Nalowale kamaʻilio me ke kāmela huli hope

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 kēia kuhi ʻo ia hoʻi ka module kamera hope (CMR) a me nā modula mana ʻē aʻe ma 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.

Aia ka module kāmela hope (CMR) ma hope o ka panina hope a i ʻole ka pahu hope / poʻi papa, malia paha i ka pahu. Loaʻa iā ia ke komo mai nā ʻano ʻikepili ʻokoʻa, pili pololei kekahi o ia mau mea, a hoʻouna ʻia ka hapa nui ma luna o kahi ʻōnaehana kamaʻilio kaʻa mai ka modula mana powertrain (PCM). ʻAe kēia mau mea hoʻokomo i ka module e hoʻoholo i ka mamao ma waena o ke kaʻa a me kekahi mea ma hope o ia. Hāʻawi pū kekahi i kahi hiʻohiʻona hiʻohiʻona o ka mea ma hope o ke kaʻa ke huli aʻe ka mea koho kapa.

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 ka koʻikoʻi ma kēia hihia, ʻoiai he mea hana kēia no ka pono o nā mea kūʻai aku, a i ka wā o ka pau ʻole o ka mana, aia mau kahi hana lima. ʻAʻole ka hopena o ka hana CMR i ka hana kaʻa i kekahi ʻano.

Hiki i nā ʻōuli o ke code U0264 ke hoʻopili pū:

• Dashboard Tone / CMR
• Aia ka pahupaʻikiʻi ke ʻole huli i ka ʻaoʻao
• ʻAʻole huli ke kāmera / ʻaʻole kani ke hele aku i kahi mea i ʻike ʻia

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 ka module CMR
• 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 ʻoe e hōʻoia i ka pāʻālua U0264 ma mua o ka ʻike maikaʻi ʻia ʻana o kekahi o nā code i lalo.

Inā ʻo U0264 wale nō ke code i loaʻa iā ʻoe mai nā modula ʻē aʻe, e hoʻāʻo e komo i ka CMR. Inā hiki iā ʻoe ke kiʻi i nā code mai ka CMR, a laila ʻo ka code U0264 he intermittent a i ʻole he code memory. Inā ʻaʻole hiki iā ʻoe ke komo i ka CMR, a laila code U0264 i hoʻonohonoho ʻia nā modula ʻē aʻe i ka hana a aia ka pilikia.

ʻO ka hāʻule maʻamau, ʻo ia ka pōʻino kaapuni e hopena ai i ka nalowale o ka mana a i ʻole ka lepo ma ke kua o ka module kamera.

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

Inā ʻaʻole hiki ke hoʻokumu ʻia ke code a kamaʻilio pū paha me ka module, e huli i nā pilina kamaʻilio CAN kaʻa ma luna o kāu kaʻa, ʻo ka mea nui ʻo ka hoʻopili CMR, aia ma hope o ka ʻaoʻao hope a i ʻole ka pahu hope / ʻaoʻao poʻomanaʻo, malia paha i ka pahu. E hoʻokaʻawale i ke kaula uila maikaʻi ʻole ma mua o ka hemo ʻana o ka mea hoʻopili ma ka CMR. 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 CMR. Pono ʻoe e komo i kahi mika volt ohm mika (DVOM). E hōʻoia i ka mana o ka CMR a me ka honua. E kiʻi i ka diagram pilina a hoʻoholo i kahi e hele ai ka mana nui a me nā pilina o ka honua i ka CMR. Hoʻohui hou i ka pila ma mua o ka hele ʻana, me ka CMR paʻa ʻole i ka manawa. Hoʻohui i ka uea ʻulaʻula o ka voltmeter i kēlā me kēia B + (uila uila) ke kumu mana e hele nei i ka hoʻopili CMR, a me ka uea ʻeleʻele o ka voltmeter i kahi lepo maikaʻi (inā ʻaʻole maopopo, holo pono ka pou maikaʻi ʻole o ka pākuhi). 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, troubleshoot 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 hoʻokolohua a pau ʻaʻole hiki ke kamaʻilio, a ʻaʻole hiki iā ʻoe ke hoʻihoʻi hou i ka DTC U0264, 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 hemahema CMR. Pono e hoʻolālā ʻia ka hapa nui o kēia mau CMR i mea e hoʻokomo pono ai 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 U0264?

Inā makemake ʻoe i kōkua me DTC U0264, 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.
