Digital: how VAZ developed digital devices, and why it all failed

The instrument panel on VAZ 2109 models is equipped with multiple icons and indicators that indicate the status of various car systems. But the owners of “nines” do not always know how all these indicators are deciphered and what functions they perform. In this material we will tell you everything a 2109 car owner needs to know about the dashboard of his car.

Designation of icons on the VAZ 2109 dashboard

The indicator panel can be divided into 2 parts. The smaller half of the bulbs are mounted centrally at the top of the board. There are indicators on the bottom line of the instrument panel.

1. The meaning of the light is simple - the indicator indicates that self-monitoring diagnostics of the alarms are being performed.
2. Indicates that there are problems in the power plant. If the lamp is constantly on, you need to diagnose the motor.
3. The brake system is in disrepair. Usually the light indicates a drop in fluid in the expansion tank or critical wear of the pads.
4. Coolant level sensor lamp. If it lights up constantly, you need to add antifreeze to the system.
5. The windshield washer fluid has run out.
6. External lighting lamps are damaged. The thread may have burned out or the contact may have broken.
7. The front brake pads are worn to the limit.
8. The oil level in the engine crankcase has dropped. It may also indirectly indicate a malfunction of the oil pump.

The photo below shows the sequence of light bulbs at the bottom of the dashboard.

What do the buttons on the panel mean?

Depending on the configuration and year of the car, 2 types of devices can be installed here. The keys and controls will vary.

Below is a description of the low tidy indicators.

Next there is a decoding of the controls of a more modern - high panel.

Installation and repair instructions

If you are faced with the problem of a failure of the dashboard of a VAZ 2109 vehicle, then the best option would be to replace the dashboard yourself. To properly replace, you will need instructions for dismantling and installing the shield, which are given below. To perform these steps, you only need screwdrivers - flat-head and Phillips-head. The instructions are given on the example of a low panel, but in general they are identical for other versions of instrument panels. Don't forget to disconnect the battery!

1. First of all, you need to de-energize the system; to do this, disconnect the terminals from the battery.
2. Using a Phillips screwdriver, unscrew the plastic trim around the steering wheel. You don’t have to remove it, but it is advisable to do so for greater convenience.
3. You can also disconnect the steering column switches by simply unplugging the wiring harness.
4. Using a Phillips screwdriver, unscrew the two small screws securing the dashboard visor and remove this element.
5. After these steps, you can compress the springs and remove the electronic panel from the center console.
6. The next step is to disconnect the speedometer cable. It is necessary to be very careful when dismantling so as not to damage the cable, especially if it is old. Otherwise, it will need to be replaced.
7. Next, turn off the white outlet and remove the econometer hose.
8. Then you should disconnect the cable for resetting the car’s daily mileage data from the speedometer.
9. The final step will be to disconnect the red connector and dismantle the shield itself. A new panel is replaced and installed, after which further assembly is carried out in the reverse order.

As you can see, the procedure for replacing the instrument panel is not particularly complicated - just do everything in accordance with the instructions and there will be no problems in the further operation of the device.

Tidy 21099 injector: icon designations

There are more lights and indicators here than on the carburetor. Additional light bulbs available:

• requirement to check the engine;
• STOP light.

Tidy 21099 carburetor: designations

The decoding described at the beginning of the article can be fully used as an example for this point.

Stop light on the dash 2109

The lamp signals the driver about the presence of unexpected problems in the on-board circuits. When such an inscription is activated on the device, it is recommended to immediately go to a service station and look for the cause.

Fuel level sensor

Especially for those car owners who want to see accurate data and are looking for a suitable type of sensor, we offer a table for your reference:

The optimal choice would be the sensor number 2108-3827010-01. Its reading is approximately as follows: the middle of the scale indicates a level of 20 liters, and the red zone begins when the tank contains about 5 liters of fuel.

In any case, when you buy a sensor, test it for resistance: the best option for you is a sensor that shows 360 ohms when the tank is empty.

High and low panel VAZ 2109 - the difference

Depending on the year and modification of the car, two types of devices are applicable. The first is considered a low panel, used mainly on carburetor nines and modifications with an injector.

A more advanced version was brought to market in the last years of production. Here there are all the symbols used initially and several indicators of the engine fuel injection system have been added. The dashboard looks more modern, which makes it attractive to car enthusiasts.

The evolution of dashboards for AvtoVAZ products, part 1 Classic

It was used by cars 2101 and 2102, as well as their derivatives. The next model (VAZ 2103) did not receive the old panel, but it received a second life on the Oka

With the advent of a new family of cars, a new look at the combination has appeared

The number of instruments increased, everything that was rectangular became round, the shape of the dashboard itself was new and later appeared on another 2106, but this stylistic arrangement of dials was no longer used

Another experiment with quantity and design, released a little later, the VAZ 2107 was very different from this version

The 2107 existed with such a panel until the end (at the end of its life the VAZ 2104 received the same devices)

Initially, NIVA received devices from 2106, but its own arrangement

plus various games with colors and fonts, the corporate orange color reached it too, digitization was made radial.

Chevrolet Niva has received its own style. And there are devices that are inscribed “wells”

Well, just the other day Niva underwent another modernization and received new devices

Errors on the panel

VAZ versions of on-board computers have a self-diagnosis option, which allows you to read codes yourself without the use of additional equipment. The following is a list of common problems encountered on cars.

Instrument panel lamps VAZ 2108, 2109, 21099

On the instrument cluster of the front panel of VAZ 2108, 2109, 21099 cars there is a large number of different indicator lamps and signaling devices. Let's look at their icons, descriptions and purposes.

Possible faults

What malfunctions are typical for the dashboards of VAZ cars? Check out the main list after watching a video about connecting the shield from a VAZ 2110 to a “nine” (the author of the video is Garage BFS).

1. The speedometer does not work. There may be several reasons for this - a broken cable, its incorrect installation or wear of the socket. You should try disconnecting the cable and reconnecting it.
2. The odometer, which records the mileage of the vehicle, does not work. This problem is usually resolved by replacing the device.
3. One or another indicator does not light up. Perhaps the sensor itself has failed or the light bulb has burned out.
4. The instrument panel backlight does not work. This is usually due to burnt out bulbs or bad contacts. There may also be problems in the electrical circuit, but this happens rarely.
5. The coolant or oil level sensor is giving incorrect information. For example, the driver is warned about a lack of engine fluid level or boiling refrigerant in the expansion tank, but in fact, with these parameters everything is normal. The problem is usually solved by replacing the sensors.
