U0221 Ukuxhumana Okulahlekile Ngomnyango Wokushintsha Umnyango G

Idatha ye-OBD-II DTC

Kulahleke Ukuxhumana noMnyango Shintsha G

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi inkinobho yomnyango G (DS-G) namanye amamojula wokulawula emotweni axhumani. Izifunda ezijwayele ukusetshenziswa kakhulu kwezokuxhumana zaziwa ngokuthi yi-Controller Area Bus communication, noma nje 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.

Iswishi yomnyango G (DS-G) imvamisa itholakala ngaphakathi komnyango okukhulunywa ngawo. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo zixhunywe ngqo kuyo, futhi iningi lithunyelwa ngenqubo yokuxhumana ngamabhasi kusuka kumodyuli wokulawula i-powertrain module (PCM). Lokhu kokufaka kuvumela imodyuli yomnyango ukulawula ukukhiya / ukuvula umnyango womshayeli / umgibeli. Uma ikhona, ingalawula futhi ukusebenza kwamawindi kagesi. Kuma-minivans namanye ama-SUV, ikwazi ukusebenza ngezicabha ezihambisa ngamandla nezicabha zokuphakamisa amandla. Bheka incwajana yemoto yakho ukunquma ukuthi imuphi umnyango onegama elithi “G” esimweni sakho.

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 lokusizakala kwamakhasimende, futhi uma kwenzeka uphela amandla kagesi, kuhlale kukhona ukusebenza ngezandla. Ukushoda kokusebenza kweDS-G akuphazamisi nakancane ukusebenza kwemoto.

Izimpawu zekhodi ye-U0221 zingafaka:

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

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 umhlabathi module ye-DS-G
• 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-U0221 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0221, zama ukufinyelela i-DS-G. Uma ukwazi ukufinyelela amakhodi asuka ku-DS-G ikhodi ethi U0221 iyikhodi yesikhashana noma yememori. Uma i-DS-G ingafinyeleleki, khona-ke ikhodi ethi U0221 amanye amamojula asethiwe iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okunqamula amandla noma phansi kuswishi yomnyango g.

Bheka wonke amafiyuzi ahambisa imodyuli ye-DS-G kule moto. Bheka zonke izizathu ze-DS-G. 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 amakhodi ezinkinga zokuxilonga kunoma yimaphi amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana nemodyuli ye-DS-G. Uma ukuxhumana ne-DS-G kululama, inkinga kungenzeka ibe yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana nemodyuli kusahluleka, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-DS-G, esivame ukutholakala ngaphakathi komnyango okukhulunywa ngawo. Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-DS-G. 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 kuhlola okumbalwa kagesi ngaphambi kokuxhuma kabusha izixhumi ku-DS-G. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-DS-G inamandla futhi iphansi. Finyelela kumdwebo kagesi futhi unqume ukuthi amandla amakhulu nemithombo yaphansi ingena kuphi ku-DS-G. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-DS-G isavaliwe. Xhuma intambo ebomvu ye-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye efakwe kusixhumi se-DS-G, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, ukungabi nebhethri kusebenza njalo). 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 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 kungenakwenzeka, noma awukwazanga ukusetha kabusha i-DTC U0221, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-DS-G. . Iningi lalawa ma-DS-G kufanele ahlelwe noma alinganiswe ukuze alingane kahle emotweni.

Izingxoxo ezihlobene ze-DTC
