Idatha ye-OBD-II DTC

Ukuxhumana Okulahlekile Nge-Exhaust Gas Sensor Module

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Exhaust Gas Sensor Module (EGSM) 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-Exhaust Gas Sensor Module (EGSM) ivamise ukuba ngaphansi kwe-hood, kungaba ku-fender noma ku-bulkhead. 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 yazise i-PCM ngokuqukethwe kwe-oxygen ngaphakathi kwegesi yokukhipha ukuze kuqinisekiswe ukusha okuphelele nokunciphisa ukukhishwa kwe-exhaust.

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

Ukuqina kwekhodi nezimpawu

Ubunzima kuleli cala abunabungozi ngoba i-PCM inesu lokwenza isipele uma kwenzeka ilahlekelwa ukuxhumana ne-EGSM.

Izimpawu zekhodi ye-U011A zingafaka:

I-EGSM 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-EGSM
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-U011A ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U011A, zama ukufinyelela ku-EGSM. Uma ukwazi ukuthola amakhodi asuka ku-EGSM ikhodi ethi U011A iyikhodi yesikhashana noma yememori. Uma i-EGSM ingafinyeleleki, ikhodi U011A esethwe ngamanye amamojuli iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okunqamula amandla noma phansi kumojula yenzwa yegesi ephumayo.

Hlola wonke amafusi anikezela nge-EGSM kule moto. Hlola zonke izizathu ze-EGSM. 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 i-DTCs kunoma yimaphi amamojula asetha ikhodi enkumbulweni futhi ubone ukuthi ungakwazi yini ukuxhumana ne-EGSM. Uma ukuxhumana ne-EGSM kuyalulama, inkinga kungenzeka ibe yinkinga ye-fuse/yokuxhumana.

Uma ikhodi ibuya noma ukuxhumana nemojula kungakatholakali, thola ukuxhumana kwebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-EGSM, esivame ukutholakala ngaphansi kwe-hood kuma-fenders noma ku-bulkhead. Nqamula ikhebula lebhethri elinegethivu ngaphambi kokunqamula isixhumi ku-EGSM. 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 izixhumi emuva ku-EGSM. Uzodinga ukufinyelela ku-digital volt ohmmeter (DVOM). Qiniseka ukuthi i-EGSM inikwe amandla futhi isekelwe. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-EGSM. Phinda uxhume ibhethri ngaphambi kokuqhubeka ne-EGSM isavaliwe. Xhuma intambo ebomvu ye-voltmeter yakho kumthombo wamandla ngamunye ongu-B + (ibhethri) ongena kusixhumi se-EGSM, kanye nentambo emnyama ye-voltmeter yakho endaweni enhle (uma ungaqiniseki, isigxobo esinegethivu sebhethri sihlala sisebenza). Kufanele ubone 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 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 awukwazanga ukusetha kabusha i-DTC U011A, okuwukuphela kwento engenziwa ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe njengoba lokhu kuzobonisa ukwehluleka kwe-EGSM. Iningi lalawa ma-EGSM kumele ahlelwe noma alinganiswe ukuze akwazi ukufaka kahle imoto.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi U011A?

Uma usadinga usizo nge-DTC U011A, thumela umbuzo wakho 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.
