Kotushka fired VAZ 2110 8 valve carburetor. Unpinning, wiring diagram and checking the cat and burning the vases. Instructions as supplied

Every gasoline engine car has a ignition system. Without it, the work of such an engine of internal combustion (IHC) is impossible. The whole point is that a spark is needed to start the gasoline tank in the cylinders of the diesel engines. Slide indicate what for diesel engines such a system is not needed.

The classic version of the ignition system (SZ) includes:

• - battery;
• - lock with key;
• - pererivach;
• - dispenser (at the same time as the breaker, in the old SZ there were boules in one building, or just one name - distributor);
• - high-voltage conductors;
• - candles are lit.

The operating principle of the 3Z is based on electromagnetic induction. From the battery, through the ignition lock, the voltage is supplied to the primary lance of the ignition coil (SC). When the contact group of the breaker is in a closed state, a magnetic field is created. When the magnetic field is opened, the magnetic field disappears and a pulse is generated, which generates a high voltage at the secondary circuit of the short-circuit winding. The distributor from the secondary lance supplies high voltage to the spark plugs at the required moment. A spark runs between the electrodes, igniting the combustible mixture.

In modern internal combustion engines, the firing system began to look much different, but the principle is the same. The breaker and distributor were replaced with an electronic control unit. Before speaking, such a block, next to the ignition, is simultaneously fired by the robot of the ignition system. Cylindrical coils are no longer likely to stagnate, their firing modules have been changed. Modules can be in different configurations: one module for two cylinders or for several cylinders. And systems whose high-voltage darts were burned off. In such a model, the module fits right up to the spark plug, and the number of coils matches the number of cylinders of the combustion engine.

Kotushka (module) VAZ-2110

The coil works on the principle of a pulse transformer, converting low voltage to high voltage. In a secondary lancius, the voltage can reach forty thousand volts. Despite such high pressure, the life of an adult person is not unsafe, since the stream that flows through the Lanzug is negligibly small. Tim is no less, it is already unacceptable to be hit by a string from the wire of a candle.

The first models of VAZ-2110 cars were equipped primarily with carburetor engines and the coils on them were of the cylindrical type. Next, the “tens” took over the injection engine. The ignition system has also changed - the ignition module has replaced the old boiler.

The current ignition module VAZ-2110 has a monolithic body, in the middle of which two coils and a switch are sealed. This is a variant of the module, in which the switch is surrounded by a device - the body has two coils. The skin has two high-voltage outputs, a total of 4 such outputs. On the side of the module there is a connector to which low-voltage power is supplied.

Malfunctions of the VAZ-2110 firing module

If the engine starts running intermittently or fails to start, the cause of the problem may be the ignition module.

Characteristic signs of malfunction of the VAZ 2110 firing module:

• - lack of engine tension,
• - when accelerating, the car burns,
• - do not perform either 1 and 4 or 2 and 3 simultaneously,
• - The engine does not start.

Please note that on the VAZ-2110 one of the coils is responsible for the operation of cylinders 1 and 4, the other - for cylinders 2 and 3. When one coil is removed, the fire in the middle of the monolithic block stops firing two cylinders at a time.

A malfunction of the VAZ-2110 module can be detected in several ways.

Before we go, we need to take a look at the ignition module. The presence of cracks, burns and chips is unacceptable. However, engine failures occur for other reasons; with such defects, it is better to replace the part immediately - however, it will not last long.

Another method is to use a designated spark on the cylinder you are planning to use. It is possible, but there is a suspicion that the other cylinder is not working. Take a spare, working spark plug and connect it with a high-voltage wire to the coil. Place a spark plug near the engine block and start the engine. If the spark does not jump between the electrodes, it is likely that the module coil is faulty. The cause of the defect may be a high-voltage dart. When changing the wire from the working cylinder to the non-working cylinder, it is easy to switch over from your reference.

The third method is to check the support of the module coil windings with an ohmmeter. If the support increases due to the values ​​​​set by the factory that are greater than permissible, the ignition module requires replacement.

In case, if the engine does not want to start at all, it is easiest to check the fault with a subordinate operating module. It won’t start with it – well, I think the reason is different.

