Priora front turn signal does not work reasons

January 22, 2016 Lada.Online 149 862 64

Many owners of a Lada Priora, Grant or Kalina 2 are faced with a malfunction in the direction indicators. Based on past experience, they begin to look for the cause of the failure with the relay or fuse, but they cannot find them. Let's look at how the turn signal circuit diagram works and the procedure for troubleshooting.

Tips for motorists

When the driver of a Lada Priora passenger car finds himself in a situation with direction indicators that have refused to work, then in order to get to his home or place of repair, he will have to remember the Rules of the Road, which says how to duplicate the direction indicator signals using his left hand.

The simplest malfunction leading to the failure of the turn signals is the burnout of the filament in one of the lamps. In this case, the turn signal lamp installed on the instrument panel begins to blink at double frequency. In this situation, the driver needs to stop, get out of the car and determine where he will have to change the faulty turn signal lamp. When replacing a lamp, he must remember that it must be exactly the same power as the burnt one.

But other turn signal malfunctions are much more difficult for the driver to deal with, since their operation is controlled by the turn signal switch located inside the electrical package controller, and without knowledge of electrical engineering you are unlikely to be able to find a malfunction there. The only thing the driver himself can do is replace the faulty power package controller with a new one. To find it, you will need to remove the lining on both sides of the floor tunnel, but before you begin this work, disconnect the battery by removing the negative terminal.

The direction indicators may also fail to function due to failure of the steering switch. The most innocent malfunction under the steering switch is the inability to independently return it to the neutral position. In this case, the driver can continue to operate the Lada Priora car, although he will need to remember to turn off the turn indicators after performing the maneuver.

Salam everyone, this is a question, the right turn signal and emergency lights of the Priora 2013 do not work, who knows?

Check the fuse first and the turn signal relay.

Many Lada Priora car owners are faced with a malfunction in the direction indicators. Based on past experience, they begin to look for the cause of the failure with the relay or fuse, but they cannot find them. Let's look at how the turn signal circuit diagram works and the procedure for troubleshooting.

Self-diagnosis of car lighting devices

There are several situations in which you can determine that optics need diagnostics:

The turns do not flash, but light up. Such a malfunction indicates the failure of the relay, in particular, we are talking about its electromagnetic component. The electromagnet itself could close in one of the positions, as a result of which it cannot return to its initial state.
The turning lights flash very quickly or very slowly. In this case, the problem may lie not only in the relay. In some cases, this type of malfunction occurs when the driver uses inappropriate lighting sources. So when purchasing new light bulbs, you need to make sure that they correspond to the rating set by the car manufacturer.
The optics don't work at all. That is, the turning light bulbs do not flicker, and the corresponding indicators on the dashboard also do not light up. In addition, there are no characteristic clicks that appear when turning on the turning lights. With such symptoms, there can be many reasons for the problem; we will tell you more about their diagnosis below (the author of the video is the Steel Horse channel).

As for diagnostics, it is performed in several stages:

First of all, you need to make sure that all sensors and indicators on the device are working. If they do not function, then it is necessary to diagnose the safety devices.
If all devices are operating in normal mode, then you next need to turn on the light alarm button and diagnose all light sources in the headlights. That is, check the front, rear, and side (if any) lights.
If the alarm does not function when activated, you need to check the functionality of the relay, and also check the power supply at the terminals. To do this, remove the relay from its mounting location, and then, using a test light, connect one of its contacts to the installation site (to the positive), and the other to the car body or battery. There is no need to turn on the ignition. If there is no power, then most likely the reason lies in a failed safety device, a broken hazard warning button, or a damaged electrical circuit. Also, the essence of the problem may lie in poor contact in the connecting plugs.
If there is a plus on the contacts, then try shorting the two relay terminals using copper wiring. If all electrical circuits, as well as the connection plugs, are working properly, then all turn signals should light up. In this case, the fault must be looked for in the relay.
If the lights do not light up after the steps you have performed, then most likely the cause of the malfunction lies in the emergency light control button. However, in practice this happens quite rarely; there is often a short circuit in the circuit. By the way, it is a short circuit that can lead to a breakdown of the relay, therefore, before replacing the failed element, you need to eliminate the short circuit.
If the emergency signal is functioning, this indicates that the safety devices and relays are working; accordingly, you need to start diagnosing the button itself. First of all, you need to diagnose the positive terminal, as in the case of checking the relay, while the ignition, as well as the hazard warning button, must be activated. If the diagnostics showed that there is no plus, this indicates that the button itself needs to be checked in more detail. Remove it from its seat and check the connection circuit. If there is no power, then you need to look for a break in the wiring from the tidy to the button itself. If there is power, then it will be necessary to short-circuit the terminals at the installation site, the ignition does not turn off, after which the direction indicators must be activated (on either side). When the lighting sources are turned on, the control button must be replaced, but if there is no power, then you need to check the power in the emergency relay. If there is no power, the problem most likely lies in a break in the connecting electrical circuit from the control key to the block with safety devices.

