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.

Why doesn't it light up?

If suddenly electrical appliances and indicator lamps on the dashboard stop working, certain actions must be taken.

1. First, remove the cover of the mounting block and make sure that the fuse is intact. The fuse markings are located on the inner surface of the cover. You should look for fuse F16 or F5, depending on the year of manufacture of your VAZ 2109.
2. If the fuse is intact, be sure to check whether the contacts of the fuse you are looking for have not oxidized. It is not uncommon for shields to fail due to broken contact.

If none of the above actions yielded results, you will have to be disappointed. After all, now you need to remove the dashboard and check the condition of the wiring, contacts, and negative connections. Here it is better to trust a professional electrician or set aside a whole day to troubleshoot problems yourself. There is no need to rush here.

Where did the backlight go?

If we talk about the dashboard of VAZ 2109 cars, then they are characterized by certain problems. We will tell you about them, and also tell you how to act correctly in a given situation.

Gasoline level and temperature indicator does not work

In most percent of cases, this situation occurs due to breakdown of devices, sensors of these devices, or an open circuit of the power supply. Therefore, first check the circuit for continuity, make sure that the fuses have not blown. If this is not the case, check whether the gas level and temperature sensors are working.

When the fuel tank is full, the arrow points to zero

If you have worked on the fuel level sensor, the fault most likely lies with you. When manipulating this device, the float limiter is often knocked down. Either the limiter is installed incorrectly or adjusted, causing the resistor winding to end. To resolve the problem, remove the sensor and then adjust the limiter again

The fuel gauge needle regularly jumps and ends up at zero

Here, most likely, the resistor has weak contact with the current collector. Another possible option is that there is a break in the resistor. To resolve this situation, we recommend replacing the hot level sensor with a new measuring device

Panel tuning options

If you decide to tune your instrument panel, then most likely you will be interested in knowing what options exist for doing it. The tuning shield, as you know, pleases the driver’s eye, so this issue is relevant for many car owners.

Dismantling the shield

To tune the dashboard, you first need to remove the device itself.

To do this, you only need to disconnect eight fasteners; to do this, you can use a regular knife:

• First, the fastenings on the driver’s side are disconnected;
• then you need to release the latches located there, on top;
• after this you can disconnect the middle part of the tidy;
• the panel itself is dismantled (the author of the video is Artem Volivach).

To perform backlight tuning on a VAZ 2109, the lighting sources must be replaced after removal; in this case, it is advisable to use diode bulbs, and if necessary, the scale itself can be modified.

The tuning procedure includes the following steps:

1. First, dismantle the standard insert where the scales are located. Remove all the arrows and set them aside, then make corresponding holes for them in the new pads. To prevent the arrows from sticking when operating the instruments, the holes can be made wider.
2. Next, you need to remove all the standard lighting sources - just dismantle the entire circuit and install diode devices instead of the old light bulbs. When installing new sources, observe the polarity, since if it is confused, this will lead to the inoperability of the device as a whole.
3. Once the lamps are installed, you can begin to refine the scales. Take the new pads and, using fluorescent paint or a marker, paint the numbers on the scales. Such a marker or paint will be required so that when the instrument is illuminated with LEDs, the numbers glow more brightly and stand out.
4. After the backlight tuning is completed, you will need to carefully install the circuit and install new overlays on top of it. When installing, be careful not to damage the panel elements.

Replacing dashboard light bulbs

The first and quite logical problem due to which the instrument lights do not light up is the failure of all or just a few light bulbs at once. In this case, the only solution would be to replace them. It is performed as follows:

• The most difficult task will be dismantling the entire dashboard, which, unfortunately, is necessary to install new lamps. This, in turn, requires disconnecting all electrical connectors, the econometric hose and disconnecting the speedometer cable. You will also have to remove an additional panel, under which there are connectors for the cigarette lighter and the lighting system;
• we unscrew the failed control and illumination lamps;
• We install new products that are selected according to the characteristics specified in the vehicle specification.

If you intend to replace the torpedo backlight bulbs, you should know that there are only four of them. They are located in pairs at the top and bottom of the dashboard. In addition, control indicators are located under it, which allow you to see:

• fuel and battery charge level;
• indication of the inclusion of high beams and side lights, activation of the handbrake;
• indication of turn signal activation;
• lubricant pressure in the engine.

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.

Why doesn't it light up?

The instrument cluster installed on a VAZ 2109 car is a panel built into the dashboard on the driver’s side and includes a set of various instruments necessary to monitor the current condition of the car. This includes devices for monitoring oil pressure, engine speed, driving speed, as well as a number of indicator lights that indicate the operation or malfunction of certain vehicle systems.

In this article, we will look at popular faults and how to fix them.

