U0198 Nalowale Kūkā me ka Modem Control Telematic

Papa Kuhikuhi DTC OBD-II

Nalowale kamaʻilio me ka mana ʻōnaehana Telematic

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 ʻaʻole ke kamaʻilio ʻana o nā module telematics control (TCM) a me nā modula mana ʻē aʻe ma luna o ka kaʻa 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 ka mana mana telematics (TCM) aia ma hope o ka dashboard, ma waena o ke kaʻa. Hiki ke loaʻa iā ia ma ka hope o ke kaʻa i loko o ka pahu a i ʻole ke keʻena waiho waho. 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 mole e hōʻike i ka ʻike i ke ala pololei ma ka helu ʻana i ke kūlana o ke kaʻa a hoʻouna i kēia ʻike ma luna o ka pahi ʻikepili i ka module hoʻokele a i ka ʻōnaehana hōʻike cluster / hōʻike nui.

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

Hiki ke koʻikoʻi ke koʻikoʻi ma kēia hihia inā hoʻouna ka TCM i ka ʻikepili kūpono ʻole i ka module / ʻōnaehana hōʻike, a laila hāʻawi i ka ʻike hoʻokele kūpono ʻole.

Hiki i nā ʻōuli o ke code U0198 ke hoʻopili pū:

• Hāʻawi ʻo TCM i kahi ʻike / kani / malia paha ka pale hakahaka
• ʻAʻole huli ʻo TCM / ʻaʻole holo

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 TCM
• 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 U0198 ma mua o ka ʻike maikaʻi ʻia ʻana o kekahi o nā code i lalo.

Inā ʻo U0198 wale nō ke code āu e loaʻa ai mai nā modula ʻē aʻe, e hoʻāʻo e komo i ka TCM. Inā hiki iā ʻoe ke komo i nā code mai ka TCM, a laila ʻo ka code U0198 he code intermittent a i ʻole code memory. Inā ʻaʻole hiki ke kiʻi ʻia ka TCM, a laila code U0198 i hoʻonohonoho ʻia nā modula ʻē aʻe a paʻa ka pilikia.

ʻO ka hāʻule maʻamau, ʻo ia ka hāʻule kaapuni i hopena i ka nalowale o ka mana a i ʻole ka lepo i ka module telematics.

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

Inā hoʻi ʻole ke code a kamaʻilio pū paha me ka module, e huli i nā pilina kamaʻilio CAN bus ma kāu kaʻa, ʻo ka mea nui o ka hoʻopili TCM, aia ma hope o ka dashboard, maʻamau ma waenakonu o ka kaʻa. hiki ke loaʻa ma ka hope o ke kaʻa i loko o ka pahu a i ʻole waihona ukana i hope. E hoʻokaʻawale i ke kaula uila maikaʻi ʻole ma mua o ka hemo ʻana o ka mea hoʻopili ma ka TCM. 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 TCM. Pono ʻoe e komo i kahi kikohoʻe volt/ohmmeter (DVOM). E hōʻoia i ka mana a me ka lepo o ka TCM. E kiʻi i ke kiʻikuhi wiring a hoʻoholo i kahi e komo ai ka mana nui a me nā lako lepo i ka TCM. Hoʻohui i ka pākaukau ma mua o ka hoʻomaka ʻana me ka TCM pio. E hoʻohui i ke kēpau ʻulaʻula o kāu voltmeter i kēlā me kēia lako B+ (voltage batery) e hele ana i loko o ka mea hoʻohui TCM, a me ke alakaʻi ʻeleʻele o kāu voltmeter i kahi lepo maikaʻi (inā maopopo ʻole, e hana mau ana ka maikaʻi ʻole o ka pākaukau). Pono ʻoe e ʻike i ka heluhelu ʻana o ka pākaukau. 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 hoʻokolohua āpau a ʻaʻole hiki ke kamaʻilio, a ʻaʻole hiki iā ʻoe ke hoʻomaʻemaʻe i ka DTC U0198, 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 kuhikuhi ana kēia i kahi TCM hewa. Pono e hoʻolālā ʻia ka hapa nui o kēia mau TCM e hoʻokomo pono i ke kaʻa.
