Relay for rear fog lights VAZ 2114 diagram

Schematic electrical diagrams, connecting devices and pinouts of connectors

Detailed color diagrams of the VAZ 2114 wiring (carburetor, injector) are provided with a description of the electrical equipment for various modifications. The information is intended for self-repair of cars. Many electrical circuits are divided into several sections for ease of viewing via a computer or smartphone; there are also circuits in the form of one picture with a description of the elements - for printing on a printer.

The VAZ 2114 (Samara-2) car is built on the VAZ 21093 platform and is an improved version of it. The first prototype of the hatchback was assembled back in 2000. A year later, the Volzhsky Automobile Plant produced the first pilot batch of 50 VAZ-2114 cars, and in the same 2001 the hatchback was first introduced to the market. The interior features a new instrument panel, a new steering wheel, an adjustable steering column, power windows and a new heater. Years of production 2114: 2001—2013

The fourteenth model was previously equipped with a 1.5 liter eight-valve engine, borrowed from the VAZ 2111 model with an injector. A little later it was replaced by the VAZ 11183-1000 version, which complies with the Euro-3 standard. The VAZ 2114 injector received a more powerful engine, and this is one of the reasons that the wiring of the 2114 has also changed.

A wiring harness has been added for connecting to the electronic switch. A harness has also appeared for connecting to the ignition module terminal.

Replacing high-voltage wires will require additional attention, because the connection procedure depends on the year of manufacture of the car. Until 2004, 4-pin ignition modules were installed, and after that - 3-pin. Connecting the adsorber valve to the injection system controller also provided another additional element. An adsorber is an electromechanical device used for ventilation and removal of condensate in a gas tank. Complications also affected the interior part. The dashboard received improvements in the form of the appearance of a BC (on-board computer), a new instrument panel and a change in the position of the glove compartment.

Wiring diagram VAZ-2114 new models

The updated engine has a new injection scheme, so it was necessary to use some new devices, as well as replace the ignition coil with a more efficient one and adapted to Euro 3 conditions. In order to comply with them, the engine had to minimize the amount of CO at start-up. And for this it was necessary to lean the mixture. Since a lean mixture ignites worse, it needed a more powerful spark to spark. This explains the use of a coil of increased power.

How to check the fuse?

Next you need to find the faulty one. There are two ways (depending on the type of fuse).

We either simply take it out and see if the middle part is intact (in the photo - burnt out on the left, serviceable on the right).

The second method is more accurate. The fact is that the human eye may not notice a burnt jumper.

We do the following: Turn on the non-working circuit (for example, dimensions), without removing the fuse, look at the voltage at one end of the fuse, then at the other. If there is voltage at one end, but not at the other end, then the fuse has blown.

PTF service

At the same time, many owners of the first ten cars do not know where the fog lamp fuse is located. And if it malfunctions, they don’t know how to replace it.

To get to the PTF fuse, you need to remove the mounting block from the instrument panel niche with your own hands

On models after 2000. fuses are grouped in a single block.

Their technical parameters are as follows:

The rear PTF fuse is marked F20 and is designed for a current of 7.5A;
Fuse F4 at 10A is responsible for protecting the front right fog lamp;
Fuse F 14 at 10A is responsible for protecting the front left fog lamp.

Side of VAZ fuses of the tenth family

The algorithm for the operation of fog lights has also been changed.

The headlights are turned on by pressing a button that supplies power to a relay type 113.3747 installed in the mounting block;
Turning on the PTF on VAZ 2110 cars is only possible if the headlight switch is set to the exterior lighting position.

In other words, PTFs are activated only with side lights or low beam headlights. At the same time, the activation is indicated to the driver using a light indicator on the button and on the instrument panel.

There are no particular problems with replacing lamps in the headlights, since they were installed in an open position for service. But with the rear lamps we had to struggle a little, since the entire structure of the headlight unit was located in the trunk lid.

To replace a burnt-out lamp, you must remove the entire unit

Content

Principle of operation

The relay is designed to turn on and off the rear fog lights of the vehicle in accordance with the algorithm according to UNECE Regulation 048:

The rear fog lights are turned on by pressing the locking button once without locking, connected between contacts 3 (“Common”) and 5 (“On/Off”) when there is supply voltage on contacts 2 (“Fog lights”) and/or 6 (“ Low beam/high beam") of connector X1 (i.e. if the low or high beam headlights and/or fog lights are on).
The rear fog lights are turned off by pressing the same button once or when the supply voltage is removed from contacts 2 and 6, and if the voltage is reapplied to contacts 2 and/or 6, the rear fog lights do not turn on.

Replacement is easy

Having figured out where the block that controls the operation of the PTF power circuit is located, replacing it is a trifle. It is much more difficult to correctly diagnose a breakdown. Therefore, if for some reason there is no power to the rear fog lights, you should start by checking the fuse and cleaning the contacts.

For the latter, you can use regular fine-grit sandpaper. This must be done extremely carefully, because the relay block contains electromagnets, with the help of which the contacts are switched (when the light button is pressed).

If there is no power supply to the VAZ rear lights, and the fog lights do not work together with it, then this does not indicate a breakdown of the relay, but a damage to the electrical circuit or a short circuit in the system (most often, the absence of a negative contact from ground).

To accurately determine the cause, it is advisable to use a multimeter. If only the rear lights do not light up, this indicates:

damaged fuse;
absence of 1, 2, 6 contacts (voltage on them);
switch closure (momentary button);
problem with electrical wiring (break).

As practice shows, the relay on the PTF VAZ 2114 fails extremely rarely. Most often, only a break in the contacting area or mass contact occurs due to body vibrations. A faulty relay should be the last thing to blame.

