The instrument panel of the VAZ 2115 injector 8 valves does not work reasons

Some owners of a VAZ-2115 car sometimes encounter such a problem as a non-working instrument panel. Often this malfunction is caused by unqualified interventions when eliminating various problems with the car. In addition, the problem may begin due to a manufacturing defect. To identify the cause of the breakdown, you need to contact a car service for diagnostics.

Devices on VAZ 2115 do not work

The instrument cluster of the VAZ-2115 passenger car is considered a fairly reliable device, but, as is known, in any production some kind of defect may occur, which subsequently leads to its failure to operate. Well, the second common reason for the complete failure of instrument readings is unqualified intervention when eliminating local faults in it.

The likelihood that all the sensors on which the operation of the devices depends will fail simultaneously is negligible. But, given that the sensors do not work directly with the instruments, but through the electronic control unit, its failure will naturally lead to the fact that the instrument cluster will not work. Moreover, along with it, the engine will not work.

The speedometer needle is driven by a stepper motor. The tachometer has a similar design, but the fuel level indicator in the gas tank and the coolant temperature indicator in the engine cooling system are driven by magnetoelectric mechanisms. From this we can conclude that their operation directly depends on the presence of supply voltage at the terminals of the instrument cluster terminals. Therefore, if they all refuse to work at the same time, then the driver will first need to check fuse F16 (15A).

To check the fuse, you won’t even need to open the hood and mounting block; just turn on the turn signals or hazard warning lights. If they do not work, it means that fuse F16 has blown and the driver will have to look for the cause of its failure by sequentially checking all the electrical circuits that it protects.

When fuse F16 turns out to be intact, then you will have to remove the instrument cluster and check whether voltage is supplied from this fuse to terminals 9 and 10 of the white block X1 and terminal 2 of the red block X2, since the speedometer, tachometer, temperature gauge receive power through the white block, and through red block fuel level indicator. If there is +12 volt power at these terminals, it means that the devices do not work due to poor contact of the wire going to the ground of the car body (terminal 1 of block X1 and terminal 3 of block X2).

If there is no +12 volt power supply at these terminals, then you will have to disassemble the mounting block, in which most likely the track on the board going from the fuse terminal F16 to the power terminal of the instrument cluster has oxidized or burned out.

Why the instrument panel backlight does not light up, a couple more reasons

I'll give you an example from my life. I went fishing in the summer with my friend in a VAZ 2115 car. On the way, before arriving at the place, the instrument panel lights stopped lighting up. The malfunction would seem insignificant for daytime, but in the evening and at night the driver in this situation is unable to concentrate his attention on the instrument readings, which means it was necessary to eliminate the malfunction.

What to do in this situation, where should you look for the cause of the malfunction? Spare bulbs were available, fuses were missing. Or maybe the reason is not in the fuses, but in a break or lack of contact? In general, it’s impossible to immediately figure out where to start. That is, we asked ourselves a single thought: How can we determine the malfunction in this case?

The board is damaged

Repair and diagnostic operations of the dashboard board.

The worst thing that can happen and what every car enthusiast fears is the burning of the dashboard, or rather the control board.

READ Renault Megane 2 cigarette lighter does not work

There is only one way out - replacement, but many car enthusiasts manage to resurrect such elements using a soldering iron. Although, as practice shows, in 50% of cases it does not last long.

The main reason for board burning is a short circuit. In this case, often the place where the wiring is connected and the most vulnerable point – the backlight – is on fire. If incandescent lamps are installed, they will be dark or black, but the LED backlight burns out in the places where the solder is connected to the board.

If the light in the dashboard goes out, it is recommended to contact a car service center, where everything will be fixed or replaced quickly and efficiently. The main reason can rightfully be considered a short circuit. and if the fuse fails, or the impulse passes before it burns out, then the consequences can be very diverse.

Experienced car enthusiast. I have an automotive education, namely: an engine repair mechanic. At the beginning of my career there was a VAZ-2107, then a BMW 5-series, a Toyota Supra and a right-hand drive MARK-2. Now the family has 2 cars: Peugeot 407 and Dodge Challenger 2016. I study each car from “A” to “Z”. I have a lot of experience and try to repair everything with my own hands.

