Calaamadda gelinta sare ee gudbinta dareeraha heerkulka dareeraha gudbinta B

Maxay tani micnaheedu tahay?

Xeerkan Dhibaatada Baarista (DTC) waa koodh guud oo la isugu gudbiyo, taas oo macnaheedu yahay inay khuseyso baabuurta qalabaysan ee OBD-II oo leh dareeraha heerkulka gudbinta (Jeep, Ford, Nissan, Toyota, Honda, Infiniti, Acura, Jaguar, Lexus iyo tD) . In kasta oo dabeecadda guud tahay, tallaabooyinka dayactirka saxda ah way kala duwanaan karaan iyadoo ku xiran samaynta / tusaalaha.

Dareeraha dareeraha gudbinta (TFT) wuxuu bixiyaa calaamad ay adeegsadaan moduleka korantada korantada (PCM) si loo go'aamiyo dhibcaha beddelka, cadaadiska xariijinta, iyo xakameynta isku -beddelka beddelka (TCC). Dareemku wuxuu inta badan ku yaalaa digsiga saliidda gudbinta.

Dareenka TFT wuxuu ka helaa danab tixraac (sida caadiga ah 5 volts) PCM. Waxay beddeshaa iska caabbinta gudaha iyada oo ku xidhan heerkulka dareeraha gudbinta si loogu diro signalada danab ee dambe PCM. Dareemayaasha TFT waa nooc ka mid ah kuleyliye heerkulka taban (NTC). Tani waxay ka dhigan tahay in iska caabbinta gudaha ee dareeraha ay aad uga sareyso heerkulka saliidda. Awoodda signalada shidhka ee TFT ayaa hoos u dhacda marka heerkulka dareeraha gudbintu kor u kaco iyo sida kale.

P2743 waxaa la dejiyaa marka PCM -gu ogaado dareeraha gudbinta heerkulka dareeraha gudbinta sare "B". Tani waxay badanaa tilmaamaysaa wareeg furan. La tasho buug -gacmeedka adeegga soo -saarahaaga gaarka ah si aad u go'aamiso wareegga "B" ee baabuurkaaga.

Darnaanta xeerka iyo astaamaha

Darnaanta koodhkani waa dhexdhexaad ilaa daran. Xaaladaha qaarkood, koodkan ayaa laga yaabaa inuu muujiyo dhibaatada gudbinta. Waxaa lagu talinayaa in la hagaajiyo koodkan sida ugu dhakhsaha badan.

Astaamaha furaha mashiinka P2743 waxaa ku jiri kara:

• Laambadda digniinta matoorka ayaa shidan
• Hawlgal aan sax ahayn oo ah xajiyaha beddelka Xuddunta
• Wareegyada adag ama dib u dhaca
• Baabuurku wuxuu ku xayiran yahay hab-dhimis

sababaha

Sababaha DTC -kan waxaa ka mid noqon kara:

• Dareeraha dareeraha dareeraha gudbinta ee cilladaysan
• Dhibaatooyinka gudbinta
• Dhibaatooyinka fiilooyinka
• PCM haleysan

Hababka ogaanshaha iyo dayactirka

Ku billow adigoo si indho -indheyn ah u eegaya dareeraha heerkulka dareeraha gudbinta iyo xargaha la xiriira. Raadi xiriiro dabacsan, fiilooyin waxyeelloobay, iwm. Haddii waxyeello la helo, dayactir haddii loo baahdo, nadiifi xeerka oo fiiri inay soo noqoto. Kadib hubi waraaqaha adeegga farsamada (TSBs) dhibaatada. Haddii aan waxba la helin, waxaad u baahan doontaa inaad u sii gudubto baadhitaanka nidaamka tallaabo-tallaabo.

Kuwa soo socdaa waa hannaan guud maadaama tijaabinta xeerkani uu ka duwan yahay baabuurka iyo baabuurka. Si aad si sax ah u tijaabiso nidaamka, waxaad u baahan tahay inaad tixraacdo buug -gacmeedka ogaanshaha soo -saaraha.

