiShayina ngokuthi “On-Board Diagnostic System”.Le sistimu iqapha isimo sokusebenza kwenjini kanye nesimo sokusebenza sesistimu yokwelashwa kwegesi ephumayo ngemva kokwelashwa nganoma yisiphi isikhathi, futhi izokhipha isexwayiso ngokushesha uma kutholakala noma yisiphi isimo esingadala ukukhishwa kwegesi ngokweqile.Lapho uhlelo luwohloka, ukukhanya okungasebenzi kahle (MIL) noma injini yokuhlola (Injini Yokuhlola) kuyakhanya, futhi uhlelo lwe-OBD luzogcina imininingwane yephutha kumemori, futhi ulwazi olufanele lungafundwa ngendlela yephutha. amakhodi ngamathuluzi okuxilonga ajwayelekile kanye nezindawo zokuxilonga .Ngokusho kokwaziswa kwekhodi yephutha, izisebenzi ezinakekelayo zingakwazi ukunquma ngokushesha futhi ngokunembile uhlobo nendawo yephutha.

Izici ze-OBDII:

1. Umumo wesihlalo sokuxilonga semoto ehlanganisiwe ungu-16PIN.

2. Inomsebenzi wokudluliswa kwedatha yokuhlaziya izinombolo (IDATA LINK CONNECTOR, ebizwa ngokuthi i-DLC).

3. Hlanganisa amakhodi amaphutha afanayo nezincazelo zohlobo ngalunye lwemoto.

4. Ngokushayela umsebenzi rekhoda.

5. Inomsebenzi wokuphinda uveze ikhodi yephutha lememori.

6. Inomsebenzi wokusula ikhodi yephutha ngokuqondile ngethuluzi.

Amadivayisi e-OBD aqapha amasistimu nezingxenye eziningi, okuhlanganisa izinjini, iziguquli ze-catalytic, izicupho zezinhlayiya, izinzwa zomoya-mpilo, amasistimu okulawula ukungcola, amasistimu kaphethiloli, i-EGR, nokunye.I-OBD ixhunywe kuyunithi yokulawula ye-elekthronikhi (ECU) ngolwazi oluhlukahlukene lwengxenye ehlobene nokukhipha umoya. , futhi i-ECU inomsebenzi wokuthola nokuhlaziya amaphutha ahlobene nokukhipha umoya.Uma kwenzeka ukwehluleka kokukhipha, i-ECU irekhoda ulwazi lokwehluleka namakhodi ahlobene, futhi ikhiphe isexwayiso ngokukhanya okuhlulekayo ukwazisa umshayeli.I-ECU iqinisekisa ukufinyelela nokucutshungulwa kolwazi olunephutha ngokusebenzisa isixhumi esibonakalayo sedatha.
