Ignition coil viburnum 8 cl malfunction

Checking the serviceability of the ignition module Lada Kalina

The procedure and nuances of connecting high-voltage ignition wires. Subscribe to the channel Wires must be resistant to aggressive...

I’ll quickly and clearly tell you how to check the ignition module 042.3705, which is used on VAZ 2108-15, ZAZ-Sens, Slavuta cars. Described..

As already mentioned, when the first signs of malfunctions appear in the VAZ-2114 ignition module, the vehicle owner should diagnose it.

Checking the ignition coil and its circuits

Misfires during engine operation can be caused not only by faulty high-voltage wires, but also by failure of the ignition module. To identify a malfunction of the ignition coil on the Lada Kalina, we will need a multimeter with which we will measure the resistance at its contacts.

The passenger car ignition module is specially designed to improve the starting of a car engine. Since two high-voltage coils operate as the main components of the module, it is often called the “ignition coil”.

The ignition module is controlled by the ECU, which supplies constant voltage in the form of low-voltage control signals to the windings of its coils at the right moment. The end of the signal is the beginning of the spark. Thanks to magnetic induction, at the moment of application, a high voltage is generated, creating a spark at the spark plug.

If one or more cylinders in the engine do not work, acceleration failures are possible. The car will twitch and vibrate.

Operational Aspects

Frequent cases when owners call for service are when the coil fails or does not function correctly. You can also diagnose the ignition module yourself. To do this you will need to acquire the appropriate equipment. One such diagnostic tool is a multimeter. It is used to measure the actual resistance value at the coil terminals in the 8-valve versions of the Lada Kalina, as well as in the 16-valve version. In order for the results of measuring actions to have maximum correctness, the procedure should be followed at least twice.

Damage to the ignition system can occur in any part of the circuit. This circumstance requires maximum care and attention during diagnostic procedures. The check begins with making sure that the winding is connected correctly to ground. Now let's diagnose the central terminal of the coil. We apply the positive contact of the device to it, and connect the negative contact with the vehicle ground. We look at the screen. If there is a symbol of infinity resistance, then this indicates the absence of a short circuit on this section of the circuit. From this information, the owner must conclude that the ignition module is working.

Check if the winding is shorted to ground

Note! By the way, when you disconnect the high-voltage wires, then also disconnect the wiring block from the module; for clarity, in the photo above it is indicated by a red arrow, and it is very easy to disconnect, just press the latch that secures it and then you can disconnect the block!

Often the reason for many calls to the service station is not so much malfunctions in the high-voltage wires, but rather the incorrect operation of the Kalina ignition module. To carry out diagnostics, you can go to a service center or pick up the tools yourself. One such is a multimeter used to measure the actual resistance level on the 8-cell pins. engine. The ignition module of a modern car performs the function of generating high voltage to produce a spark at the spark plugs. It consists of two coils with a closed magnetic circuit and a two-channel switch. Sometimes the switch is made as a separate device, but in most cases it is combined with an electronic control unit for the engine.

Ignition module: check and signs of malfunction

The exception is diesel engines. In them, ignition occurs due to high air compression. However, in cars with a gasoline engine, of which the majority are on the road, the ignition coil often fails. Signs of a malfunction may vary.

A break in the gas distribution pump drive is possible due to a jammed water pump. It is recommended to replace the water pump assembly. To prevent the vehicle from overheating, you should periodically check the operation of the pump. At the first signs of pump failure (extraneous noise, coolant leakage), you should immediately check its functionality.

Engine trouble is a very common problem in fuel-injected cars, one of the reasons for this is...

Worn tie rod ball joint is a common cause of steering failure. At the same time, a crunching sound is heard. The problem is due to a small amount of lubricant. In this case, the CV joint must be replaced.

If the ignition module is faulty, try repairing it yourself. If the MZ turns out to be in good order, the cause of the engine malfunction may be in the high-voltage wires (check) or spark plugs (check). Let us remind you that we previously told you how you can improve the ignition spark.

