Common faults
If there are malfunctions in the electrical circuit, the machine may behave differently:
- The car does not drive or start. Of course, there can be many reasons for such a breakdown, from the battery to the engine. Therefore, you should first diagnose the battery, distributor, and starter unit. In practice, most often car owners are faced with a discharged battery, much less often the generator breaks down, but it also needs to be checked.
- The vehicle is driving, but one or more network components are not functioning correctly. For example, the headlights, dashboard lights, wipers, and rear window heating system do not work. In this case, the unit with safety devices is first diagnosed to detect burnt elements. If all fuses are intact, then you need to check the wiring. Consumers - optics or dashboard bulbs, glass heating systems, windshield wiper motors, etc. - fail much less frequently.
If the car does not start at all, then you need to proceed as follows:
- As stated above, first of all, the battery is diagnosed - maybe the battery is simply discharged.
- Next, you need to check the section of the circuit that goes from the ignition coil to the generator. If there are breaks in this area, the wires will need to be replaced; if the contacts are oxidized, then they are simply cleaned; for this you can use a construction iron brush. Contacts need to be changed if they begin to crumble.
- You also need to check the spark plugs to see if a spark passes through them or not. To do this, you need to pull out one high-voltage wire and bring it to ground - the car body or the cylinder head. When the engine starter is turned with the key, a spark should appear between the wire and ground.
- If there is no spark, then the problem must be looked for either in the coil or in the spark plugs. To check the coil, you will need to diagnose the voltage at its terminals. As for the candles, there should be no signs of damage or soot on them. You can learn in detail about the reasons for the appearance of carbon deposits and cleaning spark plugs in this article (the author of the video is Denis Khafizov).

What kind of damage can occur in the ignition switch?
As mentioned above, practice shows that breakdowns are common to both parts of the lock and often require replacement of one or the other half. Sometimes VAZ 2106 ignition coils can fail
When servicing these elements, you need to know what a non-contact ignition circuit is, and after that you need to disconnect the negative terminal on the battery, except if you check the presence of voltage at consumers.
- Mechanical failure
The most common malfunction of the mechanical part of the locking system is a tight turn of the key; if the connection problem is not solved in time, the key will jam in the lock or break. As a result, you will have to change the entire lock, and such a replacement will require large expenses.
Factory ignition switches from VAZ 2106 cars very rarely break down in this way; such a malfunction is typical for Chinese spare parts, because the cost of the analogue is an order of magnitude lower. Analogs cannot be repaired, unlike spare parts from the LADA automobile plant.
If a car enthusiast encounters a similar problem, then in the future, as a rule, he already purchases an original spare part from AvtoVAZ, no longer trusting Chinese manufacturers of parts.
- Electronic failures
Often, malfunctions of the VAZ 2106 ignition switch are associated with the electronic part of the device and they also require replacement
In this case, it is important to remember that the connection diagram plays a huge role, and you should not mix up the wires.
The main causes of ignition terminal malfunction:
- Oxidation of contacts.
- Partial or complete combustion of wires.
Melting of the plastic part of the terminal.
These reasons are caused by poor terminal contact on the VAZ 2106, or by the fact that the starter starts for a long time.
In this case, it is only necessary to change the electronic unit, which can be purchased separately at auto parts stores.
When replacing, you need to remember or sketch the colors of each cable connected to the lock so that the diagram is at hand, or simply take a photo of the terminal with your phone. Each contact has a specific number. So, the connection can be made according to the diagram indicated on the manufacturer’s packaging box. If there is no diagram or it is lost, then read on.

We carefully inspect for damage; if any are found, it is better to immediately go to the store for a new one.
You can check this device yourself; to do this, you just need to determine the resistance of the windings. The ohmmeter reading should be between 550-570 Ohms. If the readings are correct, then perhaps it's all in the wiring. Check all wires and connections one by one. Do not try to repair the crankshaft sensor on VAZ cars - it cannot be repaired.
Before installation, be sure to wipe the shrinkage area, it should be clean from dirt and dust. Next, install the shaft sensor and tighten the bolt. After connecting the wires, the work can be considered complete. As you can see, the whole procedure is quite simple. If you want to get more information, or do not understand where the shaft is located, then watch the video we offer.
