Like in any car, instrument panel VAZ 2107 combines instruments and indicators that display performance indicators of the engine and other critical components and assemblies. This allows you to notice malfunctions in time and prevent premature breakdown of machine components. To do this, you need to know what each device and warning light on the instrument panel is responsible for, and monitor their readings.
Tidy VAZ 2107: icon designations
If everything is clear with the main elements and arrow indicators, the indicators need to be deciphered.
The bulk of the light bulbs are located strictly in the center of the panel. There are 7 control indicators in the column; their explanation is presented in detail in the pictures below.
- The first thing to install from the top is turning on the turn signals. The indicator is activated when pressed or alarmed.
- Next is the check engine fault indicator. The light bulb is used only on injection engines.
- The third one from the top is a faulty battery. If the indicator lights up, this indicates a breakdown in the generator line (the battery is not charging).
- In the middle of the column there is a light bulb for turning on the dimensions. This indicator indicates normal operation of the device.
- An indicator for activating the main beam of the head optics is installed even lower. The blue indicator indicates that the exterior lights are operational and working properly.
- The penultimate light is an indicator of the critical oil pressure in the engine crankcase. If it lights up constantly, you need to add fluid to the required level or check the functioning of the pump.
- The last place the manufacturer placed the parking brake activation indicator. Usually the light comes on when the lever is raised.
Also on the dashboard you can see a yellow diode indicating a critically low fuel level in the tank.
The light comes on only when the container is empty and there is no more than 5 liters of gasoline remaining.
The instrument cluster is not equipped with an emergency warning symbol; it is located on the power button.
Identification of buttons
Several switch keys can be installed on the car’s dashboard, which are responsible for activating certain elements and parts of the car. The following is a description of the main buttons on the car dashboard.
| Number | Purpose |
| 2 | Turn on the sound signal. |
| 6 | Headlight position regulator. |
| 10 | Emergency button. |
| 13 | Heater switches. |

Removing the instrument panel
You have to remove the dashboard of the “seven” to replace lamps, instruments or in order to do tuning of the VAZ 2107 dashboard. Removing the “tidy” of the VAZ 107 does not require special tools and extensive experience in plumbing. The work order is as follows:
- disconnect the ground wire from the battery;
- use a screwdriver to pry off the heater control levers;
- unscrew the nut securing the daily mileage reset handle and push the latter behind the instrument panel;
- remove the plug of the self-tapping screw securing the dashboard;
- unscrew the screw and pull out the instrument panel;
- Unscrew the speedometer cable fastening nut by hand and uncouple it;
- disconnect the vacuum supply hose from the econometer;
- remove the wire blocks;
- remove the “tidy” from the car.
Now you can repair, change or tune the dashboard.
To install the panel, perform the steps in reverse order.
The VAZ 2107 dashboard does not light up: reasons
If the device on the seven stops activating, check the components.
- Corresponding fuse. The insert often burns out due to moisture or power surges in the on-board network.
- Next, the wiring is checked. Some pins may not fit well or touch adjacent terminals, causing shorts and shorts.
Tidy 2107 does not work
If, when you turn on the ignition when the car is cold, the car does not start and the shield does not respond, check the above points and additionally inspect the ignition switch cylinder. Usually in this place the contact burns out or the connections oxidize, which causes loss of ignition.
Highlight the mass damage. Wires may oxidize, resulting in loss of contact.
2107: the tidy does not light up, the starter turns
When the shield goes out or the light is dim, check the operation of the external lamps and the illumination of the car interior. When everything is in order, remove the device and check the contact groups of the module.
VAZ 2107: temperature sensor on the dashboard does not work
The element fails only in two cases.
- The sensor has failed.
- Module wiring is damaged.

Ways to change speedometer readings
Despite the fact that the years that were accompanied by a total shortage have passed, nowadays it is now possible to purchase any auto part without difficulty, the habit of “embellishing” the condition of the vehicle has remained with car owners.
Car manufacturers have abandoned mechanical speedometers, equipping modern cars with electronic devices in order to somehow try to eradicate this addiction to deception, but it is completely impossible to stop it. Many people still strive to increase the speedometer mileage.
How to change the mechanical speedometer readings
Mechanical speedometers often accompanied technical means until the turn of the 20th and 21st centuries. Although some domestic cars continued to be equipped with them even before 2007.
Due to the fact that mechanical speedometers are simple devices, even an inexperienced car enthusiast can twist the speedometer himself, who will first familiarize himself with the advice of experienced craftsmen.
Initially, the speedometer is removed and connected to a motor, after starting which the mileage will automatically increase or decrease. By the way, some car owners, indeed, not only reduce the mileage, but also increase it, on the contrary, thereby convincing the buyer that a vehicle with a certain mileage has already successfully passed maintenance and therefore does not need repairs.
When removing the speedometer, it is impossible not to break the seal, so this trick may not work for all purchasers. Although some brands of cars are accompanied by fastening the speedometer in such a way that does not require its complete removal, it is enough to disconnect only the drive cable.
When trying to twist the speedometer, it is not recommended to rush, since the numbers will not be located on the same line when the motor is running quickly, giving away tricks of manipulation to the buyer.
How to change electromechanical and electronic speedometer readings
Electromechanical speedometers replaced mechanical ones in the eighties, but lasted until about 2008. The drive cables in them were replaced with electrical wires.
Manufacturers installed special indicators in the gearbox that read pulses from the rotating modulator.
It is possible to twist an electromechanical speedometer using a special pulse generator, although some craftsmen manage to perform such work using an electric motor on which the modulator is directly installed.
Modern cars are already equipped with electronic speedometers, since manufacturers are interested in a serious degree of protection. Owners of modern technical equipment who want to know how to twist an electronic speedometer can get advice on this issue from experienced craftsmen, but one cannot hope for an easy solution to the problem.
