U0250 Ukuxhumana Okulahlekile NgeModyuli Yohlelo Lokuhlukaniswa Komthelela

Idatha ye-OBD-II DTC

Kulahlekile Ukuxhumana neModyuli Yohlelo Lokuhlukaniswa Komthelela

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Impact Classification System Module (ICSM) namanye amamojula wokulawula emotweni awahlangani. 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.

Imodyuli ye-Impact Classification System (ICSM) imvamisa itholakala ngemuva kwesikhungo sedeshibhodi. Ingafakwa futhi ngaphakathi kwekhonsoli yesikhungo. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo ezixhumeke ngqo kuyo, futhi iningi lidluliswa ngohlelo lokuxhumana ngamabhasi kusuka kumodyuli we-powertrain control module (PCM). Lokhu okufakwayo kuvumela imodyuli ukuthi inqume uhlobo lwethonya imoto eye yabhekana nalo nokuthi ama-airbags / ohlangothini amakhethini omoya angadinga ukusatshalaliswa ngasiphi isivinini.

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

Ukuqina kwekhodi nezimpawu

Ubukhulu kuleli cala bungaba noma bungabi bukhulu, kuya ngokuthi inkinga ikuphi. Umenzi angalungisa inkinga mathupha uma kwenzeka ukwehluleka kwebhasi.

Izimpawu zekhodi ye-U0250 zingafaka:

• Inkomba ye-Airbag ivuliwe
• Ilambu lokuxwayisa i-airbag yabagibeli livuliwe

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 we-ICSM
• 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-U0250 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0250, zama ukufinyelela i-ICSM. Uma ukwazi ukufinyelela amakhodi avela ku-ICSM khona-ke ikhodi ethi U0250 iyikhodi yesikhashana noma yememori. Uma i-ICSM ingafinyeleleki, khona-ke ikhodi ethi U0250 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi kumojula ye-Shock Classification System.

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

Uma ikhodi ibuya noma ukuxhumana nemodyuli kusahluleka, funa ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-ICSM, esivame ukutholakala ngemuva enkabeni yedeshibhodi. ingafakwa futhi ngaphakathi kwekhonsoli yesikhungo. Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-ICSM. 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 izixhumi emuva ku-ICSM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-ICSM inamandla kanye nomhlabathi. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nezizathu zingena kuphi ku-ICSM. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-ICSM lisavaliwe. Xhuma umthofu obomvu we-voltmeter ku-B+ ngayinye (i-voltage yebhethri) efakwe kusixhumi se-ICSM, kanye nomthofu omnyama we-voltmeter endaweni enhle (uma ungaqiniseki, i-negative yebhethri ihlala isebenza). 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 ziphumelela futhi nokuxhumana kungenzeki, noma awukwazanga ukusetha kabusha i-DTC U0250, into kuphela engenziwa ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe njengoba lokhu kuzobonisa ukwehluleka kwe-ICSM. Iningi lalawa ma-ICSM kufanele ahlelwe noma alinganiswe ukuze kufakwe kahle imoto.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi ye-U0250?

Uma usadinga usizo nge-DTC U0250, 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.
