Kutaya Kulumikizana Ndi Module Yoyang'anira Anti-lock Braking System (ABS)

Kodi cholakwika U0121 chimatanthauza chiyani?

Iyi ndi njira yolankhulirana yodziwika bwino yomwe imagwiritsidwa ntchito pazipangidwe zambiri zamitundu yamagalimoto. Izi zitha kuphatikizira koma sizochepera ku Mazda, Chevrolet, Dodge, VW, Ford, Jeep, GMC, ndi zina zambiri.

Nambala iyi imalumikizidwa ndi mayendedwe olumikizirana pakati pa gawo loyang'anira anti-lock braking system (ABS) ndi ma module ena oyendetsa pagalimoto.

Chingwe cholumikizirachi chimadziwika kuti Controller Area Network kulumikizana, kapena kungoyankha basi ya CAN. Popanda basi iyi ya CAN, ma module oyendetsa sangathe kulumikizana ndipo chida chanu cha scan sichitha kulumikizana ndi galimotoyo, kutengera dera lomwe likukhudzidwa.

Njira zothetsera mavuto zimatha kusiyanasiyana kutengera wopanga, mtundu wa njira yolumikizirana, kuchuluka kwa mawaya, ndi mitundu ya mawaya olumikizirana.

Zizindikiro

Zizindikiro za nambala ya injini ya U0121 itha kuphatikizira:

• Nyali Yazizindikiro Zosagwira (MIL) yaunikira
• Chizindikiro cha ABS chikuyatsa
• Chizindikiro cha TRAC chikuyatsa (kutengera wopanga)
• Chizindikiro cha ESP / ESC chikuyatsa (kutengera wopanga)

Zifukwa za zolakwika U0121

Nthawi zambiri chifukwa chokhazikitsa nambala iyi ndi:

• Tsegulani mu dera la CAN +
• Tsegulani mu basi ya CAN - dera lamagetsi
• Dera lalifupi lamphamvu mu dera lililonse la CAN
• Pafupipafupi pamtunda uliwonse wa CAN
• Nthawi zambiri - gawo lowongolera ndilolakwika

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Ngati chida chanu chojambulira chitha kupeza ma code ovuta ndipo nambala yokhayo yomwe mukukoka kuchokera ku ma module ena ndi U0121, yesani kupeza gawo la ABS. Ngati mutha kupeza ma code kuchokera ku gawo la ABS, ndiye kuti code U0121 mwina ndi yapakatikati kapena kukumbukira kukumbukira. Ngati ma code a gawo la ABS sangathe kupezeka, ndiye kuti code U0121 yokhazikitsidwa ndi ma modules ena ikugwira ntchito ndipo vuto liripo kale.

Kulephera kofala kwambiri ndiko kutaya mphamvu kapena nthaka.

Onani mafyuzi onse opereka gawo la ABS pagalimoto iyi. Fufuzani malo onse a gawo la ABS. Pezani zida zolumikizira pagalimoto ndipo onetsetsani kuti malumikizowo ndi oyera komanso otetezeka. Ngati ndi kotheka, chotsani, tengani kansalu kakang'ono ka waya ndi koloko wa soda / madzi ndikuyeretsani chilichonse, cholumikizira komanso malo omwe amalumikizana.

Ngati pali kukonza kulikonse, chotsani ma DTC pamtima ndikuwona ngati U0121 ibwerera kapena mutha kulumikizana ndi module ya ABS. Ngati palibe nambala yobwezera kapena yolumikizidwa yomwe yabwezerezedwanso, vutoli mwina ndi fuse / kulumikizana.

Khodi ikabwerera, yang'anani kulumikizana kwa basi C CAN pa galimoto yanu, makamaka cholumikizira gawo la ABS. Chotsani chingwe choyipa cha batri musanachotse cholumikizira pa gawo loyang'anira la ABS. Mukazindikira, yang'anani zowonera zolumikizira ndi zingwe. Fufuzani zokopa, scuffs, mawaya owonekera, mabala owotchera, kapena pulasitiki wosungunuka. Chotsani zolumikizira ndikuyang'anitsitsa malo (zitsulo) mkati mwa zolumikizira. Onani ngati akuwoneka owotcha kapena ali ndi utoto wobiriwira wosonyeza dzimbiri. Ngati mukufuna kuyeretsa malo, gwiritsani ntchito zotsukira zamagetsi ndi burashi ya pulasitiki pamalo aliwonse ogulitsa. Lolani kuti muumitse ndikugwiritsa ntchito mafuta a dielectric silicone pomwe malo amakhudza.

