The signal does not work on the VAZ 2115

When I did the camber I noticed that the signal was gone.
Initially, I was guilty of the wiring and the black box. Having crawled around under the hood enough, it dawned on me. When you pressed the signal, there was no characteristic click of the relay, that is, nothing reached the black box. I had to remove the steering wheel and see worn out contacts near the central part of the steering column switches.

To replace this whole thing you need to: 1. Remove the steering shaft casing 2. Remove the trim on the steering wheel (fret label), there are two bolts under it. Unscrew and pull off cover 3. Next you need to remove the steering wheel. To make it easier to unscrew the nut, block the steering wheel and unscrew the nut. The main thing is not to forget to put the marks (to correctly put the steering wheel in place). 4. Take out the turn signal switch knob. We do not remove the right switch yet (it rested on the ignition switch). 5. Unscrew the bolt that holds the central part on the steering shaft and pull the central part towards you, remove the right switch.

Well, it’s natural to perform the assembly in the reverse order)) Good luck to everyone on the roads

What to do if the sound signal on the VAZ 2106 does not work

A non-functioning horn on a car is a very dangerous malfunction. The most unpleasant thing is that they find out about this breakdown just when the signal is needed most - in a dangerous situation on the road. What could cause the signal to fail?

Such a malfunction as a non-functioning sound signal on VAZ 2106 and VAZ 2114 cars is very easy to diagnose and repair in the process, just study the connection diagram and follow the instructions that you will receive after reading the article to the end.

Installing a special application

The sound on your phone suddenly stops working while using an app, making a call, or watching a video? This is an unpleasant situation, however, you should not throw the device in the trash because of this.

If the above remedies do not produce results and the phone does not ring well, you can use the additional application “Earphone mode off”. Some mobile phones show that headphones are connected when in fact they are not. This app is a solution for such a problem. If the headset is still showing, switch to speaker mode, the sound will come from the output speaker.

Step-by-step instructions for replacing and repairing the sound signal of a VAZ 2106

You can adjust the signal without dismantling it. This is done as follows:
The sound elements are adjusted one by one. This turns off the power from the element that is not currently being regulated.
The second GE is regulated in the same way, having first turned off the first one.+
When replacing a faulty electrical element, the power wires are disconnected from it and the nut securing it to the bracket is unscrewed.
The new sound signal is installed in the reverse order.

Settings

Only autorun functions can be configured. To activate programming mode:

Disable security
The ignition key is set to position 0.
Then press the Valet key six times in the main block.
Turn on the ignition
After six beeps, use the same key to select the desired function, and use the key to
key fob select the desired value.

The optimal settings for VAZ - 2115.2114 will be the following: function 12 - set to value 3, function 11 - value 4, function 9 - value 3. To select value 4, press and hold the third button until the melody is played. After playing, press it again.

To check the correct connections, perform the following steps:

Disconnect the yellow cord from block A91 to terminal 15 for a while.
The engine is started using the ignition key

At the same time, the alarm indicator should blink.

The horn button does not work, what should I do?

If, when diagnosing the electrical circuit breaker, the fuse and the circuit breaker relay, no faults are identified, then you need to check the signal activation button on the steering wheel. Since the steering wheel itself is constantly rotating, and the need to sound a signal can arise at any time, there is a moving contact between the steering wheel and the steering column. Using this contact, you can close the circuit even when turning the steering wheel. In addition, the button itself has two more contacts that allow the driver to give a signal with both the left and right hand. Any of these contacts (most often movable) can fail. In this case, you need to clean it and make sure the button is working. This is done as follows.+

We install the car wheels straight. The steering wheel should also not deviate to the side.
Use a screwdriver to pry off the Lada emblem from the steering wheel button.
Using a 24mm socket, unscrew the steering wheel nut located under the emblem.
Holding and slightly rocking the steering wheel with both hands, remove it from the shaft. In this case, if the steering wheel is not removed, you can hit the shaft through the spacer.
Using a Phillips screwdriver, unscrew the four bolts on the back of the steering wheel and remove the horn button
Remove the button from the steering wheel and disconnect the wire from the contact on the steering wheel. Use a needle file or sandpaper to clean the moving contact located near the shaft on the steering column. Slightly bend the contact upward (towards the steering wheel)
On the previously removed signal button, clean both contacts.
We remove and clean the wires and contacts removed from the button

After cleaning the contacts, we assemble the button. At the same time, we make sure that all contacts are in contact with each other.

