ABS (anti-lock brake sensor) ke tachometer e lekanyang lebelo la mabili. E ntan'o romela RPM e baloang ho Engine Control Module (ECM). ABS e boetse e tsejoa e le sensor ea lebelo la lebili kapa sensor ea braking ea ABS. Lebili le leng le le leng la koloi le na le lebelo la lona la ho potoloha, sensor ea ABS e tšoara matšoao ana a lebelo.

Kamora ho fumana litlaleho tsa lebelo la mabili, ECM e khetha boemo ba senotlolo bakeng sa lebili le leng le le leng. Ho lla ka tšohanyetso ha braking ho bakoa ke ho koala ha ECM.

Haeba ABS ea koloi ea hau e sa sebetse hantle, u ka lahleheloa ke botsitso ba elektronike le taolo ea ho hula. Kahoo, ho kotsi ho khanna koloi ntle le ho tseba boemo ba kutlo ea ABS.

Lekola kutlo ea ABS haeba sesupo sa ho hula le kutlo se bonesa dashboard ea koloi.

Ka kakaretso, ho leka sensor ea ABS, o hloka ho kenya li-multimeter lead ho lihokelo tsa motlakase. Joale o hloka ho bilika mabili a koloi ho fumana 'malo oa motlakase. Haeba ho sa baloe, sensor ea hau ea ABS e ka ba e butsoe kapa e shoele.

Ke tla kena ka ho qaqileng haholoanyane sehloohong sa rona se ka tlase.

Li-sensor tsa ABS ke tse ling tsa li-sensor tse sebelisoang haholo likoloing. Lenaneong le lecha la mariki, ABS e fumaneha sebakeng sa mabili. Sistimi ea mariki ea setso, e fumaneha ka ntle ho hub ea mabili - ka har'a knuckle ea ho tsamaisa. E hokahane le lesela la selikalikoe le behiloeng holim'a rotor e robehileng. (1)

Nako ea ho Lekola Sensor ea ABS

Li-sensor le sistimi ea taolo ea ho ts'oara lia khanya ha sensor ea ABS e lemoha ho se sebetse hantle. U lokela ho shebella matšoao ana a ho se sebetse ha sensor ho dashboard ha u ntse u khanna. Lebone la traction le fumaneha habonolo dashboard. (2)

Ke khetha li-multimeter tsa dijithale hobane li bonts'a boleng kapa lipalo skrineng. Analog e sebelisa litsupa, kahoo o tla hloka ho etsa lipalo.

Mokhoa oa ho Lekola Sensor ea ABS: Fumana ho Bala

Multimeter e na le likarolo tse tharo tsa mantlha, e leng ponts'o, konopo ea khetho, le likou. Pontšo hangata e tla bonts'a linomoro tse 3 mme boleng bo fosahetseng le bona bo ka bonts'oa.

Fetola konopo ea khetho ho khetha yuniti eo u batlang ho e metha. E ka ba ea hona joale, ea motlakase kapa ea ho hanyetsa.

Multimeter e na le li-probes tse 2 tse hokahaneng le likoung tsa eona tse ngotsoeng COM le MAV.

Hangata COM e ntšo ebile e hokahane le sebaka sa potoloho.

MAV ea ho hanyetsa probe e ka 'na ea e-ba khubelu' me e amana le 'malo oa hona joale.

Latela tsena mehato e bonolo ea ho leka li-sensor tsohle tsa ABS ka multimeter. Etsa bonnete ba hore u sheba bukana ho bona hore na sensor ea ABS e holim'a mabili a makae 'me u hlahlobe li-sensor tsohle.

Ela hloko boleng ba bona bo tloaelehileng ho Ohms.

Mehato ke ena:

Paka koloi ea hau 'me u netefatse hore phetiso e teng Park kapa Neutral. pele o tima enjene. Ebe u beha mariki a tšohanyetso.
Sebelisa jack ho phahamisa lebili haufi le sensor eo u batlang ho e leka. Pele ho moo, ho molemo ho ala mokato fatše tlas'a mochine, oo u ka robalang ho oona, 'me ho loketse ho etsa mosebetsi oa ho lokisa. U se ke ua lebala ho roala lisebelisoa tsa tšireletso.
Tlosa sensor ea ABS ho lithapo tse hokelang ka ho tlosa sekoaelo sa eona ka mokhoa o sireletsehileng. Ebe u e hloekisa ka brake cleaner (sensor e na le sebopeho sa canister mme e na le likhoele tse hokelang).
Beha multimeter ho ohms. Fetola konopo feela empa u tiile ho supa boemo ba ohm. Ohm kapa khanyetso e hlalosoa ka letšoao "Ohm".
Beha multimeter ho hlahisa zero ka ho phethola kotola ea zero butle-butle.
Beha likhoele tsa probe ho likhokahano tsa sensor ea ABS. Kaha khanyetso ha e na tataiso, ha ho na taba hore na u beha sepheo sefe ho probe ka 'ngoe. Empa li boloke hole kamoo u ka khonang ho bala hantle. Emela ho fumana boleng bo lumellanoeng.
Ela hloko ho bala Ohm. E bapise le boleng ba ohm bo tloaelehileng ba sensor ea hau ho tsoa bukeng. Phapang e tlameha ho ba ka tlase ho 10%. Ho seng joalo, u tlameha nka sebaka sa sensor ea ABS.

Ntle le moo, o ka seta multimeter ho metha voltage (AC).

Hokela teko ho isa ho sensor ea ABS 'me u fetole lebili ho fumana molumo oa motlakase.

Haeba ho se na boleng ho pontšo ea multimeter, joale ABS e fosahetse. E nkele sebaka.

Lisebelisoa tse sireletsang

U tlameha ho sebelisana haholo le lubrication le mocheso. Kahoo, li-gloves thibela oli ho kena lipekere. Liatlana tse teteaneng li tla sireletsa matsoho a hau hore a se ke a chesoa le ho seha linthong tse kang li-wrenches le li-jack.

Hape u tla be u tlanya ka hamore. Tabeng ena, likaroloana tse ngata li tla phatloha moeeng. Ka hona, ke habohlokoa ho ba le tšireletso ea mahlo. u ka sebelisa mosireletsi wa skrine kapa digalase tse bohlale.

Ho akaretsa

Bakeng sa ho khanna ka mokhoa o sireletsehileng, ho bohlokoa ho beha leihlo boemo ba sensor ea ABS. Hona joale rea tseba hore: ponahalo ea pontšo ea ho hula le ea sensor ho dashboard, hammoho le ho ba sieo ha ho baloa phanele ea multimeter, ho bolela hore sensor ea ABS e fosahetse. Empa ka linako tse ling u ka fumana ho baloa ha multimeter, empa leha ho le joalo, ho hula ha sensor le leseli li bolokiloe. Tabeng ena, o tla hloka thuso ea setsebi sa theknoloji.
