Ukuxhumana Okulahlekile Nebhodi Le-Treadmill Imojuli Yokulawula

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi iFootrest Control Module A (RBCM-A) 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.

I-Footrest Control Module A (RBCM-A) ivamise ukuba ngemuva kwedeshi nhlangothi zombili zemoto. Ingafakwa futhi ngaphakathi kwe-centre console. Ithola okokufaka okuvela ezinzwa ezihlukahlukene, ezinye zazo ezixhunywe kuyo ngokuqondile, futhi eziningi zithunyelwa ngohlelo lokuxhumana lwebhasi lusuka kumojula yokulawula i-powertrain (PCM). Lokhu okokufaka kuvumela imojula ukuthi ilawule ukwenziwa kusebenze kwezindawo zokuphumula / ukukhanya kwe-footrest lapho iminyango ivulwa noma ivaliwe. Bheka ibhukwana lakho lemoto ukuze uthole ukuthi yimuphi umnyango obhalwe ukuthi "A" esimweni sakho esithile.

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

Ukuqina kwekhodi nezimpawu

Ukungathí sina kuleli cala akukaze kube bucayi, njengoba lokhu kuyithuluzi lokusebenziseka kalula kwamakhasimende futhi uma kwenzeka ukuphelelwa amandla okuphelele, kuhlale kunomsebenzi owenziwe ngesandla. Ukuntuleka kokusebenza kwe-RBCM-A akuthinti nganoma iyiphi indlela ukusebenza kwemoto.

Izimpawu zekhodi ye-U0244 zingafaka:

• Izinyawo zihlala zinwetshiwe / azihoxiswanga
• Ukukhanya kwebhodi eligijimayo kuhlala kuvuliwe / akukaze kukhanye
• I-RBCM-A ayivuli / 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 indawo ye-RBCM-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-U0244 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0244, zama ukufinyelela i-RBCM-A. Uma ukwazi ukufinyelela amakhodi asuka ku-RBCM-A khona-ke ikhodi ethi U0244 iyikhodi yesikhashana noma yememori. Uma ungakwazi ukufinyelela i-RBCM-A, ikhodi U0244 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi kumojula yokulawula i-treadmill a.

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

Uma kukhona ukulungiswa okwenziwe, sula ama-DTC kunoma imaphi amamojula asetha ikhodi enkumbulweni futhi ubone ukuthi ungakwazi yini ukuxhumana manje nemojuli ye-RBCM-A. Uma ukuxhumana ne-RBCM-A kuyalulama, inkinga kungenzeka ukuthi iyinkinga ye-fuse/yokuxhumana.

Uma ikhodi ibuya noma ukuxhumana nemojula kungakaqiniseki, thola ukuxhumana kwebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-RBCM-A, esivame ukutholakala ngemuva kwedeshibhodi, nhlangothi zombili zemoto. ingafakwa futhi ngaphakathi kwe-centre console. Nqamula intambo yebhethri enegethivu ngaphambi kokunqamula isixhumi ku-RBCM-A. 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 kabusha izixhumi ku-RBCM-A. Uzodinga ukufinyelela ku-digital volt ohmmeter (DVOM). Qiniseka ukuthi i-RBCM-A inamandla nesisekelo. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu noxhumo lomhlabathi kungena kuphi ku-RBCM-A. Xhuma ibhethri ngaphambi kokuqhubeka ne-RBCM-A isanqanyuliwe. Xhuma intambo ebomvu ye-voltmeter yakho kumthombo wamandla ngamunye ongu-B + (ibhethri) ongena kusixhumi se-RBCM-A, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, isigxobo esinegethivu sebhethri sihlala sisebenza). Kufanele ubone ukufundwa kwe-voltage yebhethri. Qiniseka ukuthi unesizathu esihle. Xhuma intambo ebomvu ukusuka ku-voltmeter iye kubhethri positive (B +) kanye nentambo emnyama emhlabathini ngamunye. Nakulokhu, kufanele ubone i-voltage yebhethri isikhathi ngasinye lapho uyixhuma. Uma kungenjalo, xazulula inkinga yamandla 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 U0244, into kuphela ongayenza ukufuna usizo kuchwepheshe wokuxilonga izimoto oqeqeshiwe, njengoba lokhu kuzobonisa ukwehluleka kwe-RBCM-A. . Iningi lalawa ma-RBCM-A kufanele ahlelwe noma alinganiswe ukuze alingane kahle emotweni.
