U0120 Lost Communication me ka Module Control Starter-Generator

U0120 Lost Communication me ka Module Control Starter-Generator

Papa Kuhikuhi DTC OBD-II

Nalowale kamaʻilio me ka Moder Control Starter-Generator

He aha keʻano o kēia?

ʻO kēia kahi ʻōnaehana kamaʻilio maʻamau ʻōnaehana pilikia helu kuhi e pili ana i ka hapa nui o nā kaʻa non-hybrid, akā hiki ke ʻike ʻia ma nā hana a me nā hoʻohālikelike o nā kaʻa hybrid.

ʻO ke kumu o kēia code ka modulator control alternator starter (SGCM) a me nā modula kaohi o ke kaʻa ʻaʻole e kamaʻilio pū kekahi me 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.

Kuhi ka SGCM i ka wela a me ke anuanu o nā pailaka i loaʻa a hoʻololi i ka ʻōnaehana hoʻouka e hōʻoia i nā bateri i ke ʻano kūpono o ka uku. Mālama pū lākou i ka ʻōnaehana hoʻomaka e hoʻoholo i ka likelihood o kahi hana hewa. Hoʻouna ʻia kēia ʻike i ka PCM e hoʻā i ke kukui anakahi uila

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. Ma muli o ka hōʻoia ʻana o kēia ʻōnaehana hoʻomalu powertrain i ka palekana i nā kūlana hana āpau, kahi hopohopo kahi hopohopo i ka wehewehe ʻana i kēia ʻōnaehana. Hoʻohui, nui ka palekana i ka lawelawe ʻana i kēia ʻōnaehana. ALWAYS e nānā i ka ʻike o ka lawelawe ma mua o ka hemo ʻana / hōʻike ʻana i kēia mau ʻōnaehana.

Hiki ke hoʻopili ʻia nā ʻōuli o kahi ʻenekini U0120:

• ʻO ke kukui anakahi uila (MIL)
• Aia ka mea kuhikuhi mode hybrid, inā pili
• ʻAʻole hiki i ke kaʻa ke hoʻomaka a holo paha
• Hiki i ke kaʻa ke holo, akā ma ka ʻenekini ʻaukā, inā wale nō ka hybrid

kumu

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 SGCM - 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.

ʻO ka mea mua, e nānā no nā DTC ʻē aʻe. Inā pili kekahi o kēia mau mea i ke kaʻaahi a i ʻole kahi uila / hybrid e pili ana, ʻike mua iā lākou. ʻIke ʻia ke kuhi hewa inā kuhi ʻoe i ka pāʻālua U0120 ma mua o ka hōʻoia a hōʻole ʻia ʻana o kekahi o nā code nui.

Inā hiki i kāu hāmeʻa scan ke komo i nā DTC a ʻo ka code wale nō āu e huki nei mai nā modula ʻē aʻe ʻo ia ka U0120, e hoʻāʻo e komo i ka module mana hoʻomaka-alternator. Inā hiki iā ʻoe ke komo i nā code mai ka SGCM a laila ʻo ka code U0120 he intermittent a i ʻole he code memory. Inā ʻaʻole hiki ke kiʻi ʻia nā code no ka module SGCM, a laila ua paʻa ka code U0120 i hoʻonohonoho ʻia e nā modula ʻē aʻe a aia ka pilikia.

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

Ma mua o ka hele hou ʻana, e hāʻawi i kahi ana ʻuʻuku: inā he kaʻa hapalua kēia: he ʻōnaehana anakahi uila kiʻekiʻe kēia. Inā ʻaʻole e mālama ʻia nā ʻōlelo aʻoaʻo a / a i ʻole mālama ʻole ʻia nā hana pale a me nā diagnostical a ka mea hana, ʻĀINA paha ka hōʻino ʻana i ka kaʻa a hiki paha ke hōʻeha a ʻeha pilikino iā ʻoe. Inā ʻaʻole ʻoe e maopopo e pili ana i kekahi pae o nā diagnostics, koi nui ʻia ʻoe e waiho i nā diagnostics o kēia code i kēia ʻōnaehana i kekahi mea i hoʻomaʻamaʻa ʻia ma ia.

E hōʻoia i nā fuse āpau e hāʻawi ana i ka SGCM ma kēia kaʻa. E hōʻoia i nā kahua āpau no SGCM. E huli i nā māka heleuma honua 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 U0120 a i ʻole hiki iā ʻoe ke hoʻokaʻaʻike aku iā SGCM. Inā ʻaʻole hoʻihoʻi i ka code a hoʻihoʻi ʻia ka pilina, ʻo ka pilikia he pilikia fuse / pili paha.

Inā hoʻi ka pāʻālua, e nānā i nā pilina CAN bus ma kāu kaʻa kikoʻī, ʻoi loa i ka hoʻopili SGCM.

I KA HOLO ANA I KA HYBRID, HOLOHE I KA PALAPALA HOLOLE NUI E HIKI ANA I KA HANA A KA MANUFACTURER.

E hoʻokaʻawale i ke kaula uila maikaʻi ʻole ma mua o ka hemo ʻana o ka mea hoʻopili ma ka SGCM. 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. Hoʻohui hou i nā mea hoʻopili. Holoi i nā pāʻālua āpau.

Inā hala nā hoʻokolohua a pau ʻaʻole hiki ke kamaʻilio, a i ʻole hiki iā ʻoe ke hoʻomaʻemaʻe i ka DTC U0120, ʻo ka mea wale nō āu e hana ai, ʻo ka ʻimi ʻana i ke kōkua mai kahi mea diagnostic automotive i aʻo ʻia no ka mea e hōʻike ana kēia i kahi SGCM hewa. Pono e hoʻolālā ʻia ka hapa nui o kēia mau SGCM no ke kaʻa i hoʻonohonoho pono ʻia.

Nā kūkākūkā DTC e pili ana

• ʻAʻohe kumuhana pili i kēia manawa i kā mākou kolamu. Kau i kahi kumuhana hou ma ke kolamu i kēia manawa.

Pono kōkua hou me ke code u0120?

Inā makemake ʻoe i kōkua me DTC U0120, 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.
