Maitiro ekuyedza PCM ine multimeter
Zviri mukati
Mota dzakagadzirwa mumakore anhasi dzakabatsira kuita kuti hupenyu hwedu huve nyore. Zvinhu zvemagetsi mazviri zvainyanya kubatsira.
Iwe unogona sei kudzora injini uye kutapurirana, pamwe nemamwe masisitimu emotokari, nekudzvanya kuri nyore kwebhatani? Zvakanaka, zvine chekuita nePCM (Powertrain Control Module).
Ichi chinyorwa chinokurumidza kujekesa zvimwe zvezvinhu izvi zvaunofanira kuziva uye kuti ungangoshandisa sei multimeter kuongorora. Ngatitangei.
Chii chinonzi PCM mumotokari?
Iyo yakabatana controller yako Engine Control Unit (ECU) uye Transmission Control Unit (TCU), maviri akakosha einjini makomputa. Iyo inozivikanwawo seiyo ignition control module (ICM) kana injini yekudzora module (ECM).
Nekudaro, sekunge chero chimwe chikamu chemagetsi, matambudziko nePCM yako zvinozoitika kana zvinogona kuitika; dzimwe dzakakomba kupfuura dzimwe.
Zviratidzo zveMhosho PCM
Usati wanyura mumasisitimu emota yako kuti uise maoko ako muPCM yako, unofanirwa kuve nechokwadi kuti haisi kushanda. Heano zvimwe zvezviratidzo zvinoratidza PCM isiri kushanda;
- Mwenje yekuyambira yakabatidzwa. Izvi zvinosanganisira "cheki injini" chiratidzo, traction control chiratidzo, uye ABS chiratidzo.
- Kukanganisa kana kudzorera injini kushanda
- Kunyanya kupera uye kuwedzera kushandiswa kwemafuta
- Kunetsa kutanga mota sezvo ichindandama kana kusatanga zvachose
- Kutarisira matayi asina simba
- Bad gear transmission
Izvi zvinongova zvimwe zvezviratidzo zvakawanda zvinoperekedza yakaipa PCM. Zvisinei, izvo zvataurwa pamusoro apa zvinowanzoitika uye zvinoratidza dambudziko.
Kutarisa PCM ine multimeter
Zvino zviri pachena kuti multimeter inoita basa rakakosha mukuyedza PCM yako. Nekudaro, ichi handicho chega chishandiso chauchazoda. Mamwe emamwe maturusi akakosha ekuongororwa kwakaringana uye akazara anosanganisira:
- crosshead screwdriver
- Flashlight
- OBD kodhi scanner uye
- PCM itsva kana iwe uchifanira kutsiva PCM mune yakaipisisa kesi
Kazhinji, multimeter inonyanya kukosha kana uchitarisa bhatiri uye system wiring yezvinetso. Asi usati watanga navo, unofanira kutora matanho ekutanga;
- Ita ongororo yekuona
Kuongorora kwekuona ingori cheki chejini uye masisitimu ekukurumidza kuwana matambudziko epamusoro. Nekuita izvi, iwe unoda kuterera kune waya dzako.
Iwe unotarisa kuti uone kuti waya dzako hadzina kubviswa uye hadzina ngura uye ngura.
Iwe zvakare tarisa kune yakawandisa ngura pabhatiri kana PCM pachayo. Kuora kwakanyanya paPCM kunoreva kuti ungangoda kutsiva iyo PCM yese neitsva.
Pavanenge vasimbiswa, unoenda kune nhanho inotevera, uye apa ndipo panouya multimeter.
- Ongorora bhatiri
Kuedza kwebhatiri kunonyanya kuenderana nebhatiri yekuchaja voltage. Yakaderera bhatiri voltage inogona kukonzera sensor malfunctions inokanganisa PCM mashandiro.
Kuziva dambudziko pano kunokuchengetedza kushushikana kwakawanda.
Zvaunoita ne multimeter kutarisa kuti bhatiri voltage inenge 12.6 volts kana injini yadzimwa uye anenge 13.7 volts kana injini iri.
