Each wire color on the diagram and in the car corresponds. Therefore, looking at the device, you can easily determine where you need to connect which one. But, even with a scheme, many motorists are confused in this matter. Based on this, we can conclude that if nothing is clear, then you should contact the professionals who will understand the pinout of the wiring and connect everything quickly and efficiently.
Injector connection diagram
It is quite difficult to tell in words the pinout of the wires for connecting the injector to the ignition system, so you should pay attention to the diagram below.

conclusions
It is worth noting that all electrical equipment of the VAZ-2114 passes through the ECU and the fuse box, so it is necessary to track the wiring that goes to the ignition. All the wires are marked on the diagram in color correspond to the colors in the electrical equipment of the car, so it is not possible to be confused.
The ignition module on the VAZ 2114 and on other VAZ models is designed to supply high voltage through the high voltage wires (high voltage wires) to the spark plugs. Some of the car owners call the ignition module a coil, which is not entirely correct.
Ignition coils were installed carburetor vases... It is the ignition module that is used on the VAZ 2110-15.
The main function of the ignition module
The main task of the module is to supply current to the spark plugs. During operation, a working spark is supplied to one candle, and a "blank" spark to the other. The working spark is fed to the 1st and 4th cylinders, and the idle spark is fed to the 2nd and 3rd. Due to such a connection, a spark appears in a timely manner in the desired cylinder during the required cycle. It is connected to the on-board network.
Principle of operation and location
The ignition module is controlled by a controller, which in turn receives information about the state of the car from various sensors (and others). The controller also sets the sequence of the ignition coils, or in other words, regulates the supply of current to the spark plugs. The ignition module operates at temperatures from -40 ° to + 130 °.
Finding its location is not difficult, from the module to the candles there are PVN (high-voltage wires) along which you can find the module.
Malfunction of the ignition module - the first signs of failure
- Lost engine thrust - the car "does not pull"
- Float turns
- The engine is "troit", that is, one or two cylinders may not work
- Acceleration dips
If you notice that the car does not pull, that is, it does not pick up speed during acceleration, one of the reasons may be a module failure. First of all, it is worth checking the NVDs coming from the coil to the candles. Perhaps some wire flew off the tip or loosely dressed.
Diagram of the correct connection of wires to the ignition module
If, after checking the wires, you are convinced that they are all tightly dressed on the candles, check the correctness of the connection of the wires themselves. Of course, if no one climbed into the engine before you, then there is no point in checking. If the thrust was and disappeared, the reason may be both in the coil and the wires themselves - they can be punctured. But in any case, let's check the correctness of the connection. The numbering of the cylinders to which the wires fit is indicated on the ignition module.
- 1 cylinder - center bottom outlet
- 2 cylinder - left exit
- 3 cylinder - top outlet
- 4 cylinder - right exit
The diagram is shown for the coil installed on the car.
If, after checking, no problems are identified, it is worth considering replacing the coil or wires. It is desirable to change both.
The cost of PVN, depending on the manufacturer, ranges from 300 to 600 rubles per set. Most popular manufacturers:
- TESLA
- BRISK
- BAUTLER
- Egorshinsk
The cost of the ignition coil is from 1300 to 2500 rubles. Modules from the following companies can be found in stores:
- SOATE (St. Oskol)
- MZATE
- HOFER
- FENOX
- BOSCH
When choosing a module, you should pay attention not only to the manufacturer, but also to the coil itself, it can be of the old and new model. Therefore, it is better to dismantle your own and bring it to the store.
Ignition module error codes
When diagnosing a car, the following error codes will be useful to you
- P0351 - open coil 1-4 cylinder
- P0352 - breakage of the coil of 2-3 cylinders
- P3000 (P3001 P3002 P3003 P3004) - multiple misfires.
DIY ignition module replacement
So, first of all, we are looking for a module (for those who do not know). To him go DPS from spark plugs.
