Yakarasika Kutaurirana NeAnti-kukiya Braking System (ABS) Kudzora Module

Ko kukanganisa U0121 kunorevei?

Iyi generic kutaurirana sisitimu yekunetseka kodhi inoshanda kune akawanda anogadzira uye mamodheru emota. Izvi zvinogona kusanganisira asi hazvirevi kuMazda, Chevrolet, Dodge, VW, Ford, Jeep, GMC, nezvimwe.

Iyi kodhi inosanganisirwa neyekutaurirana wedunhu pakati peanti-kukiya braking system (ABS) module yekudzora uye mamwe ma module ekudzora pamotokari.

Iyi cheni yekutaurirana inowanzo kunzi seController Area Network kutaurirana, kana kungoita bhazi reCAN. Pasina iri bhazi reCAN, ma module ekudzora haakwanise kutaurirana uye chishandiso chako chekutarisa chingatadze kutaurirana nemotokari, zvinoenderana nedunhu ripi rinobatanidzwa.

Matanho ekugadzirisa matambudziko anogona kusiyana zvichienderana nemugadziri, mhando yematauriro, huwandu hwewaya, uye mavara ewaya muchirongwa chekutaurirana.

Zviratidzo

Zviratidzo zveU0121 injini kodhi inogona kusanganisira:

• Chisina kushanda Chiratidzo Lamp (MIL) yakavhenekerwa
• ABS chiratidzo chiri
• TRAC chiratidzo chiri (zvinoenderana nemugadziri)
• ESP / ESC chiratidzo chiri (zvichienderana nemugadziri)

Zvikonzero zvekukanganisa U0121

Kazhinji chikonzero chekuisa iyi kodhi ndechekuti:

• Vhura muCAN + bhazi redunhu
• Vhura muCAN bhazi - dunhu remagetsi
• Ipfupi redunhu kune simba mune chero CAN bhazi redunhu
• Ipfupi kusvika pasi mune chero CAN bhazi redunhu
• Kashoma - iyo module yekudzora haina kunaka

Kuongorora uye kugadzirisa maitiro

Nzvimbo yakanaka yekutanga nguva dzose yekutarisa technical Service Bulletins (TSB) kune yako chaiyo mota. Dambudziko rako rinogona kunge riri nyaya inozivikanwa neyakagadzirwa gadziriso-yakaburitswa gadziriso uye inogona kukusevha nguva nemari panguva yekugadzirisa matambudziko.

Kana chishandiso chako chekuongorora chichikwanisa kuwana makodhi ematambudziko uye kodhi chete yauri kudhonza kubva kune mamwe mamodule ndiU0121, edza kuwana iyo ABS module. Kana iwe uchikwanisa kuwana macode kubva kuABS module, ipapo kodhi U0121 ingave iri yepakati kana yekurangarira kodhi. Kana iyo macode eiyo ABS module isingagone kuwanikwa, ipapo kodhi U0121 yakaiswa nemamwe ma module inoshanda uye dambudziko ratovepo.

Chinonyanya kukundikana kurasikirwa kwesimba kana pasi.

Tarisa fuses dzese dzinopa iyo ABS module pane ino mota. Tarisa zvese zvikonzero zveiyo module yeABS. Tsvaga nzvimbo dzekubatanidza pamotokari uye ita shuwa kuti kubatana uku kwakachena uye kwakachengeteka. Kana zvichidikanwa, bvisa, tora tambo diki yesimbi bristle uye soda / mhinduro yemvura uye chenesa imwe neimwe, zvese zvinobatanidza uye nenzvimbo painobatana.

Kana paine chero gadziriso dzakaitwa, bvisa iyo DTCs kubva mundangariro uye uone kana U0121 ichidzoka kana iwe unogona kubata module yeABS. Kana pasina kodhi inodzoka kana kubatana kwadzoreredzwa, dambudziko iri rinogona kunge riri fuse / yekubatanidza nyaya.

Kana iyo kodhi ikadzoka, tsvaga UNANGANO yebhazi kubatanidza pane yako chaiyo mota, kunyanya iyo ABS module yekubatanidza. Dzinga tambo yakashata yebheteri usati wabvisa chinongedzo pane module yeABS yekudzora. Kana uchinge waonekwa, zviongorore ongorora zvinobatanidza uye wiring. Tarisa mitsetse, scuffs, waya dzakafumurwa, kupisa maki, kana plastiki yakanyungudika. Bvisa ma connector uye nyatsoongorora zviteshi (simbi zvikamu) mukati mezvinobatanidza. Tarisa uone kana vachitaridzika kunge akatsva kana vane tint yegirini inoratidza kuora. Kana iwe uchida kuchenesa zviteshi, shandisa yemagetsi yekubata yakachenesa uye purasitiki bristle bhurashi pane chero zvikamu zvechitoro. Rega kuomesa uye kuisa dielectric silicone girizi panobata zviteshi.

