U0129 Lost Communication me ka Brake Control Module (BSCM)

Code pilikia OBD-II - U0129 Pepa ʻIkepili

Ka kamaʻilio nalo me ka mana o ka brake (BSCM)

Hōʻike kēia code ʻaʻole kamaʻilio pū ka Brake Control Module (BSCM) a me nā modula mana ʻē aʻe o ke kaʻa. ʻO ka papahana i hoʻohana pinepine ʻia no ke kamaʻilio ʻana ʻo ia ka Controller Area Network bus communication a i ʻole, ʻoi aku ka maʻalahi, CAN bus.

He aha ka manaʻo o DTC U0129?

ʻO kēia kahi ʻōnaehana kamaʻilio maʻamau ʻōnaehana pilikia helu helu e hoʻopili i ka nui o nā hana a me nā hoʻohālikelike o nā kaʻa.

ʻO ke kumu o kēia code ʻaʻole ke kamaʻilio o ka modula kaohi rem (BSCM) a me nā modula mana ʻē aʻe ma luna o ka kaʻa i kekahi i kekahi. ʻO ka circuitry i hoʻohana mau ʻia no ke kamaʻilio ʻike ʻia ka Controller Area Bus kamaʻilio, a i ʻole ʻo ka CAN bus.

Me ka ʻole o kēia CAN bus, ʻaʻole hiki i nā modula kaohi ke kamaʻilio a ʻaʻole paha e loaʻa i kāu mea hana scan i ka ʻike mai ka kaʻa, e pili ana i ka kaapuni i pili.

Loaʻa i ka BSCM ʻikepili hoʻokomo mai nā sensor like ʻole, pili pololei kekahi o ia mea a hoʻouna ʻia kekahi o lākou ma kahi ʻōnaehana kamaʻilio kaʻa ʻōhua. ʻAe kēia mau mea hoʻokomo i ke kōmike e kāohi i ka hoʻoulu ʻana o nā paleki paʻa, akā hiki ke hoʻohana ʻia ma ke ʻano he braking basic / anti-braking system. Hoʻohana ʻia kēia ʻōnaehana ma nā kaʻa hybrid, akā hiki ke hoʻohana ʻia no nā noi ʻē aʻe inā manaʻo ka mea hana he kūpono.

Hiki ke hoʻololi i nā ʻanuʻu troubleshooting ma muli o ka mea hana, ke ʻano o ka ʻōnaehana kamaʻilio, ka helu o nā uea, a me nā kala o nā kaula i ka ʻōnaehana kamaʻilio.

Kaumaha a me nā ʻōuli

ʻO ka paʻakikī i kēia hihia pili i ka ʻōnaehana. ʻO ka maʻamau, i ka hanana o kahi kōkuhi kōkuhi kōkuhi kō ʻole, ʻo ka paʻa wale ke kumu / ʻaʻohe ʻōnaehana palaka anti-laka / ʻaʻohe ʻōnaehana kaohi traction / ʻaʻohe ʻōnaehana ʻōnaehana wawahi holomua.

Hiki ke hoʻopili ʻia nā ʻōuli o kahi ʻenekini U0129:

• Hoʻā ʻia ke kukui ʻōkuhi ʻulaʻula
• Ka hōʻino ʻana o ka ʻōnaehana paʻa

Nā kumu o ka hewa U0129

ʻO ka maʻamau no ke kau ʻana i kēia code ka:

• E wehe ma CAN + kaʻa kaʻa kaʻa
• Wehe i ke kaʻaahi CAN - kaapuni uila
• Kaapuni pōkole i ka mana ma kekahi kaapuni kaʻaahi CAN
• Pōkole i ka honua i kekahi kaapuni kaʻaahi CAN
• Nalo ka mana a i ʻole ka lepo i ka BSCM - ka mea maʻamau
• Kakaʻikahi - hewa ka module control

Nā diagnostics a me nā kaʻina hana hoʻoponopono

ʻO kahi wahi hoʻomaka maikaʻi ke nānā mau nei i ka Bulletins Service Technical (TSB) no kāu kaʻa ponoʻī. ʻO kou pilikia he pilikia i ʻike ʻia me kahi mea hana i hoʻokuʻu ʻia a hoʻokuʻu ʻia hiki ke mālama iā ʻoe i ka manawa a me ke kālā i ka wā o nā diagnostics.

Inā hiki i kāu mea hana scan ke komo i nā code pilikia a ʻo ka code wale nō āu e huki nei mai nā modula ʻē aʻe ʻo U0129, e hoʻāʻo e komo i ka BSCM. Inā hiki iā ʻoe ke komo i nā code mai ka BSCM, a laila, ʻo ka code U0129 he intermittent a i ʻole he code memory. Inā ʻaʻole hiki ke kiʻi ʻia nā code no ka module BSCM, a laila code U0129 i hoʻonohonoho ʻia nā modula ʻē aʻe a ʻoi aku ka pilikia.

ʻO ka hemahema maʻamau ka nalowale o ka mana a i ʻole ka lepo i ka BSCM.

E hōʻoia i nā fuse a pau e hāʻawi ana i ka BSCM ma kēia kaʻa. E hōʻoia i nā kahua āpau no ka BSCM. E huli i nā helu hoʻopili paʻa ma luna o ke kaʻa a hōʻoia i ka maʻemaʻe a me ka palekana o kēia mau pilina. Inā pono, hemo iā lākou, e lawe i kahi uea br brush palaki a me ka palaoa ʻaʻala / wai a hoʻomaʻemaʻe i kēlā me kēia, nā mea hoʻopili a me kahi e hoʻopili ai.

