DIY VAZ 2106 turn signal repair

In detail: do-it-yourself repair of the VAZ 2106 turn signal relay from a real master for the site my.housecope.com.

Such an element of electrical equipment of the "six", as the VAZ 2106 turn signal relay, is designed to signal pedestrians and vehicles that this car is going to move along a different trajectory (to make a turn in one direction or another).

The standard VAZ 2106 direction indicator relay, the price of which is an insignificant amount and is quite affordable for any Russian motorist, is a mandatory means of warning about a change in traffic for a vehicle due to the signal system adopted among motorists and is located under the dashboard in the driver's seat area. Directly the electrical circuit of the "six" turns relay and its position in the vehicle electrical system is located below

and the numbering in the figure is deciphered as follows:

Sidelights "six".
Side direction indicators.
Battery.
Generating device.
Egnition lock.
A block device for the concentration of safety elements that protect all electrical circuits of the vehicle's power equipment.
Relay for direction indicators VAZ 2106 and alarm type, operating in intermittent mode.
A corner signaling lamp located in the speed sensor (speedometer).
Button for stopping the flashing of the emergency gang.
Stern optics.
Rotation switching element in the switch is a three-position type.

The necessary replacement of the VAZ 2106 turns relay begins with the preparation of the workplace for such a technological operation. This requires:

This replacement of the turn relay is made due to the frequent failure of the standard product. During the operation of the standard turn signal relay, there comes a moment when it periodically starts to work incorrectly. This can be seen by the lack of ignition of the "control". The reason is in the absence of a complete closure of the product. The lack of sound accompaniment of the turn maneuver creates the illusion that the turn signal relay is faulty.

Otherwise, the malfunction of the product manifests itself in an unstable period of the product's functionality. This is due to the time interval of closing the relay contacts. The next thing is that the standard turn signal relay works with a low volume level, which creates a problem if it is unauthorizedly turned on if it accidentally touches the driving process.

The above disadvantages can be eliminated by replacing the turn relay from a standard one to an electronic sample. The pinout of the electronic type relay is presented below.

Positive contact.
Output contact to the turn signal switch.
"Control".
"Weight".

It must be remembered that good insulation of the contacts is required, and this must be done with insulating tape and a cambric (hollow plastic braid). This is necessary to exclude possible short circuits with other wiring. Another feature is the fact that the VAZ 2106 electronic type direction indicator relay is integrated into a plastic case and its linear dimensions do not make it possible to install it in a regular position. In addition, the presence of an additional "petal" also interferes with the installation process.

An independent solution is needed in order to connect the turn relay of a new sample. We propose as an alternative to apply the so-called. "Strip" - a plastic-type clamping clamp for fastening electrical wiring. Such a mount seems to be quite long-term and reliable.

To install an emergency gang on a VAZ 2101 with our own hands, we need: an emergency gang button from a six and a chip for it, a six turn relay, a six-pin chip for a turn relay.

Here is the diagram for turning on the turns of the VAZ 2101:

1 - sidelights;
2 - side direction indicators;
3 - storage battery;
4 - generator;
5 - ignition switch;
6 - fuse box;
7 - relay-interrupter of direction indicators;
8 - indicator lamp for direction indicators;
9 - turn signal switch;
10 - rear lights

And this is the diagram for turning on the turns and alarms for the VAZ-2106:

1 - sidelights; 2 - side direction indicators; 3 - storage battery; 4 - generator; 5 - ignition switch; 6 - main fuse box; 7 - additional fuse box; 8 - relay-interrupter for alarm and direction indicators; 9 - control lamp of direction indicators in the speedometer; 10 - alarm switch; 11 - rear lights; 12 - direction indicator switch in a three-lever switch.

And this is a diagram for connecting a VAZ-2106 turn relay (view of the contacts):

We connect in the following sequence:

1. Disconnect the old turn relay (barrel) and connect the blue wire to pin 3 of the new relay, this is the control on the dashboard.

2. We connect a piece of wire to the 4 output of the new relay; when attaching the new relay, we screw it to the ground.

3. White and black wire (sometimes purple) is connected to the 2nd output of the relay and to the 7th output of the emergency gang button (the numbers on the button are written on the back).

4. Add the orange wire (ignition) and connect it to pin # 2 of the button.

5. 1 output of the turn signal relay is connected to output No. 4 of the emergency gang button.