Please note that the VAZ-2110 ignition module cannot be repaired and must be replaced if defects are detected. And from now on you will need to keep such a part in stock - it will definitely not be sold.

The design of the car engine cooling system includes great quantity parts, components and elements. Of course, the skin plays an important role in the nutritional functioning of the car’s engine. In some situations, there may be a loss of voltage on the cylinders or some of them. The legacy of such a situation is the issue with the ignition module in the car. The problem is particularly relevant in cars produced by the Volzhsky plant, especially the VAZ 2110 model. It is worth saying that to identify this problem, it is necessary to check the VAZ-2110 firing module with a multimeter.

It is important that it is not necessary to replace the firing module again. Perhaps the components can be repaired. Of course, it is necessary to start diagnosing a technical node right now.

Firing module

Let's try to understand that The design of the VAZ 2110 ignition module(8 valves, injector). Also, according to its design, the wine consists of the following elements:

1. Two cats are fired.
2. Dual-channel type switch.

It is necessary to note that the ignition coils in this stage are necessary in order to generate high-voltage pulses and the spark plug that is directed.

If we talk about the reasons for the breakdown, the stench can be different. The most common cause is an interruption in the power supply to the engine. A smaller and more serious problem is the problem with the power unit. Indicator for checking the engine of the car, in which case it does not work.

Extended breakdowns

The process of diagnosing faults is not a serious problem. It’s crazy how much these Vlasnik cars are worth, who would like to understand a little about electrical equipment and use a multimeter. In this case, if there is a need for knowledge during the day, it is recommended to contact qualified specialists. Checking the VAZ-2110 firing coil (8 valves) with the help of an additional device like a multimeter allows you to get the required verification result.

There is no need to rush to install repair robots. The truth is that the problem may not lie in any element at all. Before you carry out verification of the firing module, you must consult a qualified specialist and, as a result, carry out verification of the transport service. When you use this procedure, you will spend more for everything penny koshti It's time. Before checking the unit, make sure that all other engine systems are functioning as required.

Often, in transport service There are breakdowns that are always caused by power forces. The indicator does not detect such faults. If you talk about the controller, then you will lose the stench. If you try to read pardons and use the help of a tester, you will not be able to identify them.

What are the signs of getting out of trouble more or less clearly. Let's talk about cause problems, then first for everything, you can bring them up to:

1. Contacts that were obstructed.
2. Finish the nasty strengthening of the mass.
3. A change has appeared that is electronic in nature.

Vikonanny repair robots

The biggest problem for the VAZ-2110 car is the situation when there is no voltage in two cylinders. After the singing hour, the engine begins to work again. In this case, it occurs after the back plate on the module has been pressed. Absolutely, regularly going through this procedure regularly is not correct. In fact, it’s better to diagnose the block, and then replace it with a warehouse or a replacement.

How to dismantle the heating module

Dismantling the module is a very complicated procedure. Sometimes it is necessary to understand the algorithm of action. Well, it’s like this:

1. Take care of the battery.
2. Removing the dry plate on the engine.
3. Dismantling darts placed on fire candles.
4. The selected part from the module.
5. Connect the connector to the module.
6. Tightening the nuts of the fixing blocks.
7. Careful dismantling, which allows for replacement.

Checking the firing module of VAZ 2110

Now let's try to understand that what kind of work is done with this component? The core must be formed using a plate made of aluminum. Any tool, for example a screwdriver, can get stuck here. Here it is necessary to take into account the fact that there is a small circuit board with electronic elements. To avoid damage during the process, it is necessary to cover them with additional silicone. It will be known in the future.

Then you need to remove all the arrows. There is no need to be afraid to complete this procedure; the remaining wiring will be replaced. The next step is soldering to the main wiring board. It’s easier to solder to the collectors of the transistor; the stink fragments are covered with a special ball. To resolve the problem, you need to remove the dead ball. After the soldering has been finished, cover the soldering area with additional varnish. After checking the module and making sure everything is functioning, you need to cover the surface with a special sealant. Then it is necessary to remove the folding robots from the turnaround order.

The bottom line of this procedure is that it doesn’t work in a simple way. In this case, it is necessary to select it carefully and correspond to the algorithm of action. We should give special respect to the way the soldering is completed.

