Ikhodi ye-U1000 ye-Nissan GM - Ulayini Wokuxhumana we-CAN - Ukungasebenzi Kwesiginali

26.05.2022 /

Imvamisa inkinga nge-U1000 yakwaNissan iyindawo embi yokufaka izintambo. Umbiko wesevisi ukhona wamamodeli alandelayo akwaNissan anekhodi ethi U1000: 

  • - Nissan Maxima 2002-2006 
  • - Nissan Titan 2004-2006. 
  • - Nissan Armada 2004-2006. 
  • - Nissan Sentra 2002-2006. 
  • – Nissan Frontier 2005-2006.
  • – Nissan Xterra 2005-2006 g. 
  • - Nissan Pathfinder 2005-2006. 
  • - Nissan Quest 2004-2006. - 2003-2006.
  • - Nissan 350Z - 2003-2006. 

Xazulula inkinga ye - Hlanza / qinisa izixhumanisi zomhlabathi ze-ECM. - Hlanza / qinisa kabusha uxhumano lwezindlu zekhebula lebhethri olunegethivu kanye noxhumo lwebhethri. – Uma kudingekile, hlanza futhi uhlole ukuthintana okuhle phakathi kwekholomu yokuqondisa kanye nokuhlangana komlenze wesokunxele. Kusho ukuthini?

Ikhodi Yenkinga ye-OBD-II - U1000 - Ishidi Ledatha

I-GM: Isimo sokuhluleka kokuxhumana sekilasi lesi-2 I-Infiniti: Ulayini wokuxhumana we-CAN - ukwehluleka kwesignali Isuzu: Ikilasi le-ID lesixhumanisi 2 alitholakali I-Nissan: CAN zokuxhumana isekethe

I-CAN (Inethiwekhi Yendawo Yokulawula) iwumugqa wokuxhumana we-serial wezinhlelo zokusebenza zesikhathi sangempela. Kuyisixhumanisi sokuphindaphinda esisemoyeni esinezinga eliphezulu ledatha namandla amahle kakhulu okuthola amaphutha. Kunamayunithi amaningi okulawula ama-elekthronikhi afakwe emotweni, futhi iyunithi yokulawula ngayinye ishintshisana ngolwazi futhi ixhumana namanye amayunithi okulawula phakathi nokusebenza (hhayi ukuzimela). Ngokuxhumana kwe-CAN, amayunithi okulawula axhunywe imigqa yokuxhumana emibili (umugqa we-CAN H, umugqa we-CAN L), ohlinzeka ngesivinini esikhulu sokudlulisa ulwazi ngoxhumo olumbalwa.

Iyunithi yokulawula ngayinye idlulisela/ithola idatha, kodwa ikhetha ukufunda kuphela idatha eceliwe.

Isho ukuthini ikhodi u-U1000 kwaNissan?

Lena ikhodi yenethiwekhi yomkhiqizi. Izinyathelo ezithile zokuxazulula inkinga zizohluka kuye ngemoto.

Ikhodi yokungasebenzi U1000 - lena ikhodi yemoto ethile, etholakala kakhulu ezimotweni I-Chevrolet, i-GMC ne-Nissan. Lokhu kubhekisela "ekuhlulekeni kokuxhumana kwesigaba 2". Ngokuvamile, le khodi yandulela ikhodi eyengeziwe ekhomba imojuli noma indawo enephutha. Ikhodi yesibili ingase ibe ijenerikhi noma imoto ethile.

Iyunithi yokulawula ye-elekthronikhi (ECU), okuyikhompyutha yemoto ephazamisekile, ayikwazi ukuxhumana nemojuli noma uchungechunge lwamamojula. Imojuli imane iyithuluzi okuthi, uma liyalwa ukuba lenze njalo, lenze isenzo noma ukunyakaza ngendlela encomekayo.

I-ECU idlulisela imiyalo yayo kumamojula ngenethiwekhi yezintambo ze-"CAN-Bus" (Controller Area Network), ngokuvamile ezitholakala ngaphansi kukakhaphethi. Imoto okungenani inamanethiwekhi amabhasi e-CAN amabili. Ibhasi ngalinye le-CAN lixhunywe kumamojula amaningi ahlukene kuyo yonke imoto.

Inethiwekhi yezokuxhumana yamabhasi e-CAN yasungulwa nguRobert Bosch futhi yaqala ukubonakala ezimotweni ngo-2003. Kusukela ngo-2008, zonke izimoto zifakwe amanethiwekhi amabhasi e-CAN.

Inethiwekhi yokuxhumana yamabhasi e-CAN ihlinzeka ngokuxhumana ngesivinini esiphezulu kakhulu ne-ECM namamojula ahlotshaniswa nayo, okuwenza asebenzisane. Imojuli ngayinye inekhodi yayo yokuhlonza futhi ithumela amasiginali anakhodi kanambambili ku-ECM.