Kana mhedzisiro yako iri negative voltage, heino gwara rekukurumidza rekugadzirisa sei.
Kana kuverenga kunodonha pasi pe nhamba dzataurwa pamusoro apa, unoramba uchichaja bhatiri uye uiedze zvakare.
Paunenge uchiyedza bhatiri, unoisa iyo multimeter ku15 kana 20 volts, zvichienderana nezvainazvo. Iwe unobvisa imwe neimwe bhatiri plug uye wozobatanidza zvinotungamira kune mabhatiri anobatika.
Tsvuku inotungamira kune yakanaka bhatiri terminal uye dema inotungamira kune yakaipa bhatiri terminal.
Heino vhidhiyo inopenda mufananidzo wakajeka weizvi.
- Shandisa OBD kodhi scanner
Kana matanho ari pamusoro apera pasina nyaya, iyo OBD Code Scanner inouya mukutamba.
NeOBD scanner, iwe unotarisa mota yese yeOBD kukanganisa makodhi. Iwe unongoiisa mumotokari yako uye uverenge macode.
Kune akati wandei OBD zvikanganiso zvine zvazvinoreva zvakasiyana, saka iwe unoda mukana wekuzvidudzira kungave kuburikidza nekodhadhi kana zvakananga kubva kuGoogle.
OBD kukanganisa makodhi anoratidza zvese zvemakanika uye matambudziko emagetsi. Kuwana kodhi ine hukama nePCM yako kunoderedza huwandu hwekukanganisa uye kunoita kuti kuongororwa kuve nyore.
Semuenzaniso, dambudziko rekodhi P0201 rinoratidza kuti PCM ine dambudziko nejekiseni yejekiseni ye cylinder 1. Izvi zvinokonzerwa netsvina-yakazadza mafuta injector, mafuta injector corrosion, wiring corrosion, kana kushamwaridzana kusina kunaka.
Zvadaro kugadzirisa kwakakodzera kunoitwa.
Pamwe chete neP02 kukanganisa makodhi, P06 kukanganisa makodhi zvakare akajairika PCM ane hukama makodhi.
Ehe, kana iyo OBD scanner isingape kodhi yekukanganisa inonongedza kuPCM yako, uri kutendeudzira pfungwa dzako kune zvimwe zvikamu zvemotokari yako.
Kushandisa OBD scanner hakuna kuoma sezvaungafungidzira.
- Ongorora ma sensors ako uye wiring
Zvino, iyo multimeter zvakare yakakosha pano, uye zvinhu zvinogona kunge zvakati kuomarara zvichienzaniswa nematanho apfuura.
Uchishandisa multimeter, iwe unotarisa masensa akabatana nePCM uye yavo yakabatana wiring. Iwe unotarisa kwakashata multimeter kuverenga uye shandura chero chikamu chiri kuita matambudziko.
Iwe zvakare tarisa waya dzepasi uye zvese zvinongedzo zvakabatana nazvo. Iwo matsotsi chaiwo.
Kana matambudziko awanikwa pano uye shanduko dzichiitwa kune aya masensa, iwe wobva waisa patsva macode emota yako uye tarisa kana zvese zviri kushanda nemazvo.
Ko kana zvese izvi zvikasagadzirisa dambudziko rako?
- Dzorera PCM yako
Iri ndiro danho rekupedzisira raunotora. Pano uri kutsvaga rubatsiro rwehunyanzvi kutsiva PCM yako yese uye ita shuwa kuti PCM itsva yaunotenga inonyatso kuenderana nemotokari yako.
Ichagadzirisa zvese here?
Rangarira kuti iwe unofanirwa kuve nechokwadi chekuti PCM yako ndiyo honzeri huru. Kana zvisina kudaro, zvinosuruvarisa, matambudziko nehurongwa hwemotokari yako anogona kuramba aripo.
Nekudaro, kutevera nhanho idzi nekuchenjerera nemultimeter kunovimbisa kuti zvese zvine chekuita nePCM zvinogadziriswa.
