Rear PTF lights do not light up on VAZ 2110 Requirements for PTF installation

If you install fog lights on a VAZ 2110, you can kill two birds with one stone. Namely, to transform the appearance of the car, and increase the level of your own safety, and add comfort to driving at night.

Therefore, today we will talk about how to connect fog lights on a VAZ 2110, what is required for this and what result you will ultimately be able to achieve.

Logical conclusion

If you are not looking for simple ways, you can try to disassemble the relay itself and check what is wrong with it. Perhaps the movable plate has become sour or the contact has come loose. Since the part is small, you need to be very careful not to bend anything. Using a small soldering iron and some fine-grit sandpaper, you can bring the relay back to life and gain valuable repair experience in the process.

Replacing the VAZ-2110 turn relay is quite simple and quick. There is absolutely nothing complicated, so it makes sense to do such work yourself. It does not require you to have any knowledge of electrical engineering. The relay itself may “fail” if its time is approaching. When the first signs of a malfunction appear, such as intermittent relay failure, altered click frequency, etc., it is better to stock up on a spare part in advance. This way, if necessary, you can immediately replace the VAZ-2110 turn signal relay.

In order to maintain the temperature regime of the engines, a fan is used for cooling; it is usually equipped with an electric drive. The options to turn on and turn off such a fan are controlled automatically. On cars with carburetor engines, the TM 108 sensor is used for this; on cars that have an injection engine, control is carried out using a controller.

Fan control from temperature switching sensors largely depends on the temperature settings of the sensors, which are indicated on the case. As the temperature rises until the sensors are triggered, the fans do not turn on, which requires checking that the sensor is working properly. To check, you should simply close the contacts on the sensors; if this happens, then the sensor should be replaced with a new one. If the fan does not work after shorting the terminals, then it is worth checking the integrity of the supply wires according to the diagrams.

The cooling fans of the VAZ 2110 with injection engines can be turned on by an electronic controller. The response temperature is built into the controller program and can range from 100 to 105 degrees. A malfunction of the temperature sensor is automatically recorded in the fan error code when the engine is running.

There are also malfunctions that make it impossible for the controller to recognize malfunctions; in this case, the fan cannot turn on. To check circuits and sensors, it is worth removing the connectors from the temperature sensors at a time when the engine is at full speed. In the event that the malfunction of the circuits can be checked by the integrity of the fuses, it is also worth checking the serviceability of the wires and relays according to the exact circuits.

Many tens are set to reduce the effort during maneuvers and turns.

For an accurate and quick test, it is worth bridging the output to approximately 87 relays. If after this the fan works, then connect the relay without removing it from the block using a test lamp, the relay will work and the fan will turn on immediately. In this case, the faulty controller or drive will need to be repaired.

If you don’t hear a click after turning it on, then you just need to change the relay. When installing jumpers between pins 87 and 30, the fan does not turn on. If there is power at this pin, this indicates that there may be some kind of malfunction of the engine fans.

Hello everyone, guys. In general, the rear PTFs do not light up. What could be the problem?

Comments 22

Mine didn't burn either. It turned out that the old owner took out the light bulb. Apparently they were needed a lot. It happens

Very funny) Based on the fact that I turned to the people for help, you can understand that I checked everything on my own! There are light bulbs and they work!

Dadada, there's a block under the panel on the ZPTF

I've looked all over, no(

They turn on when the low/high beam is on, this is me, by the way, since several of my friends put up with non-working PTFs until I told about the low beam, thereby making a colossal discovery for them)))

Location

Since AvtoVAZ engineers tried to do everything so that car owners would not have problems replacing relays and fuses, it would be stupid to come up with a clever arrangement. Therefore, finding them is not difficult.

• The main unit is located to the left of the steering wheel;
• You will find the first additional block in the dashboard inside the niche, directly behind the main mounting block;
• The second additional block is located in the same place, only on the opposite side.

We will get acquainted with each block separately so that you do not have any confusion when searching for one or another fuse.

On injection engines with 16 and 8 valves, the location of the MB is identical, so the instructions are equally relevant for owners of both versions of the dozen.