• The temperature and fuel level indicator does not work.

In most cases, the reason for this may be either a malfunction of the devices themselves, their sensors, or an open circuit in their power supply. Therefore, to eliminate the defect, first of all it is worth ringing the circuit and checking the fuses. Then we check the functionality of the temperature and fuel level control sensors. And only then, if the above reasons are not identified, replace the devices themselves.

• The fuel tank is full and the needle returns to the beginning of the scale.

If any manipulations have been made with the fuel level sensor, it is necessary to check whether the float limiter has been knocked down or incorrectly installed/adjusted and, as a result, the resistor winding has ended. To resolve this problem, remove the sensor and then readjust the limiter.

• The fuel level needle constantly jumps and often falls to about.

In most cases, the problem lies in the weak contact of the resistor with the current collector. Or there was a complete break in the resistor. To fix the problem, replace the fuel level sensor.

• The fuel level lamp is constantly on.

The sensor supply wire has shorted to ground. Or a short circuit between the flexible sensor bus and the fuel intake pipe. Disassembly is required to straighten the busbar and eliminate the short circuit.

• The indicator lights on the instrument panel do not work.

Perhaps they have burned out or their fastening in their mounting sockets has become loose. Replace the lamps or tighten the contacts; they may also oxidize and need to be cleaned. A break in the wires or oxidation of their tips. Test the wiring with a tester and clean the contacts if necessary.

• The speedometer does not work, there is noise from the flexible shaft.

Replace the drive cable or the speedometer itself. Having previously checked the quality of tightening of the lug nuts. The reason for the presence of noise during operation is either deformation of the flexible shaft or when, during its installation, bending radii of the shell were less than 10 cm.

This completes the review of common faults and methods for eliminating the instrument cluster on a VAZ 2109 car.

Instrument panel lighting for VAZ 2109

The backlighting of the VAZ 2109 instrument panel is often not satisfactory for drivers. You can change the color and its brightness yourself, without turning to the salon for help.

To improve the lighting, you need to install LEDs instead of conventional incandescent light bulbs. Their glow is much brighter, in addition, you can choose the color of the backlight at your discretion: blue, green, red or white. These are the main colors, but if you look, you can also find purple LEDs.

Replacement of light bulbs or sockets must be carried out carefully and carefully. If the car owner decides to use LEDs to illuminate the buttons, then you need to purchase a light bulb with a regular base. Soldering and a special cartridge are needed if there is a desire to replace the backlight of the instrument cluster. Among the many LEDs, there are also those that have a diffuse or, conversely, point glow.

These effects are achieved using a focusing lens configuration. A more uniform backlight is suitable for illuminating the scale on the instrument panel, and a brighter light is suitable for the button icon. Every driver should take into account the features of design changes when improving his car.

Instrument control panel illumination

When carrying out tuning inside the car, some drivers purchase the necessary parts in specialized stores or make them themselves. When redesigning the lamp design, you need to maintain the original dimensions so that you can easily replace them with the original ones. Usually they light up the control panel for the stove and appliances. Some designers use backlighting for a voltmeter, clock, or oil pressure indicator.

To illuminate the stove, you first need to carefully remove the plastic handles of the levers that control the dampers and remove the glass. Below it is the stove itself. To do this, take any sharp object (knife or scissors) and carefully pry the glass. Prepare foil according to its size. It will be an additional source of illumination.

Fixed on the inside of the glass, it will give a very attractive appearance to the stove, and the console illumination will not be concentrated only in the place where the LED is installed next to the handle.

The next step is to remove the lamp socket from the backlight of the stove control unit. The lamp must be replaced with a purchased LED. In order for the light to spread around the entire perimeter of the stove, an LED strip is used, which is glued to the bottom. Two wires are usually soldered to the contacts, which are connected to the cartridge.

All connections are carefully insulated. Assembly is carried out in reverse order. If one of the parts does not work, check all contacts and connections again. The lighting of the stove control panel will become much better and more modern; the light from it will spread throughout the entire perimeter both day and night.

Features of backlight replacement

How to change the panel, making it a designer one? You need to be extremely careful and precise when removing and disassembling the dashboard, so as not to subsequently disturb the correctness of its readings. Often, during disassembly, the chrome plating of parts suffers. So be patient and get to work.

First, remove the dashboard panel. You can read about how to change it in the repair instructions for your car brand. Then remove the instrument cluster, disconnect the plugs, bend the speedometer cable and replace the bulbs. Gradually remove the filters from the buttons. It is better to leave the green-blue light spectrum on the panel unchanged, but replace the green filters completely.

