I-P2062 Reductant / Regeneration Control Circuit / Evulekile

Idatha ye-OBD-II DTC

Ukunciphisa / ukuvuselelwa kokulawulwa kwesifunda / okuvulekile

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungabandakanya kepha akukhawulelwe kwaMercedes Benz, BMW, Dodge, Volkswagen, Ram, Sprinter, Audi, njll. Naphezu kwemvelo ejwayelekile, izinyathelo zokulungisa ngqo zingahluka ngokuya ngonyaka wokwenziwa, ukwenziwa, imodeli nokulungiswa. .

Ikhodi egcinwe i-P2062 isho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ayitholakalanga i-voltage kusekethe yokulawula yempompo yokunciphisa / yokuvuselela.

Izinhlelo ze-Selective Catalyst Reduction (SCR) zifaka ukwakheka okunganciphisi noma i-Diesel Exhaust Fluid (DEF) kumagesi wokukhipha akhuphuka esihlungi se-particulate, isicupho se-NOx kanye / noma isiguquli se-catalytic nge-reductant injection valve (solenoid). Umjovo obalwe ngokunembile we-DEF uphakamisa izinga lokushisa kwento yokuhlunga futhi uyivumele ukuthi isebenze kahle. Inweba impilo yensiza yezinto zokuhlunga futhi isiza ekwehliseni ukukhishwa kwamagesi ayingozi wokukhipha emkhathini. Lonke uhlelo lwe-SCR lubhekiwe futhi lulawulwa yi-PCM noma isilawuli esizimele sodwa (esisebenzisana ne-PCM). Kunoma ikuphi, isilawuli sihlola izinzwa ze-O2, NOx nezokushisa kwegesi (kanye nokunye okufakwayo) ukuthola isikhathi esifanele somjovo we-DEF (owehlisayo). Umjovo we-Precision DEF uyadingeka ukugcina ukushisa kwegesi okukhipha ngaphakathi kwemingcele eyamukelekayo nokwenza ngcono ukuhlunga kokungcola.

Iphampu yokunciphisa / yokuvuselela isetshenziselwa ukucindezela i-DEF ohlelweni lokunciphisa uketshezi lokusetshenziswa lapho kudingeka. I-PCM ihlola amandla empompo okuhlinzeka ngokushintshashintsha okuqhubekayo namaphesenti wokulayisha. I-PCM ibuye ibheke inzwa eyodwa noma ngaphezulu yengcindezi ohlelweni lokuhlinzeka ngokunciphisa ukuthola ukuthi kukhona yini ukuvuza kuhlelo.

Uma i-PCM ithola ukuntuleka kwe-voltage kumjikelezo wokulawula iphampu ye-reductant/regeneration, ikhodi P2062 izogcinwa futhi isibani senkomba esingasebenzi kahle (MIL) singase sivele. Ukukhanyisa kwe-MIL kungase kudinge imijikelezo eminingi yokuthungela - uma kwenzeka kwehluleka.

Buyini ubunzima bale DTC?

Ikhodi egcinwe ku-P2062 kufanele iphathwe ngokungathi sína futhi kufanele isingathwe ngokushesha okukhulu. Uhlelo lwe-SCR lungakhubazeka ngenxa yalokhu. Ukulimala kweCatalyst kungenzeka uma izimo ezibe nomthelela ekuphikeleni kwekhodi zingalungiswa ngesikhathi esifanele.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2062 zingafaka:

• Ukwehla kwamandla kaphethiloli
• Intuthu emnyama eyeqile ephuma ekuqothulweni kwezimoto
• Ukunciphisa ukusebenza kwenjini
• Amanye amakhodi ahlobene ne-SCR

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Ukunciphisa i-ejenti yokuhlinzeka ngempompo engalungile (ukulayisha ngokweqile)
• Isifunda esivulekile noma esifushane esifundeni sokulawula ukunikezwa kwe-ejenti
• Isilawuli se-SCR / PCM esingalungile noma iphutha lohlelo

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2062?

Ukuhlonza ikhodi ye-P2062 kudinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wokuxilonga oqondene nemoto.

Ungasebenzisa umthombo wolwazi lwemoto yakho ukuthola i-Technical Service Bulletin (TSB) efana nonyaka wemoto yakho, ukwakheka kwayo kanye nemodeli yakho; kanye nokususwa kwenjini, amakhodi agciniwe nezimpawu ezitholakele. Uma uyithola, ingahlinzeka ngemininingwane ewusizo yokuxilonga.

Sebenzisa isithwebuli (esixhunywe kusokhethi yokuxilonga yemoto) ukuthola wonke amakhodi agciniwe kanye nedatha yozimele efriziwe. Kunconywa ukuthi ubhale phansi lolu lwazi ngaphambi kokususa amakhodi bese uhlola ukushayela imoto kuze kube yilapho i-PCM ingena kumodi elungele noma ikhodi isuliwe.

Uma i-PCM ingena kumodi elungile ngalesi sikhathi, ikhodi iphakathi futhi ingaba nzima kakhulu ukuxilonga. Kulokhu, izimo ezibe nomthelela ekugcineni ikhodi zingadinga ukuba zimbi kakhulu ngaphambi kokuba kutholakale ukuxilongwa okunembile.

Uma ikhodi isethwa kabusha ngokushesha, isinyathelo esilandelayo sokuxilonga sizodinga ukuthi useshe umthombo wolwazi lwemoto yakho ukuthola imidwebo yama-block diagnostic, ama-pinout, ama-faceplates okuxhuma, nezinqubo / imininingwane yokuhlolwa kwengxenye.

Isinyathelo 1

Sebenzisa i-DVOM ukuhlola ipompo lokuhambisa ithangi elinciphisayo ngokuya ngemininingwane yomkhiqizi. Izinto ezingaphumeleli ukuhlolwa ngaphakathi kwemingcele ephezulu evunyelwe kufanele zithathwe njengezinephutha.

Isinyathelo 2

Sebenzisa umthombo wakho wokuxilonga imoto ne-DVOM ukuhlola amandla wempompo yokuhambisa anciphise (imvamisa yamandla webhethri) nepompo yenziwe yasebenza. Uma izimo zamanje zingakuvumeli ukusebenza okuzenzakalelayo, sebenzisa isithwebuli ukwenza kusebenze ipompo lakho ngesandla.

Isinyathelo 3

Uma ipompo elincishayo lisebenza, sebenzisa i-DVOM ukuhlola amasekethe wokufaka nawokukhipha kusuka kuphaneli le-fuse, i-PCM, ne-switch ye-ignition. Nqamula bonke abalawuli ngaphambi kokusebenzisa i-DVOM ukuhlola.

• Amakhodi we-overvoltage wokulawula amaphampu anciphisayo avame ukuhlotshaniswa nokushoda kwezintambo (ngenxa yamandla kagesi)
