Ukuxhumana Okulahlekile NgeModyuli B Yokulawula Usizo Lokupaka

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilongwa yohlelo lokuxhumana ejwayelekile esebenza kokuningi nokwenziwa kwezimoto.

Le khodi isho ukuthi imojula yokupaka esiza ukulawula B (PACM-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.

I-PACM-B imvamisa itholakala esiqwini semoto. Yamukela imininingwane yokufaka evela ezinzwa ezahlukahlukene, ezinye zazo zixhunywe kuyo ngqo futhi eziningi zazo zidluliselwa ngohlelo lokuxhumana ngamabhasi. Lokhu kokufaka kuvumela imodyuli ukuthi ikhombise imininingwane kumshayeli mayelana nangemuva kwemoto nokuthi yini eseduze.

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

Ukuqina kwekhodi nezimpawu

Ubulukhuni kuleli cala buphansi ukuba buhambisane ngenxa yezinkinga zokuphepha ezivela ekukwazini kwePACM-B ukudukisa izithiyo zezimoto.

Izimpawu zekhodi ye-U0243 zingafaka:

• Imodyuli yokulawula insiza yokupaka ayibonisi imininingwane / isikrini esingenalutho / izixwayiso

izizathu

Imvamisa isizathu sokufaka le khodi sithi:

• Vula kusifunda se-CAN +
• Vula ebhasini le-CAN - isekethe kagesi
• Isifunda esifushane sokufaka amandla kunoma yisiphi isifunda sebhasi le-CAN
• Mfushane kuya phansi kunoma yisiphi isifunda sebhasi le-CAN
• Awekho amandla noma umhlabathi module ye-PACM-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-U0243 ngaphambi kokuthi noma yimaphi amakhodi amakhulu ahlolwe ngokuphelele futhi enqatshelwe.

Uma ithuluzi lakho lokuskena lingafinyelela amakhodi enkathazo futhi ikhodi eyodwa kuphela oyithola kwamanye amamojula ngu-U0243, zama ukufinyelela i-PACM-B. Uma ukwazi ukufinyelela amakhodi asuka ku-PACM-B, khona-ke ikhodi ethi U0243 iyikhodi yesikhashana noma yememori. Uma i-PACM-B ingafinyeleleki, ikhodi U0243 esethwe ngamanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukulahlekelwa amandla noma umhlabathi ku-PACM-B.

Bheka wonke amafuyuzi ahambisa i-PACM-B kule moto. Bheka zonke izizathu ze-PACM-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-U0243 uyabuya noma ungaxhumana nemodyuli yePACM-B. Uma kungekho khodi ebuyayo noma ukuxhumeka kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.

Uma ikhodi ibuya, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-PACM-B, esivame ukutholakala esiqwini semoto yakho. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-PACM-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 i-dielectric silicone grease lapho kuthinta amatheminali.

Yenza lokhu kuhlolwa kwamandla kagesi ambalwa ngaphambi kokuxhuma kabusha izixhumi ku-PACM-B. Uzodinga ukufinyelela ku-digital volt ohmmeter (DVOM). Qiniseka ukuthi i-PACM-B inamandla nomhlabathi. Finyelela kumdwebo wiring bese unquma ukuthi amandla amakhulu nempahla yomhlaba ingena kuphi ku-PACM-B. Xhuma ibhethri ngaphambi kokuqhubeka ne-PACM-B isanqanyuliwe. Xhuma ucingo olubomvu lwe-voltmeter yakho kumthombo ngamunye wamandla we-B + (voltage voltage) oya kusixhumi se-PACM-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 kungenakwenzeka, noma awukwazanga ukusetha kabusha i-DTC U0243, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-PACM-B. . Iningi lalawa ma-PACM-B kufanele ahlelwe noma acushwe ukuze kufakwe kahle imoto.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi ye-U0243?

Uma usadinga usizo nge-DTC U0243, 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.
