VAZ 2112 dashboard: description of symbols and lights

The instrumentation of the VAZ 2110 has remained virtually unchanged. The board displays basic information about the status of on-board systems to the driver in real time. Depending on the configuration, the old-style dashboard has a simplified design than the versions on new cars. The differences in configurations are also minimal. Cars with engines with 8 valves or 16 are identical. The only difference will be on engines such as injector or carburetor.

The most common “tens” device has only 19 indicators and gauges. Each element is responsible for its own part of the on-board equipment.

Designation of icons on the dashboard of Lada 2112

For a better understanding of the purpose of the indicators, their interpretation is given.

Number in photo	Interpretation of lamps and indicators
1	Coolant temperature indicator; if the light comes on at the top of the scale, the engine has overheated.
3/4	The turn signal indicators light up simultaneously when the hazard lights are turned on.
7	Empty tank indicator; if the lamp lights up, stop at a gas station.
8	External lighting is turned on and operating normally.
9	The pressure in the brake system has dropped. It is necessary to immediately add fluid to the expansion tank of the system.
10	The high beam headlights are activated.
12	The odometer display shows non-resettable mileage.
13	The hazard warning lights are on.
14	The engine control system is damaged or not working correctly.
15	The battery is not receiving a charge. In this case, you should check the battery itself for wear and the generator set.
16	The handbrake is activated.
17	The oil pressure in the engine crankcase has dropped below normal. You should add fluid to the specified level and check the operation of the pump.
18	In a configuration with an airbag, it indicates that the squib drive is turned off. In other versions the light bulb is a backup one.

Ideas for tuning and modifying the shield

How can you improve the tidy in the “Ten”:

1. By installing a new trim on the console. This type of tuning is the simplest, since you just need to install a trim on top. However, it will not improve the dashboard itself in any way, only its upper part.
2. In the VAZ 2110 you can install a dashboard from Priora; in general, the selection of tuned, ready-to-use dashboards is quite large. When installing a device in 2110 from another car, you will have to partially redo some connectors and connect new devices. But in general there is nothing difficult about this.
3. Installation of new scales on sensors. Scales can be downloaded from the Internet, found in a store, or developed independently. The alteration procedure in this case will be more complicated - you will have to remove the shield and disconnect the arrows from the instruments, this will take time. After installing the new scales, the arrows must be correctly installed, otherwise the speedometer and other sensors may malfunction.
4. Installation of LED lighting in the tidy. You can simply replace standard light bulbs with LED ones, or purchase a diode strip and solder it into the shield. But keep in mind that if the light bulb fails, it can be replaced without any problems, which cannot be said about the LED strip. If it burns out, you will have to unsolder the tape and install a new one in its place. Although the service life of the LED strip is quite long.
5. If you install diode lamps, then you can additionally paint the numbers on the scales, as well as the arrows of the sensors, with fluorescent paint. The fact is that combining these two types of tuning will allow you to achieve a truly high-quality and beautiful result. Under LED lighting, arrows painted with luminescent paint will glow much brighter.

Indication symbols

As you know, all the lights on the control panel come on when the ignition is turned on, and then, when the engine is already running, most of them go out. But when one remains on or blinks, this cannot but be alarming, because not everyone can immediately figure out what malfunctions this indicates, which of the systems needs urgent repairs.

Let's look at the designations of the instrument panel of the VAZ 2110. You should know that regardless of whether the panel is new or old on your car, the designations are almost the same, but the indicators may be located slightly differently.

Errors on the dashboard 2112

VAZ cars have always stood out for their ease of operation and maintenance. Regardless of the type of engine, injector or carburetor, here the user can independently perform diagnostics and read errors without additional equipment. Symbols may appear on the instrument panel.

Number	Meaning
2	Critical voltage drops have been detected in the on-board network.
3	The gasoline level sensor is damaged or does not work correctly.
4	Likewise for the antifreeze temperature sensor.
5	The outdoor thermometer is faulty.
6	There is critical engine overheating. You need to stop and let the engine cool.
7	The oil pressure in the engine is insufficient for normal operation.
8	The brake expansion tank is empty and needs to be topped up.
9	The battery is not charging properly. You will need to check the generator and its wiring.
E	BC firmware is damaged.

Most two-digit codes are a combination of two errors.

Instrument panel layout of VAZ 2110

The instrument panel of the VAZ 2110 is made in the form of a combination of instruments, indicator lamps, and in some modifications with the ability to accommodate an on-board computer. Traditionally, the plastic from which the panel is made is not of the highest quality, therefore, during operation and overheating, its deformation is possible, affecting not so much the appearance as the performance of the devices.

The standard tidy includes four dial gauges, a trip computer display, an odometer reset button and a set of warning lights. The first on the list, the leftmost device is the coolant temperature indicator, it is shown in the diagram under the first number. The pointer device has a division value of approximately 50 degrees. The red stripe marks the zone of critically high temperature at which the coolant may boil. The additional panel contains control lights and an indication of the climate system.