6. At the 8th output of the button we supply constant power, for example, from the first fuse.

7. Connect 1 output of the button to the blue wire in the tube chip.

8. Connect the third pin of the button to the blue one with a black stripe in the tube chip.

There is another option. On the market, ready-made wiring for connecting the alarm is sold:

Installation of an emergency gang on a VAZ 2101:
Red - to white with a black stripe (or purple), this is the load.
Yellow - to blue (this is control).
Blue to orange (ignition).
Brown with a red stripe is a permanent plus (for example, on the first fuse).
White and brown with a white stripe to the tube counter (left and right turns).

We fix the turn relay in place of the old one, not forgetting about the masses. Cut out a round hole for the emergency gang button (the washer pump hole is ideal, but not on all models). If you have a desire to somehow transform the car, I advise you to install the front windows from the VAZ 2107 with your own hands, it looks just super!

With such a colossally high rhythm of movement, the behavior of each individual motorist in the stream of cars should be as predictable and understandable to the rest as possible. It is important here not only the ability to drive a car, give the necessary signals in time, but also the technical serviceability of the light signaling systems. This is especially felt when driving old-style cars, for example, on a VAZ 2106, the direction indicators, the low and high beam of which work with the help of a relay. This technique has long been discontinued, it is potentially problematic, which means that its owner is simply obliged to know the device and methods of repairing the systems of his car.

If we turn to the Road Traffic Regulations (SDA) in force on the territory of the Russian Federation, then there are clear formulations regarding maneuvering. Before starting a movement, changing lanes, changing direction, stopping, the driver of the VAZ 2106 must use the direction indicators, and if they fail, give a signal with his hands. In conditions of poor visibility, you will also have to use low-beam sources, and to increase the information content of the dialogue between the participants in the movement - also distant.

The lights on are usually enough to make the car visible on the road, but no more.If you need to draw the attention of other road users to a specific detail, action, lighting should not be static, but dynamic - flashing. To put this principle into practice, you need to understand that both headlights and indicators are part of a single electrical circuit of the "six". In order for the pointers to blink, a periodic break in the lamp power supply circuit is required, and this is where a special remote key or relay is needed.

In the “six”, most of the relay breakers are located in a compact, single unit in the power compartment. At the same time, the electronic key for the turn signals, as well as the emergency light, are located inside the passenger compartment under the dashboard. Externally and technically, they are of the same type, that is, there should be no problems with interchangeability. The main objectives of these circuit components are:

current supply of lighting lamps and direction indicators;
periodic interruption of the circuit, creating the effect of flashing lights;
sound signal in the form of characteristic clicks accompanying interruption and flashing.

The implementation of all the necessary functions is possible thanks to the device of the relay itself, which has two groups of contacts. Some are stationary, while others are mobile, connected to the armature, and through it to the electromagnetic coil. When the latter attracts the contacts, they are struck against the armature, causing characteristic clicks.

Malfunctions in the operation of the turn signal relay or the low / high beam in the VAZ 2106 happen quite rarely. These mechanisms are quite reliable, but, being part of the general electrical circuit of the car, they are not insured against problems such as overvoltage, breakdown, etc. In fact, the products are not repairable - it is practically impossible to eliminate damage to the coil or contacts qualitatively. In other words, when a defect or malfunction is detected, the mechanisms are simply changed to similar ones, selecting them according to the catalog number:

for the turn interrupter relay - 231.3747-10 (11) or 23.3747-10 (11);
for the lighting interrupter relay - 113.3747-10 (11) or 90.3747-10 (11).

The number at the end of the designation indicates the design of the device body: the 10th modification is equipped with a mounting flange, and in the 11th it is absent, which is compensated by the increased dimensions of the body. Also, when choosing electronic relay-interrupters, it should be remembered that rotary models are compatible with relay alarm units, and lighting models are compatible with devices for switching on the fan motor, horn, plate heater of the rear window. A malfunction of the relay unit may be indicated by problems in the operation of the lamps controlled by it due to the impossibility of closing the circuit or, conversely, opening it.

Rotary relays may indicate a problem with too fast or slow flashing and no clicking sound. But the rapid blinking of the control light on the dashboard indicates a burnout of the lamp in the headlight, and not the relay itself.Since the direction indicator relays on the VAZ 2106 are located under the dashboard, the first step in the process of replacing them is to dismantle it. To do this, the panel clamps are squeezed out, and then the latches along the contour. The block is pulled out into the cabin.The turn signal relay box is screwed to the engine compartment housing with a nut. To dismantle it, you will first have to unscrew it using a 10 socket wrench. The nut is pressed against the terminals of the two "ground" wires, which it is desirable to mark in order to avoid confusion in the future. The removed relay block is disconnected from the terminal block, after which the assembly process is carried out in the reverse order: connection with the block of the new block, and then with "ground" wires, screwing to the case and installing the dashboard.The relay keys for the headlights are located in the engine compartment itself, on the right mudguard. First you have to dismantle them by unscrewing the mounting screws. It should be noted that under the mounting bracket of the unit attached to the main beam, there is one more ground wire contact.After dismantling the light relay unit, the power wires are disconnected. However, it is highly recommended to label them so as not to be confused during the reassembly process. You can do without this operation by immediately connecting the disconnected contacts to the new relay unit. After that, the mechanisms are installed and fastened into place.

