How to check the serviceability of the ignition coil?
Malfunctions of the ignition module lead to unstable engine operation and the inability to start the car. The module's task is to generate high-voltage pulses and transmit them to the spark plug (SZ). The plus of the unit receives + 12V power from the on-board network, the minus is taken from the car body.
Ignition coil for Lada Kalina
The design of the ignition module for 8 and 16 kL Lada Kalina engines includes two high-voltage transformers (coils) and two control units. One coil is connected to cylinders 1 and 4, and the second to cylinders 2 and 3. The device is connected to the SZ using high-voltage wires.
Check if the winding is shorted to ground
This diagnostic stage is done quite simply and will not take much time. The main thing is to connect everything correctly.
- First, we set the position of the pointer of the device for measuring resistance; I think there is no need to explain this in detail.
- Then you need to connect one contact terminal of the device to the central contact on the coil, and connect the second to ground. If you explained something incomprehensibly, then you can see how it all should look visually in practice. The photo below shows everything perfectly.
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.
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.

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.
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.
How to remove the ignition with your own hands?
It is better to check the functionality with the device removed. On an 8-cl engine, the ignition module is located in the front of the car.
Location of module 8 cells
On an engine with 16 cells there are 4 modules and they are located in a different place.
The device removal procedure consists of the following steps:
- First of all, you need to de-energize the car by removing the negative terminal from the battery.
- If the engine has protection, it must be removed.
- Next, press the latch and disconnect the wire block from the unit.
- Then we disconnect the four high-voltage wires and put them aside so that they do not interfere.
- Next, using a key set to “13” you need to unscrew the fastenings of the module to the motor.
- Use a hex screwdriver to unscrew the mounting bolts and remove the device from the engine.
Depending on the tester’s performance, the issue of replacing the device or repairing it is decided. Before installing the module in its original location, its mounts and the engine housing mounts should be cleaned, which will improve the transmitted voltage across the ground. After installation, it is necessary to check the functionality of the engine ignition system.
In order not to make a mistake when connecting high-voltage wires, you need to check the numbers on the block with the numbers on the wires; they must match. You should buy a new module with the same markings that were on the old one. To do this, you need to remember it when removing it. Then there will be no problems when installing a new device.
Location of the marking
Regardless of which engine is installed on the car - 16 cl or 8 cl, checking the coils is the same. If you know how to check the coils of an 8-valve engine, you can check a 16-valve engine. This knowledge will help you save on visiting a car service center.
About the Kalina ignition system
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 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.
The cause of misfires in the operation of the power unit may be not only damage to the high-voltage wires, but also to the ignition module. The article gives recommendations on how to check the ignition coil on a Lada Kalina car with an 8 and 16 valve engine.