Why does the VAZ 2114 instrument panel not work? A massive problem in our auto industry

And is it necessary to create additional troubles and the risk of accidents on the road? So the majority of those to whom this incident happened still get to work (or wherever they were going) by public transport in order to return to solving the problem in the evening on their own or with the help of a familiar mechanic.

Why does the VAZ 2114 instrument panel not work? Offhand, we can name several reasons. However, they may not exhaust the entire list, since the individual characteristics of the car may appear. We will try to talk about this and many other equally interesting things in our article today.

Solution

traditional incandescent lamps,
LED in a plastic socket,
SMD LED is a more expensive and reliable option, a super-bright diode.

The choice will always depend on financial capabilities and lighting preferences

The number of backlight and control lamps is up to 19 pieces. It varies slightly depending on the design of the instrument cluster and the modification of the vehicle. Many car owners choose LEDs due to lower energy consumption and longer service life. This backlight is brighter and gives an interesting bluish color instead of the standard green. But due to the design of the diode, the brightness control of the instrument illumination will not work, always turning it on at full power. On a long road trip at night, this can be distracting and irritating to the eyes. But in any case, the choice of light sources is yours.

If you are going to install LEDs, it is recommended to first check them with a tester for the absence of a short circuit.

Light bulbs

Recently, it has become fashionable to install LED lighting for the VAZ dashboard with your own hands. However, not all car enthusiasts correctly connect it to the on-board network. This can cause the light to go out at the most inopportune moment. So, it’s worth checking the contacts of the entire backlight circuit.

There have been cases where, as a result of bumps, all the light bulbs burned out at once. In this case, you need to look for a breakdown in the wiring, you can get stuck like that again!

The same applies to standard incandescent light bulbs that come with the car from the factory. Thus, a break or burnout of one of the light elements can lead to the fact that the entire backlight stops working. If you run the tester through the entire circuit, you can easily find an open circuit.

The board is damaged

The worst thing that can happen and what every car enthusiast fears is the burning of the dashboard, or rather the control board.

There is only one way out - replacement, but many car enthusiasts manage to resurrect such elements using a soldering iron. Although, as practice shows, in 50% of cases it doesn’t last long.

The most common breakdown

Before digging into the inside of the car, check how securely the ground wire leading to the front panel is secured. A restless passenger in front often simply pulls him out of his place with his feet. To prevent the situation from repeating itself, after fastening it is worth insulating the wire from reach.

Its signs are very characteristic:

All indicators do not work: speedometer, tachometer, odometer, fuel level recorder, coolant temperature sensor;
The rest of the equipment - optics, radio, even the panel backlight - turn on normally and do not act up;
The ignition works properly, the car does not refuse to start;
Fuse F3 is almost 100% blown. It is located in the mounting block and will have to be changed. But first you need to find out why it was covered, otherwise the new one installed will suffer the same fate. In most cases, a short circuit is to blame for burnout. On well-used VAZ-2114, the fuse often blows after each wash. Instead of carrying a spare one, you need to figure out where moisture is getting into it.

If the fuse is intact , this is not a reason to immediately leave it alone. It would be a good idea to remove it and check the contacts: if the fuse is live, but the terminals are oxidized, the circuit will be interrupted, and the device will stop showing any signs of life.

The next weak link : It is the ignition relay. It is located to the left of the steering column, fixed on a pin, so to speak, upside down. You need to remove it and try to make direct contact with the wires. If there are obvious signs of revival on the instrument panel, it immediately becomes clear that the time has come to change the relay.

