VAZ 2114 does not work the rear right turn signal. Turn signals and accidents are not working: the causes, diagnosis and what to do. How to check the operation of light instruments with their own hands

The traffic rules prescribe a special way to warn about maneuvers, which must be used if the lamps of the rotation indicators stopped burning on the way. Consider why turn signals do not work and how to eliminate the cause of the breakdown. It will be about the device, the principle of operation and malfunctions of systems using turn signals based on integrated circuits. Old structures with bimetallic plates, as well as completely electronic systems, in view of their specifics and a little prevalence, we will not consider.

If only the front left or rear right turn signal on the car does not burn, the reason may be in a blown light bulb, poor contact "mass" of lanterns or a wire of the wire to the light bulb.

Causes of turning indicators fault

• Fuse blocked. If emergency alarm has ceased to work with the turn signals, the likelihood is great that the cause is in the melting insert.

Instead of the burnt fuse, it is necessary to install only the insertion of the corresponding nominal value. Exceeding the recommended value, the installation of "beetles" can lead to the fire of the vehicle. Therefore, we advise you to observe!

• The failure of the steering wheel switch.
• Breakdown relay turn signals.
• Fault of the alarm button.
• Open electrical circuit. If the turn signals do not work from all sides, the first thing should be checked the power supply wires of the turn signals. If the pointers stopped working only on the one hand, the problem in the wires coming from the steering wheel switch to the light bulbs.
• Oxidized contacts, broken wires. Turning does not work if the chain resistance is significantly different from the nominal. For power supply, you need to exceed a certain power level of consumers. If the chip inside the planet relays due to increased resistance does not register sufficient current strength, the power on the light bulbs will not be applied.

Device

In the work of turn signals participate:

• steel rotor switch. Its function in the closure of the supply contact light bulbs. For example, when turning the switch up, a closure of one of the contacts of the light bulbs occurs right side on "+" acb. "Minus" the bulbs is the connection point to "mass" (the total point for all light bulbs block headlights);
• plannel relays. Inside the case there is a conventional electromagnetic relay, but it is controlled by a microchip. It is thanks to this element that an intermittent power supply to the coil is ensured. The second important function is to control the health of the lamps. The microcircuit has a feedback function, so when the bulb is blown out, it registers the reduction in the power of consumers and begins to feed the power to the coil with a twin frequency. If the turn signals work properly, the light bulbs blink about 1 time per second. On most modern cars, including VAZ models, a 3-pin rotor pointer relay is used. Accordingly, 1 contact is "Mass", 2 - powered by AKB, 3 - exit to the subwoofer switch;
• light indication on dashboard. One or two light bulbs (one on each of the sides) are connected parallel to the electrical circuit of the main lamps. Turn signals will work without light indication, so among possible causes Faults to consider the system is not worth it.

Inclusion scheme

The simplest scheme for connecting signal signals.

On video details the principle of inclusion of turning pointers, as well as the role of the emergency buttons in the system performance.

We are looking for a breakdown with your own hands

The primary diagnostics can be conducted by a control light, but the tester will need to check the condition of the chain. If you know, in the measurement mode, you can ring the wiring on the subject of the break.

The search for the causes, due to which turn signals and accidents stopped working, should begin with the study of electrical stamps. We recommend to refrain from independent repairIf you are unfamiliar to the foundations of electrical engineering, posting restoration methods.

If, when you turn on the right / left turn signal, you clearly hear the clickens of the relay, check the resistance of the circuit area with a steering wheel switch. If only the left or right side does not work, the reason exactly in the switch or in the wiring of the chain from it to the light bulbs.

If the rotor pointer relay does not click at all, check the condition of the contacts, the plus wire and mass. If after switching on the ignition to the relay does not come "+", the problem is most likely in the chain area from mounting block To relay.

Understeering's shifter

The cause of the malfunction can be both in mechanical damage to plastic or contact elements and in the formation of Nagara. During the operation of turn signals, the contacts can be burned, which increases the resistance and the current of the current in the chain falls. At the same time, it is characteristic that in the case of oxides, the ingirts relay can click, but the lamps will not light up.

For repair, the subwoofer will need to be removed from the steering column and disassemble. Inside the case there is a variety of contact pads, so for trouble-free assembly, remember the location of all moving elements.

