When the instrument panel on a VAZ 2109 does not light up, this is one of the common malfunctions of this unit. To fix a problem, you first have to find the cause of its occurrence.

Tidying up nine

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.

What does it mean?

Now many owners of iron horses already know what a small yellow or orange light bulb of a characteristic shape on the dashboard means. If translated literally, check engine sounds like “check the engine.” Therefore, it should warn the driver about malfunctions of the motor unit. That is, the computer on board detected some kind of malfunction in the operation of this compartment.

Normally, when you start your car, this light goes out immediately when you start the engine. And when the key is inserted into the ignition, but the engine is not started, it should light up. But sometimes just the opposite happens. And if this factor bothers you when operating the machine, then this is one of the signals that something needs to be done.

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.

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.

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 problem may be caused by a ground wire

Sometimes situations arise when the needles on instruments behave completely inappropriately, jumping sharply from the minimum to the maximum mark and vice versa. In the vast majority of cases, the cause of this malfunction is the lack of normal contact with ground. There is nothing difficult in fixing this problem. First of all, you should find the fastening of the ground wire connecting the instrument panel to the partition that separates the interior from the engine compartment. It can be detected by removing the car radio from its standard socket.

However, there is one caveat here. If an alarm was installed on the car, then the fastening of the mass wire could well be moved to some other place. However, as a rule, the car owner is warned about such actions. In most cases, the fastening of the mass wire is moved to the area where the driver’s left foot is located, placing it behind the interior trim.

By the way, a situation where the arrows on the instruments begin to “jump” can also arise after installing the radio. In order to do this, you need to unscrew the ground wire coming from the dashboard. It happens that it is then screwed in poorly, and subsequently, due to body vibration, the contact becomes unreliable. To solve the problem, just twist the wire normally. It is worth noting that doing this is not very convenient, so you will have to make some effort.

The cigarette lighter is another possible cause of instrument panel failure. Often various additional devices are connected here. At the same time, many consumers require high current, and because of this, either fuse F19 blows or the cigarette lighter itself fails. The check in this case will be quite simple, provided that the fuse has not burned out, you need to disconnect the cigarette lighter connector.

If this is not the problem, then you will have to look for the cause directly in the instrument panel. It should be pulled out from its standard mounting location as far as possible, but do not disconnect the wires going to the pads. Next, we measure the voltage at the contacts indicated in the diagrams by numbers 6, 9 and 10. Everywhere there should be the same indicator - 12 volts. In addition, you should also check the ground wire on block X1 (white). Also inspect for possible damage to the tracks on the back of the instrument panel that supply electricity to the appropriate consumers.

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.

Types of panels

Instrument panels on the VAZ 2109 are of at least three types:

Low panel;
High panel;
Electronic panel on nines with Europanel.

Europanel

On versions with a low panel, failure of the entire panel is extremely rare. This is due to the fact that here the speedometer and econometer are equipped with mechanical drives. Therefore, it is unlikely that they will fail along with the electrical component.

Dashboards with a high panel do not have an econometer, but the speedometer is also based on a mechanical cable drive.

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.

The regulator turned on the drum. I'll look at the fuse, but it's doubtful that there should be a separate fuse for the backlight (the dimensions and light work). It looks like some kind of chip has fallen off, because... it happened on a small hummock.

So it most likely came off the regulator; there is no separate fuse for this. The interior light and license plate light are on the same fuse.

While driving, the lights on the instrument panel and heater controls dimmed. Dimensions, near, far - everything shines. The indicators on the instrument panel light up. Where could something have fallen off? I don't have the manual at hand, what kind of fuse or connector can I use? Thank you in advance.

The same thing happened to me recently. The problem turned out to be a double button for turning on the headlights/low beam, poor contact. Replaced under warranty - everything is ok. Try it, maybe it will help.

Functionality check

After completing the replacement, install the panel inside the car, connect the connectors, but do not rush into final fixation - you still need to make sure that everything works properly.

To do this, turn on the ignition and see if the backlight turns on. Then check whether the indicator lights responsible for:

hand brake;
oil pressure;
fault signal, etc.

Then test the turn signals, headlights and side lights. If everything is in order, then complete the panel assembly.

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 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.

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;

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.

Fuse

There are fuses in the lighting circuit. The lamp is activated and voltage is supplied to the lighting lamp only if the fuse is working properly. In different years of model production, two different types of mounting blocks were installed on the car from the factory. Note the location of the dome light fuse on each of them. First, let's look at the location of the fuse in the mounting block of the new model. This element is also responsible for the operation of the brake light.

In the old-style mounting block, this element is located a little differently - it is the 7th in a row from left to right. The power of the element in this version of the block is 10 Amperes. In addition to interior lighting, a circuit to the brake light goes through this element. This may help when trying to diagnose a malfunctioning ceiling light.

If, after replacing a burnt-out part, the light in the interior of the VAZ 2114 does not come on, you should look for the reason in the wiring and the light bulb.

Hard case

The contacts on the ignition switch are burnt

What do they check on the road?

In the Traffic Rules, the list of faults for which driving is prohibited is relatively short:

failure of the service brake system
steering failure
headlights and tail lights not working in the dark or when visibility is poor
The driver's side windshield wiper does not work in rain or snow.

You still cannot tow a trailer if the towbar is faulty.

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.

Fuse box tracks burnt out

In a situation where the device “blinks” and periodically turns off completely, you should check the condition of the tracks in the fuse box. A short circuit, moisture and dirt getting into the block body - all this can lead to breakdowns on the tracks. The photo below shows a typical picture of a faulty fuse box in the “four”.

Because the price of a new block board exceeds 2000-3000 rubles; it is much more profitable to try to re-solder the tracks yourself. This problem is not critical, so if you have the skills to use a soldering iron, you can restore damaged tracks. For prevention, you can treat all contacts to remove oxides and dirt. It is also possible to treat contacts with dielectric grease.

If one of the lighting bulbs blinks, check the reliability of its contact. When driving on a bad road, the contacts in the device may come loose. The introduction of new lighting elements instead of standard ones is an intervention in the design. If new diode lamps are installed incorrectly, problems may occur with other components of the panel. Of the problems listed in the article, the “easiest” one is a blown fuse, while the most undesirable one is a malfunction of the board and mounting block. In any case, the availability of new and used spare parts for the “four” makes this problem insignificant.
