Yuav hloov cov hlua li cas
Yog tias muaj kev cuam tshuam tsis tu ncua tau pib ua haujlwm ntawm cov khoom siv hluav taws xob cuam tshuam nrog kev xaim tsis raug, cov kws tshaj lij pom zoo kom hloov tag nrho cov xaim hauv lub tsheb. Ib yam yuav tsum tau ua tom qab yuav ib lub tsheb los ntawm tus tswv, uas tau hloov cov tswv yim, ntxiv lossis txhim kho ib yam dab tsi. Xws li cov kev hloov pauv cuam tshuam rau qhov tsis sib xws ntawm on-board network, piv txwv li, lub roj teeb yuav tso tawm sai dua, thiab lwm yam. Yog li ntawd, nws yuav yog qhov tseeb dua rau tus tswv tshiab coj txhua yam rov qab los rau nws daim ntawv qub.
Txhawm rau hloov cov kab hluav taws xob hauv tsev, koj yuav tsum:
- Tshem cov connectors ntawm lub mounting thaiv.
Txhawm rau pib hloov cov xaim hluav taws xob, koj yuav tsum tshem tawm cov khoom sib txuas los ntawm lub mounting thaiv - Tshem lub ntsuas vaj huam sib luag thiab pem hauv ntej trim.Cov kauj ruam tom ntej yog tshem tawm cov trim thiab ntsuas vaj huam sib luag.
- Tshem cov kab qub qub.Cov hlua qub yog unfastened thiab tshem tawm ntawm lub tsheb
- Txhim kho txoj hlua tshiab rau qhov qub.Txhim kho cov kab tshiab nyob rau hauv qhov chaw ntawm cov kav hlau qub.
- Restore lub trim thiab hloov lub ntsuas vaj huam sib luag.
Yog tias koj xav hloov cov xaim ntawm cov khoom siv hluav taws xob ntawm VAZ 21074, tab sis tsis muaj "haiv neeg" ntawm tes, koj tuaj yeem siv cov khoom zoo sib xws. Piv txwv li, rau "xya", ib txoj hlua hluav taws xob nrog cov ntsuas hauv qab no yog qhov tsim nyog:
- 21053-3724030 - ntawm lub dashboard;
- 21053-3724035-42 - ntawm lub ntsuas vaj huam sib luag;
- 21214-3724036 - rau roj injectors;
- 2101–3724060 — pib;
- 21073-3724026 - mus rau ignition system;
- 21073-3724210-10 - tiaj tus rear sam xauv nees.
Ib txhij nrog cov xaim, raws li txoj cai, lub mounting thaiv kuj tau hloov. Nws yog qhov zoo dua rau nruab ib hom tshiab mounting thaiv nrog plug-in fuses. Nws yuav tsum nco ntsoov tias, txawm tias qhov zoo sib xws ntawm sab nraud, mounting blocks tuaj yeem muaj ntau hom, yog li koj yuav tsum tau saib cov cim ntawm lub qub thaiv thiab nruab ib qho. Txwv tsis pub, cov khoom siv hluav taws xob yuav tsis ua haujlwm zoo.

Peb tshem tawm lub vaj huam sib luag thiab muab tso rau ntawm sly, tsis muaj dab tsi nyuab nyob ntawd. Ua ntej, peb txuas lub vaj huam sib luag thiab sab hauv, peb ncab lub braid nyob rau hauv lub hood mus rau qhov chaw ntawm lub block. Peb tawg cov xaim nyob rau hauv lub cav compartment: corrugation, clamps, kom tsis muaj dab tsi dai los yog dangles. Peb muab lub thaiv, txuas nws thiab koj ua tiav. Kuv kuj xav qhia koj kom muab cov terminals ib txwm tso rau ntawm lub roj teeb, cov khib nyiab tsis tu ncua (tsawg kawg ntawm tus qauv cuaj kab hluav taws xob). Thiab yuav ob pawg ntawm Czech fuses, tsis yog cov neeg suav tsis tuaj yeem.
Hluav taws xob faults VAZ 21074 - yuav ua li cas txheeb xyuas thiab kho cov teeb meem
Yog hais tias, tom qab tig tus yuam sij ignition, roj nkag mus rau hauv lub carburetor los yog VAZ 21074 txhaj thav duab, thiab lub cav tsis pib, qhov ua rau yuav tsum tau nrhiav nyob rau hauv cov hluav taws xob qhov chaw. Nyob rau hauv lub tsheb nrog lub cav carburetor, nws yog ib qho tsim nyog yuav tsum tau xyuas, ua ntej ntawm tag nrho cov, lub breaker-distributor, lub kauj thiab lub txim plugs, raws li zoo raws li txoj kev ntawm cov khoom siv hluav taws xob. Yog tias lub tsheb tau nruab nrog lub tshuab txhaj tshuaj, qhov teeb meem feem ntau yog nyob rau hauv ECM los yog hlawv cov neeg nyob rau hauv lub ignition switch.