It is guaranteed that the robot will be carried out correctly

Despite the obvious simplicity of checking the VAZ-2110 firing module (injector) and making repairs, not all people can carry out the work independently. If you do not have the necessary skills to carry out similar works It is recommended to work with qualified facists. It is not very difficult to find such fakers; most of the diagnostic and repair services can be obtained from a skin service center.

Most often, when the right approach Until then, it is possible to identify the cause of the breakdown and replace it in a short hour. In addition, masters who work at the service center may soon have information about the technical features of the VAZ-2110 heating coil (8 valves, injector) or information about other power supplies that fail.

It is worth saying that when choosing a service center where work will be carried out, it is necessary to give preference to the expertise of specialists with confidence. Regardless of the simplicity of Vikonannya's work, the master can give little evidence to Vikonannya's procedures. In this manner, after repairing the car, you can proceed, but you won’t end up in trouble. This moment also needs to be taken into account and guarded at the time of choosing a technical service station. If you get to the food without fail, then the problems will not go away.

A common cause of failure of the firing module is interruption in the functioning of the engine.

Engine firing coil- this is the main part of the car’s ignition system, which serves as the primary converter of a steady stream of low voltage that comes from the battery or directly from the electric generator high voltage voltage for further supply of an electrical impulse to the spark plugs.

The cat is, figuratively speaking, the “heart”, which ensures the creation of high tension in it. This detail is vikorized by everyone current systems burning: electronic, contact and non-contact. The coil is fired, as a matter of fact, by a transformer with two windings.

This voltage changeover is often called by car enthusiasts in everyday life "bobbin".

Keep in mind that this car part has a reliable design, and obviously it rarely goes wrong. The main malfunctions include:

• shaving of the secondary winding;
• Vitkova zamikannya kotushok;
• I break the caps.

The presence of a burnout crack indicates that the cover is broken. Shaving and coil shortening can be attributed to the support of the coils that will help the vimir. In the face of such a need, for example, repairing the boiler is not easy - you just need to buy a new one.

The price of a steaming cat for VAZ

The availability of this warehouse heating system for VAZ cars today is not great. Uzhivani can be bought for 150-200 rubles. The price of a new “bobbin” for a VAZ 2101 car (B-117 St. Oskol “6”) is 450 rubles, for a VAZ 2108 (027.3705 St. Oskol “6”) - 490-500 rubles and more.

A good new igniter K100 2108-3706010 (pictured above) for carburetor engines of VAZ 2108, 2109, 21099 (Lada Samara), 2110, 2111, 2112 costs 650 rubles.

The price of the ignition module 042 VAZ 2110 SOATE (photo above) in Russia is 1500 rubles.

Removing and replacing the boiler

In this case, there are cracks on the plastic surface of these parts, which, due to wear or overheating, require replacement. To switch off the low-voltage voltage, you will need keys 8 and 10.

Procedure for properly replacing the heating coil:

1. First, turn off the engine of the car and disconnect the wire from the “–” terminal of the battery.

2. After this, it is necessary to remove the central high-voltage wire from the “bobbin”.

3. Then you need to unscrew the two fastening nuts with an “8” wrench and insert two darts into the terminal of the coil.

4. At this stage, you need to unscrew one nut with a 10mm wrench and loosen the other nut securing the part to the bracket.

5. This message can be removed.

6. Replacing the heating coil of a VAZ car with a new one is done in the same order as for the gates, in addition, the blue wire must be connected to the “B” terminal, the red wire to the “K” terminal.

Checking the cat and burning the VAZ

Standards for boiler parameters for temperature dovkilla, which is above +25 °C, it is necessary to respect the lower indicated indicators. If, after checking the electrical part, its parameters do not correspond to those shown below, the device will need to be replaced.

The procedure for checking the bobbin:

1. In front of us, take it out of the car.

2. If this is not possible, you can check the heating coil without removing it from the machine. To do this, after connecting the terminal to the “–” terminal of the rechargeable battery, it is necessary to switch the voltage from the wire terminals (red and blue), and also to disconnect the central high-voltage wire.

3. To carry out the verification, the support of the primary winding of the coil must be connected to the low-voltage terminals of the coil with an ohmmeter. With this in mind, the coil has 3122.3705 (0.43±0.04) Ohm, and 8352.12 - (0.42±0.05) Ohm.

