Izvi zvinorevei?

Iyi generic Diagnostic Dambudziko Kodhi (DTC) inoshanda kune mazhinji OBD-II mota (1996 uye nyowani). Izvi zvinogona kusanganisira, asi hazvirevi kune, mota dzinobva kuToyota (Prius, Camry), Lexus, Fisker, Ford, Hyundai, GM, nezvimwe. Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana negore, gadzira, modhi uye kufambisa kumisikidza.

Kana yako yakasanganiswa mota (HV) yakachengeta iyo P0A7D kodhi, zvinoreva kuti powertrain control module (PCM) yaona isina kukwana mwero wezinga sezvo ichienderana nebheterti yemagetsi. Iyi kodhi inofanira kungochengetwa mumotokari dzakauchikwa.

Kazhinji, yakakwira voltage (NiMH) bhatiri ine masere (1.2 V) maseru akateedzana. Makumi maviri nemasere emasero aya anoumba HV bhatiri pack. Iyo yakasanganiswa mota bhatiri manejimendi sisitimu (HVBMS) inoona nezve kudzora uye kuongorora iyo yakakwira voltage bhatiri. HVBMS inopindirana nePCM nevamwe vatongi pazvinenge zvichidikanwa.

Cell resistance, bhatiri voltage, uye bhatiri tembiricha zvinhu zvese izvo HVBMS (nemamwe ma controller) anotariswa pakuverenga hutano hwebhatiri uye inodiwa mamiriro ekuchaja. Mota zhinji dzakasanganiswa dzinoshandisa HVBMS system uko sero yega yega ine ammeter/temperature sensor. Iyo HVBMS inotarisisa data kubva pasero rega rega uye inoenzanisa mazinga emagetsi ega ega kuti ione kana bhatiri riri kushanda pamwero waunoda kuchaja. Mushure mokunge data yaverengwa, mutongi anowirirana anoita maererano.

Kana iyo PCM ikaona huwandu hwemagetsi kubva kuHVBMS isingakwani mamiriro acho, P0A7D kodhi inochengetwa uye mwenje wekusashanda (MIL) unogona kuvhenekera. Mune zvimwe zviitiko, zvinotora akawanda kutadza kutenderera kujekesa iyo MIL.

Chii chakakomba cheiyi DTC?

Kodhi yakachengetwa P0A7D uye mamwe ese makodhi ane chekuita neHVBMS inofanirwa kutorwa seyakanyanya uye kurapwa saizvozvo. Kana kodhi iyi ikachengetwa, iyo yakasanganiswa powertrain inogona kunge yakaremara.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP0A7D kodhi kodhi inogona kusanganisira:

• Yakaderedzwa mafuta anoshanda
• Kuderedza kuita kwese
• Mamwe macode ane chekuita neakakwira voltage bhatiri
• Kuregererwa kwemagetsi emagetsi kuisirwa

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi kodhi zvinogona kusanganisira:

• Yakaremara yakakwira voltage bhatiri, sero kana bhatiri pack
• Inokanganisa jenareta, turbine kana jenareta
• HVBMS sensor kusashanda
• HV Bhatiri Fans Kwete Kushanda Zvakakodzera
• Yakasununguka, yakaputsika kana yakaora mabharaki ekubatanidza kana tambo

Ndeapi mamwe matanho ekutambudza P0A7D?

Kana bhatiri yekuchaja macode system aripo, ongorora uye uagadzirise usati waedza kuongorora P0A7D.

Kuti unyatsoongorora iyo P0A7D kodhi, iwe unozoda yekuongorora scanner, digital volt / ohmmeter (DVOM), uye HV bhatiri system yekuongorora sosi.

Tanga nekuona nemaziso HV bhatiri nematunhu ese. Tarisa zviratidzo zvekuora, kukuvara, kana maseketi akavhurika. Bvisa ngura uye gadzirisa zvisina kukwana zvinhu kana zvichidikanwa.

Shandisa iyo scanner kuti utore ese akachengetwa makodhi uye inosanganisirwa kuomesa furemu data. Mushure mekunyora ruzivo urwu, bvisa makodhi uye test drive mota. Kana zvichikwanisika, edza kutyaira mota kusvikira iyo PCM yapinda yekugadzirira mamiriro kana kodhi yadzimwa.

Kana P0A7D yadzoswazve, shandisa iyo scanner kuongorora HV bhatiri data data uye bhatiri chinzvimbo. Wana bhatiri bvunzo maitiro uye zvakatemwa kubva kune yako yakakwira voltage ruzivo sosi. Kutsvaga akakodzera echikamu marongero, wiring madhiagiramu, chinongedzo kumeso, uye chinobatanidza pinouts zvinobatsira mune chaiyo diagnostics.

Kana bhatiri rikaonekwa kuti harina kukwana: HV bhatiri rekugadzirisa rinogoneka asi rinogona kusavimbika. Nzira yechokwadi yekugadzirisa HV bhatiri paki yakakundikana ndeyekuitsiva nefekitari, asi izvi zvinogona kudhura zvakanyanya. Mumamiriro ezvinhu akadai, funga iyo chaiyo HV bhatiri paki inoshandiswa.

Kana bhatiri iri mukati meanoshanda mashandiro, edza akakodzera HVBMS (tembiricha uye magetsi) sensors zvichitevera izvo zvemugadziri zvirevo uye nzira dzekuyedza. Izvi zvinogona kuitwa uchishandisa DVOM. Tsiva ma sensors asinga sangana neyakagadzirwa magadzirirwo.

Kana ma sensors ese ari kushanda nemazvo, shandisa iyo DVOM kuyedza kuramba kwesero rimwe nerimwe. Masero anoratidza mwero usingagamuchirike wekudzivirira anofanirwa kunge aine zvinongedzo zvebhazi netambo dzakasimbiswa neDVOM.

• Akakundikana bhatiri maseru uye mabhatiri anogona kutsiviwa, asi yakakwana HV bhatiri kutsiva ndiyo inowanzo yakavimbika mhinduro.
• Iyo yakachengetwa P0A7D kodhi haingoitisa iyo HV bhatiri yekuchaja system, asi mamiriro akaita kuti kodhi ichengetwe inogona kuidzima.
• Kana iyo HV iri mubvunzo ine anodarika zviuru zana zvemamaira pane odometer, fungidzira chakaremara HV bhatiri.
• Kana mota yakafamba isingasviki mamaira zana, zvingangoita kuti kubatana kwakasununguka kana ngura ndiko kunokonzera dambudziko.
