Yuav ua li cas txheeb xyuas ABS sensor nrog multimeter
Txheem
Anti-Lock Braking System (ABS) sensors yog cov khoom siv hauv cov tsheb niaj hnub uas sib txuas lus nrog ECU thiab saib xyuas tus nqi nres thaum koj sim nres koj lub tsheb.
Cov no yog cov sensors txuas rau lub log ntawm cov hlua khi uas saib xyuas qhov ceev ntawm lub log tig thiab tseem siv cov ntaub ntawv no los txiav txim seb lub log puas raug kaw.
Lub nres siv los ntawm ABS kuj tseem nrawm dua li tus brake. Qhov no txhais tau tias lawv muaj txiaj ntsig zoo hauv cov xwm txheej hnyav, xws li thaum koj tsav tsheb ntawm txoj kev ntub lossis dej khov.
Ib qho teeb meem nrog lub sensor txhais tau tias muaj kev phom sij meej rau koj lub neej, thiab lub teeb pom kev ntawm ABS lossis traction tswj yuav tsum tau ceev faj heev.
Yuav kuaj xyuas lub sensor li cas rau cov teeb meem?
Peb phau ntawv qhia yuav qhia koj txhua yam koj xav paub txog yuav ua li cas kuaj lub ABS sensor.
Cia peb pib.
Cov cuab yeej yuav tsum tau kuaj xyuas ABS Sensor
Rau txhua qhov kev xeem uas tau hais los saum no, koj yuav xav tau
- multimeter
- Ib txheej ntawm cov yuam sij
- Nkaus
- OBD Scan Tool
Lub multimeter pab peb ua ntau hom kev kuaj mob sensor thiab yog li cov cuab yeej tseem ceeb tshaj plaws.
Yuav ua li cas txheeb xyuas ABS sensor nrog multimeter
Tsa lub tsheb nrog lub tsheb jack, disconnect ABS sensor cable, teem lub multimeter mus rau 20K ohm ntau yam, thiab tso cov probes ntawm lub sensor terminals. Koj cia siab tias yuav tau txais kev nyeem ntawv zoo ntawm 800 thiab 2000 ohms yog tias ABS zoo.
Peb yuav delve rau hauv cov txheej txheem xeem no thiab tseem qhia koj yuav ua li cas kuaj tau qhov teeb meem los ntawm kev txheeb xyuas cov kev nyeem ntawm AC voltage sensor.
- Nias lub tsheb
Rau kev nyab xeeb, koj muab lub tsheb kis mus rau hauv hom chaw nres tsheb thiab tseem qhib lub nres thaum muaj xwm ceev kom nws tsis txav thaum koj nyob hauv qab.
Tam sim no, txhawm rau nkag mus rau lub sensor rau kev kuaj mob yooj yim ntawm nws, koj kuj yuav tsum tau tsa lub tsheb qhov twg lub sensor nyob.
Nyob ntawm koj lub tsheb, lub sensor feem ntau nyob tom qab ib qho ntawm cov log tsheb, tab sis koj tuaj yeem xa mus rau koj tus tswv tsheb phau ntawv qhia rau nws qhov chaw nyob.
Koj kuj xav paub seb ABS sensor zoo li cas ntawm koj lub tsheb yog li koj tsis txhob cuam tshuam lub sensor nrog lwm cov sensors.
Muab ib daim lev tso rau hauv qab lub tsheb kom koj cov khaub ncaws huv si thaum koj khiav cov kev xeem no.
- Teem lub multimeter rau 20 kΩ ntau
Teem lub 'meter' mus rau "Ohm", qhia los ntawm lub cim omega (Ω).
Koj yuav pom ib pawg ntawm cov lej nyob rau hauv ohm seem ntawm lub 'meter' uas sawv cev rau qhov ntsuas ntau yam (200, 2k, 20k, 200k, 2m thiab 200m).
Qhov kev cia siab ua haujlwm ntawm ABS sensor xav kom koj tso lub ntsuas hluav taws xob hauv 20 kΩ ntau kom tau txais kev nyeem ntawv zoo tshaj plaws.
- Tshem tawm ABS cable
Tam sim no koj disconnect lub anti-lock nres system los ntawm lub sensor cable kom nthuav tawm cov terminals rau kev sim.
Ntawm no koj yooj yim thiab zoo nkauj disconnect cov hlua hlua ntawm lawv cov ntsiab lus sib txuas thiab txav koj cov xim mus rau cov hlua hlua ntawm sab ntawm lub log.
- Muab cov kev sojntsuam rau ntawm ABS terminals
Vim tias polarity tsis muaj teeb meem thaum ntsuas ohms, koj tso lub ntsuas ntsuas ntawm ob qho ntawm lub ntsuas hluav taws xob.
- Ntsuas cov txiaj ntsig
Tam sim no koj kos lub ntsuas ntsuas. ABS sensors yuav tsum muaj qhov tsis kam ntawm 800 ohms txog 2000 ohms.
Los ntawm kev saib koj lub tsheb tus qauv sensor, koj txiav txim siab qhov tseeb cov yam ntxwv los ntsuas seb koj puas tau txais tus nqi tsim nyog lossis tsis yog.
Vim hais tias lub 'meter' yog nyob rau hauv 20 kΩ ntau, nws yuav qhia ib tug tas li tus nqi ntawm 0.8 thiab 2.0 yog hais tias tus sensor nyob rau hauv zoo.
Tus nqi sab nraud qhov no lossis tus nqi hloov pauv txhais tau hais tias lub sensor puas lawm thiab yuav tsum tau hloov.
Yog tias koj tseem tau txais "OL" lossis "1" nyeem ntawv, qhov no txhais tau hais tias lub sensor muaj luv luv, qhib, lossis dhau qhov kev tiv thaiv hauv cov hlua khi thiab koj yuav tsum tau hloov nws.
