P0687 ECM/PCM fais fab relay tswj Circuit Court siab

P0687 – OBD-II Teeb meem Code Technical Description

Siab teeb liab theem hauv ECM / PCM fais fab relay tswj Circuit Court

Qhov txhaum cai txhais li cas P0687?

No Diagnostic Trouble Code (DTC) yog ib tug generic kis code uas siv rau tag nrho cov tsheb tsim nyob rau hauv 1996 (VW, BMW, Chrysler, Acura, Audi, Isuzu, Jeep, GM, thiab lwm yam). Nws qhia tau hais tias muaj hluav taws xob siab pom los ntawm powertrain control module (PCM) los yog lwm yam controllers ntawm lub Circuit Court uas muab lub zog rau PCM los yog nyob rau hauv Circuit Court uas lwm yam controllers saib lub PCM mov voltage.

Txhawm rau kom ua haujlwm tau zoo, PCM yuav tsum tau txais lub zog tas li ntawm lub roj teeb los ntawm kev sib cuag relay. Yog tias qhov hluav taws xob los ntawm lub roj teeb los ntawm qhov relay dhau los ua qhov siab dhau lawm, PCM yuav teeb tsa P0687 code thiab qhib lub teeb lub cav. Qhov teeb meem no tuaj yeem tshwm sim vim muaj teeb meem relay lossis teeb meem voltage hauv Circuit Court.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum lub P0687 code yog muaj nyob rau hauv ntau yam ntawm cov tsheb, qhov ua rau yuav txawv me ntsis nyob ntawm seb cov chaw tsim khoom thiab lub cav tsim.

Tej zaum ua rau

Qhov laj thawj ua rau teeb tsa cov cai no:

• Lub tshuab hluav taws xob tuaj yeem ua rau overloaded.
• Faulty PCM fais fab relay.
• Faulty ignition keyboards.
• Cov kab hluav taws xob luv luv lossis cov kab txuas txuas.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0687?

Code P0687 feem ntau tsis ua rau lub cav tsis ua haujlwm, tab sis qee zaum nws tuaj yeem ua rau PCM lov tes taw nws tus kheej. Txawm hais tias lub tsheb tseem tuaj yeem pib thiab tshwm sim ua haujlwm, qhov hluav taws xob ntau dhau tuaj yeem ua mob rau PCM thiab lwm yam kev tswj hwm. Txoj cai no yuav tsum tau saib xyuas tam sim ntawd.

Txhawm rau txheeb xyuas qhov teeb meem, nws yog ib qho tseem ceeb kom paub nws cov tsos mob. Nov yog qee cov tsos mob tseem ceeb ntawm OBD code P0687:

• Nyuaj pib lub cav lossis tsis pib nws.
• Txo lub cav lub zog thiab acceleration.
• Cav misfiring.
• Tshawb xyuas Lub Teeb Tsav Tsheb.

Feem ntau, Lub Teeb Tsav Tsheb yuav tsuas yog cov tsos mob ntawm tus lej P0687. Txawm li cas los xij, qee zaum muaj xwm txheej tshwm sim uas lub cav yuav tsis pib tiv thaiv kev puas tsuaj rau PCM.

Yuav ua li cas kuaj tau tus lej txhaum P0687?

Txhawm rau txheeb xyuas tus lej P0687, pib los ntawm kev tshuaj xyuas cov ntawv xov xwm kev pabcuam (TSBs) rau koj lub tsheb. Qhov no tuaj yeem txuag lub sijhawm thiab nyiaj txiag txij li cov tuam txhab lag luam tuaj yeem paub qhov teeb meem thiab kho nws. Tom ntej no, xyuas cov hlua khi, cov khoom sib txuas, thiab cov khoom siv hauv lub cev kom pom kev puas tsuaj. Ua tib zoo mloog rau lub tshuab hluav taws xob kom paub tseeb tias nws tsis yog overloaded. Kuj xyuas lub roj teeb thiab roj teeb cable xaus rau corrosion thiab looseness.

Txhawm rau kuaj pom tus lej P0687 kom raug, koj yuav xav tau OBD-II scan tool, digital volt / ohm meter (DVOM), thiab daim duab thaiv. Lub scanner yuav pab koj khaws cov lej yuam kev. Tom qab ntawd siv cov kab kos thiab cov pinouts txuas los xyuas PCM fais fab relay thiab nws cov kev sib txuas. Xyuas qhov voltage ntawm qhov tsim nyog terminals thiab hauv av.

