Aluphumelelanga uvavanyo lokukhutshwa kweMisi ? Lungisa iikhowudi ezili-10 eziqhelekileyo ze-OBD-II ngaphambi koHlolo lwakho olulandelayo

Izithuthi zala maxesha zixhomekeke kwi-On-Board Diagnostics II (OBD-II) inkqubo yokubeka iliso ekusebenzeni kweenjini kunye nokukhutshwa kwezinto ezikhutshwayo. Xa imoto yakho ingaphumeleli kuvavanyo lokukhutshwa, i-OBD-II yokuxilonga izibuko iba sisixhobo sakho esilungileyo sokuchonga kunye nokusombulula imiba. Ngezantsi, sichaza indlela i-OBD-II scanners esebenza ngayo kwaye ibonelele ngezisombululo kwiikhowudi zeengxaki eziqhelekileyo ezili-10 ezinokubangela ukusilela kokukhutshwa.

IiSkena ze-OBD-II ziNceda njani ukufumanisa imiba yokuPhuma

  1. Funda iiKhowudi zeNgxaki yokuDinga (i-DTCs):
    • Izikena ze-OBD-II zifumana kwakhona iikhowudi (umz., P0171, P0420) ezikhomba ukungasebenzi kakuhle kwenkqubo echaphazela ukukhutshwa kwezinto ezikhutshwayo.
    • Umzekelo: AP0420ikhowudi ibonisa ukungasebenzi kakuhle kwesiguquli.
  2. Usasazo lweDatha ephilayo:
    • Beka iliso kwidatha yesivamvo sexesha lokwenyani (umzekelo, isivamvo sombane weoksijini, ukucuthwa kwamafutha) ukuchonga izitenxo.
  3. Jonga "IiMonitors zokuLungela":
    • Iimvavanyo zokukhutshwa zifuna zonke iimonitha (umzekelo, i-EVAP, i-catalytic converter) ukuba "zilungile." Izikena ziqinisekisa ukuba iisistim zigqibile ukuzijonga.
  4. NONE
    • Ukuphonononga iimeko ezigciniweyo (umthwalo wenjini, i-RPM, iqondo lokushisa) ngexesha ikhowudi iqhutywe ukuphindaphinda kunye nokuxilonga imiba.
  5. Coca iiKhowudi kwaye uSete kwakhona iziHloli:
    • Emva kokulungiswa, setha ngokutsha inkqubo yokuqinisekisa izilungiso kwaye ulungiselele ukuphinda uyivavanye.

Iingcebiso zokugqibela

  • Tyala imali kwiphakathi kuluhlu lwe-OBD-II iskena(umz., iKiKin) yohlalutyo oluneenkcukacha lwekhowudi.
  • Ngeekhowudi ezintsonkothileyo (umzekelo, ukusilela kwe-catalytic converter), dibana nomkhandi oyingcali.
  • Ukugcinwa rhoqo (iiplagi zentlantsi, izihluzi zomoya) kuthintela imiba emininzi enxulumene nokukhutshwa kwezinto ezikhutshwayo.

Ngokusebenzisa amandla akho eskena se-OBD-II, unokuxilonga kwaye ulungise iingxaki ezikhutshwayo ngokufanelekileyo, uqinisekisa ukudlula okugudileyo kuhlolo lwakho olulandelayo!
