Ukuxhumana Okulahlekile NgeModyuli Yokulawula Ikholomu Yokuqondisa

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi imodyuli yokulawula ikholomu yokuqondisa (i-SCCM) 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.

Imodyuli yokulawula ikholomu yokuqondisa (SCCM) imvamisa itholakala ngaphakathi kwekholamu yokuqondisa. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo ezixhunywe ngqo kuyo, futhi iningi lidluliswa ngohlelo lokuxhumana ngamabhasi kusuka kumodyuli we-powertrain control module (PCM). Lokhu kokufaka kuvumela imodyuli ukwazisa amanye amamojula ngebhasi le-CAN mayelana nokuma kwesondo lokushayela. Lokhu kuthinta ukusebenza kohlelo lokuqondisa, izinguquko ohlelweni lokumiswa futhi, okubaluleke kakhulu, kuyadingeka ku-Electronic Stability Control (ESC). I-ESC igcina ukuqina kwemoto kuzo zonke izimo zokushayela, noma ngabe kupavumente emanzi noma ngesikhathi sokushayela okunolaka.

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

Ukuqina kwekhodi nezimpawu

Ubukhulu kuleli cala buxhomeke ohlelweni. Njengoba ukuhamba kwamandla kagesi kungukuphela kokuqondisa kwamandla emoto, ukunakekelwa kufanele kuhlale kwenziwa ngalesi simiso. Ngaphezu kwalokho, ukuphepha kwalezi zinhlelo kuyinkinga ngoba uma kwenzeka ukwehluleka kwalezi zinhlelo, amandla kagesi angatholakali.

Umenzi angahlinzeka nge-workaround yesandla uma kwenzeka ukwehluleka okuphelele kagesi / mathupha. Ukuntuleka kokusebenza kwe-SCCM kungathinta noma kungathikamezi ukusebenza kwezimoto.

Izimpawu zekhodi ye-U0212 zingafaka:

• I-SCCM ayivuli noma ayisebenzi
• Izinkomba ze-ABS / TRAC zivuliwe noma ziyakhanya
• Isibani sesibonisi se-ESP / ESC sivuliwe (kuya ngomkhiqizi)
• Isikhombi Sokungasebenzi (MIL) SIVULIWE

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-SCCM
• 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-U0212 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0212, zama ukufinyelela ku-SCCM. Uma ukwazi ukufinyelela amakhodi avela ku-SCCM, khona-ke ikhodi ethi U0212 iyikhodi yesikhashana noma yememori. Uma i-SCCM ingafinyeleleki, khona-ke ikhodi ethi U0212 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu iphutha lesekethe eliholela ekulahlekelweni kwamandla noma phansi kumojula yokulawula ikholomu yokuqondisa.

Bheka wonke amafuyuzi ahambisa i-SCCM kule moto. Bheka zonke izizathu ze-SCCM. 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-DTC kunoma yimaphi amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana ne-SCCM. Uma ukuxhumana ne-SCCM kululama, inkinga kungenzeka ibe yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana nemodyuli kungakatholakali, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-SCCM, esivame ukutholakala ngaphakathi kwekholamu yokuqondisa. Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-SCCM. 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-SCCM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-SCCM inamandla nesisekelo. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nezinto ezitholakala phansi zingena kuphi ku-SCCM. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-SCCM isavaliwe. Xhuma intambo ebomvu ye-voltmeter yakho ku-B+ ngayinye (i-voltage yebhethri) engena kusixhumi se-SCCM, 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 ziphumelela futhi nokuxhumana kungenakwenzeka noma awukwazanga ukusula i-DTC U0212, into kuphela engenziwa ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto njengoba lokhu kuzobonisa ukwehluleka kwe-SCCM. Iningi lala ma-SCCM kumele ahlelwe noma alinganiswe ukuze afake kahle imoto.