Let's sum it up

If the results of the diagnostic actions of the LADA Kalina car reveal that the ignition coil is faulty, then replacing this unit is a very simple undertaking. To implement the process, you will need a hex wrench. Before dismantling, we recommend that you remember the location of the high-voltage cables at the corresponding coil terminals. This will eliminate switching errors when installing the device.

The car jerks, there is no traction, vibration is felt, or the engine is rough; all these are symptoms of improper operation of the individual ignition coil (IIC). Other signs of a faulty ignition coil are the presence of errors 0301, 0302, 0303 and 0304, indicating misfire in one of the cylinders. Let's look at a few simple ways to check the ignition coil with your own hands.

It is worth noting that the process of checking IKZ on modern Lada cars (XRAY, Vesta, Largus, Granta, Kalina and Priora) does not have significant differences. All actions are performed in the same way.

Operating principle of the ignition module

It all started when, on the way home from work, for no apparent reason, the engine started to misfire and stopped pulling. Before this, a check light came on on the dashboard, after blinking several times. The problem was solved by stopping and restarting the engine. A few days later the same thing happened again. I decided to diagnose the car.

Operating a car with such a breakdown is possible (you can drive to a garage or car service station), but it is not advisable unless absolutely necessary.

Despite the high reliability and durability of the ignition module, during operation it can fail, like any other mechanism.

How to diagnose the ignition coil on a VAZ-2114

Diagnostics is carried out in several stages. First of all, the winding is shorted to ground. The multimeter must be set to check the resistance so that it works like an ohmmeter.

Experts note the main symptom of a faulty ignition coil is the absence of an igniting spark on the spark plugs.

Car enthusiasts have repeatedly tried to modify the car's transmission. For example, in tuning the VAZ 2109 brand, the transmission played an important role.

Some gasoline engines that are installed on modern domestic and imported cars are equipped with ignition modules, which are a pulsed high-voltage current source.

The peculiarity of the device is that it uses a spark distribution method, which is called the “idle” spark method. The cylinders are divided into pairs. A spark is produced in each cylinder of the cylinders.

High fuel consumption. Since one cylinder is not working, the remaining three (or more depending on the engine design) take on the entire load. Accordingly, in order to resume the previous power, the motor will require more energy.

Transformers are controlled by a controller using powerful transistor valves. It receives a reference signal from the crankshaft position sensor, on the basis of which the firing sequence of the coils in the block is calculated.

The low cost of the Lada Kalina-1 car determines the rapid wear of spare parts. However, repairing, for example, a VAZ 2109 gearbox with your own hands is quite simple, since parts are much easier to find than for other cars.

In this case, you will need to carry out a different sequence of actions. And below I will try to describe this procedure in more detail:

It is necessary to connect the device wires to the module contacts, which are located at the edges. That is, to the extreme left and right. You can take a closer look at the photo below.

With new spark plugs, the engine began to run more stable, but after a few days the misfire error popped up again. After some more searching on the Internet, I decided to check the ignition coil and armored wires. You can find out how to do this from the car’s operating instructions; there are detailed instructions there, so I won’t give them here.

Also note that if the car does not start at all, this is not a sign of a coil failure. The fact is that there are several of them in the engine. Usually each cylinder has its own coil. On older ones, voltage is generated on two cylinders at once. Therefore, the motor will work until the last minute. If the car does not start at all, all the coils could fail at once. However, this is unlikely.

Floating speed: The situation when the idle speed of a running engine without any action taken by the driver begins to change spontaneously is called “floating speed”. Moreover, they can vary their performance so much that the engine sometimes stalls.

The weak point of the ignition coils and modules is the secondary winding, which generates a high voltage pulse. A coil break or breakdown may occur in it. The following factors lead to this phenomenon:

use of low-quality or unsuitable candles;
operation with non-functioning high voltage wires;
frequent attempts to check the spark.

