The VAZ 2114 (Samara-2) car is built on the VAZ 21093 platform and is an improved version of the car. The first prototype of the hatchback was assembled back in 2000. A year later, the Volzhsky Automobile Plant produced the first pilot production batch of 50 cars, and in the same 2001, the hatchback was first introduced to the market. The interior received a new instrument panel, a new steering wheel, an adjustable steering column, power windows and a new heater, which naturally affected the electrical circuit of the VAZ 2114.
The fourteenth model was previously equipped with a 1.5 liter eight-valve engine, borrowed from the VAZ 2111 model with an injector. A little later it was replaced by the VAZ 11183-1000 version, which complies with the Euro-3 standard. The VAZ 2114 injector received a more powerful motor, and this is one of the reasons that the wiring of the 2114 has also changed.
A wiring harness has been added for connecting to the electronic switch. A harness has also appeared for connecting to the ignition module terminal.
Replacing high-voltage wires will require additional attention, because the connection procedure depends on the year of manufacture of the car. Until 2004, 4-pin ignition modules were installed, and after that - 3-pin. Connecting the adsorber valve to the injection system controller also provided another additional element. An adsorber is an electromechanical device used for ventilation and removal of condensate in a gas tank. Complications also affected the interior part. The dashboard received improvements in the form of the appearance of a BC (on-board computer), a new instrument panel and a change in the position of the glove compartment.

Possible causes of signal failure
1) Fuse blown
A voltage surge in the vehicle's on-board network can damage any electronic element, therefore, to avoid such a problem, fuses are provided, incl. and on the sound element. A blown fuse is a common situation, so when attempting to carry out repairs on your own, you should first check its condition. The fuse responsible for the sound supply in the VAZ 2114 is located in the mounting block. You can study the exact location of the element in the diagram below of the new sample mounting block. The fuse for monitoring and turning on the sound signal in the new type mounting block is designated by the combination F5 and is located in the left column of fuses (fifth in a row). The fuse current installed in the block socket should be 20 Amperes. Almost any car store or gas station sells kits, including 20 Ampere fuses.
Important! To conveniently replace a burnt-out element, use a special paperclip, which comes in a package with other fuses. Such a clip is located in all car mounting blocks from the factory, but over time most car enthusiasts lose it.
2) Failure of the electrical relay
The second most common problem is the burnout of the main relay, which is responsible for the operation of the car’s horn. This relay is located in the same mounting block along with the fuses. Unlike fuses, relays can be replaced without using a paperclip. The diagram below shows the relay responsible for the signal. To select a new relay, just visit any spare parts store for domestic cars, where they will provide you with a suitable relay. For self-checking, you can replace the failed switching device with an adjacent heated rear window relay, marked in the diagram with the combination K7.
3) Signal button failure
In addition to electrical elements, the circuit of the entire signal structure also contains mechanical parts, which over time can break or completely wear out. A button is just one such element. In the design of the VAZ 2114, this button is a plate that, when the steering pad is pressed, closes and voltage is sent to the signal itself under the hood. Periodically checking these elements for contamination can save you from sticking of the plates and their premature wear. It is worth noting that the steering pad on the VAZ 2114 can be removed quite easily using a Phillips screwdriver.
4) Wear of the slip ring
The problem due to slip ring wear occurs on cars with high mileage, or on cars where low-quality structural parts were installed. The photo below shows two slip rings, one of which is worn out. Even from the photograph you can see that the ring on the left has a large hole, due to which the sound supply may work every once in a while or not work at all. This problem is solved by replacing the ring with a new one.
5) Oxidation of contacts on the steering wheel
Moisture getting into the steering wheel housing or the age of the car are the two main reasons why the contacts on the steering wheel become oxidized. Poor contact at the junction of the wires and the plate may cause the signal to fail. To solve the problem, remove the steering wheel pad and the top plate, then clean the wires from oxides. Lubricants can also be used to seal out moisture.
6) Horn failure
Failure due to wear or sticking of the membrane is rare, but still possible. The design of the VAZ 2114 signal itself is quite reliable, but it also periodically fails. This “snail” is located right under the hood near the car’s radiator. Sometimes, to “unstick” the membrane, it is enough to hit the body. If this does not help, you can always disassemble the case and clean the mechanism. As a last resort, you can buy a new “snail”, since its cost is 300-400 rubles.
7) Broken wiring
The last reason for a possible failure of the mechanism is a broken wiring. Often this problem occurs after work has been carried out to install an alarm system, additional devices or other implementation into the standard wiring of the machine. Wiring rotting is also a common situation. The problem is solved by completely replacing the wiring of the electrical circuit. In general, almost any reason for a non-working signal from the list above can be eliminated quite easily (and on your own), so you should not worry and look for all the design elements in the store.
Detailed color diagrams of the VAZ 2114 wiring (carburetor, injector) are provided with a description of the electrical equipment for various modifications. The information is intended for self-repair of cars. Many electrical circuits are divided into several sections for ease of viewing via a computer or smartphone; there are also circuits in the form of one picture with a description of the elements - for printing on a printer.
The VAZ 2114 (Samara-2) car is built on the VAZ 21093 platform and is an improved version of it. The first prototype of the hatchback was assembled back in 2000. A year later, the Volzhsky Automobile Plant produced the first pilot batch of 50 VAZ-2114 cars, and in the same 2001 the hatchback was first introduced to the market. The interior features a new instrument panel, a new steering wheel, an adjustable steering column, power windows and a new heater. Years of production 2114: 2001—2013
The fourteenth model was previously equipped with a 1.5 liter eight-valve engine, borrowed from the VAZ 2111 model with an injector. A little later it was replaced by the VAZ 11183-1000 version, which complies with the Euro-3 standard. The VAZ 2114 injector received a more powerful engine, and this is one of the reasons that the wiring of the 2114 has also changed.
A wiring harness has been added for connecting to the electronic switch. A harness has also appeared for connecting to the ignition module terminal.
Replacing high-voltage wires will require additional attention, because the connection procedure depends on the year of manufacture of the car. Until 2004, 4-pin ignition modules were installed, and after that - 3-pin. Connecting the adsorber valve to the injection system controller also provided another additional element. An adsorber is an electromechanical device used for ventilation and removal of condensate in a gas tank. Complications also affected the interior part. The dashboard received improvements in the form of the appearance of a BC (on-board computer), a new instrument panel and a change in the position of the glove compartment.

