U0109 Lost Communication me ka Fuel Pump Control Module (FPCM)

U0109 Lost Communication me ka Fuel Pump Control Module (FPCM)

Papa Kuhikuhi DTC OBD-II

Ka kamaʻilio nalo me ka Module Control Pump Fuel (FPCM)

He aha keʻano o kēia?

ʻO kēia kahi kamaʻilio maʻamau DTC e pili ana i ka nui o nā hana a me nā hoʻohālikelike o nā kaʻa, me ka palena ʻole ʻia iā Dodge, Ram, Chevrolet, Ford, GMC, a me VW. ʻO kēia kumu ke ʻano o ka mana o ka paila paila wahie (FPCM) a me nā modula kaohi o ke kaʻa e kamaʻilio ʻole ana 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.

Mālama ka FPCM i ka pauma wahie e pili ana i ka ʻike i loaʻa mai ka module kaohi powertrain (PCM). Inā ʻaʻole i loaʻa ka ʻike, ʻaʻole holo pono ka pauma wahie. Hoʻohana pinepine ʻia kēia mau modula i nā mīkini ʻenekini, ʻoiai ke hoʻonui ʻia nei kā lākou hoʻohana ʻana i nā ʻenekini diesel hou aku.

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.

nā hōʻailona

Hiki ke hoʻopili ʻia nā ʻōuli o kahi ʻenekini U0109:

• ʻO ke kukui anakahi uila (MIL)
• Hoʻomaka ke kaʻa akā ʻaʻole neʻe
• Inā holo ka ʻenekini: haʻalulu; Ka nele o ka mana; Hana maikaʻi ʻole; Misfire i nā paukūʻolokaʻa (hana ʻino)

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
• 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 i kahi kamaʻilio kaʻa a i ʻole pili i ka uila / hoʻā ʻana, e kuhikuhi mua iā lākou. ʻIke ʻia ke kuhi hewa inā ʻike ʻoe i ke kuhi U0109 ma mua o ka hōʻoia a hōʻole ʻia o nā code nui.

Inā hiki i kāu mea hana scan ke komo i nā code pilikia a ʻo ke code wale nō āu e loaʻa mai ai mai nā modula ʻē aʻe ʻo U0109, e hoʻāʻo e kelepona i ka FPCM. Inā hiki iā ʻoe ke kiʻi i nā code mai ka module FPCM, a laila ʻo ka code U0109 he intermittent a i ʻole he code memory. Inā ʻaʻole hiki ke hoʻopili ʻia ka module GPCM, a laila ua paʻa ka code U0109 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.

E hōʻoia i nā fuse a pau e hāʻawi ana i ka FPCM ma kēia kaʻa. E hōʻoia i nā kahua āpau no ka FPCM. 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 āpau e hoʻonohonoho i ke code i ka hoʻomanaʻo a ʻike inā hoʻi ʻo U0109 a i ʻole hiki iā ʻoe ke kāhea i ka module FPCM. Inā ʻaʻohe code i hoʻihoʻi ʻia a kamaʻilio pū ʻia me FPCM i hoʻihoʻi ʻia, pilikia paha ka pilikia i ka fuse / pili paha.

Inā hoʻi ka pāʻālua, e nānā no nā pilina kamaʻilio CAN bus ma kāu kaʻa kikoʻī, ʻo ia hoʻi ka mea hoʻopili FPCM. E hoʻokaʻawale i ke kaula uila maikaʻi ʻole ma mua o ka hemo ʻana o ka mea hoʻopili ma ka FPCM. 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 silikō dielectric kahi e hoʻopili ai nā maʻi.

Hana i kēia mau kaha uila ma mua o ka hoʻopili ʻana i nā mea hoʻopili i ka FPCM. Pono ʻoe e komo i kahi volt volt ohmmeter (DVOM). E ʻike pono he mana kou a me ka honua ma ka FPCM. E kiʻi i ke kiʻikuhi uila a hoʻoholo i kahi e hele ai ka mana mua a me nā lako honua i ka FPCM. Hoʻohui hou i ka pila ma mua o ka hoʻomau ʻana me ka FPCM e hemo mau ana. E hoʻohui i ka uea ʻulaʻula o kāu voltmeter i kēlā me kēia B + (uila uila) i loaʻa i ka mea hoʻopili ma ka module FPCM, a me ka uea ʻeleʻele o kāu voltmeter i kahi lepo maikaʻi (inā ʻaʻole maopopo, hana mau 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 hoʻokomo 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.

Inā ʻaʻole hoʻohana kāu mea hana kaʻa i ka CAN bus no ke kamaʻilio ma waena o ka PCM a me ka AFCM, pono ʻoe e hoʻoholo i nā anakuhi kūpono no kēia kaapuni kamaʻilio.

Inā hala nā ho'āʻo a pau ʻaʻole hiki ke kamaʻilio, a i ʻole hiki iā ʻoe ke hoʻomaʻemaʻe i ka DTC U0109, ʻo ka mea wale nō 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 FPCM hewa. Pono e hoʻolālā ʻia kekahi mau FPCM no ke kaʻa i mea e hoʻokomo pono ai.

Pono kōkua hou me ke code u0109?

Inā makemake ʻoe i kōkua me DTC U0109, 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.