ABS AC voltage test
Kev kuaj xyuas ABS sensor voltage pab peb paub seb lub sensor puas ua haujlwm zoo hauv kev siv tiag tiag.
Nrog lub tsheb nyob rau hauv hom chaw nres tsheb, siv lub nres thaum muaj xwm ceev, thiab lub tsheb tsa, ua cov kauj ruam hauv qab no.
- Teem multimeter rau 200VAC voltage ntau
AC voltage yog sawv cev rau ntawm lub multimeter li "V ~" lossis "VAC" thiab feem ntau muaj ob yam; 200V ~ 600V ~ .
Teem lub multimeter rau 200 V ~ kom tau txais cov txiaj ntsig zoo tshaj plaws.
- Muab cov kev sojntsuam rau ntawm ABS terminals
Ib yam li nrog qhov kev xeem tsis kam, koj txuas qhov kev xeem ua rau ABS terminals.
Hmoov zoo, ABS terminals tsis polarized, yog li koj tuaj yeem yooj yim ntsaws cov xov hlau rau hauv ib qho ntawm cov terminals yam tsis muaj kev txhawj xeeb txog kev nyeem tsis raug.
- Rotation log hub
Tam sim no, txhawm rau simulate lub zog ntawm lub tsheb, koj tig lub log hub uas ABS txuas nrog. Qhov no generates ib tug voltage, thiab tus nqi ntawm volt generated nyob ntawm qhov ceev ntawm lub log.
Koj xav kom koj tig lub log ntawm qhov nrawm kom tau txais tus nqi tas li los ntawm lub txee.
Rau peb qhov kev sim, koj ua ib lub kiv puag ncig txhua ob vib nas this. Txoj kev no koj tsis tau txais kev zoo siab txog kev sib tw ntawm lub log.
- Tshawb xyuas multimeter
Nyob rau hauv no hais txog, lub multimeter yuav tsum tso saib tus nqi voltage. Rau peb qhov kev sib hloov ceev, qhov sib thooj AC voltage yog li 0.25 V (250 millivolts).
Yog tias koj tsis tau txais ib lub 'meter' nyeem ntawv, sim ntsaws lub ntsuas hluav taws xob mus rau qhov twg nws nkag mus rau lub log hub. Yog tias koj tseem tsis tau txais kev nyeem ntawv thaum koj sim koj lub multimeter, ces ABS tau ua tsis tiav thiab yuav tsum tau hloov.
Qhov tsis muaj qhov hluav taws xob lossis qhov tsis raug ntawm qhov hluav taws xob kuj tuaj yeem tshwm sim los ntawm qhov teeb meem ntawm lub log hub nws tus kheej. Txhawm rau kuaj xyuas qhov no, hloov ABS nrog lub sensor tshiab thiab khiav qhov ntsuas qhov tseeb dua.
Yog tias koj tseem tsis tau txais kev nyeem ntawv voltage, qhov teeb meem yog nrog lub log hub thiab koj yuav tsum tau hloov nws.
Kev kuaj mob nrog OBD Scanner
Lub OBD scanner muab koj cov kev daws teeb meem yooj yim rau kev txheeb xyuas cov teeb meem nrog koj lub ABS sensor, txawm hais tias lawv tsis raug raws li kev ntsuas ntsuas ntau.
Koj ntxig ib lub scanner rau hauv lub qhov nyeem ntawv nyob rau hauv lub dash thiab nrhiav ABS cov lej yuam kev.
Txhua tus lej yuam kev pib nrog tsab ntawv "C" qhia tias muaj teeb meem nrog lub sensor. Piv txwv li, qhov yuam kev code C0060 qhia tias muaj teeb meem nrog rau sab laug ABS thiab C0070 qhia tias muaj teeb meem nrog rau sab xis ABS.
Xa mus rau daim ntawv teev tag nrho ntawm ABS cov lej yuam kev thiab lawv lub ntsiab lus kom paub seb yuav xav li cas.
xaus
ABS sensor yog ib qho yooj yim haum rau kev sim thiab tseem muaj ntau txoj hauv kev los kuaj xyuas cov teeb meem hauv peb lub tsheb.
Txawm li cas los xij, nrog rau txhua qhov kev sim koj xav ua, xyuas kom tseeb tias koj siv cov kev ceev faj txog kev nyab xeeb thiab teeb tsa koj lub multimeter mus rau qhov tseeb kom tau txais cov txiaj ntsig raug.
Raws li tau hais hauv peb tsab xov xwm, nco ntsoov tias koj txoj kev nyab xeeb ntawm txoj kev yog nyob ntawm qhov ua tau zoo ntawm koj lub ABS, yog li txhua yam khoom siv tsis raug yuav tsum tau hloov tam sim ua ntej lub tsheb yuav tsum tau ua haujlwm.
Cov lus nug nquag nug
Muaj pes tsawg ohms yuav tsum muaj ABS sensor?
ABS zoo sensor yuav tsum tuav ntawm 800 ohms thiab 200 ohms kuj nyob ntawm lub tsheb lossis tus qauv sensor. Tus nqi sab nraud ntawm qhov no txhais tau hais tias luv luv Circuit Court lossis tsis txaus tiv thaiv.
Kuv yuav ua li cas thiaj paub yog tias kuv ABS sensor tsis zoo?
ABS tsis zoo sensor qhia pom cov cim xws li ABS lossis traction tswj lub teeb ntawm lub dashboard los, lub tsheb siv sijhawm ntev los nres, lossis tsis muaj kev phom sij txaus ntshai thaum nres hauv ntub lossis dej khov.