| 2 | generator VAZ 2114 model 94.3701 |
| 3 | fuse box |
| 4 | battery charge indicator lamp located in the instrument cluster |
| 5 | egnition lock |
The current to excite the generator when the ignition is connected is supplied to terminal “D+” of the regulator (terminal “D” of the generator) through signal light 4 installed in the instrument cluster. After starting the motor, the excitation winding is powered by three additional diodes mounted on the generator rectifier block. The operation of the generator is monitored by a warning light on the dashboard. When the ignition is connected, the light should be on, and after starting the engine, it should go out when the generator is working. A bright glow of the light bulb or its burning at half intensity indicates a malfunction of the generator.

| 7 | source of electricity |
After running the generator on the stand for 10 minutes, with the rotor rotating at a speed of 6000 rpm, the output current of a working generator brand 94.3701 should be at least 80 A.
Diagram for testing additional generator diodes 94.3701
The short circuit of the additional diodes of the generator 94.3701 can be checked on the car, without removing the generator from it, according to the diagram below. In this case, you need to disconnect the wires from the battery and generator, remove the protective casing of the generator and disconnect the wire from the “D+” contact of the voltage regulator.
If the light is on, then there is a short circuit in one of the additional diodes. A break in additional diodes can be determined by the low voltage at contact “D” at an average rotation speed of the generator armature.
Generator rectifier valve test diagram 94.3701
A working valve allows electricity to flow only in one direction, but a broken valve does not allow electricity to pass through (open circuit), or allows current to flow in both directions (short circuit).
When the light is on, when checking according to diagram “I”, the “negative” and “positive” valves have a short circuit. When checking the valves according to scheme “II”, the light on the lamp indicates a short circuit of one or more positive valves. The glow of the light bulb, when checking the valves according to scheme “III”, means a short circuit in 1 or several “negative” valves. You should be aware that in this case the glow of the light bulb may also be a consequence of the short circuit of the stator winding turns to the generator housing. However, such a breakdown is much less common than valve short circuits.

Operating principle
A fan is a device that allows you to increase the efficiency of a cooling radiator. The radiator takes heat from the engine and releases it into the air. This process is accelerated by blowing through the blades of an electric fan.
The coolant flows through a closed, sealed system. Its task is to remove excess heat from overheated engine parts. Hot antifreeze flows into the radiator, is cooled here and returns back. While in the radiator, the coolant passes through a system of thin tubes. The incoming air flow while the car is moving helps to quickly remove excess heat from the engine compartment.
But when the car is stuck in traffic or idling, the air flow stops cooling it. In this case, the cooling system may not cope with its task. An electric radiator fan is designed to create air flow artificially. The temperature for turning on the fan on a VAZ 2114 is 85 degrees Celsius.
Having received a signal that the permissible temperature value has been exceeded, the sensor starts the device’s operating mechanism. An artificial air flow is created that removes heat from the radiator. The mechanism operates until the temperature level drops to an optimal state.
The thermal switch then receives a signal that the normal temperature has been reached and turns off the fan.
The device consists of four plastic blades that are mounted on the EDF shaft. A special controller regulates the automatic operating mode. The thermostat is equipped with a solid filler that is sensitive to temperature changes.
There are main and additional valves. When the temperature reaches 85 degrees Celsius, the main valve opens.
Replacement and repair of VAZ sound signal
The most common reason for the absence of a sound signal lies in the signals themselves. The reason is mechanical, moisture and oxidation lead to blocking of the sound membrane and, as a result, the absence of vibrations and sound effect. Sometimes you can restore functionality by spraying the signal with WD-40 or a similar composition.
On cars, where two signals are installed, as a rule, they are of different tones, low and high. If one signal fails, the second will not be able to fully provide the required power, and therefore requires replacement. As a rule, many signals are equipped with a tone adjustment screw, and if there are wheezing, grinding and other unwanted sound effects, you can use the adjustment to achieve a suitable sound. Also, with their help, you can move the “soured” membrane, thereby restoring the functionality of the signal.
