Momwe mungayang'anire sensor ya ABS ndi multimeter
Zamkatimu
Masensa a Anti-Lock Braking System (ABS) ndi zigawo zamagalimoto amakono omwe amalumikizana ndi ECU ndikuwunika kuchuluka kwa braking mukayesa kuyimitsa galimoto yanu.
Izi ndi masensa omwe amamangiriridwa ku mawilo kudzera pa chingwe chowongolera chomwe chimayang'anira liwiro lomwe mawilo akuzungulira komanso amagwiritsa ntchito deta iyi kuti adziwe ngati mawilo akutsekedwa.
Brake yomwe imayikidwa kudzera pa ABS imathamanganso kuposa handbrake. Izi zikutanthauza kuti ndizothandiza pazovuta kwambiri, monga mukamayendetsa m'misewu yonyowa kapena youndana.
Vuto lokhala ndi sensa limatanthauza chiwopsezo chowonekera m'moyo wanu, ndipo chowunikira cha ABS kapena chowongolera chowongolera chimafunikira chisamaliro chachangu.
Momwe mungadziwire sensa yamavuto?
Wotsogolera wathu akuwuzani zonse zomwe muyenera kudziwa za momwe mungayesere sensor ya ABS.
Tiyeni tiyambe.
Zida Zofunikira Kuti Mufufuze Sensor ya ABS
Pa mayesero onse omwe atchulidwa apa, mudzafunika
- multimeter
- Mndandanda wa makiyi
- Jack
- OBD Scan Chida
Multimeter imatithandiza kuchita mitundu yosiyanasiyana yowunikira ma sensor ndipo ndiye chida chofunikira kwambiri.
Momwe mungayang'anire sensor ya ABS ndi multimeter
Kwezani galimoto ndi jekeseni wagalimoto, chotsani chingwe cha sensa ya ABS, ikani multimeter ku 20K ohm range, ndikuyika zofufuza pazigawo za sensa. Mukuyembekeza kuwerenga bwino pakati pa 800 ndi 2000 ohms ngati ABS ili bwino.
Tidzayang'ana pa kuyesaku ndikukuwonetsaninso momwe mungadziwire vutolo poyang'ana kuwerengera kwa AC voltage sensor.
- Kukwera galimoto
Kuti mutetezeke, mumayika ma transmissions agalimoto mu park mode ndikuyatsanso brake yadzidzidzi kuti isasunthe mukakhala pansi pake.
Tsopano, kuti mukhale ndi mwayi wopeza sensa kuti muzindikire bwino pa izo, muyeneranso kukweza galimoto kumene sensor ili.
Kutengera ndi galimoto yanu, sensa nthawi zambiri imakhala kuseri kwa magudumu amodzi, koma mutha kuloza buku la eni galimoto yanu kuti lidziwe komwe ili.
Mukufunanso kudziwa momwe sensor ya ABS imawonekera pagalimoto yanu kuti musasokoneze sensa ndi masensa ena.
Ikani mphasa pansi pa galimoto kuti zovala zanu zikhale zaukhondo pamene mukuyesa izi.
- Khazikitsani ma multimeter kukhala 20 kΩ osiyanasiyana
Khazikitsani mita pamalo a "Ohm", owonetsedwa ndi chizindikiro cha omega (Ω).
Mudzawona gulu la manambala mu gawo la ohm la mita lomwe limayimira kuchuluka kwa kuyeza (200, 2k, 20k, 200k, 2m ndi 200m).
Kukana koyembekezeka kwa sensor ya ABS kumafuna kuti muyike mita mumtundu wa 20 kΩ kuti muwerenge koyenera kwambiri.
- Chotsani chingwe cha ABS
Tsopano mumadula anti-lock brake system kuchokera ku sensor chingwe kuti muwonetse ma terminals kuti muyesedwe.
Apa mumadula mophweka komanso mwaukhondo zingwe zamawaya pamalo awo olumikizirana ndikusunthira chidwi chanu pazingwe zamawaya kuchokera kumbali ya gudumu.
- Ikani ma probe pa ma terminals a ABS
Chifukwa polarity zilibe kanthu poyezera ma ohms, mumayika ma probe a mita pamtundu uliwonse wa sensa.
- Voterani zotsatira
Tsopano mumayang'ana kuwerenga kwa mita. Masensa a ABS akuyembekezeka kukhala ndi kukana kwa 800 ohms mpaka 2000 ohms.
Poyang'ana chitsanzo cha sensa ya galimoto yanu, mumazindikira mikhalidwe yoyenera kuti muwone ngati mukupeza mtengo woyenera kapena ayi.
Chifukwa mita ili mumtundu wa 20 kΩ, idzawonetsa mtengo wokhazikika pakati pa 0.8 ndi 2.0 ngati sensor ili bwino.
Mtengo wakunja kwamtunduwu kapena kusinthasintha kumatanthauza kuti sensa ili ndi vuto ndipo ikufunika kusinthidwa.
Ngati mumapezanso "OL" kapena "1" kuwerenga, izi zikutanthauza kuti sensa ili ndi kukana kwakanthawi kochepa, kotseguka, kapena kopitilira muyeso ndipo muyenera kuyisintha.
