P0685 Open control circuit wa ECM / PCM kulandirana kwamagetsi

Tsamba la deta la DTC P0685-OBD-II

Tsegulani dera loyendetsa la kulandirana kwa magetsi kwa injini yolamulira / yoyang'anira injini

Kodi cholakwika code P0685 chimatanthauza chiyani?

Izi Diagnostic Trouble Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse za 1996 (Honda, VW, Ford, Dodge, Chrysler, Acura, Audi, GM, etc.).

Ngakhale chilengedwe chawo, injini zimasiyanasiyana pakati pamakina ndipo zimatha kukhala ndi zifukwa zosiyana ndi code iyi.

Zondichitikira ine, chikhalidwe cholepheretsa kuyamba kuyenera kutsagana ndi nambala ya P0685. Nambala iyi ikasungidwa mu module powertrain control module (PCM), zikutanthauza kuti mphamvu yamagetsi yotsika kapena yopanda mphamvu yapezeka mu dera lomwe limapereka mphamvu yamagetsi ku PCM.

Magalimoto ambiri okhala ndi OBD-II amagwiritsa ntchito ma relay kuti apereke magetsi a batri ku PCM, pomwe ena amangogwiritsa ntchito makina osakanikirana. Ma relay nthawi zambiri amakhala ndi mapangidwe apini asanu. Malo olowera oyambira amalandila voliyumu ya batri ya DC, cholumikizira chapansi chimayikidwa pa injini kapena chassis, cholumikizira chachiwiri chimalandira mphamvu ya batri (kudzera pagawo losakanikirana) pomwe choyatsira moto chimayikidwa pa "ON". Chotsatira chachinayi ndichotulutsa PCM, ndipo chachisanu ndi chiwongoladzanja ndi waya wamagetsi a controller network (CAN).

Makina oyatsira ali pamalo a "ON", magetsi amagwiritsidwa ntchito pachachingwe chaching'ono mkati mwakulandirana. Izi zimabweretsa kutseka kwa olumikizana nawo mkati mwazomwezo; kumaliza gawo, potero kumapereka mphamvu yamagetsi kubotolo potulutsa ndikutumiza ku PCM.

Zizindikiro

Popeza nambala ya P0685 nthawi zambiri imatsagana ndi chiyambi cholepheretsa, kunyalanyaza sizokayikitsa. Ngati nambala iyi ilipo ndipo injini iyamba, ikuyesa kuti ndi PCM yolakwika kapena pulogalamu yolakwika ya PCM.

Kuwala kwa Check Engine kungayatse, ngakhale galimotoyo ingakhale ikuyendabe. Malingana ndi gwero la vuto, galimotoyo ikhoza kuyamba koma osayamba, kapena idzayamba koma ndi mphamvu yochepa - kapena "modekha".

Zomwe Zimayambitsa DTC P0685

Monga ndi DTC iliyonse, pakhoza kukhala zifukwa zambiri. Chimodzi mwazofala kwambiri ndikungoyendetsa kolakwika kwa PCM. Zotheka zina ndi monga fuse yowombedwa, kagawo kakang'ono, kulumikizana koyipa, zovuta za batri monga chingwe chosokonekera, ndipo, nthawi zina, PCM yoyipa kapena ECM.

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Zolakwika za PCM Power Relay
• Lama fuyusi kapena lama fuyusi.
• Zowononga kapena zowononga zolumikizira kapena zolumikizira (makamaka pafupi ndi kulandirana kwa PCM)
• Kusintha koyatsira kolakwika
• Pang'ono kapena osadulidwa kwathunthu pamagetsi oyatsira
• Chingwe cha batri chotseguka kapena chonyowa chimatha
• Batire yotsika
• Low voltage poyambira
• Faulty Engine Control Module (ECM) Power Relay
• Chingwe chamagetsi cha ECM ndi chotseguka kapena chachifupi.
• Mphamvu yozungulira ya ECM yoyipa
• Mtengo wa ECU
• Kusagwira ntchito ECM Kodi izi zikutanthauza chiyani?

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Monga momwe zilili ndi ma code ena ambiri amtunduwu, yambitsani matenda anu poyang'ana mwakathithi zingwe zolumikizira, zolumikizira, ndi zida zamagetsi. Samalani kwambiri ma relays osatetezedwa omwe atha kutuluka m'malo awo kapena atha kukhala ndi mapazi kapena zotumphukira. Izi zimawonekera makamaka malo olandila kapena otonthoza ali pafupi ndi batire kapena malo ozizira. Chongani batire ndi chingwe batire malekezero kwa zikayamba ndi dzimbiri kwambiri. Konzani kapena sinthani zolakwika ngati kuli kofunikira.

Mufunika sikani (kapena code reader), digito volt / ohmmeter (DVOM), ndi chithunzi cholumikizira. Zithunzi zolumikizira zitha kupezeka kuchokera kwa wopanga (zolemba zamtundu kapena zofanana) kapena kudzera pagwero lachiwiri monga All Data. Musanagule bukuli, onetsetsani kuti lili ndi chithunzi cholumikizira dera la PCM.

