U0215 Ukuxhumana Okulahlekile Ngokushintshwa Komnyango A

U0215 Ukuxhumana Okulahlekile Ngokushintshwa Komnyango A

Idatha ye-OBD-II DTC

Kulahleke ukuxhumana neswishi yomnyango A

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Door Switch A (DS-A) namanye amamojula okulawula emotweni awaxhumani. Isekhethi esetshenziswa kakhulu ukuxhumana yaziwa ngokuthi i-Controller Area Network Bus communication, noma ngaphezulu ngokubeka 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.

I-Door switch A (DS-A) ngokuvamile itholakala ngaphakathi komnyango okukhulunywa ngawo. Ithola okokufaka okuvela ezinzwa ezihlukahlukene, ezinye zazo ezixhunywe kuyo ngokuqondile, futhi eziningi zazo zidluliselwa ngohlelo lokuxhumana lwebhasi olusuka kumojula yokulawula i-powertrain (PCM). Lokhu okokufaka kuvumela imojula yesicabha ukuthi ilawule ukukhiya/ukuvulwa komnyango womshayeli/umgibeli. Uma ikhona, ingakwazi futhi ukuqapha ukusebenza kwezilawuli zewindi. Emaveni amancane nakwamanye amaSUV, ingakwazi ukulawula ukusebenza kwezicabha ezishelelayo namasango okuphakamisa amandla. Bheka imanuwali eqondene nemoto yakho ukuze uthole ukuthi yimuphi umnyango oqokwe ngokuthi "A" kuhlelo lwakho lokusebenza oluthile.

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

Ukuqina kwekhodi nezimpawu

Ubunzima kuleli cala abusoze bubucayi njengoba buwumshini wokusiza amakhasimende futhi uma kwenzeka ugesi wehluleka ngokuphelele kuhlale kunomsebenzi owenziwe ngesandla. Ukwehluleka ukusebenzisa i-DS-A akuthinti nangayiphi indlela ukusebenza kwemoto.

Izimpawu zekhodi ye-U0215 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 phansi kumojuli ye-DS-A
• 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-U0215 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0215, zama ukufinyelela i-DS-A. Uma ukwazi ukufinyelela amakhodi ku-DS-A, khona-ke ikhodi ethi U0215 iyikhodi yesikhashana noma ikhodi yememori. Uma i-DS-A ingafinyeleleki, ikhodi ethi U0215 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu iphutha lesifunda elibangela ukuthi inkinobho yomnyango ilahlekelwe amandla noma phansi a.

Hlola wonke amafusi anikezela ngemojula ye-DS-A kule moto. Hlola zonke izisekelo ze-DS-A. Thola izindawo zokuxhuma eziphansi zemoto futhi uqinisekise ukuthi ukuxhumana kuhlanzekile futhi kuvikelekile. Uma kunesidingo, zisuse, thatha ibhulashi elincane le-wire bristle kanye nesisombululo sesoda/amanzi bese uhlanza ngayinye, kokubili isixhumi nalapho ixhuma khona.

Uma kukhona ukulungiswa okwenziwe, sula ama-DTC kunoma imaphi amamojula asetha ikhodi enkumbulweni futhi ubone ukuthi ungakwazi yini ukuxhumana nemojula ye-DS-A. Uma ukuxhumana ne-DS-A kubuyiselwa, inkinga kungenzeka kakhulu ngamafuse/ukuxhumana.

Uma ikhodi ibuya noma ukuxhumana nemojuli kungakatholakali, thola izixhumanisi zokuxhumana zebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-DS-A, esivame ukuba phakathi komnyango okukhulunywa ngawo. Ngaphambi kokunqamula isixhumi ku-DS-A, nqamula ikhebula yebhethri eyinegethivu. 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.

Ngaphambi kokuthi uphinde uxhume izixhumi ku-DS-A, yenza lokhu kuhlola okumbalwa kwamandla kagesi. Uzodinga ukufinyelela kumitha yedijithali ye-volt-ohm (DVOM). Qiniseka ukuthi i-DS-A inamandla nendawo. Finyelela kumdwebo kagesi futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-DS-A. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-DS-A isanqanyuliwe. Xhuma intambo ebomvu ye-voltmeter yakho emandleni e-B+ ngamunye (i-voltage yebhethri) engena kusixhumi se-DS-A, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, itheminali enegethivu yebhethri isebenza njalo). Kufanele ubone inani le-voltage yebhethri. Qiniseka ukuthi unesizathu esihle. Xhuma umthofu obomvu we-voltmeter kuphozithivu yebhethri (B+) kanye nomthofu omnyama kusekethi yaphansi ngayinye. Nakulokhu, kufanele ubone i-voltage yebhethri isikhathi ngasinye 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 ukusula ikhodi yephutha ye-U0215, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto njengoba lokhu kuzobonisa ukwehluleka kwe-DS-A. . Iningi lalawa ma-DS-As kufanele ahlelwe noma alinganiswe ukuze afakwe kahle emotweni.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi ye-U0215?

Uma usadinga usizo nge-DTC U0215, 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.