Lada Priora turn signal diagram

The turn signal circuit on the Priora differs from the usual one, where a relay and a fuse were used. The function of the Priora turn relay is performed by the electrical package control controller (CPC), which is located under the panel next to the ECU. It receives input (negative) signals to contacts (X2-7 and X2-8) from the steering column switches and the hazard warning button. At the output, the TsBKE block forms “pluses” on the contacts (X1-14 and X1-15), which go to the light bulbs in the headlights and lanterns. The clicks of the turn signals are not produced by the relay, but by a buzzer on the unit board.

Causes of malfunctions in the operation of turn signals

Approximate procedure if the turn signals fail:

Check the serviceability of the lamp (if it is burnt out, the indicator in the instrument cluster will blink twice as often). If necessary, replace the lamp with a new one;
Check the “grounds” that are located next to the headlight unit and flashlight. Clean the terminals;
Check the steering column switch (example: the contact is stuck and the turn signals do not turn off). Replace it with a known good one, or check it by closing the contacts of the block 49a and 49aL (for the left) or 49a and 49aR (for the right). If the turn signals work, there is a fault in the steering column switch;
Check the hazard warning button in the same way;
Check the wiring to the electrical accessories control unit (example: the rear wall of the radio tape recorder rests against the wires that come from the emergency lights and contact is lost);
Check for the presence of a “plus” on the TsBKE block (X1-14 and X1-15);
Check the wiring from the TsBKE to the lamps. Disconnect the block with wires X1 and apply power through a 5A fuse to pins 14 and 15 of connector X1. (example: if the left or right turn signals on a Priora do not work, then it is possible that when installing the wing, a self-tapping screw got into the wiring harness and caused a short circuit).
The reason is the alarm (for example, the diodes are burned out or the relay is stuck). You should disconnect the alarm connection points to the electrical package control unit and check the operation of the turn signals;
CBKE does not work. Check fuse F31. If there are malfunctions in the operation of the CBKE (example: the left turn signal is constantly on), then you should contact a service station to repair or replace it. In some cases, the reason for the failure of the turn signals was poor contact in the CBKE; the problem was solved by simply turning the unit upside down.

How to indicate the direction of travel if the turn signals are faulty

In some cases, it is not possible to use turn signals. For example, when they are faulty, blocked by foreign objects, or not provided for by the design. The traffic rules provide guidance in this regard.

a raised hand indicates the driver's intention to brake.
a hand extended horizontally to the left warns of the intention to turn left or change lanes to the left.
an outstretched right arm or a bent left arm at the elbow, looking up with the hand, speaks of the above maneuvers, but to the right.

In addition to these hand signs, there are also unofficial, but no less useful:

Flashing your headlights to an oncoming driver: there is danger ahead or turn off your high beams.
A brief activation of the hazard warning lights means gratitude for allowing you into the next row or an apology for a sudden maneuver.

