Isifunda senzwa yesivinini sokuphuma - ukulahlekelwa kwesignali yesihloko

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Ezijwayelekile Yokuxilongwa Kwe-Powertrain (DTC) isetshenziswa kakhulu ezimotweni eziningi ze-OBD-II. Lokhu kungafaka kepha akukhawulelwe ku-Chevrolet, Ford, Toyota, Dodge, Honda, njll.

Lapho imoto yakho igcine ikhodi engu-P077A, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole ukulahleka kwesiginali esiqondayo kusuka kunzwa yejubane lokukhipha.

Izinzwa zejubane lokukhipha zivame ukuba ngogesi. Basebenzisa uhlobo oluthile lwendandatho yokusabela enamazinyo noma igiya elinamathele unomphela kushaft yokukhipha yokudlulisa. Njengoba i-shaft ekhishwayo izungeza, iringi ophendulayo iyajikeleza. Amazinyo aqhakazile endandatho yesiphenduli aqedela isekethe yesisindo sesivinini sokukhipha njengoba edlula eduze kwenzwa emile kagesi. Lapho ophendulayo edlulisa ithiphu ye-electromagnetic yenzwa, ama-notches phakathi kwamazinyo endandatho ye-reactor enza ukuyeka ukusebenza kusifunda senzwa. Le nhlanganisela yokunqanyulwa kokuphazanyiswa kanye nokuphazamiseka itholwa yi-PCM (nabanye abalawuli) njengamaphethini e-waveform amele isilinganiso sokukhishwa kwe-baud.

Inzwa is screwed ngqo endlini yokudlulisela noma ibanjelwe endaweni ngebhawudi. I-O-ring isetshenziselwa ukuvimbela uketshezi ekuvuzeni ngaphandle kwenzalo.

I-PCM iqhathanisa isivinini sokufaka nesokukhipha sokudlulisa ukuthola ukuthi ukudluliswa kuhamba ngokufanele yini futhi kusebenza kahle.

Uma ikhodi ye-P077A igcinwe, i-PCM ithole isignali yamandla wokufaka kusuka kunzwa yejubane lokukhipha ekhombisa ukuthi iringi yesiphenduli ayihambi. Lapho isignali ye-voltage sensor sensor ingashintshi, i-PCM icabanga ukuthi indandatho yesiphenduli iyekile ngokungazelelwe ukuhamba. I-PCM ithola okokufaka isivinini semoto kanye nokufakwa kwejubane lesondo ngaphezu kwedatha yenzwa yejubane. Ngokuqhathanisa lezi zimpawu, i-PCM inganquma ukuthi indandatho yesiphenduli ihamba ngokwanele (ngokusho kwesiginali esivela kunzwa yejubane lokukhipha). Isiginali yesisindo senzwa esheshayo ingabangelwa inkinga kagesi noma inkinga yemishini.

Nasi isibonelo senzwa yesivinini sokudlulisa:

Buyini ubunzima bale DTC?

Izimo ezinomthelela ekuphikeleni kwekhodi ye-P077A zingahle noma zingaholela ekwehlulekeni kokudluliswa kwenhlekelele futhi kufanele zilungiswe ngokushesha.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenjini engu-P077A zingafaka:

• Ukusebenza okungapheli kwe-speedometer / odometer
• Amaphethini wokushintsha amagiya angajwayelekile
• Ukudluliswa kokuhanjiswa noma ukubambezeleka kokubandakanya
• Ukwenza kusebenze / ukwenziwa kungasebenzi kokulawulwa kwe-traction (uma kusebenza)
• Amanye amakhodi wokudlulisa kanye / noma i-ABS angagcinwa

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Inzwa yejubane yokukhipha enephutha
• Imfucumfucu yensimbi kunzwa yesivinini sokukhipha
• Isifunda esivulekile noma esifushane kumasekethe noma izixhumi (ikakhulukazi eduze kwenzwa yejubane lokukhipha)
• Indandatho yesiphenduli elimele noma egqokile
• Ukwehluleka kokudluliswa kwemishini

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P077A?

