Bayanan Bayani na OBD-II

Na'urar firikwensin abin hawa "B" Mai tsaka -tsaki / ɓarna / babba

Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk motocin 1996 (Ford, Dodge, GMC, Chevy, da sauransu). Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Lokacin da aka nuna lambar P2161, yana nufin tsarin kula da wutar lantarki (PCM) ya gano siginar shigar da wutar lantarki daga firikwensin saurin abin hawa (VSS) B wanda ke taɓarɓarewa, ɓarna, ko wuce kima. Nadin B yawanci yana nufin VSS na biyu a cikin tsarin da ke amfani da firikwensin saurin abin hawa da yawa.

Na'urorin firikwensin saurin abin hawa na OBD II gabaɗaya sune firikwensin electromagnetic waɗanda ke amfani da wani nau'in jet ko gearwheel wanda aka haɗe da injin a cikin gatari, watsawa / canja wurin shaft ɗin fitarwa, watsawa daban -daban, ko mashin tuƙi. Yayin da shaft ɗin ke jujjuyawa, zoben ƙarfe na reactor yana juyawa. Zobe na reactor ɗin yana kammala kewaya tare da firikwensin lantarki na tsaye yayin da reactor ke wucewa kusa da kusurwar electromagnetic na firikwensin. Ramin da ke tsakanin hakoran zobe na firikwensin yana haifar da fashewa a cikin da'irar firikwensin. Haɗin kammalawa da katsewa ana gane shi ta PCM (kuma mai yiwuwa wasu masu sarrafawa) azaman samfuran ƙirar ƙarfin lantarki.

PCM yana lura da saurin abin hawa ta amfani da shigarwa daga ɗaya ko fiye na firikwensin saurin abin hawa. PCM yana kwatanta shigarwar daga VSS tare da shigarwar Module Control Module Control (ABCM) ko Module Control Brake (EBCM). Ana iya shigar da shigarwar VSS na farko (B) ta hanyar VSS a cikin watsawa, amma shigarwar VSS na biyu ana iya sa ido ta hanyar ɗaya ko fiye na firikwensin saurin ƙafa.

Idan PCM ta gano siginar da ba ta dace ba, mai ɓarna ko babban siginar wutar lantarki daga VSS na farko, za a adana lambar P2161 kuma fitilar mai nuna rashin aiki na iya haskakawa. Ƙarfin da ba shi da ƙarfi, mara ƙarfi, ko babban ƙarfin lantarki na iya zama sakamakon matsalar lantarki ko na inji.

Ƙarfin lamba da alamu

Kamar yadda yanayin da zai iya haifar da dorewar lambar P2161 na iya haifar da tashin hankali da matsalolin ABS, yakamata a rarrabasu da mahimmanci kuma a magance su da wani matakin gaggawa.

Alamomin lambar P2161 na iya haɗawa da:

• Aiki mara daidaituwa na ma'aunin ma'aunin sauri / odometer
• Samfuran canzawa mara tsari
• Ana iya adana sauran watsawa da lambobin ABS
• Fitilar injin gaggawa, fitilar sarrafa gogayya ko fitilar tsarin kulle-kulle
• Kunna ba zato ba tsammani / kashe ikon sarrafa juyi (idan an sanye shi)
• A wasu halaye, tsarin ABS na iya kasawa.

dalilai

Dalili mai yiwuwa na wannan lambar:

• Yawan tara tarkace na ƙarfe a kan firikwensin sauri / s
• Motocin da ke da matsala ko firikwensin saurin abin hawa.
• Yanke ko in ba haka ba lalacewar wayoyi ko masu haɗawa (musamman kusa da firikwensin sauri)
• An lalace ko hakoran hakora akan zobe na reactor.
• PCM mai lahani, ABCM ko EBCM

Hanyoyin bincike da gyara

Zan buƙaci na'urar bincike, ɗigon dijital / ohmmeter (DVOM), mai yiwuwa oscilloscope da amintaccen tushen bayanan abin hawa don tantance lambar P2161. Na'urar daukar hotan takardu tare da ginanniyar DVOM da oscilloscope zai zama manufa don wannan ganewar.

Ina so in fara bincike tare da dubawar gani na tsarin wayoyi, firikwensin sauri, da masu haɗawa. Zan gyara da'irori masu buɗewa ko gajeru kamar yadda ake buƙata kuma in cire tarkacen ƙarfe da yawa daga firikwensin firikwensin. Idan cirewar firikwensin zai yiwu, zan kuma bincika amincin duk zoben reactor a wannan lokacin.

Sannan na haɗa na'urar daukar hotan takardu zuwa tashar binciken mota kuma na sami duk DTC da aka adana da daskare bayanan firam. Rubuta wannan bayanin saboda yana iya zama da taimako yayin ci gaba da binciken ku. Yanzu share lambobin kuma gwada fitar da abin hawa don ganin idan alamun sun ci gaba da / ko sharewa.

Dabarar da ƙwararrun ƙwararrun masana ke amfani da ita shine bincika tushen bayanan abin hawa don cikakkun bayanan sabis na fasaha (TSB). Idan kun sami TSB wanda ya dace da alamun da lambobin adana abin hawa da ake tambaya, bayanan binciken da ke ƙunshe yana iya taimakawa gano P2161 daidai.

Kula da saurin motar da / ko saurin abin hawa (ta amfani da rafin bayanan na'urar daukar hoto) yayin gwada abin hawa. Ta hanyar taƙaita rafin bayanai don nuna filayen da suka dace kawai, zaku iya haɓaka saurin da daidaiton isar da bayanan da kuke so. Rashin daidaituwa, rashin daidaituwa, ko babban karatu daga firikwensin VSS ko saurin dabaran na iya haifar da wayoyi, mai haɗa wutar lantarki, ko matsalolin firikwensin ta hanyar taƙaita yankin kuskuren tsarin gaba ɗaya.

Yi amfani da DVOM don yin gwajin juriya akan firikwensin da ake tambaya bayan kun nuna yankin matsalar. Duba tare da tushen bayanan abin hawan ku don shawarwarin masu ƙira don gwada VSS da maye gurbin firikwensin da ba a fayyace ba. Ana iya amfani da oscilloscope don samun bayanai na ainihi daga kowane mutum na VSS ta hanyar bincika siginar siginar firikwensin da wayar ƙasa. Dole ne watsawar ta kasance cikin tsari mai kyau, saboda haka za a buƙaci abin dogaro ko abin hawa don yin irin wannan gwajin cikin aminci.

Na'urorin firikwensin saurin abin hawa galibi suna lalacewa sakamakon gyaran watsawa na yau da kullun, kuma firikwensin saurin dabaran (da kayan haɗin wayoyi) galibi suna karya lokacin da aka gyara birki. Idan an nuna lambar P2161 (kai tsaye bayan gyara), yi zargin cewa kayan aikin firikwensin ko firikwensin ya lalace.

Ƙarin bayanin kula:

• Lokacin yin juriya na madauki da gwajin ci gaba tare da DVOM, koyaushe cire haɗin haɗin lantarki daga masu sarrafawa masu alaƙa - gazawar yin hakan na iya haifar da lalacewa ga mai sarrafawa.
• Yi amfani da taka tsantsan lokacin cire masu juyawa daga lamuran watsawa (don gwaji) kamar yadda ruwan watsa zafi zai iya zama cutarwa.

Tattaunawar DTC mai dangantaka

• A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.

Kuna buƙatar ƙarin taimako tare da lambar ku ta p2161?

Idan har yanzu kuna buƙatar taimako tare da DTC P2161, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.

NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