Chitani macheke ochepa awa musanayambe kulumikizanso zolumikizira ku gawo la ABS. Mudzafunika kupeza digito volt/ohmmeter (DVOM). Onetsetsani kuti muli ndi mphamvu komanso pansi pa module ya ABS. Pezani chithunzi cha mawaya ndikuzindikira komwe mphamvu yayikulu ndi zinthu zapansi zimalowetsa gawo la ABS. Lumikizaninso batire musanapitirize ndi gawo la ABS loyimitsidwa. Lumikizani chowongolera chofiira cha voltmeter pamagetsi aliwonse a B + (voltage ya batri) yomwe imalumikizidwa ndi cholumikizira cha gawo la ABS, ndi chiwongolero chakuda cha voltmeter pamalo abwino (ngati simukutsimikiza, batire imagwira ntchito nthawi zonse). Mukuwona kuwerenga kwa batri. Onetsetsani kuti muli ndi chifukwa chabwino. Lumikizani chowongolera chofiira cha voltmeter ku batri yabwino (B+) ndi chowongolera chakuda kudera lililonse lapansi. Apanso, muyenera kuwona mphamvu ya batri nthawi iliyonse mukalumikiza. Ngati sichoncho, konzani mphamvu kapena dera lapansi.

Kenako yang'anani zigawo ziwiri zoyankhulirana. Pezani CAN C+ (kapena HSCAN+) ndi CAN C- (kapena HSCAN - dera). Ndi waya wakuda wa voltmeter wolumikizidwa ku nthaka yabwino, gwirizanitsani waya wofiira ku CAN C+. Ndi kiyi yoyatsidwa ndi injini yozimitsa, muyenera kuwona pafupifupi 2.6 volts ndikusinthasintha pang'ono. Kenako gwirizanitsani waya wofiira wa voltmeter ku CAN C- dera. Muyenera kuwona pafupifupi 2.4 volts ndikusinthasintha pang'ono.

Ngati mayesero onse adutsa ndipo kulankhulana sikungatheke kapena simunathe kukonzanso DTC U0121, chinthu chokha chomwe mungachite ndikupempha thandizo kwa katswiri wodziwa zamagalimoto ophunzitsidwa bwino chifukwa izi zidzasonyeza gawo lolakwika la ABS. Ambiri mwa ma module a ABSwa amafunika kukonzedwa kapena kusinthidwa kuti akhazikitse bwino.

Zolakwika Zowonongeka

Zotsatirazi ndi zina mwazolakwitsa zomwe katswiri amatha kupanga pozindikira nambala ya U0121:

• Palibe kuwunika kwa deta yowumitsa kuti mudziwe momwe DTC idakhazikitsidwa.
• Musayang'ane zikalata zamagalimoto kuti muwonetsetse kuti nambalayo ndi yolondola osati nambala ina.
• Kugwiritsa ntchito zida zowunikira zomwe zimatanthauzira molakwika ma DTC ndi malipoti amasanthula zotsatira kwa iwo.
• Sikuti kuyezetsa konse kapena kuyesa ma paging komwe kumafunikira kuti muzindikire zida zolakwika sikuyendetsedwa. Zingakhale zosavuta kuzindikira chinthu chimodzi kapena ziwiri zolakwika, koma mayesero onse ayenera kuchitidwa kuti adziwe bwinobwino.
• Musanasinthire zigawo zilizonse kapena zigawo, nthawi zonse fufuzani kuti zikugwirizana ndi galimotoyo.

Kodi izi ndizovuta bwanji?

Khodi U0121 imatengedwa kuti ndiyowopsa. Ngati galimoto ikuwonetsa zizindikiro, iyenera kuzindikiridwa mwamsanga kuti ipewe kuwonongeka kwina ndi kuthekera kwa ngozi.

Ndi kukonza kotani komwe kungakonzeko?

M'munsimu muli njira zothetsera vutoli:

• Choyamba lembani zovuta zilizonse zomwe zingakhalepo.
• Yang'anani mawaya ndi gawo lowongolera mabuleki a ABS pogwiritsa ntchito buku lautumiki. Yang'anani mawaya kuti muwone ngati pali zizindikiro zoonekeratu za kuwonongeka monga kutha, dzimbiri, kapena kupsa. Konzani madera aliwonse owonongeka.
• Yang'anani kukana, mphamvu yowonetsera, kupitiliza, ndi chizindikiro chapansi cha makina ogwiritsira ntchito monga momwe akulangizira mu bukhu lautumiki. Ngati mupeza mtengo wopitilira muyeso, chitanipo kanthu koyenera.

Zizindikiro zogwirizana

Khodi U0121 imalumikizidwa ndipo imatha kutsagana ndi ma code awa:

P0021 , P0117 , P0220, P0732, P0457 , P0332 , U0401 ndi p2005 ndi p0358 , P0033 , P0868 ndi p0735

Mukufuna thandizo lina ndi code u0121?

Ngati mukufunabe thandizo ndi DTC U0121, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
