How a rain sensor works on a car: how to check and adjust

July 15, 2016 Lada.Online 54 351 6

Many modern Lada cars (for example, Granta, Kalina, Vesta or XRAY) have a standard rain sensor, which is installed from the factory. On machines that do not have this option, you can install it yourself. Let's look at the features of connecting the DDA rain sensor on different Lada models.

How it works

It's logical to start with the question of how a rain sensor works.

For some reason, some are sure that the controller reacts to moisture that falls on the surface of the glass, and thereby turns on the windshield wipers, that is, the wipers, and also forces liquid to be supplied through the windshield washer nozzles.

But that's not true.

In reality, the operating principle is completely different. Even more complex, one might say.

This controller is not located outside, but inside the car. And it is logical to ask how then he can feel drops of water on himself. No way. It does not react to moisture itself.

The controller has 2 elements. These are photodiode and LED.

The LED's job is to emit infrared light. The human eye is unable to see it. But these same rays accompany us in everyday life and beyond. Just remember the TV remote control. The principle is the same.

Infrared radiation hits the surface of the glass, is partially reflected from this surface, and returns back. At this moment it is captured by the second element, that is, the photodiode. It records the amount of light returned.

If there is no water on the glass, that is, it is dry, a lot of light will return. When wet, the amount of light decreases noticeably, which is prevented by drops. Having determined that the glass is covered with moisture, the sensor automatically starts the windshield wipers.

Of course, the effectiveness of cleaning depends largely on how correctly you managed to choose wipers for your car.

The cars are very similar inside. And it’s impossible to say that Vesta is better than X-Ray. They have almost identical steering wheels, center panel design and seats. However, there are still differences. The interior of both models is well designed, all elements are well assembled. There are no squeaks or backlashes while driving. The seats are quite comfortable, however, on the rear sofa with the headrests lowered down, the seating position for passengers is uncomfortable, as they rest against the shoulder blades.

The interior of both models is equally good. It is very difficult to answer the question of which is better: Vesta or X-Ray. All elements are made from approximately the same materials. In terms of sound insulation, the differences are also minimal; it is at a decent level. The X-Ray is better here only because it is much more comfortable for tall passengers to sit in it due to the structure of the roof. It also has more luggage space with the seats folded down.

so the lever is 1 position up and there is an intermittent mode. the wheel on the lever changes the pause; stripes are drawn on it corresponding to the length of the pause. If the rain sensor is triggered during a pause, it turns on the wipers once or in constant mode.

I retrained the windshield wipers and it seemed that the rain sensor began to work normally. Or maybe he didn’t. In general, I also constantly work with my hands instead of this damn sensor.

I just rummaged around in the instructions. Settings for automatic wiper operation. This automatic wiper control function is set to the on state by default and remains there until it is turned off by the driver in the information display. If automatic wiper mode is disabled, the wipers operate intermittently.

That means it should be somewhere in the menu. I just haven’t dug that far into it yet. will seek.

For me, the rotation of the wheel steers with pauses between strokes. I'll be in the car and take a closer look at the settings.

Perhaps when replacing the windshield, something was changed from the factory settings.

Turning on the interior lighting on a Lada-Vesta car using a motion sensor.

Short tests of the previous design revealed small (glitches) spontaneous operation in sunny weather. Therefore, we decided to try another option, with a capacitive sensor. Of course, the initial sensitivity of the sensor of 10-15 mm was not satisfactory (to turn on the lamp you have to practically stroke it, that is, touch it with your hand). But by increasing the size of one of the plates (the sensitive element), it was possible to increase the sensitivity. Now the response distance is quite comfortable - 50 - 60 mm.

A few nuances for those who want to repeat the idea in their car.

These comments relate to the sensor itself and how to use it; by the way, a sensor from the Tolyatinsk company STATE was used: https://www.shtat.ru/shop/product-category/beskontaktnye-sensory-shtat-ts

1. The sensor is capricious in a very humid environment or in a situation where water runs along the plastic lining of the trunk lid. That is why using it as a trunk opening button does not always lead to good results. Sometimes it works on its own in snow or rain. Cases of opening at the sink have been recorded)).

2. Very frequent operations (namely, these happen in rain or snow, but this again only applies to using it as a trunk opening button) can lead to it hanging in the on position and, accordingly, to high consumption for the entire period of freezing. From experience (we measured the current consumption of a Lada-Vesta car with this sensor frozen in the ON state, used to open the trunk) is it approximately 400 mA? And this is a lot.