Historical excursion
The first-born of the Volga Automobile Plant, the VAZ 2101, first appeared on domestic roads in 1970. Then, from April to December, more than 21,000 cars were assembled, and in 1974, the annual production amounted to more than 370 thousand cars.
The automaker constantly improved the model, and as a result, the VAZ 21011 was born, for which:
- A more powerful engine with a volume of 1.3 liters was installed (for the VAZ 2101 it was 1.1 liters);
- The interior ventilation grilles were placed on the rear pillars;
- Turn signal repeaters and brake lights with special reflectors were installed.
For reference: the wiring diagram of the VAZ 21011 differed from the “donor” one due to changes in the instrument panel and the addition of a reversing light in the rear of the body.
In addition to the mentioned modification of the VAZ 21011, the automaker released the VAZ 21013 model, and the main difference was:
- 1.2 liter engine;
- suspended gas pedal;
- control of the windshield washer using a foot drive.
For reference: the state advertised the new product in every possible way. This is evidenced by the fact that in videos and films of those years, cars of the VAZ family were seen much more often.
At what interval should you change the DSG7 oil?
Electrical diagrams of VAZ 2109
Given that the manufacturer considers this transmission to be maintenance-free, there are no official recommendations regarding the mileage or period after which new lubrication will be required. In such a situation, it is better to turn to the experience and advice of owners of cars with DSG.
By searching for information on the forums of the owners of these cars, you can find different points of view. Some say there is no need for replacement, since the design uses a dry clutch, others insist on updating the oil almost in parallel with the engine oil. However, most experienced users indicate the need to service the gearbox every 30 or 40 thousand kilometers.
Replacing the front fender
In case of minor damage, without removing the wing, it is straightened and painted. After straightening, be sure to check the condition of the internal anti-corrosion coating; restored if necessary. If the wing is significantly deformed or torn, it is replaced by removing the bumper, hood, antenna, front door, and the lighting fixtures and trim from the wing. Using a drill with a diameter of 6-7 mm, drill out contact welding points of the gutter with body elements over a length of 900 mm and disconnect the gutter from the body with a thin flat chisel with a bent end. Using a thin, sharp chisel, cut down or cut off with a grinding machine along the wing of the joint:
- with the front panel at a length of 208 mm from the headlight downwards (2-3 mm away from the connection line);
- with a front side pillar 580 mm long (5 mm from the bend line of the vertical amplifier);
- with the lower part of the body side vertically 120 mm and horizontally 180 mm (from the edge of the wing 25 mm).
Using a thin chisel, remove the remaining strips of the wing at the joints with the body, straighten the deformed edges and clean the seats of the body elements and the new wing with a grinding machine. Dirt and rust are removed from the cavity closed by the wing and zinc chromate GF-073 is applied. Reinstall the hood and door. They adjust the new wing to the landing site and grab it with grips, maintaining external gaps with the hood and door. The wing is welded by gas welding at the ends of the horizontal amplifier (groove) of the wing, at the junction of the wing with the front panel and the lower side panel. For gas welding, brass rod L62 or L68 is used. Check the position of the wing and the gaps between the wing and the hood and door. The wing is welded by resistance welding in increments of 40-50 mm. In the absence of a resistance welding machine, electric welding in a carbon dioxide environment using Sv-08G1S or Sv-08G2S wire with a diameter of 0.8 mm is allowed.

How are the main wiring elements of the VAZ-2106 car protected?
The electrical wiring of the machine is protected by fuses, which are mainly installed in the central and additional units, located at the bottom of the instrument panel on the left side next to the steering column.
The circuit from the battery to the terminals and connections is closed when the car ignition is turned on. If one of the circuit elements is damaged, the fuse trips. If a malfunction occurs in the main set of fuses, the backup fuses are switched on, which are additionally installed next to the ignition unit. If a blown fuse is detected, it is not enough to just replace it - you need to study the wiring in detail and find out the reason for the combustion of this spare part in the VAZ-2106.
The electrical equipment and wiring diagram should help you quickly find and eliminate faults in the headlights, dashboard indicators and other systems of your VAZ-2106.