Movement change signal

Cars began to be equipped with direction indicators, which had to pulsate to attract attention. So that the devices did not shine constantly, but periodically blinked, a small device was invented, which later became known as a pointer interrupter or a rotary relay.Despite the rather large presence of varieties of the mentioned device, their functions are similar: giving a pulsating pulse to the turn signal lamps and signaling with clicks that they are on.

Modern rotary relays are mainly classified into two types: thermoelectric and electronic... Each device has its own advantages and disadvantages, and this is what will be discussed. Thermoelectromagnetic relays are based on a core with two contact groups and side armatures. In addition, they are wound with copper wire. The contacts leading to the light bulbs are connected to a thin nichrome wire, which, in turn, is connected to a plate that closes to the core.In the normal state, when no current flows into the circuit, the plate does not adjoin its base. As the electrons begin to move, the nichrome wire heats up, lengthens, and closes the cored plate. The lights come on. After that, the nichrome cools down, the plate leaves again, the current changes direction, and the bulbs burn at full speed. Since the cooling-heating process occurs rather quickly, 1-2 times per second, the turn signals are blinking. Since the light located on the instrument panel is also connected to the circuit, it also begins to pulsate. The specific clicking of the breaker is a consequence of the cyclic impacts of the anchors on the contacts. Image - DIY VAZ 2106 turn signal repair

Auto turn signals flashing

A relay of this type has been installed on all cars for quite a long time, but it had (and has) a significant drawback. Over time, the nichrome wire pulls out and the direction indicators no longer work. Besides this, there is another point. If one of the bulbs burns out, the load on the others increases significantly. In recent years, thermoelectric relays have practically not been installed on cars. They have been replaced by more reliable electronic circuit breakers.

Electronic relays for direction indicators are built on the same principle as thermal relays, but instead of a wire made of nichrome, an electronic circuit of transistors operates here. An algorithm is incorporated into the control microcircuit, due to which automatic pulses are produced, at certain moments supplying current to the core winding. The operation of the device itself is as follows: after the voltage is applied to the transistors, frequency pulses come from them, having those oscillations that are set by the program in the microcircuit. Passing through the circuit, the current attracts the armature, closing the contacts leading to the lighting fixtures, as a result of which the bulbs light up. Since the cycle consists of signals of different frequency, they either work in full heat, then dim.

Electronic relay for direction indicators

The advantage of electronic breakers is that they are more reliable than thermal breakers. In addition, if one of the bulbs burns out in the circuit, the others work further without unnecessary load. True, in some cars the circuit is arranged so that in this case the control lamp on the instrument panel stops flashing. This is done on purpose in order to additionally signal a malfunction. True, there are also disadvantages here. First of all, such a relay creates radio interference and can affect the operation of many devices. The second negative factor is that the short circuit protection is very weak here, and at the slightest voltage drop, the breaker can easily burn out.

No matter how reliable the devices responsible for control lighting devices are, they are also devoid of perfection. Malfunctions still happen, and under some circumstances, the consequences will be disappointing. Therefore, one must be very careful about the slightest breakdown, especially related to external alarm devices. Image - DIY VAZ 2106 turn signal repair

Malfunction of the lighting control device

You can find out about the failure by the characteristic features: as already mentioned, this is a constantly burning warning lamp on the instrument panel, the absence of characteristic clicks when the turn signals are turned on.The algorithm of actions is known to any driver: first, the fuses are checked, then the presence of current in the circuit, and, finally, the relay itself is checked. The latest trend in the automotive industry is the turn signals integrated into the side mirrors.

Although they perform a duplicate role, they serve as an addition to other direction indicators, but their "silence" is also quite unpleasant. In the rare event that the lights are off, you should also check the circuit, making sure the wires to the mirrors are not frayed. Even motorists familiar with electronics do not undertake to repair this device. The breaker is not that expensive, and therefore replacing it will be the most acceptable action in the event of a failure.