Thorough examination of technical condition

To diagnose and eliminate the malfunction, you should visit a service station. If you have experience and the necessary equipment, you can do everything yourself. This will require 1-2 hours of free time. Among the most common causes, car mechanics identify a short circuit or physical wear of the mechanism. Regardless of this, the procedure is as follows:

Possible causes of the malfunction include damage to the wiring leading to the electrical package control unit. One of the most common examples: an incorrectly installed radio tape recorder pinches the wires, which leads to a short circuit. Do not lose sight of the wiring connecting the light bulbs and the CBKE. You can verify that the circuit is working properly as follows:

Tips for motorists

Good day, comrades. This is the situation. The turn signal on the left side has failed and does not light up, not on the front headlight on the left, not on the fender, not on the rear light. The light bulbs are all intact. The right side works. When the emergency lights are turned on, only the right side blinks, the left does not blink either. When I turn on the right turn signal, the turn signal clicks are normal, when I turn on the left turn signal, the clicks are fast. But it doesn’t burn(((What could be the matter?!

Fuses and relays in Lada Priora, electrical diagrams

Lada Priora is another car in the line of new VAZ cars, which is gaining popularity among segments of the population. External similarities with the 10th model attract the attention of young people; the relatively low price is also a reason for purchase for most car enthusiasts. Along with the growth in popularity, the owners of this model are gaining experience in repair and maintenance, which is becoming more and more every year.

If your Priora has electrical problems, do not rush to get upset; first, check the fuses and relays in your Lada Priora. These are the ones that will be discussed in this article.

Fuse box in the passenger compartment of VAZ-2170, -2171, -2172

The fuse box in Priora is located at the bottom of the dashboard, on the left side of the steering wheel. To get to it, you need to open the cover, which is held on by three latches. Rotate each locking knob 90 degrees and pull the lid down and it will snap open.

Fuses in the interior mounting block

F1 (25 A) - radiator cooling fan . If your fan does not work, check its motor by applying 12 V directly to it from the battery. If the engine is working properly, then most likely the problem is in the wiring or connectors. Check the serviceability of relay K1.

The fan in the Priora usually turns on at a temperature of 105-110 degrees. Do not allow the engine to overheat, watch the arrow of the temperature sensor.

Repair and operation of the VAZ 2108 2109 21099 car

If the turn signals on the VAZ 2109 do not work, then driving the car should be stopped. Because other drivers will not see where you are turning and an emergency situation will arise. This is also scary because many do not immediately notice that their turn signals do not work and continue to drive with non-working turn signals. It is very easy to understand that the turn signals on the VAZ 2109 do not work; turn on the turn signal and look at the turn signal on the instrument panel.

Turn switch VAZ 2109

The light on the instrument panel should blink. Moreover, if the engine is not started, you will hear clicks - this is the turn relay clicking. If the light on the instrument panel does not blink, but is on, it means the turns do not work. There are several reasons why the turn signals on the VAZ 2109 do not work: 1) Malfunction of the turn relay 2) Burnt out turn signal bulb

1) If the turn signal relay is faulty, the light on the instrument panel lights up green without blinking. However, this does not mean that your turn signal relay is faulty.

There may well be poor contact between the turn relay and the relay socket in the mounting block. This is easy to check - turn on the turn and move the turn relay.

The window regulator does not work on the Lada Priora

On a VAZ-2170 Priora passenger car, depending on the configuration, electric windows can be installed only on the two front doors (then the rear ones will be manual) or electric windows can be installed on all four doors. Moreover, the window lifters on the front doors will be cable or rack and pinion, and on the rear doors, only cable ones.

Malfunctions leading to failure of power windows can be divided into two groups . The first group of faults is associated with electrical problems, and the second with purely mechanical ones.

There are significantly fewer failures associated with mechanical faults than with electrical faults.

These include: cutting off the teeth of the plastic gear of the gearbox and problems with the cable drive, which is stretched during operation, which sometimes leads to it jumping off the guide rollers.

all power windows fail to operate, you will have to check the integrity of the 30-amp fuse F31 of the central electrical package control unit, located in the mounting block.

If only the rear power windows do not want to open using the control buttons located on the doors, but they are activated from the central control unit, then the reason will need to be looked for in the locking switch for the rear windows.

It will have to be checked with a tester for current flow in the position when it is turned off.

If one window lifter , which they are trying to turn on from the central control unit, then it will be necessary to check its operation using the switch located on the door.

