U0157 Kulahleke ukuxhumana nesikhungo solwazi B
Idatha ye-OBD-II DTC
Kulahleke ukuxhumana ne-Call Center B
Kusho ukuthini lokhu?
Le yikhodi yenkinga yokuxilongwa yohlelo lokuxhumana ejwayelekile esebenza kokuningi nokwenziwa kwezimoto.
Le khodi isho ukuthi i-Information Center "B" (IC-B) 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.
I-IC-B ivame ukutholakala ngemuva kwedeshibhodi, imvamisa iphakathi nendawo emotweni. Yamukela idatha yokufaka evela ezinzwa ezahlukahlukene, ezinye zazo zixhunywe kuyo ngqo, kanti ezinye zithunyelwa ngohlelo lokuxhumana ngamabhasi. Lokhu kokufaka kuvumela imodyuli ukuthi ikhombise imininingwane maphakathi ukuze ibukwe kalula.
Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomenzi, uhlobo lohlelo lokuxhumana, inani lezintambo, nemibala yezintambo ezisohlelweni lokuxhumana.
Ukuqina kwekhodi nezimpawu
Ubunzima kuleli cala buhlala bukhulu kakhulu ngenxa yezinkinga zokuphepha ezivela ku-IC-B ekwazi ukuphazamisa umbono womshayeli.
Izimpawu zekhodi yenjini engu-U0157 zingafaka:
- Info center Isikhungo se-no info / blank
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 isisekelo se-HUD module
- 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-U0157 ngaphambi kokuthi noma yimaphi amakhodi amakhulu ahlolwe ngokuphelele futhi enqatshelwe.
Uma ithuluzi lakho lokuskena lingafinyelela amakhodi ezinkinga futhi okuwukuphela kwekhodi oyithola kwamanye amamojula ngu-U0157, zama ukufinyelela ku-IC-B. Uma ukwazi ukufinyelela amakhodi asuka ku-IC-B, khona-ke ikhodi ethi U0157 iyikhodi yesikhashana noma yememori. Uma ungakwazi ukufinyelela ku-IC-B, ikhodi U0157 esethiwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.
Ukwehluleka okuvame kakhulu ukulahlekelwa amandla noma indawo ku-IC-B.
Bheka wonke amafiyuzi ahambisa imodyuli ye-IC-B kule moto. Bheka zonke izisekelo ze-IC-B. Thola izindawo zokumisa 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-DTCs kwimemori bese ubona ukuthi u-U0157 uyabuya noma ungaxhumana nemodyuli ye-IC-B. Uma kungekho khodi ebuyayo noma ukuxhumeka kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.
Uma ikhodi ibuya, funa ukuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-IC-B, esivame ukutholakala ngemuva kwedeshibhodi. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi kwimodyuli ye-IC-B. 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.
Ngaphambi kokuxhuma kabusha izixhumi ku-IC-B, yenza lokhu kuhlola okumbalwa kwamandla kagesi. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-IC-B inamandla nendawo. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-IC-B. Phinda uxhume ibhethri ngaphambi kokuqhubeka ne-IC-B isavaliwe. Xhuma umthofu obomvu we-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye efakwe kusixhumi se-IC-B, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, i-negative yebhethri ihlala isebenza). 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 uma ungakwazi ukusetha kabusha i-DTC U0157, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-IC-B. . Iningi lalawa ma-IC-B 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 yakho ye-u0157?
Uma usadinga usizo nge-DTC U0157, 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.