3. Using the sensor in the cabin has not yet led to the identification of any shortcomings, everything is clear and convenient. Testing has been going on for almost a week, under different conditions, day and night, both in a cold car and in a warm interior. Moreover, forced repeated switching on and off (that is, with a hand movement) never led to the sensor freezing, although when testing the device before installing it in a car, on a table, it was possible to catch a frozen state a couple of times. That is why we do not recommend connecting the sensor to constant power.

4. In the cabin, the sensor is connected via power to the ACC circuit (standard power supply for the interior lamp), which turns off in the car after about 2 minutes. Accordingly, even if you turn it on (the interior light) using the sensor and forget to turn it off when leaving the car, nothing bad will happen. After 2 minutes, the car will turn off the ACC itself and, accordingly, the sensor will be de-energized. And it is for this reason that you will not be able to turn on the lighting with a sensor if, for example, you spent the night in a car and woke up and reached out to turn on the light. The ACC circuits are disabled and the lamp will not turn on. Accordingly, the use of the sensor allows you to obtain convenient and comfortable control of the light in the cabin with the car running, on the road, in the parking lot while waiting for passengers with the engine running.

After playing with and testing the sensor in operation for more than a week, the same one was made for rear passengers.

Well, to complete the topic of using capacitive sensors in a car, one more video.

What are the rear view mirror covers for Lada Vesta needed for?

The devices significantly improve the aerodynamics of the car. Driving at high speed is not accompanied by an unpleasant whistle if the Lada Vesta mirror covers are installed. In addition, they give the vehicle an attractive appearance. The most popular are linings made using relatively expensive chrome. The overlays are body color, are installed on top of the standard ones and have a low price. They can be bought for 800 rubles.

Lada Vesta pleased with mirrors with good visibility. Everything looks very good. They also added a turn signal repeater to the mirrors, it looks very cool. Moreover, the repeater is made with a slight bend so that the driver, looking in the mirror, can see whether the desired turn signal is on. Another nice thing is that the mirror bends in the other direction, that is, if someone hits it, it will not break, but will bend in the other direction, and then due to the spring it will bounce back to its original place. This is all very cool. But there is also a significant drawback of these functional mirrors with good visibility. They creak terribly when folding, especially when you park the car at night in a quiet courtyard and you start folding them in complete silence, the grinding sound is heard throughout the entire area, it is very unpleasant at such moments. You don’t fold mirrors, you close them like closing a barn door. Moreover, it happened two times that the mirror on the passenger side did not fold the first time; when it was completely bent, for some reason there was no click that fixes it in the folded position. It only worked from the second to the third time. I don’t know, maybe it was something that froze, but now everything seems to be working. Also, if you tap the mirror with your finger, you can hear the rattling and ringing of the spring inside, which is also sometimes noticeable when driving on a ribbed surface. The emptiness inside intensifies this ringing significantly.

Exterior

In terms of appearance, a lot will depend on personal preference, as designs vary significantly. X-Ray is definitely suitable for those who like a cocky and aggressive look. Of course, the production hatchback doesn’t reach the level of a chic concept car, but it looks great.

In its style, one cannot help but pay attention to the stampings on the body, which catch not only the doors, but also the fenders and even the bumpers. However, these ornate curves in the shape of the letter “X”, together with the 15-inch wheels that come as standard, and the impressive ground clearance, visually make the car shorter, and not everyone likes it. However, one cannot help but admit that the muscular body shapes, feet, headlights, chrome and trims look very advantageous.

As a result, they got a pretty and moderately correct image, which, on the one hand, does not have any features that break out of the overall picture, and on the other, never gets boring. A wide radiator grille, sharpened headlights, short overhangs and a line of side glazing extending upwards combine perfectly with branded lining on the front fenders and nice wheels.

How to remove a rear view mirror

Mirrors of this type are designed to study the situation on the road behind the car. They can be divided into two categories:

• salon - installed inside the car;
• side - located on both sides on the front door pillars.

