Bayanan Bayani na OBD-II

Babban matakin siginar shigarwa a cikin sarkar firikwensin matsayi na bawul ɗin malam / pedal / canza "E"

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. Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Lokacin da na ci karo da lambar da aka adana P2128, na gano cewa yana nufin tsarin kula da wutar lantarki (PCM) ya gano babban shigar da wutar lantarki daga da'irar Maɓallin Matsayi (TPS) ko takamaiman da'irar Matsayin Matsayi (PPS). Harafin "E" yana nufin takamaiman da'irar, firikwensin, ko yanki na takamaiman da'ira.

Koma zuwa tushen amintaccen bayanin abin hawa (duk bayanan DIY zasuyi aiki) don cikakkun bayanan abin hawa da ake tambaya. Ana amfani da wannan lambar ne kawai a cikin motocin da aka sanye da tsarin tuƙi-ta waya (DBW).

PCM ɗin yana sarrafa tsarin DBW ta amfani da matattarar matattara, ɗaya ko fiye na firikwensin matsayin kafa (wani lokacin ana kiranta firikwensin matsayin ƙwallon ƙafa), da firikwensin matsayi mai yawa. Na'urorin firikwensin suna da ƙarfin lantarki (yawanci 5 V) da ƙasa. Yawancin firikwensin TPS / PPS na nau'in potentiometer ne kuma suna kammala madaidaicin da ya dace. Extensionaukar ƙaramar gatari mai ɗorewa akan ƙafar hanzari ko akan maƙerin maƙallan yana kunna lambobin firikwensin. Canjin firikwensin yana canzawa yayin da fil ɗin ke motsawa a cikin PCB mai firikwensin, yana haifar da canje -canje a juriya na kewaye da siginar shigar da siginar zuwa PCM.

Idan ƙarfin siginar shigarwa ya wuce iyakar da aka tsara, na tsawan lokaci da ƙarƙashin wasu yanayi, za a adana lambar P2128 kuma Lamp Indicator Lamp (MIL) na iya haskakawa.

Alamun / tsananin

Lokacin da aka adana wannan lambar, PCM galibi yana shiga gurgu. A cikin wannan yanayin, hanzarin injin zai iyakance sosai (sai dai idan naƙasasshe). Alamomin lambar P2128 na iya haɗawa da:

• Maƙura maƙil (a kowane rpm)
• Ƙuntataccen hanzari ko babu hanzari
• Injin yana tsayawa yayin bacci
• Oscillation akan hanzari
• Gudanar da jirgin ruwa ba ya aiki

Mai yiwuwa sanadin wannan lambar injin ya haɗa da:

• Buɗewa ko gajere kewaye a cikin sarkar tsakanin TPS, PPS da PCM
• TPS mara kyau ko PPS
• Gurbatattun masu haɗin lantarki
• M mota mai sarrafa madogara

Hanyoyin bincike da gyara

Kyakkyawan farawa shine koyaushe bincika takaddun sabis na fasaha (TSB) don takamaiman abin hawa. Matsalar ku na iya zama sanannen batun tare da sanannen gyaran masana'anta kuma yana iya adana ku lokaci da kuɗi yayin bincike.

Zan isa ga na'urar binciken na’ura, volt / ohmmeter na dijital (DVOM), da tushen bayanan abin hawa kamar Duk Bayanai (DIY) don gano lambar P2128.

Zan ɗauki matakin farko na ganewar asali ta hanyar duba duk wayoyi da masu haɗin haɗin da ke da alaƙa da tsarin. Ina kuma son duba jikin maƙura don alamun ƙirar carbon ko lalacewa. Haɗin carbon da ya wuce kima wanda ke sa jikin maƙura ya buɗe yayin farawa na iya haifar da adana lambar P2128. Tsaftace duk wani ajiyar carbon daga jikin maƙura bisa ga shawarwarin masana'anta kuma gyara ko maye gurbin wayoyi mara kyau ko aka gyara kamar yadda ya cancanta, sannan sake gwada tsarin DBW.

Sannan na haɗa na'urar daukar hotan takardu zuwa tashar binciken abin hawa kuma in dawo da duk DTC da aka adana. Na rubuta shi kawai idan ina buƙatar tsari wanda aka adana lambobin a ciki. Ina kuma son in adana duk wani bayanan daskarewa da ke da alaƙa. Waɗannan bayanan na iya zama da taimako idan P2128 ya zama na ɗan lokaci. Yanzu ina share lambobin kuma gwaji na tuka motar. Idan an share lambar, na ci gaba da tantancewa

Ana iya gano ƙarfin wutar lantarki da rashin daidaituwa tsakanin TPS, PPS da PCM ta amfani da rafin bayanan na'urar daukar hotan takardu. Kunkuntar da bayanan ku don nuna bayanai masu dacewa kawai don amsawa da sauri. Idan ba a sami spikes da / ko rashin daidaituwa ba, yi amfani da DVOM don samun bayanai na ainihi daga kowane firikwensin daban. Don samun bayanai na ainihi ta amfani da DVOM, haɗa gwajin yana kaiwa ga siginar da ta dace da da'irar ƙasa da lura da nuni na DVOM yayin da DBW ke gudana. Lura ƙarfin lantarki yana ƙaruwa yayin sannu a hankali yana motsa bawul ɗin maƙera daga rufe zuwa cikakken buɗewa. Yawan wutar lantarki yawanci yana daga 5V rufe maƙura zuwa 4.5V m bude maƙura. Idan an sami surges ko wasu munanan halaye, yi zargin cewa firikwensin da ake gwadawa yana da lahani. Oscilloscope shima babban kayan aiki ne don tabbatar da aikin firikwensin.