Where is and how to check the rotary relays

The rotor pointer relay is located in the installation block of fuses in the cabin or under the hood. Contract location you can learn from the repair and operation of your car. Often S. inner The mounting unit graphically depicts the purpose of the relay, fuses.

Saving elements from the scheme, microcracks in placing places, failure of the main chip - the most common causes of malfunction of turning signs.

Avoidance

The emergency button simulates a steering wheel switch, but both contacts are closed at once (on the right and left side). The video shows the device and the principle of operation. simplest systemThe analogues of which are used not only on VAZ cars.

Car owners sometimes concerns such a problem as faulty turn signals, but not everyone knows how to solve this problem is promptly and efficiently. Accordingly, in the case of such a breakdown, the continuation of the movement, especially in the urban stream, will be extremely dangerous. The most rational option will stop and eliminate this malfunction.

Turns of turn signals and methods to eliminate them

The rotation pointer operates correctly only if the following indicators are followed:

- turn signals are always in operation when the ignition is enabled;

When switching a stealing lever, either down should turn on the turn signal with the appropriate side;

A signal that warns drivers about the rotation flashes with a clock frequency of 60 signals per minute.

If the behavior of signals is changed relative to the above indicators, it means that there are problems. Next, the most common types of turn signals will be listed:

1) turns not blinking

This problem will be easier to decide if you familiarize yourself with the basic principle of the relay work. The current that passes through the lamps is heating the measuring resistor - an element that determines the need to turn on at the desired moment of a lamp. Accordingly, the resistance of the lamp, differing from the nominal, changes the time for which the turn signal turns on - it begins to blink.

In this situation, you need to knock on the relay slightly. This will help if there is a weak contact or moisture hit. If the relay was replaced, and the turn signal still does not flash, but constantly continues to burn, then the problem is in a weak contact with the safety unit. In this case, the replacement of the fuse with the resistance value radically differing with the nominal one should help.

2) one turn signal does not work

If only one turn signal does not work, it is in no way connected with the faulty relay.Then there would be a failure immediately in both turn signals. The first option that can come to mind is a blown light bulb, or violations in the wiring or cartridge. The new replacement light should not only be included in the turn slot, but also to be the same power that is indicated on the ceiling. If, in the case of the replacement of the bulb, the turn signal did not earn, then inspect the cartridge. There may be traces of oxidation, which will need to be removed by proper or sandpaper.

Also, the light can sit very tightly on the contacts that need to be adjusted using the taps. It is necessary to do this with the highest possible caution so as not to close the contacts. This can lead to another problem - turn signals will begin to work in a chess order. If the cartridge is in excellent condition, then the problem lies in the wiring itself. First, make sure that the wire is firmly soldered to the cartridge. You can not allow the closure of the wires between themselves or on the mass on the car's iron case.

3) Emergency lights do not flash

In this case, the problem lies unequivocally in the relay. It must be replaced. Another reason for the non-working turn signal may be the switch. To check it, get to a stealing switch lever and unmount it. If emergency lights do not work with good turn signals, simply replace the button that is responsible for turning on the alarm.

4) turning shines not enough brightly

If they emit dim light, it means that the model and power of the bulb should be checked. If everything is normal, you just need to clean the contacts of the bulbs.

5) Turning Relay Clicks

This is not the norm. The whole "salt" is enclosed in contacts of the mounting block relay. Such sounds occur in cases of too dense adjacent to contact or its oxidation. It leads to this and poorly working relay. Install a new relay or read the contacts.

If the rotation pointer does not provide signs of life on one side of the car. No back, nor in front, it means that the problems arose with a steering wheel switch, a contact is lost or the entire relay broke. Electrical circuit The rotary pointer is protected by an 8-ampered fuse, which is located in the mounting block. If it breaks, then such a trouble may occur as a refusal of turn signals on one side of the car. The light alarm system provides safe traffic, so every motorist is obliged to carry the light bulbs with you.

How to indicate the direction of movement with defective turn signals?

As you already understood, there are such cases that light signals, as well as sometimes and sound, it is impossible to express their intentions on the road. That's why we will further and tell you how to indicate the direction of movement of hand gestures. A certain number of such manipulations is fixed in traffic rules.

1) If the left turn signal does not work, you need to pull the left hand aside from the window.