Carburetor cav
Muaj lub tswv yim hais txog kev ua haujlwm ntawm cov tshuab hluav taws xob ntawm lub tsheb, nws yooj yim dua los txiav txim qhov ua rau lub cev tsis ua haujlwm thiab tshem tawm nws. Piv txwv li, hauv lub cav carbureted:
- ignition lag luam pib nrog tus yuam sij raug tsiv mus rau "Starter" txoj hauj lwm;
- Tom qab ntawd, lub tshuab hluav taws xob tau qhib;
- los ntawm lub tshuab hluav taws xob, lub teeb liab hluav taws xob yog siv rau lub kauj uas ua kom muaj hluav taws xob siab;
- los ntawm high-voltage nyob ntawm tej, qhov voltage ntawm lub kauj yog nkag mus rau distributor;
- Los ntawm tus xa khoom, hluav taws xob impulses raug xa mus rau cov electrodes ntawm lub txim plugs.
Yog tias lub cav tsis pib tom qab lub tshuab hluav taws xob qhib, qhov no yuav yog vim:
- tawg nyob rau hauv hluav taws xob Circuit Court ntawm lub coil thiab lub generator. Nws yog ib qho tsim nyog los xyuas qhov tseeb ntawm tag nrho cov kev sib cuag thiab xaim nyob rau hauv seem ntawm lub Circuit Court;
- coil winding tsis ua haujlwm. Txhawm rau kuaj xyuas kev noj qab haus huv ntawm lub kauj, koj yuav tsum tshem tawm lub hwj chim cable ntawm lub distributor, thiab nrog lub cav khiav, kov nws nrog "hauv av" hu. Yog hais tias lub txim tshwm sim ntawm qhov no, lub kauj yog zoo;
- cuam tshuam ntawm Circuit Court ntawm distributor thiab spark plugs. Nws yog ib qho tsim nyog yuav tsum tau hu xov tooj rau lub high-voltage cable nyob rau hauv cheeb tsam no thiab xyuas qhov tseeb ntawm lub slider nyob rau hauv lub distributor cover.
Yog tias lub tsheb siv lub tshuab hluav taws xob tsis sib cuag, ib qho hluav taws xob hloov hluav taws xob nruab nrab ntawm lub kauj thiab cov khoom xa tawm ntxiv rau hauv Circuit Court. Lub luag haujlwm ntawm kev hloov pauv yog kom tau txais cov teeb liab los ntawm qhov sib thooj sensor thiab tsim cov pulses siv rau lub hauv paus winding ntawm kauj: qhov no yuav pab tsim lub txim thaum khiav ntawm roj ntshiv. Kev hloov pauv tau raug tshuaj xyuas tib yam li lub kauj: sparking ntawm cov xaim xaim ntawm cov khoom xa tawm qhia tias qhov hloov pauv ua haujlwm.

Txhaj tshuab
Lub tshuab txhaj tshuaj yog pib vim:
- kev siv lub twj tso kua mis hluav taws xob, uas yog lub luag haujlwm rau kev tsim cov kev kub siab hauv cov roj system;
- tsim cov roj sib tov nyob rau hauv lub tog raj kheej (thiab tsis nyob rau hauv lub carburetor);
- roj txhaj tshuaj los ntawm hluav taws xob injectors;
- siv ECM, uas txiav txim siab lub sijhawm ntawm kev txhaj tshuaj roj rau hauv lub tog raj kheej.
Kev cuam tshuam hauv qhov hluav taws xob ntawm lub tshuab txhaj tshuaj feem ntau cuam tshuam nrog kev ua haujlwm tsis zoo ntawm lub sensor lossis cov xaim tawg. Txhawm rau txheeb xyuas qhov tseeb ntawm lub sensor, koj yuav tsum:
- Disconnect lub connector thiab tshem tawm lub sensor los ntawm lub rooj zaum.
- Ntsuas qhov tsis kam ntawm lub sensor.Tshem tawm lub sensor thiab ntsuas nws qhov tsis kam nrog multimeter.
- Sib piv cov txiaj ntsig nrog lub rooj, uas tuaj yeem pom hauv cov lus qhia rau cov khoom siv hluav taws xob ntawm lub tsheb.
Diagnostics ntawm malfunctions ntawm auxiliary khoom siv hluav taws xob pib, raws li txoj cai, nrog rau mounting thaiv. Yog tias muaj teeb meem hauv kev ua haujlwm ntawm lub teeb pom kev zoo, lub suab nrov thiab lub tswb nrov, lub rhaub dej, kiv cua txias lossis lwm yam khoom siv, koj yuav tsum xub xyuas qhov kev ncaj ncees ntawm lub fuse uas yog lub luag haujlwm rau ntu ntawm Circuit Court. Kev tshuaj xyuas fuses, ib yam li lub tsheb hluav taws xob hluav taws xob, yog ua los ntawm multimeter.
