Lethathamo la lintlha tsa OBD-II DTC

Ho fokotsa / ho nchafatsa taolo ea potoloho / bula

See se bolela eng?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang mme e sebetsa ho likoloi tse ngata tsa OBD-II (1996 le tse ncha). Sena se ka kenyelletsa, empa ha se felle ho, Mercedes Benz, BMW, Dodge, Volkswagen, Ram, Sprinter, Audi, jj. Leha e le ka sebopeho sa kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa tlhahiso, sebopeho, sebopeho le phetolo. phetisetso.

Khoutu e bolokiloeng P2062 e bolela hore module ea taolo ea powertrain (PCM) ha e so fumane motlakase oa potoloho ea taolo bakeng sa pompo e fokotsang / nchafatso.

Lits'ebetso tsa Selective Catalyst Reduction (SCR) li kenya moralo o fokotsang kapa Diesel Exhaust Fluid (DEF) ka har'a likhase tse tsoang ka har'a sefahleho sa leraba, leraba la NOx le / kapa sesebelisoa se fetolang ka senotlolo se fokotsang (solenoid). Ente e baloang hantle ea DEF e phahamisa mocheso oa sesebelisoa mme e e lumella ho sebetsa ka nepo. E eketsa bophelo ba ts'ebeletso ea likarolo tsa sefa ebile e thusa ho fokotsa mesi e kotsi ea likhase tse kotsi tse tsoang moeeng. Sisteme eohle ea SCR e behiloe leihlo le ho laoloa ke PCM kapa molaoli ea ikemetseng (ea sebelisanang le PCM). Leha ho le joalo, molaoli o lekola li-sensor tsa mocheso oa khase oa O2, NOx le exhaust (hammoho le lisebelisoa tse ling) ho fumana nako e nepahetseng ea ente ea DEF (e fokotsang matla). Sebopeho sa Prefision DEF se hlokahala ho boloka mocheso oa khase o le maemong a amohelehang le ho ntlafatsa ho hloekisoa ha lintho tse silafatsang.

Pompo e fokotsang / nchafatso e sebelisetsoa ho hatella DEF tsamaisong ea metsi e fokotsang hore e sebelisoe ha ho hlokahala. PCM e lekola phepelo ea pompo ea phepelo bakeng sa liphetoho tse tsoelang pele le liperesente tsa mojaro. PCM e boetse e lekola sesebelisoa se le seng kapa tse fetang tse ngata tsa khatello tsamaisong ea phepelo e fokotsang ho bona hore na ho na le ho dutla tsamaisong.

Haeba PCM e lemoha khaello ea motlakase ho potoloho ea pompo ea reductant / regeneration, khoutu ea P2062 e tla bolokoa 'me lebone la ho se sebetse hantle (MIL) le ka hlaha. Leseli la MIL le ka hloka lipotoloho tse ngata tsa ho khantša - ha ho ka hloleha.

Boima ba DTC ee ke bofe?

Khoutu e bolokiloeng ea P2062 e lokela ho tšoaroa ka botebo mme e lokela ho sebetsoa kapele kamoo ho ka khonehang. Sistimi ea SCR e ka holofala ka lebaka la sena. Ts'enyo ea catalyst e ka hlaha haeba maemo a kentseng letsoho kholisong ea khoutu a sa lokisoe ka nako e loketseng.

A mang a matšoao a khoutu ke afe?

Matšoao a khoutu ea mathata a P2062 a ka kenyelletsa:

• Fokotsa matla a mafura
• Mosi o motšo o feteletseng o tsoang ho koloi
• Ts'ebetso ea enjene e fokotsehileng
• Likhoutu tse ling tse amanang le SCR

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena a ka kenyelletsa:

• Fokotsa phepelo moemeli pompo haelloang (overload)
• Potoloho e bulehileng kapa e khuts'oane ho potoloho ea taolo ea phepelo ea moemeli
• Taolo e mpe ea SCR / PCM kapa phoso ea mananeo

Ke mehato efe e meng ea ho rarolla bothata ba P2062?

Ho tseba khoutu ea P2062 ho tla hloka sekena sa tlhahlobo, digital volt / ohmmeter (DVOM), le mohloli oa tlhaiso-leseling e ikhethileng ea koloi.

U ka sebelisa mohloli oa tlhaiso-leseling ea koloi ea hau ho fumana Technical Service Bulletin (TSB) e ts'oanang le selemo sa koloi ea hau, ho etsa le ho etsa mohlala; hammoho le ho fallisoa ha enjene, likhoutu tse bolokiloeng le matšoao a fumanoe. Haeba u e fumana, e ka fana ka tlhaiso-leseling e nepahetseng ea tlhahlobo.

Sebelisa sekena (se hokahantsoeng le socket ea ts'oaetso ea koloi) ho fumana likhoutu tsohle tse bolokiloeng le data e amanang le foreimi. Ho kgothaletswa hore o ngole tlhahisoleseling lena pele o tlosa dikhoutu mme o leke ho khanna koloi ho fihlela PCM e kena maemong a loketseng kapa khoutu e hlakotsoe.

Haeba PCM e kena ka mokhoa o loketseng ka nako ena, khoutu e bohareng mme e ka ba thata haholo ho e fumana. Maemong ana, maemo a tlatselitseng ho bolokeng khoutu a ka hloka ho mpefala pele ho ka fumanoa tlhahlobo e nepahetseng.

Haeba khoutu e hlophisoa bocha hanghang, mohato o latelang oa ho hlahloba o tla hloka hore o batlisise mohloli oa tlhaiso-leseling ea koloi bakeng sa lits'oants'o tsa "block block", li-pinout, li-faceplates tsa sehokedi le lits'ebetso tsa liteko tsa likarolo.

hata 1

Sebelisa DVOM ho leka pompo e fokotsang phepelo ea litanka ho latela litlhaloso tsa moetsi. Likarolo tse sa feteng tlhahlobo kahare ho litekanyetso tse lumellehang li lokela ho nkuoa li fosahetse.

hata 2

Sebelisa mohloli oa tlhahlobo ea koloi le DVOM ho lekola pompo e fokotsang phepelo ea pompo (hangata matla a betri) ha pompo e sebelisoa. Haeba maemo a hajoale a sa lumelle ts'ebetso e ikemetseng, sebelisa sekena ho kenya pompo ea hau ka letsoho.

hata 3

Haeba pompo e fokotsang e sebetsa, sebelisa DVOM ho lekola li-circuits tsa ho kenya le ho tsoa ho phanele ea fuse, PCM le switch switch. Tlosa balaoli bohle pele u sebelisa DVOM bakeng sa liteko.

• Likhoutu tse fokotsang tsa taolo ea pompo tse fokotsang hangata li amahanngoa le khaello ea wiring (ka lebaka la motlakase)

Haeba u ntse u hloka thuso ka DTC P2062, beha potso litlatsong tse ka tlase ho sengoloa sena.

HLOKOMELA. Tlhahisoleseling ena e fanoa molemong oa tlhaiso-leseling feela. Ha ea rereloa hore e sebelisoe joalo ka khothaletso ea tokiso mme ha re na boikarabello bakeng sa ketso efe kapa efe eo u e nkang koloing efe kapa efe. Lintlha tsohle tse fumanehang sebakeng sena sa marang-rang li sirelelitsoe ka litokelo tsa bangoli.