2) To indicate the right rotation from the window, the left hand bent, bent at the right corner of the brush upwards.

3) The brake signal is served by raising your hands.

Besides:

1) Looking with hand to the driver of a pedestrian.

2) In the event that your car strangely behaves on the road, you will be shown in the side of the curb.

3) If the driver forgot to turn on the light, he will remind him of a gesture that looks like a flashing light bulb.

4) If you have forgotten to close the trunk, then you will show it the palm cotton signal in the air. And the unclosed door or the belt pressed to her will be shown cotton on the door.

5) If you have a circle in the air in the air, your car lowered one of the wheels.

Rotary lights are an integral element of optics in any modern car. Their destination is to prevent other participants. road The fact that the driver plans to make maneuver. For what reasons are not an accident, how to check the efficiency of optical elements and how to repair their repair. We will tell about this below.

Causes of failure of turn signals and accidents

Independent diagnostics of car lighting

There are several situations in which you can determine that optics need to be diagnosed:

1. Turns do not blink, but burn. Such a fault indicates the failure of the relay, in particular, we are talking about its electromagnetic component. The electromagnet itself could be closed in one of the provisions, as a result of which he cannot return to the initial state.
2. Rotary lights blink very quickly or very slowly. In this case, the problem may be covered not only in the relay. In some cases, such a kind is manifested when the driver uses non-relevant sources of lighting. So when buying new light bulbs you need to make sure that they correspond to the raid set by the manufacturer's manufacturer.
3. Optics does not work at all. That is, the bulbs of the rotary lights do not flicker, on the tidy, the corresponding indicators are also not lit. In addition, there are no characteristic clicks that appear when the rotary lights are turned on. With such symptoms, the reasons for the problem may be many, we will describe more about their diagnostics below (the author of the video is the Steel Horse channel).

As for the diagnosis, it is performed in several stages:

1. First of all, you need to make sure that all sensors and indicators work on the tidy. If they do not function, then you need to diagnose safety devices.
2. If all devices work in normal mode, then you need to turn on the light alarm button and diagnose all illumination sources in the headlights. That is, check the front, rear, as well as side (if available) lights.
3. In the event that the signaling at activation does not function, then you need to check the functionality of the relay, as well as check the power on the outputs. To do this, dismantle the relay from the landing place, and then, using a control light, connect it to the place of installation (to the plus), and the other to the car body or battery. The ignition does not need to be included. If no power, most likely, the reason lies in the outstanding safety device, breaking the emergency button or damage to electrocups. Also, the essence of the problem can be wounded in bad contact in the connecting plugs.
4. In the event that the plus on the contacts are available, then try closing two relay outputs with copper wiring. If all the electrocups, as well as the plugs of the connection, are working, then all turn signals should light up. In this case, the malfunction must be sought in the relay.
5. If the bulbs did not burn after the actions made, then most likely, the cause of the malfunction is to control the emergency control button. However, in practice it happens quite rarely, it is often a closure in the chain. By the way, it is when the closure can lead to a breakdown of the relay, therefore, before replacing the element failed, you need to eliminate the closure.
6. In the event that the emergency operates, this suggests that safety devices and working relays, accordingly, you need to proceed to the diagnostics of the button itself. First of all, it is necessary to digitize the positive conclusion, as in the case of a relay check, with ignition, as well as the emergency button must be activated. If the diagnosis has shown that the plus is absent, this suggests that it is necessary to check the button itself in more detail. Remove it from the landing place and check the connection circuit. If no power, then you need to search for a wiring from the tidy to the button itself.
   If the power is available, it will be necessary to close the conclusions at the installation site, the ignition does not turn off, after which the turn signs must be activated (from any side). When you turn on the sources of lighting, the replacement button is subject to a control button, but if there is no power, then you need to check the power in the emergency relay. In the absence of nutrition, the problem is most likely lies in the cliff in the connective electrocups from the control key to the block with safety devices.

