U0164 Ukuxhumana Okulahlekile Ne-HVAC Control Module

Ikhodi Yenkinga ye-OBD-II - U0164 - Ishidi Ledatha

U0164 - Kulahleke Ukuxhumana Nemojuli Yokulawula ye-HVAC

Isho ukuthini i-DTC U0164?

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

Le khodi isho ukuthi i-HVAC Control Module (HVACCM) 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 ye-HVAC imvamisa itholakala ngemuva kwedeshibhodi, imvamisa maphakathi nemoto, noma ngemuva kwedeshibhodi. Ithola imininingwane yokufaka evela ezinzwa ezahlukahlukene, ezinye zazo zixhunywe kuyo ngqo, iningi lazo lidluliselwa ngohlelo lokuxhumana ngamabhasi. Lokhu kokufaka kuvumela ukuthi imodyuli ilawule izinga lokushisa ngaphakathi kwezimoto, kulokhu kuphela kubagibeli bangaphambili noma ngabagibeli bangaphambili nabangemuva.

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

Qaphela. Endabeni yezimoto zakwaNissan ne-Infiniti, le khodi ingakhombisa ukulahleka kokuxhumana nemitha ehlanganisiwe. Izinyathelo zokuxazulula inkinga zizofana.

Ukuqina kwekhodi nezimpawu

Ubukhulu kuleli cala ngeke bube yinkinga ngenxa yamandla wesipele semodyuli. Uma kuvela inkinga kagesi, imodyuli iyabhekhwa bese iyazenzakalela ukuze isuse isikhundla njengokuvikela ukuphepha.

Izimpawu zekhodi ye-U0164 zingafaka:

• Isibani Sesikhombi Sokungasebenzi Kahle (MIL) sivuliwe
• Imodyuli yokulawula ye-HVAC ayivuli / ayisebenzi

Izimbangela zephutha U0164

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 umhlabathi ku-HVACCM
• Akuvamile - imojula yokulawula inephutha
• Ukuxhumeka kukagesi okungalungile kumojuli yokulawula iluphu ye-HVAC.
  

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-U0164 ngaphambi kokuthi noma yimaphi amakhodi amakhulu ahlolwe ngokuphelele futhi enqatshelwe.

Uma ithuluzi lakho lokuskena lingafinyelela amakhodi enkathazo futhi okuwukuphela kwekhodi oyithola kwamanye amamojula ngu-U0164, zama ukufinyelela imojula yokulawula ye-hvac (HVACCM). Uma ukwazi ukufinyelela amakhodi avela ku-HVACCM, khona-ke ikhodi ethi U0164 iyikhodi yesikhashana noma yememori. Uma i-HVACCM ingafinyeleleki, khona-ke ikhodi ethi U0164 amanye amamojula ayasethwa iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu iphutha lesekhethi eliholela ekulahlekelweni kwamandla noma phansi kumojuli yokulawula ye-HVAC.

Bheka wonke amafuyuzi ahambisa imodyuli ye-HVACCM kule moto. Bheka zonke izizathu ze-HVACCM. 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-U0164 uyabuya yini noma ungaxhumana ne-HVACCM. Uma kungekho khodi ebuyiswayo noma ukuxhumana kubuyisiwe, inkinga kungenzeka ibe yinkinga yefuse / yokuxhuma.

Uma ikhodi ibuya, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-HVACCM, esivame ukutholakala ngemuva kwedeshibhodi / ideshibhodi. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-HVACCM. 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-HVACCM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-HVACCM inamandla nesisekelo. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-HVACCM. Xhuma ibhethri ngaphambi kokuqhubeka ne-HVACCM ivaliwe. Xhuma umthofu obomvu we-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye engena kusixhumi se-HVACCM, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, ukungabi nebhethri kusebenza njalo). 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 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 U0164, into kuphela engenziwa ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe, njengoba lokhu kuzobonisa i-HVACCM engasebenzi. Iningi lalawa ma-HVACCM kumele ahlelwe noma alinganiswe ukuze kufakwe kahle imoto.