Hore u tijaabi wareegga

Adeegso aalad iskaanka si aad ula socoto cabirka xogta dareeraha heerkulka gudbinta. Ka -saar shaashadda TFT; qiimaha aaladda baarista waa inuu hoos ugu dhacaa qiime aad u hooseeya. Ka dibna ku xidh jumper -ka guud ahaan boosteejada. Haddii aaladda sawirku ay hadda muujiso heerkul aad u sarreeya, iskuxirradu way fiican yihiin ECM -na waxay garan kartaa gelinta. Tani waxay ka dhigan tahay in dhibaatadu inta badan la xiriirto dareeraha oo aysan ahayn arrinta wareegga ama PCM.

Hubi dareeme

Ka -saar xiriiriyaha dareeraha dareeraha gudbinta. Kadib cabir iska caabbinta udhaxeysa labada boosteejo ee dareeraha oo leh DMM loo dhigay ohms. Bilow mishiinka oo hubi qiimaha miiska; qiimayaashu waa inay si tartiib tartiib ah hoos ugu dhacaan marka mishiinku kululaado (hubi cabbirka heerkulka mishiinka ee muraayada si aad u hubiso in mishiinku ku jiro heerkulka hawlgalka). Haddii heerkulka mishiinku kor u kaco laakiin iska -caabbinta TFT aysan hoos u dhicin, shidmahu waa cillad waana in la beddelaa.

Hubi wareegga

Hubi dhinaca danabka tixraaca ee wareegga: iyadoo dabku shidan yahay, isticmaal multimeter dhijitaal ah oo loo dejiyay volts si aad u hubiso danab tixraaca 5V oo ka socda PCM mid ka mid ah labada boosteejo ee dareeraha TCM. Haddii aysan jirin calaamad tixraac ah, ku xir mitir la dhigay Ohm (iyadoo dabku ka baxayo) inta u dhexeysa terminaalka tixraaca TFT iyo meesha tixraaca PCM -ga. Haddii akhrinta mitirku ka dhammaato dulqaad (OL), waxaa jira wareeg furan oo u dhexeeya PCM iyo dareeraha u baahan in la helo oo la dayactiro. Haddii miiska miiska akhriyo tiro tirooyin ah, waxaa jira sii socosho.

Haddii wax walba ay hagaagsan yihiin illaa heerkan, waxaad u baahan doontaa inaad hubiso haddii 5 volts uu ka soo baxayo PCM -ga marinka tixraaca korantada. Haddii aysan jirin danab tixraac 5V ah oo ka socda PCM, PCM -gu malaha waa cillad.

Hubi dhulka wareegga.

Ku xidh mitirka iska caabinta (shirkada OFF) inta u dhaxaysa terminalka dhulka ee dareeraha heerkulka gudbinta iyo terminalka dhulka PCM-ga. Haddii akhriska mitirku uu ka baxsan yahay dulqaadka (OL), waxaa jira wareeg furan oo u dhexeeya PCM-ga iyo dareemayaasha u baahan in la dhigo oo la hagaajiyo. Haddii miiska uu akhriyo qiime tiro, waxaa jira sii wadid. Ugu dambeyntii, hubi in PCM-gu uu si fiican u qotomo adiga oo ku xiraya hal mitir dhulka PCM-ga iyo kan kale dhulka chassis-ka. Mar labaad, haddii mitirku u akhriyo meel ka baxsan xadka (OL), waxaa jira wareeg furan oo u dhexeeya PCM iyo dhulka oo u baahan in la helo oo la dayactiro.

Haddii wax walba oo silsiladda ah la hubiyo, waxaa laga yaabaa inay dhibaato ka timaaddo gudbinta. Tani waxay si gaar ah run u tahay haddii xeerarka heerkulka dareeraha gudbinta lagu dhejiyo koodhadhka gudbinta kale.