Connecting and replacing VAZ short circuit

The procedure for removing and installing the ignition coil on old VAZ models:

First, disconnect the central high-voltage wire leading to the distributor (ignition distributor).
Disconnect all power wires from the coil contacts. Since they are fastened with nuts, you will need an 8 wrench for this.
If you don’t know which wires to connect to which connector later, it’s better to immediately remember or mark them somehow, so that later during installation you can connect them correctly.
Unscrew the coil housing. It is attached to a clamp (clamp), which is pressed to the car body with two nuts.
After the work has been done, you can remove the ignition coil and replace it if necessary.

For new type VAZ cars:

We remove the “minus terminal” from the battery.
Remove the top protective cover of the engine. If the engine volume is 1.5 liters, then this part is missing and this step is skipped.
We remove the high-voltage wires from the coil.
Now, using a 13mm wrench, unscrew the two fasteners.
Using a 17mm wrench, loosen one bolt securing the coil.
We take out the module.
Use a hexagon to unscrew the coil from the holder.
Assembly is carried out in reverse order.

Particular attention should be paid to the connection, since high-voltage wires must be located in the strict order provided for by the design. If this is not done, the car will stall or the engine may not start at all.

How to check the ignition module

Ignition of gasoline in the cylinders of an internal combustion engine occurs using a spark generated by the ignition system. The ignition module is the main element of the system, creating a spark on the spark plugs using high voltage. Each car manufacturer develops and produces its own original module, but the principle of its operation is the same for all devices. During operation, deviation from the specified parameters or breakdown of the ignition module negatively affects engine operation until the power unit fails.

Rules for using the lock

Position 0 is fixed. The ignition key can be removed from this position. In this position, external lighting devices can operate, including fog lights, illuminating the road ahead of the car. The hazard warning system works, you can use high and low beams, and turn on the audio system.
Position 1 is fixed. The key cannot be removed from this position. The ignition is on. In this case, electrical power is supplied to all energy consumers of the vehicle, with the exception of the starter. Leaving the key in this position for a long time can drain the battery. Before turning on the starter, it is recommended to hold the key in this position for several seconds. During these seconds, the electric fuel pump will create the required pressure in the fuel system, which will greatly facilitate starting the engine, especially when it is cold.
Position 2—turn on the starter. The key does not lock in this position. When released, it returns to position 1.

Do not hold the key in the starter position for more than 10 seconds. If the engine does not start, you need to take a break for 10-15 seconds and try again. Do not hold the key in this position while the engine is running. While Kalina’s car is moving, it is prohibited to remove the key from the lock. If you do this, steering failure will occur due to locking of the steering column and a sharp deterioration in the functioning of the braking system.

If during operation of the car the key remains in the lock, then when the driver's door is open, a continuous trill will be heard, signaling this. If the ignition is completely turned off and the key is removed from the hole, but the side lights are on, short beeps will be heard when the driver's door is open. The lock is capable of blocking the starter from turning on while the engine is running.

Purpose and principle of operation

Ignition module VAZ 2110

The ignition module of a modern car performs the function of generating high voltage to produce a spark at the spark plugs. It consists of two coils with a closed magnetic circuit and a two-channel switch. Sometimes the switch is made as a separate device, but in most cases it is combined with an electronic control unit for the engine. Externally, the modules differ in the number of wires in the connection connector: a module with a switch has 4 wires, and paired coils have 3.

Video on repairing KZ VAZ

The model of the domestic manufacturer is extremely in demand among car enthusiasts in Russia and the CIS countries. This is due to its moderate cost and ease of maintenance. However, a characteristic disadvantage of the car is unreliable wiring. The standard Kalina pinout is made in the form of 4 separate zones, united into a single whole by connecting harnesses.

The front part is a “web” that combines the battery, dashboard, generator and optics.
The instrument panel bundle is arranged to connect the front and rear compartments with the ECM, fuses and the instrument itself.
The aft branch contains outputs from consumers in the doors, aft dimensions, license plate lighting, and trunk lid.
The fourth section is responsible for powering the engine management system. This is where the ECU meets the relays and fuses. Sensors with instruments and indicators are also connected.

