Ukuxhumana Okulahlekile Nemojuli Yokuqala Ekude

Kusho ukuthini lokhu?

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

Le khodi isho ukuthi i-Remote Start Module (RSM) 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-Remote Start Module (RSM) ngokuvamile itholakala ngemuva kwedeshi nhlangothi zombili zemoto. 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 ilawule imojula yokulawula ukudluliswa kanye nesekhethi yokuqalisa isiqalo ukusuka kuma-fobs wokhiye akude.

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.

Izimpawu zekhodi ye-U0254 zingafaka:

• Injini ngeke iqale ngesilawuli kude
• Imoto ngeke iqale / ngeke iqale
• Isibani sesibonakaliso sephutha sivuliwe

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 kumodyuli ye-RSM
• 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-U0254 ngaphambi kokuthi noma yimaphi amakhodi ayisisekelo ahlolwe kahle futhi alungiswe.

Uma okuwukuphela kwekhodi oyithola kwamanye amamojula ingu-U0254, zama ukufinyelela i-RSM. Uma ukwazi ukufinyelela amakhodi asuka ku-RSM, khona-ke ikhodi ethi U0254 iyikhodi yesikhashana noma yememori. Uma i-RSM ingafinyeleleki, ikhodi ethi U0254 esethwe amanye amamojula iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukwehluleka kwesekethe okuholela ekulahlekelweni kwamandla noma phansi kumojula yokuqala yesilawuli kude.

Bheka wonke amafiyuzi ahambisa i-RSM kule moto. Bheka zonke izizathu ze-RSM. 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-RSM. Uma ukuxhumana ne-RSM kululama, inkinga kungenzeka ibe yinkinga yokuxhuma / yokuxhuma.

Uma ikhodi ibuya noma ukuxhumana nemojuli kungakatholakali, thola ukuxhumana kwebhasi le-CAN emotweni yakho, okubaluleke kakhulu isixhumi se-RSM, esivame ukutholakala ngemuva kwedeshibhodi nhlangothi zombili zemoto. Nqamula ikhebula lebhethri elinegethivu ngaphambi kokunqamula isixhumi ku-RSM. 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-RSM. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi i-RSM inamandla kanye nomhlabathi. Finyelela kumdwebo wokufaka izintambo bese unquma ukuthi amandla amakhulu nempahla yaphansi ingena kuphi ku-RSM. Xhuma kabusha ibhethri ngaphambi kokuqhubeka ne-RSM isavaliwe. Xhuma umthofu obomvu we-voltmeter yakho ku-B+ ngayinye (i-voltage yebhethri) engena kusixhumi se-RSM, kanye nomthofu omnyama we-voltmeter yakho endaweni enhle (uma ungaqiniseki, ukungabi nebhethri 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 ukusetha kabusha i-DTC U0254, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto, njengoba lokhu kuzobonisa ukwehluleka kwe-RSM. Iningi lalawa ma-RSM kufanele ahlelwe noma alinganiswe ukuze kufakwe kahle imoto.

Izingxoxo ezihlobene ze-DTC
