What ignition module put on the VAZ 2114. How to set ignition on the injector with your own hands. Wiring Wire Connection Scheme to ignition Module

It is an improved model of the ignition coil previously installed in the domestic classics. Checking the performance of the module does not constitute a special complexity.

Do not try to fix the faulty ignition module VAZ 2114, it must be disposed of immediately

Signs of definition of the module malfunction in an eight-glitched injector

On the neutral transmission Engine turnover is not stable, the operation of the engine is uneven.
There is a significant loss of power and a large vibration of the engine.
Fuel flammable not in all cylinders.
With a sharp acceleration, the thrust breaks.
The information board shows the Malfunction Indicator - "Cheshk Engine".

To identify the cause of the malfunction, in the following ways:

Visiting the station maintenance car.
With the help of self-use of specialized software for car diagnostics.

Possible error codes after diagnostics ignition module VA3 2114 :

If the RH000 code is displayed (RF001, RD002, RF003, RD004) - there is no spark in the cylinders.
If the code Р0351 is displayed - a violation of the integrity of the winding of the coil of the first and fourth cylinders.
If the code Р0352 is displayed - disruption of the integrity of the coil of the second and third cylinders.

The resulting error codes do not only indicate the malfunction of the ignition module itself. The probable cause can be candles or faulty high voltage wires.

To determine the cause, it is necessary to start checking on the principle - from "simple to complex". Make sure the performance of the spark plugs and the integrity of high voltage wiring, and then check the module.

Module malfunction methods

You can identify the cause of the fault yourself or at maintenance stations

An effective way remains a trial replacement of the module to a similar, guaranteed working option. The method is fast, reliable and efficient.

It is not subject to repair and restoration.

If the cause of the breakdown was the ignition module, it is necessary to purchase a good module, and spent - dispose of.

Options for checking the ignition module in the absence of a working module for trial replacement. To determine the cause of the malfunction of the module, you will need a multitetester and the simplest cartridge with a light bulb and wires.

Method 1

To begin with, the value of the resistance of the secondary winding of the coil is measured. The device switches to the measurement position "OM", the next step is to install the probe to the contact exit of the first and fourth cylinders, then the second and third. The device must show the same values \u200b\u200bfor both windings. When displaying one of the windings, more than 100 ohms take damage to the secondary winding, then the module is faulty.

Method 2.

Before installing, do not forget to disconnect the high voltage wires.

Check on the integrity of the wiring connected to the ignition module. Before checking, we switch the tester to the wave measurement position and disconnect the plug with the wires from the module. One of the device's probes is touched into the engine body, and the second is made on the contact "A". Using this method of checking, you will need an assistant that, according to your signal, turn the key in the ignition lock and "twist" starter. The indication for both contacts must match the voltage in 12V.

In the absence of any indication of the device, it is necessary to check the integrity of all three fuses in the chain electronic block Management (ECU).

Access to the fuse block is carried out by the front passenger seat using a figure pumping. The desired fuse of the ignition module for 7.5 amps is located at the top of the block. Of the three fuses, he is at the very bottom. After making sure the integrity of the element, it is necessary to check the condition of all chain contacts and the integrity of the wiring.

Method 3.

Not always at the motorist at hand there is a multi-seater. In this case, the national way of checking the "light bulb" will help. By connecting one of the wires with the contact "A", and the other also on the engine body, screw the starter. The light is cyclically to light up and shine. The same procedure is carried out with the contact "b".

On which analogs can be replaced vAZ 2114 ignition module and their cost

Do not allow high voltage wire confuses, it may damage the coils

On the car VAZ 2114 you can set the module 43.3705 from some domestic cars Teng family, Oka, Izh Oda, having an eight-flaped engine with a block (ECU) M7.9.7. Similar modules 2111-3705010-03 SoTE and 4601.3705 MZATE.

The price for the ignition module varies within from 600 to 900 rubles.

Procedure for replacing and installing ignition module

The procedure for removing the module must be carried out when the minus terminal of the battery is disconnected.
It is necessary to disconnect the high voltage wires from the ignition candles.
Having reserved the latch of the retainer, slide the block connecting the wiring with the module.
Remove with high voltage wire ignition module.
The key to 13 must be unscrewed and remove the two screws of the mount to the Carter.
Using the key on 17 weakened the third screw.
Remove the module with a bracket from the standard location.
Screw the screws "Hexagon" from attachment bracket.

The new module is installed in the reverse order. When installing it is important to connect the high voltage wires to each of the cylinders. On the housing of the module and on the high voltage wires, there is marking for an error-free connection.

Absolutely all information about the ignition module VAZ 2114

To ignition fuel-air mixture in engines internal combustion Both carburetor and injector motors, a high-voltage VAZ ignition coil is required. The emergence of fundamentally new engine power systems, led to changes in the ignition systems. I went to the past ignition distributors, or as they were also called "Persons". Instead, new devices appeared, such as the VAZ 2114 ignition module.

The principle of operation of modules

The VAZ ignition module is an advanced motor start system. The principle of its work is not very different from ordinary systems. If in the old systems, the high-voltage voltage was generated by opening the contacts in the ignition distributor, then in the module, the pulse generator serves signals from the control unit.

The control unit collects signals from the sensors on the engine, generates a control pulse and sends it to the VAZ 2115 ignition module. In it from the voltage on-board network The high-voltage voltage is formed and is sent to the cylinder candle to ignite the fuel and air mixture.

Device module

Device (scheme)

The device includes two coils, the main task of which is the production of high voltage. Helps them in this two-channel electronic switch. All these parts are enclosed, for the manufacture of which durable plastic is used. The housing has a low-voltage connector for connecting the supply voltage and feed control pulses. There are also conclusions for connecting high-voltage wires that are connected to the candles.