The display backlight of the Gamma GF115T on-board computer does not work

I became the happy owner of a used VAZ-21093 car. Of course, as with any used car, there are pros and cons. A huge plus was the presence of the Gamma GF115T on-board computer, but later it turned out that the display backlight did not work, and one button was not illuminated. As I learned from the previous owner, the backlight died, and the craftsmen could not fix it; they said that the display itself is the backlight, the display needs to be changed. Well, the device is good, but a backlight that doesn’t work is not very good, especially at night. There was little information on the Internet, so I decided to figure out what was what and maybe help someone. First of all, we remove the on-board computer from the car’s dashboard and take it home for disassembly. Disassemble (unscrew 4 bolts)

, we check the 4 diodes responsible for the button illumination with an ordinary tester,

they are blue, one died, unfortunately, there is no donor at hand, we’ll leave it until better times and move on to the display. We carefully examine the display and notice the inscription CU026 on the side,

We look for a datasheet on the Internet and understand that the backlight is located under the display and is made using 5 5v diodes. There are 2 contacts on the side, we call the tester, nothing. Mark the anode with a + sign on the board with a felt-tip pen. To make it easier to dismantle the backlight, unsolder the speaker (there is a + sign on it, mark it on the board with a felt-tip pen on the side where it is on the speaker, so you don’t forget later), bite off the two backlight contacts and carefully remove the backlight (white plate) from under the display

. Of course, you can buy this element, but we will take a more complicated route and make it ourselves. The substrate has fallen off on one side; we lift it up from the other side and see a microcircuit with soldered diodes. We take it out and think about what to replace it with.

Hard case

Until now, situations have been sorted out when the torpedo still showed some signs of life. If non-working power windows, turn signals, and windshield wipers have been added to the devices, the issue is no longer a matter of relays and fuses.

The contacts on the ignition switch are burnt. In principle, after installing the relay (even on the VAZ-2109 version), this problem rarely arises. However, the possibility remains. The lock is removed, the contacts are checked and, if necessary, cleaned;
Mounting block. There may be burnt tracks on its board. The only thing that will save you is replacing it with a new one. However, the cost is by no means astronomical, and the installation is available as a standalone option.

#2 The on-board computer “went into the shadows” or how the backlight disappeared, part 2

Greetings to all.
Today, a computer repair friend called and said that he was free from his work, which means that he can bring his on-board computer for repairs. I brought him the onboard one, and began to look for exactly the same transistor as the one in the onboard one, but, to our deep regret, we did not find exactly the same one, and the analogues differed slightly in readings. To be on the safe side, it was decided to go to the Chip and Dip store to buy a transistor, which is exactly what I did. After 20 minutes, I was already at his place with a new KT683A transistor, the cost of which is only 16 rubles. Having checked it and made sure that it was working, the master soldered a new transistor in just a couple of minutes, assembled the on-board one and I went to check it.

The result is that everything caught fire, as it should during normal operation. The master did not take a penny for the work, since we have known him for a long time and the work essentially costs him nothing. Thus, to summarize this article - this transistor regulates the brightness of the on-board computer backlight. To prevent its overheating, it is bolted to the heat separator. For anyone who one day encounters a complete lack of backlight on the on-board computer, start your search with the transistor. It won’t be difficult to find it on the board, and perhaps that’s where the problem lies. Great weekend to everyone! And as they say - serviceable cars and neither a nail nor a rod!

Private situations

General signs do not always indicate specific breakdowns. There may be exceptions.

If individual devices refuse to work, it is quite possible that this is their personal problem. You'll have to parse the specific pointer. It may have a cracked gear that needs to be replaced.

Also, why doesn’t the instrument panel of the VAZ 2114 work? If the fuel gauge and tachometer are capricious (either they function, or they don’t react at all), the contacts and the mounting block are normal - you need to do a small check.

Reset is pressed and held, and the ignition is turned on at the same time. Raised arrows indicate the need for further searches. Lifeless - that microcracks have appeared in the shield itself. You will have to remove it and examine all soldering and traces under a magnifying glass. In principle, these are all the main options. If calling all the listed components and parts did not lead to the revival of the instrument panel, your case is individual, and you will have to determine the situation in the company of an experienced auto mechanic.

Replacing dashboard lamps yourself

When the panel lamps stop lighting, you should immediately replace them with new ones. For this job we will need the following arsenal:

Phillips screwdriver
new light bulbs.

Let's get started

First of all, we remove the decorative trim of the radio (since the dashboard and radio are connected to each other, you will have to disturb the music system too), which is held on by fasteners; here it is better to use a screwdriver, threading it under the trim.

