ABS (anti-lock brake sensor) yog lub tachometer uas ntsuas lub log ceev. Nws mam li xa cov xam RPM mus rau Cav Tswj Module (ECM). ABS tseem hu ua log ceev sensor lossis ABS braking sensor. Txhua lub log ntawm lub tsheb muaj nws tus kheej ceev ntawm kev sib hloov, ABS sensor captures cov ntsuas ceev.

Tom qab tau txais cov ntawv ceeb toom ceev, ECM txiav txim lub xeev xauv rau txhua lub log. Sudden screeching thaum braking yog tshwm sim los ntawm ECM xauv.

Yog tias koj lub tsheb ABS ua haujlwm tsis zoo, koj tuaj yeem poob hluav taws xob ruaj khov thiab tswj kev sib tw. Yog li, nws yog qhov txaus ntshai rau tsav tsheb yam tsis paub txog qhov xwm txheej ntawm ABS sensor.

Txheeb xyuas ABS sensor yog tias qhov taw qhia traction thiab sensor teeb rau ntawm lub tsheb dashboard.

Feem ntau, txhawm rau kuaj lub ABS sensor, koj yuav tsum tau nruab multimeter ua rau ntawm cov khoom siv hluav taws xob. Tom qab ntawd koj yuav tsum tau tig lub tsheb lub log kom tau txais kev nyeem ntawv voltage. Yog tias tsis muaj kev nyeem ntawv, ces koj ABS sensor yog qhib lossis tuag.

Kuv yuav mus rau hauv ntau yam ntxiv hauv peb tsab xov xwm hauv qab no.

ABS sensors yog cov feem ntau siv sensors hauv tsheb. Nyob rau hauv lub tshiab nres system, ABS nyob rau hauv lub log hub. Nyob rau hauv ib txwm nres system, nws yog nyob rau sab nraum lub log hub - nyob rau hauv lub steering knuckle. Nws txuas nrog lub nplhaib iav mounted ntawm lub rotor tawg. (1)

Thaum twg los xyuas ABS Sensor

Cov sensors thiab cov traction tswj qhov teeb pom kev thaum lub ABS sensor pom qhov ua haujlwm tsis zoo. Koj yuav tsum saib xyuas cov ntsuas ntsuas qhov tsis ua haujlwm ntawm lub dashboard thaum tsav tsheb. Lub teeb traction yog yooj yim nyob ntawm lub dashboard. (2)

Dab tsi koj yuav tsum muaj thaum kuaj xyuas ABS sensor

Cov multimeter
Clamps (yeem, koj tsuas yog siv sensors)
Cov log tsheb
ABS cov khoom siv nyeem ntawv los pab koj nyeem cov lej ABS thiab paub qhov twg yuav tsum tau hloov
Ciaj ntswj
Cov ntaub pua plag pem teb
Nres installation cov cuab yeej
Ramps
Them nyiaj

Kuv nyiam digital multimeters vim tias lawv tsuas yog tso saib cov txiaj ntsig lossis kev nyeem ntawm qhov screen. Analog siv cov pointers, yog li koj yuav tsum tau ua qee qhov kev suav.

Yuav Ua Li Cas Ntsuas ABS Sensor: Tau Txais Kev Nyeem Ntawv

Lub multimeter muaj peb qhov tseem ceeb, uas yog cov zaub, xaiv cov pob qhov rooj, thiab cov chaw nres nkoj. Cov zaub feem ntau yuav qhia 3 tus lej thiab cov txiaj ntsig tsis zoo kuj tseem tuaj yeem pom.

Tig lub pob qhov rooj xaiv qhov chaw koj xav ntsuas. Nws tuaj yeem yog tam sim no, voltage lossis tsis kam.

Lub multimeter muaj 2 probes txuas nrog nws cov chaw nres nkoj sau npe COM thiab MAV.

COM feem ntau yog dub thiab txuas nrog hauv av hauv Circuit Court.

MAV tiv thaiv kev sojntsuam tuaj yeem yog liab thiab txuas nrog kev nyeem tam sim no.

