The image shows 4 actuators. Also, control unit 3 has a special designation. It is noted that actuator 7 is located in the door on the driver’s side.
This scheme may also seem elementary to the master, but there is a significant fact that is not always taken into account by the creators of the notation. The white cord in the image marks the process of opening the lock, the brown one, in turn, closes the system.

How to check the ignition coil of a VAZ
If the ignition coil is faulty, the engine will not start. A characteristic sign of a faulty coil is its increased temperature when the ignition is turned off. This is easy to determine by touch.
Signs of a faulty ignition module may include the following:
- hesitant engine starting or failure to start;
- failures during sudden changes in speed;
- high fuel consumption;
- two cylinders do not work, the engine is feverish;
- lack of dynamics;
- a sharp drop in power;
- drop in power and thrust after warming up.
These symptoms may not only be caused by the ignition module. To determine the malfunction, it is enough to spend a few minutes diagnosing spark plugs, high-voltage wires and caps. This will eliminate the remaining elements of the ignition system and make sure that it is the ignition module that is faulty.
Checking the ignition coil is performed in one of 2 ways. The simplest one is to remove the central wire from the breaker-distributor, bring it to the motor housing and turn it with the starter, and a running spark should appear. After this, we check the energy supply to a separate spark plug, for which we unscrew the working spark plug, bring its contact to ground and attempt to start the engine. In this case, the spark should come from the wire to ground. If it is absent, the reason will be a malfunction of a system element such as the ignition coil.
To check the module in the second way, we only need a multimeter, then follow the step-by-step instructions:
- We check the power supply and the presence of pulses supplied from the ECU. We check the power between the central terminal (15) of the wire block connected to the module and the engine ground. When the ignition is on, the voltage should not be less than 12 V. Otherwise, either the battery is dead or the ECU does not work.
- We check the pulses from the ECU on the wiring block. We install one tester probe on connector 15, the second on the far right, then on the far left. The assistant cranks the engine with the starter, and at this time we record short-term voltage surges with a tester. If there are no impulses from the ECU, it is he who is to blame.
- We check the resistance on the secondary windings of the coils. We put the tester in resistance measurement mode and measure it at the high-voltage terminals of the module cover. Between pins 1 and 4 and pins 2-3, the resistance should be 5.4 kOhm. Otherwise, the module must be replaced.
- We check the resistance of the primary windings between contacts 15 and the rightmost, then the leftmost terminals. Nominal - 0.5 Ohm. Deviation is not allowed.
- Check the module for a short circuit. In ohmmeter mode, install one multimeter probe on the central terminal, the second on the metal body. There shouldn't be any resistance. If the device detects at least some resistance (other than unity or infinity), the module must be replaced.
Problems when paying with bank cards
Sometimes difficulties may arise when paying with Visa/MasterCard bank cards. The most common of them:
- There is a restriction on the card for paying for online purchases
- A plastic card is not intended for making payments online.
- The plastic card is not activated for making payments online.
- There are not enough funds on the plastic card.
In order to solve these problems, you need to call or write to the technical support of the bank where you are served. Bank specialists will help you resolve them and make payments.
That's basically it. The entire process of paying for a book in PDF format on car repair on our website takes 1-2 minutes.

There were no prerequisites for replacement. The original coil worked fine, well, almost normal. I didn’t like that the car was adjusting under constant load. Therefore, I decided to conduct an experiment on replacing the coil with something larger and more interesting. I looked at Oleg reekardo’s blog about replacing the coil and decided to go the same route, but make it a little more complicated. Without thoroughly reading the entry (and it says to buy a coil, not an ignition module from a VAZ), I went and first bought an ignition module and a connector for it. The same module was in my Niva.
I started connecting it, but it didn’t work—the car wouldn’t start. I built a mini test bench (4 spark plugs, wires and battery). The stand showed that the module was working. (And it was written to take a coil, not a module) I went and replaced the module with a coil (I also got the difference in price in my pocket 
Then it's easier. I found the necessary connection points and checked the operation. Then I soldered the wires to the original wiring. The original connector was wrapped with electrical tape. I mounted the module diagonally on the standard plate, just removed the wire fastening to the knock sensor and screwed the bolt into the vacant hole.