It should be noted that some design elements are interchangeable with other VAZ models. If any component fails, it is allowed to use components from other modifications of the automaker to repair the car.

Signs of a malfunctioning ignition module

Checking the ignition module with a removed spark plug

A malfunction of the ignition module is determined by the following symptoms:

Difficulty starting a cold engine due to lack of spark on one or more spark plugs.
Floating engine speed at idle is a situation in which the speed changes without any action on the part of the driver.
Dips in power, which manifests itself during acceleration and driving up a long climb.
Decrease in engine power.
Cylinders 1-4 or 2-3 do not work (engine “troits”).
Indication of the “Check Engine” indicator.

Possible causes of ignition module malfunction

Despite the high reliability and durability of the ignition module, during operation it can fail, like any other mechanism. Among all possible causes of breakdowns, in 9 out of 10 cases the following occur and are diagnosed:

Use of inappropriate components in the ignition system. High-voltage wires are selected based on the parameters of the module, since excessively high or low voltage creates malfunctions or burns out contacts.
Defective or damaged parts, poor quality assembly. Defective components break down faster and damage other components or elements of the system. Practice shows that the selection of high-quality components and their periodic diagnostics allow the module to remain operational for a long time.

Misfire video

The ignition coil in the 8-valve version of the Lada Kalina power unit, as in the 16-valve version, plays a primary role. It allows the engine to start easily even in very unfavorable climatic conditions. This circumstance encourages owners to pay increased attention to this product. Even a minor deviation in the functioning of the coil can immobilize the car for a long time. To minimize the risks of such a situation, we urge owners to follow the manufacturer’s regulatory recommendations. If the owner neglects this aspect, he will provoke himself into replacing the coil, which is very expensive. And in general, the ignition system must be maintained and operated carefully.

Checking the ignition module

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

Replacing the ignition module with a known good one

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

Checking the contacts on the ignition module

2. Moving the module, which allows you to identify unreliable contacts. To do this, move the wire block and the module itself. If during exposure the engine reacts by changing its operation, then the cause of the problem lies in poor contact.

Measuring resistance at the terminals of the ignition module

3. Resistance measurement. To do this, you will need a tester switched to ohmmeter mode. Measurements are carried out on the paired terminals of the module between cylinders 1 and 4, as well as cylinders 2 and 3. The resistance value should be the same and approach 5.4 kOhm.

Checking the ignition module using a tester

4. Check the voltage with a tester. One probe of the device is applied to contact A of the block, the second to ground. After turning on the ignition, take readings from the device. If the wire is in good condition, it will show a voltage of 12 V; if it is missing, check the fuse protecting the ignition module. Then check the continuity of the circuit with a 12 V test lamp. Apply one end of the wire to contact A and rotate the starter. If the lamp does not blink, the circuit is broken. The procedure is repeated in a similar way with other contacts.

Diagnostics of the ignition module with professional equipment

5. Diagnostics at a service station by connecting a computer with special software to the computer. Malfunctions are detected in the form of errors indicated by an alphanumeric code, after which a more in-depth diagnosis of the malfunction is carried out to make a decision - repair the ignition module or replace it. A similar check is carried out at a specialized service station using an oscilloscope.

Diagnostics of Lada Kalina wires

Signs of a malfunction of the VAZ-2110 ignition module

Before connecting high-voltage wires on Kalina purchased at a car dealership, you need to assess the current state of the car's wiring. For diagnostics, the car owner will need an analog or digital multimeter.

Before connecting the device, you need to inspect the wires for external defects. These include:

ruptures;
abrasions;
cracks;
broken.

If no external damage is observed, you need to connect a multimeter. You need to check the resistance of the armor wire, so you need to switch the device to ohmmeter mode. After this, the armored wire is disconnected from the spark plug and ignition coil. The ends of the wire are connected to the contacts of the multimeter, after which the device will show the current resistance level.

Data on normal resistance values are applied to the insulating layer. For passenger cars, normal values are in the range of 4-10 kOhm. In this case, on one specific car, the data values for individual wires should not differ by more than 2.5-3 kOhm. If this threshold is exceeded, then there is a problem in the ignition system.

