The dashboard of the VAZ 2106 does not work • AUTOINTERLINE.RU

Instructions for dismantling the instrument scale

From time to time, the owner of the “six” has the need to remove the panel, either to carry out repair work and replace individual devices, or to tune it and modify it to his own taste.
With all this, car enthusiasts often wonder how to remove the VAZ 2106 panel, because all the installation elements of the product are installed inconspicuously for others. But dismantling the element with your own hands is not particularly difficult, provided you follow the disassembly rules. Unscheduled panel removal requires a light set of plumbing tools, such as a screwdriver and wrenches. Dismantling of this set of control devices is carried out when a panel needs to be replaced, or when working with vehicle body components, during the dismantling of which it may be damaged.

Let's look at how to change the panel and at the same time keep its appearance constant. Disassembly activities are carried out in the following sequence:

We unscrew the fasteners of the device panel in the interior box and under the instrument panel.
We use a screwdriver to press out the radio plate with a certain degree of accuracy, so as not to break it. There are several bolts in the mounting housing of the audio system that need to be removed so that the mounting plate does not fall off.
We dismantle the radio panel.
We move the fasteners and disconnect the steering column decoration.
We carefully move the car clock from its place.
We mark the supply wiring, take out the backlight lamp from the chronometer and dismantle the watch.
We disconnect the contact of the interior box lighting and remove the shelf under the box, freeing it from the fasteners.
We remove the heater electric fan switch, mark its wiring, use a screwdriver to loosen the fasteners and remove the heating system shutter holders.
panel from its mounting points ; to do this, use a screwdriver to press it up and push it towards you.
Disconnect the cable of the speed measuring device.
We will definitely mark the wiring package for the next correct connection.
We disconnect the wire connectors and remove the dashboard, dismantling expensive decorations with the fasteners removed.
We are dismantling the instrument panel.

In practice, there are cases when panel 2106 does not light up and there can be many reasons. But you should always start with the fuse box. the panel does not work , then you should look at the fuse responsible for its functionality, and then move further according to the vehicle wiring diagram.

This car is also equipped with a rear panel, which is installed in the rear part and is equipped in the area of the wings and the trunk floor. It is equipped with rear view lights and side lights. to the crossbar of the rear panel of the VAZ 2106 .

"Six" instrument lighting control

To initiate and adjust the lighting mode of the instrument scale, a two-position VAZ 2106 instrument illumination controller is integrated into the lighting system, which operates in a low-current network of 12 V with a nominal current of 1.5 A and a weight of 50 g.

This product is an ordinary variable resistance resistor operating on the principle of a potentiometer. Only if in a potentiometer a change in resistance values occurs due to a change in the length of the switched-on section of the circuit, then here the change in this value occurs by changing the length of the coil, as a result of which the value of the rated voltage also changes.

However, in the “six” the instrument backlight most often does not light up due to the failure of this regulator, so the procedure for replacing it is as follows:

Disconnect the negative contact of the battery;
We pry off the retaining fasteners of the liner with a screwdriver and dismantle the dashboard;
In order to replace the instrument backlight regulator, disconnect the wiring and mark (if necessary) the wiring with a marker;
We dismantle the decorative handle of the device, simply pushing it in our direction, and using a key, first remove the fasteners, then the product;
Collect everything using the reverse algorithm principle.

How to repair or tune the instrument panel of a VAZ 2106

The standard dashboard of the VAZ 2106 is made in the form of a shaped metal product, the technological voids in which are filled with polyurethane foam made from PVC materials, and the frame of this electrical equipment complex is covered with a special moisture-proof film.

For movement and control of devices at night, this part is equipped with automotive instrument panel lighting, incl. each dial and instrument scales integrated into this electrical complex. A full description of the instrument panel can be found below.

On our Internet resource you can see a photo of the instrument panel of the VAZ 2106, where the instruments for monitoring systems and controlling the vehicle are located.

What kind of light bulbs are in the dashboard of the VAZ 2106

The standard illumination of the VAZ 2106 instruments, according to reviews from car owners, does not satisfy many of our compatriots who personally own this vehicle. There are very serious complaints about this electrical equipment unit - sometimes the light is dim, sometimes other problems arise in this component.

Sometimes there are cases when the instrument lighting on a VAZ 2106 car does not work for reasons related to other defects in the VAZ’s electrical equipment system. But the purpose of the backlight is precisely to make it easier to drive a car in conditions of poor visibility or at night.

It is in such conditions that monitoring instrument readings on the panel of auxiliary indicators located directly in front of the driver of the vehicle seems to be quite problematic, because visibility conditions do not allow this. Therefore, the illumination of the VAZ 2106 instrument scale plays an important role, especially with good brightness and luminous flux strength of electric light sources.