Repair of pointers of turns and emergency alarms do it yourself

If the turns are disappeared, as well as an emergency, then you can try to solve such a problem with your own hands:

1. When the safety element is breakdown and the details failed to be replaced. If the reason lies in the closure, before replacement it is necessary to check all the electrocups in which it could occur. Only after the cause of the closure and voltage jumps will be eliminated, the devices must be changed.
2. If it failed, it just needs to be changed. On how to diagnose this detail, we have already told.
3. As for the diagnosis of electrical caps, it is carried out using the tester. When identifying damaged areas, the wire is subject to replacement. When laying them, make sure that the wiring does not come into contact with the moving elements of the body. It is also recommended to further exist new wires to increase the reliability of isolation.
4. If the reason is the bulbs, then all blurry lighting sources are subject to replacement. In the front I. rear heads The lamps are changed by removing protection from headlights, disconnects from the lamp of the power circuit, as well as the winding source from the seat and its replacement to the new one. If the lamps do not work in the side headers, then, as a rule, to dismantle the sources of lighting itself, the ceiling itself should be pushed with a screwdriver, then turn off the power wire and remove the device.
5. If the reason lies in the steering wheel switch, then this device must be disassembled and check. As a rule, the reason for the switch of the switch lies in bad contact or in its erasure. In this case, the switch changed to the new one. As for contacts (no matter where - on connections or buttons), it is desirable to clean them.
6. It should also be checked all the plugs and connectors, because it is possible that the problem is in bad contact on them. Covered contacts are subject to clean with an iron brush or sandpaper. If the contacts are overloaded, they will need to be changed.

With the situation when turn signals and accidents VAZ 2110 or other models do not work, there is a considerable part of the Vase owners, and often the problem finds them surprise. The most common reason why turn signals on the VAZ 2109 do not work, it is the fact that the automotive electrician failed.

By the way, most of Vases are equipped with similar electrical strokes that are repaired in the same way, therefore tips are relevant for both the model 2109 and other VAZ models.

Causes of breakdown

In order to prevent the situation when the rotary and emergency lights do not function, determine the reason why they broke. To the most frequent factors breakdown electricians in the car include:

• depressurization. It causes the water and dirt into the electrician;
• oxidation. This happens on the terminals and leads to the loss of contact. See it simple: when turning turns off, and you disassemble the optics, you will see a green color. To remove it, consider it with the help of a vet and try to power the contact;
• fuse breakdown. In order not to fall into a situation where emergency lighting stopped functioning, find a fuse responsible for turns (for example, K2). Next you will need to just replace it. In addition to the failure of the fuse, you may encounter the problem of replacing its contacts;

• light bulb. If the lack of light occurred for this reason, simply replace the lamp to the new one;
• breakdown switch or buttons. If turn signals and accidents do not work, get to the reservoir to the switch, located at the wheel, and disassemble it. You can simply replace the button;
• cut wiring.

How to fix

When turn signals and accidents do not work, the electrician in the car, most often "guilty" the relay is responsible for the supply of voltage.

To prevent the emergence of a problem in the future, follow the following actions:

• find out where the relay is. The scheme of its placement is indicated in the instructions attached to the car;
• let's knock on the relay. Often, the reason lies in a banal "sticking", and the raven blow renews the work of optics;
• if the measures did not help, and you still do not function lighting devices, replace the relay, because the product is inexpensive.

Do not work can be like a single turn sign ("turns") and two, or all at once, etc., in different combinations.

Causes of rotation indicators malfunction

1. One turning pointer is not working (front or rear).

Blocked light bulb

When the light bulb in one or more turning signs on VAZ 2108, 2109, 21099 can be blinking with double frequency. We are visually installed where the light burned out, in turn including direction indicators. We replace the light bulb.

Oxidized cartridge bulb

Turn the light bulb several times in the cartridge to restore contact.

Oxidized or weakened wire connections

We check the cartridges and pads of the front turn signals (in the front block headlamps and on the wings) and the connecting blocks of the rear lights of the car.

Disappeared

All lamps and lamps of cars VAZ 2108, 2109, 21099 have a negative wire, so it should be checked with "mass" contact.

Blocked the track in the hinds of the rear lights

2. Do not work two rear repeater, or two front.

Four first reasons

light bulbs burned out, their cartridges were oxidized, the contacts were oxidized in the connecting blocks of the rotation indicators (on the block of headlights and "turn signals" on the wings), the mass was disappeared.

Open in the wires coming from the mounting unit to back lanterns

- In some cases, at the same time, all direction signs can burn with permanent light not blinking. In this case, it is necessary to replace the rotation pointer relay in the mounting block.
