ECM/PCM relay relay powered de-powered - too late

Mene ne wannan yake nufi?

Wannan sigar Lambar Matsalar Bincike ce (DTC) wacce ta dace da yawancin motocin OBD-II (1996 da sabuwa). Wannan na iya haɗawa amma ba'a iyakance ga Audi, Chrysler, Dodge, Jeep, Ram, Volkswagen, da dai sauransu Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da shekarar ƙirar, ƙirar, ƙirar da tsarin watsawa.

Lambar P068B da aka adana tana nufin tsarin sarrafa injin / powertrain (ECM / PCM) ya gano matsala a cire haɗin wuta zuwa relay ɗin da ke ƙarfafa shi. A wannan yanayin, komarwar wutar PCM baya ƙarfafawa da sauri.

Ana amfani da gudun ba da wutar lantarki na PCM don samar da wutar lantarki ta baturi lafiya zuwa da'irar PCM da suka dace. Wannan nau'in hanyar sadarwa ne wanda ke kunna ta wayar sigina daga maɓallin kunnawa. Dole ne a rage ƙarfin wannan na'urar a hankali a hankali don guje wa hawan wuta da yuwuwar lalacewa ga mai sarrafawa. Wannan nau'in relay yawanci yana da da'ira mai waya biyar. Ana ba da waya ɗaya tare da ƙarfin baturi akai-akai; kasa a daya. Da'irar ta uku tana ba da siginar daga maɓallin kunnawa, kuma na huɗu yana ba da wutar lantarki zuwa PCM. Waya ta biyar ita ce da'irar firikwensin wutar lantarki. PCM ke amfani dashi don saka idanu akan ƙarfin isar da wutar lantarki.

Idan PCM ya gano rashin aiki lokacin da aka kashe wutar ECM / PCM, za a adana lambar P068B kuma fitilar mai nuna rashin aiki (MIL) na iya haskakawa.

Menene tsananin wannan DTC?

Dole ne a rarrabe lambar P068B da mahimmanci kuma a magance ta daidai. Wannan na iya haifar da rashin iya farawa da / ko matsaloli daban -daban tare da sarrafa abin hawa.

Menene wasu alamomin lambar?

Alamomin lambar matsala P068B na iya haɗawa da:

An fara jinkiri ko a'a
Matsalolin baturi masu rauni ko marasa ƙarfi

Mene ne wasu abubuwan da ke haifar da lambar?

Dalilan wannan lambar na iya haɗawa da:

Menene wasu matakai don warware matsalar P068B?

Ana buƙatar na'urar binciken cuta da volt / ohmmeter na dijital (DVOM) don tantance lambar P068B.

Hakanan kuna buƙatar tushen ingantaccen bayani game da motocin. Yana ba da zane -zanen toshe bincike, zane -zanen wayoyi, fuskokin mai haɗawa, pinouts masu haɗawa, da wuraren abubuwan haɗin. Hakanan zaku sami hanyoyin da ƙayyadaddun abubuwa don gwajin abubuwan haɗin gwiwa da da'irori. Za a buƙaci duk wannan bayanin don samun nasarar tantance lambar P068B.

Haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa kuma sami duk lambobin da aka adana kuma daskare bayanan firam. Yi bayanin wannan bayanin saboda yana iya zama da amfani idan lambar ta zama ta katsewa.

Bayan yin rikodin duk bayanan da suka dace, share lambobin kuma gwada gwajin abin hawa (idan zai yiwu) har sai an share lambar ko PCM ta shiga yanayin shirye.

Idan PCM ya shiga cikin yanayin da aka shirya, lambar za ta kasance tsaka -tsaki har ma ta fi wahalar ganewa. Yanayin da ya haifar da dorewar P068B na iya buƙatar yin muni kafin a iya yin cikakken bincike. A gefe guda, idan ba za a iya share lambar ba kuma alamun kulawar ba su bayyana ba, ana iya tuka abin hawa yadda aka saba.

Tuntuɓi tushen bayanan abin hawa don bayanan sabis na fasaha (TSBs) waɗanda ke haifar da lambar da aka adana, abin hawa (shekara, kera, ƙirar da injin) da alamun da aka gano. Idan kun sami TSB da ta dace, zai iya ba da bayanan bincike masu amfani.

Idan lambar P068B ta sake farawa nan da nan, duba cikin wayoyi da masu haɗin haɗin da ke da alaƙa da tsarin. Belt ɗin da ya karye ko ya ɓace ya kamata a gyara ko musanya su idan an buƙata.

Idan wayoyi da masu haɗawa suna da kyau, yi amfani da tushen bayanan abin hawan ku don samun zane -zanen wayoyi masu alaƙa, ra'ayoyin fuskar mai haɗawa, zane -zanen pinout mai haɗawa, da zane -zanen toshe bincike.

Da zarar kun sami bayanan da kuke buƙata, bincika duk fuse da relays a cikin tsarin don tabbatar da cewa ana ba da ƙarfin batir zuwa komputa na wutar lantarki na PCM.

Samu sigogin kashe wutar PCM kuma amfani da su zuwa matakan bincike na gaba.

Idan babu DC (ko canzawa) ƙarfin lantarki a mai haɗawa da wutar lantarki, gano madaidaicin da'irar zuwa fuse ko relay daga inda ya fito. Gyara ko maye gurbin fuses ko fuse masu lahani kamar yadda ya cancanta.

Idan ƙarfin wutar lantarki mai ba da wutar lantarki da ƙasa suna nan (a duk tashoshin da suka dace), yi amfani da DVOM don gwada aikin fitowar relay a fil ɗin mai haɗawa da ya dace. Idan ƙarfin wutan fitarwa na mai ba da wutar lantarki bai cika buƙatun ba, yi zargin cewa relay ɗin ba daidai bane.

Idan wutar lantarki mai ba da wutar lantarki ta PCM tana cikin ƙayyadaddun (a duk tashoshi), duba madaidaicin fitowar fitowar wutar lantarki akan PCM.

Idan an gano siginar siginar wutan lantarki mai fitarwa a mahaɗin PCM, yi zargin kuskuren PCM ko kuskuren shirye -shiryen PCM.

Idan ba a sami siginar fitowar wutar lantarki ta PCM da ta dace akan mai haɗa PCM ba, yi zargin buɗe ko gajeriyar da'ira tsakanin komarwar wutar PCM da PCM.

Ya kamata a bincika fuskoki da fuse tare da da'irar da aka ɗora don gujewa kamuwa da cuta.
