Ukuxhumana Okulahlekile NgeModule Yokulawula Enganciphisi

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi imodyuli yokulawula i-ejenti yokubuyisela (i-RCM) 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.

I-Reductant Control Module (RCM) ivame ukutholakala ngqo ethangini le-Exhaust Fluid noma le-DEF. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo ezixhumeke ngqo kuyo, futhi iningi lidluliswa ngohlelo lokuxhumana ngamabhasi kusuka kumodyuli we-powertrain control module (PCM). Lokhu kokufaka kuvumela imodyuli ukuthi ilawule lapho i-RCM ilawula i-heater yethangi noma iphampu ukufafaza i-DEF epayipini lokukhipha.

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

Ukuqina kwekhodi nezimpawu

Kulesi simo, ubunzima bungaba bukhulu kakhulu, kuya ngokuthi imoto isiqalwe kangaki kulesi simo. Ekugcineni i-RCM / PCM ingangena kumodi yokuqalisa / yokuqalisa.

Izimpawu zekhodi ye-U010E zingafaka:

• Khanyisa Isikhombi Sokungasebenzi (MIL) "Kuvuliwe"
• Injini ingaqala futhi isebenze ngokujwayelekile, kepha lapho nje izinga le-DEF liwela phansi ngokwanele, inkomba ye-DEF izokhanya. Ngemuva kwenombolo ethile yemijikelezo yokuqala, imoto ngeke iqale noma iqale.

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 isisekelo kumodyuli ye-RCM
• 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-U010E ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U010E, zama ukufinyelela i-RCM. Uma ukwazi ukufinyelela amakhodi asuka ku-RCM, khona-ke ikhodi ethi U010E ingeyesikhashana noma iyikhodi yememori. Uma ungakwazi ukufinyelela i-RCM, khona-ke ikhodi ye-U010E esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi kumojula yokulawula i-reductant.

Bheka wonke amafuyuzi ahambisa i-RCM kule moto. Bheka zonke izizathu ze-RCM. 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 ngabe kukhona ukulungiswa okwenziwe, sula ama-DTC kunoma yimaphi amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana ne-RCM. Uma ukuxhumana ne-RCM kululama, inkinga kungenzeka ibe yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana kungasungulwa ngemojuli, thola izixhumanisi zokuxhumana zebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-RCM, esivame ukutholakala ngqo ethangini likadizili noma ethangini lokukhipha ... Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-RCM. 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-RCM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-RCM inamandla nendawo. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-RCM. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-RCM isavaliwe. Xhuma umthofu obomvu we-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye engena kusixhumi se-RCM, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, ibhethri inegethivu njalo 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 zidlula futhi ukuxhumana kungakenzeki noma awukwazanga ukusula i-DTC U010E, into kuphela ongayenza ukufuna usizo kumhloli oqeqeshiwe wezimoto njengoba lokhu kuzobonisa ukwehluleka kwe-RCM. Iningi lala ma-RCM kufanele ahlelwe noma alinganiswe ukuze afake kahle imoto.

Izingxoxo ezihlobene ze-DTC

• IMercedes Benz R350 Code u010eSawubona, ngabe kukhona umuntu owake wasebenzisana nale khodi ngaphambili. NgineMercedes Benz R350 nekhodi u010e. Ngabe ukhona olungise le nkinga ngaphambi ... ngiyabonga ... 

Udinga usizo olwengeziwe ngekhodi U010E?

Uma usadinga usizo nge-DTC U010E, 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.