In most cases, you cannot reduce or increase mileage yourself, so you have to turn to specialists
Unfortunately, this type of service is accompanied by a considerable cost, so it is important to weigh the feasibility of such actions
And yet, if someone really wants to know how to twist an electronic speedometer, the craftsmen can reveal the secret that all actions are accompanied by the use of computer equipment, in particular, a special programmer that connects directly to a microcircuit containing information about the car’s mileage.
Having ensured such a connection, the programmer manually enters the necessary parameters, changing the mileage of the car. You can check the mileage by connecting the computer to the diagnostic socket. The advantage of this method is that there is no need to remove the instrument panel. However, the disadvantage indicates that it is extremely difficult to have the appropriate software that allows such manipulations, since it is only available from the manufacturer or official dealer, who value the prestige of the company and are unlikely to want to distribute the software to everyone.
So, adjusting the speedometer indicator is a real relic of the past, which has confidently and firmly penetrated modern life and is not going to lose ground, allowing owners to “cunningly” but profitably sell their cars.
How many kilometers does it twist?
You yourself understand perfectly well that it would be stupid to reduce the value to 300-400 thousand on a car with almost a million kilometers traveled. This will become obvious even from the condition of the car itself and a number of indirect signs. Therefore, twisting occurs carefully, within certain limits, beyond which it is potentially very risky. Statistics show that in most cases the twist is a quarter of the current value. This does not make it possible to detect fraud by indirect evidence, but at the same time the car automatically becomes more expensive with such mileage indicators.
Let's assume that you are shown a car with the number 250 thousand kilometers on its display. There is a high probability of actual mileage of 300-350 thousand. But there are also scammers who have no sense of proportion. They significantly reduce the actual values, at significant risk. At the same time, there are active buyers who believe what they see, and find out about the actual mileage at the next technical inspection.
The actual values depend on how conscientious the seller is. Let’s not hide the fact that there are many people who don’t even think about twisting before selling. But there are also those who do this professionally and earn decent money from deception. You cannot completely rely on the seller’s clear conscience and assume whether the mileage is incorrect or not. You definitely need to figure out how to check the mileage of a car. But to do this, you need to understand how such manipulations with the odometer are generally carried out.
Check actual mileage based on vehicle age
Checking and adjusting thermal clearances in the Renault Logan valve drive
Let's start with statistics. The actual mileage of a passenger car, which is used exclusively for family and business trips, usually does not exceed 20 thousand kilometers per year. Let's take the average age of the used market to be 5 years. It turns out about 100 thousand mileage.
But, you need to take into account that the car could perform transport services. And there is a completely different mileage. In a couple of years, such “chariots” cover up to half a million kilometers, if the engine and everything else hold up.
Therefore, it is very important to distinguish a personal car from the car on which the taxi driver or courier worked. First, take a look at the interior, namely the front passenger and rear row (if equipped)
If only the driver's side is dented, and the rest are like new, this is clearly not a personal car. Secondly, look at the doors. Does the driver's side play, creaks, and doesn't close well? Read above. Thirdly, carefully look at the condition of the map, window control buttons, the condition of the steering wheel and pedals, and the scenes. Is it wobbly, creaky and scratched? Say goodbye to the seller. The final touch is a suspiciously polished body. This is an attempt to hide frequent scratches and advertising stickers.
It should be noted that you can rejuvenate the car directly in the passport, so carefully study the glass markings. Compare the data on the glass with the Internet and see in what year the batch left the assembly line. Just in case, check that the markings are identical on all car windows. If the markings are different, this may mean that the car is damaged.
In addition to glass, the car has a lot of parts with markings stamped on them indicating the year of manufacture. Such a stamp may well be on the windshield washer reservoir. Also, do not forget about the engine number.
Operating principle
The injection motor operates under the control of a complex electronic system. Only the interaction of all sensors allows such an engine to be operated without problems. The speed counting system also operates in this electronic circuit.
The electronic speed meter consists of the following components:
- EMF or speed sensor. It is an electromechanical part. This device works on the principle of creating electrical impulses from the interaction of a metal secondary shaft and an EMF magnet. When an additional gear tooth passes, the sensor closes, creating an impulse.
Some models are equipped with an electromechanical sensor. It doesn't have a magnet. The formation of electrical impulses occurs due to the transmission rotation of the gear on the drive rod. Rotation creates impulses based on the Hall device principle. - A network of wires connecting the EMF to the on-board computer. It is through this network that electrical impulses are transmitted from the sensor to the on-board computer.
- The receiver is a drive that is the main mechanism of the speedometer itself. The device receives already calculated signals from the ECU. Due to these impulses, the arrow is deflected by a certain angle.
This system is quite reliable. The maximum service life is at least 100 thousand km.
Relay on fuse box
The fuse block relays and the VAZ 2107 relays are located in the same fuse block. Their purpose:
- Rear defroster relay.
- Relay for washer and headlight cleaner.
- Power supply for sound signal.
- Cooling system electric fan relay (up to 2000).
- High beam relay.
- Low beam relay.
Checking the serviceability of the relay can be done using a multimeter. To do this, it is necessary to test the armature winding. Its resistance usually ranges from 50 to 200 ohms. It is safer to test connect the winding to the vehicle's on-board voltage. To do this, the relay must be removed from the relay and fuse block. If one terminal of the winding is connected to the positive terminal of the battery, and the other to the negative terminal, you should hear a characteristic click of the activated relay. The main causes of relay malfunction:
- burning of contacts;
- break or burnout of the relay winding;
- sticking of contacts.
General tuning aspects
By tuning the dashboard of a VAZ 2107, you can change not only the appearance, but also improve its performance (video author - Auto overhaul).