The VAZ 2112 instrument panel does not work - reasons

If the panel suddenly stops working:

1. When the engine does not start and the dash does not work, inspect the ignition switch. Here the contact often burns out or oxidizes.
2. If the machine is working and the panel has failed, you will need to check the corresponding fuse, wiring and lines.
3. If the manipulations do not help, you will need to remove the device and test its circuits.

Panel backlight does not light up

There may be damage to the light activation key. It is recommended to check the corresponding fuse.

The panel is blinking

Consequence of deterioration of electrical wiring contacts. The user should inspect the supply wires for cracking or damaged insulation. The contact groups should be disconnected and cleaned of oxides and dirt. Treat the terminals with special oil.

Tidy 2112 stuck

This kind of problem is unexpected, but it occurs everywhere. As a repair, users are suggested to reset the electronic equipment. Remove the terminals from the battery and wait 15 minutes.

Possible malfunctions: signs and causes

What problems can a car owner encounter:

1. Some of the light bulbs on the dashboard do not work. If one or more light sources fail, then most likely this is due to burnt-out lamps. The problem is solved by replacing devices.
2. The backlight has stopped functioning altogether, while all instruments and indicators light up. Apparently, the reason must be sought in the inoperability of the brightness control itself; it could have broken down. With constant use of this regulator, its connection contact with the on-board network may have come loose, so you need to check the wiring. The reason may also be a blown fuse located in the mounting block.
3. The backlight does not turn on, and none of the indicators or sensors work. Perhaps the panel itself was “covered” or the block with the wires connected to the panel was damaged. You need to remove the device and carefully check all circuits.
4. The speedometer does not work - the needle does not rise or rises, but very slowly and jerkily. With such a problem, the cause should be sought in the speed sensor, which can be electronic or mechanical. If it is mechanical, then check the condition of the tips that go into the speedometer itself and the gearbox. The end of the cable connected to the speedometer often wears out; you can try to solve the problem by wrapping a piece of food foil around this end. If the sensor is electronic, then you need to check the quality of the contacts.
5. Indicators, for example, turn signals or optics, do not turn on. It is necessary to check the functionality of the steering column switches for low and high beam headlights, as well as turns.
6. The fuel volume sensor does not function, the needle does not move or has risen all the way and does not fall. In the first case, the reason may lie in the failure of the controller itself, located in the fuel tank. You need to find the sensor and check its functionality. In the second case, the possible cause is a short circuit in the electrical circuit; you will need to test the wiring with a tester.
7. The tachometer does not work. Again, the reason must be sought in the crankshaft position sensor - it could have failed, or the contact could have come loose from it. Most often, the reason for the malfunction of the sensors on the device is associated with oxidation of the contacts; they should be checked first.

Removing the torpedo on the old model 2112

To completely remove the device from the car you will need:

1. Turn off the on-board power supply.
2. Remove the screws around the panel.

• Move the plastic cover of the shield aside and disconnect the wires from the buttons.
• Unscrew the panel fasteners.
• Then the device moves away from its seat and is disconnected from the on-board network.

Additional panel

The additional front panel of the new-style BSK control has indicators:

• An oil can is shown. If the light works, check the oil level;
• An icon lights up, which, with some imagination, can be “identified” as working wipers. This indicates that there is not enough windshield washer fluid in the tank;
• Conventional image of a thermometer over a container with liquid - high temperature of antifreeze;
• A crossed out light, which the arrow points to, is a sign that the brake light or parking lights are not working;
• If the light with the image of a wheel with brake pads lights up, it is quite possible that the pads are worn out and require replacement;
• The sign of a man with a seat belt indicates that the seat belt should be fastened.

Speedometer

The leading role in driving control is assigned to the speedometer, which controls speed. Removing the speedometer will reset all data on the board.

The VAZ 2110 car has a speedometer that has two types of counters (odometers):

• The first shows the total distance traveled;
• The second shows the distance traveled during the day.

To analyze fuel consumption, the distance traveled per day, and calculate the average, as well as determine whether the car needs repairs, you can completely reset the results of the second counter. The driver can reset the speedometer daily and compare the results of how the components work.

To reset the values ​​on the board, use the corresponding button. You can reset the counter only after a complete stop, when the machine components are working. This cannot be done. If the button does not reset the numbers, it needs to be replaced.

Fuel level indicator

The device indicating the fuel filling level of the tank operates in combination with a control sensor; it is installed in the fuel tank. If the lamp shows a resistance of 284-334 ohms on the board, then the indicator needle will be located near the beginning of the scale.

If the sensor reports a resistance identical to the level of 102-136 ohms, then the needle will move to the middle of the scale. If the sensor value is 8-26 ohms, the needle will move to the very end of the scale. If the resistance and the needle level on the scale do not match, then repair of the machine is inevitable.

Coolant temperature indicator

The device operates in combination with a coolant temperature sensor, which is installed in the cylindrical heads. When the temperature indicator shows a resistance of approximately 650-1340 ohms on the board, the arrow should be located at the initial marks of the scale.

If the resistance results on the dashboard have reached 76-88 OM, then the arrow should reach the section of the scale marked in red. The arrow reaches the end of the red scale when the sensor resistance is 41-51 ohms.

If the resistance data and the arrow level do not match, then the machine requires repair or replacement of parts.