Imvamisa ngithanda ukuqala ukuxilonga i-P077A ngokuhlolwa okubonakalayo kwe-wiring system kanye nezixhumi. Ngingasusa inzwa yejubane lokukhipha futhi ngisuse imfucumfucu yensimbi ethe xaxa kuthiphu kazibuthe. Qaphela lapho ukhipha inzwa njengoba uketshezi oludlulisayo lokushisa lungavuza ngaphandle kwenzwa. Lungisa isekethe evulekile noma emfushane kumasekethe nezixhumi uma kudingeka.

Ngemuva kokukhipha inzwa ukuze ihlolwe, hlola iringi yokusabela. Uma i-reactor ring yonakele, iqhekeziwe, noma uma kukhona amazinyo angekho (noma agugile), kungenzeka ukuthi uthole inkinga yakho.

Hlola uketshezi lokudlulisa oluzenzekelayo uma kuvela ezinye izimpawu ezihlobene nokudluliswa. Uketshezi kufanele luvele luhlanzeke kancane futhi lunganuki kushile. Uma izinga loketshezi lokuhambisa lingaphansi kwelitha elilodwa, gcwalisa uketshezi olufanele bese uhlola ukuvuza. Ukuhanjiswa kufanele kugcwaliswe uketshezi olulungile futhi lube sesimweni esihle somshini ngaphambi kokutholakala.

Ngizodinga isithwebuli sokuxilonga esine-oscilloscope esakhelwe ngaphakathi, i-digital volt / ohmmeter (i-DVOM) nomthombo othembekile wolwazi lwemoto ukuthola ikhodi ye-P077A.

Ngithanda ukuxhuma isithwebuli esikhumulweni sokuxilonga imoto bese ngithola wonke ama-DTC agciniwe futhi ngifrize idatha yozimele. Ngingalubhala phansi lolu lwazi ngaphambi kokususa noma yimaphi amakhodi, ngoba angabonakala elusizo njengoba ukuxilongwa kwami ​​kuqhubeka.

Thola ama-Bulletins (TSB) afanele usebenzisa i-information information yemoto yakho. Ukuthola i-TSB efana nezimpawu namakhodi agciniwe (wemoto okukhulunywa ngayo) kungahle kuholele ekutholeni ukuxilongwa okusheshayo nokunembile.

Sebenzisa ukusakazwa kwedatha yesithwebuli ukuqapha isivinini sokukhipha ngesikhathi sokushayela kokuhlolwa kwemoto. Ukunciphisa ukusakazwa kwedatha ukubonisa kuphela izinkambu ezifanele kuzokhulisa ijubane nokunemba kokulethwa kwedatha. Izimpawu ezingahambelani noma ezingahambelani ezivela kuzinzwa zokufaka noma zokuphuma kwejubane zingadala izinkinga nge-wiring, isixhumi sikagesi, noma inzwa.

Nqamula inzwa yesivinini sokukhipha bese usebenzisa i-DVOM ukuhlola ukumelana. Umthombo wakho wolwazi lwemoto kufanele ubandakanye imidwebo yezintambo, izinhlobo zezixhumi, izipikisi zokuxhuma, kanye nezinqubo / imininingwane yokunconywa yomkhiqizi. Uma inzwa yesivinini sokukhipha ingaphandle kokucaciswa, kufanele ibhekwe njengengalungile.

Idatha yesikhathi sangempela kusuka kunzwa yejubane lokukhipha ingatholakala kusetshenziswa i-oscilloscope. Hlola ucingo lwesiginali yesivinini sokukhipha kanye nentambo yensimbi yomhlabathi. Ungahle udinge ukujija noma ukuphakamisa imoto ukuqedela lolu hlobo lokuhlola. Ngemuva kokuthi amasondo okushayela asuke phansi ngokuphepha futhi imoto iboshelwe ngokuphepha, qala ukudluliswa ngokubheka ishadi le-waveform kwi-oscilloscope. Ufuna ama-glitches noma ukungahambisani ngendlela yamagagasi eyenziwe yisiginali yenzwa yokukhipha isivinini.

• Nqamula izixhumi kwizilawuli ezixhunyiwe lapho wenza ukuhlolwa kwesekethe nokuqhubeka kokuqhubeka ne-DVOM. Ukwehluleka ukwenza kanjalo kungalimaza isilawuli.

Udinga usizo olwengeziwe ngekhodi le-P077A?

Uma usadinga usizo maqondana ne-DTC P077A, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