- Remove the negative terminal from the battery
- Disconnect the block of wires from the module
- Disconnect the PVN
- We unscrew the module itself and remove it
- Now we install the new module and carry out the assembly in the reverse order.
When installing, do not confuse the position of the PVN on the coil.
Useful note! If you are installing a new coil and old wires, pay attention to them. If there are yellow stripes on the tips of the candles and wires, then the wires must be replaced.
After replacing the module, it is necessary to check its operation. We start the engine and enjoy the work done.
In the article brought to your attention, we will pay attention to an electronic device called the ignition module of the VAZ 2115 car. Or, more precisely, its description, schematic diagram and health checks.
The device of the ignition module VAZ 2115
This module includes two high-voltage transformers and two control units (electronic), enclosed in a robust plastic case with four high-voltage leads. Electronic control units are also called ignition coils, and one of them - "working" - is connected to the spark plugs of the first and fourth cylinders power unit, the other - "blank" - with the candles of the second and third.
This type of connection, made with high-voltage wires, provides synchronous "skipping" of the spark pulse in the cylinders of the power plant.
Thus, we can formulate functional purpose Ignition Module - Generates high voltage spark pulses on the powertrain spark plugs vehicle.
The "VAZ 2115" ignition module is controlled by a controller, the working functions of which include processing data from the vehicle system sensors: coolant temperature, rotation speed and position crankshaft, air consumption, detonation, etc.
Ignition module diagram 2115
The schematic diagram and connection diagram of this electronic device is presented below.
Ignition module installed on " Lada samara", Is extremely resistant to both low and high temperatures... Operating temperature range: -400 / + 1300C.
The only negative point in the operation of this electronic device is its complete unrepairability. However, even a novice car enthusiast can independently perform its replacement.
Experts consider the most common malfunctions of the Samara ignition module:
Unstable operation of the power plant during vehicle acceleration.
Loss of engine power.
"Intermittent" idling.
Violation of the performance of paired (1/4 - 2/3) engine cylinders.
Attention! The detection of the above malfunctions is not a definitive indication of the failure of the ignition module, since such symptoms are possible in the event of malfunctioning spark plugs and unreliable connection of high-voltage wires.
Checking the ignition module "Lada Samara"
The correct functioning of the ignition module not only has a significant effect on starting the vehicle's power plant, but also ensures the stability of its operation in all modes. To carry out a complete diagnosis of this electronic device, a rather sophisticated equipment is required, which is available only in large specialized workshops. Nevertheless, the performance check of the ignition module can also be carried out in an amateur garage on your own. The only logistical support for this test will be a multimeter, or tester.
The first and most in a simple way determining the operability of the ignition module is its substitution with a knowingly serviceable device.
Attention! When using the donor car for checking, do not forget that only the first Lada Samara models were equipped with the ignition module, as a separate device. Later machines are equipped with split type devices (the switch is included in the electronic unit management).
The procedure for replacing the ignition module includes the following:
Preparation the necessary tool: wrench for "17" (open-end), wrench for "13" (open-end), wrench for "10" (socket), hexagon.
De-energizing the vehicle by disconnecting the "-" terminal from battery.
Dismantling the block of wires.
Disconnection of high voltage wires.
Unscrewing the fasteners to the power unit.
Removal of the ignition module (it is turned away from the holder with a hexagon).
Installing a replacement module involves connecting high-voltage wires (the module case contains tips). In addition, the wire terminals are also labeled accordingly. We install the ignition module, performing manipulations in the reverse order, followed by checking its operability.
Another method involves measuring the resistance of individual elements of the module using a multimeter (tester). Using the tester's probes, we close the “paired” terminals of the module, which ensure the connection of high voltage wires, and measure the resistance value.
The resistance value of a working device should be approximately 5.4 kΩ. Inconsistency this parameter this value indicates that the VAZ 2115 ignition module is inoperative.
There is one more, the so-called "folk" method, or the "shake-up" method. When running power plant lightly knock on the module. For all the "technical unscientific nature" of such manipulations, they are capable of giving a result. True, only in the case when the contact of the elements inside the case is broken.