The interior mirror is located inside the car

side mirrors are located on both sides of the car

It seems that it could be easier than dismantling the mirror? In fact, this is not so easy to do, and the principle of dismantling can vary significantly between different brands and models. We will tell you about the most universal methods of removing, disassembling and installing internal and external ones. However, if any of the methods described here do not work for you, check your machine's owner's manual. Today, many automobile companies make all such processes much easier: perhaps, instead of unscrewing bolts and bending terminals, you only need to press a small button or pedal.

Required Tools

In order to remove the mirror, you do not need any specific or hard-to-reach tools. As a rule, everything you need can be found in any motorist’s garage.

• a set of screwdrivers (most likely, only figured and flat ones will be useful);
• wrench depending on the size of the bolts;
• household hair dryer for removing the mirror element.

Add to this set skillful hands and the desire to do everything efficiently, and you can get down to business.

Salon

Interior mirrors can be installed in a variety of ways depending on the make, model, and year of your vehicle. There are two methods that are used most often.

1. Installation into the car ceiling using bolts or self-tapping screws.
2. On the windshield using glue or suction cups.

Thus, on many domestic cars the assistant device is installed using ordinary bolts, which greatly simplifies the dismantling process. To do this, you just need to unscrew the bolts after removing the plug.

in order to remove such a mirror, you just need to unscrew the bolts

The situation can become more complicated if the mirror is mounted on a bracket glued to the glass. First of all, check whether it is possible to separate the bracket itself and the platform glued to the glass. On most cars, they are separated by moving the clamps or turning in a certain direction.

If this is not possible, you will have to resort to a radical method and remove the bracket along with the windshield. The fact is that the glue holds the elements very firmly, so when you try to separate the mirror, you may accidentally damage the glass.

You most likely will not be able to separate the bracket platform from the mirror on your own, so it is better not to risk it and contact a special salon. Especially if you are dismantling it for future tinting. However, if you decide to do it yourself, be prepared that a trace of glue will remain on the glass.

Side left and right

Side mirrors are divided into two categories:

• with mechanical drive;
• with electric drive.

On almost all cars, you will need to remove the door trim to get to the mounting screws. You can find out how to do this on your model in the instruction manual.

This is what a car door looks like with the trim removed

Next, to remove a mechanically driven part, you need to follow a certain procedure.

1. Remove the regulator locking bracket.
2. Unscrew the fastening screws on the inside of the door.
3. Remove the mirror.

Video: dismantling the side mirror

If the mirrors are electric, the procedure will be slightly different.

1. Disconnect the negative terminal from the battery.
2. Disconnect the block from the wires.
3. Unscrew the fastening screws on the inside of the door
4. Dismantle.

Diagnostics of device health

This is done by analogy with the Priora, but on the devices of the Lada Vesta there is no button that needs to be held.

Diagnostic instructions:

1. Press your finger simultaneously on the two buttons on the right switch under the steering wheel.
2. Turn on the ignition.
3. All indicators and lights on the devices should light up, the arrows will deviate to the maximum position and move back.

4. Then press the top button of the same switch. This turns on the “Soft” mode. On the right is the firmware version of the electronic unit.

Varieties

Like many other systems, the automotive lighting sensor comes in several varieties. Some of them are available for purchase and self-installation, while others are found only in the factory equipment of the vehicle:

• A standard sensor can be purchased at an affordable price and installed yourself. The sensor is fixed in the passenger compartment in front of the windshield of the car, followed by connecting the relay and electrical wiring. The functionality includes adjusting the mode and intensity of the vehicle's headlights.
• A built-in light sensor is more often found in expensive foreign cars, where it performs a wide range of functions. In addition to the standard tasks of turning on and adjusting the headlights, the device can adjust the lighting inside the cabin and on the dashboard.
• The combined light and rain sensor is one of the most expensive models of automotive sensors, combining the functions of controlling lighting and the operation of windshield wipers. The rain sensor detects precipitation through photodiodes and photocells, instructing the wipers to begin wiping the windshield. Depending on the intensity of precipitation, the sensor can also activate the headlights, reacting to heavy rain or snow.

Versions of Vesta X-ray, from the most modest to the most expensive

The new Lada is in no way inferior to its classmates produced by any other global auto giant.

Its internal electronic filling includes a high-end audio system, a set of airbags, air conditioning, as well as many other pleasant little things, the number of which is constantly growing, depending on the version of the car purchased.