To prevent the signal from triggering spontaneously, we check whether the springs of the signal button have weakened. If necessary, stretch the springs or replace them with new ones.

We install the steering wheel on the shaft in the position it was before disassembly.

Terms

A fuse is a switching device designed to protect an electrical circuit from overheating.

When current flows through the fuse above the permissible values, its fuse-link burns out, thereby breaking the electrical circuit.

Rated current is the current at which the fuse is capable of operating without load.

The fuse link is the part of the fuse that blows due to exposure to greater current.

Relay - a relay is a switching device designed to relieve contacts on a button. The operating principle of this device is based on the law of electromagnetic induction.

The relay has several selection parameters. This is the current at which the contacts will not melt and heat up; it is called the rated current of the relay, as well as the number of contacts.

Why the cigarette lighter and radio do not work on the VAZ-2114

Some components that belong to the electrical system are interconnected, so drivers often have complaints that the cigarette lighter and radio in the VAZ-2114 car do not work at the same time ✔. Often the cause of a malfunction is the connection of devices whose power exceeds the permitted value.

Connecting autorun

The VAZ-2114 models use an ignition switch with three terminals - 15 (blue wire), 30 (lilac) and 50 (red). Terminal 30 is connected to the battery. When you turn the key, blue wire 15 is connected to this terminal. The third terminal is responsible for the starter.

As it is written in the instructions, it is quite possible to power the alarm from contact 30, from which the lead is made. And the cable from connector X1, yellow, is connected to connector 15.

After all the actions taken, the connection of the tachometer remains. In this case, a loop antenna and a reading device are combined. Connector X3 has a gray-black outgoing wire. It is connected to the tachometer as shown in the VAZ dashboard diagram:

This will allow the alarm to control the speed. And at the very end we connect the ground from the main unit. This is a black cord from connector X3.

Basic fuse faults

Fuses in cars play an essential role, protecting electrical appliances from power surges and short circuits. They take on the impact of such factors and maintain the working condition of the electrical appliance, while burning out themselves. But if this happens regularly, you need to check the fuse box and determine the cause of the breakdown.

Bad contacts

One of the most common reasons for a situation where a fuse does not work is related to the contact group. With frequent voltage surges in most VAZ cars, contacts burn out and plastic melts, which can interrupt the contact of parts. A similar condition is also observed when the contacts have oxidized and become coated.

Broken wiring

When operating a car, malfunctions such as broken wires often occur. To determine for yourself where the accident occurred, you will need a special device (multimeter, tester) with which to check the working condition of the contacts. To find an open circuit, the device is set to ohmmeter mode, and the leads are connected to the circuit being tested. In the place where the wiring is broken, there is high resistance.

Are you a car driver?! Then you can take this simple test and find out. Go to test »

Short circuit

A short circuit occurs when the contacts in the block are strongly oxidized and crossed due to frequent use of the cigarette lighter socket. This condition is indicated by a fuse blowing shortly after replacing it. To determine the short circuit zone, you need:

Inspect the entire area for damage.
Disconnect the section being tested from the main wiring.
Use a multimeter to set the dialing mode.

If there is a short circuit in the area being tested, the device beeps.

Bulb burnout

The contacts of the light bulb are in a common electrical circuit, so when it burns out, the cigarette lighter and radio on the VAZ also stop working. The reason for their burnout may be high voltage, breaks or short circuits in the wiring, water or poor fastening.

Silent Android Speakers

Often the reason why the sound on the phone does not work is situations when the external/internal Android speaker stops working suddenly, in which case the device does not make any sound at all. And also when calling others, they hear nothing. If there is no audibility even in the headphones, then this is probably a hardware problem. You need to check the external and internal Android speaker using the Device Diagnostic Tool.