Main MB

Relays and fuses are located here. Let's look at their descriptions in more detail and separately.

Let's start with the relay.

Designation	What is he responsible for?
Car lamp operation
Electric windshield wipers
Special relay that interrupts the turning lights when the hazard warning lights are activated
Turning on the low beam
Turning on the high beam
Area for installation of additional device
Rear window heating operation

Each fuse is indicated with a current rating and designation. This allows you to use a new fuse with parameters that meet the requirements of the equipment connected to it.

Designation	Rated current	What is he responsible for?
Lamps for license plate illumination, instrument panel illumination, indicator lights on the instrument panel, left side position lights, luggage compartment illumination
Low beam left headlight
Left high beam
Right front fog lamp
Electric door windows
Carrying lamp, cigarette lighter
Radiator fan, horn (horn)
Heated rear window
Windshield wipers and washer
Backup fuse
Right dimensions
Low beams in the right headlight
High beams in the right headlight
Left fog lamp
Heated seats in the cabin
Hazard signal, turn signals
Stop signal, ignition switch illumination, interior lighting
Interior heater, glove compartment light, cigarette lighter
Reversing light, brake light monitoring
Rear fog lights

First additional block

Inside the central panel there is the first of two additional blocks provided for the VAZ 2110. You can find it at the bottom left on the front passenger side.

This block provides three fuses. Each of them has the same power rating - 15A.

1. The first fuse is responsible for your vehicle's ignition and controller module.
2. The second protects the mass air flow sensor, heating sensor, speed sensor and purge valve.
3. The third is necessary to ensure protection of the injectors, as well as the fuel pump. So if problems arise with the fuel pump, the first thing we recommend is to check the condition of the fuse responsible for it.

Plus, the same block includes three relays:

• Relay number 4 is responsible for the electric fan;
• Relay number five is the electric fuel pump;
• The third relay is part of the ignition protection group on your VAZ 2110.

Second additional block

The second additional block should be looked for already in the driver’s feet, on the right. Behind the protective cover on the console you will find the required board.

There are three more components on it. They are responsible for:

• Immobilizer operation;
• Additional optics (mostly fog lights);
• For the operation of the car's central locking control.

Why VAZ-2112 headlights do not work and repairs

On VAZ-2112 model vehicles, left and right headlights are mounted on the front. This design combines both low and high beam. Manufacturers can be Bosch or Avtosvet, respectively, and the products have minor differences. However, the mounts are always located in the same places, which allows you to easily install headlights made in different factories. The light bulbs used are also absolutely identical. Their characteristic feature is the presence of only one filament coil.

What to do if for some reason the headlights installed on the VAZ-2112 do not work? We'll talk about this further.

Installation

A diagram for connecting fog lights on a VAZ 2110 is always offered with the purchased kit, so there shouldn’t be any special problems. But keep in mind that something may need to be corrected or adjusted to ensure effective operation.

Before installing fog lights on a VAZ 2110, you need to decide on their location. If the design of the car does not provide space for them, then they will be mounted under the front bumper.

The PTF connection diagram is as follows.

1. We install the wiring for fog lights on your car. This is done through the left side under the hood along the fender. The main wiring is approximately the same.
2. Now you need to connect power to the button, which is located on the dashboard. According to the factory diagram, power is installed from the fuse on the right dimensions. But you can use the light switch button or the lead from the ignition switch to turn on the head optics. That is, in such a situation, the fog lights will turn on when the ignition is on. Some take power from the output to the dimensions. This can be done, but is not recommended. If you forget to turn off the PTF, the battery will soon run out.
3. We connect the plugs to the headlights. If after this the fog lights on the VAZ 2110 do not light up, an error was made in the circuit. Check every element of the circuit. It is not difficult to determine where the fog lamp relay is located on a VAZ 2110, so make sure that the relay clicks. If it is present, then the coil will activate it. It is not uncommon to have to change a relay.

The last stage of installation begins after all the wires have been connected, the power has been turned on, and the light from the fog lights has spilled out. It's about adjustment.