By the way, I finally installed an alarm transmitter on my brainchild, working on the basis of the Era Glonass system, which, in the event of an accident, will send a message to rescuers, which will contain the coordinates of the accident site.

And now in more detail about each version of this car model.

Design and operating principle

Considering that this device can be part of the factory equipment, the light sensor is manufactured in the format of a small compact housing for installation in the appropriate position in front of the windshield in the vehicle interior. The electronic product consists of several photosensitive elements and an LED, which are sufficient for the sensor to quickly and reliably respond to changes in time of day, weather conditions, turning off street lights, or entering and exiting a tunnel. Having detected changes, the device sends a signal to the control unit, whose relay turns on the low or high beam headlights.

Using a light measuring device allows the driver not to be distracted while driving by adjusting the headlights. However, the functionality of this device also has its downsides, because many car owners get so used to the operation of this device that they lose the habit of independently controlling how the headlights on their car are turned on and off. Sometimes this turns against inattentive drivers who forget to turn on the high beams in the daytime during fog and other conditions that are not intended to be detected by the light sensor. On some brands of cars, these devices are capable of operating regardless of the engine ignition, which leads to unpleasant situations when the car’s headlights come on while parked at night, thereby draining the battery.

Reviews

Rain and light sensor Ford Focus

Gentlemen, there is a spot on the windshield like a rain and light sensor, although maybe I’m wrong. But my lights turn on as soon as I start the car and I have to turn on the wipers myself. Maybe I’m wrong or is something not working correctly?

to s040os: It could also be a climate control sensor. You can simply check it, take a bottle of water and pour it on the windshield in the sensor area, the wipers should turn on automatically.

they don't turn on

to s040os: Are you sure that this speck is the sensor? It may not turn on the windshield wipers itself, but it can adjust the pauses between wipes depending on the intensity of the rain and the speed of movement. Turn on intermittent mode during rain and check.

With light. Do you have an AUTO position on the light switch? Perhaps your car already has a Scandinavian lighting scheme and the low beam headlights automatically turn on when you start the engine.

there is an auto sign but it doesn’t switch there and my assembly is Spanish so if so

The swing cycle regulator is located on the wiper switch; you can turn it and adjust the cycle

As far as I remember, the Spanish assembly already has Scandinavian light. And don't worry about the wipers. I have a 2009 FF2, so the instructions clearly state that the rain sensor works by turning on the intermittent operation of the windshield wipers. Moreover, on the power lever there is a roller for adjusting the sensitivity of this sensor.

to vitalek01: Thanks for the feedback, it seems that the cycle itself will be determined by the degree of humidity.

to mATr1xX: So this is how to adjust the sensitivity of the rain sensor. The more sensitive it is, the more often the wipers will work.

Thanks for the clarification guys I'll try

to s040os: Afterwards, let us know what happened and how it happened, we’ll wait.

Good afternoon Regarding the wipers, I can say for sure (I have a Spanish assembly from 2008, bought in 2009) for them to work automatically, the switch needs to be switched to intermittent mode and when water gets on the sensor they will work, and the regulator adjusts the degree of moisture at which they will trigger. However, in dry weather and especially in winter, I turn the switch to the off position, since the wipers may work unexpectedly due to some condensation on the glass, for example, fog. As for the light, mine has a switch position in the car and only in this position does it turn on automatically; perhaps your car has “daylight” installed, which turns on immediately after starting the engine.

to Anatoli_G: Well, that's right. That's how it should work.

to Anatoli_G: Thanks for the additions.

Good evening, please tell me the rain sensor has stopped working, it used to work. Now when I move the lever to the position for the sensor to work, the wipers wave once and stop, then I move the lever to the constant operation position, the wipers constantly work when I’m just driving, as soon as I stop they start working intermittently. please tell me what could be?

Greetings! My name is Mikhail, I want to express my gratitude to you and your site.

Thanks to you, I was able to remove the scratches my wife caused in the parking lot on my own.

It all started when my wife passed her license and began to often take my car to get to the nearest shopping center. There were no signs of trouble, but one day she said with tears in her eyes that she had rubbed herself against a pole in the parking lot. I still don’t understand how it was necessary to manage to do this, but with women everything is possible, you understand)) The scratch was deep enough, but there was no money or time to bother with painting. That's why I simply ignored the scratch.

