Idatha ye-OBD-II DTC
Isignali yokufaka ephansi kusifunda sokuzwa inzwa yokushisa okushisa uketshezi B
Kusho ukuthini lokhu?
Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlome nge-OBD-II ezinenzwa yokushisa okokuhambisa uketshezi (iJeep, Ford, Nissan, Toyota, Honda, Infiniti, Acura, Jaguar, Lexus ne-tD) . Ngaphandle kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngokwenziwa / imodeli.
Inzwa yokudlulisa amanzi okushisa (TFT) inikeza isignali esetshenziswa yi-powertrain control module (PCM) ukuthola amaphuzu okushintsha, ingcindezi yomugqa, kanye nolawulo lwe-torque converter clutch (TCC). Inzwa ivame ukutholakala epanini lamafutha lokuhambisa.
Inzwa ye-TFT ithola i-voltage voltage (imvamisa ama-volts ama-5) evela ku-PCM. Ishintsha ukumelana kwayo kwangaphakathi ngokuya ngethempelesha loketshezi lokuhambisa ukuze ithumele isignali yamandla obuyela emuva ku-PCM. Izinzwa ze-TFT ziwuhlobo lwe-thermistor (NTC) engasebenzi kahle yokushisa. Lokhu kusho ukuthi ukumelana kwangaphakathi kwenzwa kuphambene ngokungafani nethempelesha kawoyela. Amandla esignali enzwa ye-TFT ancipha lapho izinga lokushisa lokuhambisa uketshezi liphakama futhi okuphambene nalokho.
I-P2742 isethwe lapho i-PCM ithola isiginali ephansi yokudlulisela uketshezi lokushisa "B". Lokhu kuvamise ukukhombisa isifunda esifushane esifundeni. Xhumana namanuwali wakho wensiza womkhiqizi ukuthola ukuthi isifunda sini "B" esenzelwe imoto yakho.
Isibonelo senzwa yokushisa okokuhambisa uketshezi: 
Amakhodi wesekethe we-Transmission Fluid Temperature ahambisanayo:
- I-P2740 Transmission Fluid Temperature Sensor B Ukungasebenzi Kwesekethe
- I-P2741 Transmission Fluid Temperature Sensor B Circuit Range / Performance
- I-P2743 High Input Transmission Fluid Temperature Sensor B Circuit
- P2744 Transmission Fluid Temperature Sensor B Ukungasebenzi
Ukuqina kwekhodi nezimpawu
Ubunzima bale khodi bumaphakathi ukuya kobunzima. Kwezinye izimo, le khodi ingase ibonise inkinga yokudlulisela. Kunconywa ukuthi ulungise le khodi ngokushesha okukhulu.
Izimpawu zekhodi yenjini engu-P2742 zingafaka:
- Isibani sokuxwayisa injini siyavela
- Ukusebenza okungalungile kwe-torque converter clutch
- Ukushintsha okunamandla noma okubambezelekile
- Imoto ibhajwe kumodi yokufa
izizathu
Izimbangela zale DTC zingafaka:
- Inzwa yokushisa uketshezi olunamaphutha
- Izinkinga zokuhambisa
- Izinkinga zokufaka izintambo
- I-PCM enamaphutha
Izinqubo zokuxilonga nokulungisa
Qala ngokubuka ngokuhlola inzwa yokushisa okokuhambisa uketshezi kanye nentambo ehambisanayo. Bheka ukuxhumana okuxekethile, izintambo ezilimele, njll. Uma kutholakala umonakalo, lungisa lapho kudingeka khona, sula ikhodi bese ubona ukuthi iyabuya yini. Bese ubheka ama-bulletins wensizakalo yezobuchwepheshe (ama-TSB) ukuthola inkinga. Uma kungatholakali lutho, kuzodingeka uqhubekele ekuhlolweni kwesistimu ngezinyathelo.