Checking whether the PTF lights are shining correctly is quite simple. Get out on the road and see how the fog lights work. If the light is directed slightly downwards, the luminous flux touches both the road surface and the side of the road, then everything is working perfectly, and you don’t have to worry about the wrath of oncoming drivers whom you will blind.

If there are deviations from the norm, be sure to make adjustments. This work can be done independently, but ideal room conditions will be required. Therefore, it is better to trust the specialists from the car service center, who have a special stand, a flat area, and equipment for adjustment.

When the headlights on any car simply do not work, this is an ordinary case. The cause could be the light switch, fuses, or other common things. The “ten” has a feature, without knowing which you can check everything you can to the point of stupor, but still not find the fault.

Additional block

Additional relays are mounted on a bar and located under the dashboard, near the front passenger's feet. To get to them, you need to remove the right tunnel lining. Next to the additional relays is the electronic engine control unit (ECU).

If its connector interferes with access to the relay, disconnect it by first removing the negative terminal from the battery.

Question about glass color for fog lights

On old cars, the glass of fog lights was yellow , so many people think that it should be like this now, it is more correct and more efficient.

Article on the topic: Selecting and replacing brake fluid on a VAZ 2114

In reality, everything is different. Today, auto industry leaders use exclusively clear glass for fog lights, which are superior to yellow ones in many components.

The current fog lights on the VAZ 2110 are available in two versions - transparent and corrugated. Most people choose transparent glass, although in fact, corrugated glass is better. They provide a clear directional beam that can show its best side during fog or rain.

Materials and tools

You can easily buy a ready-made PTF kit with all the wires, and then you won’t have to figure out where the fog light relay is located on a VAZ 2110. However, if you purchase spare parts separately, this will diversify the installation options, plus it will allow you to save money.

Connection kit

Therefore, you need to purchase the following:

• Two sets of headlights;
• Plastic pads;
• Headlight frames;
• A key with a yellow indicator for it;
• Relay;
• Wiring. Choose an option with two copper conductors and double insulation, for example ShVVP2. A cross section of 0.5 mm is suitable, but if the lamps are powerful, 0.75 mm is better;
• Ground terminals;
• Female/male terminals - wide and narrow terminals.

It is not worth taking the mother-father complete with wires. It is better to crimp them using pliers when the wiring is already connected.

Pay attention to what kind of dashboard you have. If it is an old model, buy a set of fog lights for the VAZ 2110, and if it is a Euro dashboard, then it is better to use the PTF for the VAZ 2115.

As for the light bulb, 55V is more than enough power. We strongly do not recommend buying cheap fog lights, since their service life is very short.

Unexpected reasons for non-working PTFs on the VAZ-2110

But we will return to it later. There is still a lot that is still unknown in the design of foglights, relays, switches and lamps. For example, a possible reason for the failure of fog lights could be a completely unexpected breakdown.

First of all, we check the bulbs themselves; you can get to the left one through the hood.

On some versions of the VAZ-2110, a PTF from the Avtosvet plant (Kirzhach) was installed with a socket for the H1 lamp. Stock lamps are not the best quality and they do not like sudden changes in temperature.

It is quite difficult to get to the right fog lamp through the hood; it is easier to remove the headlight itself by unscrewing the screws.

During sudden cooling, when leaving the garage in winter, for example, or after turning off the headlights, the contact leg of the lamp bulb simply fell off the conductor. At the same time, visually the halogen lamp looked absolutely intact. It was enough to apply a plus directly to the leg itself, and the lamp would light up. The fault was due to poor-quality resistance welding, and it is almost impossible to detect the cause without a detailed examination of the lamp itself and its dismantling.

Of course, it is impossible to provide for all failure options, but we will consider the most common ones.

One fog light on VAZ-2110 does not light up

Scheme of work.

