1️⃣ Ingcindezi yokuthatha eyonakele kanye nenzwa yezinga lokushisa
Ukuhlaziya imbangela: Isignali yengcindezi yokuthatha ayijwayelekile, futhi i-ECU ayikwazi ukuthola ulwazi olulungile lokuthatha, okuholela ekujovweni kukaphethiloli okungavamile.Ukuvutha akwanele, injini ivilapha, futhi kuphuma intuthu emnyama ngesikhathi sokufakwa kukaphethiloli.Izinkinga ngoxhumo lwezintambo zezintambo kanye nokwehluleka kwezinzwa kungabangela lokhu kwehluleka.
Isixazululo: Hlola umfutho womoya owuthathayo kanye nenzwa yezinga lokushisa.
2️⃣ Ukulimala kwenzwa yokushisa kwamanzi
Ukuhlaziya imbangela: lapho inzwa yokushisa kwamanzi ihluleka futhi i-ECU ithola ukuthi isignali yokuphuma yenzwa yokushisa kwamanzi ayithembekile, inani elingena esikhundleni lisetshenziswa.I-ECU ikhawulela i-torque yenjini ngenhloso yokuvikela injini.
Isixazululo: hlola inzwa yokushisa kwamanzi.
3️⃣ Ukulimala kwenzwa yomfutho kawoyela
Ukuhlaziya imbangela: i-probe yenzwa yokucindezela uwoyela yonakaliswe kakhulu, i-ECU ithola ukuthi inzwa yokucindezela uwoyela ayixhunyiwe, futhi inani elibonisiwe lensimbi yinani elingena esikhundleni sangaphakathi le-ECU.
Isixazululo: hlola inzwa yokucindezela kwamafutha.
4️⃣ Ukuxhumana okungalungile kwetheminali yesokhethi ye-OBD
Ukuhlaziya imbangela: Itheminali yesokhethi ye-OBD iyaphuma, okuholela ekuthinteni okubi, futhi ithuluzi lokuxilonga ne-ECU azikwazi ukuxhumana.
Isixazululo: hlola itheminali yesokhethi ye-OBD.
5️⃣ I-nitrogen sensor wire harness short circuit
Ukuhlaziya imbangela: ihhanisi lenzwa ye-nitrogen ne-oksijini seligugile, liyajikeleza futhi limiswe phansi, futhi inzwa ye-nitrogen ne-oxygen ayikwazi ukusebenza ngendlela evamile, okuholela ekukhishweni ngokweqile, umkhawulo we-torque yenjini kanye ne-alamu yesistimu.
Isixazululo: hlola izintambo zocingo zenzwa ye-nitrogen ne-oxygen.
6️⃣ Umonakalo webhokisi elidluliselwe ekushiseni ngemuva kokwelashwa
Ukuhlaziya imbangela: Bopha iphutha lesekhethi evulekile.
Isixazululo: hlola futhi ulungise i-harness yebhokisi lokudlulisa ukushisa.
7️⃣ Isofthiwe engezansi yethuluzi ayilungile futhi ayithumeli isignali yesivinini semoto
Ukuhlaziya imbangela: phakathi nokushayela, isignali yesivinini semoto ethunyelwe ithuluzi ngokuzumayo yehla ibe ngu-0. Ukushintsha kwesignali yesivinini semoto kuholela ekushintsheni komthamo kawoyela olawulayo we-ECU, okuholela ekunqanyulweni kukaphethiloli ngokushesha.
Isixazululo: buyekeza ithuluzi libe yinguqulo yakamuva
8️⃣ Ukuvinjwa kwepayipi lokubuyisela urea lohlelo lwe-SCR
Ukuhlaziya imbangela: ama-sundries epayipi elibuyisela i-urea avinjiwe, okuholela ekuhlulekeni kwesistimu ukujova i-urea ngokujwayelekile, ukukhishwa kudlula okujwayelekile, umkhawulo we-torque yenjini, kanye ne-alamu yesistimu.
Isixazululo: hlola ipayipi lokubuyisela urea.
9️⃣ Isimo sesokhethi yokugcina yesixhumi sepayipi lokushisisa le-urea reflux
Ukuhlaziya imbangela: ukwehluleka kwesixhumi sepayipi yokubuyisela urea yokufudumeza.
Isixazululo: lungisa itheminali bese uxhuma kabusha i-plug-in.
