Vaz 21041 30 technical. Features of the VAZ wiring and its replacement

This resonator is installed on VAZ 2104, 2106, 2107 Izhevsk assembly With injection motor and Euro-3 standards.

How to understand which resonator is installed on your car and distinguish one from the other?

As a rule, Euro-2 resonators were installed on cars manufactured before 2008. In 2008 and beyond, Euro-3 resonators began to be installed. But this information cannot be 100% trusted, so we will tell you how to visually distinguish Euro-2 resonators from Euro-3 on a VAZ 2104 assembly of IZH-auto.

If you put these 2 resonators side by side, you will see that Euro-3 is shorter than Euro-2 by several centimeters. But if your burned-out resonator is still on the car and there is nothing to compare it with, in order to understand which of the 2 you should choose, look at the catalyst, which is also a converter exhaust gases, to which the resonator is screwed (in the picture, the catalysts are replaced by inserts).


If you see a catalyst into which an oxygen sensor is screwed and on one of its sides there is a flange for 3 mounting bolts, then you need a Euro-3 resonator. If you see a catalyst that has a flange for 2 bolts on both sides and an oxygen sensor is not screwed into it, then you need a Euro-2 resonator.

The operation of any electrical equipment in a car is directly related to the performance of the wiring. If there are breaks in the circuit, this may affect the functionality of the equipment as a whole. From this article you can find out what a VAZ 21043 carburetor is with detailed description elements.

[ Hide ]

What is included in the electrical circuit?

The VAZ 2103 or 21041 scheme, regardless of the ignition system used, includes the following elements:

• battery, the negative output of which is connected to the body;
• starter;
• regulator relay;
• BP - a block with fuses designed to protect equipment from short circuits and high voltage;
• generator, which is one of the main components of the VAZ wiring;
• ignition switch.

On any VAZ car, negative outputs from energy consumers are output to the mass, namely, to the car body. The car body itself is an excellent conductor. But as for the wired connection, it should be borne in mind that it is provided only with positive wiring. Above is a VAZ 2104 and VAZ 2103 diagram with all electrical circuits and the designation of all elements, and below is a table that indicates the purpose of all relays.

Signs of inoperability of the electrical circuit

Wiring VAZ 2104 is weakness, constantly something does not work. Since the production of cars of this model was discontinued many years ago, often VAZ car owners with a carburetor or injector are faced with the problem of equipment inoperability. If the electrical equipment began to work incorrectly, the motorist needs to diagnose the circuit. Always remember that when carrying out electrical wiring repair work, the system must always be de-energized. Checking the performance of certain devices is carried out on the basis of studying the circuit.

If you notice that there are problems with the electrical circuit, the vehicle can operate in one of two states:

1. If the car cannot move and does not even start, then in general possible causes, according to which this happens, there are many. In such cases, first of all, the diagnostics of the operability of the distributor and starter are carried out, it is also necessary to check the charge battery. IN winter time years, owners of "fours" with old batteries often face a similar problem as a result of a complete discharge of the battery. As practice shows, a complete failure of the generator happens much less frequently, however, the performance of this device also needs to be checked.
2. The car can start and even drive, but there are malfunctions in the operation of the equipment. Problems can also be very diverse - and short circuits, and breaks, and failure of the fuse, and breakdown of the equipment itself. It would seem, why not at the same time, wipers cleaning windshield, rear view heating? At first glance, these elements are not connected in any way, but it is worth remembering that they all work when the ignition is turned on, and everything falls into place.

According to experts in the field of wiring repair, the first thing to do is to check the ignition switch device, as this component is designed to:

• control of all the functionality of the ignition system;
• alarm management vehicle(video by Edward Deviatkin).

Troubleshooting

So, if you want to check the performance of all elements of the wiring diagram, you must follow certain steps. If there are problems in the operation of the equipment, then first of all it is necessary to check whether the fuses installed in the unit are working. If everything is in order with the fuses, but, for example, the optics do not work, then you will need to check the lamps. If everything is normal with them, then the wiring is dialed using a tester.