Kuyesa kwamagetsi kwa ABS AC
Kuyang'ana mphamvu ya sensor ya ABS kumatithandiza kudziwa ngati sensor ikugwira ntchito moyenera.
Galimotoyo ili mu park mode, brake yadzidzidzi idayikidwa, ndikukweza galimoto, chitani zotsatirazi.
- Khazikitsani ma multimeter kukhala 200VAC voltage range
Mphamvu ya AC imayimiridwa pa multimeter ngati "V~" kapena "VAC" ndipo nthawi zambiri imakhala ndi magawo awiri; 200V ~ ndi 600V ~.
Khazikitsani ma multimeter kukhala 200 V ~ kuti mupeze zotsatira zoyenera kwambiri.
- Ikani ma probe pa ma terminals a ABS
Monga momwe zimakhalira ndi mayeso okana, mumalumikiza zoyeserera ku ma terminal a ABS.
Mwamwayi, ma terminals a ABS sanakhazikitsidwe, kotero mutha kungolumikiza mawaya kumalo aliwonse osadandaula za kuwerenga kolakwika.
- Chipinda chozungulira
Tsopano, kuti muyese kayendedwe ka galimoto, mumazungulira gudumu lomwe ABS imalumikizidwa. Izi zimapanga magetsi, ndipo kuchuluka kwa volt komwe kumapangidwa kumadalira liwiro la gudumu.
Mukufuna kuwonetsetsa kuti mukuzungulira gudumu pa liwiro lokhazikika kuti mupeze mtengo wokhazikika kuchokera ku counter.
Kwa mayeso athu, mumapanga kusintha masekondi awiri aliwonse. Mwanjira imeneyi simusangalala ndi kupota kwa gudumu.
- Onani ma multimeter
Pakadali pano, multimeter ikuyembekezeka kuwonetsa mtengo wamagetsi. Pa liwiro lathu lozungulira, mphamvu yofananira ya AC ndi pafupifupi 0.25 V (250 millivolts).
Ngati simukupeza kuwerenga kwa mita, yesani kulumikiza cholumikizira cha sensor komwe chimalowa mu gudumu. Ngati simuwerengabe mukamayesa ma multimeter anu, ndiye kuti ABS yalephera ndipo ikufunika kusinthidwa.
Kuperewera kwa voteji kapena mtengo wolakwika wa voteji kungayambitsidwenso ndi vuto la gudumu lokha. Kuti muzindikire izi, sinthani ABS ndi sensor yatsopano ndikuyesanso kuyesa kwamagetsi komweko.
Ngati simukupezabe kuwerengera koyenera kwamagetsi, vuto liri ndi gudumu ndipo muyenera kuyisintha.
Kuzindikira ndi OBD Scanner
Chojambulira cha OBD chimakupatsirani njira yosavuta yodziwira zovuta ndi sensa yanu ya ABS, ngakhale sizolondola monga kuyesa kwa ma multimeter.
Mumayika scanner mugawo la owerenga pansi pa dash ndikuyang'ana ma code olakwika okhudzana ndi ABS.
Makhodi onse olakwika kuyambira ndi chilembo "C" akuwonetsa vuto ndi sensa. Mwachitsanzo, khodi yolakwika C0060 ikuwonetsa vuto lakumanzere kwa ABS ndi C0070 ikuwonetsa vuto ndi ABS yakumanja yakumanja.
Onani mndandanda wathunthu wamakhodi a ABS ndi matanthauzo ake kuti mudziwe zomwe mungayembekezere.
Pomaliza
Sensa ya ABS ndi gawo losavuta kuyesa komanso imaperekanso njira zingapo zodziwira zovuta zamagalimoto athu.
Komabe, ndi mayeso aliwonse omwe mukufuna kuchita, onetsetsani kuti mwatsata njira zodzitetezera ndikuyika ma multimeter anu pamlingo woyenera kuti mupeze zotsatira zolondola.
Monga tafotokozera m'nkhani yathu, kumbukirani kuti chitetezo chanu pamsewu chimadalira kwambiri momwe ABS yanu imagwirira ntchito, choncho chigawo chilichonse chosokonekera chiyenera kusinthidwa mwamsanga galimotoyo isanayambe kugwira ntchito.
Mafunso ofunsidwa kawirikawiri
Kodi sensor ya ABS iyenera kukhala ndi ma ohm angati?
Sensa yabwino ya ABS ikuyembekezeka kugwira pakati pa 800 ohms ndi 200 ohms kukana kutengera mtundu wagalimoto kapena sensor. Mtengo wa kunja kwa izi umatanthauza dera lalifupi kapena kukana kosakwanira.
Kodi ndingadziwe bwanji ngati sensa yanga ya ABS ndiyoyipa?
Sensa yoyipa ya ABS imawonetsa zizindikiro monga ABS kapena kuwala kowongolera pa dashboard yomwe ikubwera, galimoto imatenga nthawi yayitali kuti iyime, kapena kusakhazikika kowopsa ikamanga mabuleki kunyowa kapena kuzizira.