4. In order to check the supports of the secondary winding of the coil, connect the ohmmeter to the low-voltage terminal “B” and the high-voltage terminal of the converter. The support for 3122.3705 is due to more than (4.08±0.40) kOhm, and for the coil 8352.12 - (5.00±1.00) kOhm.

5. To check the insulation support to ground level, you need to connect an ohmmeter through the skin terminal and to the casing of the heating coil. The ohmmeter in all cases may indicate a reading that exceeds 50 MOhm.

Elements of the VAZ-2110 ignition system

The VAZ-2110 firing system is contactless and microprocessor based. This section has a non-contact heating system. It consists of a distributor, a switch, an ignition coil, a candle, an ignition extinguisher, and high- and low-voltage wires.

Fig.28. Scheme of the contactless firing system for the VAZ-2110

1 – rechargeable battery; 2 – generator; 3 – plug socket; 4 – vimikach zalyuvannya; 5 – sensor-socket; 6 – switch; 7 – candles; 8 – the cat is fired.

Ignition dispenser (distributor) VAZ-2110 type 40.3706 or 40.3706-01, with sparks, non-shielding, with a ceramic pulse sensor (Hall) and equipped with vacuum and over-center ignition advance regulators.

Fig.29. Ignition system ignition box VAZ-2110

A - device; b – diagram of the sub-center regulator; 1 – coupling; 2 – body; 3 – vacuum regulator; 4 – vacuum regulator rod; 5, 7 – vacuum regulator caps; 6, 12 – springs; 8 – fitting for charging; 9 – diaphragm; 10 – subcentre regulator; 11 – contactless sensor; 13 - the plate of the central regulator is inserted behind the screen; 14 - roller with a wire plate of the sub-center regulator; 15 - weights; 16 – oil seal; 17 – cap; 18 – rotor; 19 – dry screen; 20 – front roller bearing trim assembly with sensor support plate; 21 - washer for fastening darts; 22 – sensor support plate with bearing.

The VAZ-2110 distributor has two main functions: firstly, it sets the moment of spark-opening of the wheel installation, the number of turns of the rotary shaft and the thrust on the engine, and in another way, it distributes the high-speed impulses to springs ("spark") along the cylinders in consistent order Their robots. For this purpose the rotor (slider) is used, which is applied to the distributor sensor roller.

In order to avoid damage when folded, the slider and the cover of the heat dispenser are installed on the sensor-dispenser only in one position, like the roller. The runner has a 1 kOhm resistor.

Fig.30. Scheme for checking the Hall sensor on a VAZ-2110 car

1 – firebox; 2 - a voltmeter with a scale reading of at least 15 V and an internal reference of at least 100 kOhm; 3 - view of the plug socket of the firebox.

You can verify the usefulness of the Hall sensor by taking a diagram that shows a small one. Wrap the VAZ-2110 distributor roller completely, following the voltmeter readings. The voltage must change sharply from the minimum (no more than 0.4 V) to the maximum (no more than 3 V less than the supply voltage).

If the steel screen with slots fits behind the sensor (indicated by slight snagging or a flabby sound when the roller is wrapped, as well as after frequent disassembly of the distributor), reverse the axial play of the roller (no more than 0.35 mm, adjustable by selecting washers) and placing the screen on the roller.

If necessary, replace the roller at collection. A faulty Hall sensor cannot be repaired (probably due to broken wires between the sensor itself and the block on the housing of the VAZ-2110 ignition system distributor).

You can roughly evaluate the serviceability of the vacuum regulator on a car. When the engine is running, a vacuum hose leads to the regulator from the carburetor fitting.

If the hose is now loosened, the engine speed will increase, and when removed, it will decrease again. Discharge can be saved for only a few seconds when you tighten the hose.

Visually, the effectiveness of the vacuum regulator can be overloaded by frequently removing the VAZ-2110 distributor and supplying pressure to the inlet fitting of the regulator.

In this case, the plate with the Hall sensor must rotate 7±1°, and when the release is removed, it must rotate back without jamming. Precise verification and adjustment of the vacuum and sub-center regulators of the forward-firing system is carried out on special stands.

