P0703 Torque / Brake switch B Circuit Kuwonongeka

Khodi Yovuta ya OBD-II - P0703 - Kufotokozera Zaukadaulo

P0703 - Torque Converter/Brake Switch B Kusokonekera kwa Circuit

Kodi vuto la P0703 limatanthauza chiyani?

Izi Diagnostic Trouble Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse kuyambira 1996 (Ford, Honda, Mazda, Mercedes, VW, etc.). Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

Mukawona kuti nambala ya P0703 yasungidwa m'galimoto yanu ya OBD-II, zikutanthauza kuti gawo loyendetsa mphamvu ya powertrain (PCM) lapeza kusagwira bwino kwakanthawi kosinthira mabuleki kosinthira makokedwe. Nambala iyi imangogwira ntchito pamagalimoto okhala ndi zotengera zodziwikiratu.

Kutumiza kwazokha (mumagalimoto opanga zambiri) akhala akuyendetsedwa pakompyuta kuyambira zaka za m'ma 1980. Magalimoto ambiri okhala ndi OBD-II amayang'aniridwa ndi wowongolera omwe amaphatikizidwa ndi PCM. Magalimoto ena amagwiritsa ntchito gawo loyimirira lokhalo la powertrain lomwe limalumikizana ndi PCM ndi owongolera ena kudzera pa Controller Area Network (CAN).

Chosinthira makokedwe ndi mtundu wa ma hydraulic clutch omwe amalumikiza injini ndikutumiza. Galimoto ikamayenda, chosinthira ma torque chimalola kuti torque itumizidwe ku shaft yolowera. Galimoto ikayima (injini ikakhala idless), chosinthira makokedwe chimatenga makokedwe a injini pogwiritsa ntchito makina ovuta a clutch. Izi zimalola injini kuti igwire ntchito popanda kuyimitsa.

Chosinthira makokedwe ogwiritsira ntchito mu OBD-II yamagalimoto okhala ndi zida amalola injini kuti izitseka pamalowedwe olowera pamavuto ena. Izi zimachitika nthawi zambiri kufala kwakasunthira kumtunda, galimotolo lafika pa liwiro linalake ndipo liwiro la injini lakwaniritsidwa. Pogwiritsa ntchito njira yotsekera, torque converter clutch (TCC) imachepetsedwa pang'onopang'ono mpaka kutumizira kumagwira ntchito ngati kuti kumangirizidwa ku injini ndi 1: 1. Dongosololi limathandizira pakuwononga mafuta komanso magwiridwe antchito a injini. Kutseka kwa chosinthira makokedwe kumakwaniritsidwa ndi zida zamagetsi zamagetsi zomwe zimayang'anira tsinde lodzaza masika kapena valavu ya mpira. PCM ikazindikira kuti zinthuzo ndi zolondola, chotseka chokhacho chimatsegulidwa ndipo valavu imalola madzimadzi kupyola chosinthira (pang'onopang'ono) ndikuyenda molunjika ku thupi la valavu.

Makina osinthira makokedwe amayenera kutayidwa injini isanathamange mpaka pamlingo winawake, ndipo nthawi zonse galimoto isanachite ulesi. Kupanda kutero, injiniyo ibwerera. Chimodzi mwazizindikiro zomwe PCM imayang'ana mukamayimitsa kogwiritsira ntchito torque ndikusindikiza chidutswa chazitsulo. Pakhosi lonyamula likapsinjika, cholembera chomenyera chimapangitsa olumikizanawo kuti atseke, kutseka dera limodzi kapena angapo. Maseketiwa akatsekedwa, magetsi oyimitsa amabwera. Chizindikiro chachiwiri chimatumizidwa ku PCM. Chizindikiro ichi chimawuza PCM kuti choyimitsa chophwanyaphwanya ndichipsinjo ndipo chosinthira chokhacho chimayenera kutayidwa.

Khodi ya P0703 imanena za amodzi mwamabwalo osinthira mabuleki. Onaninso buku lothandizira galimoto yanu kapena deta yonse kuti mudziwe zambiri zokhudza dera lomwe likugwirizana ndi galimoto yanu.

Zizindikiro ndi kuuma kwake

Nambala iyi ikuyenera kuonedwa mwachangu chifukwa kuwonongeka kwakanthawi kwamkati kumatha kuchitika ngati loko kwa TCC kwakhala sikugwira ntchito kwakanthawi. Mitundu yambiri idapangidwa mwanjira yoti PCM isokoneze loko kwa TCC ndikuyika njira zowongolera kufalikira ngati mtundu uwu wa code usungidwa.

Zizindikiro za chikhombo cha P0703 zitha kuphatikizira izi:

• Maofesi a injini galimoto ikamayima kuti iime
• Loko la TCC litha kulephereka
• Kuchepetsa mafuta
• Mphamvu yama injini yochepetsedwa (makamaka pamisewu ikuluikulu)
• Zida zosakhazikika zosunthira
• Mabuleki osagwira ntchito
• Nyali zoyimitsa zomwe sizizimitsa komanso zimayaka nthawi zonse
• Palibe kutseka kwa torque converter
• Kuyimitsa panthawi yoyimitsa komanso m'magiya chifukwa chotseka chosinthira ma torque osatulutsa.
• Kusungidwa kwa DTC
• Kuwala kwa MIL
• Ma code ena okhudzana ndi chosinthira ma torque, torque converter clutch, kapena torque converter lockup.

