Ena ke Khoutu ea Mathata ea Generic Powertrain Diagnostic Trouble (DTC) e sebetsang ho likoloi tse ngata tsa OBD-II (1996 le tse ncha). Sena se ka kenyelletsa, empa ha se felle feela ho, Ford, Dodge, Ram, Jeep, Chevrolet, Volkswagen, Mercedes, jj. Leha e le sebopeho sa kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa mohlala, sebopeho, phetisetso le phetiso. ...

Khoutu ea mathata ea OBD-II P245A le likhoutu tse amanang le eona P245B, P245C, le P245D li amahanngoa le potoloho ea taolo e pholileng ea EGR.

Morero oa potoloho ea taolo e pholileng ea EGR ke ho bula le ho koala belofo ea ho feta ea EGR tlasa maemo a reriloeng pele ho thibela khatello e fetelletseng ea EGR, e tsejoang e le plugging, e amang tšebetso le ts'ebetso ea enjene ea dizeli. Mojule oa taolo ea enjene (ECM) o lekola potoloho ena ka ho amohela mehato ea litšupiso ho tsoa ho switjha ea mocheso oa EGR le likarolo tse ling tse amanang le eona ho laola sephahla se pholileng sa EGR, se khutlisetsang likhase tsa ho qeta matla mollong o mongata. Sebaka sa valve ea EGR, pholileng ea EGR, sesebelisoa sa mocheso le likarolo tse amanang le sona se fapana ho ea ka koloi ho ea koloing 'me se fapana haholo ho tloha ho moetsi ho ea ho moetsi.

Ha ECM e lemoha matla a sa tloaelehang kapa khanyetso ho potoloho ea taolo e pholileng ea EGR, khoutu ea P245A e tla beha mme leseli la enjene ea cheke, lebone la ts'ebeletso ea enjene, kapa ka bobeli li ka bonesa.

Boima ba DTC ee ke bofe?

Boima ba khoutu ena bo ka fapana haholo ho tloha ho e itekanetseng ho ea ho e matla, ho latela matšoao a itseng a bothata le boemo ba chiller le ts'ebetso ea valve e fetang. Sephahla sa EGR se nang le sekoli kapa potoloho ea taolo e ka baka mollo o feteletseng le enjene ea pele, e ka senyang li-piston, li-valve le lisebelisoa tse ling tse amanang le enjene ea kahare.

A mang a matšoao a khoutu ke afe?

Matšoao a khoutu ea bothata ea P245A a ka kenyelletsa:

• Teko ea Mocheso ea Enjin e ka Hloloa
• Thothetsang molelo lla kapa kokota nakong matsapa
• Keketseho ea tšebeliso ea mafura
• Ts'ebetso e mpe ea enjene
• Leseli la enjene ea ts'ebeletso le tla bonesoa haufinyane
• Leseli la enjene ea ho hlahloba le laetse

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena ea P245A a ka kenyelletsa:

• Ho felisa mocheso oa khase o pholileng o pholileng o se nang sekoli
• Ho khutsuoa kapa ho senyeha ha moea o pholileng oa khase
• Mocheso o sebetsa hampe
• Ho aha khabone e ngata
• Wiring e fosahetseng kapa e senyehileng
• Sehokelo se senyehileng, se senyehileng kapa se hlephileng
• ECM e nang le phoso

Ke mehato efe e meng ea ho rarolla bothata ba P245A?

Mohato oa pele oa ho rarolla bothata bofe kapa bofe ke ho lekola li-Bulletins (TSBs) tse ikhethileng tsa koloi ka selemo, mohlala le phepelo ea motlakase. Maemong a mang, sena se ka u bolokela nako e telele ka ho u supisa tsela e nepahetseng.