The figure shows the electrical scheme of the VAZ 2114 start system. As can be seen from the drawing, it consists of:

Rechargeable battery;
Ignition switch;
Relay, including ignition;
Hall Sensor;
Semiconductor receiver signals from the sensor;
Electronic switch;
Ignition module.
High voltage conclusions.

Also on electrical scheme The fuses of the electronic block power circuits are shown. Let's try to consider the device and the principle of operation of the ignition coil. As already noted, there are two in the block, on the device they are identical. The scheme of the ignition coil of one and the second is also absolutely the same. The principle of operation of the ignition coil remained the same. Both are made up of cores, from electrical steel. They are wound on two windings. One of them is low-voltage, and the second produces a high-voltage voltage to ignite the working mixture.

The Ignition Coil Connection Scheme is made in such a way that the low-voltage winding is connected to the power voltage, and the second end of these windings is connected to the transistor generator. Each coil works "its" transistor. High-voltage conclusions are connected directly to the candles, each winding supplies two candles. One of them gives the impulses to 1 and 4 cylinder, and the second is 2 and 3.

The location of the wires on the ignition module is located in this way. Contacts A and B receive control pulses from an electronic switch, the output of D is powered by the machine onboard network. The output denoted by the letter C is connected to the mass of the car.

Where to look for this module

Weakly believe that the driver who is taken for checking or repairing this instrument does not know where it is located. Well, for those who do not know - tell me. It is easy to find it, drop at least one high voltage wire, and go through your hand on it from the candle to the plastic case, which belongs to the module.

From the picture, its location becomes more clear.

There are such signs of faults.

On the question of what signs of the ignition module of the VAZ 2114, any driver without thinking, will say that there is no spark on the candlelight. Partially it is so, but there are some more possible causes failure of this device. You can observe such:

The dynamics disappeared during accelerations, there were failures in the operation of the motor with a sharp press on the gas pedal for a speed set;
It became noticeable to reduce the power of the engine, the drivers speak in such cases, the motor does not "pull";
Idling strongly floats;
There is no spark on one of the pairs of candles.

When signs of malfunction of the ignition coil appear, then checking must be started with candles that do not work, then the sensor indicating the position crankshaftThe latter is subject to checking the module.

How to check the system for performance

Check in any case start with candles. To do this, they need to withdraw from their nests. This is also easy to do. The tips of high-voltage wires are removed from them and with the key to turn the candles, remove them from their places.

Next, their inspection, cleaning and checking. They must have a working brown, in the absence of soot and nagar. If their presence is observed, then wear pistons and rings can exist. In any case, the candles are cleaned, check and, if necessary, exhibit a gap between the electrodes. After that, you can check their performance.

For these purposes there are special probes. "Cleells" manage to produce such products on their own from piezoshigali. If nothing like this is available, then check on the engine. Well, if there is a car with a well-serviceable starting system nearby. It will give the opportunity to put an accurate diagnosis for candles. If they are good, the search continues on.

Many publications recommend checking the presence of high voltage voltage at the instrument outputs. Make it in the conditions of the garage problematic due to the lack of a special measuring instrument. The usual tester is applied here, as it cannot measure several tens of high voltage kilovolts. If there is a radio amateur experience, you can collect a voltage divider.

Check the presence of high voltage is dangerous due to a possible sensitive shock, therefore we will tackle other methods. Let's talk about how to determine the problems of the ignition coil and check this system:

The simplest method will be replaced the block in a serviceable device. It is not always possible, since not all drivers take with them this device about the reserve;
It is also advised that it has been checked repeatedly, to move the device or knock on it during the operation of the motor. If change is noticeable, they indicate poor contact inside the instrument. Sometimes it is corrected;
Check by a tester or multimeter in resistance measurement mode. The resistance of paired conclusions of coils, 1 and 4, as well as 2 and 3. It must be identical for both windings and is approximately 5.4 kΩ.

Prevention system

With all high reliability electronic devices, breakdowns still happen. Sometimes they can be avoided if they carry out even sometimes inspection and maintenance of the elements of this system:

Do not allow confusion with high voltage wires if their internal resistance increases greatly, it may damage coils;
Check the gap between the electrodes of candles, as too large spark gap is also negatively reflected on the instrument.

On the possibilities of repairing the module

Most of the breakdowns of this device lead to its replacement, but sometimes it is possible to repair the ignition coil to return it. This applies to those cases when the movement or climbing change the behavior of the motor. If there is a skill to handle a soldering iron and a multimeter, you can try to return it to the system.

It is necessary to remove the metal back cover, under which the electrical parts of the module are filled. It is necessary to try to carefully get rid of silicone and your "inside" will open to your gaze. Lay the tormented or "bad" contacts and read them.

Conductors in the aluminum block, so for their soldering you need a special solder.

After that, cover the back cover and check its performance. With a positive result of repair, it is necessary to open it again and fill the inside of silicone.

If the result is negative, the block must be replaced. True, the owners who have great amateur experience continue to "dig" further. You can try to replace electronic switches. Basically, these two elements become perpetrators of the failover of a motor start system.

We change the module of the ignition system

When the repair of the ignition module did not give positive results, it remains to search and install a new device. Most mechanics are recommended to stay on the instrument "GM", as a very reliable product. Its value in different regions is changing, but close to 2000 rubles. Replacing the ignition module can be performed independently, the features are not observed, special devices are not needed. Prepare for work:

Ignition block for replacement;
Key on "13";
Rag.

