Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take. Wannan na iya haɗawa, amma ba'a iyakance shi ba, Ford, Chevrolet, Honda, da dai sauransu Yayin janar, takamaiman matakan gyara na iya bambanta dangane da iri / ƙirar.

Idan abin hawa na OBD-II yana da lambar da aka adana P06A7, yana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano siginar siginar siginar waje ko matsala tare da takamaiman firikwensin da aka yiwa lakabi da "B". Mai firikwensin da ake tambaya galibi yana da alaƙa da watsawa ta atomatik, yanayin canja wuri, ko ɗayan bambance -bambancen.

Ƙarin takamaiman lambar firikwensin kusan koyaushe yana tare da wannan lambar. P06A7 yana ƙara da cewa ƙarfin siginar siginar firikwensin baya cikin iyaka ko ana tsammanin. Don tantance wuri da aikin firikwensin “B” don abin hawa abin tambaya, tuntuɓi amintaccen tushen bayanin abin hawa (misali AllDataDIY). Yi zargin akwai kuskuren shirye -shiryen PCM idan an adana P06A7 daban. Kuna buƙatar bincika da gyara duk wasu lambobin firikwensin kafin ganowa da gyara P06A7, amma ku kula da matsayin ƙarfin ƙarfin ƙarfin kewayo / aiki.

Ana ba da firikwensin da ake tambaya tare da ƙarfin lantarki (yawanci 5 V) ta hanyar juyawa (wanda aka kunna lokacin kunnawa). Hakanan za'a sami siginar ƙasa. Mai firikwensin zai kasance ko dai juriya mai canzawa ko nau'in electromagnetic kuma yana kammala kewaye. Yakamata juriya na firikwensin ya ragu tare da ƙara matsin lamba, zazzabi ko sauri, da akasin haka. Yayin da juriya na firikwensin ke canzawa (gwargwadon yanayi), yana ba PCM siginar siginar shigarwa.

Idan siginar ƙarfin shigarwar da PCM ta karɓa yana waje da sigogin da ake tsammanin, za a adana P06A7. Hakanan ana iya haska fitilar mai nuna rashin aiki (MIL). Wasu ababen hawa za su buƙaci hawan tuki da yawa (idan aka gaza) don fitilar faɗakarwa ta haskaka. Bari PCM ta shiga cikin yanayin shiri kafin ɗaukar ɗaukacin ya yi nasara. Kawai cire lambar bayan gyara kuma ku tuka motar al'ada. Idan PCM ya shiga cikin yanayin shiri, gyara ya yi nasara. Idan an share lambar, PCM ba zai shiga cikin yanayin jiran aiki ba kuma kun san laifin har yanzu yana nan.

Tsanani da alamu

Tsananin wannan DTC ya dogara ne akan da'irar firikwensin ke fuskantar ƙarancin wutar lantarki. Dole ne a sake duba wasu lambobin da aka adana kafin a yanke hukunci mai tsanani.

Alamomin lambar P06A7 na iya haɗawa da:

• Rashin iya canza watsawa tsakanin wasanni da yanayin tattalin arziki
• Gear canzawa malfunctions
• Jinkiri (ko rashin) na kunna watsawa
• Rashin watsawa don canzawa tsakanin XNUMXWD da XNUMXWD
• Rashin jakar canja wuri don sauyawa daga ƙananan zuwa babban kaya
• Rashin hadawa da bambancin gaban
• Rashin sa hannun cibiya ta gaba
• Ba daidai ba ne ko kuma baya aiki da ma'aunin sauri / odometer

Mai yiwuwa sanadin wannan lambar injin ya haɗa da:

• Mummunan firikwensin
• Fuses mara kyau ko busawa da / ko fuse
• Kuskuren tsarin wutar lantarki
• Buɗe kewaye da / ko masu haɗawa

Hanyoyin bincike da gyara

Binciken lambar P06A7 da aka adana zai buƙaci na'urar binciken cuta, volt / ohmmeter (DVOM) na dijital, da amintaccen tushen bayanan abin hawa (kamar Duk Bayanai na DIY). Hakanan oscilloscope na hannu zai iya taimakawa wajen yin ganewar asali.

Na farko, tuntuɓi tushen bayanan abin hawa don sanin wurin aiki da aikin firikwensin da ake tambaya kamar yadda ya keɓanta ga abin hawan ku. Duba ido da kayan doki da masu haɗin haɗin da ke da alaƙa da tsarin firikwensin. Gyarawa ko maye gurbin wayoyin da suka lalace ko ƙonewa, masu haɗawa, da abubuwan da ake buƙata kamar yadda ya cancanta. Abu na biyu, haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa kuma dawo da duk DTC da aka adana kuma daskare bayanan firam. Yi bayanin lambobin tare da tsarin da aka adana su da duk wani bayanan daskarewa mai dacewa, saboda wannan bayanin na iya zama da amfani idan lambar ta zama mai ɓata lokaci. Yanzu zaku iya ci gaba da tsaftace lambar; sannan gwada gwajin abin hawa don tabbatar an sake saita shi nan da nan.

Idan lambar ta sake farawa nan da nan, yi amfani da DVOM don gwada ƙarfin lantarki da siginar ƙasa akan firikwensin da ake tambaya. Yawanci zaku yi tsammanin samun 5 volts da ƙasa a mai haɗa firikwensin.

Ci gaba da gwada juriya na firikwensin da matakan ci gaba idan ƙarfin lantarki da siginar ƙasa suna nan a mai haɗa firikwensin. Sami takamaiman gwaji daga tushen bayanan abin hawan ku kuma kwatanta ainihin sakamakon ku da su. Sensors waɗanda basu cika waɗannan ƙayyadaddun bayanai ba ya kamata a maye gurbinsu.

Cire duk masu sarrafawa masu alaƙa daga da'irar tsarin kafin gwada juriya tare da DVOM. Rashin yin hakan na iya lalata PCM. Idan ƙarfin ƙarfin tunani ya yi ƙasa (a firikwensin), yi amfani da DVOM don gwada juriya da ci gaba tsakanin firikwensin da PCM. Sauya da'irori masu buɗewa ko gajarta kamar yadda ya cancanta. Idan firikwensin da ake tambaya shine na'urar firikwensin electromagnetic mai canzawa, yi amfani da oscilloscope don bin diddigin bayanai a cikin ainihin lokaci.

Kuna buƙatar ƙarin taimako tare da lambar P06A7?

Idan har yanzu kuna buƙatar taimako tare da DTC P06A7, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.