Inā ua hoʻoponopono ʻia kekahi mau mea, holoi i nā DTC mai ka hoʻomanaʻo a ʻike inā hoʻi ʻo U0129 a i ʻole hiki iā ʻoe ke kāhea i ka BSCM. Inā ʻaʻole i hoʻihoʻi ʻia kahi code a hoʻihoʻi ʻia ke kamaʻilio, ʻo ka pilikia he pilikia fuse / pili paha.

Inā hoʻi ka pāʻālua, e nānā i nā pili kaʻa CAN C ma kāu kaʻa kikoʻī, ʻo ia hoʻi ka mea hoʻopili BSCM. E hoʻokaʻawale i ke kaula uila maikaʻi ʻole ma mua o ka hemo ʻana o ka mea hoʻopili ma ka BSCM. I ka manawa e ʻike ʻia, nānā i nā mea hoʻopili a me nā pilina. E nānā i nā ʻōpala, nā ʻūpā, nā kaula i hōʻike ʻole ʻia, nā kaha kuni, a i ʻole ka plastic hoʻoheheʻe ʻia. E hoʻokaʻawale i nā mea hoʻopili a nānā pono i nā kikowaena (nā ʻāpana hao) i loko o nā mea hoʻopili. ʻIke inā nānā lākou i ke ahi a i ʻole he aniani ʻōmaʻomaʻo e hōʻike ana i ka pala. Inā pono ʻoe e hoʻomaʻemaʻe i nā maʻi, e hoʻohana i kahi mea hoʻomaʻemaʻe pili uila a me kahi palaki palaki uila. ʻAe e hoʻomaloʻo a hoʻopili i ka hamo uila kahi i pili ai nā maʻi.

E hana i kēia mau māka uila ma mua o ka hoʻohui ʻana i nā mea hoʻohui i ka BSCM. Pono ʻoe e komo i kahi kikohoʻe volt/ohmmeter (DVOM). E hōʻoia i ka mana a me ka lepo ma ka BSCM. E kiʻi i ke kiʻikuhi wiring a hoʻoholo i kahi e komo ai ka mana nui a me nā lako ʻāina i ka BSCM. Hoʻopili hou i ka pākaukau ma mua o ka hoʻomau ʻana me ke pio ʻole o ka BSCM. E hoʻokuʻi i ke alakaʻi ʻulaʻula o kāu voltmeter i kēlā me kēia B+ (ka uila uila) i hoʻopili ʻia i loko o ka mea hoʻohui BSCM, a me ke alakaʻi ʻeleʻele o kāu voltmeter i kahi lepo maikaʻi (inā maopopo ʻole, hana mau ka maikaʻi ʻole o ka pākaukau). ʻIke ʻoe i ka heluhelu ʻana o ka puʻu uila. E hōʻoia he kumu maikaʻi kāu. E hoʻohui i ke keʻokeʻo ʻulaʻula o ka voltmeter i ka pākaukau maikaʻi (B+) a me ke alakaʻi ʻeleʻele i kēlā me kēia kaapuni honua. Eia hou, pono ʻoe e ʻike i ka uila uila i kēlā me kēia manawa āu e hoʻopili ai. Inā ʻaʻole, hoʻoponopono i ka mana a i ʻole kaapuni honua.

A laila e nānā i nā kaapuni kamaʻilio ʻelua. E huli iā CAN C+ (a i ʻole HSCAN+) a me CAN C- (a i ʻole HSCAN - kaapuni). Me ka uwea ʻeleʻele o ka voltmeter i hoʻopili ʻia i kahi lepo maikaʻi, e hoʻopili i ke kelepona ʻulaʻula i CAN C+. Me ke kī a paʻa ka mīkini, pono ʻoe e ʻike ma kahi o 2.6 volts me ka liʻiliʻi liʻiliʻi. A laila e hoʻohui i ka uwea ʻulaʻula o ka voltmeter i ke kaapuni CAN C-. Pono ʻoe e ʻike ma kahi o 2.4 volts me ka liʻiliʻi liʻiliʻi. Hōʻike nā mea hana ʻē aʻe iā CAN C- ma kahi o 5V a me kahi kī oscillating me ka hemo ʻana o ka ʻenekini. E nānā i nā kikoʻī o kāu mea hana.

Inā hala nā ho'āʻo a pau ʻaʻole hiki ke kamaʻilio, a ʻaʻole hiki iā ʻoe ke hoʻonohonoho hou i ka DTC U0129, ʻo ka mea wale nō e hana ai, ʻo ka ʻimi ʻana i ke kōkua mai ke kanaka diagnostic automotive i aʻo ʻia, no ka mea, e hōʻike ana kēia i kahi BSCM hewa. Pono e hoʻolālā ʻia ka hapa nui o kēia mau BSCM no ke kaʻa i mea e hoʻokomo pono ʻia.

Pono kōkua hou me ke code u0129?

Inā makemake ʻoe i kōkua me DTC U0129, kau i kahi nīnau i nā manaʻo ma lalo o kēia ʻatikala.

OLELO HOOLAHA. Hāʻawi ʻia kēia ʻike no ka ʻike wale nō. ʻAʻole ia e manaʻo ʻia e hoʻohana ʻia ma ke ʻano he ʻōlelo hoʻomaikaʻi a ʻaʻole kuleana mākou no kekahi hana āu e hana ai i kekahi kaʻa. Pale ʻia ka ʻike āpau ma kēia pūnaewele e nā kuleana kope.
