Emergency warning button VAZ 2114: review and replacement options

Complete electrical diagram of the VAZ 2114 with decoding

The complete package of electrical equipment of the VAZ 2114 can be divided into two types. The fundamental differences are due to changes in equipment depending on the year of manufacture and equipment of the car. In this case, the entire drawing can be divided into several zones.

  • The engine compartment is responsible for providing voltage to sensors and instruments located directly inside the engine compartment.
  • Salon compartment. The part is primarily used to connect the front and rear compartments.
  • Instrument panel assembly. The pinout is displayed directly on the controls and dashboard. All elements of the on-board network are combined here and connected to buttons or indicators.
  • Stern joint. The small module combines chain elements located at the rear of the machine. Typically, the segment is subject to frequent damage, which is due to the constant transportation of goods in the luggage compartment. When moving over obstacles, loads can damage sensitive equipment.

You can also separate small units – these are door units, windshield wipers and others. For ease of perception, each beam is considered separately.

VAZ 2114 instrument panel pinout

The terminals of all vehicle equipment are concentrated here. Due to the fact that the unit is located under the dashboard and is subject to constant condensation or fogging, some users treat it with hot melt adhesive. Even a thin coating can reliably protect the device from water ingress.

Elements are connected to devices or controls:

  • 1 – switch key for heated rear glass;
  • 2/6 – fog light switches, for rear/front module;
  • 3 – plastic block for activating head optics and turn signals;
  • 4 – fuse block;
  • 5 – wiper mode switch;
  • 7 – on-board system indication;
  • 8 – supply voltage to the additional harness;
  • 9 – dashboard;
  • 10 – “male” for powering the on-board computer;
  • 11 – terminal to the ignition device;
  • 12 – for door wiring;
  • 13/14 – fuses;
  • 16 – ignition break;
  • 17 – stove motor;
  • 18 – secondary resistance of the stove;
  • 19 – current supply to the ignition unloading relay;
  • 20 – protective relay for rear fog lights;
  • 21 – starter fuse relay;
  • 22 – remote socket for a portable lamp;
  • 23 – power supply for the cigarette lighter;
  • 24 – for illumination of the glove compartment;
  • 25-27 – illuminators;
  • 28 – stove switch;
  • 29 – tidy lighting with rheostat;
  • 30 – stop switch;
  • 31/32 – horn/hazard warning switch, respectively;
  • 33 – backlight of the stove panel;
  • 34 – fuse;
  • 35 – protective relay for seat heating elements;
  • Ш1/4 – mounting block jumpers;
  • X1/2 – dashboard controls;
  • A – protective ground output (usually black).

Installation of an electric window regulator (ESP) on a VAZ-2114

The most popular window lift systems on the VAZ-2114 are rack and pinion types. Their connection is carried out according to the scheme described below.

  1. Disconnect the on-board power supply from the supply. To do this, remove the terminals from the battery, you can close one - the negative one.
  2. All the wires that come with the ESP on the VAZ-2114 are twisted together into a bundle.
  3. The mounting block is removed by unscrewing the screw that controls the position of the latch.
  4. A wiring harness is mounted into the block in place of the connector of the block.
  5. The door trim is removed.
  6. The ESP is installed, along with all the buttons and keys.

By the way, you can make a choice if you wish. Install the buttons and keys that control the window regulator either on the door panel or on the control unit. In the latter case, you will need an additional wire and knowledge of the theory of pinout of the ESP button.

Electrical equipment of the front of the car

The following is a breakdown of the front cable bundle, excluding fog lights:

  • 1 – output terminals of the starter contact group;
  • 2 – battery, connection of power cables;
  • 3 – standard “father” of the generator;
  • 4 – blocks for connecting the power conductors of the battery and generator to the front assembly of electrical equipment;
  • 5 – part of the fuse mounting block;
  • 6 – standard horn;
  • 7 – sensor that measures the temperature of antifreeze in the power plant;
  • 8 – standard sensor for measuring the washer fluid residue in the tank; when activated, the corresponding indicator on the device lights up;
  • 9/10 – left and right headlights, respectively;

  • 18 – similar for the engine cooling system;
  • Ш5-8 – mounting block connectors;
  • A1/2, B1/2 – grounding terminals.

Reworking the low beam button

As already mentioned, the button for turning on the low beam and the button for the dimensions of the VAZ 2114 are combined and located in pairs. Their main drawback, which most car enthusiasts point out, is the absence of a power-on LED on the low-beam headlight button.

This problem is quite serious, since very often it becomes unclear whether the headlights are working or not (especially during daylight hours). You can solve this by upgrading the button yourself.

