U0139 Ukuxhumana Okulahlekile NgeModyuli Yokulawula Ukumiswa

Idatha ye-OBD-II DTC

Kulahleke Ukuxhumana Nemojula Yokulawula Ukumiswa "B"

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilongwa yohlelo lokuxhumana ejwayelekile esebenza kokuningi nokwenziwa kwezimoto.

Le khodi isho ukuthi iSuspension Control Module B (SCM-B) namanye amamojula okulawula emotweni awaxhumani. Umjikelezo osetshenziswa kakhulu ekuxhumaneni waziwa ngokuthi i-Controller Area Bus communication, noma 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-SCM-B yamukela idatha yokufaka evela kuzinzwa ezihlukahlukene, ezinye zazo ezixhunywe kuyo ngokuqondile, futhi ezinye zazo ezidluliselwa ngohlelo lokuxhumana lwebhasi. Lokhu okokufaka kuvumela imojula ukuthi ilawule kokubili ubude bemoto kanye nokushaqeka/ukusebenza kwe-strut, kuye ngohlelo lomkhiqizi. Kwezinye izimoto, umshayeli angakhetha uhambo oluthambile, oluqinile noma olune-sporty kuye ngokulawulwa ngesandla noma, kwezinye izimo, ngokucindezela nje ibhuleki noma i-accelerator pedal. Uma amabhuleki eqiniswe ngokuqinile, noma uma umshayeli esheshisa ngokushesha, isistimu ingakhetha ukushayela kanzima esikhundleni sokusetha okuthambile okuzenzakalelayo kwangaphambilini.

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

Ubunzima nezimpawu

Ubunzima kuleli cala buncike ohlelweni. Imvamisa, lapho imoto ifinyelela imvume ephansi, isistimu iyavalwa. Inqobo nje uma ukwehluleka kwenzeka ngalesi sikhathi, akufanele kube nemiphumela emibi ekuphepheni kwemoto/isistimu/ukushayela. Uma ukwehluleka kungenxa yokwehluleka kwe-compressor / ventilation / shock / strut, lokhu kungaba yimbangela yokukhathazeka njengoba udaba lokuphepha lungase luvele noma nini uma kungenjalo. Ukwengeza, ukuphepha kubalulekile lapho uhlinzeka lezi zinhlelo. NJALO ubhekise kulwazi lwesevisi ngaphambi kokuhlakaza / ukuxilonga lezi zinhlelo.

Izimpawu zekhodi yenjini engu-U0139 zingafaka:

• Isibani sesixwayiso sokumiswa sivuliwe
• Ukususwa komhlaba okungeyona imoto
• Ukuduma kuzwakala umzuzu ngemuva kokucindezela ukhiye wokuqala.

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 alahlekile noma phansi kumojuli ye-SCM-B yikhona okuvame kakhulu
• 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-U0139, zama ukufinyelela "B" imojuli yokulawula ukumiswa. Uma ukwazi ukufinyelela amakhodi ku-SCM-B, ikhodi ye-U0139 kungaba yikhodi yesikhashana noma ikhodi yememori. Uma amakhodi emojula ye-SCM-B engafinyeleleki, ikhodi ethi U0139 esethwe ngamanye amamojuli iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu ukulahlekelwa amandla noma umhlabathi kumojula ye-SCM-B.

Bheka wonke amafuyuzi ahambisa i-SCM-B kule moto. Bheka zonke izizathu ze-SCM-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 i-DTCs enkumbulweni futhi ubone ukuthi i-U0139 iyabuya yini noma ungathintana ne-SCM-B. Uma kungekho khodi ebuyisiwe noma ukuxhumana kubuyiswe, inkinga kungenzeka ukuthi iyinkinga ye-fuse / yokuxhuma.

Uma ikhodi ibuya, bheka ukuxhumana kwebhasi le-CAN C emotweni yakho ethile, ikakhulukazi isixhumi se-SCM-B. Nqamula intambo yebhethri enegethivu ngaphambi kokunqamula isixhumi ku-SCM-B. Uma usutholakele, bheka ngokubukeka izixhumi nezintambo. Bheka imihuzuko, ama-scuffs, izintambo eziveziwe, izimpawu zokusha, noma ipulasitiki encibilikisiwe. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bheka ukuthi zibukeka zishile yini noma zine-tint eluhlaza ekhombisa ukugqwala. Uma udinga ukuhlanza amatheminali, sebenzisa isicoci esithinta ugesi kanye nebhulashi le-plastic bristle. Vumela ukuba zome futhi usebenzise amafutha kagesi lapho amatheminali athinta khona.

Yenza lokhu kuhlola okumbalwa kagesi ngaphambi kokuxhuma izixhumi emuva ku-SCM-B. Uzodinga ukufinyelela ku-digital volt ohmmeter (DVOM). Qiniseka ukuthi i-SCM-B inamandla futhi iphansi. Finyelela kumdwebo wezintambo bese unquma ukuthi amandla ayisisekelo nezinto ezisetshenziswayo zaphansi zingena kuphi ku-SCM-B. Xhuma ibhethri ngaphambi kokuqhubeka ne-SCM-B isanqanyuliwe. Xhuma intambo ebomvu ye-voltmeter yakho kumthombo wamandla ngamunye ongu-B + (ibhethri) ongena kusixhumi se-SCM-B, kanye nentambo emnyama ye-voltmeter yakho endaweni enhle (uma ungaqiniseki, isigxobo esinegethivu sebhethri sihlala sisebenza). Ungabona ukufundwa kwe-voltage yebhethri. Qiniseka ukuthi unesizathu esihle. Xhuma intambo ebomvu ukusuka ku-voltmeter iye kubhethri positive (B +) kanye nentambo emnyama emhlabathini ngamunye. Nakulokhu, kufanele ubone i-voltage yebhethri njalo uma uyixhuma. Uma kungenjalo, xazulula inkinga yamandla noma isekethe yaphansi.

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.

Uma zonke izivivinyo zidlula futhi ukuxhumana kungakenzeki, noma awukwazanga ukusula ikhodi yenkinga ye-U0139, into kuphela ongayenza ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe njengoba lokhu kuzobonisa ukwehluleka kwe-SCM-B. imojula. Iningi lala mamojula e-SCM-B adinga ukuhlelwa noma ukulinganiswa kwemoto ukuze afakwe ngendlela efanele.

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

Udinga usizo olwengeziwe ngekhodi yakho ye-u0139?

Uma usadinga usizo nge-DTC U0139, 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.