Installing the trim on the dashboard

2106 instrument panel on a VAZ 2101 does not require large expenses, with the exception of the necessary parts (electrical wiring for the necessary modification of the “six”, a sensor for measuring oil pressure, as well as a tee for connecting it). Installing the panel trim involves removing the dashboard from the car. This makes it possible to make its installation much better and in a shorter time. The following requirements must be met:

We degrease the mating surfaces very carefully.
After this, we wipe these surfaces with anti-silicone or its analogue, which is used when painting vehicles.
The adhesive solution specially used for this work must adhere tightly to the mating plane of the panel, which requires first cleaning the entire surface for gluing with sandpaper and fine abrasive. A surface that does not have a smooth structure glues both surfaces together better.
The preliminary stages of the technological operation will facilitate the application of primer to the plastic coating.
The primer mass must be spread in an even layer over the entire surface of the gluing area.
After this, wait a while for the treated surface to dry.
The PVC overlay on the panel can squeak if there is weak contact, so it is additionally necessary to secure it with self-tapping screws and additionally glue the surface.

2106 panel trim lies in its characteristics such as color and brightness. But increasing the operating temperature range is disastrous for this accessory; it can become deformed.

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.

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.

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.

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. Only if none of the actions allowed you to get rid of the breakdown, you can begin to replace the devices themselves. No options, the problem lies in them

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

The fuel level lamp is constantly on

If this lamp is constantly on, there is probably a short circuit in the fuel level sensor supply wiring to ground. Another option is that the sensor’s flexible bus is shorted to the fuel intake pipe. You will have to disassemble the device to align the bus and get rid of the resulting short circuit

Everything is gone or the 9th fuse!!!

Indicator lamps do not work on the dashboard

There is a high probability that the light bulbs have simply burned out, or they are poorly held in their seats due to loose contact. Replace the bulbs, but first try tightening the contacts. Traces of oxidation may be detected. When cleaned, the light bulbs can work normally again. Also, do not exclude the possibility of wiring breakage or oxidation of the tips of the supply wiring. Try going over the wires with a tester, cleaning the contacts if necessary.

The speedometer does not work, the flexible shaft is noisy

In such a situation, you will have to change the speedometer drive cable or replace the entire speedometer assembly. But before you bother so much, check that the fastening nuts of the tips are tightened correctly and properly. The flexible shaft may make noise during operation due to deformation or violation of the permissible bending of the shell of less than 10 centimeters during installation

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.

Tuning the illumination of the “six” devices

Typically, tuning the backlight of VAZ 2106 instruments is carried out in order to improve the driver’s perception of the parameters of the instrument panel indicators and to decorate the instrument panel.

Such work should be carried out independently, in order to avoid unnecessary financial costs and to implement your own version of the VAZ 2106 instrument lighting design, which will be a unique and unique project.

As an option for making the illumination of the VAZ instruments of the “sixth” model with your own hands, you can, together with replacing conventional light bulbs for lighting the instruments, retouch their instrument scales to bright colors that are dissonant with the color of the car’s dashboard. This color scheme includes neutral white, bright red and calm blue. The color can be chosen depending on the taste preferences of the vehicle driver.

If the car enthusiast has chosen the option of multi-color LED instrument lighting bulbs for the VAZ 2106, which are offered in seven colors, then an LED strip and a private control unit are installed, which is controlled remotely, and the light range can be changed daily or as needed.

Such an LED “garland” can be found in specialized retail outlets that sell products of this type. The price of such an LED chain of lights is low. All that remains is to select a color palette and start replacing.

Installation of such lighting for VAZ 2106 devices can be viewed in a video on our Internet portal.

The process of replacing instrument lighting itself is a simple operation, because the LED base is absolutely identical in size and mounting to ordinary lamps.

VAZ 2109 – troubleshooting instrument cluster

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 state 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.

READ VAZ 2106 petrol light does not light up

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.

VAZ 2106 INSTRUMENT PANEL DOES NOT WORK

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

Below is the electrical diagram of the instrument panel:

— Voltmeter.
— Instrument lighting lamps.
— Coolant temperature gauge.
— Warning lamp for heated rear window.
— Indicator lamp for high beam headlights.
— Backup warning lamp.
— Rear fog light indicator lamp.
— Indicator lamp for external lighting.
— Turn signal indicator lamp.
— STOP indicator lamp.
— Oil pressure warning lamp.
— Parking brake warning lamp.
— Hazard warning lamp.
— Brake fluid level warning lamp.
— Carburetor air damper warning lamp.
— Battery discharge warning lamp.
— Socket for the parking brake warning lamp relay interrupter.
— Fuel level indicator.
— Fuel reserve warning lamp.

Lighting devices and alarms do not work

The accumulated experience in operating VAZ cars has confirmed the high quality of almost all units and components and, as a rule, a car enthusiast who regularly and timely performs all preventive operations rarely finds himself face to face with the problems of “what happened to the car?” and “what should I do?”