Work can be easily performed in the garage or on a flat site. Procedure for conducting work:

Open the hood motor compartment And disconnect the terminals rechargeable battery. It is enough to remove the terminal only with the "minus".
After that, take out high-voltage wires from your installation places. You need to remember where which wire stood. If you doubt your abilities, make tags. Change wires can not be changed. You can delay a new spare part.
On the next Stage Gently disconnect the connector with the wires from the module. In the course there is a key to "13", which are unscrewed by three nuts fastening the device to the motor.
When the nuts are removed, the device is removed from the engine.

Now let the vehicle, which wipe the installation place and around it. Carefully inspect the new device and start it. It is carried out in reverse sequence to removal. Once again I want to remind you about the importance of installing high-voltage wires into place. If all the same difficulties arose, then take a look at the block. It shows the numbers of high-voltage wires.

The rooms are the order of the wires of the wires in the module

It should be noted that on sale you can still find the ignition modules of the old sample, on which there is no designation at the high-voltage conclusions of the wire numbers. If such a device is purchased, be careful when installing it.

Ignition Module VAZ 2114: Basic Signs of Malfunction

Design
Signs of breakdown
Check
Repair or replacement?
Installation

In our today's material, we will talk about how the ignition module is checked on the VAZ 2114, how it works and why there is so much in the car from its functional state.

Ignition module

Design

The ignition module is quite difficult, since it combines the technique and an electrician. The device is used to create a high voltage transmitted to the spark plug. It is this supplied current that is the basis for the ignition.

The operation of the module provides combustion of fuel and, accordingly, the operation of the engine. Speaking quite ordinary language, without a module, the car will not go anywhere.

For VAZ models, the use of two types of ignition modules is envisaged:

Blocks are distinguished by the fact that the coils work on one on a pair of spark plugs. Such devices are installed on the "fourteenth" model of the domestic automaker.

The coil distributes the claim to two candles at once, and its design includes the following elements:

High voltage wires;
Low voltage terminals;
Secondary and initial winding;
Core.

Separate modules where coils are fed to each of the 4 sections a separate suit, differ in the output of high-voltage wires through the contact of the spring. Block is easier to check, they are easy to remove and return to the place.

It is noteworthy that with the amount of 11x11x7 centimeters, this unit weighs about 1.5 kilograms.

Signs of breakdown

In disassembled form

In fact, signs of malfunction at the VAZ 2114 ignition module are largely similar to breakage of other aggregates. For example, you can observe the following phenomena:

Troit engine;
The car stalls on idling;
There are problems when trying to start the car, etc.

That is, in fact it may not be the module at all. Therefore, the only correct solution is to check the ignition module on your VAZ 2114.

Check

This is explained by the fact that damaged or defective wires direct the wrong current, the configuration of which does not match the necessary parameters. From this spark comes inaccurately or inefficiently, the module burns out and comes in disrepair.

At all the best way Checking the ignition module on the VAZ 2114 is the use of oscilloscope. But, first, it is not far from every driver, and secondly, few people can use them. Therefore, the inspection will be carried out with the help of submitted means:

12-volt light bulb;
Tester (available for little money in any auto parts store).

Let's start with preliminary manipulations with the accompanying elements of the ignition module.

Check the wire block. It is disconnected and the voltage indicator is checked.
To do this, fix the tester on contact A, and throw another terminal to the mass of the engine.
In normal condition, the voltage indicator will be 12V.
If the tension is most likely, the fuse burned down.
If all is well, throw the terminals of your tester to A and in contacts, get the car. In this case, the starter should twist, and the 12-volt light bulb flashes.
In the absence of data phenomena, you can talk about the presence of a break in the chain and contacts.

There are several ways to check the status of your aggregate. Therefore, consider each of them.

Stop the tester to the Ommeter mode. To measure them resistance on high-voltakers passing on cylinders 1 and 4, and then by analogy to wiring 2 and 3 cylinders. In the normal state, the device will give you indicators from 5.2 to 5.5 ohms.
Serve a slightly device. Thus, you will shid the wire block, the module. And it is necessary to do this in the mode of a working power unit. If, when looming the device works without obstacles, everything is fine, you are lucky. If not, again it is necessary to study the condition of the wiring.

Third way

The third method is considered the simplest because it provides for the replacement of your device to a similar one that works exactly. But for this you have to find a full twin. We are talking about the ignition module from a car similar to your year of release and used power aggregate. Just on 1.5 liter engines are modules, and on 1.6-liter motors - coils.

But to replace the module to the module, you will have to first disassemble your. This is done as follows:

Remove the minus terminal from the battery, which will allow making a car;
Disconnect four high-voltage from the ignition module;
Disconnect the wire block. To do this, squeeze a special retainer holding a block on the module;
Next, the three nuts are unscrewed. With their help, the module is held on the bracket;
On the bracket there are three long studs, from which the module will just pull.

By dismantling your module, you can put another unit in its place, thereby make sure the performance of your malfunction.

Repair or replacement?

As the practice and experience of car repair masters shows, most often repaired this device does not seem possible. The module is only subject to replacement. If you go on the principle, you can perform repairs, but it will take a lot of time, forces and even money.

Installing a module

The optimal option is to purchase a new device. It is in the area of \u200b\u200b2-4 thousand rubles. It all depends on the manufacturer and state. You can buy a perfect new one, although many are preferred used to devices. There is already a choice for you.

Installation

A module is installed strictly in the reverse order of dismantling. It is important to consider the three rules.

After installing the module, look at the surface of the device. It shows numbers from 1 to 4. These are the designations of cylinder numbers.
At the ends of high-voltakers there are similar numbers - from 1 to 4. They serve as a guide to determine which high-voltage to which jack on the module is connected.
No experiments. Everything connects strictly in accordance with the marks - 1 to 1, 2 to 2 and so on.

In fact, replacing the ignition module on the VAZ 2114 is quite easy to implement. For this you do not need to be a professional car mechanic. Just follow the basic rules for dismantling and installing, check the device before spending money and change it to a new one. It's not a fact that the culprit of problems with your car will be the module to which you sin.

