ʻO ABS (anti-lock brake sensor) he tachometer e ana i ka wikiwiki huila. A laila hoʻouna ʻo ia i ka RPM i helu ʻia i ka Engine Control Module (ECM). Ua ʻike ʻia ʻo ABS ma ke ʻano he mea ʻike wikiwiki huila a i ʻole ABS braking sensor. Loaʻa i kēlā me kēia huila o ke kaʻa kona wikiwiki o ka hoʻololi ʻana, hopu ka sensor ABS i kēia mau hōʻailona wikiwiki.

Ma hope o ka loaʻa ʻana o nā hōʻike wikiwiki huila, hoʻoholo ka ECM i ke kūlana laka no kēlā me kēia huila. ʻO ka uē koke ʻana i ka wā e hoʻopaʻa ʻia ai ka ECM.

Inā ʻino ka ABS o kāu kaʻa, hiki iā ʻoe ke nalowale i ka paʻa uila a me ka mana traction. No laila, he mea pōʻino ke hoʻokele kaʻa me ka ʻike ʻole i ke kūlana o ka sensor ABS.

E nānā i ka mea ʻike ABS inā ʻā ke kukui a me ka hōʻailona ʻike ma ka dashboard o ke kaʻa.

Ma keʻano laulā, no ka hoʻāʻo ʻana i ka sensor ABS, pono ʻoe e kau i nā alakaʻi multimeter ma nā mea hoʻohui uila. A laila pono ʻoe e wili i nā huila o ke kaʻa no ka loaʻa ʻana o ka heluhelu ʻana. Inā ʻaʻohe heluhelu, a laila wehe a make paha kāu sensor ABS.

E hele au i nā kikoʻī hou aku ma kā mākou ʻatikala ma lalo nei.

ʻO nā mea ʻike ABS kekahi o nā mea i hoʻohana pinepine ʻia i nā kaʻa. I ka ʻōnaehana kaʻa hou, aia ka ABS ma ka huila huila. Ma kahi ʻōnaehana kaʻa kuʻuna, aia ia ma waho o ka huila huila - i loko o ka puʻupuʻu hoʻokele. Hoʻopili ʻia ia i kahi mīkini apo i kau ʻia ma kahi rotor haki. (1)

I ka manawa e nānā ai i ka ABS Sensor

Hoʻomālamalama nā mea ʻike a me ka ʻōnaehana hoʻokele traction ke ʻike ka mea ʻike ABS i kahi hana ʻino. Pono ʻoe e nānā no kēia mau hōʻailona hana ʻino ma ka dashboard i ke kaʻa ʻana. Aia ka lama traction ma ka dashboard. (2)

He aha kāu e pono ai ke nānā i ka sensor ABS

Multimeter mīkini
Hoʻopili (koho, hoʻohana wale ʻoe i nā mea ʻike)
ʻO nā ʻeke kaila
ʻO ka pahu heluhelu ABS e kōkua iā ʻoe e heluhelu i nā code ABS a ʻike i ka mea e pono ke pani ʻia
Kālā
Kāpena papahele
Nā mea hana hoʻokomo kaʻa

Makemake au i nā multimeter digital no ka mea hōʻike wale lākou i nā waiwai a i ʻole nā heluhelu ma ka pale. Hoʻohana ʻo Analog i nā kuhikuhi, no laila pono ʻoe e hana i kekahi mau helu.

Pehea e hoʻāʻo ai i kahi sensor ABS: E kiʻi i kahi heluhelu

ʻO ka multimeter ʻekolu mau ʻāpana nui, ʻo ia ka hōʻike, ka pihi koho, a me nā awa. Hōʻike pinepine ka hōʻike i nā helu 3 a hōʻike ʻia nā waiwai maikaʻi ʻole.

E hoʻohuli i ka pihi koho e koho i ka ʻāpana āu e makemake ai e ana. Hiki ia i kēia manawa, voltage a i ʻole ke kū'ē.

Loaʻa i ka multimeter 2 probes i pili i kona mau awa i kapa ʻia ʻo COM a me MAV.

ʻeleʻele pinepine ʻo COM a pili i ka ʻāina kaapuni.

He ʻulaʻula paha ka ʻimi kūpaʻa MAV a pili i ka heluhelu o kēia manawa.