In the event that the car does not start at all, you will need to perform the following steps:

1. First, check the battery, as mentioned above, a full discharge may make it impossible to start the engine.
2. If the battery is charged, you need to ring the section of the circuit from the ignition coil to the generator. It often happens that breaks are to blame. If breaks are detected in the wiring diagram, it is necessary to replace the wires. If you notice that there are oxidations on the contact contacts, then they must be eliminated. To do this, the contacts are either changed or cleaned.
3. If the coil does not spark, the engine will not start. To check if there is spark, pull high voltage wire and bring it to the mass, that is, to the iron (body, for example). Your assistant at this moment must turn the starter to start the internal combustion engine. At the time of the start attempt, a spark should flash between the wire and the ground.
4. Troubling the engine and the inability to start it is often associated with the operation of bad spark plugs. hinder normal operation power unit can deposit and plaque that appears on the electrodes. Accordingly, with too much plaque, the appearance of a spark will be impossible. To solve the problem, it is necessary to clean the candles, detailed instructions You .

1. Security. How do I know how safe a 4 is? IN serious accidents I didn’t have a chance to get into my life, so I put a C grade for the lack of airbags and an easily crushed body with a displaced frontal impact.

2. Comfort suits me quite well. With a height of 187 cm, I am quite comfortable behind the wheel. Once I drove 250 km without stopping (the length of the road that day was 498 km). At average speed 75 km/h is 3.5 hours. It's time to stop. When I got out of the car, to be honest, my body was tired. I DO NOT BELIEVE those who say that it is supposedly different in other cars. Well, I have never been able to sit in one place for 3 hours and get up as cheerful - neither on the train, nor on the bus, nor as a passenger in the car, nor on the couch at home. A person, even when sleeping, turns over from time to time, because. body in one position becomes numb. In general, at long distances I try to make stops every 150-200 km. Go to the toilet, inspect the wheels, etc. I rated four for the fact that sleeping on the unfolded seat is not very comfortable - you won’t get enough sleep.

3. Driving performance. Enough soft suspension, does not knock. In terms of cross-country ability - I think that 90 percent of the vehicle's cross-country ability depends on the specific driver. I don’t consider myself a teapot, I don’t consider myself a super driver either. Average. I got stuck several times more due to inexperience, if I had more experience - I would not call in where you can’t get out. And so, on the rear wheel drive, I parked in knee-deep snow, where no one poked at all, and in the morning I drove out of this snow, and a lot of things happened. In difficult situations, the main thing is to keep the front wheels straight and be able to rock the car with the clutch. Score four for large radius reversal.

4. Reliability. It always started (even at -32 on 10w40), always drove where it was needed. And in general, there were no serious repairs. Suspension regularly inspect and diagnose. The car is already over 38,000, no backlashes were found in the suspension, although I drive not only on asphalt.

5. When you wash it - very beautiful, everything shines, black. And when it’s dirty, filthy, you don’t even want to look, sit down and go faster.

A few words about myself. By profession, a mechanical engineer. I've been renovating for a long time. industrial equipment, starting with hand-held power tools and ending with modern glass-forming sectional automatic machines the size of a tram and weighing 42 tons. I am well versed in mechanics, electricity, not bad - in electronics, pneumatics and hydraulics. I have a slightly different vision of technology than ordinary users.

So, actually a review. I'll clarify right away that the car is not mine - it's official. I drive it 95% of the time, so I look after it myself. When we decided to take a car, we considered several options - Renault Kangoo, VAZ 2104, VAZ Oka, VAZ 2131. Renault was dropped as the most expensive option. In addition, I did not want to learn how to drive a foreign car: if something happened, you would be left without pants. They didn’t take the eye, because it is no longer produced, there was no confidence in its reliability, and with spare parts, they say, it’s a bit tight. Niva eats a lot of fuel. In the end, we settled on four.