There may be plenty of options here. Apart from damage to the lamp itself or its filament, the picture is as follows:

1. Fuse. When correctly installing PTF on the ten, as a rule, they use the scheme presented above. As can be seen from the diagram, a separate fuse, F4 or F14, is responsible for the operation of each lamp. They are located in the mounting block, which is located in the niche of the front panel to the left of the driver. When replacing a fuse, we do not use bugs or jumpers, but only new fuses.
2. Ground contacts. In the case when, when installing the PTF, each of the headlights was connected to the negative separately, the loss of ground contact for each of the headlights threatens failure. We diagnose the lack of contact with ground either with a multimeter or by visually inspecting each of the contacts. If it is oxidized, we clean it and the place where it is attached and restore contact.
3. Lamp power contacts. In this case, you will have to check the integrity and condition of the contacts on the connection block both to the lamp itself and in the Ш1 connector on pins 6 or 1.

Two fog lights do not light up at once

If this happens, it is impossible to allow two lamps or two fuses to burn out at once. Most likely, the reason should be looked for elsewhere:

1. Oxidation of contacts on connector Ш1 in the mounting block. We remove the connector and evaluate the condition of the contacts. Just in case, check fuses F1, F14, F4.
2. PTF switching relay. We check the relay by pressing the fog light switch button. If we hear a click, the relay is working properly. If the relay does not click, it has failed or contacts 85, 86, 87 or 30 have oxidized. The relay can be installed normally in the mounting block, or in another place, at the discretion of the owner or the electrician who carried out the installation.
3. PTF power button. You can simply check it by closing contacts 6 and 7. If the relay works, the warning light and fog lights come on, change the button.
4. Oxidation of the ground contact of the PTF relay or the lights themselves.

General recommendations

And the power can be taken either from the ignition switch or from the side lights switch, which is undesirable, since you can leave the PTF on along with the lights on, and this will lead to battery discharge. Good luck with your search, bright and smooth roads!

Replacement example

Since all fuses are located in a common block, the replacement principle is the same for all. Therefore, we can consider an example of only one element that needs replacement. Let this be the cigarette lighter. It is designated F6 and F18 (see table).

The first priority before replacing a fuse is to check its functionality. Many people immediately change the element without even considering whether the problem of the unit failure really lies in it.

To check the fuse, you should perform several step-by-step operations:

• Start the car by turning the key in the ignition;
• Make sure that the cigarette lighter is inside its socket, where it should be;
• Wait about 20 seconds;
• Take out the cigarette lighter and check if it is warm. If the temperature remains the same, that is, the element is cold, then the fuse needs to be changed.

How to do it? Pretty easy.

1. Get to the panel on which the board with the relays and cigarette lighters is located. The mounting block is located, as you remember, to the left of the steering wheel, at the bottom of the dashboard.
2. By pressing the special latches, the cover will move away from its seat. Be careful not to break the latches.
3. The mounting block has now opened in front of you.
4. If you look at it carefully, you will see special tweezers on the edge. It is provided by the factory in order to carefully remove fuses and insert new elements in their place.
5. Remove the affected fuse. In this particular situation, we are talking about the cigarette lighter fuse, so you need an element designated F6 or F18.
6. This component burns out due to the fact that modern motorists need additional electrical equipment, such as vacuum cleaners and electric pumps. All this is connected to the fuse and overloads it. Hence the frequent breakdowns.
7. Using the same tweezers, insert a new fuse with the same parameters indicated on the mounting block.

If for some reason you don't have tweezers inside your black box, small pliers can serve as an alternative to this tool. Never try to remove the elements with your fingers. The nests are quite fragile, and with your hands you can only loosen it and damage it.

Replacing relays and fuses is a simple and inexpensive repair. But if you damage the block itself, then you will have to spend more, and you will definitely have to work hard.

Are fuses repairable? No. These are fusible elements that simply become deformed when burned. Therefore, repair is possible only in one option - replacing blown fuses.

The car is equipped with lighting devices, which are necessary for safe movement on the road and driving in the dark. Turn signals are one of the most important light signals. Serves to indicate when changing lanes, as well as to turn on the hazard warning lights. Quite often the VAZ-2110 fails. This happens for various reasons, which we will discuss in this article.