Isiqalo esingu-0 noma esingu-1 sinquma ukuphuthuma noma isikali esibalulekile sesignali. Okungu-0 kuyaphuthuma futhi kudinga impendulo esheshayo, kuyilapho u-1 engaphuthumi kangako futhi angazungeziswa kuze kunciphe ithrafikhi. Amakhodi omsebenzi wemojuli alandelayo azomelwa njengamabhithi anambambili abonakala ku-oscilloscope njengegagasi le-sine eliyisikwele, ukuphakama kwegagasi kube okuphakathi lapho i-ECM ihlanganisa khona isiginali futhi inquma isu lemojuli.

Isizathu sokuthi le khodi ivele kuncike emotweni. Ikhodi yesibili ikhomba ingxenye enesici noma indawo lapho ukungasebenzi kwenzeke khona. Le khodi icacise kakhulu ukuthi ama-bulletins ezinsizakalo zobuchwepheshe (ama-TSBs) akumele ahlolwe hhayi kuphela uphawu lwemoto, kodwa futhi nemodeli ethile kanye nezinketho ezitholakalayo zokuhlolwa okunembile.

Sengivivinye izimoto eziningi zakwaNissan ezinekhodi U1000, ebezipakwe ngokwehlukana. Azikho izinkinga ezitholakele kunoma yiziphi izinhlelo, kepha ikhodi isindile. Le khodi ibinganakwa nje, ebingakhombisi ukungabi bikho kwezinkinga zokushayela noma zokusebenza.

Ezinye izimoto zincoma ukuthi ushintshe i-ECM ngoba lesi yisona sizathu esenza le khodi ivele kule moto. Ezinye zingadala ukuthi i-variable speed wiper motor yehluleke. Endabeni yeNissan TSB eyodwa eyaziwayo, ukulungiswa ukulungisa nokuqinisa ukuxhumana kwe-wiring komhlaba.

I-ECM namamojula alala lapho ukhiye ucishiwe ukunciphisa umthwalo kubhethri. Amamojula amaningi alala ngaphakathi kwemizuzwana noma imizuzu embalwa ngemuva kokucisha. Isikhathi sisethwe ngaphambilini, futhi lapho i-ECM ikhipha umyalo wokulala, uma ngabe idivayisi ingacimi phakathi kwemizuzwana emi-5 ngemuva komyalo, noma umzuzwana owodwa ongeziwe uzosetha le khodi.

Izizathu ezingenzeka zekhodi U1000 NISSAN:

Izindleko zokuxilonga ikhodi engu-U1000 NISSAN

Izindleko zokuxilonga ikhodi ethi U1000 NISSAN yihora elingu-1,0 lomsebenzi. Izindleko zomsebenzi wokukhanda izimoto zincike endaweni, ukwenziwa kanye nemodeli yemoto yakho, ngisho nohlobo lwenjini yakho. Izitolo eziningi zemizimba zikhokhisa phakathi kuka-$30 no-$150 ngehora.

Itholakala kuphi inzwa ye-U1000?

Iphi inzwa ye-U1000

Isithombe esingenhla sibonisa ukumelwa okwenziwe lula kokuthi isistimu yebhasi ye-CAN ixhuma kanjani amamojula amaningi okulawula kanye nezinhlelo kuhlelo lokusebenza olujwayelekile lweNissan. Empeleni, uhlelo lokuxhumana olujwayelekile lwebhasi lwe-CAN luhlanganisa amakhilomitha ambalwa ezintambo, izinkulungwane zamasekhethi, noxhumo olungaphezu kwenkulungwane oluhlanganisa amamojula ambalwa okulawula ndawonye. Ngalesi sizathu, kuhlala kulula futhi kubiza kakhulu ukufuna usizo lochwepheshe lapho usebenza namakhodi ahlobene nebhasi le-CAN.

Ikhodi ye-U1000 - ungayilungisa kanjani?

Konke ukuxhumana ngebhasi le-CAN kudinga umhlabathi omuhle, akukho ukuqhubeka kwesifunda esifushane, akukho ukumelana okungabangela ukwehla kwamandla kagesi, kanye nezingxenye ezinhle.

  1. Finyelela kuwo wonke ama-Bulletin Wesevisi Yezobuchwepheshe (TSB) ahlobene nekhodi U1000 nanoma imaphi amakhodi engeziwe emodeli yakho ethile kanye neqembu lenketho.
  2. Sebenzisa imanuwali yesevisi ngokuhlanganyela ne-TSB ukuze uhlonze indawo eyinkinga noma imojula.
  3. Funda indlela yokufinyelela imojuli ehlulekile.
  4. Nqamula imodyuli ukuze uyihlukanise nehhanisi kanye nesixhumi sebhasi le-CAN.
  5. Usebenzisa i-voltmeter, hlola ihhanisi lebhasi le-CAN nesixhumi ukuze uthole izikhindi noma amasekhethi avuliwe.
  6. Hlola inhlobonhlobo yezinhlelo zokusebenza zomthetho usebenzisa iyunithi yokulawula injini noma imojuli ukuze wenze izinqumo.
