U011C Lost Communication me ka Rocker Arm Control Module B

Papa Kuhikuhi DTC OBD-II

ʻO ka kamaʻilio nalowale me ka Module Control Rocker Arm B

He aha keʻano o kēia?

ʻO kēia kahi ʻōnaehana kamaʻilio maʻamau ʻōnaehana pilikia helu e hoʻopili i nā hana a me nā hoʻohālikelike o nā kaʻa ʻo OBD-II.

ʻO ke kumu o kēia code ka Rocker Arm B Control Module (RACM-B) a me nā mana mana ʻē aʻe i 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.

Kamaʻilio nā modula me kekahi ma luna o kahi pūnaewele, e like me ka pūnaewele i loaʻa iā ʻoe ma ka home a hana paha. Hoʻohana nā mea hana kaʻa i nā ʻōnaehana pūnaewele. A hiki i ka 2004, ʻo nā ʻōnaehana kamaʻilio waena ʻōnaehana maʻamau (maʻamau ʻole) ka ʻōnaehana kamaʻilio pūkaʻina, a i ʻole SCI; SAE J1850 a i ʻole ke kaʻa ʻōhua PCI; a me Chrysler Collision Detection, a i ʻole CCD. ʻO ka ʻōnaehana maʻamau i hoʻohana ʻia ma hope o 2004 i ʻike ʻia ma ke ʻano he Controller Area Network kamaʻilio, a i ʻole ʻo CAN bus (hoʻohana ʻia a hiki i ka 2004 ma kahi ʻāpana liʻiliʻi o nā kaʻa). Me ka ʻole o kēia kaʻa ʻo CAN, ʻaʻole hiki i nā modula kaohi ke kamaʻilio a loaʻa ʻole paha i kāu mea nānā ʻikepili i ka ʻike mai ka kaʻa, e pili ana i ka pōʻaiapili e pili ai.

ʻO Rocker Arm Control Module B (RACM-B) ka mea maʻa mau ma lalo o ka pāpale, ma ka uhi maʻamau o ka ʻenekini mīkini. ʻO ia pū kekahi o PCM. Loaʻa iā ia ka hoʻokomo mai nā mea ʻikepili ʻokoʻa, pili pololei kekahi o ia mau mea, a hoʻouna ʻia ka hapanui ma luna o kahi ʻōnaehana kamaʻilio kaʻa mai ka modula mana powertrain (PCM). ʻAe kēia mau mea hoʻokomo i ka module e hoʻomaopopo i ka PCM o ke kūlana lima pōhaku no kēlā me kēia paukūʻolokaʻa. ʻAe i ka PCM e kaohi i ka ʻōnaehana wili o ka manawa hoʻololi. Hoʻohana pinepine ʻia i nā kiwikā nunui no nā ʻenehana paukūʻolokaʻa.

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.

Ka nui o nā code a me nā ʻōuli

ʻAʻole koʻikoʻi ke koʻikoʻi ma kēia hihia no ka mea he papa hana kākoʻo kā PCM inā e nalowale ke kamaʻilio me RACM-B.

Pākuʻi ʻia paha nā ʻōuli o ke code U011C:

• ʻO ke kukui anakahi uila (MIL)
• Hōʻike ʻo Mei i ka hoʻokele waiwai / hana maikaʻi wahie
• Hiki paha i ka ʻenekini ke lele i ka hoʻā ʻana, hiki wale nō i ka hana ʻole a i nā wikiwiki nui paha

kumu

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

• Wehe ma CAN bus + a - kaapuni
• Pōkole i ka honua a i ʻole ka lepo i loko o kekahi kaapuni kaʻa ʻōhua CAN
• ʻAʻohe mana a kahua paha i RACM-B
• Kakaʻikahi - hewa ka module control

Nā diagnostics a me nā kaʻina hana hoʻoponopono

ʻO kahi maikaʻi e hoʻomaka ai i kahi diagnostical uila ALL no ka nānā ʻana i ka Bulletins Service Technical (TSB) no kāu kaʻa. ʻO ka pilikia āu e alo nei e ʻike ʻia e kekahi poʻe ma ke kula. Ua hoʻokuʻu ʻia kahi hoʻoponopono kaulana e ka mea hana a hiki ke mālama iā ʻoe i ka manawa a me ke kālā i ka wā o nā diagnostics.

