U0232 Ulahlekile Ukuxhumana Nemojuli Yokulawula Ukutholwa Kwezithiyo - Kwesobunxele

Idatha ye-OBD-II DTC

Ukuxhumana Okulahlekile Ngemojula Yokulawula Ukutholwa Kwezithiyo - Kwesobunxele

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Obstacle Sensing Control Module (ODCM-L) 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.

Imojula Yokulawula Ukutholwa Kwezithiyo - Kwesokunxele (ODCM-L) ngokuvamile itholakala ngemuva kwamaphaneli omnyango oseceleni kwesobunxele, insika yesokunxele ethi B, C, noma D. Ithola okokufaka okuvela ezinzwa ezihlukahlukene, ezinye zazo ezixhunywe kuyo ngokuqondile. , futhi eziningi zazo zithunyelwa ngohlelo lokuxhumana ibhasi lisuka kumojula yokulawula i-powertrain (PCM). Lokhu okokufaka kuvumela imojula ukuthi yazise umshayeli ngesithiyo esikulelo hlangothi lwemoto. Imojuli futhi ingazisa imojula yokulawula i-airbag ngalokhu kuvinjelwa ukuze ikwazi ukuthatha isinyathelo sokuqala.

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 ohlelweni lokuphepha olungasebenzi.

Izimpawu zekhodi ye-U0232 zingafaka:

• Isibani sesixwayiso se-Airbag sivuliwe noma siyakhanya
• Inkomba yokuthola izithiyo ivuliwe
• Izithiyo ezingatholakali / ezingatholakali njalo
• I-ODCM-L ayivuli noma 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 umhlabathi ku-ODCM-L
• 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-U0232 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0232, zama ukufinyelela ku-ODCM-L. Uma ukwazi ukufinyelela amakhodi asuka ku-ODCM-L, khona-ke ikhodi ethi U0232 iyikhodi yesikhashana noma yememori. Uma ungakwazi ukufinyelela i-ODCM-L, ikhodi U0232 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma inhlabathi kumojula yokulawula ukuthola izithiyo - kwesokunxele.

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

Uma ikhodi ibuya noma ukuxhumana nemodyuli kungakatholakali, thola izixhumanisi zokuxhumana zebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-ODCM-L, esivame ukutholakala ngemuva kwamapaneli omnyango ohlangothini lwesobunxele, ngakwesobunxele b, c noma d insika. ... Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-ODCM-L. 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-ODCM-L. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-ODCM-L inamandla futhi iphansi. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-ODCM-L. Xhuma ibhethri ngaphambi kokuqhubeka, ushiye i-ODCM-L inqanyuliwe. Xhuma intambo ebomvu ye-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye efakwe kusixhumi se-ODCM-L, 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 kungakenzeki, noma awukwazanga ukusetha kabusha i-DTC U0232, into kuphela ongayenza ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe, njengoba lokhu kuzobonisa ukwehluleka kwe-ODCM-L. . Iningi lalawa ma-ODCM-L kufanele ahlelwe noma alinganiswe ukuze kufakwe kahle imoto.