The main condition of work is caution. You need to start detaching the cover from the bottom edge. When the bottom edge comes off, you need to pull it towards you a little. Now detach the top edge. Further:

Disconnect the wire directed to the cigarette lighter.
In the same way as we removed the cover from the radio, we remove it from the dashboard. Above the left and right edges we find two self-tapping screws. They need to be unscrewed. We unscrew the screws located at the top and bottom.
We remove the trim with a little effort (since it is also held on by fasteners, so the decorative plate will have to be rocked a little).
We disconnect all the wires: from the alarm system, from the clock, from the headlights and other things.
We remove the control panel itself, for which we unscrew the four screws on which it is held. In order not to damage the wires, it would be better to disconnect them on the one hand.
Now the most important thing. We remove the sockets of the light bulbs that have stopped burning. To remove the cartridges, you need to turn them counterclockwise with a gentle movement. We replace the defective lamps with new ones, wrap them and install the entire structure in the reverse order of disassembly.

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.

How to identify a malfunction

There was no indicator screwdriver, just a small flashlight and some thin copper wire. It was decided to identify a blown fuse in the mounting block by dialing. For this diagnostic method, it was necessary:

disassemble the flashlight;
cut one wire (in the flashlight circuit);
add two small pieces of wire (about the same cross-section) to the ends of the cut wire;
close the flashlight key (turn on the flashlight).

As a result, the result was a homemade device for testing individual circuits and, in particular, for testing fuses in the mounting block located under the hood on the driver's side. You, of course, understood how to use such a “device” (two wires with bare ends are taken, which are subsequently connected to the fuse contacts). The two wires brought out from the flashlight serve as “device probes”, when closed, the flashlight light comes on.

A blown fuse was subsequently found (identified) in the mounting block, this is a 7.5 A fuse F10, which is responsible for lighting:

devices,
engine compartment
and car number.

There was no spare fuse of the same type in reserve and, accordingly, the question arises: How can I replace the fuse?

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.

Reasons for turning off the dashboard on the VAZ 2114

Turning off the dashboard lights does not bode well for either the driver or the car. Because this malfunction is usually followed by others. Therefore, the backlight should be repaired immediately.

You should also understand that if the lights on the dashboard go out, then the problem must be looked for somewhere in the on-board electrical system. This means you can’t do without a multimeter, a soldering iron and electrical tape. Here are the main reasons for turning off the backlight:

fuse burned out;
the light bulbs have burned out (or LEDs - in later VAZ 2114 models the panel is illuminated by them);
the wiring in the on-board electrical network is damaged;
The common contact board of the instrument panel burned out.

Let's consider these points in more detail.

Burnt fuse

80% of cases when the backlight turns off is due to a blown fuse. It is located in a safety block installed under the steering column of the car. Usually the fuse indicated in the documentation as F10 is lit.

It is he who is responsible for the dashboard lighting, side lights and license plate lighting. On early VAZ 2114 models, fuse F10 was brown or red.

On later cars they started putting green ones. It is not difficult to understand that the fuse has blown. It's enough just to inspect it. The housing of a blown fuse may be slightly blackened or melted, and the conductor inside the housing may be severed. The faulty fuse is replaced with a new one. Typically this solves the problem.

Burnt out light bulbs

Dashboard lights operate under less than ideal conditions. They are regularly exposed to shaking, power surges in the car's electrical network and temperature changes. All this significantly reduces their service life. Especially if these are not LEDs, but ordinary incandescent lamps, which were equipped with the first VAZ 2114 models. There are a total of 19 lamps (but this number also varies depending on the year of manufacture of the car, and the number of lamps should be specified in the technical documentation for the car).

Another reason for light bulbs to burn out is their improper installation. This is most often observed on early VAZ 2114 models, where drivers decide to independently replace obsolete incandescent lamps with new LEDs, making some changes to the electrical circuit. Without proper qualifications, this operation is not so easy to perform. Here's what the sequence for replacing light bulbs looks like.

The steering column is lowered to the bottom position until it stops. Above it is the dashboard cover with four mounting screws. They are unscrewed with a Phillips screwdriver.