Manaʻo ʻia aia i kahi mea heluhelu kuhi i kēia manawa iā ʻoe, no ka mea hiki iā ʻoe ke kiʻi i nā code a hiki i kēia manawa. E ʻike inā aia kekahi DTC ʻē aʻe e pili ana i ka kamaʻilio pahi a i ʻole ka uila / hoʻā. Inā pēlā, pono ʻoe e hōʻoia mua iā lākou, no ka mea ʻike ʻia ke kuhi hewa inā ʻike ʻoe i ke kuhi U011C ma mua o ka hōʻoia maikaʻi ʻia ʻana o kekahi o nā code i lalo.

Inā ʻo U011C wale nō ke code i loaʻa iā ʻoe mai nā modula ʻē aʻe, e hoʻāʻo e komo i ka RACM-B. Inā hiki iā ʻoe ke komo i nā code mai RACM-B, a laila ʻo ka code U011C he code intermittent a i ʻole code memory. Inā ʻaʻole hiki ke kiʻi ʻia ka RACM-B, a laila ua paʻa ke code U011C i hoʻonohonoho ʻia e nā modula ʻē aʻe a aia ka pilikia.

ʻO ka hāʻule maʻamau, ʻo ia ka hāʻule kaapuni e hopena ai i ka nalowale o ka mana a i ʻole ka lepo i ka module control rocker b.

E hōʻoia i nā fuse a pau e hāʻawi ana i ka module RACM-B ma kēia kaʻa. E hōʻoia i nā kumu āpau no RACM-B. 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, hoʻomaʻemaʻe i nā DTC mai nā modula i hoʻonohonoho i ke code i ka hoʻomanaʻo a ʻike inā hiki iā ʻoe ke kamaʻilio i kēia manawa me ka module RACM-B. Inā loaʻa ke kamaʻilio me ka RACM-B, ʻo ka pilikia he fuse / pili pili paha.

Inā ʻaʻole hiki ke hoʻokumu ʻia ke code a kamaʻilio pū paha me ka module, e huli i nā pilina kamaʻilio CAN kaʻa ma kāu kaʻa, ʻo ka mea nui loa ʻo ka hoʻopili RACM-B, i ʻike pinepine ʻia ma lalo o ka pāpale, ma ka uhi maʻamau o ka ʻenekini mīkini. hiki ke lilo i ʻāpana o ka RMB. E hoʻokaʻawale i ke kaula uila maikaʻi ʻole ma mua o ka hemo ʻana i ka mea hoʻopili mai ka RACM-B. 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.

Hana i kēia mau kaha uila ma mua o ka hoʻopili ʻana i nā mea hoʻopili i ka RACM-B. Pono ʻoe e komo i kahi volt-ohmmeter uila (DVOM). E ʻike pono he mana kou a me ka honua ma ka RACM-B. E kiʻi i ke kiʻikuhi uila a hoʻoholo i kahi e hele ai ka mana nui a me nā lako honua i ka RACM-B. Hoʻohui hou i ka pila ma mua o ka hoʻomau ʻana me ka RACM-B i hemo. E hoʻohui i ke alakaʻi ʻulaʻula o kāu voltmeter i kēlā me kēia B + (uila uila) i loaʻa ka mana i loko o ka hoʻopili RACM-B, a me ke kēpau ʻeleʻele o kāu voltmeter i kahi lepo maikaʻi (inā ʻaʻole maopopo, holo pono ka pou maikaʻi ʻole o ka pākiko). E ʻike ʻoe i ka heluhelu o ka uila uila. E ʻike pono he kumu maikaʻi kāu. E hoʻohui i ka uea ʻulaʻula mai ka voltmeter i ka maikaʻi o ka pākiko (B +) a me ka uea ʻeleʻele i kēlā me kēia honua. Eia hou, pono ʻoe e ʻike i ka anakahi uila i kēlā me kēia manawa āu e kuʻi ai. Inā ʻaʻole, hoʻopololei 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 i ʻole hiki iā ʻoe ke hoʻomaʻemaʻe i ka DTC U011C, ʻo ka mea wale nō e hiki ke hana ʻia ʻo ke ʻimi ʻana i ke kōkua mai kahi mea diagnostic automotive i aʻo ʻia no ka mea e hōʻike ana kēia i kahi hemahema RACM-B. . Pono e hoʻolālā ʻia ka hapa nui o kēia mau RACM-B a hoʻopaʻa ʻia paha i kūpono i ke kaʻa.

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 i kōkua hou me ke code U011C?

Inā makemake ʻoe i kōkua me DTC U011C, 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.
