Nnwale mgbapụta agaghị eme? Dezie koodu OBD-II 10 a na-ahụkarị tupu nyocha gị ọzọ

Ụgbọ ala ọgbara ọhụrụ na-adabere na sistemụ On-Board Diagnostics II (OBD-II) iji nyochaa arụmọrụ injin na ikuku. Mgbe ụgbọ ala gị daa n'ule emission, ọdụ ụgbọ mmiri nchọpụta OBD-II ga-abụ ngwaọrụ gị kacha mma maka ịchọpụta na idozi nsogbu. N'okpuru ebe a, anyị na-akọwa otú nyocha OBD-II si arụ ọrụ ma na-enye ihe ngwọta maka koodu nsogbu 10 na-emekarị nke nwere ike ịkpata ọdịda ikuku.

Kedu ka ndị nyocha OBD-II na-enyere aka ịchọpụta ihe ndị na-emepụta ihe

  1. Gụọ Koodu Nsogbu Nchọpụta (DTC):
    • Ihe nyocha OBD-II na-eweghachite koodu (dịka, P0171, P0420) nke na-akọwapụta nrụrụ sistemu akọwapụtara nke na-emetụta ikuku.
    • Ọmụmaatụ: AP0420koodu na-egosi emezighị emezi ihe ntụgharị catalytic.
  2. Ngụgharị data dị ndụ:
    • Nyochaa data ihe mmetụta ozugbo (dịka ọmụmaatụ, voltaji ihe mmetụta oxygen, trim mmanụ) iji chọpụta adịghị mma.
  3. Lelee "Nleba anya Njikere":
    • Nnwale ikuku na-achọ ka ndị nleba anya niile (dịka, EVAP, onye ntụgharị catalytic) ka ọ bụrụ “njikere.” Ndị nyocha na-egosi ma sistemụ emechala nyocha onwe ya.
  4. Data Frame kwụsịrị:
    • Nyochaa ọnọdụ echekwara (ibu engine, RPM, okpomọkụ) n'oge a kpalitere koodu iji megharịa na chọpụta nsogbu.
  5. Kpochapụ Koodu na Tọgharịa Monitors:
    • Mgbe emezichara, megharịa usoro ahụ iji nyochaa ndozi ma kwado maka nyochagharị.

Ndụmọdụ ikpeazụ

  • Tinye ego na anyocha nke etiti OBD-II(dịka ọmụmaatụ, iKiKin) maka nyocha koodu zuru ezu.
  • Maka koodu ndị dị mgbagwoju anya (dịka ọmụmaatụ, ọdịda ihe ntụgharị catalytic), kpọtụrụ onye na-arụ ọrụ ọkachamara.
  • Ndozi mgbe niile (mkpọku ọkụ, ihe nzacha ikuku) na-egbochi ọtụtụ nsogbu metụtara ikuku.

Site n'ịkwalite ikike nyocha OBD-II gị, ị nwere ike ịchọpụta ma dozie nsogbu ikuku nke ọma, na-ahụ na ị gafefe nke ọma na nyocha gị ọzọ!