Most often, on a long journey, devices and switches for these devices can remind you of yourself. Failure of lighting and alarm elements is very unpleasant, since such defects directly affect traffic safety. Considering that the causes of defects in most cases are elementary (burnt out lamps, fuses, etc.), it does not hurt the car enthusiast to get acquainted with methods for eliminating them.

The headlight bulb has burned out. As you probably guessed, in order to replace the lamp, the headlight must be disassembled. Using a screwdriver, unscrew the screw securing the facing rim and remove it, disengaging it from the bracket. Next, you need to loosen the screws securing the mounting rim, turn it counterclockwise and remove it together with the optical element.

To replace the lamp , release the mounting springs and remove the lamp. We must not forget that installing non-standard lamps can lead either to a weakening of the headlights or to rapid burnout of the lamp. The described process is performed when replacing headlight bulbs on VAZ 2101, 2102, 21011 . VAZ 2103 and 2106 cars is done somewhat differently:

Unscrew the screws securing the frame and remove the frame
slightly unscrew the screws securing the outer rim, turn it clockwise and remove
remove the optical element from the headlight housing and disconnect the plug block from the lamp
release the springs and remove the lamp from the optical element
Remove the plastic dust deflector from the lamp.

The headlight is assembled in the reverse order. When installing the lamp into the optical element, make sure that the protrusion on the rim of the lamp base fits into the groove of the optical element. To replace a burnt-out sidelight lamp, unscrew the two screws securing the lens to the body and remove the lamp from the socket.

Unlike sidelights and headlights, you do not need to remove the lens to replace a burnt-out turn signal (side) bulb. True, such “benefits” are provided only to owners of VAZ 2101, 2102, 21011, 2106 . The lamp is replaced from the inside of the wing after removing the protective rubber cap and socket included with the lamp.

VAZ 2103 models, similar work is performed only after removing the lens. Replacement of rear light bulbs is carried out after removing the lenses, which in most cases are attached to the inside of the trunk. If you have to change several light bulbs at the same time, make sure that each of them takes its “rightful” place.

Replacing failed license plate light bulbs is usually done from the underside of the bumper. To do this, you need to remove the rubber caps, and then the lamp socket.

The interior lamps of the body have lamps of 5 W each. To replace the lamps, you must remove the socket, held in the recess by two spring holders, after which you can remove the lamp from the spring contacts.

As you know, some VAZ car models are equipped with reverse lights and open front door alarm lights. It happens that the bulbs of these lanterns also fail. To replace burnt out lamps, you need to unscrew the screws securing the diffuser and replace them.

To replace the open front door alarm lamp, unscrew the screws, remove the housing with the socket from the case, disconnect the socket from the housing and remove the lamp from the socket.

The dashboard of the VAZ 2108 does not work

An electrical problem after disassembling and reassembling the dashboard, that is, dashboard and the jokes began. In general I describe the situation. I turn on the ignition and the fuel pump fires, but the instrument panel does not work and does not light up (nothing on the instrument panel lights up at all and the arrows are all dead).

And then it gets even more interesting. I turn off the ignition. And if you turn on the wipers, the starter starts to turn when the wipers are turned on, and if you blink the high beams, you hear the crackling sound of some relay and the instrument lights up (oil pressure, check, etc.). The tachometer needle starts jumping, and the fuel pump also works, VAZ 21099 injector

All instruments and sensors on the instrument panel have failed

After purchasing my VAZ 2106, literally a couple of days later, the following trouble awaited me. When the ignition was turned on, neither the emergency oil pressure light nor the battery charging came on, and the gasoline level sensor did not work. At first I thought that the battery terminal had simply come loose, but then I checked and everything turned out to be normal. Just in case, I decided to turn the starter, and as it turned out, everything worked, it turned and the car started up normally.

But even after this, none of the instruments and sensors worked; by the way, the tachometer also stood still and the needle did not budge. This was the picture with the ignition on and even the engine running, all the instruments froze tightly:

I decided to check all the fuses, since I simply could not see any other reason for what was happening. Since the location of the fuses in the mounting block of the VAZ 2106 was not familiar to me, I decided to check everything at random. I took the fuses out of the block one by one and inspected them.

It was already quite dark, and not at first glance all the veins on each fuse were intact. In the morning I checked everything again and saw that on one side, barely noticeable, the wire had burned out. The photo below shows the fuse that is responsible for the functionality of the sensors and devices of the VAZ 2106.

After I replaced it with a working one, all the sensors and arrows started working and everything fell into place.

So, if someone has a similar problem, or this is your first time encountering this, keep in mind that the fuse, which is shown in the middle photo in this article, is to blame. I hope that my experience will be at least useful to someone.