Okulandelayo inqubo ejwayelekile njengoba ukuhlolwa kwale khodi kwehlukile emotweni kuya emotweni. Ukuze uvivinye ngokunembile isistimu, udinga ukubhekisa kutchartchch flowchart yomkhiqizi.
Hlola kuqala isifunda
Sebenzisa ithuluzi lokuskena ukuqapha ipharamitha yedatha yesensa yokushisa. Nqamula inzwa ye-TFT; inani lamathuluzi wokuskena kufanele lehle liye kunani eliphansi kakhulu. Bese uxhuma i-jumper ngaphesheya kwamatheminali. Uma ithuluzi lokuskena manje likhombisa ukushisa okuphezulu kakhulu, ukuxhumana kuhle futhi i-ECM iyakwazi ukubona okokufaka. Lokhu kusho ukuthi inkinga ihlobene kakhulu nenzwa hhayi inkinga yesekethe noma ye-PCM.
Hlola inzwa
Nqamula isixhumi sesixhumi sesisindo sokushisa. Bese ulinganisa ukumelana phakathi kwamatheminali amabili enzwa nge-DMM esethwe kuma-ohms. Qala injini bese uhlola inani le-counter; amanani kufanele anciphe kancane kancane njengoba injini ifudumala (hlola igeji yokushisa kwenjini kudeshibhodi ukuze uqiniseke ukuthi injini isebenza ngokushisa okusebenzayo). Uma izinga lokushisa kwenjini likhuphuka kepha ukumelana ne-TFT kunganciphi, inzwa inephutha futhi kufanele ithathelwe indawo.
Hlola isifunda
Bheka uhlangothi lwamandla wesethenjwa wesifunda: lapho kufakwa khona ukukhanya, sebenzisa i-multimeter yedijithali esethwe kuma-volts ukuhlola i-5V voltage voltage evela ku-PCM kwenye yamatheminali amabili enzwa ye-TCM. Uma kungekho siginali eyisithenjwa, xhuma imitha esethwe ku-Ohm (ukucisha ukucisha) phakathi kwesiginali sereferensi se-TFT kanye ne-PCM reference terminal. Uma ukufundwa kwemitha kuphelelwe ukubekezelelana (i-OL), kunesekethe evulekile phakathi kwe-PCM nenzwa edinga ukutholakala nokulungiswa. Uma i-counter ifunda inani lezinombolo, kunokuqhubeka.
Uma konke kuhamba kahle kuze kube manje, uzofuna ukubheka ukuthi ama-volts ama-5 aphuma kwi-PCM endaweni yokugcina amandla e-voltage. Uma kungekho voltage oyireferensi ongu-5V ovela kwi-PCM, kungenzeka ukuthi i-PCM inephutha.
Hlola umhlabathi wesifunda.
Xhuma imitha yokumelana (i-ignition OFF) phakathi kwetheminali yaphansi kwinzwa yokushisa yoketshezi lokudlulisa kanye netheminali yaphansi ku-PCM. Uma ukufundwa kwemitha kuphelelwe ukubekezelelana (OL), kukhona isifunda esivulekile phakathi kwe-PCM kanye nenzwa okudingeka itholakale futhi ilungiswe. Uma isibali sifunda inani lezinombolo, kukhona ukuqhubeka. Okokugcina, qiniseka ukuthi i-PCM isekelwe kahle ngokuxhuma imitha eyodwa kutheminali ephansi ye-PCM kanye nenye endaweni ye-chassis. Nakulokhu futhi, uma imitha ifundeka ngaphandle kobubanzi (OL), kukhona isekethe evulekile phakathi kwe-PCM nomhlabathi odinga ukutholwa futhi ulungiswe.
Uma yonke into eseketangeni ihlolwe, kungahle kube nenkinga ngokudluliswa. Lokhu kuyiqiniso ikakhulukazi uma amakhodi okushisa okushisa oketshezi asethwe ngokuhlangana namanye amakhodi wokudlulisa.