Ita mashoma aya macheki emagetsi usati wabatanidzazve majoini kuABS module. Iwe unozoda kupinda kune dijitari volt/ohmmeter (DVOM). Ita shuwa kuti une simba uye pasi pane ABS module. Svika iyo wiring dhayagiramu uye uone uko iyo huru simba uye yepasi zvinhu zvinopinda iyo ABS module. Batanidzazve bhatiri usati waenderera mberi neABS module yakadzimwa. Batanidza iyo dzvuku lead yevoltmeter kune yega yega B + (bhatiri voltage) magetsi akavharirwa muABS module yekubatanidza, uye mutema unotungamira wevoltmeter panzvimbo yakanaka (kana isina chokwadi, bhatiri negative rinogara richishanda). Iwe unoona bhatiri voltage kuverenga. Iva nechokwadi chokuti une chikonzero chakanaka. Batanidza iyo tsvuku inotungamira yevoltmeter kune bhatiri yakanaka (B +) uye dema inotungamira kune imwe neimwe yepasi dunhu. Zvekare, iwe unofanirwa kuona iyo bhatiri voltage pese paunobatanidza. Kana zvisina kudaro, gadzirisa simba kana pasi redunhu.

Zvadaro tarisa matunhu maviri ekutaurirana. Tsvaga CAN C+ (kana HSCAN+) uye CAN C- (kana HSCAN - dunhu). Newaya nhema yevoltmeter yakabatana nevhu rakanaka, batanidza waya tsvuku kuCAN C+. Nekiyi yakavhurwa uye injini yakadzimwa, iwe unofanirwa kuona nezve 2.6 volts ine zvishoma kushanduka. Zvadaro batanidza tambo tsvuku ye voltmeter kuCAN C- circuit. Iwe unofanirwa kuona nezve 2.4 volts ine zvishoma kushanduka.

Kana bvunzo dzese dzakapfuura uye kutaurirana kuchiri kusingagoneki kana kuti hauna kukwanisa kuseta patsva DTC U0121, chinhu choga chaunogona kuita kutsvaga rubatsiro kubva kune akadzidzira mota diagnostician sezvo izvi zvichiratidza kukanganisa ABS module. Mazhinji eaya maABS mamodule anoda kurongerwa kana kuverengerwa mota kuti aiise nemazvo.

Zvikanganiso Zvakajairika

Zvinotevera ndezvimwe zvinowanzoitika zvikanganiso zvinogona kuitwa nenyanzvi pakuongorora kodhi U0121:

• Hapana cheki cheki data yechando kuti uone mamiriro akaiswa DTC.
• Usatarise magwaro emotokari kuti uone kuti kodhi ndeyechokwadi uye kwete imwe kodhi.
• Kushandiswa kwemidziyo yekuongorora inodudzira zvisizvo maDTC uye mishumo yekuongorora mhinduro kwavari.
• Haasi ese maedzo kana mapeji bvunzo anodiwa kuti aone zvisizvo zvikamu hazviitwe. Zvinogona kunge zviri nyore kuziva chinhu chimwe kana zviviri zvakakanganisika, asi bvunzo dzese dzinofanira kuitwa kuitira kuti pave neruzivo rwakakwana.
• Usati watsiva chero zvikamu kana zvikamu, gara uchitarisa kuenderana kwavo nemotokari.

Izvi zvakakomba sei?

Code U0121 inoonekwa seyakakomba. Kana motokari ichiratidza zviratidzo, inofanira kuonekwa nokukurumidza sezvinobvira kudzivirira imwe kukuvara uye mukana wetsaona.

Ndeipi kugadzirisa inogona kugadzirisa kodhi?

Pazasi pane mhinduro dzinogona kugadzirisa dambudziko iri:

• Tanga wanyora pasi macode ematambudziko angave aripo.
• Tarisa iyo wiring uye ABS brake control module nzvimbo uchishandisa bhuku rebasa. Wongorora wiring kuona zviratidzo zviri pachena zvekukuvadzwa sekupfeka, ngura, kana kutsva. Gadzirisa chero nzvimbo dzakakuvadzwa.
• Tarisa kupokana, referensi voltage, kuenderera, uye chiratidzo chepasi cheiyo system harness sezvakarairwa mubhuku rebasa. Kana iwe ukawana kukosha kunze kwehuwandu, tora danho rakakodzera rekugadzirisa.
