U0203 Ukuxhumana okulahlekile ngemodyuli yokulawula umnyango E

Idatha ye-OBD-II DTC

Kulahleke Ukuxhumana Nemojuli Elawula Umnyango E

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Door Control Module E (DCM-E) namanye amamojula okulawula emotweni awaxhumani. Umjikelezo osetshenziswa kakhulu ekuxhumaneni waziwa ngokuthi i-Controller Area Bus communication, noma ibhasi le-CAN.

Amamojula axhumana nomunye ngenethiwekhi, njengenethiwekhi onayo ekhaya noma emsebenzini. Abakhiqizi bezimoto basebenzisa amasistimu amanethiwekhi amaningi. Kuze kube unyaka we-2004, izindlela zokuxhumana phakathi kwemodyuli ezivame kakhulu (ezingaphelelisi) kwakuyi-serial interface, noma i-SCI; I-SAE J1850 noma ibhasi le-PCI; kanye neChrysler Collision Detection, noma i-CCD. Uhlelo olujwayeleke kakhulu olusetshenziswe ngemuva kuka-2004 lwaziwa njenge-Controller Area Network ukuxhumana, noma umane ibhasi le-CAN (futhi elisetshenziswe kuze kube ngu-2004 engxenyeni encane yezimoto). Ngaphandle kwale bhasi le-CAN, amamojula wokulawula awakwazi ukuxhumana futhi ithuluzi lakho lokuskena lingathola noma lingatholi ulwazi oluvela emotweni, kuya ngokuthi isiphi isifunda esithintekile.

I-Door E Control Module (DCM-E) ivamise ukutholakala ngemuva kwe-flap eduze komnyango. Ingafakwa futhi ngaphakathi komnyango okukhulunywa ngawo. Ithola okokufaka okuvela kuzinzwa ezihlukahlukene, ezinye zazo ezixhunywe kuyo ngokuqondile, futhi eziningi zithunyelwa ngohlelo lokuxhumana lwebhasi lusuka kumojula yokulawula i-powertrain (PCM). Lokhu okokufaka kuvumela imojula ukuthi ilawule ukukhiya / ukuvulwa komnyango womshayeli/umgibeli. Uma ikhona, ingalawula nokusebenza kwamawindi kagesi. Emaveni amancane nakwamanye amaSUV, ikwazi ukusebenzisa izicabha ezishelelayo ezinamandla nezicabha zokuphakamisa amandla.

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

Ukuqina kwekhodi nezimpawu

Ukungathí sina kuleli cala akukaze kube bucayi, njengoba lokhu kuyithuluzi lokusiza amakhasimende futhi uma kwenzeka ukuphelelwa amandla okuphelele, kuhlale kunomsebenzi owenziwe ngesandla. Ukuntuleka kokusebenza kwe-DCM-E akuthinti nganoma iyiphi indlela ukusebenza kwemoto.

Izimpawu zekhodi ye-U0203 zingafaka:

Amawindi omshayeli / abagibeli abhajwe endaweni eyodwa / angahambi
Izikhiye zeminyango yomshayeli / umgibeli azikhiyiwe / azivuliwe
Isilayidi Samandla Esishelelayo / I-Power Tailgate Ayihambisi Amandla
I-DCM-E ayivuli / ayisebenzi

izizathu

Imvamisa isizathu sokufaka le khodi sithi:

Vula ku-CAN ibhasi + noma - isekethe
Mfushane kuya emhlabathini noma emhlabathini kunoma yisiphi isifunda sebhasi le-CAN
Awekho amandla noma phansi kumojuli ye-DCM-E
Akuvamile - imojula yokulawula inephutha

Izinqubo zokuxilonga nokulungisa

Indawo enhle ukuqala KONKE ukuxilongwa ngogesi ukuhlola i-Technical Service Bulletins (TSB) yemoto yakho. Inkinga obhekene nayo ingase yaziwe ngabanye emkhakheni. Ukulungiswa okwaziwayo kungenzeka kukhishwe ngumkhiqizi futhi kungakongela isikhathi nemali ngesikhathi sokuxilongwa.

