U0121 Ukuxhumana Okulahlekile NgeModyuli Yokulawula i-Anti-lock Braking System (ABS)

Idatha ye-DTC U0121-OBD-II

Ukuxhumana Okulahlekile Nge-Anti-lock Braking System (ABS) Control Module

Lisho ukuthini iphutha elithi U0121?

Lena ikhodi yenkinga yokuxilonga yesistimu yokuxhumana evamile esebenza ekwenziweni okuningi namamodeli ezimoto. Lokhu kungase kuhlanganise kodwa akukhawulelwe ku-Mazda, Chevrolet, Dodge, VW, Ford, Jeep, GMC, njll.

Le khodi ihlotshaniswa nesekhethi yokuxhumana phakathi kwe-anti-lock braking system (ABS) control module kanye namanye amamojula okulawula emotweni.

Lolu chungechunge lokuxhumana luvame ukubizwa ngokuthi i-Controller Area Network ngebhasi ukuxhumana noma, kalula nje, ibhasi le-CAN. Ngaphandle kwaleli bhasi le-CAN, amamojula okulawula awakwazi ukuxhumana futhi ithuluzi lakho lokuskena lingase lingakwazi ukuxhumana nemoto, kuye ngokuthi iyiphi isekethi ehilelekile.

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

Izimpawu

Izimpawu zekhodi yenjini engu-U0121 zingafaka:

• Ilambu Lenkomba Yokungasebenzi (MIL) likhanyisiwe
• Isibonisi se-ABS sivuliwe
• Isikhombi se-TRAC sivuliwe (kuya ngomkhiqizi)
• Isibonisi se-ESP / ESC sivuliwe (kuya ngomkhiqizi)

Izimbangela zephutha U0121

Imvamisa isizathu sokufaka le khodi sithi:

• Vula kusifunda se-CAN +
• Vula ebhasini le-CAN - isekethe kagesi
• Isifunda esifushane sokufaka amandla kunoma yisiphi isifunda sebhasi le-CAN
• Mfushane kuya phansi kunoma yisiphi isifunda sebhasi le-CAN
• Akuvamile - imojula yokulawula inephutha

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Uma ithuluzi lakho lokuskena lingafinyelela amakhodi ezinkinga futhi okuwukuphela kwekhodi oyikhipha kwamanye amamojula ngu-U0121, zama ukufinyelela imojula ye-ABS. Uma ukwazi ukufinyelela amakhodi kumojula ye-ABS, khona-ke ikhodi ethi U0121 iyikhodi yesikhashana noma yememori. Uma amakhodi emojula ye-ABS engafinyeleleki, ikhodi ethi U0121 esethwe ngamanye amamojuli iyasebenza futhi inkinga isivele ikhona.

Ukwehluleka okuvame kakhulu ukulahlekelwa amandla noma umhlabathi.

Bheka wonke amafuse anikezela ngemojula ye-ABS kule moto. Hlola zonke izizathu zemojuli ye-ABS. Thola izindawo okunamathiselwe kuzo phansi emotweni futhi uqiniseke ukuthi lezi zixhumanisi 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 i-DTCs enkumbulweni futhi ubone ukuthi i-U0121 iyabuya yini noma ungathinta imojula ye-ABS. Uma kungekho khodi ebuyisiwe noma ukuxhumana kubuyiswe, inkinga kungenzeka ukuthi iyinkinga ye-fuse / yokuxhuma.

Uma ikhodi ibuya, bheka ukuxhumana kwebhasi le-CAN C emotweni yakho ethile, ikakhulukazi isixhumi semojuli ye-ABS. Nqamula ikhebula yebhethri enegethivu ngaphambi kokunqamula isixhumi kumojuli yokulawula ye-ABS. Uma isitholiwe, bheka izixhumi nezintambo. Bheka imihuzuko, ama-scuffs, izintambo eziveziwe, izimpawu zokusha, noma ipulasitiki encibilikisiwe. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bheka ukuthi zibukeka zishile yini noma zine-tint eluhlaza ekhombisa ukugqwala. Uma udinga ukuhlanza amatheminali, sebenzisa okokuhlanza okuthinta ugesi kanye nebhulashi le-plastic bristle kunoma yisiphi isitolo sezingxenye. Vumela ukuthi zome futhi zigcobe i-dielectric silicone grease lapho amatheminali ethinta khona.