Ua raws li cov no Cov kauj ruam yooj yim los ntsuas tag nrho ABS sensors nrog multimeter. Nco ntsoov xyuas phau ntawv qhia seb muaj pes tsawg lub log ABS sensor nyob thiab xyuas tag nrho cov sensors.

Ua tib zoo saib rau lawv tus qauv tus nqi hauv Ohms.

Nov yog cov kauj ruam:

Chaw nres tsheb koj lub tsheb thiab xyuas kom cov kis tau tus mob nyob hauv Park lossis nruab nrab. ua ntej tua lub cav. Tom qab ntawd teem lub brakes thaum muaj xwm ceev.
Siv lub jack tsa lub log ntawm ib sab ntawm lub sensor koj xav sim. Ua ntej ntawd, nws yog qhov zoo dua los nthuav cov ntaub pua plag rau hauv pem teb hauv qab lub tshuab, uas koj tuaj yeem pw, thiab nws yog qhov yooj yim rau kev ua haujlwm kho. Tsis txhob hnov qab hnav cov iav tiv thaiv.
Tshem tawm ABS sensor los ntawm kev sib txuas ntawm cov xov hlau los ntawm kev nyab xeeb tshem nws lub hau. Tom qab ntawd ntxuav nws nrog lub tshuab nqus tsev ntxhua khaub ncaws (lub sensor yog canister zoo li tus thiab muaj cov xov hlau txuas).
Teem lub multimeter rau ohms. Yooj yim tab sis khov kho kho lub pob qhov taw tes rau qhov chaw ohm. Ohm los yog tsis kam yog denoted los ntawm lub cim "Ohm".
Teem lub multimeter kom pom zero los ntawm tsis tu ncua tig lub xoom hloov pob qhov rooj.
Muab cov xov hlau sojntsuam rau ntawm ABS sensor hu. Txij li qhov kev tiv thaiv tsis yog kev taw qhia, nws tsis muaj teeb meem qhov twg koj tso rau txhua qhov kev sojntsuam. Tab sis cia lawv kom deb li deb tau kom tau txais kev nyeem ntawv zoo. Tos kom tau txais tus nqi pom zoo.
Ua tib zoo mloog cov nyeem Ohm. Muab piv rau koj lub sensor tus qauv ohm tus nqi ntawm phau ntawv. Qhov sib txawv yuav tsum tsawg dua 10%. Txwv tsis pub, koj yuav tsum hloov ABS sensor.

Xwb, koj tuaj yeem teeb lub multimeter los ntsuas qhov voltage (AC).

Txuas qhov kev xeem coj mus rau ABS sensor thiab tig lub log kom tau txais kev nyeem ntawv voltage.

Yog tias tsis muaj nqi ntawm cov khoom siv multimeter, ABS yog faulty. Hloov nws.

Cov iav tiv thaiv

Koj yuav tsum cuam tshuam ntau nrog lubrication thiab cua sov. Yog li ntawd, looj hnab looj tes tiv thaiv cov roj los ntawm cov rau tes. Cov hnab looj tes tuab yuav tiv thaiv koj txhais tes los ntawm kev kub hnyiab thiab txiav los ntawm cov khoom xws li wrenches thiab jacks.

Koj tseem yuav tau tapping nrog rauj. Nyob rau hauv cov ntaub ntawv no, ntau particles yuav tawg mus rau hauv cov huab cua. Yog li ntawd, nws yog ib qho tseem ceeb kom muaj kev tiv thaiv qhov muag. koj siv tau screen tiv thaiv los yog tsom iav ntse.

Summing txog

Rau kev tsav tsheb nyab xeeb, nws yog ib qho tseem ceeb los saib xyuas qhov xwm txheej ntawm ABS sensor. Tam sim no peb paub tias: qhov tshwm sim ntawm rub thiab ntsuas qhov ntsuas ntawm lub dashboard, nrog rau qhov tsis muaj kev nyeem ntawv ntawm lub vaj huam sib luag ntawm multimeter, txhais tau hais tias ABS sensor yog faulty. Tab sis qee zaum koj tuaj yeem tau txais kev nyeem ntawv multimeter, tab sis tseem lub sensor rub thiab teeb tau txais kev cawmdim. Hauv qhov no, koj yuav xav tau kev pab los ntawm tus kws tshaj lij.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