This table will allow you to check whether the wires from the ignition module to the cylinders are correctly connected.

How to check the Ignition module VAZ-2114 Injector 8 valves: Photo

For independent diagnostics Engine, its systems and characteristics, use minimum equipment. For example, before checking the ignition module of the 8th VAZ-2114 valve vehicle, it is desirable to have a special stand needed software Or in extreme cases - the oscilloscope. There is no such equipment such equipment and there will be no such equipment, therefore, for preliminary checks, we will use sweater tools and devices.

How to check the Ignition module VAZ-2114

Interruptions and jerks when moving, a running engine, difficult to start or generally refusing the engine is the main signs of the failure of the ignition module.

Ignition module

The complexity of the diagnosis on its own is that several devices are aligned in the module, and it is performed in a single case and check each device separately - there is no possibility. At least with bare hands. Nevertheless, something can be done in order to, if not repaired, then at least for sure to know about the cause of the fault.

Check the quality of contacts

First of all, without dismantling anything, it is worth checking the quality of the contact on all chain pads low voltageand also set the presence of contact on high voltage wires.

Verification of power availability on the ignition module

Checking voltages on the ignition module pads

In order to know that the module is faulty, check if the power is fed. To do this, we find a connector in the block, and there we are looking for a contact marked by Litera A. To control the power of the module, we take a multimeter, set it into the measurement mode of the AC to 20 V, set one probe (minus) to the motor weight and turn on the ignition. The second probe is set to the output and on the block. With a good electrical equipment, the multimeter will show 12 V, it means that the power supply to the module is supplied, we are looking for the cause of the fault further.

We check the contacts of the connector

We have already conducted a preliminary check and made sure that the nutrition on the ignition module is supplied. Now it is worth dealing with the contacts separately. When the ignition is turned on, you need to connect the control lamp to the contact A and contact V.

The control may be a conventional low-power 12-volt lamp with soldered wires, and you can use a tester car dipper with a voltage indicator by 12 V.

Checking the ignition module

To check the performance of the module, secure contacts from the control lamp or the probe on the conclusions A and B, then scroll the engine starter.

If the lamp becomes blink, the module gives a tension to a voltage by analogy with the contact breaker.

In this case, with contacts A and in everything in order.

If the lamp does not respond to starter start, the module is unambiguously faulty.

Checking the module 2114 available in ways

Most effective method Find out that the ignition module does not work, take a worker working device and try to start the engine on it. It is clear that not every module from the eights, nine and the second generation can come up.

Depending on the type of ignition system, the coil can be installed on Samara instead of the module, and we need the module from the injection 8-valve 2114. Here everything is simple - the engine earned, it means that the module has been removed, change to a new one. Nevertheless, there is a high probability that high-voltage wires are punched and it will spoil not only the entire picture of the diagnosis, but also someone else's ignition module.

Check the integrity of high-voltage wires

Therefore, before checking the module directly, you must make sure that the high-voltage wires are in order, do not break into the mass and skip the current.

The actions algorithm for subsequent verification is:

conclusions

As anything, an affordable device, the ignition module is most often replaced. So you can save a bunch of time and nerves that are not worth the money that is asked for a new module. Successful to all work!

Ignition module VAZ-2114: features and characteristics

Each of us knows that to ignite the fuel and air mixture in the combustion chamber requires a spark. The latter is formed just due to the operation of the ignition system. Her design is different cars It has some differences, but its main principle of work remains unchanged. And today we will talk about how to check the VAZ-2114 ignition module, as well as how to replace it with your own hands.

Characteristic

This element of the car is a complex electrical device, the main purpose of which is to generate a current of high voltage and transmitting it to the candle. A total of two types of modules are used on cars - with one coil for each candle (separate) or immediately for two (block). Ignition module VAZ (2114th "Lada") - block type. Such elements include in their composition a double coil. The design of this part involves the presence of the following components:

Low voltage terminals.
High voltage output.
Iron lamellar core.
Primary and secondary winding.

The same analogues have a slightly different design that includes:

Core.
High voltage connections through spring contact.
Candle.
External terminal for low voltage.
Secondary and primary winding.

Unlike the one-bar, such coils are easier to assemble due to their special (block) design, which has a common case. Despite the fact that there are several such elements in the block, they all work as independent devices. This design makes it possible to apply a shortened conductor, which goes to the primary winding of the mechanism.

Ignition module VAZ-2114 - malfunction

On the wrong operation of this system can be judged by the following features. First, the faults can speak the coil when setting the velocity of the car. Secondly, it can manifest itself in a significant loss of car power, as well as in "floating" idling Engine. And thirdly, the irregular operation signals the non-working 1-4 or 2-3 cylinders.

It should be noted that such symptoms are very often happening because of the faulty DMRV, or the idle regulator. Therefore, first of all, we look at their performance, and only then diagnose the ignition module.

VAZ-2114: Where is this detail?

On the cars of the Lada Samara-2 family, this element is placed in open space.
The easiest way to detect it is to find high-voltage wires. One end of their end reaches to the candles, and the second goes to the ignition module itself.

How to propagate the operation of the module?

Checking the ignition module (VAZ-2114 "Samara-2") for performance is performed in such a sequence. For a start, we take out the negative terminal of the battery, after which it takes the electrical wiring from the coil mechanism. Next, unscrew all the screws and bolts that fasten the element housing. Further all works (as before) are made when the engine is turned off. We disconnect the assembly of the module, using the multimeter measure between the terminals of the contact connector, the level of general resistance. Then compare the results with the table standards that are listed in the instruction manual. If the obtained data differ significantly from tables in a smaller side, it means that a short circuit of the chain occurred in the machine, and the coil came into a malfunction.

