P0687 ECM/PCM amandla edluliselwe control circuit iphezulu

I-P0687 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Izinga lesignali ephezulu kusekethi yokulawula ukudluliselwa kwamandla kwe-ECM/PCM

Isho ukuthini ikhodi yephutha P0687?

Le Khodi Yenkinga Yokuxilonga (i-DTC) iyikhodi ejwayelekile yokudlulisa esebenza kuzo zonke izimoto ezakhiwa ngo-1996 (VW, BMW, Chrysler, Acura, Audi, Isuzu, Jeep, GM, njll.). Ibonisa i-voltage ephezulu etholwe yimojuli yokulawula i-powertrain (PCM) noma ezinye izilawuli kusekethe enikeza amandla ku-PCM noma kusekethe abanye abalawuli abaqapha i-PCM supply voltage.

Ukuqinisekisa ukusebenza okufanele, i-PCM kufanele ithole ukugeleza kwamandla okungashintshi ukusuka ebhethrini ngokusebenzisa i-relay yokuxhumana. Uma i-voltage esuka kubhethri ngokusebenzisa lokhu kudluliselwa iba phezulu kakhulu, i-PCM izosetha ikhodi engu-P0687 bese ivula ukukhanya kwenjini yokuhlola. Le nkinga ingenzeka ngenxa ye-relay engalungile noma izinkinga ze-voltage kusekethe.

Kubalulekile ukuqaphela ukuthi nakuba ikhodi ye-P0687 ivamile kuzo zonke izinhlobo zezimoto, izimbangela zingahluka kancane kuye ngomkhiqizi kanye nomklamo wenjini.

Izizathu ezingenzeka

Izizathu ezingaba khona zokusetha le khodi:

• Ijeneretha ingase igcwale kakhulu.
• Ukudluliselwa kwamandla kwe-PCM okungalungile.
• Amaswishi okubasa angalungile.
• Izintambo ezifushane noma izixhumi zezintambo.

Yiziphi izimpawu zekhodi yephutha? P0687?

Ikhodi P0687 ngokuvamile ayibangeli injini ukuthi ihluleke ukuqalisa, kodwa kwezinye izimo ingabangela i-PCM ukuthi izicime. Nakuba imoto ingase iqale futhi ibonakale isebenza, amandla kagesi angaphezulu angalimaza i-PCM nezinye izilawuli. Le khodi idinga ukunakwa ngokushesha.

Ukubona inkinga, kubalulekile ukwazi izimpawu zayo. Nazi ezinye izimpawu eziyinhloko zekhodi ye-OBD P0687:

• Kunzima ukuqala injini noma ungayiqalisi.
• Amandla enjini ancishisiwe kanye nokusheshisa.
• Injini ayisebenzi kahle.
• Hlola Ukukhanya Kwenjini Yokuhlola.

Ezimweni eziningi, Ukukhanya Kwenjini Yokuhlola kuzoba ukuphela kophawu lwekhodi ye-P0687. Nokho, ngezinye izikhathi isimo singase senzeke lapho injini ingeke iqale ukuvimbela umonakalo ku-PCM.

Indlela yokuxilonga ikhodi yephutha P0687?

Ukuze uhlonze ikhodi ye-P0687, qala ngokubheka amanqampunqampu esevisi yezobuchwepheshe (ama-TSB) emoto yakho. Lokhu kungonga isikhathi nemali njengoba abakhiqizi kungenzeka ukuthi sebeyayazi inkinga futhi bayilungise. Okulandelayo, hlola amahhanisi ezintambo, izixhumi, nezingxenye zesistimu ngomonakalo obonakalayo. Naka ijeneretha ukuze uqiniseke ukuthi ayilayishiwe kakhulu. Futhi hlola iziphetho zebhethri nekhebula lebhethri ukugqwala nokuxega.

Ukuze uhlole kahle ikhodi ye-P0687, uzodinga ithuluzi lokuskena le-OBD-II, imitha yedijithali ye-volt/ohm (DVOM), kanye nomdwebo wezintambo. Isithwebuli sizokusiza ukuthi uthole amakhodi amaphutha agciniwe. Bese usebenzisa imidwebo yezintambo namaphinikhodi wesixhumi ukuze uhlole i-PCM power relay kanye nokuxhumana kwayo. Hlola i-voltage kumatheminali afanelekile naphansi.

Uma i-generator isebenza ngendlela efanele futhi zonke izintambo zihlelekile, qhubeka nokuhlola amasekhethi ama-short circuits. Qaphela ukunqamula izilawuli kumahhanisi ezintambo ngaphambi kokuhlola ukumelana ne-DVOM. Uma kutholakala amasekethe amafushane, kufanele alungiswe noma ashintshwe.