Since the VAZ 2114 and 2115 cars are almost completely the same, the principle of replacing the ignition module will be completely identical, since the design of the engines of these cars is the same.
Ignition Module Malfunction Symptoms
When a malfunction occurs with the ignition module, the following problems may appear:
- The engine has dips, especially when driving
- Unstable rpm and a feeling of failure of one or more cylinders
- Continuous interruptions in the ignition system
To replace this part on our own, we need the following tool:
- end head 10 mm
- ratchet handle or crank
DIY instructions for replacing the ignition module on a VAZ 2114
The first step is to turn off the car power by removing the "-" terminal from the battery. Then we remove all high-voltage wires, as clearly shown in the photo below:
After that, slightly bending the plastic retainer of the plug, take it away from the module.
After that, unscrew the three coil mounting nuts. Two are on the same side, and they can be clearly seen in the photo below:
And one more on the other side. After you have also dealt with it, you can dismantle the old ignition module without any difficulties.
And finally we take it out of the engine compartment of the VAZ 2114.
After buying a new one, we install in the reverse order. The price of a new ignition module for a VAZ 2114 is from 1800 to 2400 rubles. The difference in cost depends on the type of coil, as well as on the manufacturer.
It is worth noting that when removing an old part, you need to read and write down catalog number spare parts to take the same when buying. Otherwise, there may be problems with the compatibility of the ECM components.
When self-diagnosing the engine, its systems and characteristics, a minimum of equipment is used. For example, before checking the ignition module, it is advisable to have a special stand required software or as a last resort - an oscilloscope. None of us has and never will have such equipment, so for preliminary checks we will use available tools and devices.
How to check the ignition module VAZ-2114
Interruptions and jerks when driving, a triple engine, difficult starting or even engine failure are the main signs of failure of the ignition module.
Ignition module
The difficulty of diagnostics on your own is that several devices are combined in the module at once, and it itself is made in a single case and there is no way to check each device separately. At least with bare hands. Nevertheless, there is something that can be done in order to, if not repair, then at least be sure to know about the cause of the malfunction.
Checking the quality of contacts
First of all, without dismantling anything, it is worth checking the quality of the contact on all pads of the low voltage circuit, and also establish the presence of a contact on the high voltage wires.
Checking the presence of power on the ignition module
We check the voltages on the pads of the ignition module
In order to know that it is the module that is faulty, check if it is receiving power. To do this, we find the connector in the block, and there we are looking for a contact marked with the letter A. To control the power supply of the module, we take a multimeter, set it to the mode of measuring alternating current up to 20 V, install one probe (negative) to the engine weight and turn on the ignition. The second probe is installed on terminal A on the block. If the electrical equipment is in good working order, the multimeter will show 12 V, which means that power is being supplied to the module, we are looking for the cause of the malfunction further.
Checking the connector pins
We have already carried out a preliminary check and made sure that the ignition module is powered. Now it's worth dealing with contacts separately. With the ignition on, you need to connect a test lamp to contact A and contact V.
The test can be an ordinary low-power 12-volt lamp with soldered wires, or you can use a car test probe with a 12V voltage indicator.
Checking the ignition module
To check the functionality of the module we attach the contacts from the test lamp or probe to the terminals A and B, after that we turn the engine with a starter.
If the lamp starts blinking, the module gives a break in voltage by analogy with a contact breaker.
In this case, pins A and B are all right.
If the lamp does not respond to starting the starter, the module is clearly defective.
Checking module 2114 using available methods
Most effective method find out that the ignition module does not work, take a known working device and try to start the engine on it. It is clear that not every module from eights, nines and second generation Samar can fit.
The algorithm of action for subsequent verification is as follows:

conclusions
Like any non-repairable device, the ignition module most often needs to be replaced ... So you can save a lot of time and nerves, which are not worth the money that is asked for a new module. Successful work to all!