A week ago I came across Artem Shevchenko’s blog, who in his article told how to get rid of scratches in 10 minutes. At first I didn’t believe it, but I decided to try it anyway and didn’t regret it at all. The method worked 100%, there was not a trace left of the scratch, and nothing was visible at all from any angle.

In general, I’ll keep the intrigue, for those who want to quickly get rid of scratches, come and read the article on Theme’s blog, I guarantee you won’t regret it.

Lada Vesta from the ZR park: testing all available options

Our Luxe sedan is equipped, by class standards, very generously. And skeptics are probably sure that all this wealth is mercilessly buggy. I hasten to disappoint them.

LADA > Vesta

I have repeatedly heard and read the opinion that, they say, only expensive cars need all sorts of bells and whistles, while a budget car should be without any frills.
On the one hand, a logical explanation for this approach is not difficult to find: the simpler the design, the higher the reliability. And this parameter is almost in first place for inexpensive cars. But let's not forget that we live in the 21st century, and the criteria with which we approached Zhiguli and Samara three decades ago are, to put it mildly, outdated. In addition, our market has not been closed for a long time, and competitors are not shy about offering all kinds of options. So, in my opinion, AVTOVAZ’s policy of saturating its models with additional equipment is correct. After all, not everyone chooses a car just for its willingness to serve for years without breakdowns. Today's buyers look at the design, the equipment, and the level of comfort. I'll start with the climate system. It has eight fan speeds and 15 temperature levels. Domestic models have never offered such wealth before! Each person has his own concept of a comfortable microclimate, and Vesta will probably satisfy everyone. You only have to play with the settings at the beginning of the trip, and on a long journey there is no need to touch the knobs. And this is the best compliment considering that our car has a regular manual air conditioner (now the top version already sports single-zone climate control). The system works very efficiently for cooling, and subjectively turning on the compressor does not affect the dynamics of the car.

Male colleagues like to reproach the fact that all Ladas are still content with single-stage seat heating. They say you can’t set a comfortable temperature. However, I don't see a problem with this. Driving with the heater on all the time is harmful to men's health. Therefore, there is no need to play with the degree of heating: turn it on after starting the engine, enjoy the effect for the first ten minutes, the most unpleasant in winter, and turn it off. Vesta warms up both the fifth point and the lumbar area well. According to rumors, the station wagon will also have heated rear seats - an unheard-of sybaritism for the Lada, which not all competitors have yet.

Expecting something supernatural from the audio system of a $10,000 car is stupid. Therefore, we will ignore the issue of sound quality. To my non-automobile taste, the Vesta is no better and no worse than those of its foreign-car classmates. Otherwise, the head unit in the flagship Lada is decent. The display correctly displays Russian tags from external media, the speakerphone works well, and the Bluetooth connection is reliable. For comparison: the multimedia in the Nissan Almera was very selective with smartphones, and wireless synchronization periodically failed.

Special thanks for the large control keys. Nowadays, almost everyone has standard double-din audio systems, but for some reason this does not always mean successful ergonomics. Often, creators prioritize the beauty of a large display, which is absolutely useless in the absence of navigation or a rear view camera. Vesta’s priorities are correct: it’s easy to get to the right button without looking, and two lines on the screen are more than enough to display the necessary data.

Some may regret the lack of a CD player, but let's be objective: this format is becoming a thing of the past. It is more convenient to use SD cards and USB flash drives. It’s much easier to record and re-record music on them, they don’t take up any space at all, and they hold so much data that you won’t be able to listen to everything in every “long-distance” trip.

There is one complaint about the light sensor: it would be nice to parallel it with the windshield wiper switch. Rain and snow reduce visibility by definition. This means that working wipers should be a signal to turn on the low beams. Now in bad weather you have to turn on the headlights manually. However, there is a way out. On Vesta, the lights go out completely after the ignition is turned off. You can set the switch on the left steering column lever to the low beam position and not touch it anymore: the battery will not run out and you can forget about manually controlling the headlights.

Interior dimensions of the domestic model

Thanks to the impressive size of the body, the Lada Vesta managed to acquire a fairly spacious interior. Here, on both seating rows, five people of average build can sit with sufficient comfort. Trips over long distances with such a large number will proceed with comfort and in an unnoticed time.

