Isho ukuthini ikhodi yephutha P0685?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto zango-1996 (iHonda, VW, Ford, Dodge, Chrysler, Acura, Audi, GM, njll.).

Ngaphandle kohlobo lwazo olujwayelekile, izinjini ziyehluka phakathi kwemikhiqizo futhi zingaba nezizathu ezihluke kancane zale khodi.

Kokuhlangenwe nakho kwami ​​siqu, isimo sokuqala se-inhibit kungenzeka sihambisane nekhodi engu-P0685. Lapho le khodi igcinwa kumodyuli yokulawula i-powertrain (PCM), kusho ukuthi kutholakale i-voltage ephansi noma engekho esifundeni enikezela amandla we-battery ku-PCM.

Izimoto eziningi ezihlome nge-OBD-II zisebenzisa i-relay ukunikeza amandla kagesi ebhethri ku-PCM, kuyilapho ezinye zisebenzisa isekethe ehlanganisiwe kuphela. Ukudluliselwa kuvame ukuba nomklamo wamaphini amahlanu. Itheminali yokufaka eyinhloko ithola amandla kagesi ebhethri le-DC, itheminali ephansi isekelwe enjinini noma endaweni ye-chassis, itheminali yokufaka yesibili ithola i-voltage yebhethri (ngesekhethi ehlanganisiwe) lapho inkinobho yokuvutha ibekwe endaweni ethi "VULIWE". Itheminali yesine iwukukhiphayo kwe-PCM, kanti itheminali yesihlanu iyintambo yesiginali yenethiwekhi yesilawuli (CAN).

Lapho inkinobho yokushisa isesimweni se- "ON", i-voltage isetshenziswa kwikhoyili encane ngaphakathi kokudluliswa. Lokhu kuholela ekuvaliwe koxhumana nabo ngaphakathi kokudluliswa; ngokuqedela isekethe, ngaleyo ndlela kuhlinzekwe amandla ebhethri esigungwini sokukhipha bese ku-PCM.

Izimpawu

Njengoba ikhodi ye-P0685 imvamisa ihambisana nesimo sokuqala se-inhibit, ukungayinaki akunakwenzeka ukuthi kube inketho. Uma le khodi ikhona futhi injini iqala ukusebenza, sola i-PCM enephutha noma iphutha lohlelo lwe-PCM.

Isibani se-Check Engine singase sikhanyise, nakuba imoto kungenzeka isasebenza. Kuye ngokuthi inkinga ikuphi, imoto ingase iqale kodwa ingaqali, noma iqale kodwa amandla anciphile - noma ihambe ngendlela "exhugela".

Izinkinga ze-DTC P0685

Njenganoma iyiphi i-DTC, kungaba nezimbangela eziningi ezingaba khona. Okunye okuvame kakhulu ukudluliswa kwe-PCM okuyiphutha. Amanye amathuba ahlanganisa i-fuse eshaywayo, isifunda esifushane, uxhumano olubi, izinkinga zebhethri njengekhebula elingasebenzi kahle, futhi, ezimweni ezingavamile, i-PCM embi noma i-ECM.

Izizathu ezingaba khona zokusetha le khodi:

• Ukudluliswa kwamandla kwe-PCM okungalungile
• Fuse noma fuse kushaywa.
• Izixhumi ezincibilikisiwe noma ezilimele noma ezixhuma izintambo (ikakhulukazi edluliselwe ku-PCM)
• Inkinobho yokushisa engaphelele
• Ingxenye kagesi noma inqanyulwe ngokuphelele esigungwini sokushisa
• Ikhebuli yebhethri elahlekile noma elonakalisiwe iyaphela
• Ibhethri eliphansi
• I-voltage ephansi ekuqaleni
• I-Faulty Engine Control Module (ECM) Power Relay
• Ihhanisi lokudlulisa amandla e-ECM livuliwe noma lifushane.
• Isekhethi yamandla ye-ECM embi
• I-ECU fuse ishaywa
• I-ECM engasebenzi kahle Kusho ukuthini lokhu?

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Njengamanye amakhodi amaningi alolu hlobo, qala ukuxilongwa kwakho ngokubheka ngokubuka ama-harnesses we-wiring, izixhumi, kanye nezinto zohlelo. Naka kakhulu ukuthunyelwa okungavikelekile okungenzeka kuphume kumatheminali abo noma kungaba nezinyawo noma amatheminali abhubhisayo. Lokhu kubonakala ikakhulukazi lapho isikhungo sokudlulisa noma sokunethezeka siseduze nebhethri noma idamu lokupholisa. Bheka ukuthi ikhebula lebhethri nebhethri liphela kanjani ukuqina nokugqwala ngokweqile. Lungisa noma shintsha ukukhubazeka lapho kudingeka.

Uzodinga isithwebuli (noma umfundi wekhodi), i-digital volt / ohmmeter (i-DVOM), nomdwebo wiring. Imidwebo yokuxhuma ingatholakala kumenzi (ibhukwana lensizakalo noma okulinganayo) noma ngomthombo wesibili onjenge-All Data. Ngaphambi kokuthenga ibhukwana lensizakalo, qiniseka ukuthi liqukethe umdwebo wokuxhuma wesekethe yamandla we-PCM.