You can make the rear window heating button illuminated orange, and the fog lamp button illuminated turquoise. This shade can be achieved by passing the white color of the LED through a green filter. The reflector can be foil secured with double-sided tape. The hazard warning lights should be red (like in foreign cars). In this case, maintaining polarity is of particular importance.

In a ring filter, using a file, you can make triangular slits through which the light will be scattered. The overall illumination pattern will become more uniform. It's time to check the performance of the LEDs. Only after this check can a constant voltage of 12 V be supplied.

Instrument needles are often replaced with special ones with backlight. This effect is achieved by a lamp located near the axis. Every driver who has basic knowledge of car mechanics and puts in a little effort can boast of a beautiful dashboard. Improve the design of the VAZ 2109 and enjoy it!

general information

VAZ 2109 electrical faults

Let's start with general information. You should know that the VAZ 2109 has two power sources - the battery and the generator. The battery is designed to supply current when starting the power unit of a car, as well as to power the starter and other 12 V consumers when the engine is not running. When the engine starts, all the “initiative” goes to the generator. Now this element provides current to all consumers, even the ignition system and battery.

Popular faults

If we talk about the dashboard of VAZ 2109 cars, then they are characterized by certain problems. We will tell you about them, and also tell you how to act correctly in a given situation.

The instrument panel of the VAZ 2109 is not so complicated that you cannot figure it out on your own. But in the absence of experience, it is better to entrust the repair to specialists, or to enlist the support of a partner who understands this matter.

Tips for motorists

There can be at least three options for instrument panels installed on a VAZ 2109 car. The first combination of the instrument panel is placed on those “nines” where there is a low front panel. The second instrument panel combination is installed on “nines” with a high front panel. And the last third instrument panel combination, which is already electronic, is installed on “nines” with a “European panel”.

On instrument panels that are placed on a low panel in VAZ-2109 cars, there will most likely not be an option with a complete failure of the entire instrument panel. Since on these panels, the speedometer and econometer are mechanically driven, and the likelihood that they will fail together with electrical devices and warning lamps is very small. There is no econometer on the high-panel instrument panel, but the speedometer also has a mechanical cable drive.

If all electrical devices and warning lamps on all three versions of the dashboards stop working, then first of all you need to open the hood, then unfasten the cover of the mounting block and see if the fuse through which power is supplied to the instrument panel is intact. The fuse markings are located on the inside of the mounting block cover.

If the fuse is intact and its contacts are not oxidized, then next you need to see if power is supplied to the instrument panel. This can be done using a control lamp with the ignition on. Disconnect connector X4 on the mounting block and check whether there is voltage at pin No. 3. The fact is that the mounting block on the nines will always be wet during rain, it’s not for nothing that drivers call this place a swamp, and because of this, oxidation of the contacts in the pads often occurs, which leads to electrical failures. Sometimes not only the contacts, but also the circuit board of the mounting block oxidize.

If the driver was unable to find a fault in the above mentioned places, he will have to remove the instrument panel and check the condition of the contacts in the two blocks, as well as the reliability of the connection of the ground wire, but this is already more painstaking work.

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 diagonally, except for the electrical diagram of the panel itself, and how to fix a problem 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.

Common instrument panel faults

The instrument cluster on the VAZ 21099 or 2109 is a fairly reliable unit. However, even this can fail over time.

The main malfunctions characteristic of the VAZ instrument panel:

1. The lights on the instrument panel of the VAZ 2109 stopped lighting. If only a few light bulbs refuse to work, then most likely the reason lies in their burnout. If the instrument panel lighting stops working completely, then most likely the problem is a poor power supply. As practice shows, power problems are usually caused by either damaged wiring or oxidation of contacts at connections and connectors. If this is the case and the backlight does not light up due to oxidation, then you can get rid of this problem by cleaning the contacts or replacing them. If the problem lies in the lighting sources, then replacing the lamps will solve it.
2. Another problem, oxidation on the circuit board, is common in older vehicles or vehicles with moisture present. Due to oxidation of the board, the backlight and some instruments may not work, in particular, fuel level and coolant temperature controllers, tachometer, etc. If the needles do not rise on the tachometer, speedometer, fuel consumption sensor and generator voltage, or they work chaotically, then you need to carry out a full check of the dashboard.
3. VAZ 2109 cars are characterized by the problem of a non-working speedometer. As a rule, it appears as a result of wear of the cable connected to the box, or due to repairs to the device and its incorrect connection. If the cable is worn out, then you just need to replace it, there is nothing complicated about it. The main thing is to connect the cable correctly so that its tip fits exactly into the groove on the tidy speedometer.
4. Damage to the board itself. Such a malfunction occurs quite rarely, but, nevertheless, it should not be forgotten. If the structural board fails, the shield will have to be repaired, but if this does not help, then it will need to be replaced.