E hahai i keia nā ʻanuʻu maʻalahi e hoʻāʻo i nā mea ʻike ABS āpau me kahi multimeter. E nānā pono i ka manual e ʻike i ka nui o nā huila e kau ana ka mea ʻike ABS a nānā i nā mea ʻike āpau.

E nānā i kā lākou waiwai maʻamau i Ohms.

Eia nā ʻanuʻu:

E kaʻa i kāu kaʻa a e hōʻoia i ka hoʻouna ʻana ma Park a i ʻole Neutral. ma mua o ka hoʻopau ʻana i ka ʻenekini. A laila hoʻonoho i nā kaʻa pilikia.
E hoʻohana i kahi jack e hoʻokiʻekiʻe i ka huila ma ka ʻaoʻao o ka sensor āu e makemake ai e hoʻāʻo. Ma mua o kēlā, ʻoi aku ka maikaʻi o ka hohola ʻana i kahi moena ma ka papahele ma lalo o ka mīkini, kahi e moe ai ʻoe i lalo, a maʻalahi hoʻi e hana i ka hana hoʻoponopono. Mai poina e komo i nā mea pale.
E hoʻokaʻawale i ka mea ʻike ABS mai nā uwea hoʻohui me ka wehe pono ʻana i kona uhi. A laila e hoʻomaʻemaʻe me ka mea holoi hoʻomaʻemaʻe (he ʻano canister ka sensor a loaʻa nā uea hoʻohui).
E hoʻonoho i ka multimeter i ohms. Hoʻoponopono maʻalahi akā paʻa i ka pihi e kuhikuhi i ka hoʻonohonoho ohm. Hōʻike ʻia ka Ohm a i ʻole ke kūʻē ʻana e ka hōʻailona "Ohm".
E hoʻonoho i ka multimeter e hōʻike i ka ʻole ma ka hoohuli mau ana i ke knob hooponopono zero.
E kau i nā uwea ʻimi ma luna o nā mea hoʻopili sensor ABS. No ka mea, ʻaʻole kuhikuhi ʻia ke kūʻē ʻana, ʻaʻole pili ka hopena āu e kau ai ma kēlā me kēia probe. Akā, e mālama iā lākou i kahi mamao e hiki ai ke loaʻa ka heluhelu kūpono. E kali a loaʻa ka waiwai i ʻaelike ʻia.
E nānā pono i nā heluhelu Ohm. E hoʻohālikelike i ka waiwai ohm maʻamau o kāu sensor mai ka manual. Pono ka ʻokoʻa ma lalo o 10%. A i ʻole, pono ʻoe pani i ka mea ike ABS.

ʻO kahi ʻē aʻe, hiki iā ʻoe ke hoʻonohonoho i ka multimeter e ana i ka volta (AC).

Hoʻohui i ke alakaʻi hoʻāʻo i ka sensor ABS a hoʻohuli i ka huila no ka loaʻa ʻana o ka heluhelu ʻana.

Inā ʻaʻohe waiwai ma ka hōʻike multimeter, a laila hewa ka ABS. E pani hou.

Mea pale

Pono ʻoe e launa pū me ka lubrication a me ka wela. No laila, nā pūkeke pale i ka aila mai ke kau ma na kui. Mālama nā mīkina lima mānoanoa i kou mau lima mai ke ahi a ʻoki ʻia mai nā mea e like me nā wrenches a me nā jacks.

E paʻi pū ana ʻoe me ka hāmare. I kēia hihia, nui nā ʻāpana e pahū i ka lewa. No laila, he mea nui ka mālama maka. hiki iā ʻoe ke hoʻohana pale pale a i ʻole nā aniani akamai.

E hōʻuluʻulu

No ka hoʻokele palekana, pono e nānā i ke kūlana o ka sensor ABS. I kēia manawa ua ʻike mākou: ʻo ke ʻano o ka huki a me ka hōʻailona sensor ma ka dashboard, a me ka ʻole o ka heluhelu ʻana ma ka panel o ka multimeter, ʻo ia ka hewa o ka sensor ABS. Akā i kekahi manawa hiki iā ʻoe ke kiʻi i ka heluhelu multimeter, akā mālama ʻia ka huki sensor a me ka mālamalama. I kēia hihia, pono ʻoe i ke kōkua o kahi loea loea.

E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