The developers paid great attention to such an important dimensional parameter as the height inside the LADA Vesta cabin. Thanks to this, Vesta has increased the amount of space between the seat cushions and the roof lining. Tall passengers will feel quite comfortable after boarding

Also, now there is no risk of catching your head on the edge of the doorway while “immersing” in the cabin

Tall passengers will feel quite comfortable after boarding. There is also now no risk of catching your head on the edge of the doorway while “immersing” in the cabin.

The length and width of the Russian model had a beneficial effect on the amount of space available for placing the legs of the rear riders. The distance from the back of the front seats to the passenger’s knees in the rear seat row is an enviable 200 mm. Even people 2 m tall will not be able to rest against the front backrests.

Main differences between the models

The main difference, judging by the reviews, between the Lada-Vesta and the Lada-X-Ray is that the sedan is a car developed completely from scratch. Its development lasted for quite a long period, but people started talking about Vesta already in the early stages of construction. The model is popular because people have been waiting for its appearance for a long time. With regards to X-Ray, we can say that it was not developed from scratch. The model was based on the no less famous Renault Sandero model, and it was built on the basis of the Logan, which has been tested over the years by many taxi drivers in Russia.

In this case, people get confused in their choice. They think about what is better to choose - new developments and sensations or a reliable platform that has long proven itself to be good. So far there are no exact answers to this dispute. All differences will be discussed in more detail below. Which is better - Vesta or X-Ray?

How to remove the side mirror on a Kia Rio?

Removing the side mirror is a little more complicated; you will have to use tools, but there will be no differences in the removal process between the left and right housings. For dismantling you will need:

• flathead screwdriver;
• head at 10.

The housing is removed in the following order:

• turn off the Kia Rio engine;
• Remove the negative wire from the battery terminal;

• use a slotted screwdriver wrapped in electrical tape or a plastic spatula to pry off the housing lining;
• press out the strong plastic clips (this will require some physical effort) and remove the lining;
• With your fingers (preferably with gloves) squeeze the latch holding the block of wires responsible for heating;
• move the block to the side;
• holding the element with your left hand, use your right hand to unscrew the three bolts holding the mount using a 10-mm wrench;
• remove the part.

Installing the mirror is done in the reverse order. When working, you must use gloves and do not touch the reflective element with your hands, so as not to leave marks that are difficult to wash off.

Which rain sensor is suitable for a Lada car?

Disassembling rear view mirrors

The procedure below applies to both exterior and interior mirrors.

1. The mirror is removed from its regular place.
2. Use your hand to gently press the top edge of the mirror glass until it unrolls.
   Side mirror mirror element rotates manually
3. A piece of rag or napkin is placed in the gap that appears between the mirror body and the glass.
4. Then a flat-head screwdriver, pre-wrapped with electrical tape, is inserted into this gap.
   The latches holding the mirror element are bent with a flat screwdriver
5. The latches holding the mirror are pryed with a screwdriver and removed from the protrusions.
6. The mirror glass is carefully removed.

A little about the multimedia radio

The music system works without problems, nothing slows down. People ask how to make the screen display the climate control and door opening. To do this, you need to buy a special device and connect to it. Then the display will show the operating parameters of the climate system and doors.

The steering wheel was covered with braid, which was ordered from a well-known online store. We bought the seat covers there.

Popular worlds

Finally, I would like to talk about several popular myths that are associated with rain sensors on cars.

Indeed, many continue to believe in them. And this can become a problem in certain cases.

• Rain sensors are available at extra cost. In fact, these controllers are becoming standard equipment in many countries because they are directly related to safety. Although it happens that the first version of the car did not have them, and after the restyling took place, the sensor appeared in the basic configuration. This is simply due to the automaker meeting new requirements;
• The controller reacts to falling raindrops. This issue has already been addressed. No, it reacts not to moisture, but to refracted light;
• The system does not work at night. Infrared radiation is completely independent of outdoor lighting. Based on this logic, the TV remote control wouldn't work at night either;
• If the glass is directly replaced, the sensor will no longer be there. Also a myth. But conditional. It all depends on the specific glass. Most modern glass comes with space provided for this system;
• You cannot apply tint on the glass in the area of ​​the sensor itself. Actually it is possible. But it’s better to cut a small hole for the controller;
• In winter this is a useless feature. If the glass is heated, that is, the snow turns into water, then the function works exactly the same as in spring, summer and autumn.

Power plants

When comparing the Kia Rio and Lada X-Ray, it’s worth saying a few words about the engines.