There are several ways to check the functionality of the wiring without using measuring instruments:

Use of additional insulated wire. You need to strip both ends of the additional wire. Short one end to ground, and run the other bare end along the caps, joints and the entire contour of the wire being tested. If there is a defect, the tester wire will give a spark;
You need to drive the car into an unlit box, open the hood, and start the engine. If there is a breakdown in the VP insulation, the damaged area will spark.

The easiest way is to take a working high-voltage wire and test it on each cylinder by elimination.

Repair

Ignition module VAZ 2107

The design of the ignition module is quite complex: it includes one or more coils, a board, contacts and wires. Of all the above elements, only contact connections can be repaired; in some cases, replacement of parts (transistors, coils) is possible.

The module is dismantled and opened for repair purposes. For this you will need:

Socket wrenches with heads 1, 13 and 17.
Hexagon 5.
Screwdriver.
Soldering iron.
Flux for aluminum.
Stranded wire.
Nail polish.

Opening the ignition module

Repair of the ignition module is carried out in the following order:

On the removed device, open the case by prying it off with a screwdriver.
Remove the silicone film covering the board.
All aluminum is removed from the explosive contacts.
On the board, new wires are soldered in place of all the dismantled old ones. To do this, the surface of the collector is cleaned of deposits, after which the board is heated to 180 o C (a characteristic smell will indicate when the desired temperature has been reached). During the soldering process, the ends of the wires are connected to the module.
At the end of the operation, all contacts, the board and the module are covered with nail polish.
The device is assembled in the reverse order, installed on the car and the engine is started. In case of normal operation, the ignition module is sealed tightly with sealant, while the wires are tucked inside the cavity so that they are not pinched at the edges by the plate.

If the device does not work, then a breakdown inside the module should be looked for more carefully. The transistor, electronic component may have failed, or there may be a break in the coil. Such a repair makes sense only if its price is significantly lower than the cost of a new part.

Ignition switch and features of its replacement

The ZZ is secured with one screw and is located on the steering column on the right under the steering wheel. Its design includes a locking device and a contact group. They are interconnected, working synchronously, and are activated using the ignition key.

When diagnosing faults in the electrical circuit, it is necessary to check whether the contacts close correctly when the position of the key changes. If any irregularities in the operation of the ignition protection are detected, it should be replaced (the author of the video is Renault Repair).

The procedure for replacing the ZZ on the Lada Largus consists of the following steps:

Before work, disconnect the negative terminal from the battery to turn off the power supply to the car.
Next, remove the steering column casing.
At the next stage, by releasing the latch, we disconnect the connector with the wires of the contact group.
Then, inserting the key into the ignition switch and setting it to the first position, remove the 33 wires from the dashboard.
Next, unscrew the bolt that secures the ZZ.
Use a screwdriver to press out the latches and remove the 3Z from the housing.
We dismantle the faulty unit.
Having installed a new spare part, we assemble it in the reverse order.

Purpose and principle of operation

Ignition module VAZ 2110

Selected aspects of technical operation

Many inexperienced drivers, not understanding the essence of the breakdown, decide that an expensive replacement of the ignition switch or the wiring as a whole is necessary. Experienced drivers advise not to rush to conclusions. If, due to various circumstances, the ignition coil fails, the corresponding indicator lights up on the dashboard. The first thing the driver should do in such a situation is to drive the car into the garage and open the hood.

Often spark plugs fail due to a power surge or short circuit. As a result, the spark does not travel properly throughout the system. A number of other circumstances can cause a similar problem:

the car was damaged in an accident;
replacement of spark plugs may be required after lightning strikes the car;
poor-quality previous repairs;
use of non-original spare parts;
failure to comply with technical inspection deadlines at the service center.

