1. Lalacewar abin da ke faruwa na firikwensin zafin jiki na abin sha:

① A cikin matsayi na ON, hasken wutan injin yana kunna kullun;

(2) ɗan ƙaramin hayaƙi mai baƙar fata lokacin da ake takawa a kan totur a hankali a cikin wurin, da kuma yawan hayaƙi mai yawa yayin saurin sauri;

③ Injin yana da ban sha'awa;

④ Lambobin kuskure: P01D6 (nau'in wutar lantarki na firikwensin abin sha yana da ƙasa da ƙananan iyaka) Sakamakon bincike: Siginar matsa lamba ba shi da kyau, kuma ECU ba zai iya karɓar daidaitattun bayanan ci ba, yana haifar da allurar man fetur mara kyau, don haka konewa bai isa ba, injin yana da ban sha'awa, kuma baƙar hayaki yana fitowa yayin da ake ƙara mai. Matsaloli a haɗin haɗin wayar hannu da gazawar firikwensin na iya haifar da wannan gazawar. Magani: Bincika firikwensin zafin jiki na matsi.

2, yanayin lalacewar firikwensin zafin ruwa:

① A cikin matsayi na ON, hasken wutan injin yana kunna kullun;

② Yanayin zafin ruwa a cikin kayan ON yana nuna matsakaicin ƙimar ZI na 120 ℃;

③ Injin yana da iyaka a cikin juzu'i da ban sha'awa;

④ Lambobin kuskure: P003D (matsayin wutar lantarki na firikwensin zafin ruwa yana ƙasa da ƙananan iyaka) Sakamakon bincike: Ma'aunin zafin jiki na ruwa ya kasa, kuma ECU yana amfani da madaidaicin darajar lokacin da ya gano cewa siginar fitarwa na firikwensin zafin ruwa ba shi da tabbas. , kuma ECU yana iyakance jujjuyawar injin don manufar kare injin. Magani: Bincika firikwensin zafin ruwa.

3. Lalacewar firikwensin matsa lamba mai:

① Bayan farawa, alamar man fetur yana kan kullun;

② Hasken kuskuren injin yana kunne koyaushe;

(3) Gudun rashin aiki, ƙimar matsa lamba mai yana nuna 0.99; ④ Lambar kuskure: P01CA (matsayin wutar lantarki na firikwensin mai ya fi girma fiye da babba) Sakamakon bincike: bincike na firikwensin mai ya lalace sosai, kuma ECU ya gano cewa ba a haɗa firikwensin mai ba, da kayan aiki. Ƙimar nuni ƙima ce ta maye gurbin ECU. Magani: Duba firikwensin matsa lamba mai.

4. Mummunan lamba na OBD soket tashoshi:

① A cikin matsayi na ON, wutar lantarki na kayan aikin bincike na al'ada ne, amma ba zai iya shiga ECU don karanta bayanan da suka dace ba;

② Babu lambar kuskure. Binciken sanadi: OBD soket ta ƙare, yana haifar da mummunan hulɗa, kuma kayan aikin bincike da ECU ba za su iya sadarwa ba. Magani: Duba tashar soket na OBD.

5. Lamarin gajeriyar kewayawa na kayan aikin waya na firikwensin NOx:

① Bayan farawa, hasken kuskuren OBD koyaushe yana kunne;

② Injin yana iyakance a cikin juzu'i da ban sha'awa;

③ Lambobin kuskure: P0050 (ƙasa NOx firikwensin CAN siginar lokacin liyafar liyafar) da P018C (lokacin shirye-shiryen firikwensin NOx na ƙasa). Binciken sanadi: Harshen na'urar firikwensin NOx ya ƙare, gajeriyar kewayawa da ƙasa, kuma firikwensin NOx ba zai iya aiki akai-akai ba, yana haifar da fitar da hayaki mai yawa, ƙayyadaddun juzu'in injin da ƙararrawar tsarin. Magani: Bincika kayan aikin waya na firikwensin NOx.
