Idatha ye-OBD-II DTC

Ukuxhumana Okulahlekile Ngenzwa Yokuvimbela E

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Restraint System Sensor E (RSS-E) 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.

Inzwa yohlelo lokuvimbela e ivame ukutholakala ngemuva kwedeshibhodi, imvamisa maphakathi nendawo yemoto. Yamukela idatha yokufaka evela ezinzwa ezahlukahlukene, ezinye zazo zixhunywe kuyo ngqo, futhi iningi lidluliselwa ngohlelo lokuxhumana ngamabhasi. Okokufaka okubaluleke kakhulu kwalezi zinzwa ukushayisana noma izinzwa zokushayisana. Lokhu okufakwayo kuvumela imodyuli ukuthi inqume ukuthi kwenzeka nini ukushayisana noma lapho imoto imana yehlisa ijubane ngokushesha. Umehluko phakathi kwalokhu ukuthi i-RCM ayikwazi ukuthatha zinyathelo, ingavula ama-seatension pretensioners noma isebenzise labo abazenzela ngaphambili kanye nemigoqo yokuvimbela / ama-airbags.

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

Ukuqina kwekhodi nezimpawu

Ubunzima kuleli cala buhlale bubucayi ngenxa yezinkinga zokuphepha ezivela ohlelweni lokulawula imingcele engasebenzi. Ukuphepha kuwukukhathazeka kwanoma ubani uma usebenzisa lawa masistimu ngoba angaqhubeka nokusebenza ngisho nalapho izibani ezixwayisayo zikhanya. UHLALE uphathe lezi zinhlelo njengokungathi zingasebenza noma nini.

Izimpawu zekhodi ye-U0174 zingafaka:

• Isibani se-Airbag sivuliwe noma siyakhanya

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 isisekelo kumodyuli ye-RSS-E
• 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-U0174 ngaphambi kokuthi noma yimaphi amakhodi amakhulu ahlolwe ngokuphelele futhi enqatshelwe.

Uma ithuluzi lakho lokuskena lingafinyelela kuma-DTC futhi okuwukuphela kwekhodi oyithola kwamanye amamojula ngu-U0174, zama ukufinyelela i-Restraint System Sensor e (RSS-E). Uma ukwazi ukufinyelela amakhodi asuka ku-RSS-E khona-ke ikhodi ethi U0174 iyikhodi yesikhashana noma yememori. Uma i-RSS-E ingafinyeleleki, ikhodi ethi U0174 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma inhlabathi kunzwa yesistimu evimbelayo. E.

Bheka wonke amafuyuzi ahambisa imodyuli ye-RSS-E kule moto. Bheka zonke izizathu ze-RSS-E. Thola izindawo zokumisa 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-U0174 uyabuya noma ungaxhumana nemodyuli ye-RSS-E. Uma kungekho khodi ebuyiswayo noma ukuxhumana kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.

NGAPHAMBI KOKUTHATHA IZINXIBELELWANO ZE-RSS-E, QINISEKISA UKUTHI UHLELO LUVALWA IZINQUBO ZOMKhiqizi! Ngaphandle kwalokho, UMONAKALO ONGENZEKA EMOTWENI NOMA UKULIMALA KOMUNTU NGENXA YOKUQASHWA OKUNGALINDELEKILE KWESIKHWAMA SOMOYA. FUTHI, AMA-AIRBAG AYAQEDWA NGESIKHATHI SOKUHLOLWA OKULANDELAYO NJENGESILINGANISO SOKUGCINA SOKUPHEPHA!

Uma ikhodi ibuya, funa ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-RSS-E, esivame ukutholakala ngemuva kwedeshibhodi. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi kwimodyuli ye-RSS-E. 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 okumbalwa ngaphambi kokuxhuma kabusha izixhumi ku-RSS-E. Uzodinga ukufinyelela ku-digital volt-ohmmeter (DVOM). Qiniseka ukuthi i-RSS-E inikwe amandla futhi isisekelo. Finyelela kumdwebo wiring bese unquma ukuthi amandla amakhulu nokuxhuma komhlaba kufakwe kuphi ku-RSS-E. Xhuma ibhethri ngaphambi kokuqhubeka, i-RSS-E isanqanyuliwe. Xhuma ucingo olubomvu lwe-voltmeter yakho kumthombo ngamunye wamandla we-B + (voltage voltage) oya kusixhumi se-RSS-E, 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 ukuhola okubomvu kusuka ku-voltmeter kuye ku-battery positive (B +) nokuhola okumnyama emhlabathini ngamunye. Nakulokhu futhi, kufanele ubone i-voltage yebhethri njalo lapho uyixhuma. Uma kungenjalo, xazulula inkinga yesekethe yamandla noma yomhlabathi.

Ngaphambi kokuqhubeka, hlola umdwebo wiring bese uhlola ukuthi unayo yini eyodwa noma zombili izifunda zokuxhumana ezihlukile ku-RCM; Yenza amasheke asebenza kumasekethe emotweni yakho.

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.

Bese ubheka ezinye 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 ukusula i-DTC U0174, into kuphela engenziwa ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-RSS-E. . Iningi lalawa ma-RSS-Es kufanele ahlelwe noma alinganiswe ukuze alingane kahle emotweni.