After installing the wirelessness of the wires, you can proceed to the diagnosis of the secondary circuit of the DVS - measurement of the resistance level between the ignition terminals. According to measurements, we draw conclusions, and if the malfunction was hidden in the coil, it means that the module must be completely replaced. There are no other options for solving this problem.

How to replace the device with your own hands? Instruments

To begin with, we need to prepare a set of keys we will use. During the execution of work on the removal and installation of the ignition module, we will need two end keys by 13 and 17 millimeters, as well as one roof key on "10". We will need the latter in order to remove the terminal from the battery. In addition, a hexagon should be prepared on "5". With the help of the latter, we will release the ignition module from the holder when dismantling.

Detail removal process

So, how is the replacement of the ignition module of the VAZ 2114th "Lada"? First you need to de-energize the car network of the car. For this, as in the previous case, we remove the minus terminal with the battery (if it has not yet been removed before). Next, you need to remove the decorative engine overlay. You can do it by twisting the oil bay cover. It is worth noting that this operation is used only by the owners of vases with a 1.6-liter engine. One-liter "Samara" are not supplied with a similar engine overlay.

In the next step, remove the block with wires and high-voltage wires from the module. Using the key to 13, you unscrew the two engine crankcase fastening bolts, the horn to 17 unscrew the last mount of the module. Then this detail is quietly extracted from the workpiece outside. The module itself is released from the holder using a hexagon of 5 millimeters.

Installation

Before installing new element In the car, you should connect high-voltage wires in advance according to the module scheme. It is also necessary to pay attention to the quality of fasteners - extra oxidation and dirt are thoroughly cleaned at the ends in the places of compounds.
Further, the ignition module of the VAZ 2114th "Lada" can be safely installed on a regular place. An element assembly is made in reverse order. After the ignition module is connected, the VAZ-2114 must be started and checking the performance of parts. If all of the above fault symptoms disappeared, then you did everything correctly.

Conclusion

So, we found out what the ignition module is and how to replace it. Finally, we note that when connected, it is important to monitor the correct connection of the entire wiring circuit, since with the slightest error it will not be possible to ensure the efficiency of the details of this system.

Ignition module VAZ, repair and replacement with your own hands. Replacing the Ignition Module VAZ 2114. Independent Replacing the Ignition Module VAZ 2114

To call the fuel-air mixture, and in injection, and in the carburetor motors of internal combustion, a high-voltage ignition coil is required. The emergence of new motor power systems in the market caused changes in the Ignition systems of the VAZ. The ignition distributors, referred to, gradually go into the past. To replace them, new devices come - VAZ 2114 ignition modules.

Module VAZ2114, device and principle

The VAZ Ignition Module is an advanced engine starting system. Its principle of operation is actually not different from standard systems. If high-voltage voltage in outdated systems was generated by disconnecting of contacts in the ignition system distributor, then the pulse generator in the module are signals supplied by the control unit.

Signals from sensors from sensors are collected on the motor and the control pulse is generated, which is sent to the ignition module. From the voltage of the on-board network, it forms high-voltage voltage and directs to the cylinder candle to ignite the air-fuel mixture.

The composition of this device includes two coils that produce high voltage. A two-channel electronic switch helps them. All elements consist in a housing of durable plastic. The housing is located low-voltage connector for feeding control pulses and connecting the supply voltage. In addition, there are conclusions here to connect high-voltage wires, which are connected to the candles.

VAZ2114 ignition module, fault signs

You can meet such signs of the vehicle ignition module of the VAZ 2114 model:

On one of the candles there is no spark.
Strongly floats idle.
Motor power decreased significantly.
Drying disappeared, during a sharp pressing of gas pedal in the engine, there were failures.

Ignition module, can the module repair is possible

In fact, all breakdowns of this device lead to its replacement, but in some cases it is still possible to repair the ignition module. This is especially possible when changing the engine behavior during tapping or movement. You can repair the module yourself, if you can handle a multimeter and a soldering iron.

You need to remove the rear metal cover under which are located electrical elements ignition module. Gently get rid of silicone, find damaged or trim contacts and read them. Do not forget that in the block aluminum conductors, so the necessary special solder for their soldering.

After that, the back cover is closed and check the performance of the module. If the result is positive, open the lid again and fill the inside with silicone. With a negative result, replace the module. Although you can still try to replace electronic switches.

Checking system for performance

In any case, the check must be started with the candles, for which we carry them out of the nests. It is very simple to do it. It should be removed from them the tips of armored wires and withdraw from seating With a special key for turning.

Then you need to examine them, clean and check. They should have brown, without soot and nagar. If the nagar is, it is quite possible that the pistons and rings were worn out. In any case, candles should be cleaned, check and, if necessary, set a gap between the electrodes. Now check their performance. Special probes exist to check them. Some drivers are capable of making it with piezoshigali. If there is nothing like that, then check on the motor. With the health of the candles, you need to continue the search further.

Tools assistants

Replace the ignition module independently every driver can not need special equipment or special skills. All that will be required to motorist:

Rag.
Key to 13.
New ignition unit.

Ignition module 2114, replacing the module with your own hands, step by step instructions

Such works can be performed on a flat site or in the garage.

First you need to open the hood of the motor compartment and disconnect the terminals of the battery. It will be enough to remove only a minority terminal.
Next from the installation places, take out high-voltage wires. It is important to remember their location. If you have doubts you can make tags. You can not change the wires in some places, since the new replacement part May fail.
Then you need to carefully disconnect the connector with cables from the module. We take the key to 13 and unscrew the three nuts fastening the device to the engine.
After removing the nuts, the device is removed from the motor.

Now we take the rag and wipe the installation site and near it.