The instrument panel on the VAZ 2109 does not light up: do-it-yourself repairs, popular faults

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

malfunctions and methods for troubleshooting the instrument panel on a VAZ 2108, VAZ 2109, VAZ 21099

The tachometer underestimates or overestimates the readings

If the device is outright lying, then the problem most likely lies in the ignition system. In other words, it shows correctly, but the number of pulses created by the chopper per revolution of the distributor shaft is more or less than four. If the tachometer readings are incorrect, there is usually a deterioration in engine performance. In this case, the speed may fluctuate, misfires periodically appear, which is accompanied by engine vibration and white or bluish exhaust.

In this case, the fault should be looked for in the breaker, or rather, in its contact group or capacitor. To fix this problem you need to:

Disassemble the ignition distributor.
Check the condition of the breaker contacts.
Clean contacts.
Adjust the gaps between the contacts.
Check the serviceability of the capacitor installed in the breaker.
Check the serviceability of the crankshaft position sensor. In case of malfunction, replace it.

However, the reason may be in the tachometer itself. Malfunctions occur related to the parts of the electronic board, as well as to the milliammeter winding. You can't do without knowledge of electronics here.

The tachometer needle jumps chaotically

Jumps in the TX-193 needle in most cases are also a symptom of malfunctions associated with its electrical circuit. The reasons for this behavior of the device may be:

lack of good contact at the negative terminal of the battery;
oxidation or burning of the brown wire on the ignition coil;
burning or wear of the contacts of the ignition distributor cap or slider;
wear of the distributor shaft bearing;
shorting the red wire powering the device to vehicle ground;
malfunction of the crankshaft position sensor (for injection engines).

A similar problem is solved by stripping the contacts, replacing the ignition distributor cap, slider, support bearing, restoring the integrity of the insulation of the device’s supply wire, and replacing the crankshaft sensor.

Checking the correct operation of the tachometer

In a car service center, the accuracy of the tachometer readings is checked on a special stand that simulates the ignition system. The design of the stand includes a power source, a distributor and a counter of its shaft revolutions. The table below shows the calculated values of the distributor rotor speed and the corresponding tachometer readings.

Incompatibility of the TX-193 tachometer with a contactless ignition system

Older models of TX-193 devices are designed exclusively for contact ignition systems. All owners of “sixes” who independently converted their cars to a contactless system subsequently encountered problems with the tachometer. It's all about the different forms of electrical impulses arriving at the device from the breaker (in a contact system) and the switch (in a contactless system). The simplest way to solve this problem is to install a capacitor in the cut of the same brown wire coming from the breaker. But here it is necessary to experimentally select the desired container. Otherwise, the tachometer will lie. So, if you have no desire to engage in such experiments, just buy a device for a contactless ignition system.

Connecting a tachometer in injection VAZ 2106

In VAZ 2106 , equipped with engines with distributed injection, the connection diagram is slightly different. There is no breaker, no switch, no ignition coil. The device receives fully processed data from the electronic engine control unit (ECU). The latter, in turn, reads information about the number of crankshaft revolutions from a special sensor. Here the tachometer is connected to the power circuit through the ignition switch, the vehicle ground, the computer and the crankshaft position sensor.

Why does the VAZ 2108 tachometer not work? VAZ 2108 tachometer malfunctions

Each car has its own dashboard . They all differ in style and design, but what they all have in common is that they all show the same data. As a rule, this is data on the engine temperature, fuel level in the tank, vehicle speed (speedometer), and the number of engine revolutions per minute (tachometer).

Today we will talk about tachometer malfunctions. You will learn why the tachometer does not work, as well as about the main malfunctions of the VAZ tachometer.

What is a tachometer and why is it needed?

A tachometer is a device that, as I already said, shows the number of engine revolutions per minute (thousand rpm). The tachometer readings are necessary to make it easier for the driver (usually a beginner) to navigate and correctly select the desired gear (up or down). A tachometer is also necessary in order to monitor the correct operation of the engine by the number of revolutions. For example, when the speed fluctuates or is too high, a fault can be detected in time.

The first tachometers were analog (they are also called dial gauges). Analog tachometers have a dial with numbers and an arrow. One division of the analog tachometer is equal to 1 thousand revolutions. A little later, digital (electronic) tachometers began to appear on mostly Western-made cars. Data in electronic tachometers is displayed on a display (LCD or LCD display). In modern cars, digital tachometers look like analog ones because, like older tachometer models, they display information in the form of a dial and an arrow that indicates the number of revolutions.

VAZ tachometer does not work - common reasons

In conclusion, I would like to note that the reasons and diagnostic methods described above are superficial and the most common. It is possible to study the issue in more detail and understand why the tachometer does not work or why the tachometer needle twitches only with special equipment. Therefore, if it is impossible to independently diagnose a tachometer malfunction, I recommend turning to specialists at a service station for help.