Ngaphambi kokuqhubeka nokuxilongwa, ngithanda ukubuyisa wonke ama-DTC agciniwe (ngisebenzisa iskena noma isifundi sekhodi) bese ngiwabhala phansi ukuze ngisetshenziswe esikhathini esizayo uma kudingeka. Ngingathanda futhi ukuqaphela noma iyiphi idatha yozimele efriziwe. Lolu lwazi lungasiza kakhulu uma inkinga okukhulunywa ngayo ivela ngezikhathi ezithile.

Ukuqala ngokudluliswa kwamandla (kwe-PCM), qiniseka ukuthi kukhona amandla ebhethri endaweni yokugcina yokufaka eyinhloko. Bheka umdwebo wiring, uhlobo lwesixhumi, noma i-pinout kusuka kwincwajana yakho yesevisi (noma okulingana nayo) ukuthola indawo yokugcina ngayinye. Uma ungekho ugesi, sola uxhumano olungalungile ku-fuse noma isixhumanisi se-fusible.

Bese uhlola ukuphela kokufaka kwesibili. Uma ungekho ugesi, sola i-fuse ephephukile noma iswishi yokuchema engalungile (ugesi).

Manje hlola isignali yomhlabathi. Uma kungekho siginali yomhlabathi, hlola izizathu zesistimu, izixhumi ze-wire harness bulk, i-chassis ground, nekhebula lebhethri liphela.

Uma wonke la masekethe elungile, hlola amandla okukhipha kumasekethe ahambisa amandla ku-PCM. Uma la masekethe engenawo amandla, sola i-relay engalungile.

Uma kukhishwa amandla kagesi, hlola amandla wesistimu kusixhumi se-PCM. Uma kungekho voltage ekhona, qala ukuhlola uhlelo lwezintambo. Qiniseka ukuthi unqamula abalawuli bohlelo kusuka ku-harness ngaphambi kokuhlola ukumelana ne-DVOM. Lungisa noma shintsha amasekethe avulekile noma afushane lapho kudingeka.

Uma kune-voltage ku-PCM, sola ukuthi inephutha noma inephutha lohlelo.

• Izinkomba ze "switch switch" kuleli cala zibhekisa engxenyeni kagesi kuphela.
• Ukufaka okunye ukudluliswa okufanayo (izinombolo ezifanayo) kokuhlolwa kungasiza kakhulu.
• Njalo setha kabusha ukudlulisela endaweni yayo yoqobo ngokufaka okusha ngokudluliselayo.
• Lapho uhlola uhlelo lwamafusi, qiniseka ukuthi isifunda sinamandla amakhulu.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0685

Njengoba le khodi ixhunywe kunethiwekhi eyinkimbinkimbi yezingxenye zikagesi, kulula ukugijimela esinqumweni futhi umane ubeke esikhundleni se-PCM, nakuba lokhu ngokuvamile akuyona inkinga futhi kudinga ukulungiswa okubizayo. Izintambo zebhethri ezigqwalile noma ukuxhumana okubi ngokuvamile kubangele izinkinga nge-PCM edluliselwe, ngakho kufanele kube yingxenye evamile yokuhlolwa.

Ibucayi kangakanani ikhodi ye-P0685?

Ngisho noma imoto yakho isebenza uma le khodi isethiwe, ingase ime noma yenqabe ukuqala noma kunini. Izingxenye zokuphepha ezibalulekile nazo zingathinteka - isibonelo, izibani zakho zingacisha ngokuzumayo, okungaba yingozi uma ushayela ebusuku uma lokhu kwenzeka. Uma uhlangabezana nezimpawu zenkinga, njengomsakazo ongasebenzi, kufanele uxhumane nochwepheshe ukuze uxilonge futhi ulungise inkinga ngokushesha ngangokunokwenzeka ukuze ugweme ukulimala okwengeziwe kwezinye izingxenye.

Yiziphi izilungiso ezingalungisa ikhodi P0685?

Ukulungiswa okudingekayo kumjikelezo wokulawula ukudluliselwa kwamandla we-PCM/ECM okungalungile kungase kuhlanganise:

• Ukulungisa amasekhethi amafushane noma amatheminali amabi noma izixhumanisi
• I-Powertrain Control Module Relay Replacement
• Ukushintsha indawo yenjini (block amafyuzi)
• Ukushintsha izintambo zebhethri kanye/noma izixhumi
• Esikhundleni fuse

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0685

Lena enye yalawo makhodi angaba lula kakhulu, njengebhethri elibi noma izintambo zebhethri, noma inkimbinkimbi futhi idinga ama-tweaks ambalwa nokulungiswa. Ngaso sonke isikhathi funa usizo oluchwepheshile endaweni ongayijwayele ukuze ugweme omunye umonakalo noma ukushintshwa kwezingxenye ezibizayo ezingase zisebenze.

Udinga usizo olwengeziwe ngekhodi le-p0685?

Uma usadinga usizo nge-DTC P0685, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
