U0147 Ukuxhumana okulahlekile ngesango B

Idatha ye-OBD-II DTC

Kulahleke Ukuxhumana ne-Gateway "B"

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilongwa yohlelo lokuxhumana ejwayelekile esebenza kokuningi nokwenziwa kwezimoto. Le khodi isho ukuthi imojula yesango "B" namanye amamojula okulawula emotweni awaxhumani.

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 yesango inesibopho sokudlulisa imininingwane isuka kunethiwekhi eyodwa yebhasi ye-CAN iye kwamanye amamojula kwenye inethiwekhi yebhasi ye-CAN. Ithuluzi lakho lokuskena livame ukuxhuma kule module yesango ukufinyelela womabili amanethiwekhi webhasi we-CAN ngasikhathi sinye ukusheshisa izikhathi zokufinyelela.

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

izimpawu

Izimpawu zekhodi yenjini engu-U0147 zingafaka:

• Ilambu Lenkomba Yokungasebenzi (MIL) likhanyisiwe
• Imoto ingaqala noma ingavumi
• Isibonisi se-ABS sivuliwe
• Isikhombi se-TRAC sivuliwe (kuya ngomkhiqizi)
• Isibonisi se-ESP / ESC sivuliwe (kuya ngomkhiqizi)

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
• Amandla noma i-ground break kumojuli ye-GATEWAY "B" - ngokuvamile
• 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.

Uma ithuluzi lakho lokuskena lingafinyelela amakhodi enkathazo futhi okuwukuphela kwekhodi oyikhipha kwamanye amamojula ngu-U0147, zama ukufinyelela imojula ye-GATEWAY. Uma ukwazi ukufinyelela amakhodi kumojula ye-GATEWAY, khona-ke ikhodi ethi U0147 iphakathi noma iyikhodi yememori. Uma amakhodi emojula ye-GATEWAY engafinyeleleki, khona-ke ikhodi ethi U0147 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukulahlekelwa amandla noma isisekelo semojuli.

Bheka wonke amafuyuzi ahambisa imodyuli ye-GATEWAY kule moto. Bheka zonke izizathu zemodyuli yeGATEWAY. 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 kwimemori bese ubona ukuthi u-U0147 uyabuya noma ungaxhumana nemodyuli yeGATEWAY. Uma kungekho khodi ebuyiswayo noma ukuxhumana kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.

Uma ikhodi ibuya, funa ukuxhumana kwebhasi le-CAN C emotweni yakho ethize, ikakhulukazi isixhumi semodyuli ye-GATEWAY. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi kwimodyuli yokulawula ye-GATEWAY. 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 igrisi kagesi lapho amatheminali ethinta khona.

Yenza lokhu kuhlolwa kwamandla kagesi ambalwa ngaphambi kokuxhuma izixhumi ku-GATEWAY. Uzodinga ukufinyelela kwimitha ye-digital volt ohm (DVOM). Qiniseka ukuthi unamandla nomhlabathi kwimodyuli yeGATEWAY. Finyelela kumdwebo wiring bese unquma ukuthi amandla amakhulu nempahla yomhlaba ingena kuphi kumodyuli we-GATEWAY. Xhuma ibhethri ngaphambi kokuqhubeka nokunqanyulwa kwe-GATEWAY. Xhuma ucingo olubomvu lwe-voltmeter yakho kumthombo ngamunye wamandla we-B + (amandla webhethri) oya kusixhumi kwimodyuli ye-GATEWAY, nocingo olumnyama lwe-voltmeter yakho emhlabathini omuhle (uma ungaqiniseki, isigxobo esibi sebhethri sisebenza njalo) . Ungabona ukufundwa kwamandla kagesi webhethri. Qiniseka ukuthi unesizathu esihle. Xhuma ucingo olubomvu kusuka ku-voltmeter kuye ku-battery positive (B +) kanye nocingo olumnyama emhlabathini ngamunye. Nakulokhu futhi, kufanele ubone i-voltage yebhethri njalo lapho uyixhuma. Uma kungenjalo, xazulula inkinga yesekethe yamandla noma yomhlabathi.

Bese uhlola izifunda ezimbili zokuxhumana. Thola i-CAN C+ (noma i-HSCAN+) kanye ne-CAN C- (noma i-HSCAN - isekethe). Ngentambo emnyama ye-voltmeter exhunywe endaweni ekahle, xhuma intambo ebomvu ku-CAN C+. Uma ukhiye uvuliwe futhi injini icishiwe, kufanele ubone cishe ama-volts angu-2.6 anokuguquguquka okuncane. Bese uxhuma intambo ebomvu ye-voltmeter kusekethe ye-CAN C-. Kufanele ubone cishe ama-volts angu-2.4 ngokuguquguquka okuncane. Abanye abakhiqizi bakhombisa i-CAN C- cishe i-5V kanye nokhiye ozungezayo lapho injini icishiwe. Hlola imininingwane yomkhiqizi wakho.

Bese ubheka ezinye 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 ziphumelela futhi nokuxhumana kungenzeki, noma awukwazanga ukusetha kabusha i-DTC U0147, okuwukuphela kwento engenziwa ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe njengoba lokhu kuzobonisa imojuli ye-GATEWAY enephutha. Iningi lala mamojula we-GATEWAY kufanele ahlelwe noma alinganiswe ukuze imoto ifakwe kahle.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi yakho ye-u0147?

Uma usadinga usizo nge-DTC U0147, 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.
