Ukuxhumana Okulahlekile NgeModyuli Yokulawula Ukukhanyisa Emuva B

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Rear Light Control Module B (LCMR-B) namanye amamojula wokulawula emotweni axhumani. Izifunda ezijwayele ukusetshenziswa kakhulu kwezokuxhumana zaziwa ngokuthi yi-Controller Area Bus communication, noma nje ibhasi le-CAN.

Ngaphandle kwaleli bhasi le-CAN, amamojula wokulawula awakwazi ukuxhumana futhi ithuluzi lakho lokuskena lingahle lingalutholi ulwazi oluvela emotweni, kuya ngokuthi isiphi isifunda esibandakanyekayo.

Imodyuli yokulawula ukukhanyisa ngemuva b imvamisa itholakala ngemuva kwedeshibhodi kepha itholakala ngaphakathi kwesiqu. Yamukela idatha yokufaka evela ezinzwa ezahlukahlukene, ezinye zazo ezixhunywe kuyo ngqo, futhi eziningi zidluliselwa ngohlelo lokuxhumana ngamabhasi. Lokhu kokufaka kuvumela imodyuli ukuthi ilawule ukukhanyisa ngemuva emotweni. Bheka incwajana yemoto yakho ukunquma ukuthi yimuphi umnyango obhalwe ukuthi “B” esimweni sakho.

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 kumodyuli engakhanyi ngemuva kwemoto.

Izimpawu zekhodi ye-U0252 zingafaka:

• Akukho ukukhanyisa emuva / ukukhanyisa okuyingxenye
• Isibani Sesikhombi Sedeshi / Semilayezo Sikhanya

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-LCMR-B
• Akuvamile - imojula yokulawula inephutha

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Okokuqala, funa amanye ama-DTC. Uma okunye kwalokhu ukuxhumana kwebhasi noma ibhethri / ukuthungela okuhlobene, kuxilonge kuqala. I-Misdiagnosis iyaziwa ukuthi kungenzeka uma uthola ikhodi ye-U0252 ngaphambi kokuthi noma yimaphi amakhodi amakhulu ahlolwe ngokuphelele futhi enqatshelwe.

Uma ithuluzi lakho lokuskena lingafinyelela amakhodi enkathazo futhi ikhodi okuwukuphela kwayo oyithola kwamanye amamojula ngu-U0252, zama ukufinyelela ku-b ongemuva wemojuli yokulawula ukukhanyisa (LCMR-B). Uma ukwazi ukufinyelela amakhodi asuka ku-LCMR-B khona-ke ikhodi ethi U0252 iyikhodi yesikhashana noma yememori. Uma i-LCMR-B ingafinyeleleki, ikhodi U0252 esethwe ngamanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesifunda okuholela ekulahlekelweni kwamandla noma emhlabathini ngemuva kwemojula yokulawula ukukhanya. b.

Bheka wonke amafuyuzi ahambisa imodyuli ye-LCMR-B kule moto. Bheka zonke izizathu ze-LCMR-B. 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-DTCs kwimemori bese ubona ukuthi u-U0252 uyabuya noma ungaxhumana nemodyuli ye-LCMR-B. Uma kungekho khodi ebuyiswayo noma ukuxhumana kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.

Uma ikhodi ibuya, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-LCMR-B, esivame ukutholakala ngemuva kwedeshibhodi kepha sitholakala ngaphakathi kwesiqu. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi kwimodyuli ye-LCMR-B. 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 kuhlolwa kwamandla kagesi ambalwa ngaphambi kokuxhuma izixhumi ku-LCMR-B. Uzodinga ukufinyelela ku-digital volt-ohmmeter (DVOM). Qiniseka ukuthi i-LCMR-B inamandla nomhlabathi. Finyelela kumdwebo wiring bese unquma ukuthi amandla aphansi kanye nempahla yomhlaba ingena kuphi ku-LCMR-B. Xhuma ibhethri ngaphambi kokuqhubeka ne-LCMR-B isanqanyuliwe. Xhuma ucingo olubomvu lwe-voltmeter yakho kumthombo ngamunye wamandla we-B + (voltage voltage) oya kusixhumi se-LCMR-B, kanye nocingo olumnyama lwe-voltmeter yakho emhlabathini omuhle (uma ungaqiniseki, isigxobo esibi sebhethri sihlala sisebenza). Kufanele ubone ukufundwa kwamandla kagesi webhethri. Qiniseka ukuthi unesizathu esihle. Xhuma ucingo olubomvu kusuka ku-voltmeter kuye ku-battery positive (B +) kanye nocingo olumnyama emhlabathini ngamunye. Nakulokhu futhi, kufanele ubone i-voltage yebhethri njalo lapho uyixhuma. Uma kungenjalo, xazulula inkinga yesekethe yamandla noma yomhlabathi.

Bese uhlola izifunda ezimbili zokuxhumana. Thola i-CAN B+ (noma isekethe ye-MSCAN +) kanye ne-CAN B- (noma isekethe ye-MSCAN). Ngentambo emnyama ye-voltmeter exhunywe endaweni ekahle, xhuma intambo ebomvu ku-CAN B+. Uma ukhiye uvuliwe futhi injini icishiwe, kufanele ubone i-voltage engaba ngu-0.5 volts enokuguquguquka okuncane. Bese uxhuma umthofu obomvu we-voltmeter kusekethe ye-CAN B. Kufanele ubone cishe ama-volts angu-4.4 ngokuguquguquka okuncane.

Uma zonke izivivinyo zidlula futhi ukuxhumana kungakenzeki, noma awukwazanga ukusetha kabusha i-DTC U0252, into kuphela ongayenza ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe, njengoba lokhu kuzobonisa i-LCMR-B ehlulekile. . Iningi lalawa ma-LCMR-B kufanele ahlelwe noma alinganiswe ukuze kukhwezwe kahle imoto.