Prevention measures
In order for the VAZ 2101 wiring diagram to always work without failures, it is necessary to follow certain preventive measures:
- First of all, use only fuses that match the rating. If the socket is designed for 10 amperes, you cannot install 15A or 20A fuses in it, this will lead to their accelerated failure. There is also no need to install less powerful fuses, unless as an exception, in order to get to the store and buy the necessary part.
- When installing certain devices, as well as repairing wiring, make sure that the wires are laid correctly and do not come into contact with moving parts. Otherwise, this may lead to their rubbing and, accordingly, further damage.
- Do not use the cigarette lighter splitter by connecting many different gadgets to it. The cigarette lighter itself is designed for a certain power, and if you use a splitter with 2 or more sockets, the load on the device increases significantly. Well, if the fuse ends up blowing, you'll need to replace it, but the result could also be a short in the wiring, which could lead to a fire.
Distributor
On VAZ 2101 models until 1980, a distributor (distributor) of the R-125B model was used. Its peculiarity was the absence of a vacuum regulator; there was only a mechanical type octane corrector, which made it possible to slightly change the ignition timing (IZ).
Beginning in 1986, together with the installation of the Ozone carburetor, a distributor equipped with an OZ vacuum regulator (model 30.3706), the design of which is described below, began to be installed on VAZ engines.
Model 30.3706 consists of a distributor, a breaker and two regulators - centrifugal and vacuum.
It consists of a rotating rotor and fixed segments located in a plastic cover. There are two contacts on the rotor - central and side, with an interference suppression resistor attached between them. A graphite electrode is pressed from above to the central contact; for better contact, pressing is carried out by a spring.
The distributor works like this:
the voltage from the secondary winding is supplied to the rotor, then through a spark gap of approximately 0.5 mm it enters one of the segments of the distributor cover, then through high-voltage wires to the spark plug, which ensures the appearance of a spark.
The breaker ensures that the electrical circuit opens at the right time. Its design includes a cam washer with edges and a contact post. The edges of the cam washer are specially shaped to ensure quick opening of the contacts, smooth closing of the contacts and absence of rattling.
The rotating cam alternately closes and opens the contacts, thereby interrupting the voltage supply to the primary circuit of the coil.
The breaker and distributor must work synchronously with the crank mechanism. To ensure synchronization, the cam washer and rotor are located on the same shaft, and are driven by the camshaft.
Centrifugal regulator – provides a change in the angle of rotation in accordance with the rotation of the knees. shaft
A plate with movable weights is welded to the top of the cam bushing. With increasing knee speed. shaft, the weights move apart due to centrifugal force, turning the plate together with the cam in the direction of shaft rotation. This ensures earlier opening of the contacts (increasing the angle of contact).
Vacuum regulator – adjusts the OP angle depending on the load of the power unit and the position of the throttle valve.
It is attached to the distributor and includes a housing and a cover. The body is divided by a plastic membrane into two cavities, one of the cavities is connected to the throttle space in the carburetor, and the second to the atmosphere. The membrane can act on the breaker through traction.
As the load decreases, the filling of the cylinders with the combustible mixture and the pressure during ignition decreases, and this requires an increase in the angle of ignition. To do this, the membrane bends (under the influence of a pressure difference) and rotates the breaker to the desired angle.
Reasons for bearing failure
It is worth noting the reasons why the bearing on a VAZ-2110 wears out. These include:
- lack or leakage of lubricant;
- a rough surface (abrasive) forms in the bearing, which causes creaking;
- end of operational life;
- wear of VAZ-2110 bearing parts;
- belt failure;
- complete rotation of the pulley.
After diagnosing and identifying the causes, it is necessary to replace the bearings of the VAZ-2110 generator. The whole process will be divided into several stages. First of all, you have to remove and disassemble the mechanism, then dismantle the old and worn parts, and only after that install new ones and reassemble the generator. The very last step is to launch and check the functionality of the entire mechanism.
It is important to remember that all of the above should be done with special tools, such as:
- keys of different sizes (7, 8, 10, 13 and 27);
- Phillips and flathead screwdrivers;
- hammer;
- vice;
- pliers,
- puller;
- anti-corrosion liquid WD-40.