Yenza lokhu kuhlola okumbalwa kagesi ngaphambi kokuxhuma kabusha izixhumi kumojula ye-ABS. Uzodinga ukufinyelela ku-digital volt/ohmmeter (DVOM). Qiniseka ukuthi unamandla futhi ugxilile kumojuli ye-ABS. Finyelela kumdwebo wezintambo bese unquma ukuthi amandla amakhulu kanye nezinto ezisetshenziswa emhlabathini zifaka kuphi imojula ye-ABS. Xhuma kabusha ibhethri ngaphambi kokuqhubeka nemojuli ye-ABS ivaliwe. Xhuma intambo ebomvu ye-voltmeter ku-B+ ngayinye (i-voltage yebhethri) exhunywe kusixhumi semojuli ye-ABS, kanye nomthofu omnyama we-voltmeter endaweni enhle (uma ungaqiniseki, ukungabi nebhethri kusebenza njalo). Ubona ukufundwa kwamandla ebhethri. 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.

Uma zonke izivivinyo ziphumelela futhi ukuxhumana kungakenzeki noma awukwazanga ukusetha kabusha i-DTC U0121, into kuphela ongayenza ukufuna usizo kuchwepheshe oqeqeshiwe wezimoto njengoba lokhu kuzobonisa imojuli ye-ABS enephutha. Iningi lala mamojula e-ABS adinga ukuhlelwa noma ukulinganisa imoto ukuze iwafake ngendlela efanele.

Amaphutha avamile

Okulandelayo ngamanye amaphutha ajwayelekile uchwepheshe angawenza lapho exilonga ikhodi ethi U0121:

• Akukho ukuhlola kwedatha yozimele wokumisa ukuze kutholwe izimo lapho i-DTC yamiswa ngaphansi kwazo.
• Ungawahloli amadokhumenti emoto ukuze uqiniseke ukuthi ikhodi ilungile hhayi enye ikhodi.
• Ukusetshenziswa kwemishini yokuxilonga ehumusha kabi ama-DTC futhi ibike imiphumela yokuskena kuwo.
• Akuzona zonke izivivinyo noma ukuhlolwa kwekhasi okudingekayo ukuze kutholakale izingxenye ezinephutha akwenziwa. Kungase kube lula ukuhlonza ingxenye eyodwa noma ezimbili ezinephutha, kodwa zonke izivivinyo kufanele zenziwe ukuze kutholakale ukuxilongwa okunembile.
• Ngaphambi kokushintsha noma yiziphi izingxenye noma izingxenye, hlola njalo ukuhambisana kwazo nemoto.

Kubi kangakanani lokhu?

Ikhodi U0121 ithathwa njengebucayi. Uma imoto ibonisa izimpawu, kufanele ihlolwe ngokushesha ngangokunokwenzeka ukuze kugwenywe omunye umonakalo kanye nethuba lengozi.

Ikuphi ukulungisa okungalungisa ikhodi?

Ngezansi izixazululo ezingalungisa le nkinga:

• Qala ngokubhala phansi noma imaphi amakhodi ezinkinga okungenzeka akhona.
• Hlola indawo yemojula yokulawula izintambo kanye ne-ABS usebenzisa imanuwali yesevisi. Hlola izintambo ukuze uthole izimpawu zomonakalo ezisobala njengokuguga, ukugqwala, noma ukusha. Lungisa noma yiziphi izindawo ezilimele.
• Hlola ukumelana, ireferensi kagesi, ukuqhubeka, nesignali yaphansi yehhanisi lesistimu njengoba kuyalelwe kumanuwali wesevisi. Uma uthola inani elingaphandle kwebanga, thatha isinyathelo esifanele sokulungisa.

Udinga usizo olwengeziwe ngekhodi yakho ye-u0121?

Uma usadinga usizo nge-DTC U0121, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