The new device should be carefully examined, after which it is necessary to start the installation that must be carried out in the reverse order.

Do not forget to install high-voltage wires correctly. If you are still confused, pay attention to the block on which the number of armored wires is indicated.

Even though electronic devices Pretty reliable, breakdowns are still. In some cases, they can be avoided, for which it is necessary to increase and maintain all the parts of the system sometimes:

Watch that there is no confusion with high voltage cables - with a large internal resistance in them, can fail the coil.
Between the electrodes of candles it is necessary to check the gap, because overly large spark gaps are negatively reflected on the device.

How to remove and change the ignition module on the VAZ-2114: photo and video

The ignition module accepts the control pulse from the control unit and transmits it to the cylinder candle to ignite the air-fuel mixture. The device itself consists of two coils that produce high voltage, and a two-channel switcher. The body of the product is made of durable plastic.

Frame of ignition module

Violations in this element can be manifested as follows:

Noticeable reduction in motor power.
Lack of spark on one of the candles.
Noticeable "swimming" idling.

These features show that malfunctions have arisen in the operation of the ignition module. If they manifested themselves, it is worth replacing the ignition module.

Replacing the ignition module on VAZ-2114

Packing from under the original part

To replace the ignition module, you will need a rag and key to 13. It is best to do on some flat site.

Progress

Checking the ignition module (video)

What if after replacing the module malfunction remained?

In the first place it is necessary to check the operation of the new module.

Checking the ignition module

Resistance between contacts: 1 and 4, 2 and 3 - should not be higher than 5.8 com!

If, after replacing the ignition module, nothing has changed, it means that other elements of the ignition system are faulty.

Candles and ignition system

If it does not help, you need to check the candles and, if necessary, replace (see selection of candles on VAZ-2114).

Inspection of the state of spark plugs

Before that, you need to remove the tips of the armored wires. To unscrew the candles, you will have to use a special key for turning. Then the candles should be viewed: they must have a regular brown and on the surface there should be no car or soot.

If the module's replacement has not corrected the position, and there is a tag on the candlelight. This means that rings or pistons were wear out, they must be replaced, and the candles clean and install back in the connector. It is also worth checking the gap between candles and electrodes - too much distance badly affects the operation of the devices.

Detailed replacement process on video

conclusions

Thus, it is not very difficult to replace the faulty ignition module. It is important not to confuse the location of high-voltage wires, this leads to a rapid output of a new device due to a strong change in internal resistance in the wires. It should be borne in mind that the malfunction is sometimes not related to the breakdown of the ignition module.

In our today's material, we will talk about how the ignition module is checked on the VAZ 2114, how it works and why there is so much in the car from its functional state.

Design

The operation of the module provides combustion of fuel and, accordingly, the operation of the engine. Speaking quite ordinary language, without a module, the car will not go anywhere.

For VAZ models, the use of two types of ignition modules is envisaged:

Separate;
Block.

Blocks are distinguished by the fact that the coils work on one on a pair of spark plugs. Such devices are installed on the "fourteenth" model of the domestic automaker.

The coil distributes the claim to two candles at once, and its design includes the following elements:

High voltage wires;
Low voltage terminals;
Secondary and initial winding;
Core.

It is noteworthy that with the amount of 11x11x7 centimeters, this unit weighs about 1.5 kilograms.

Signs of breakdown

In fact, signs of malfunction at the VAZ 2114 ignition module are largely similar to breakage of other aggregates. For example, you can observe the following phenomena:

Troit engine;
The car stalls at idle;
There are problems when trying to start the car, etc.

That is, in fact it may not be the module at all. Because the only correct decision is checking the ignition module On your VAZ 2114.

Check

In general, the best option to check the ignition module on the VAZ 2114 is application oscilloscope but. But, first, it is not far from every driver, and secondly, few people can use them. Therefore, the inspection will be carried out with the help of submitted means:

12-volt light bulb;
Tester (available for little money in any auto parts store).

Let's start with preliminary manipulations with the accompanying elements of the ignition module.

Check the wire block. It is disconnected and the voltage indicator is checked.
To do this, fix the tester on contact A, and throw another terminal to the mass of the engine.
In normal condition, the voltage indicator will be 12V.
If the tension is most likely, the fuse burned down.
If all is well, throw the terminals of your tester to A and in contacts, get the car. In this case, the starter should twist, and the 12-volt light bulb flashes.
In the absence of data phenomena, you can talk about the presence of a break in the chain and contacts.

There are several ways to check the status of your aggregate. Therefore, consider each of them.

Stop the tester to the Ommeter mode. To measure them resistance on high-voltakers passing on cylinders 1 and 4, and then by analogy to wiring 2 and 3 cylinders. In the normal state, the device will give you indicators from 5.2 to 5.5 ohms.
Serve a slightly device. Thus, you will shid the wire block, the module. And it is necessary to do this in the mode of a working power unit. If, when looming the device works without obstacles, everything is fine, you are lucky. If not, again it is necessary to study the condition of the wiring.

Third way

The third method is considered the simplest because it provides for the replacement of your device to a similar one that works exactly. But for this you have to find a full twin. We are talking about the ignition module from a car similar to your year of release and used by the power unit. Just on 1.5 liter engines are modules, and on 1.6-liter motors - coils.

But to replace the module to the module, you will have to first disassemble your. This is done as follows:

Remove the minus terminal from the battery, which will allow making a car;
Disconnect four high-voltage from the ignition module;
Disconnect the wire block. To do this, squeeze a special retainer holding a block on the module;
Next, the three nuts are unscrewed. With their help, the module is held on the bracket;
On the bracket there are three long studs, from which the module will just pull.

By dismantling your module, you can put another unit in its place, thereby make sure the performance of your malfunction.

Repair or replacement?

