Ukuxhumana Okulahlekile NgeModyuli Yokulawula Isifudumezi Esisizayo

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilongwa yohlelo lokuxhumana ejwayelekile esebenza kokuningi nokwenziwa kwezimoto ze-OBD-II.

Le khodi isho ukuthi imodyuli yokulawula i-heater asizayo (i-AHCM) namanye amamojula wokulawula emotweni axhumani. Izifunda ezijwayele ukusetshenziswa kakhulu kwezokuxhumana zaziwa ngokuthi yi-Controller Area Bus communication, noma nje ibhasi le-CAN.

Ngaphandle kwaleli bhasi le-CAN, amamojula wokulawula awakwazi ukuxhumana futhi ithuluzi lakho lokuskena lingahle lingalutholi ulwazi oluvela emotweni, kuya ngokuthi isiphi isifunda esibandakanyekayo.

Imodyuli yokulawula i-heater esizayo ivame ukutholakala ngemuva kwedeshibhodi noma endaweni ye-console yendawo yemoto. Ithola imininingwane yokufaka evela ezinzwa ezahlukahlukene, ezinye zazo zixhunywe kuyo ngqo, iningi lazo lidluliselwa ngohlelo lokuxhumana ngamabhasi. Lokhu kokufaka kuvumela imodyuli ukuthi ilawule izinga lokushisa langaphakathi.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomenzi, uhlobo lohlelo lokuxhumana, inani lezintambo, nemibala yezintambo ezisohlelweni lokuxhumana.

Ukuqina kwekhodi nezimpawu

Ubulukhuni kuleli cala abukaze bube bucayi, ngoba lokhu kuyithuluzi lokusiza amakhasimende. Ukuntuleka kokusebenza kwe-AHCM akuphazamisi nakancane ukusebenza kwemoto.

Izimpawu zekhodi ye-U0166 zingafaka:

• Azikho izinguquko zokushisa kusuka ohlelweni lwe-heater olusizayo
• Uhlelo olwengeziwe lwe-heater alusebenzi / alukho impendulo

izizathu

Imvamisa isizathu sokufaka le khodi sithi:

• Vula kusifunda se-CAN +
• Vula ebhasini le-CAN - isekethe kagesi
• Isifunda esifushane sokufaka amandla kunoma yisiphi isifunda sebhasi le-CAN
• Mfushane kuya phansi kunoma yisiphi isifunda sebhasi le-CAN
• Awekho amandla noma umhlabathi ku-AHCM
• Akuvamile - imojula yokulawula inephutha

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Okokuqala, funa amanye ama-DTC. Uma okunye kwalokhu ukuxhumana kwebhasi noma ibhethri / ukuthungela okuhlobene, kuxilonge kuqala. I-Misdiagnosis iyaziwa ukuthi kungenzeka uma uthola ikhodi ye-U0166 ngaphambi kokuthi noma yimaphi amakhodi amakhulu ahlolwe ngokuphelele futhi enqatshelwe.

Uma ithuluzi lakho lokuskena lingafinyelela amakhodi ezinkinga futhi okuwukuphela kwekhodi oyithola kwamanye amamojula ngu-U0166, zama ukufinyelela i-Auxiliary Heater Control Module (AHCM). Uma ukwazi ukufinyelela amakhodi asuka ku-AHCM khona-ke ikhodi ethi U0166 iyikhodi yesikhashana noma yememori. Uma i-AHCM ingafinyeleleki, ikhodi ethi U0166 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukungasebenzi kahle okuvame kakhulu ukulahlekelwa amandla noma ukugxilwa kwemojuli yokulawula i-heater eyisizayo.

Bheka wonke amafuyuzi ahambisa i-AHCM kule moto. Bheka zonke izizathu ze-AHCM. Thola amaphuzu okunamathisela phansi emotweni bese uqinisekisa ukuthi lokhu kuxhumana kuhlanzekile futhi kuphephile. Uma kunesidingo, zisuse, thatha ibhulashi elincane le-wire bristle nesisombululo sesoda / samanzi bese uhlanza ngasinye, kokubili isixhumi nendawo lapho sixhuma khona.

Uma kukhona ukulungiswa okwenziwe, sula ama-DTC ememori bese ubona ukuthi u-U0166 uyabuya noma ungaxhumana ne-AHCM. Uma kungekho khodi ebuyiswayo noma ukuxhumana kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.

Uma ikhodi ibuya, funa ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-AHCM, esivame ukutholakala ngemuva kwedeshibhodi noma endaweni yekhonsoli yesikhungo semoto. Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-AHCM. Uma usutholakele, hlola ngokubonakalayo izixhumi nezintambo. Bheka imihuzuko, izikhafu, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe.

Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bona ukuthi zibukeka zishisiwe noma zinombala oluhlaza okhombisa ukugqwala. Uma udinga ukuhlanza ama-terminals, sebenzisa i-electric contact cleaner kanye ne-plastic bristle brush. Vumela ukomisa nokufaka i-dielectric silicone grease lapho kuthinta amatheminali.

Yenza lokhu kuhlola okumbalwa kagesi ngaphambi kokuxhuma izixhumi emuva ku-AHCM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-AHCM inamandla kanye nomhlabathi. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-AHCM. Xhuma ibhethri ngaphambi kokuqhubeka ne-AHCM isanqanyuliwe. Xhuma intambo ebomvu ye-voltmeter yakho ku-B+ ngayinye (i-voltage yebhethri) engena kusixhumi se-AHCM, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, ibhethri elinegethivu lihlala lisebenza). Kufanele ubone ukufundwa kwe-voltage yebhethri. Qiniseka ukuthi unesizathu esihle. Xhuma umthofu obomvu we-voltmeter kuphozithivu yebhethri (B+) kanye nomthofu omnyama kusekethe ngayinye yaphansi. Nakulokhu futhi, kufanele ubone i-voltage yebhethri njalo uma uxhuma. Uma kungenjalo, lungisa amandla noma isekethe yaphansi.

Bese uhlola izifunda ezimbili zokuxhumana. Thola i-CAN B+ (noma isekethe ye-MSCAN +) kanye ne-CAN B- (noma isekethe ye-MSCAN). Ngentambo emnyama ye-voltmeter exhunywe endaweni ekahle, xhuma intambo ebomvu ku-CAN B+. Uma ukhiye uvuliwe futhi injini icishiwe, kufanele ubone i-voltage engaba ngu-0.5 volts enokuguquguquka okuncane. Bese uxhuma umthofu obomvu we-voltmeter kusekethe ye-CAN B. Kufanele ubone cishe ama-volts angu-4.4 ngokuguquguquka okuncane.

Uma zonke izivivinyo zidlula futhi ukuxhumana kungenakwenzeka, noma awukwazanga ukusetha kabusha i-DTC U0166, into kuphela engenziwa ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-AHCM. Iningi lalawa ma-AHCM kufanele ahlelwe noma alinganiswe ukuze kufakwe kahle imoto.

Izingxoxo ezihlobene ze-DTC

• Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.

Udinga usizo olwengeziwe ngekhodi ye-U0166?

Uma usadinga usizo nge-DTC U0166, 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.