Wiring damage

Problems with electrical wiring are the worst case. To figure this out on your own, the driver needs to have serious knowledge of electrical engineering. In particular, he must be able to read automotive electrical circuits well. Not all car enthusiasts can boast of such skills. It is for this reason that it is better to entrust the search for a damaged section of on-board electrical wiring to a qualified auto electrician.

His actions boil down to the following: he determines the key sections of the circuit and sequentially “rings” them using a multimeter until he finds a broken section of the wiring. Completing this work may take several minutes or several hours - it all depends on where exactly the circuit break occurred.

Panel contact board problems

If all of the above measures do not lead to anything, the last option remains: damage to the contact board in the dashboard. This part is a combination of several microcircuits. It is not possible to repair it in a garage without special diagnostic equipment. So the car owner has only one option - to replace the entire board. You can purchase it at any auto parts store. It costs about 400 rubles. Let us list the stages of its replacement.

First, all the steps mentioned above in the paragraph on replacing light bulbs are performed.
But instead of unscrewing the bulbs, you should unscrew the four bolts at the corners of the rear wall of the dashboard.
The back wall is carefully removed along with the board, which is attached to the wall with plastic latches.

So, the owner of a VAZ 2114 can solve most problems with the dashboard lighting on his own. All that is required is the ability to use a screwdriver. The exception is the case of damaged wiring. It is strongly recommended that you contact an electrician to identify the damaged area. This will save a lot of time and nerves, which, as we know, are not restored.

VAZ 2115 dashboard stopped working

The search for possible reasons why the VAZ 2114 instrument panel does not work periodically worries one or another owner of cars of this model.
It’s clear that if you don’t see a single parameter on the dashboard, you can only drive, as they say, by touch. True, there are certain specialists who still managed to somehow crawl to the base without all the evidence, but somehow I don’t want to follow their example. And is it necessary to create additional troubles and the risk of accidents on the road? So the majority of those to whom this incident happened still get to work (or wherever they were going) by public transport in order to return to solving the problem in the evening on their own or with the help of a familiar mechanic.

Why lamps burn out or stop working: causes and consequences

Burnt-out lamps complicate driver control over car instrument readings

The backlight operating conditions are not ideal: shaking, temperature changes, possible power surges in the on-board network, and so on. When driving, you must turn on low beam headlights. Along with it, the instrument lighting also turns on. This can shorten the life of the lamps, and over time, not the entire panel is illuminated evenly.

The main danger of lamps burning out in the instrument cluster is that some of them are control lamps. In this case, you may not know about the failure of individual machine components. And uneven illumination looks ugly.

The most common breakdown

Its signs are very characteristic:

All indicators do not work:
speedometer, tachometer, odometer, fuel level recorder, coolant temperature sensor;
The rest of the equipment - optics, radio, even the panel backlight - turn on normally and do not act up;
The ignition works properly, the car does not refuse to start;
Fuse F3 is
almost 100% . It is located in the mounting block and will have to be changed. But first you need to find out why it was covered, otherwise the new one installed will suffer the same fate. In most cases, a short circuit is to blame for burnout. On well-used VAZ-2114, the fuse often blows after each wash. Instead of carrying a spare one, you need to figure out where moisture is getting into it.

If the fuse is intact, this is not a reason to immediately leave it alone. It would be a good idea to remove it and check the contacts: if the fuse is live, but the terminals are oxidized, the circuit will be interrupted, and the device will stop showing any signs of life.

REMOVAL OF THE INSTRUMENT PANEL AND REPLACEMENT OF BULB

To remove the tidy, you need to have a Phillips screwdriver and “dexterous hands”. Replacing light bulbs in the dashboard of a VAZ 2114 is only possible with the panel removed.

To do this, remove the decorative cover of the radio that is connected to it. To do this, use a screwdriver. You need to start from the bottom edge, you need to do everything very carefully so as not to damage the fragile plastic parts. When it moves a little, you should pull it towards you a little and you can release the upper part.

Next, the procedure will be as follows:

You need to disconnect the wire from the cigarette lighter;
The panel cover is removed in much the same way as for a radio, with the difference that there are also two screws and latches;
Again, you need to disconnect all the wires going to the panel;
Four screws are unscrewed and the panel can be removed from its place. This must be done carefully and accurately.