As the practice and experience of car repair masters shows, most often repaired this device is not possible. The module is only subject to replacement. If you go on the principle, you can perform repairs, but it will take a lot of time, forces and even money.

Installation

A module is installed strictly in the reverse order of dismantling. It is important to consider the three rules.

After installing the module, look at the surface of the device. It shows numbers from 1 to 4. These are the designations of cylinder numbers.
At the ends of high-voltakers there are similar numbers - from 1 to 4. They serve as a guide to determine which high-voltage to which jack on the module is connected.
No experiments. Everything connects strictly in accordance with the marks - 1 to 1, 2 to 2 and so on.

In fact, replacing the ignition module on the VAZ 2114 is quite easy to implement. For this you do not need to be a professional car mechanic. Just follow the basic rules for dismantling and installing, check the device before spending money and change it to a new one. It's not a fact that the culprit of problems with your car will be the module to which you sin.

This table will allow you to check whether the wires from the ignition module to the cylinders are correctly connected.

The ignition of gasoline in the internal combustion engine cylinders occurs with the help of spark that the ignition system generates. The ignition module is the main element of the system that creates a spark on the candlelight using high voltage. Each manufacturer of cars is developing and produces its original module, but the principle of its work is the same for all devices. During operation, the deviation from the specified parameters or the breakage of the ignition module adversely affects the operation of the engine up to the failure of the power unit.

Appointment and principle of work

Ignition module VAZ 2110

Ignition module modern car Performs a high voltage generation function to form a spark on candles. It consists of two coils with a closed magnetic core and a two-channel switch. Sometimes the switch is made in the form separate deviceBut in most cases it is combined with an electronic engine bu. Externally, the modules differ in the number of wire connector wires: the module with the switch has 4 wires, and paired coils - 3.

The ignition module is controlled by the ECU, which serves at the desired moment on the winding of its coils a constant voltage in the form of low-voltage control signals. The end of the signal is the beginning of the spark. Due to the magnetic induction, at the time of the feed, high voltage is generated, creating a spark on the spark plug. The device is placed in the rotor space, it is easy to determine by high-voltage wires that go to the ignition candles.

Signs of ignition module malfunction

Checking the ignition module on the twisted candle

The ignition module malfunction is determined by the following features:

Difficult launch of a cold engine due to the lack of spark on one or more candlelight.
Floating engine speed at idle - the situation in which the frequency of revolutions changes without any action from the driver.
Dips in power, which is manifested in acceleration and motion on a protracted rise.
Motor power drop.
1-4 or 2-3 cylinder does not work (the engine "Troit").
Indication of the "Check Engine" alarm.

Possible causes of ignition module malfunction

Despite the high reliability and strength of the ignition module, it may fail, similar to any other mechanism. Among all possible causes of breakdowns, in 9 out of 10 cases, the following are diagnosed:

Application in the ignition system inappropriate components. The high-voltage wires are selected, based on the parameters of the module, since excessively high or reduced voltage creates malfunctions or overtakes contacts.
Defective or damaged details, poor-quality assembly. Bracking components break faster and output other nodes or system elements. Practice shows that the selection of high-quality components and their periodic diagnosis allow you to remain a module operational for a long time.

Checking the ignition module

Checking the ignition module for performance is carried out in the following ways:

Replacing the ignition module on knowingly good

1. The easiest way is to connect a deliberately working module. In this case, devices must be completely identical, high-voltage wires are good, and the reliability of contacts is checked.

Checking contacts on the ignition module

2. The movement of the module that allows you to identify unreliable contacts. To do this, move the block of wires, and the module itself. If the engine reacts in the process by changing the operation, then the cause of problems lies in bad contact.

Measurement of resistance on the ignition module outputs

3. Measurement of resistance. To do this, you need a tester switched to an ohmmeter mode. Measurements are carried out on paired conclusions of the module between 1 and 4, as well as 2 and 3 cylindrome. The magnitude of the resistance should be the same, and approach the 5.4 com.

Checking the ignition module with the tester

4. Check voltage tester. One probe applied to the contact and the pads, the second for the mass. After switching on the ignition, remove the instrument readings. With a good wire, it will show the voltage of 12 V, with its absence it is checked by a fuse that protects the ignition module. After checking the integrity of the chain control lamp 12 V. One end of the wire is applied to contact A and rotate the starter. If the lamp does not blink - the chain is converted. The procedure is similarly repeated with other contacts.

Professional Equipment Module Diagnostics

5. Diagnostics at the service station using a computer connection with special software to the ECU. Faults are detected as errors marked by alphanumeric code, after which a deeper malfunction is carried out to make a solution to repair the ignition module, or its replacement. A similar check is carried out on a specialized service station using an oscilloscope.

Repairs

VAZ 2107 ignition module

The device of the ignition module is quite complicated: it includes one or more coils, fees, contacts and wires. All of the above-mentioned repair elements can be repaired only by contact compounds, in some cases it is possible to replace parts (transistors, coils).

The module for the purpose of repair is dismantled and opened. To do this, you will need:

Face keys with heads for 1, 13 and 17.
Hexagon on 5.
Screwdriver.
Soldering iron.
Flux for aluminum.
Strategic wire.
Nail polish.

Opening the ignition module

Repair of the ignition module is performed in the following order:

On the removed device, the housing is opening, going to it with a screwdriver.
Remove the silicone film covering fee.
From the entry of contacts remove all aluminum.
On the board, in return for all the dismantled oldest new wires solder. For this, the surface of the collector is cleaned from the plaque, after the board heated to 180 o C (about the occurrence of the desired temperature will know the characteristic odor). In the process of soldering, the ends of the wires are connected to the module.
At the end of the operation, all contacts, fees and module are nailed for nail polish.
The device is collected in the reverse order, installed on the car and start the engine. When normal work The ignition module is stuck with a sealant tightly, while the wires are refilled inside the cavity so that they are not covered with the plates along the edges.