What are fog lamps for?

The main task of the PTF is to illuminate the space in front of the car. Correctly adjusted “fog lights” can illuminate a section of road 10–15 meters long. This distance is quite enough for safe movement by car in poor visibility conditions. The switching on and off of such lighting devices must be fully controlled by the driver.

Adjustment of fog lights is carried out during their installation. The procedure does not take much time, but requires care and precision. You can install the rear and front PTFs yourself.

Fog lamp relay VAZ 2110: differences in factory configuration

Like any modern car, the VAZ “ten” was constantly improved during the process of mass production. However, all modifications concerned the originally installed components and assemblies of the vehicle. For example, front fog lights were not included in the external lighting of the car, but both a relay and a PTF control button were installed in the electrical circuit.

The VAZ 2110 rear fog lamp relay has been installed since 2000

For reference: in the rear block headlights, the side light lamp had a second filament, which served as fog lights. It was activated by a button on the front panel and made it possible to improve the visibility of the car in conditions of poor visibility for other road users driving behind.

How can you install PTF on a VAZ 2113, 2114, 2115

Installation of fog lights on a car can be done in different ways. The car owner chooses a specific option based on his own capabilities, preferences and wishes. There are three main ways to install PTF:

The disadvantage of this method is that the cost of the work is too high.

One way to install foglights is to buy a bumper with already built-in PTFs

Purchase and subsequent installation of a set of “fog lights” from the PTF kit

Installation diagram of fog lights

The connection of fog lights is carried out according to certain rules. They, first of all, relate to the placement of PTF on the car. The locations for installing headlights are strictly defined.

Layout of daytime running lights

Manufacturers of modern car models pre-mark the PTF installation locations on the bumpers. As a rule, such lighting elements are most often available in the luxury version of the car. If the headlights themselves are missing, then their installation sites are closed with special plugs.

Distance at which fog lights can be placed

How to install a PTF: necessary materials and tools

Installation of fog lights, regardless of the chosen installation method, requires the presence of certain parts and tools, without which it is impossible.

What are the button and relay for?

A special button and relay are a must - “fog lights” are very powerful equipment for car electrical wiring. The absence of such parts can provoke high current loads on the terminals and the ignition switch, which will cause burnout of contacts, damage and overheating of the insulation protection and short circuit with failure of the electrical network.

In order to install fog lights on a VAZ, you need to assemble certain parts in advance or purchase a ready-made kit. The cost of such a set rarely exceeds one thousand rubles.

The PTF kit includes:

wires with blocks and terminals for a specific VAZ model. There are three of them as standard: one connects the headlights, the second goes to the relay from the switch, and the third goes from the relay to the fuse box;

Which PTFs should you prefer? The headlights themselves are chosen by the driver to his taste, but the main thing when choosing is not to make a mistake with the power, so as not to overload the generator and the car’s electrical wiring. It is better not to purchase headlights with xenon: the generator has a certain power reserve, but is not designed for too high loads. Regular light bulbs will be sufficient.

Signs of problems with the PTF relay

The main reason why it may be necessary to replace the fog lamp relay is the malfunction of the latter. But don’t rush to conclusions and rush to buy a new relay. By itself, it is a fairly reliable design, and in combination with a small number of consumers and low current in the circuit, this device rarely fails.

Therefore, before replacing the PTF relay, you should check other elements in the fog lamp circuit, namely:

light bulbs;
wiring;
power button;
circuit breakers.

The latter should be given special attention, since two fuses are responsible for protecting the fog lights, designated in the general block as F8 and F9. In some cases, they may be serviceable, but due to oxidation of the contacts they will not pass electric current. In this situation, they should be carefully removed and their contact surfaces, as well as the contact surfaces of the sockets in the common block, should be cleaned. Very often, after this procedure, the headlights begin to work.

A sure sign that the fog light relay is working properly, and the cause of the problem should be sought in the wiring or fuses, is a situation when only one of the headlights does not light up. Checking and, especially, replacing the relay in this case is pointless.

If, after checking, all the links in the fog light chain are in good condition, but the headlights themselves still refuse to turn on, you should proceed to checking and, probably, replacing their relays.

How to connect fog lights with your own hands

Before directly installing the headlights, their location is determined. In the case of the VAZ 2115 car, the bumper already has standard holes for installing additional lighting fixtures. Similar ones can be cut in the bumpers of VAZ 2113 and VAZ 2114.

There is no need to spoil the appearance of the bumper - fog lights are easily installed on special brackets. Many PTF kits contain special decorative plugs that add attractiveness and neatness to the installed headlights and facilitate the installation process.

Installation and connection algorithm

Installation of a power button in the car interior. In the case of the VAZ-2114, the place for the button is on the left side of the driver on the front panel. However, its placement can be arbitrary - the main thing is that it is convenient for the driver to drive the car. Often, PTF power buttons are installed instead of plugs on the control panel.

A PTF activation button is installed in the cabin in a place convenient for the driver.

The functionality of the entire connection can be checked by turning on the side lights - only then will the fog lights work.

Fog lights only function when the side lights are on

After completing the installation of the PTFs on the car, they only need to be adjusted correctly. The flow of light should not blind drivers in the oncoming lane.

Old style mounting block

Older car models have a different type of mounting block. The fuse for VAZ 2114 fog lights is also installed separately for each headlight. In the old-style block, the element responsible for the right fog is designated F 9 , and for the left one - F 8 .

The maximum permissible load for each element is 7.5 amperes.
F9 and F8 are located first and second from left to right in the bottom row.