The question of how to change the light bulbs on the instrument panel is not very difficult; even novice drivers can cope with it. You need to find the burnt out light bulb and carefully remove it from the socket. It is removed along with the cartridge. To do this, you need to turn it counterclockwise and pull it out.

After replacing the burnt-out lamp, the socket is installed in the socket, again very carefully. After this, the panel can be put in its place. Installation occurs in reverse order. To avoid the fact that the VAZ 2114 dashboard does not work, do not forget to connect all previously removed wires and connectors to their places.

Recently, many owners of VAZ cars have been engaged in various types of tuning, including upgrading the instrument panel. There are a large number of options for such modernization. You can add white backlighting to the instrument panel, replace lamps with LEDs, and change instrument dials. There are also options where the instrument arrows are illuminated, as well as other modification options.

Hard case

The contacts on the ignition switch are burnt
. In principle, after installing the relay (even on the VAZ-2109 version), this problem rarely arises. However, the possibility remains. The lock is removed, the contacts are checked and, if necessary, cleaned;
Mounting block
. There may be burnt tracks on its board. The only thing that will save you is replacing it with a new one. However, the cost is by no means astronomical, and the installation is available as a standalone option.

Dimension fuse is on

If the fuse is constantly on, then two options are possible:

poor contact in the fuse box;
Somewhere there is a short circuit (short circuit).

We take a 12 volt light bulb and connect two wires to it, + and -, respectively.
We take out the blown fuse and connect the wires from the light bulb to the places where it contacts the block. If the lamp is on, then there is a short circuit somewhere.

The only way to find the location of the short circuit is to turn it off in order and check in the same way everything that this fuse is responsible for.

The main diseases are:

Wires that go to the trunk lid and to the license plate lighting. Most often, they are the ones who fray and short out.
The next weak point, which is why the VAZ 2109 does not light up, then unhook the cable, which is located at the driver’s left foot, which is not on the engine shield, but on the back side of the wing, under the carpet. Having disconnected the cable, we just disconnect the circuit for the license plate illumination and the lampshade.
If after this our light on the fuse box goes out, then we have found the place where it shorts. Next, you need to completely look at the wiring and treat it with electrical tape.

Private situations

General signs do not always indicate specific breakdowns. There may be exceptions.

If individual devices refuse to work, it is quite possible that this is their personal problem. You'll have to parse the specific pointer. It may have a cracked gear that needs to be replaced.

ONE OR MORE LIGHTS ARE NOT BURNING

Let's consider the first variant of malfunctions, when the backlight of the VAZ 2114 instrument panel does not work. You must begin checking the functionality of the backlight by checking the serviceability of the fuse in this circuit. This only applies when all the backlights are off.

The fuse box on this model, as well as on the VAZ 2113 and VAZ cars 2115

, is located in the engine compartment on the driver's side. You need to remove its cover and find the fuse responsible for the backlight, this is F10. It is designed for a current of 7.5 A. If it burns out, replace it with a new one and check the operation of the backlight paws.

Further events can develop as follows: either everything works or it doesn’t. If the instrument panel backlight works, the test ends here, otherwise it is necessary to continue troubleshooting. It may be due to poor contact of the connectors or an open circuit in the power supply of the backlight lamps.

To find and eliminate these problems, you need to remember the basic concepts of the laws of electrical engineering, and have a car LED electrical circuit tester, tester or voltmeter. If there is neither one nor the other, then it is better to seek help from an auto electrician.

The situation is much simpler when one or more, but not all, backlights are off. Burnt out light bulbs are simply replaced with known good ones. From the practice of auto electricians, we can conclude that in most cases a fuse or light bulb blows. It rarely comes to troubleshooting using instruments, but sometimes it happens. You should be aware that if a replacement (new) fuse blows repeatedly, you should look for a short circuit in the electrical circuit.

In the second case, they do approximately the same, but take into account that there are no fuses for each indicator lamp. They try to replace the light bulb with a new one, if it doesn’t light up again, then the contacts need to be checked. As a rule, this is enough to troubleshoot problems. Otherwise, it is better to ask a specialist for help, because the sensor that works in conjunction with this warning lamp may be the culprit.