They took it with a range of 1347 km from a man who inherited it from his nephew for recycling. He went on it only for fishing. Decided to sell because he was diagnosed with cancer, it was not up to the car. With a cost at that time in the showroom of 223,000, we took it for 185. Car mats, a tool bag, a foot pump and a bucket with a rag were attached to the car. Purchased a week after purchase Winter tires Kama with stamped Togliatti disks and operation began. Already learned to ride winter roads. Thanks to an elderly partner who constantly sat next to me. He told a lot, showed a lot.

The car for all the time has never failed so that it was impossible to go. At the very beginning, the 7.5 A fuse in the ignition coil power circuit burned out 3 times. This happened at intervals of about 5000 km. Now it has stopped burning. I don’t know, maybe water got in, maybe I didn’t remove the coil, I just changed the fuse and drove on. Once I had to tighten the alternator belt. Inconvenient design. No tensioners are provided - you have to pull the generator with a mount. Now in frosts sometimes whistles during warming up. To the touch, the stretch is within the normal range, I sin on the thickened grease in the generator bearings, heavy load and a worn belt.

By 25 thousand, I realized that the oil was leaving the engine somewhere. It turned out that through the gasket pan. Stretched with the help of a cardan head. Now everything is dry underneath. In January 2012, after operating at -35, the liner seal began to leak cardan shaft in the gearbox. The whole bottom was splattered with oil. I thought it was completely gone. He did not change himself, because. wallowing in the snow at -15 is not much fun, especially a company car. I took it to the service. Oil + oil seal 270 rubles, work 480 rubles. They did not change the oil completely, they just topped it up. Once I arrived at night from a business trip, unloaded the car and suddenly ... the rear right door does not close! There is no alarm, they will climb in and you will not recognize. What to do? He pressed the door against the wall of the house and calmly went to rest. The next day, I disassembled the M8 nut in the lock mechanism. 20 minutes + two screwdrivers + wrench and all hockey! I installed the radio and speakers myself. At minus 15. A business trip of 170 km was planned, I didn’t want to go, listening only to the whistle of the air and the hum of the engine. I didn’t have time to put the speakers then, I had to throw it into the glove compartment. So they yelled all the way from there. Once I tightened the front wheel bearings, I felt a slight backlash.

One night on the bank of the river, handing back, rested the exhaust pipe in a pile of gravel. After that, there was a clanking sound from under the car. Turns out exhaust system deformed and the first muffler began to touch the cardan. Pulled and tied with wire to the bracket of the right mudguard. So it rides for now. I'll take care of it in the summer.

Once on the M5 highway, at the Bavlinsky crossroads, at night, I flew into right side into the pit. If I were more experienced, I would go out and see what happened to the wheels. But I didn't even think about it and just kept going. Kilometers through 70 I feel - rear right wheel drives on asphalt. It turns out that the rim was bent and the wheel began to slowly lower. The result - a tire to shreds and a wheel change at one in the morning on the side of the road in rain and strong wind.

Recently, with a run of just over 38 thousand, it started - the engine began to triple, you release the clutch - it stalls, there is not enough power to turn the box. I tried a couple more times and it didn't work. I had to change the candles (the first time at all). With new spark plugs, it worked fine, only the yellow "check engine" light was on. I thought to go to the service, so that they connected to the computer. But that day there was a lot of work, not before. The problem was solved by itself - after 30 kilometers the car jerked, the light went out, and the power increased. It would be great if all the problems so eliminated themselves!

Just eliminated the problem of gathering-collapse. At one time the car pulled a little to the left. I still couldn't get to the service station. Now for 10 thousand as it does not pull. Looked rubber does not eat, well, okay. Apparently tired of waiting for me :-). I have never touched a valve either. By indirect evidence, I think that there is nothing to meddle in there. In general, I think that if you don’t climb, you won’t break. The human factor is a very common cause of equipment failures.