If it is triggered by this switch, then you will have to check the switch of the central unit for current flow, and if it does not trigger, then you will have to check the serviceability of the electric motor, first checking whether voltage is supplied to it.

If there is voltage, the electric motor is faulty, and if there is no voltage, then you will need to check the wires going to it.

In the electric window lifter motor, the most likely malfunctions may be wear or sticking of the commutator brushes. Hanging of the brushes occurs due to the fact that the brush holder is made of plastic and when heated it can melt slightly, and this leads to the fact that the brush loses its mobility and at the slightest wear it comes off the commutator.

Why are glass closers needed?

Installing a glass closer

The power windows available on the Lada Priora are limited in their functions. They are inconvenient because they raise or lower the windows only when you hold down the security mode button. This creates some inconvenience when you turn off the ignition in a hurry, get out of the car and suddenly remember that you didn’t close the windows in the car.

Again, you need to do all the procedures in reverse order: insert the key into the ignition, press the power window buttons. Or you can completely forget that the windows are left open, and then uninvited guests can get into the car.

The ideal option is to close the windows independently when arming, as well as to operate the windows in the car when the engine is off. In such cases, a window closer of the “Master v1.10” type comes to the rescue. Its cost is only 700 rubles. It should be noted that when installing the door closer, you do not need to remove the door trim.

In addition, when using the glass lift only in the first function mode, there is no need to cut the existing wiring, and the installation procedure will only take 5 minutes.

Window lifter does not work - repair

If the window regulator on your car has stopped working, there could be many reasons for this. But, in general, all problems can be combined into two large groups: electrical failures and mechanical defects of the mechanism. In both cases, everything can be fixed with your own hands. In this article, we will analyze the main problems from both groups.

I had a permanent short circuit on the left side. Diagnosis: body electronics control unit. They changed it under warranty, but the officials have 11 thousand rubles. with work.

The Central Unit of Body Electronics (CBEC) needs to be replaced; the microcircuits in it responsible for one of the cornering sides are burning out. I had the same thing on my Priora, it was changed at the dealer under warranty. I must say, you were lucky, some of them had their cars completely burnt out because of it. The device itself controls all the electronics, BUT! not protected by anything, not even the simplest fuse for protection. And when the microcircuit inside the block short-circuits, it stupidly burns with a blue flame. They showed me the block removed from my car, the body was badly melted, how it didn’t catch fire is a mystery...

Yeah, I bought a new one, I wanted to change it myself, but they said it was better to entrust this matter to a specialist and not save money. They changed it for me and made an adaptation. In general, everything is fine. ))

Where is he located and not in the know?

I just saw that I was a fellow countryman. )))) A friend had exactly the same problem, they took this comfort unit for 36,000

Why do we need turn signals?

Turn indicators are a mandatory attribute of a modern car. They are usually located in the front, back and sides. In some cases, the turn signals “move” to the wing or to the rear view mirrors. Additional lights are installed if the visibility of the main signals is limited, for example, by equipment on special equipment or a trailer as part of a road train. The serviceability of turn signals ensures mutual understanding of drivers on the road.

Now a car enthusiast can check at any time whether the turn signal light is on or not. But it was not always so. Such devices first appeared on cars several decades ago. At first they were complex mechanical products, and their activation was accompanied by a loud crash and frequent breakdowns. The first copies were installed at the driver's request, so they were purchased separately. Sweden has always been ahead of the rest in road safety. It offered various devices for its cars designed to signal the driver's intentions while driving using pop-up flags and other moving elements.

When a car's turn signal light comes on, those around them understand that the driver is about to make a maneuver. Traffic rules require the use of a turn signal to indicate the intention to make a turn, turn or other action associated with a change in the position of the vehicle on the roadway. The turn signal lights up after simply pressing the lever.

If the turn signal bulb breaks, you must signal with your hand extended to the side. This technique is also used by cyclists and horse-drawn cart drivers.

Turn signal bulbs must be in good working order not only for traffic safety, but also in order to save the contents of your wallet, since the timely use of car light alarms is regulated by traffic rules. Violation is punishable by a warning or a fine.
