Ukuxhumana Okulahlekile NgeModuli Yesitimela Esishisayo

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi imodyuli yesiteringi esishisayo (HSWM) 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-Heated Steering Wheel Module (HSWM) ivame ukutholakala ngaphakathi kwekholomu yokuqondisa. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo zixhunywe ngqo kuyo, futhi iningi lithunyelwa ngenqubo yokuxhumana ngamabhasi kusuka kumodyuli wokulawula i-powertrain module (PCM). Lokhu kokufaka kuvumela imodyuli ukuthi ilawule into yokushisa ngaphakathi kwesiteringi.

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

Ukuqina kwekhodi nezimpawu

Ubucayi kuleli cala abukaze bube bucayi, ngoba lokhu kuyithuluzi lokusizakala kwamakhasimende, futhi uma kwenzeka uphela amandla kagesi, kuhlale kukhona ukusebenza ngezandla. Ukungabikho komsebenzi we-HSWM akuphazamisi nakancane ukusebenza kwemoto.

Izimpawu zekhodi ye-U0229 zingafaka:

• I-element ye-rudder ayishisi (iyavula)
• Ukushisa kwesondo lokushayela kuhlale kuvuliwe
• I-HSWM ngeke ivule / ayisebenzi

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 se-HSWM module
• 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-U0229 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0229, zama ukufinyelela ku-HSWM. Uma ukwazi ukufinyelela amakhodi avela ku-HSWM, khona-ke ikhodi ethi U0229 iyikhodi yesikhashana noma yememori. Uma ungakwazi ukufinyelela i-HSWM, faka ikhodi ethi U0229 amanye amamojula afakiwe iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu iphutha lesekhethi elinqamula amandla noma phansi kumojuli yesondo lokuqondisa elishisayo.

Bheka wonke amafuyuzi ahambisa i-HSWM kule moto. Bheka zonke izizathu ze-HSWM. 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 amakhodi ezinkinga zokuxilonga kusuka kunoma yimaphi amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana nemodyuli ye-HSWM. Uma ukuxhumana ne-HSWM kululama, inkinga kungenzeka ibe yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana nemodyuli kusahluleka, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-HSWM, esivame ukutholakala ngaphakathi kwekholamu yokuqondisa. Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-HSWM. 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-HSWM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-HSWM inamandla kanye nomhlabathi. Finyelela kumdwebo kagesi futhi unqume ukuthi amandla amakhulu nezizathu zingena kuphi ku-HSWM. Xhuma ibhethri ngaphambi kokuqhubeka ne-HSWM ivaliwe. Xhuma umthofu obomvu we-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye efakwe kusixhumi se-HSWM, 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 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 ukusetha kabusha i-DTC U0229, into kuphela ongayenza ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe, njengoba lokhu kuzobonisa ukwehluleka kwe-HSWM. Iningi lalawa ma-HSWM kufanele ahlelwe noma alinganiswe ukuze alingane kahle nemoto.
