VAZ 2115 instrument panel backlight does not work • AUTOVIBER.RU

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.

Hello! When you turn on the side lights, low beam, high beam, the panel is not illuminated (neither the priority panel, nor the sidebar/low beam key, nor the heater panel), but the green light is on (that the lights are working) and when the high beam is on, the blue light is on (that the high beam is on) . I looked through the book lengthwise and crosswise, then again diagonally, except for the electrical diagram of the panel itself, and how to fix a malfunction like “if the lamp does not light, then replace it,” I did not find anything. I rang the board, checked/replaced the light bulbs, what should I do? Maybe there is some kind of sensor? Or maybe it's the button? A cliff cannot form on its own.

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

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 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.

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.

Reasons why the PP stopped working

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

The instrument lights of VAZ 2114-13-15 do not light up

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 they stop working

all instruments on the panel. 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 order, but on a VAZ car2115

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 voltage of 12 V is not reflected at the terminals, then it is necessary to disassemble the mounting block and look for the cause of the problem.

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.

This fuse looks like, look, the dimensions on one side shouldn’t work either.

Experts' opinion

Ruslan. I sell various parts for tuning cars of the domestic automobile industry. Instrument panels that can be installed on VAZs appeared relatively recently, but have become very popular. This is due to the ease of installation and attractive design of ready-made solutions. Previously, craftsmen spent a lot of time just for one minor modification; now they can immediately change the interior design in an hour.

Michael. I installed a new instrument panel, which the seller had in the category for my car. The installation went very smoothly. I was really surprised how accurately the panel fell into place. There was no need to modify or change any parts. Therefore, I recommend exactly this method of changing the instrument panel: simple, fast, effective. The main thing is to choose the instrument panel correctly, otherwise there is a large choice, many low-quality options.

Why did the instrument panel illumination disappear on the VAZ-2114: does it not work and does not light up?

Recently it has become fashionable to install LED backlighting on the VAZ

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

will stop
working
. If you run the tester through the entire circuit, you can easily find an open circuit.

The most unpleasant and hardest-to-test element of a car is the wiring.

So, a broken wire can cause the dashboard lights to stop receiving power and therefore not light up.

In order to eliminate the problem, you need to test all the wires with a multimeter. which are responsible for illuminating the car’s dashboard. So, any, even insignificant, wire that breaks can cause the light in the dashboard to go out.

Another cause of malfunction can be oxidized wire pads.

Accordingly, there will be no contact, and not only will the lights in the instrument panel not light up, but they may also not work

other indicators that are located here. To fix the problem, you will have to disconnect the wire block on the fuse block and the parting panel itself. After this, clean the contact group and connect everything back. If everything worked, then the reason was found.

Dimensions work. But the license plate illumination, etc., the panel is not illuminated (or illuminated) and all the lights seem to be on low beam, high beam, etc. Maybe I just don’t know where this panel light is turned on)) like when the light is on. annoying at night. The panel is not visible, and you also know that the number is not illuminated (((So fuses?

Where do you get ideas for tuning?

Oddly enough, quite a lot of problems arise with finding an idea that will be implemented when tuning the dashboard. An example is that not everyone can create an instrument scale sticker.

Where can you get original ideas?

On the Internet you can find quite a lot of images of modifications to the instrument panel. It is these photographs that can be used as a reference point when creating your own dashboard.

You can also borrow design styles from other cars. For example, by taking an image of the dashboard of one of the foreign cars, you can make minor modifications and get an original design.

The backlight of the VAZ 2115 instrument panel does not light up

Replacing the fuse on a VAZ 2115

Each fuse that is included in the electrical circuit of the car must correspond to its rated current value, which thereby protects current consumers for a particular circuit from malfunction.

The instrument panel backlight does not work. Where to dig? Auto electrician advice.

To make it easier to find a fault both in the lighting and in other consumers, the manufacturer provides colors for the fuses. The schematic representation of the mounting block (Fig. 1) clearly shows the location of the fuses and relays included in the electrical circuit of the car.

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.

Why doesn't the instrument panel light come on?

I'll give you an example from my life. I went fishing in the summer with my friend in a VAZ car 2115

. On the way, before arriving at the place, the instrument panel lighting 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.

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.

Changing the dial design

Another fairly simple way to tune the instrument panel is to change the dial design.

For this:

1. The structure is dismantled and dismantled. 2. Purchase or create your own sticker that will be used to decorate the instrument panel. 3. Peel off the old dial and glue on the new one. 4. We assemble the structure and install it.

In addition to the dial, you can change the color of the hands. To do this, paint is applied using a spray can.

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 backlighting on the VAZ

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

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. The backlight turns on along with it.

devices. 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.

ONE OR MORE LIGHTS ARE NOT BURNING

The backlight of the VAZ 2114 instrument panel does not light up;
One or more warning lamps are not working.

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.

Dashboard lamps

The dashboard provides the driver with a lot of useful information that allows him to monitor the condition of the car, the driving process, diagnose breakdowns in a timely manner and correct them. So, the panel light comes on for the following reasons:

The battery is not charging.
For one reason or another, the handbrake is stuck.
Not enough fuel in the tank.
The oil pressure has decreased (which indicates the need to urgently stop the engine to avoid more serious consequences).
Excess water in the filter. To prevent water from entering the pump, which could lead to damage, you need to drain excess water from the filter.
The fuel system is malfunctioning.
There was a failure in the propulsion system and much more.

As you can see, the panel lamps allow you to determine what is wrong in the car; if the lamps themselves fail, then you can miss a very important breakdown, which can even lead to an accident. This is why it is so important not to delay replacement (the lamps cannot be repaired).

Today, the car market offers a wide range of lamps for the control panel, ranging from the standard version, which is cheaper but also has average characteristics, to modernized versions that give the panel, and therefore the entire atmosphere of the car, a different, more expressive atmosphere.

Professionals also advise replacing standard lamps with LEDs, which largely decorate the panel.

So, we list several of the currently most popular options suitable for the VAZ 2114.

LED lamps Sho-Me SM-T5 (blue, white and red). Country of origin: Korea, price: 80 rubles. for a couple.
High-brightness SMD LED module – 20 rubles.
LED Sho-me SM-T5-cap-super (white) – 50 rub.
Halogen lamps from Osram and Philips cost approximately 40-80 rubles apiece.

As you can see, prices for lamps are not high. It is worth noting that replacement takes very little time, which we will talk about later.

Solutions

So, when all the main reasons are, so to speak, “in the face,” you can try to determine the exact location of the breakdown, and also fix it yourself. As always, it is worth noting that if a motorist does not know the design of the car or is not confident in his abilities, then it is recommended to contact a specialist car service center.

Causes of malfunction

Where does the problem lie? As mentioned earlier, it is worth looking for problems in electrical circuits. Let's look at the main locations where problems may be hiding:

Fuse.
Backlight bulbs and their electrical circuit.
Wiring.
There is a fault in the fuse box.
Damage to the board.