For this you will need:

  • a button that will be redesigned;
  • the second button is the same - donor;
  • soldering iron or (better) soldering station.

The button modification should be carried out according to the diagram shown here. Resoldering the LED itself from one board to another is highly not recommended, since this requires a soldering station equipped with a hair dryer, a special flux and high skill in working with them.

First, we need to remove the main button from the car panel (how to do this has already been discussed above).

After it is removed and disconnected from the wires, perform the following operations:

  • remove the keys by prying them off with a flat screwdriver;
  • we disassemble the body of the buttons by pressing the latches with a screwdriver (the buttons themselves at this moment must be in the “on” position);
  • we see that the sidebar button has two diodes (backlight and indication), and the low headlight button has only a backlight button;
  • remove a pair of legs and a pair of contacts from the donor button;
  • we rearrange them into the free spaces on the working button;
  • remove the board from the donor button with two diodes and insert it into the working button instead of the board with one diode;
  • solder the board to the legs that were added;
  • make a hole in the button cover (this can be done with a sharp knife or simply punched with a flat screwdriver).

The junction of the newly installed legs and the new board must be well soldered. Otherwise, the button may quickly fail or not work correctly.

After all these operations have been completed, all that remains is to assemble everything in the reverse order and install the upgraded button in its place (during installation, it is important that all the mini-latches on the case fall into place).

We study the designation of icons on the instrument panel of the VAZ 2114

The VAZ 2114 dashboard is the main information block, which displays data on the current functional state of the car. It is located on the dashboard, directly in front of the driver's seat.


Tidying VAZ 2114, 2113,2115

The panel itself contains three types of elements:

  • Indicator lights indicating the amount of consumables required for the operation of the car - gasoline, oil, brake fluid, etc.;
  • Speedometer and tachometer;
  • A control element for switching the speedometer operating mode.

Also, the concept of “instrument cluster” usually includes levers for turning on turn signals, buttons for controlling headlights, heater, and other communications of the car.

Euro emergency warning button VAZ 2115

I finally decided to make my own emergency signal button (or, more simply, an “emergency light”). In our Russian VAZs 2113-2115 is located in a very inconvenient place. To be more precise, behind the steering wheel. And in the modern rhythm of life, when it has become customary to “blink” the emergency lights as a sign of greeting or gratitude, such an arrangement is unacceptable.

I started by ordering “relay HLS-4453(18F)-4, DC12V, 4 groups of contacts. 5A" from the site www.ekits.ru/index.php?product >

Then I bought 1.5 wires, many wrote that they needed exactly these, but they were too big, 0.75 above the roof would be enough. I bought, as the common people say, “PAP” and electrical tape. Next, a soldering iron in your hands and a diagram in front of your eyes.

Everything is quite simple, but you waste a lot of time, if you assemble it for the first time, it took 3 hours to assemble it from scratch)) Then INSTALLATION: I forgot to take most of the photos, so I took them from other users: www.drive2.ru/l/363984/ and www.drive2 .ru/l/1042092/

We disassemble the instrument panel and remove the casing.

We remove the casing and disassemble the old emergency button and move the wires to a place convenient for us.

We begin to slowly collect our miracle. We put the button in a place where it will be more convenient for us to use it.

We assemble the wires from the new button to the old one according to the diagram.

Just in case, I tied it with electrical tape so that it wouldn’t fly out of the connectors on bumps. Next, install the Din rail in the free space. And tighten the nut and bolt to 5.

We install the block with the relay on it.

And finally, we begin to connect to the dimensions and the dashboard itself.

I draw your attention to the fact that according to the diagram there are two minuses, they can be combined into one, but I made them in 2 different ones and connect them to the dimensions block, there are 2 black wires, both minuses, I did both)) And the dimensions of the new one I connected the buttons to the white wire on the block.

Next we move to the dashboard itself. We unscrew it, it is attached to two self-tapping screws. At the back we see two blocks, white and red, we need the red one and connect the wire there that goes according to the diagram into an empty socket.

This is so that the red triangle glows (you can do without it). Looks really cool. PS Some panels do not have a triangle light bulb, you have to buy one and screw it in.

In the end, this is how my button looks

Spent about 2 hours on installation.

Everything you need for the euro button:

1. Relay HLS-4453(18F)-4, DC12V, 4 groups of contacts. 5A — 106 rub. 2. Block for relay HLS-4453(18F) - 62 rub. 3. Euro button - 91 rub. 4. Block for the euro button - 50 rubles. 5. Din rail - 7 rubles. 6. Dads - 7 pcs. — 40 rub. (we buy 6 large and 1 small). 7. Wires 1.5 - 7 meters * 8.2 rub. = 58 rub. (I repeat, it’s better to take 0.75 wires and 7 meters was not enough for me, take 8 meters). 8. Electrical tape - 15 rubles.