Diagnostic algorithm - how to find out why there is no sound on a Samsung S4 phone:

Open the hardware kit and enter the key combination * #7353 # to enter the Device Diagnostic Tool menu.
For an external speaker, tap the Speaker icon. If it is working normally, you will hear very loud music coming from the device.
Press "Speaker" again to mute the sound.
For the internal speaker, press the “Melody” key. If everything is fine with the speaker, music will come out of it.
If the device does not pass the test, then the problem is in the software.

In this case, you can use the following tips:

Reboot the phone in the usual way.
Turn off Bluetooth, sometimes the speaker does not work because the device is connected to this device.
If everything is done correctly, then the sound will appear, if not, then the reason explaining why there is no sound on the phone may be a hardware problem, then you will have to send it for repair.

Repair

Finding the reason why the cigarette lighter and radio failed on a VAZ-2114 is not so difficult. Often the problem is hidden in the contact group or in the fuse box.

To eliminate breakdowns associated with poor contacts, you should start by checking all the contact blocks of the wires that go from the fuse box to the cigarette lighter and radio. Insufficient contact and its oxidation lead to breakdown of elements.

Broken wiring cannot be repaired, it can only be replaced with a new one. Some motorists try to solve the problem using the old and proven method, connecting the damaged area with insulating tape. However, experts do not recommend repairing the wiring in such a way that new faults in the form of a short circuit do not appear in the future.

You can solve the short circuit problem by replacing the socket with a better one.

The use of cheap products leads to breakdowns after a short period of time.

Connection diagram

After carefully studying the alarm installation instructions, you can find the following connection diagram:

In this diagram, the designation X2 indicates a six-pin connector. It must be connected according to the diagram above. If you need to install an additional actuator, then it is better to use the diagram given in the instructions.

Now let's figure out how to connect the door sensors. For this purpose, there is a special wire in the connector marked X3.

Reasons why the PP stopped working

In fact, there are not so many of them and the most common are:

The easiest one is poor contact between the panel and the electronic control unit. The problem is solved by replacing the plug or simply cleaning the contacts.
A breakdown in the instrument panel itself or malfunctions. To solve the problem, all connectors are reconnected, taking into account the correct connection diagram.
Malfunctions of the tachometer, speedometer, fuel level controller. In this case, the cause is mechanical or electrical. To troubleshoot problems, replace regulators or check the operation of fuses.
The illumination of the VAZ-1215 software stopped working. In this situation, it is necessary to find out the cause of the problem.

It is unlikely that a simultaneous failure will occur in the operation of the sensors on which the operation of the PP directly depends. If we take into account that they do not work directly with devices, but through an ECU (electronic control unit), then, accordingly, malfunctions will lead to the PP stopping working. In addition, it is worth noting that the engine will also stop working.

There are situations when all devices on the panel stop working simultaneously. In this case, the car driver must check the condition of fuse F16, which has a power of 16 A.

To check, you must turn on the hazard signal or turn signal.
If they don't work, it means the fuse has blown. Therefore, we can conclude that a short circuit has occurred. To fix the problem, check the electrical circuit. However, it also happens that the fuse is intact and in working condition, but the instrument panel on a VAZ-2115 car stops working. Here the reason is much more difficult to find out. The solution to the problem is to remove the instrument panel and check whether voltage is flowing from this fuse to the terminals of the white and red blocks. The white block supplies power to the speedometer, tachometer, and temperature gauge. And the red one is the fuel gauge.

If, as a result of checking, the terminals show a voltage of +12 V, then this indicates that the PCB does not work as a result of poor contact of the wire that goes to the ground of the car. If the +12 V voltage is not reflected at the terminals, then it is necessary to disassemble the mounting block and look for the cause of the problem.

Solving serious problems

How to repair and connect a car horn yourself? installation of sound signals from the Volga

If there are no problems with the settings, and rebooting the device did not help, then you can suspect more serious problems. In this case, it is advisable to immediately contact a service center for diagnostics. If the phone is still under warranty, it is recommended to contact the store where it was purchased.

Change firmware

If you recently reflashed your smartphone, then the reason for the missing sound may well be incorrect firmware of the device. To avoid problems, you must use only original programs.

