Ukuxhumana Kulahlekile Ngemodyuli Yekhamera Engemuva

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi imodyuli yekhamera yangemuva (i-CMR) 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 yekhamera yangemuva (i-CMR) imvamisa itholakala ngemuva kwephaneli elingemuva noma isembozo somboko / wedeski elingemuva, mhlawumbe esiqwini. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo ezixhumeke ngqo kuyo, futhi iningi lidluliswa ngohlelo lokuxhumana ngamabhasi kusuka kumodyuli we-powertrain control module (PCM). Lokhu kokufaka kuvumela imodyuli ukuthi inqume ibanga eliphakathi kwemoto nanoma iyiphi into engemuva kwayo. Futhi kunikeza ukumelwa okubonakalayo kokusemuva kwemoto lapho isikhethi segiya sibuyela emuva.

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 ukwehluleka kwamandla okuphelele, kuhlale kukhona ukusebenza ngezandla. Ukuntuleka kokusebenza kwe-CMR akuphazamisi ukusebenza kwemoto nganoma iyiphi indlela.

Izimpawu zekhodi ye-U0264 zingafaka:

• Ithoni yedeshibhodi / i-CMR
• Ikhamera ivuliwe uma ingekho emuva
• Ikhamera ayivuli / awukho umsindo lapho usondela entweni etholakele

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 module ye-CMR
• 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-U0264 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0264, zama ukufinyelela i-CMR. Uma ukwazi ukufinyelela amakhodi ku-CMR, khona-ke ikhodi ethi U0264 iphakathi noma iyikhodi yememori. Uma ungakwazi ukufinyelela i-CMR, faka ikhodi ethi U0264 amanye amamojula asethiwe ayasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi ngemuva kwemojuli yekhamera.

Bheka wonke amafuyuzi ahambisa imodyuli ye-CMR kule moto. Hlola zonke izizathu zokuthola i-CMR. 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 kuwo wonke amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana nemodyuli ye-CMR. Uma ukuxhumana ne-CMR kululama, inkinga kungenzeka ibe yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana nemodyuli kungakatholakali, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi seCMR, esivame ukutholakala ngemuva kwephaneli langemuva noma isembozo somgqomo / wedokodo langemuva, mhlawumbe esiqwini. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-CMR. 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-CMR. Uzodinga ukufinyelela ku-digital volt ohmmeter (DVOM). Qiniseka ukuthi i-CMR inamandla nomhlabathi. Finyelela kumdwebo wiring bese unquma ukuthi amandla amakhulu nokuxhuma komhlaba kuya kuphi ku-CMR. Phinda uxhume ibhethri ngaphambi kokuqhubeka, i-CMR isakhubazekile. Xhuma ucingo olubomvu lwe-voltmeter kumthombo ngamunye wamandla we-B + (voltage voltage) oya kusixhumi se-CMR, kanye nocingo olumnyama lwe-voltmeter emhlabathini omuhle (uma ungaqiniseki, isigxobo esibi sebhethri sihlala sisebenza). Kufanele ubone ukufundwa kwamandla kagesi webhethri. Qiniseka ukuthi unesizathu esihle. Xhuma ucingo olubomvu kusuka ku-voltmeter kuye ku-battery positive (B +) kanye nocingo olumnyama 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 nokuxhumana kungenzeki, noma awukwazanga ukusetha kabusha i-DTC U0264, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto njengoba lokhu kuzobonisa ukwehluleka kwe-CMR. Iningi lalawa ma-CMR kufanele ahlelwe noma alinganiswe ukuze kufakwe kahle imoto.

Izingxoxo ezihlobene ze-DTC