Uma futhi unekhodi yokushajwa kwe-alternator, xazulula inkinga yayo ngaphambi kokukhuluma no-P0687. Khumbula ukuthi lapho ushintsha ama-relay, sebenzisa kuphela ama-relay anezinombolo ezifanayo. Ngemva kokukhanda ngakunye, sula amakhodi bese uhlola ukuze ubone ukuthi asethiwe futhi.

Amaphutha okuxilonga

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0687

Iphutha elilodwa elijwayelekile lapho uxilonga ikhodi ye-P0687 ukucabanga ngokushesha ukuthi i-PCM idinga ukushintshwa ukuze imoto ibuyele endleleni. Nokho, ukuthatha lesi sinyathelo ngaphandle kokuhlonza nokubhekana nembangela yangempela ye-P0687 kungaba yindleko futhi kungasebenzi. Ukuhlola okuphelele nokuxilongwa kungasindisa isikhathi esiningi, umzamo kanye nezinsiza ngokuhlonza ngokunembile futhi kuxazululwe inkinga. Khumbula ukuthi ukuxilonga okuningiliziwe kuyisihluthulelo sokuxazulula inkinga ngempumelelo.

Ibucayi kangakanani ikhodi yephutha? P0687?

Ikhodi P0687 ingaba nemiphumela emibi kakhulu kuye ngesimo sakho esithile. Uma kubangela ukuthi imoto ingaqali, kufanele ilungiswe inkinga ngaphambi kokuba imoto ishayelwe. Ngisho noma imoto isaqala, kubalulekile ukuqonda ukuthi amandla kagesi amaningi asetshenziswa ku-PCM angalimaza kakhulu lesi silawuli. Ngakho-ke, uma inkinga ihlala isikhathi eside ingaxazululiwe, ingozi enkulu yokuyilungisa izodinga ukushintshwa okuphelele kwe-PCM, okungaba inqubo ebizayo. Ngakho-ke, kubalulekile ukuthatha izinyathelo zokuxilonga nokuxazulula ikhodi ye-P0687 ngokushesha ngangokunokwenzeka ukuze ugweme izinkinga ezinkulu kakhulu.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0687?

Kunezinyathelo ezimbalwa zokulungisa ezingasiza ukuxazulula inkinga ehambisana nekhodi ye-P0687. Nazi ezinye zazo:

1. Lungisa noma shintsha i-alternator kanye/noma izintambo ezihambisanayo nezixhumi. Izinkinga nge-alternator zingabangela i-voltage ngokweqile, okuholela kukhodi ye-P0687. Hlola isimo se-generator nezingxenye zayo, kanye noxhumo lwezintambo.
2. Ukushintsha iswishi yokuthungela. Ukukhubazeka kumshini wokushisa kungabangela ikhodi yenkathazo P0687. Zama ukushintsha iswishi yokushisa futhi uqiniseke ukuthi isebenza kahle.
3. Ukushintsha i-PCM power relay. Uma i-PCM power relay ingasebenzi kahle, ingase ibangele inkinga ye-voltage ephezulu. Zama ukushintsha lesi dluliseli ufake esisha futhi uqiniseke ukuthi sisebenza ngendlela efanele.
4. Lungisa noma shintsha izintambo ezingalungile noma izixhumi phakathi kwebhethri, i-PCM power relay kanye ne-PCM ngokwayo. Izintambo nezixhumi zingalimala noma zigqwale, okungadala izinkinga zikagesi. Hlola isimo sabo futhi, uma kunesidingo, buyisela noma ushintshe.

Ukukhethwa kwesenzo esithile sokulungisa kuncike emiphumeleni yokuxilonga kanye nezinkinga ezitholakele. Lapho kulungiswa, kubalulekile ukulandela izincomo zochwepheshe futhi, uma kunesidingo, uthintane nomakhenikha noma uchwepheshe we-electronics.

Iyini Ikhodi Yenjini ye-P0687 [Umhlahlandlela osheshayo]

P0687 - Ulwazi oluthize lomkhiqizo

Ikhodi P0687 - Ukungasebenzi kukagesi kwesistimu yamandla ye-PCM (Powertrain Control Module). Le khodi ingasetshenziswa ezinhlobonhlobo zezimoto. Ukuze uhlole ngokunembile futhi uchaze leli phutha, kunconywa ukuthi uxhumane nochwepheshe noma abanikazi bezinhlobo zezimoto ezifanele. Umkhiqizi ngamunye angase abe nezici zakhe kanye nokucaciswa okuhlotshaniswa nale khodi.