To be honest, the standard emergency lights are boring; it’s inconvenient to reach over the steering wheel when you need to thank someone. I ordered a “Relay for installing the Euro emergency stop button VAZ 2108-2115” from VAV-21123. A week later the package arrived. I installed it without much difficulty, disassembled the panel, and connected it according to the diagram. I dragged the standard corrugation with emergency signal wires from the steering casing to the on-board computer, and the new emergency signal relay was also located there. The hazard warning light icon on the dash was connected to contact D on the button (oddly enough, the light bulb was already in the dash). I placed the button behind the heated glass, and moved the heated glass downwards, then next to the heated glass I will put a button for heated mirrors (once I buy these mirrors). Thanking drivers has become much more convenient. Price: The emergency kit itself is 665 rubles. including delivery Terminal for connecting the delta on the dashboard - 2p. Plug for a hole in the steering wheel casing - 10 rubles. PS: If you liked it, click like

Pinout of on-board computer VAZ 2114

In standard drawings of electrical equipment, the BC block section is missing due to its uselessness. Initially, it is assumed that the motorist will not independently repair or maintain the complex control unit. But some users still take risks and install the system themselves. In older versions of cars, such a module is missing or insufficient for comfortable operation of the car in its modern form.

To connect wires to the module, you will need to buy a standard 9-pin header and connect the following wires to it:

  • 1 – green wire comes from the fuel consumption sensor;
  • 2 – the ignition cylinder is powered through an orange cable;
  • 3 – power core from the battery, usually a red wire with a white stripe is supplied;
  • 4 – grounding or ground, standard color – black;
  • 5 – 6k line, usually a gray wire;
  • 6 – Mute – green shell with a red line;
  • 7 – the backlight in the standard pinout is output from the marker optics key;
  • 8 – a sensor that displays the remaining fuel in the car’s gas tank can be connected directly.

How to prevent electrical equipment breakdowns?

In order for the VAZ 2114 pinout to be required as rarely as possible, the user is required to follow a number of simple rules and recommendations.

  • Periodically treat all metal parts with special oil. In this case, it is first necessary to clean the copper patches from oxides and traces of corrosion. Such lesions provoke a deterioration in the transmission of signals, which can be perceived by the car as a breakdown.
  • Every 20-30 thousand kilometers, check all equipment and plastic plugs for looseness or reduced fastening rigidity. With constant vibrations typical of vehicles, plastic clamps can fail and cause breakdown.
  • Monitor the correct battery charge and the serviceability of the generator. Some machine devices do not work correctly when there is a strong voltage drop.
  • Every 40,000 km, check the condition of the wires themselves. With constant use, the braids of the power cores may crack or dry out, which increases the likelihood of a short circuit in the on-board lines. This may also cause a fire.

Button for dimensions and low beams of VAZ 2114: features and replacement

For greater convenience, the button for turning on the low headlights and the button for turning on the dimensions of the VAZ 2114 are made in pairs and are located on the European panel of the car.
Both of them are equipped with additional built-in LEDs (two for backlighting, as well as an indication diode for side lights). As a rule, there are no problems with the operation of these buttons, but if necessary (for example, if they break), you should know how to replace them.

Everything is done in the following order:

  1. Remove the plug under the button panel (it can be removed simply by hand, without tools).
  2. Push the buttons into the interior by pressing them from the inside.
  3. Gently pull the button, rocking it slightly, and remove it from the block.
  4. Install a new button into the block.
  5. Place the buttons back into the panel.

As you can see, the replacement can be done almost instantly, without applying any great effort or using a special tool.

Another important point that should be highlighted is the pinout of the VAZ 2114 size button. It may be needed, for example, when replacing an old type button with a button for a Europanel.

You can see it most clearly in the following diagrams: for old type buttons

for new type buttons All letters indicated in the diagram correspond to the output contacts of the buttons and have similar markings to them, and the colors of the wires are indicated by letter abbreviations.

Also, the pinout of the VAZ 2114 light switch button can help when troubleshooting problems in the operation of the buttons themselves, for example, if the backlight of one of them does not work.

In this case, it should be taken into account that the contacts:

  • 6-V or 5-V - responsible for the operation of the low beam indicator;
  • А-В — illumination of the low-beam headlight button;
  • С-D — indicator for turning on dimensions;
  • E-D — illumination of the button for turning on the dimensions.