If the device does not work, then the breakdown inside the module should be seen more carefully. There may be a transistor, an electronic component or a breakdown in the coil. This repair makes sense only if its price is significantly lower than the cost of the new part.

The first machines of this series were produced with a non-contact ignition system, and the electronic appeared only later. Due to the fact that throughout its history, the car was completed in different ways, before setting the ignition on the VAZ 2114, it is necessary to find out what it is.

Ignition systems 8-valve injection VAZ-2114

It is possible to determine the type of ignition by looking under the hood:

If you found the interrupter near the "heart" (analogue of the battlefield installed on contact Systems), So your car refers to the first series, and the ignition of the VAZ 2114 The injector on it is non-contact, based on the camshamber interrupter node. The ignition in such systems is exhibited by partially turning the distributor, and the results of work depend on the experience of the experimer and the presence of special equipment. So, with the help of a stroboscope, the system can be launched exactly as the owner of the car wishes.
If this details are not, then your car belongs to representatives of a tenth family, completed with an electronic ignition system. It is impossible to put this manually, and its work is fully controlled by the ECU. However, it is not fully regulated, because with the help of connecting to on-board computer Part of its parameters can be reconfigured to their taste, but specialists can make it correctly units.

IMPORTANT! The electronic system in the VAZ 2114 is created so that the owner does not have to serve it, so if you do not plan to participate in racing competitions in your car, it is better not to climb the software.

Causes of Ignition Problems

As mentioned earlier, to set the ignition in the electronic system will have to climb into the "brains", there you can check the performance of the sensors, so they strongly affect the operation of the system, regardless of the type of ignition.

On electronic type, the main causes of failures are:

Incorrect information transmitted from sensors to the ECU. If the connection to the brain and diagnostics showed strange data from one or several control devices, it is necessary to use "Replacing". The easiest way is to find a car with obviously good sensors, install them and double-check the result. You need to understand what you need not new, namely the working sensor, because the factory marriage is not excluded even on the new mechanism.
Incoming voltage - it is correct from a technical point of view, it is 5V, but if due to the violation of the mechanical integrity of the wires or other problems with the electronics of the car, this voltage changes, and the sensor readings will change after it. If this happens, the ECU begins to adjust the operation of the engine, based on incorrect data, which leads to the incorrect work of the entire mechanism as a whole. To verify this breakdown, you will need a deliberately serviceable system of wires leading to the sensor or the donor machine into which you can install your sensor and check the system for performance.
Broken ECU - In the event that previous two options did not give a visible result, and the installation of your sensor and wiring in a good machine does not change its performance only this option remains. You can try to reflash the brain of the car, but in view of its low cost, it is better to immediately buy a new computer and install it on the car.

Before moving to radical measures proposed in the third version, it is worth further to check the correctness of the location of the labels. In the machines S. contactless ignition This is the installation of the VAZ 2114 ignition, and for a car with an electronic system debugging is important as an inspection of the injection system synchronization with a gas distribution mechanism.

We prepare for ignition adjustment

To properly put the ignition advance of the VAZ 2114 and debug must be prepared. The method described below will not require the owner of acrobatic across and fulfill both in the uncomfortable and close setting of the garage and in the presence of a motorist of the tummy.

IMPORTANT! Great preparation always accelerates the process technical work, regardless of what exactly needs to be repaired.

Preparation for debugging ignition marks is as follows:

The car is installed on a flat surface and put on the handbrake.
The second stage must be removed the front right wheel, which will subsequently allow access to the gas distribution mechanism itself, which will speed up the work, make it comfortable and easy, for this:
but. We unscrew the fasteners of our wheel and put the anti-taking shoe under the diagonally opposite wheel (rear left);
b. We raise the car to the jack, twist the fastenings of the wheels completely and remove it.
In conclusion, we need to remove the timer belt mudguard (if it is, of course). By the way, it is not possible to remove it entirely, but only unscrew the two lower mounts, then it can be moved without damaging.

Tags and direct adjustment

When the preparation is completed and the car is ready to work with it, you can begin to set the Ignition Tags VAZ 2114. Procedure Procedure Check the synchronization of the system (Correlation of the camshaft, crankshaft and the moment of injection), with some nuances for electronic system.

For electronic ignition systems, there is a small nuance - the need to check the distance from the specifying disk to the sensor. Normally, this distance should not exceed 0.7 mm, but not less than 0.5 mm. You can use probe for valves to check.

Further procedure for electronic ignition system looks like this:

Useful video

Interesting information you can learn, viewing additionally the video below:

The ignition module accepts the control pulse from the control unit and transmits it to the cylinder candle to ignite the air-fuel mixture. The device itself consists of two coils that produce, and a two-channel switch. The body of the product is made of durable plastic.

Violations in this element can be manifested as follows:

Noticeable decrease.
Lack of spark on one of the candles.
Noticeable "swimming" idling.

These features show that malfunctions have arisen in the operation of the ignition module. If they manifested themselves, it is worth replacing the ignition module.

What if after replacing the module malfunction remained?

First of all it is necessary.

Checking the ignition module

Resistance between contacts: 1 and 4, 2 and 3 - should not being above 5.8 com!

If, after replacing the ignition module, nothing has changed, it means that others are faulty.

Candles and ignition system

If it does not help, then you need to check the candles and, if necessary, replace(cm. ).

Inspection of the state of spark plugs

If the replacement of the module has not corrected the position, and. This means that rings or pistons were worn outThey need to be replaced, and candles clean and install back in the connector. It is also worth checking - too long a distance affects the operation of the devices.