The switch type 3620.3734 or 76.3734 disconnects the lance of the primary winding of the VAZ-2110 firing coil, converting the ceramic pulses of the impulse sensor to the flow in the firing coil.

The switch is checked with an oscilloscope using a special technique, but is not repairable. It is not possible to connect the switch connector when the heating system is turned on - this may cause damage to you (as well as other components of the heating system).

The VAZ-2110 firing coil – type 3122.3705 – is dry, with a closed magnetic circuit, and type 8352.12 – oil-filled, with an open magnetic circuit.

Data for verification: support of the primary winding at 25°C – 0.43±0.04 Ohm (3122.3705) or 0.42±0.05 Ohm (8352.12), secondary winding – 4.08±0.4 kOhm (3122.37) or 5±1 com (8352.12).

The insulation base on the mains is not less than 50 MOhm. VAZ-2110 spark plugs - type A17DVR, or A17DVRM, or A17DVRM1, or their imported analogues (with a modified support of 4-10 kOhm).

High-voltage darts – with separate support 2550±270 Ohm/m. Do not touch high-voltage darts on a running engine - this can lead to electrical injuries.

It is also prohibited to start the engine or allow it to run with a high-voltage lancet (removed by wires or sensor-interchanger cover) - this can lead to burnout of the insulation and failure electronic components VAZ-2110 heating systems

As a result, a short-term check of the ignition system “for spark” is possible, in which the contact of the high-voltage rod that is being checked must be securely fastened to a distance of 5-10 mm from the “mass” of the car. It is not possible to handle the wire with your hands or tools (with insulated handles).

Fig.31. Diagram of the system for controlling the electromagnetic valve of the VAZ-2110 carburetor

1 – vimikach zalyuvannya; 2 – cauldron; 3 - keruvannya block EPХХ VAZ-2110; 4 – solenoid valve; 5 - terminal vimikach of the carburetor; A - do dzherel zhizvennya.

The VAZ-2110 Primus Idling Economizer Control Unit (EPXX) turns on the solenoid valve when the frequency of rotation of the crankshaft increases to 2100 xv-1 and turns on when it decreases to 1900 xv-1, as Tseviy vimikach carburetor short circuit to the mass (gas pedal is released)

When the gas pedal is pressed (the valve is open), the switching valve is independent of the rotation frequency of the crankshaft.

Life is supplied to the EPHH control unit only when the ignition is turned on, and when the ignition is switched on, the valve is immediately turned off (regardless of the position of the carburetor end valve). To check the robot, a voltmeter is connected to the EPXX VAZ-2110 heating unit.

There is a line from the end valve of the carburetor and it is connected to the ground. We start the engine and gradually increase the rotation frequency of the crankshaft, following the readings of the voltmeter.

After starting the engine, the voltage should show no less than 10 (the valve is closed), and when the rotation frequency of the crankshaft is close to 2100 xv-1, the voltage should sharply drop to a value of no more than 0.5 (the valve should close).

After this, the engine speed is completely reduced, with a rotation frequency of the crankshaft around 1900 hv-1, the voltage must increase to a large value (the valve must open up).

We install a wrap around 2200-2300 xv-1 (the valve is closed) and it is connected to the “mass” of the carburetor end valve - the valve must open.

Connection to the keruvannya block EPХХ VAZ-2110

We turn on the “minus” line from the battery.

We unscrew the two self-tapping screws securing the right flap facing the substructure tunnel and remove the shield.

We connect the caravan unit EPХХ VAZ-2110.

We unscrew the two nuts securing the block to the bracket and remove the block.

So, having removed the left flap facing the tunnel, the switch of the ignition system comes out of the bracket.

Cleaning the cat's steaming VAZ-2110

The work is carried out with the help of fire.

The central wire is connected.

We unscrew the two nuts securing the darts to the VAZ-2110 firebox and remove the darts.

We unscrew the two nuts securing the coil to the bracket and remove them.

Replacement of the VAZ-2110 ignition distributor

To replace the cover of the ignition distributor (distributor) and the rotor (runner), dismantling the ignition distributor is not necessary. We remove high-voltage darts from the caps.

We unscrew the two screws securing the cover and remove them.