Ndisanayambe ndi matendawa, ndikufuna nditenge ma DTC onse osungidwa (pogwiritsa ntchito sikani kapena code code) ndikuzilemba kuti zidzawunikenso mtsogolo ngati zingafunike. Ndikufunanso kudziwa chilichonse chazomwe chimayimitsa chimango. Izi zitha kukhala zothandiza ngati vuto lomwe likufunsidwa limachitika mwakanthawi.

Kuyambira ndi kulandirana kwamagetsi (kwa PCM), onetsetsani kuti pali magetsi a batri pamalo olowera oyambira. Onaninso chithunzithunzi cha waya, cholumikizira, kapena pinout kuchokera mu buku lothandizira (kapena chofanana) ndi komwe kuli munthu aliyense. Ngati mulibe magetsi, ganizirani kulumikizana kolakwika pa fuseti kapena ulalo wosavuta.

Kenako yang'anani malo owonjezera olowera. Ngati mulibe magetsi, ganizirani lama fuyusi kapena cholumikizira cholakwika (magetsi).

Tsopano yang'anani chizindikiro cha pansi. Ngati kulibe chizindikiro cha nthaka, fufuzani malo, zingwe zamagetsi zolumikizira, mutu wa chassis, ndi chingwe cha batri chimatha.

Ngati masekeli onsewa ali bwino, onani ma voliyumu omwe amatulutsa pamagetsi omwe amapereka magetsi ku PCM. Ngati mulibe magetsi m'mabwalo awa, ganizirani kulandila kolakwika.

Ngati zotuluka zamagetsi zilipo, yang'anani magetsi pamakina olumikizira PCM. Ngati mulibe magetsi, yambani kuyesa makina amagetsi. Onetsetsani kuti mwachotsa olamulira pamakina musanayese kukana ndi DVOM. Konzani kapena sinthani ma circuits otseguka kapena afupikitsa ngati kuli kofunikira.

Ngati pali magetsi pa PCM, mukuganiza kuti ndi yolakwika kapena ili ndi pulogalamu yolakwika.

• Mafotokozedwe a "poyatsira poyatsira" pamenepa amangonena za gawo lamagetsi.
• Kusintha yolandirana yofanana (yolingana manambala) yoyeserera kungakhale kothandiza kwambiri.
• Nthawi zonse bwezerani kulandiranso pamalo ake oyambayo posintha cholakwika chatsopano ndi chatsopano.
• Mukayang'ana makinawo, onetsetsani kuti maderawo ali pamagetsi ambiri.

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P0685

Popeza kuti code iyi imagwirizanitsidwa ndi makina ovuta a zigawo zamagetsi, n'zosavuta kuthamangira chisankho ndikungosintha PCM, ngakhale kuti nthawi zambiri izi sizili vuto ndipo zimafuna kukonzanso kokwera mtengo kwambiri. Zingwe za batri zowonongeka kapena kugwirizana koyipa nthawi zambiri zimayambitsa mavuto ndi PCM relay, kotero iwo ayenera kukhala gawo lachibadwa la mayesero.

Kodi P0685 ndi yowopsa bwanji?

Ngakhale galimoto yanu ikugwira ntchito ikakhazikitsidwa, ikhoza kuyimitsa kapena kukana kuyiyamba nthawi iliyonse. Zida zofunika zotetezera zingathe kukhudzidwanso - mwachitsanzo, magetsi anu amatha kuzimitsa mwadzidzidzi, zomwe zingakhale zoopsa ngati mukuyendetsa galimoto usiku pamene izi zikuchitika. Ngati mukukumana ndi zizindikiro za vuto, monga wailesi yosagwira ntchito, muyenera kulankhulana ndi katswiri kuti muzindikire ndi kukonza vutoli mwamsanga kuti mupewe kuwonongeka kwina kwa zigawo zina.

Ndi kukonza kotani komwe kungakonze P0685?

Kukonzekera kofunikira kwa dera lolakwika la PCM/ECM lowongolera magetsi kungaphatikizepo:

• Kukonza mabwalo amfupi kapena ma terminals oyipa kapena kugwirizana
• Powertrain Control Module Relay Replacement
• Kusintha chipinda cha injini (block fuses)
• Kusintha zingwe za batri ndi/kapena zolumikizira
• Kuchotsa lama fuyusi

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P0685

Ichi ndi chimodzi mwa zizindikiro zomwe zingakhale zophweka kwambiri, monga batri yoipa kapena zingwe za batri, kapena zovuta kwambiri ndipo zimafuna ma tweaks ochepa ndi kukonzanso. Nthawi zonse funani thandizo la akatswiri m'dera lomwe simukulidziwa kuti mupewe kuwonongeka kwina kapena kusintha magawo okwera mtengo omwe angagwiritsidwe ntchito.

P0685 ✅ ZIZINDIKIRO NDI KUTHETSA ZOYENERA ✅ - Khodi yolakwika OBD2

Mukufuna thandizo lina ndi nambala yanu ya p0685?

Ngati mukufunabe thandizo ndi DTC P0685, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