Recently, LED lamps have begun to be used on many cars as lighting elements in turn signals. Attempts by our "craftsmen" to simply change them for light bulbs do not lead to anything. Many people have absolutely no idea how the relay itself functions, and have absolutely no idea that it needs a little additional work. Image - DIY VAZ 2106 turn signal repair

Modification of the direction indicator relay

Anyone who is familiar with radio electronics and has experience in assembling radio devices knows what to do - you need to solder a small electronic board into the breaker, the circuit of which is available on the World Wide Web. If you do not have the skills to communicate with semiconductors, then if you have a desire to use LEDs instead of ordinary bulbs, it is best to contact an automotive service specialist.

The relay is designed to inform pedestrians and other drivers about a change in movement, or a car maneuver. Depending on the modification of the car, it is located in the engine compartment of the car, or under the dashboard in the passenger compartment.Direction indicator malfunctions - symptoms

The absence of flickering is one of the clear and frequent signs of a device failure.

No disconnection when turning the steering wheel.

Very frequent blinking (often the reason may be a burned out lamp, or the lamp power does not correspond to the nameplate)

An annoying click.

Dim turning indicator.

On, but not flashing.

Sticking.

The alarm button is defective.

To eliminate the causes of the malfunction of the turn signals, it is necessary to check and, if necessary, replace the VAZ turn signal relay.There are two types of location of turn signals in the classic family of VAZ cars, depending on the modification:

Hood space - an electromagnetic relay is installed, or an electronic one. It is used for models of cars of the VAZ 2101-2103 family inclusive.

Dashboard - the device is connected using a semiconductor electronic circuit. This arrangement is typical for VAZ cars of a later family.

Let's start disassembling

Early modification models

To get to the relay, you need to remove the plug by unscrewing the bolt on the dashboard.

We pull the entire panel towards ourselves, move the sensor shield slightly to the side so that you can get to the relay.

The contacts go to the relay from below.
We disconnect the contacts.
We remove the old device and install the new one.
We put back the dashboard, leading it into the side grooves.
We screw in the bolt.

We check the turn signals for flickering and characteristic clicks. The frequency of contact closure should be approximately 1 time per second.

The technology is very simple. The main difficulty here is accessibility to the relay.The space under the panel of these models is small, and getting there is problematic.

Later models

Remove the steering column switch cover screws. We release from the casing elements.
Unscrew the mounting bolt.
We take out the devices on the wiring inside the cabin.
We replace the old relay with a new one.
We screw it back. We put the covers in place.

Replacing the relay in the engine compartment

We open the hood. We squeeze the latch of the mounting block cover.
The part can be removed in one simple motion.
We remove the relay. And we put on a new one.

Important: the relay itself or the mounting block is recommended to be replaced as an assembly, given that the wiring often burns out, and it is quite problematic to restore the contacts.

When replacing any of the above relays, special attention should be paid to the isolation of the contacts. Insulation is carried out using a hollow mass braid. Use a special strip clamp to tie the wires.

Here is such a "barrel" is located under the dashboard of the car. This is an electromagnetic thermal relay. Due to the short-term operation (1-2 months), it is recommended to replace it with an electronic one. After this time, it starts to burn, or it closes.

The following are the steps for replacing it:

disconnect the contact terminals;
we designate each wire with a marker, or use paint for highlighting in different colors;
contact No. 1 of the electronic relay is connected to the wire with the x sign;
contact No. 2 of the electronic relay is connected to the wire with the L sign;
contact No. 3 of the electronic relay is connected to the wire with the P sign;
contact number 4 is a mass, we bring it to a separate wire.

All these works must be carried out when using heat shrinkage.

Replacement of incandescent lamps in direction indicators with LEDs is gaining great popularity due to the fact that incandescent lamps are much inferior to LED lamps in terms of service life and luminous efficiency.

A good channel, it is pleasant to listen to and you take a lot of useful things for yourself, a very understandable explanation. Image - DIY VAZ 2106 turn signal repair

Thank you for such an assessment of my work. It is very important for me.

everything is clear and accessible. (like unambiguously) but I had to set 2x rewind too slowly ..

hello. I want to install turn signals on my moto block. but something doesn’t blink. connect the relay as you connected in the video. but didn’t get a new relay bought from the store. and I took the current from the walk-behind tractor itself and not the battery. what could be the reason ?

super as always. health success! more money

Valery tell me how to solder a resistor in the VAZ 21074 turn relay for diode bulbs there are three legs on the resistor and which ones to solder

I assembled such a scheme, it turned out the opposite, where you have a plus on one, then I have a minus, and where plus, then I have a minus. The relay only pulls in but does not click and only one light bulb works, the result is zero. What is the reason?

Good day to Valeria.
The problem is this. relyushka vaz 2107 electronic it works then no. knock on relukhi works. then the 4-pin Relushka does not work again.

