U0198 Ukuxhumana Okulahlekile Ne-Telematic Control Module

Idatha ye-OBD-II DTC

Kulahleke Ukuxhumana Nesimo Sokulawula iTelematic

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi imodyuli yokulawula i-telematics (TCM) 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 i-telematics (TCM) ivame ukutholakala ngemuva kwedeshibhodi, imvamisa iphakathi nendawo emotweni. Ingatholakala nasemuva emotweni esiqwini noma egumbini lokugcina langemuva. Ithola okokufaka okuvela ezinhlotsheni ezahlukahlukene, ezinye zazo zixhunywe ngqo kuyo, futhi iningi lithunyelwa ngenqubo yokuxhumana ngamabhasi kusuka kumodyuli wokulawula i-powertrain module (PCM). Lokhu kokufaka kuvumela imodyuli ukuthi ikhombise imininingwane efanelekile yomgwaqo ngokubala indawo yemoto nokuthumela lolu lwazi ngaphezulu kwebhasi ledatha kwimodyuli yokuzula noma kusistimu yensimbi / isistimu enkulu yokubonisa.

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

Ukuqina kwekhodi nezimpawu

Ubukhulu kuleli cala bungaba bucayi uma i-TCM ithumela idatha engalungile kusibonisi semodyuli / isistimu, ngaleyo ndlela inikeze imininingwane engalungile yokuhamba.

Izimpawu zekhodi ye-U0198 zingafaka:

• I-TCM ayihlinzeki ngemininingwane / umsindo / mhlawumbe isikrini esingenalutho
• I-TCM 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 isisekelo se-TCM
• 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-U0198 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0198, zama ukufinyelela i-TCM. Uma ukwazi ukufinyelela amakhodi ku-TCM, khona-ke ikhodi ethi U0198 iyikhodi yesikhashana noma yememori. Uma i-TCM ingafinyeleleki, faka ikhodi ethi U0198 amanye amamojula asethiwe ayasebenza futhi inkinga isivele ikhona.

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

Bheka wonke amafuyuzi ahambisa i-TCM kule moto. Bheka zonke izizathu ze-TCM. 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 ngabe kukhona ukulungiswa okwenziwe, sula ama-DTC kunoma yimaphi amamojula asetha ikhodi kwimemori bese ubona ukuthi usungakwazi yini ukuxhumana ne-TCM. Uma ukuxhumana ne-TCM kululama, inkinga kungenzeka kube yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana nemodyuli kusahluleka, thola ukuxhumana kokuxhumana kwebhasi le-CAN emotweni yakho, ikakhulukazi isixhumi se-TCM, esivame ukutholakala ngemuva kwedeshibhodi, imvamisa maphakathi nemoto. ingatholwa nangemuva emotweni esiqwini noma endaweni yokugcina engemuva. Nqamula ikhebuli yebhethri engeyinhle ngaphambi kokunqamula isixhumi ku-TCM. 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-TCM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-TCM inamandla kanye nomhlabathi. Finyelela kumdwebo wezintambo futhi unqume ukuthi amandla amakhulu nempahla yomhlabathi ingena kuphi ku-TCM. Xhuma ibhethri ngaphambi kokuqhubeka ne-TCM ivaliwe. Xhuma intambo ebomvu ye-voltmeter yakho ku-B+ (i-voltage yebhethri) ngayinye engena kusixhumi se-TCM, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, ukungabi nebhethri kwebhethri 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 zidlula futhi ukuxhumana kungenakwenzeka, noma awukwazanga ukusula i-DTC U0198, into kuphela engenziwa ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzokhomba i-TCM engalungile. Iningi lalawa ma-TCM kufanele ahlelwe noma alinganiswe ukuze afake kahle imoto.