I change oil every 10 thousand. Air filter along with oil, but I don’t touch the fuel one. It is immediately felt when you change the vozduhan-machine not to be recognized. Cruising speed it becomes 110 km / h, and overtaking is a pleasure - in 3rd gear the car just shoots. Closer to 5-6 thousand, a loss of power is felt, optimal speed- 90 km/h. I change the oil like this - after the trip, while the engine is hot, I drain it, as it merges, I start the engine and let it run for 20 seconds to drive the remaining oil out of myself. After that, I leave it overnight. I fill it fresh in the morning. ELF 10w40 in summer, ELF 5w30 in winter.

In general, the unfortunate car was caught in terms of accidents - the body was already beaten on trifles 4 times. The last time it was quite a shame - I was walking along the M7 highway at a speed of 90 at night. Before this was heavy snowfall, but the track, although it was cleaned, sharp maneuvers were undesirable. Suddenly I saw a snowball in front of me - probably fell off the truck. I was afraid to dodge, so as not to fly off the road. I decided to go as I was driving. As a result, the skirt under the bumper was bent with right side. I'm glad that the Zhiguli would have a plastic bumper, like on modern cars would have to change it. And so you can bend and tint, where the paint flew off, anyway, you can’t see it from below.

There are doubts about the omnivorous Zhiguli. I refueled a couple of times at the left gas stations, so you immediately feel that octane number a little, a little more pressure on the gas, detonation, you can hear the engine ringing. I had to accelerate slowly. In terms of consumption - on the highway at 90 km / h with five passengers and a full trunk, as well as a roof rack, the car requires 6.8 liters per 100 km. The average consumption is 8.9 per hundred in highway / city 50/50 mode.

That's all for now. Thank you for your attention, I wish you all a safe ride.

In the early 80s, in order to replace the VAZ-2102 station wagon, which was already outdated by that time, the specialists of the Volzhsky car factory started designing new car. The designers were faced with the task of creating new station wagon at the lowest cost and maximum effect. The VAZ-2104 sedan was taken as the basis of the car, which had to be redone. As a result, in the second half of 1984, a new station wagon from the VAZ automobile plant was born with the factory index VAZ-2104, or simply “four”.

Station wagon VAZ-2104 was completed various engines, including diesel engine VAZ-341. Over time, after another upgrade, the car received a 5-speed gearbox.

Compared to the previous station wagon, the VAZ-2104 had a number of advantages and by 1985 it completely replaced the “two” from production, so for the next 15 years the car was the only station wagon of Togliatti production until the appearance of the VAZ-2111. In 2003, AvtoVAZ ceased production of the VAZ-2105 station wagon, but from that moment until 2012, Izhevsk Automobile Plant continued its production.

Design and construction

Compared to the VAZ-2105 sedan, on the basis of which the VAZ-2104 was created, the station wagon received less rigid body. After lengthening the roof, stampings appeared to increase rigidity, however, the resulting rigidity was not enough and in order not to flush the roof, it was not recommended to heavily load the trunk located on it. In the rear of the car, for access to the trunk, an upward opening door was placed, the glass of which, unlike the previous station wagon, received heating and a wiper.

The interior of the VAZ-2104 station wagon was exactly the same as that of the VAZ-2105 sedan, with the exception of rear seats, which, as it should be for station wagons, could be folded, thereby increasing the volume luggage compartment. Trunk volume was 375 liters by default, and when the seats are folded, increased to 1340 liters, thereby allowing you to carry oversized cargo weighing up to 455 kilograms. Among the shortcomings, it can be noted that it was much more difficult for a standard heater from a sedan to warm up a significantly enlarged interior in the cold season.

As a power unit, the VAZ-2105 station wagon was equipped with exactly the same engines with a volume of 1290 to 1689 cm3 and a power of 64 to 84 Horse power. But, despite the fact that the engines were the same, the speed of the station wagon was lower (137 km / h instead of 143) due to the less streamlined shape of the tail. Since 1999, a small-scale modification of the station wagon with the factory index VAZ-21045D was produced, which was equipped with a VAZ-341 diesel engine with a volume of 1.52 liters and a power of 50 horsepower. The diesel station wagon was much more expensive, but given that at the time diesel fuel cost much cheaper than gasoline, the operation of this modification was cheaper.