Mohato oa bobeli ke ho fumana likarolo tsohle tse amanang le potoloho e pholileng ea EGR le ho li hlahloba bakeng sa tšenyo e hlakileng ea 'mele. Ho itšetlehile ka koloi e khethehileng, potoloho ena e ka kenyelletsa likarolo tse 'maloa, ho akarelletsa le mocheso oa mocheso, valve ea bypass, valve ea EGR, EGR cooler, le mochine oa ho laola enjene. Etsa tlhahlobo e phethahetseng ea pono ho hlahloba mehala e amanang le eona bakeng sa mefokolo e totobetseng joalo ka mengoapo, makhopho, mehala e pepeneneng, kapa matšoao a cheleng. Ka mor'a moo, hlahloba lihokelo le likhokahano bakeng sa ts'ireletso, kutu le tšenyo ho likhokahano. Ts'ebetso ena e tlameha ho kenyelletsa likhokahano tsohle tsa wiring ho likarolo tsohle, ho kenyeletsoa switch ea mocheso oa EGR le yuniti ea taolo ea enjene. Sheba leqephe le khethehileng la lintlha tsa koloi ho hlahloba tlhophiso ea EGR bypass valve control circuit le ho netefatsa karolo e 'ngoe le e' ngoe e kenyelletsoeng potolohong, e ka kenyelletsang fuse kapa sehokelo sa fusible lits'ebetsong tse ling.

Mehato e tsoetseng pele

Mehato ea tlatsetso e ba koloi e ikhethang 'me e hloka hore lisebelisoa tse tsoetseng pele tse loketseng li etsoe ka nepo. Ts'ebetso tsena li hloka litokomane tsa dijithale tsa multimeter le tse ikhethileng tsa koloi.

Teko ea Voltage

Mefuta ea litšupiso le mefuta e lumelletsoeng e ka fapana ho latela koloi e itseng le phetolo ea potoloho. Lintlha tse ikhethileng tsa tekheniki li tla kenyelletsa litafole tsa ho rarolla mathata le tatellano e nepahetseng ea mehato ho u thusa ho fumana tlhahlobo e nepahetseng.

Haeba ts'ebetso ena e fumana hore mohloli oa motlakase kapa mobu ha o eo, ho ka hlokahala hore ho etsoe teko ea ho tsoela pele ho netefatsa bots'epehi ba mehala, likhokelo le likarolo tse ling. Liteko tsa tsoelo-pele li lokela ho lula li etsoa ka motlakase o khaohantsoeng le potoloho, 'me ho bala ho tloaelehileng bakeng sa wiring le likhokelo ho lokela ho ba 0 ohms ea ho hanyetsa. Ho hanyetsa kapa ho se tsoele pele ho bonts'a phoso ea wiring e bulehileng, e khutsufalitsoeng kapa e senyehileng mme e hloka ho lokisoa kapa ho nkeloa sebaka.

Ke mekhoa efe e metle ea ho lokisa khoutu ee?

• Ho nchafatsa moea o pholileng oa ho qeta monono
• Ho nchafatsa valve e fetang e pholileng ea EGR
• Ho fetola mocheso oa mocheso
• Ho hloekisa likhokelo ho tsoa ts'enyehong
• Lokisa kapa u tlose mohala o fosahetseng
• Ho hloekisa li-depositi tsa khabone
• Ho khanya kapa ho nkela ECM sebaka

Phoso e akaretsang

• Ho khutlisetsa valve e fetang e pholileng ea EGR ha moaho oa khabone kapa mohala o fosahetseng o baka ECM ho beha khoutu ena.

Rea ts'epa hore tlhaiso-leseling e seng e thusitse ho u supisa tsela e nepahetseng ea ho rarolla bothata ba EGR bo pholileng ba taolo ea potoloho ea DTC. Sengoloa sena se etselitsoe tlhaiso-leseling feela mme lintlha tse ikhethang tsa tlhaiso-leseling le lintlha tsa ts'ebeletso bakeng sa koloi ea hau li lokela ho lula li etelletsa pele.
