Idatha ye-OBD-II DTC

Ukuxhumana Kulahlekile Ngemojula Yokulawula Idrayivu Yamasondo Amane

Kusho ukuthini lokhu?

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

Le khodi ichaza ukuthi imodule yokulawula amasondo amane (AWDCM) namanye amamojula okulawula emotweni awaxhumani. Umjikelezo osetshenziswa kakhulu ekuxhumaneni waziwa ngokuthi i-Controller Area Bus communication, noma 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.

Imojula yokulawula amasondo amane (AWDCM) ivamise ukutholakala ngemuva kwedeshibhodi, imvamisa eduze kweswishi yokushayela. Ingase futhi ibekwe ngaphansi kwegumbi labagibeli, eduze necala lokudlulisa. Ingase futhi ibe yingxenye ye-PCM. Ithola okokufaka okuvela ezinhlobonhlobo zezinzwa, ezinye zazo ezixhunywe kuyo ngokuqondile, futhi eziningi zithunyelwa ngohlelo lokuxhumana lwebhasi lusuka kumojula yokulawula i-powertrain (PCM). Lokhu okokufaka kuvumela imojula ukuthi ilawulwe njengohlelo lokusebenza lwe-powertrain, mhlawumbe noma uhlelo lokushayela amasondo amabili noma amane. Ingakwazi futhi ukushintsha isilinganiso segiya elisetshenziswa kuma-axle okushayela kanye nenani le-torque elisetshenziswa ku-transmission.

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

Ukuqina kwekhodi nezimpawu

Ubunzima kuleli cala abukho bucayi ngoba i-PCM inesu lokulondoloza uma ilahlekelwa ukuxhumana ne-AWDCM.

Izimpawu zekhodi ye-U011D zingafaka:

• Isibani senkomba yokulawula ukudonsa sivuliwe noma siyakhanya, kuya ngohlelo
• Bheka ukuthi ilambu lokumisa livuliwe yini, kuye ngohlelo.

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 umhlabathi ku-AWDCM
• 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-U011D ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U011D, zama ukufinyelela ku-AWDCM. Uma ukwazi ukufinyelela amakhodi avela ku-AWDCM khona-ke ikhodi ethi U011D iyikhodi yesikhashana noma yememori. Uma i-AWDCM ingafinyeleleki, ikhodi ethi U011D esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi kumojula yokulawula ye-AWD.

Bheka wonke amafusi anikezela nge-AWDCM kule moto. Bheka zonke izizathu ze-AWDCM. Thola izindawo zokubambelela phansi emotweni futhi uqinisekise ukuthi izixhumo zihlanzekile futhi zivikelekile. Uma kunesidingo, zisuse, thatha ibhulashi elincane le-wire bristle ne-baking soda / isisombululo samanzi bese uhlanza ngayinye, kokubili isixhumi nendawo lapho ixhuma khona.

Uma kukhona ukulungiswa okwenziwe, sula i-DTCs kunoma imaphi amamojula asetha ikhodi enkumbulweni futhi ubone ukuthi ungakwazi yini ukuxhumana ne-AWDCM. Uma ukuxhumana ne-AWDCM kuyalulama, inkinga kungenzeka ukuthi iyinkinga ye-fuse/yokuxhumana.

Uma ikhodi ibuya noma ukuxhumana nemojula kungakaqiniseki, thola izixhumanisi zokuxhumana zebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-AWDCM, esivame ukutholakala ngemuva kwedeshibhodi, ngokuvamile eduze neswishi yokushayela. Ingase futhi ibe ngaphansi kwegumbi labagibeli, eduze kwecala lokudlulisa. ingaba yingxenye ye-RMB. Nqamula intambo yebhethri enegethivu ngaphambi kokunqamula isixhumi ku-AWDCM. Uma usutholakele, bheka ngokubukeka izixhumi nezintambo. Bheka imihuzuko, ama-scuffs, izintambo eziveziwe, izimpawu zokusha, noma ipulasitiki encibilikisiwe.

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-AWDCM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-AWDCM inamandla kanye nomhlabathi. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nemithombo yaphansi ingena kuphi ku-AWDCM. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-AWDCM isavaliwe. Xhuma umthofu obomvu we-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye engena kusixhumi se-AWDCM, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, i-negative yebhethri ihlala isebenza). 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 ukusetha kabusha i-DTC U011D, into kuphela engenziwa ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-AWDCM. Iningi lalawa ma-AWDCM kufanele ahlelwe noma alinganiswe ukuze afake kahle imoto.