The cover is installed in only one position, and the hole of the first cylinder is marked with the number “1”.

Other wires are installed consistently in the order of operation of the cylinders - 1-3-4-2 (directly wrapping the slider - opposite the year arrow, extending from the side of the socket cover). After pulling, we remove the slider.

Installation of the slider is carried out only in one position if there is a slot on the straightening shaft on the side opposite the contact.

To dismantle the VAZ-2110 distributor, the assembly includes high-voltage rods, a hose from the vacuum regulator and an electrical connector.

We unscrew the nut of the upper fastening of the ignition distributor and remove the high-voltage wire trim.

Having tightened two more nuts, we remove the spacer.

The VAZ-2110 ignition system distributor is reinforced with a humic ring, which can be removed with a tight screw. We can remove the dry screen.

We unscrew the two screws securing the front bearing trim and the screw securing the socket. We understand that it is rose.

We remove the lock washer of the vacuum regulator rod and unscrew the two screws of its fastening.

The vacuum regulator is removed. It is known that the front bearing is connected to the Hall sensor.

We unscrew two screws and remove the VAZ-2110 Hall sensor.

After tightening the screw, we remove the spring. A pin with a diameter of 2.5 mm can be knocked out.

We remove the coupling and adjusting washers, which are responsible for ensuring the axial free travel of the roller is no more than 0.35 mm.

We can install the VAZ-2110 over-center regulator.

The oil seal is knocked out through two openings in the housing.

The new oil seal is pressed into place using a pipe cut.

Place a washer on the oil seal and seal it in several places.

We remove the spacer from the gate sequence by oiling the edge of the oil seal and the bearings.

Before installing the distributor for the VAZ-2110, we tighten the slider, but do not close the cover (or remove the cover when installing a new distributor).

We coat the gum ring with engine oil, push the distributor onto the studs and, turning the shaft by the slider, achieve a connection between the slot of the distributor shaft and the coupling.

In this position, the VAZ-2110 distributor is pressed until it stops and the nuts are tightened.

For easy regulation of the ignition moment, there are “+” and “-” signs on the flange of the ignition distributor, and on the body of the auxiliary units there is an adjustment lug.

One groove on the flange corresponds to eight degrees of rotation of the crankshaft. There is a protrusion on the body of additional units from the middle of the scale on the VAZ-2110 fire distributor. We tighten the nuts.

Behind the strobe, we check and set the moment of ignition. For this we connect the “+” strobe light to the “+” terminal of the battery, the “mass” to the “-” terminal of the battery, and the strobe sensor is pressed to the high voltage level of the 1st cylinder. -

We start the engine and direct the fleeting flow of strobe light into the crankcase hatch. If the timing of the settings is correct, then when the engine is idling when the engine is warm, the mark on the flywheel will be opposite the cut of the crankcase shield.

To regulate the ignition moment, we turn the VAZ-2110 engine, loosen the nuts securing the ignition distributor and turn it to the required position.

To increase the intensity of the ignition, the housing of the igniter is rotated behind the ignition arrow, and to change it against the ignition arrow (as it is visible from the side of the ignition socket cover). Tighten the fastening nuts.

Today we will look at the devices and diagrams of ignition systems on VAZ cars of all main models. The fragments of the carburetor version of the VAZ are already a practical story, which is reported on the fuel injection systems of injection cars. The basis of the ignition system is the electronic ignition module. It is also recommended to carefully select spark plugs and high-voltage wires, and they themselves will contain the spark and, apparently, the ignition system as a whole. The information is intended as a guide for self-repairing a car.

How to check the cat's fire in a VAZ

If the coil malfunctions, the engine will not start. A characteristic sign of a faulty boiler is an increase in temperature when it is heated. This is easy to put on a dot with your hand.

Signs of a faulty firing module may include the following:

• failure to start the engine or vidmova under the hour of startup;
• failures during sudden changes in speed;
• visoka vitrata paliva;
• do not work on two cylinders, the engine will be in a hurry;
• variety of dynamics;
• sudden drop in tension;
• decrease in tension and cravings after warming up.

These symptoms may be caused by the module. To detect a malfunction, it is enough to spend a lot of money on diagnosing spark plugs, high-voltage wires and caps. Here we turn off other elements of the ignition system and we will blame it if the ignition module itself is faulty.