Clean or replace the speaker

One of the most common problems with sudden loss of sound on a smartphone is problems with the speaker. There may be several reasons for problems:

The speaker is clogged with dust. In this case, the sound may not disappear immediately, but decrease gradually. However, at maximum volume the sound may be slightly audible. You can try to clean the speaker yourself using a soft toothbrush or a thin needle. But if there is no experience in such work, then it is better to entrust the device to a professional;
Short circuit on the coil. This problem may affect the main and earpiece speakers. In this case, the sound does not necessarily disappear completely, most often the interlocutor is simply very hard to hear. Only completely replacing the speaker will fix the problem.

You can understand that it is the speaker that has failed if you connect a headset to your mobile device, no matter wired or wireless. In this case, the sound will be normal. If the problem occurs with the speaker, then nothing can be heard during the call. If you can’t hear any sounds either on the phone or in the headphones, then you need to look for the problem further. In this case, it is better to entrust your mobile phone to professionals.

Replace the cable

This part often breaks in clamshell mobile phones. The cable often fails on mobile phones that are actively used. You can suspect that the cable is worn out based on one sign - the sound is not heard, but besides this, it is impossible to adjust the volume.

Sometimes moisture gets on this part, in which case the contacts oxidize and the cable fails. In this case, there is only one solution - replacing the cable at a service center.

Replace sound card

Complete silence in the speakers and headphones may indicate a failed sound amplification board. Quite often, such a breakdown leads to a complete lack of sound. But more often than not, the volume simply stops being adjusted, remaining at the same level, regardless of the settings. If the volume is set to minimum, it will be impossible to hear the music, the interlocutor, or the soundtrack of the videos.

Such boards most often fail due to mechanical damage and liquid getting inside the mobile phone case. Factory defects of the device, as well as high temperature due to overload of the phone, can lead to such a breakdown. This problem can be solved by replacing the board.

What to do if the VAZ-2115 instrument panel does not work

As mentioned above, it is necessary to establish the cause of the instrument panel malfunction. If they are significant and cannot be repaired, then in this case it is necessary to install a new PCB. For a better outcome when installing the panel, you need to know and follow the following instructions:

Replacement of the instrument panel is carried out strictly in accordance with the pinout.
First you need to disconnect the cable going to the cigarette lighter.
Dismantle the control panel. It is necessary to unscrew 2 screws located along the edges, top and bottom of the instrument panel.
The next step will be to dismantle the lining. The difficulty is that it is held in place by clamps, so you need to swing it a little.
After this, all wires going to the instrument panel are disconnected (light alarm connector, clock, speedometer, fuel level sensor).
The very last step is to dismantle the control panel. All the bolts that secure it are unscrewed. At this stage, you should perform actions very carefully, as you can really damage the wiring.

After all the above steps, the process of dismantling the control panel can be called complete. If there is a need to change the light bulbs, you need to remove the sockets and install new ones. When dismantling the cartridges, they are turned counterclockwise. This should be done with extreme caution to avoid damage. Collection must be done in the opposite direction.

By following all the rules for installing the instrument panel, you can independently solve all the problems associated with its operation. If this fails, you will have to seek help from a car service to correct problems with the PP.

Bluetooth speaker does not make sound

How to connect a signal to a VAZ 2107
Another common situation is that users do not hear sounds when connecting the device to a Bluetooth speaker. Before you take serious steps to fix this type of problem, you need to check if the Bluetooth speaker/handset is working on another phone, if so, then you need to connect the device again, then go to Settings>Bluetooth, double-click the icon “Byte headset”, “Listen to music”.

A failure can also occur if there are many similar devices stored in the phone’s Bluetooth menu, and the user forgets to “disable” these devices, especially if he does not use them very often. All unnecessary Bluetooth applications must be closed forcibly. This will not only clear the list of devices, but will also help you remove and reconnect a device that is used regularly.

Setting procedure:

In the Bluetooth menu, select the desired speaker from the list by clicking to the right of its name.
Select the “Close device” function.
Click "Forget Device" again to confirm.
Press the Bluetooth button on the speaker to start the pairing process again and select it from the list of devices on your phone/tablet when it appears again.

Sound should now come from the Bluetooth speaker. If not, you need to contact the service and ask them to fix the error.
