Isho ukuthini i-OBD?

 

OBDiwuhlelo oluqapha isimo sokusebenza kwezimoto futhi lunikeze impendulo ngesikhathi mayelana nokungajwayelekile, ikakhulukazi ukuqapha isimo senjini kanye nezimo zokuphuma kwemoto.Ezinsukwini zokuqala,OBDingabika kuphela ukwenzeka kwamaphutha ngendlela yezibani ezikhombisayo.Kamuva,OBDingabika idatha yesikhathi sangempela ehlukahlukene kanye namakhodi amaphutha ajwayelekile, okwenza izindlela zokuxilonga nezindlela zokulungisa amaphutha ezimoto zibe nezinguquko ezishintshayo.

 

Isistimu yokuxilongwa okuzenzakalelayo ye-onboard ingaphinda ihlole isimo sokusebenza sesistimu yokulawula i-elekthronikhi yenjini yemoto neminye imisebenzi eyisisekelo yemoto ngesikhathi sokushayela.Uma kunenkinga ngesistimu, ukukhanya kwe-Fault Warning Light (MIL) noma ukukhanya kwe-CheckEngine kuzokhanya, futhiOBDuhlelo luzogcina ulwazi lwenkinga kumemori.Ulwazi olufanele lungafundwa ngendlela yamakhodi amaphutha ngokusebenzisa amathuluzi okuhlola ajwayelekile kanye nezindawo zokuhlola.

 

Luyini uhlelo