Often the reason for many calls to the service station is not so much malfunctions in the high-voltage wires, but rather the incorrect operation of the Kalina ignition module. To carry out diagnostics, you can go to a service center or pick up the tools yourself. One of these is a multimeter used to measure the actual resistance level on the 8-cell pins. engine. To obtain correct measurement results, it is necessary to carry out 2 times.

The ignition system can be damaged in any part of the circuit, so monitoring must be careful. It all starts with checking that the winding is properly connected to ground. It is necessary to carefully insert the contacts, focusing on the indicators of the device. Then one of the contact terminals of the device is connected to the central contact of the spark plug coil. In this case, the second contact is attached to ground.

Ignition coil malfunction factors

When the first signs of a breakdown appear, inexperienced owners first of all suspect the ignition switch or high-voltage wires as the culprit. Owners of Lada Kalina with experience recommend a balanced approach to resolving the issue. How to check the fault? If the coil fails, the dashboard will remind you of this by means of an indicator light.

A voltage surge or a short circuit inside the unit can cause damage to the spark plugs. In this case, the spark will not be able to generate correctly between the electrodes.

Device failure can also be caused by the following factors:

the car getting into an accident, as a result of which you can observe the destruction of some components of the ignition unit;
the car was struck by lightning;
the previously completed repairs turned out to be of poor quality;
use by the owner of non-original components in the designated system;
ignoring maintenance intervals.

Regardless of the reasons, the owner of the Lada Kalina should diagnose the ignition system in detail. Sometimes a problem can be generated by the influence of several negative factors at the same time. This situation warns an inexperienced driver to tend to independently search for and eliminate breakdowns, because there is a likely risk of forced failure of other known-good components.

Cylinders 1-4 or 2-3 do not work (engine “troits”).
Indication of the “Check Engine” indicator.

Use of inappropriate components in the ignition system. High-voltage wires are selected based on the parameters of the module, since excessively high or low voltage creates malfunctions or burns out contacts.
Defective or damaged parts, poor quality assembly. Defective components break down faster and damage other components or elements of the system. Practice shows that the selection of high-quality components and their periodic diagnostics allow the module to remain operational for a long time.

Priora, 2170-2173

The Lada Priora is equipped with the same ignition coils as the Kalina. The coil is marked 2112-3705010-12. Just as in the case of Kalina, Priora is equipped only with injection engines, so carburetor ignition coils or “bobbins” cannot be installed on the car.

To summarize, it is worth saying that when choosing an ignition coil for a car, it is necessary to take into account the marking of the part, its compatibility with a particular model of the domestic automobile industry. Despite the high interchangeability, attention is also paid to the overall dimensions of the part and the type of fastening in the engine compartment of the car. You can purchase coils or ignition modules for domestic “classics”, “Samara” and “Sputniks” in our online store with a few clicks of a computer mouse.

Kalina is a car of the famous AvtoVAZ and is equipped with two types of engines: 8 valve and 16 valve. The difference in these engines is quite significant, both in power characteristics and design.

Depending on the type of engine installed, the spark formation system in the combustion chamber also changes. For example, in 8-valve Kalina engines, an ignition module is used that is responsible for 4 cylinders at once, but in 16-valve engines, individual ignition coils are used, that is, each cylinder has its own coil, which is responsible for the formation of a spark in that particular cylinder.

Since this article is devoted to the ignition system of the Lada Kalina car, namely the ignition coils, after reading this article you can easily check your car’s coil for malfunction and possible failure.

Checking the ignition module

Replacing the ignition module with a known good one

Checking the contacts on the ignition module

Measuring resistance at the terminals of the ignition module

Checking the ignition module using a tester

Diagnostics of the ignition module with professional equipment

Checking the secondary windings of the module:

So, we take the ignition module of the Lada Kalina and turn it so that the conclusions of the high-voltage wires are facing us. Now we connect the device wires to the outputs of the 1st and 4th cylinders. And then we check the 2nd and 3rd cylinders in the same way.

All these testing procedures are best carried out with the module removed; this is much more convenient than doing everything directly under the hood of the car. Removing this part is quite simple, you only need a 5 hexagon and a couple of minutes of time.