Checking the coil and igniting can be done in one of two ways. The simplest one: remove the central wire from the breaker-distributor, bring it to the motor housing and turn it with the starter, which will cause a spark to run through. After this, we check the supply of energy to the surrounding spark plug, for which we twist the working spark plug, bring it to the ground with its contact and try to start the engine. In this case, the spark must go completely out of whack. In all likelihood, the cause will be a malfunction of such an element of the system as the firing coil.

To check the module in another way, we need a multimeter, then follow the step-by-step instructions:

1. We check the vitality and authenticity of the impulses supplied from the ECU. The life is checked between the central pin (15) of the wire block that connects to the module and the engine mass. When the ignition is turned on, the voltage is less than 12 V. In other cases, either the battery is dead or the ECU is not working.
2. We check the pulses from the ECU on the dart well. One tester probe is installed on connector 15, the other on the far right, then on the far left. The assistant cranks the engine with the starter, and in the meantime we record short-term voltage drops with the tester. Since there are no impulses from the ECU, it is the fault itself.
3. We check the supports on the secondary windings of the coils. We place the tester in the vibrating mode and vibrate it on the high-voltage pins of the module cover. Between 1st and 4th pins and 2-3 pins there is 5.4 kOhm. Otherwise, the module requires replacement.
4. The support of the first windings is checked between contacts 15 and the rightmost, then the leftmost pins. Nominal - 0.5 Ohm. Vigilance is not allowed.
5. We check the module for a short circuit. In ohmmeter mode, we install one multimeter probe on the central base and the other on the metal body. It’s not Opir’s fault. If the device fixes any support (except for one or the other), the module can be replaced.

Connection and replacement of VAZ short circuit

The procedure for removing and installing the coil on an old VAZ model:

1. First, connect the central high-voltage wire leading to the distributor.
2. Place all the ingredients from the contacts of the cat. So how can the stench be attached to the additional nuts, for which you need an 8 key.
3. If you don’t know which parts to connect to which socket, then it’s best to immediately remember or identify them, so that later during installation you can connect them correctly.
4. Unscrew the coil body. It is attached to a clamp (clamps), which is pressed to the car body with two nuts.
5. After finishing the work, you can remove the boiler and replace it as needed.

For new type VAZ cars:

1. We dismantle the “minus terminal” from the rechargeable battery.
2. We remove the dry upper cover of the engine. Since the engine volume is 1.5 liters, then this part is missing and this part is skipped.
3. We remove high-voltage darts from the coil.
4. Now, using the additional key number 13, we tighten the two fastening elements.
5. Using a 17 wrench, loosen one bolt securing the coil.
6. Vimamo module.
7. Using a hexagon, we twist the spool out of the way.
8. Folding is carried out in turn order.

With particular respect to the varto turn on the connections, the fragments of high-voltage parts are to be dissolved in the strict order conveyed by the design. If no one is killed, the car will be damaged or the engine may not start.

It’s easy to replace the boiler with a VAZ. As a car owner, you start working in your garage, and since it all turned out so difficult, you need to go to a car service center. With particular respect, we will be careful to select the product, the fragments from which are deposited to the extent that the engine and the combustion system are well-functioning.

Models VAZ 8 and 16 valves

Regardless of the similarity in engine design, the combustion system of the 1.5-liter injection 16-valve engine is upgraded from the 1.6 engine to 16 valves. The 1.6 liter engine had an electronic contactless ignition system with individual coils on a skin spark plug. Therefore, the ignition module was no longer needed. This system is reliable and cheap to operate; if one coil goes out of order, there is no need to change the entire module.

On the 16-valve injection engine VAZ 2112 with a volume of 1.5 liters, the same non-contact ignition system was installed as on the 8-valve engine, but the ignition module was installed differently. Yogo catalog number 2112-3705010. The design of the module has become unchanged - two firing coils (for 1-4 and 2-3 cylinders) plus key commutators in a single block. The spark is supplied to the cylinders in pairs by a path of idle spark. This means that spark is created in two cylinders at the same time - in one on the compression stroke (working spark), in the other on the exhaust stroke (idle spark).