Hello. Although it is electronic, there is a conventional electromagnetic relay at the output. In addition, it is not a fact that when you knock on it, something changes inside the relay, it may also be a bad contact outside. Open carefully, carefully inspect, you may see a defect, turn on the relay without a cover, observe what interferes with normal operation. This is the logic of actions. Good luck.

Hello Valery. On my vaz2105, when the ignition key is turned on, the turn signal indicator on the display lights up. When the turn signals are turned on, the voltmeter arrow falls through. And when the emergency light is turned on, the arrow behaves normally. I pull out the emergency gang button, the turn signal indicator goes out. Please help me.

Hello. Under the dashboard, if you look from the side of the clutch pedal, you can see a block that is stuck in the turn signal relay. This relay is fixed in the same place where the ground contact of the instrument panel is attached. Turn on the ignition and shake this relay, if there are changes, then tighten the fastening nut. It would be nice to splash WD-40 in there.

very informative and intelligible.
but, here's the question, that is: what if a specific magic happens, and the lamp on the alarm button itself works in unison with the control lamp on the instrument panel, and the entire circuit of the car's lamps. in other words, the control on the emergency gang button works the other way around.
how to understand schematically why this is happening?

As I understand it, there is probably the only option: to bite off in the button itself the track that is responsible for the lamp in the button, and connect it separately with the control from the instrument panel?
or is there another way out?

Sorry, I really put it wrong: the lamp on the emergency gang button works in resonance with the main on-board line of turns and controls on the dashboard. now, now I put it right)))

In unison, as far as I remember, it means in one rhythm. Second, why are these alterations. The main thing is that all lamps are working and the number of flashes per second is normal.

Good afternoon. Tell me the VAZ 21074 periodically happens that the relay starts to click and the light on the dashboard starts flashing, the direction indicators do not blink the direction indicator switch in the neutral position, the bulbs are not burned out. I changed the breaker relay, it repeats again. Tell me how to fix it? Periodically arises and disappears. Thanks for the detailed answer.

Hello Valery! I have a niva 81 years old. I was engaged in tuning - I replaced the bulbs with LEDs and now, when the turns are turned on, there is no blinking at all, then it appears slowly, when the emergency lights are turned on, there is also no blinking

Hello, do not tell me to change the 4-pin to 3x adjustable for the VAZ 2106, but the lamp on the instrument panel will go to ground, that is, when the emergency gang is turned on.

Everything is great! Thank you very much.

Hello! I bought a 4-pin relay without checking which one is in the recently acquired 6k, but it has a 5-pin one. You said that you can connect the 1st and 5th contacts with a jumper, but in my car, wires of different colors are suitable for the 1st and 5th contacts. What to do with the fifth?
If I want to remake it for a 4-pin relay.

Can I put four instead of a five-pin relay? Where then to put the fifth extra brown wire?

Hello Valery, I have a VAZ 2104 when the ignition is on and the headlights are turned on, the direction indicator light on the dashboards starts blinking quickly, where to look for the problem?

thanks for the review! just today I found “SOMETHING” in the garage - I don’t know. I see what the relay is, but from what and for what I do not know. Here I sketched the data from it into a line and YOU HERE HERE HERE! THANK YOU!.

Tell me whether or not you can burn the three-stroke relay of turns if the minus and plus are mixed up?

Hello Valery! A question for you! The turns do not work when you turn on and also the alarm button when you press it! Previously, this phenomenon passed by itself, but now it appears again! What can it be and how to fix it? VAZ 21074 car. Also periodically the central locking on the front passenger door does not bounce, it works on the right, tell me how to fix it?
Thanks in advance.

Hello. Please tell me I did everything like you have in the video option 2. The end result is they both burn. Question: they are blinking for you and they are continuously on for me, what does this mean? Is my relay working or not?

Hello . If this relay on the car shows the same result, then it is not working properly.

help to solve the problem when the ignition is turned on, the indicator lamp for the turn signals on the dashboard is dimly lit. with all this, because of this, the battery sits down to zero. And the fuse burned out 9 changed And again burned out.

Video (click to play).

At one time, such transistor turn relays were in great scarcity. I myself did it on the basis of the burnt ones. Fortunately, there was a diagram of such relays. The first relay I made for the Minsk motorcycle when I was 24 years old. The first models of those bikes came without cornering lights. So then I made all the lights and relays myself for him. I am also an electronics engineer. At first it was my hobby, then since 1991 it has become a profession.He could also fix wristwatches. Even women. TV sets, power tools. Even the umbrellas had to be repaired. Not to mention such electric kettles with a heating function. The last kettle I repaired three years ago is still working at work. It had to make an element for heating boiled water. And how many modern electric kettles I repaired, I lost count.
