Ukuxhumana Okulahlekile NgeModyuli Yokulawula Ukuthwebula A

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi iCapture Control Module A (ECM-A) 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-Grapple Control Module A (ECM-A) ivame ukutholakala ngemuva kwephaneli elixhumene eduze komnyango okukhulunywa ngawo. Ingafakwa futhi ngaphakathi komnyango okukhulunywa ngawo. Ithola okokufaka okuvela ezinzwa 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 ukuhamba kwamawindi omshayeli / abagibeli. Uma ifakwe, ingakwazi futhi ukulawula ukusebenza kwezikhiye zeminyango kagesi. Bheka incwajana yemoto yakho ukunquma ukuthi imuphi umnyango obhalwe ukuthi “A” esimweni sakho.

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

Ukuqina kwekhodi nezimpawu

Ubukhulu kuleli cala bungaba noma bungabi bukhulu, kuya ngokuthi inkinga ikuphi. Umenzi angalungisa inkinga mathupha uma kwenzeka ukwehluleka kwebhasi. Ukwehluleka ukusebenzisa i-ECM-A akukuthinti ngandlela thile ukusebenza kwemoto.

Izimpawu zekhodi ye-U0239 zingafaka:

• Amawindi omshayeli / abagibeli abhajwe endaweni eyodwa / angahambi
• Izikhiye zikagesi zamawindi okushayela / abagibeli azisebenzi
• I-ECM ayivuli / ayisebenzi
• Isibani sesixwayiso se-airbag kungenzeka sikhanyiswe

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-ECM-A
• 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-U0239 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0239, zama ukufinyelela i-ECM-A. Uma ukwazi ukufinyelela amakhodi kusukela ku-ECM-A, khona-ke ikhodi ye-U0239 kungaba ikhodi yesikhashana noma ikhodi yememori. Uma i-ECM-A ingafinyeleleki, khona-ke ikhodi ye-U0239 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Iphutha elivame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi kumojula yokulawula yokubamba a.

Bheka wonke amafuyuzi ahambisa i-ECM-A kule moto. Bheka konke ukuxhumana komhlaba kwe-ECM-A. 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 ngabe kukhona ukulungiswa okwenziwe, sula ama-DTC kunoma yimaphi amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana nemodyuli ye-ECM-A. Uma ukuxhumana ne-ECM-A kuyalulama, inkinga kungenzeka ngamafusisi / ukuxhumana.

Uma ikhodi ibuya noma ukuxhumana nemodyuli kungakatholakali, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-ECM-A, esivame ukutholakala ngemuva kwe-flap eduze komnyango ohambisanayo. ingafakwa futhi ngaphakathi komnyango okukhulunywa ngawo. Nqamula intambo yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-ECM-A. 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 ambalwa ngaphambi kokuxhuma izixhumi ku-ECM-A. Uzodinga ukufinyelela ku-digital volt-ohmmeter (DVOM). Qiniseka ukuthi i-ECM-A inamandla nomhlabathi. Finyelela kumdwebo wiring bese unquma ukuthi amandla amakhulu nempahla yomhlaba ingena kuphi ku-ECM-A. Xhuma ibhethri ngaphambi kokuqhubeka ne-ECM-A isanqanyuliwe. Xhuma ucingo olubomvu lwe-voltmeter yakho kumthombo ngamunye wamandla we-B + (voltage voltage) oya kusixhumi se-ECM-A, 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.

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 kungenakwenzeka, noma awukwazi ukusula ikhodi yenkathazo ye-U0239, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto njengoba lokhu kuzobonisa ukwehluleka kwe-ECM-A. . Iningi lalawa ma-ECM-As kufanele ahlelwe noma alinganiswe ukuze afakwe kahle imoto.