Yog tias lub tshuab hluav taws xob ua haujlwm raug thiab tag nrho cov xaim nyob rau hauv kev txiav txim, mus xyuas cov circuits rau luv circuits. Ceev faj kom tsis txhob cuam tshuam cov maub los ntawm cov hlua khi ua ntej kuaj xyuas nrog DVOM. Yog tias kuaj pom qhov luv luv, lawv yuav tsum tau kho lossis hloov.

Yog tias koj tseem muaj tus lej hloov pauv nyiaj dhau, daws nws qhov teeb meem ua ntej hais txog P0687. Nco ntsoov tias thaum hloov cov relays, tsuas yog siv cov relays nrog cov lej sib npaug. Tom qab txhua qhov kho, tshem cov lej thiab xyuas seb lawv puas tau teeb tsa dua.

Kev kuaj mob yuam kev

COMMON yuam kev thaum kuaj xyuas tus lej P0687

Ib qho yuam kev thaum kuaj pom tus lej P0687 yog xav tau sai heev uas PCM yuav tsum tau hloov pauv kom lub tsheb rov qab mus. Txawm li cas los xij, ua cov kauj ruam no yam tsis tau txheeb xyuas thawj zaug thiab hais txog qhov tseeb ntawm P0687 tuaj yeem raug nqi thiab tsis muaj txiaj ntsig. Kev tshuaj xyuas thiab kev kuaj mob kom zoo tuaj yeem txuag tau ntau lub sijhawm, kev siv zog thiab peev txheej los ntawm kev txheeb xyuas thiab daws qhov teeb meem kom raug. Nco ntsoov tias kev kuaj mob kom ntxaws yog tus yuam sij rau kev daws teeb meem zoo.

Txoj cai txhaum loj npaum li cas? P0687?

Code P0687 tuaj yeem muaj qhov tshwm sim loj nyob ntawm koj qhov xwm txheej tshwj xeeb. Yog tias nws ua rau lub tsheb tsis pib, qhov teeb meem yuav tsum tau kho ua ntej lub tsheb tuaj yeem tsav tau. Txawm hais tias lub tsheb tseem pib, nws yog ib qho tseem ceeb kom nkag siab tias qhov hluav taws xob ntau dhau siv rau PCM tuaj yeem ua rau tus maub los no puas tsuaj. Yog li ntawd, qhov ntev ntawm qhov teeb meem tseem tsis tau daws, qhov kev pheej hmoo ntau dua uas kho nws yuav xav tau kev hloov PCM tiav, uas tuaj yeem yog cov txheej txheem kim. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau ua cov kauj ruam los ntsuam xyuas thiab daws P0687 chaws kom sai li sai tau kom tsis txhob muaj teeb meem loj dua.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0687?

Muaj ob peb kauj ruam kho uas tuaj yeem pab daws qhov teeb meem cuam tshuam nrog P0687 code. Nov yog qee qhov ntawm lawv:

1. Kho los yog hloov lub alternator thiab / los yog txuam cov hlua thiab connectors. Teeb meem nrog lub alternator tuaj yeem ua rau muaj hluav taws xob ntau dhau, uas ua rau P0687 code. Txheeb xyuas qhov xwm txheej ntawm lub tshuab hluav taws xob thiab nws cov khoom siv, nrog rau kev sib txuas ntawm cov xov hlau.
2. Hloov lub ignition hloov. Qhov tsis xws luag hauv qhov hloov hluav taws xob tuaj yeem ua rau muaj teeb meem code P0687. Sim hloov qhov hloov hluav taws xob thiab xyuas kom nws ua haujlwm kom raug.
3. Hloov lub PCM fais fab relay. Yog tias PCM fais fab relay tsis ua haujlwm zoo, nws yuav ua rau muaj teeb meem hluav taws xob siab. Sim hloov qhov relay no nrog ib qho tshiab thiab xyuas kom nws ua haujlwm kom raug.
4. Kho lossis hloov cov xov hlau tsis raug lossis cov khoom sib txuas ntawm lub roj teeb, PCM fais fab relay thiab PCM nws tus kheej. Cov hlua hluav taws xob thiab cov khoom sib txuas yuav raug puas los yog corroded, uas tuaj yeem ua rau muaj teeb meem hluav taws xob. Xyuas lawv tus mob thiab, yog tias tsim nyog, rov qab los yog hloov.

Kev xaiv ntawm ib qho kev kho tshwj xeeb yog nyob ntawm qhov kev kuaj mob thiab cov teeb meem pom. Thaum ua kev kho, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus pom zoo ntawm cov kws tshaj lij thiab, yog tias tsim nyog, sab laj nrog kws kho tsheb lossis kws tshaj lij hluav taws xob.