Kucatshangwa ukuthi umfundi wekhodi uyatholakala kuwe njengamanje, njengoba kungenzeka ukuthi ukwazile ukufinyelela amakhodi kuze kube manje. Bona ukuthi akhona yini amanye ama-DTC ahlobene nokuxhumana kwebhasi noma ibhethri / ukuthungela. Uma kunjalo, kufanele uwahlolisise kuqala, njengoba i-misdiagnosis yaziwa ukuthi iyenzeka uma uthola ikhodi ye-U0203 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0203, zama ukufinyelela i-DCM-E. Uma ukwazi ukufinyelela amakhodi asuka ku-DCM-E, ikhodi ethi U0203 iphakathi noma iyikhodi yememori. Uma i-DCM-E ingafinyeleleki, ikhodi ethi U0203 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu iphutha lesifunda elinqamula amandla noma phansi kumojula yokulawula umnyango. E.

Hlola wonke amafusi anikezela nge-DCM-E kule moto. Hlola zonke izisekelo ze-DCM-E. Thola izindawo zokubambelela phansi emotweni futhi uqinisekise ukuthi izixhumo zihlanzekile futhi zivikelekile. Uma kunesidingo, zisuse, thatha ibhulashi elincane le-bristle ne-baking soda / isisombululo samanzi bese uhlanza ngayinye, kokubili isixhumi nendawo lapho ixhuma khona.

Uma kukhona ukulungiswa okwenziwe, sula ama-DTC kunoma imaphi amamojula asetha ikhodi kumemori futhi ubone ukuthi ungakwazi yini ukuxhumana nemojuli ye-DCM-E. Uma ukuxhumana ne-DCM-E kuyalulama, inkinga kungenzeka ukuthi iyinkinga ye-fuse/yokuxhumana.

Uma ikhodi ibuya noma ukuxhumana nemojula kungakaqiniseki, thola ukuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-DCM-E, esivamise ukuba ngemuva kwebhaphu eduze komnyango okukhulunywa ngawo. ingabuye ifakwe ngaphakathi komnyango okukhulunywa ngawo. Nqamula ikhebula lebhethri elinegethivu ngaphambi kokunqamula isixhumi ku-DCM-E. 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. 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 kuhlola okumbalwa kagesi ngaphambi kokuxhuma kabusha izixhumi ku-DCM-E. Uzodinga ukufinyelela ku-digital volt ohmmeter (DVOM). Qiniseka ukuthi i-DCM-E inamandla nendawo. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-DCM-E. Xhuma ibhethri ngaphambi kokuqhubeka ne-DCM-E isanqanyuliwe. Xhuma intambo ebomvu ukusuka ku-voltmeter ukuya kumthombo wamandla ngamunye ongu-B + (ibhethri) ongena kusixhumi se-DCM-E kanye nentambo emnyama esuka ku-voltmeter iye endaweni enhle (uma ungaqiniseki, isigxobo esinegethivu sebhethri sihlala sisebenza). Kufanele ubone ukufundwa kwe-voltage yebhethri. Qiniseka ukuthi unesizathu esihle. Xhuma umthofu obomvu osuka ku-voltmeter uye kwibhethri ephozithivu (B +) kanye nomthofu omnyama emhlabathini ngamunye. Nakulokhu, kufanele ubone i-voltage yebhethri isikhathi ngasinye lapho 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 ziphumelela futhi ukuxhumana kungakenzeki, noma uma awukwazanga ukusetha kabusha i-DTC U0203, into kuphela ongayenza ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe, njengoba lokhu kuzobonisa ukwehluleka kwe-DCM-E. . Iningi lalawa ma-DCM-E kufanele ahlelwe noma alinganiswe ukuze alingane kahle emotweni.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi ye-U0203?

Uma usadinga usizo nge-DTC U0203, 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.