Zifukwa za P0703 kodi

Khodi iyi nthawi zambiri imayamba chifukwa chakusintha kolakwika kwa ma brake light switch kapena fuse yowombedwa mugawo la mabuleki. Ma soketi a nyale za mabuleki asokonekera, mababu ozima kapena ofupikitsidwa, mawaya/zolumikizira zoonekera kapena zachita dzimbiri zingayambitsenso DTC.

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Opunduka ananyema lophimba
• Kusintha kosasintha kwa mabuleki
• Dera lalifupi kapena dera lotseguka mu zingwe ndi / kapena zolumikizira mdera losinthira mabuleki lolembedwa ndi chilembo B
• Fuse lama fuyusi kapena fuse
• Zolakwika za PCM kapena PCM zolakwika

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Pezani sikani, digito volt / ohmmeter, ndi buku lothandizira (kapena deta yonse) pagalimoto yanu. Mudzafunika zida izi kuti mupeze nambala ya P0703.

Yambani ndikuwona zowunikira zazingwe zama brake ndikuyang'ananso kwa zingwe pansi pake. Onetsetsani mafyuzi oyatsa magetsi ndikusintha ma fuseti ngati kuli kofunikira.

Lumikizani chojambulira ku chojambulira cha matenda ndikupeza ma code onse osungidwa ndikuwumitsa chimango. Lembani izi chifukwa zitha kukuthandizani kuti muwunikenso. Chotsani ma code ndikuyesa kuyendetsa galimoto kuti muwone ngati ikukhazikitsanso nthawi yomweyo.

Ngati ndi choncho: yang'anani magetsi a batri pa brake switch switch input dera pogwiritsa ntchito DVOM. Magalimoto ena amakhala ndi mabuleki opitilira umodzi chifukwa choponderetsa chodetsa nkhawa, magetsi oyimitsa amayenera kuyatsidwa ndipo chosinthira cha torque chikuyenera kuyimitsidwa. Onaninso buku lothandizira galimoto yanu kuti mudziwe momwe brake switch yanu ikukonzekera. Ngati pali ma batire pamagetsi olowera, khumudwitsani chowumitsa ndikuwunika batire yamagetsi pagawo lotulutsa. Ngati mulibe magetsi pagawo lotulutsa, ganizirani kuti batani la brake ndi lolakwika kapena silinasinthidwe molakwika.

Zowonjezera zowonjezera:

• Chongani fyuluta ya fayiloyi ndi chinsalu chanyema. Mafyuzi omwe amawoneka kuti ndi abwino pachiyeso choyambirira atha kulephera dera likakhala likulemera.
• Nthawi zambiri, kusinthana kolakwitsa kosasinthidwa molondola kumatha kuonedwa ngati kolakwika.
• Kuti muyesere mwachangu ntchito ya TCC, bweretsani galimotoyo pa liwiro la mseu (pa kutentha kwachizolowezi), dinani pang'ono pakhomapo ndikuligwetsa kwinaku mukufulumira. Ngati RPM ikuwonjezeka pamene mabuleki agwiritsidwa ntchito, TCC imagwira ntchito ndipo chosinthira chimatulutsa bwino.
• Ngati dongosolo la TCC likugwirabe ntchito, kuwonongeka kwakanthawi kumatha kuchitika.

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P0703

Ngakhale vuto losinthira ma brake light ndi losavuta, limatha kutsagana ndi ma code ena omwe angapangitse katswiri kuthana ndi vuto la torque converter clutch solenoid kapena waya.

Kodi P0703 ndi yowopsa bwanji?

Khodi P0703 ikhoza kupangitsa kuti magetsi a brake asagwire ntchito kapena kukhalabe nthawi zonse, zomwe ndizowopsa. Zitha kupangitsanso kuti chosinthira ma torque zisatseke kapena kuti chotchingira chisatseke, zomwe zingayambitse kuyimitsidwa kapena zovuta zina zoyendetsa.

Ndi kukonza kotani komwe kungakonze P0703?

• Kukonza, kusintha kapena kusintha masinthidwe a brake light .

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P0703

Monga momwe zimakhalira ndi matenda ena, nambala ya P0703 imatha kuloza katswiri panjira yoyenera. Musanasinthire mbali zilizonse, ndikofunikira kutsatira njira zothetsera mavuto kuti muzindikire molondola nambala ya P0703.

P0703 ✅ ZIZINDIKIRO NDI KUTHETSA ZOYENERA ✅ - Khodi yolakwika OBD2

Mukufuna thandizo lina ndi nambala yanu ya p0703?

Ngati mukufunabe thandizo ndi DTC P0703, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