The Kia car comes with the following power plants:

1. 4 liter petrol engine with 107 horsepower.
2. 6 liter engine with 123 horsepower.

The first installation option is installed on budget versions of Korean cars. The 107-horsepower engine accelerates the vehicle to 100 kilometers in 11.6 seconds. The maximum speed is 185 kilometers per hour.

Special mention should be made of the very low fuel consumption, which when driving around the city does not exceed 8 liters per hundred kilometers.

The older model of the Rio car's power plant, complete with a 123-horsepower engine, is equal to 190 kilometers per hour. The increase in engine displacement had a slight effect on fuel consumption.

When driving around the city, the power plant empties the fuel tank by 8.5 liters per 100 kilometers traveled.

Domestic engineers equipped the Lada X-Ray with the following units:

• 6 liter petrol engine with 106 horsepower.
• 8 liter petrol engine with 122 horsepower.

From the comparison it is obvious that, despite the larger volume, AvtoVAZ engines could not compete with their Korean counterparts. The Kia Rio has similar dynamics to the Lada X-Ray, but at the same time consumes significantly less fuel and develops a higher maximum speed.

We disassemble the mirror to replace the Vesta turn signal

Theoretically, to replace the turn signal, it is not necessary to completely remove the mirror from the car. And yet the work is not so difficult that you need to change the turn signal and deal with fragile plastic in the canopy. Therefore, it is safer to remove it. Then we proceed according to the following algorithm:

Using a thin screwdriver, unclip the latches one by one and remove the mirror from the housing. If the glass is heated, disconnect the two terminals on the thermoelement. Now we have access to the mirror adjustment gear motor. The location of the clamps is shown in the photo.

To replace the turn signal, you need to remove the upper part of the outer plastic mirror cover. It is also secured with latches that need to be pryed off with a thin flathead screwdriver. The location of the latches is as follows:

Important! Attention! Before working with the plastic elements of the side mirrors, they must be warmed up with a hair dryer turned on at a temperature of 100-120 degrees at medium blowing power

We remove the cover and gain access to the direction indicator. It is fixed in plastic sliders and is protected from shifting by latches. We release the latches and move the pointer for dismantling.

We inspect the quality of the contacts on the terminal block. It is possible that the turn signal does not work due to oxidation of the contacts, although theoretically they are insulated from moisture with a rubber boot. Water can only get there due to the negligence of the collectors.

Disconnect the terminal and remove the non-working turn signal

We install the new one in the reverse order, being careful, and before installing the decorative cover, we check the functionality of the pointer by connecting the terminal to the battery

Characteristic symptoms of malfunctions

How does a rain sensor work?

The operating principle of the rain sensor is based on a comparison of the optical properties of the windshield under different atmospheric conditions, or more precisely, on the differences in the reflection of an infrared ray by a clean and moistened or contaminated glass surface.

Everything is quite simple - it consists of emitting and receiving infrared LEDs. The design and operation of such a product will help you understand the photo:

As can be seen from the above description, the structure of such a device is quite simple, which predetermines quite wide possibilities for its use.

What such a device looks like is shown, for example, in the photo:

The video will help you understand how this kind of work is done. The data presented confirm that it is easy to glue such a device, and this work can be done yourself.

Review of Manufacturer Prices

Conclusion

The process of replacing a rain sensor yourself is not at all difficult, but it requires care on the part of the repairman. Do not violate the manufacturer's regulations. When laying the wiring, be extremely careful not to damage the insulating layer. A short circuit to ground will damage the digital controller.

Windshield pillar trim

You need to open it, lower the window, disconnect the terminals from the battery. Then disconnect the connector with wires. To do this, you need to pull its lock up. The part is ready to be removed from the hinges.

Tip: If the door is being removed for repairs that require disassembly, it is recommended to disassemble it while it is on its hinges. This is easier to do thanks to free access to both sides of the door.

The casing is removed to repair the mechanisms that are installed under it, or in case of some modification. The tools you will need are a flathead screwdriver and a socket wrench with a T20 (star) bit.

The following sequence of actions is performed:

• Remove the side mirror triangle. The part is pryed off with a screwdriver and the latch is snapped off. Then disconnect the block with wires;
• The doors are pryed up from the bottom, then the lampshade is removed and the wires are disconnected from it;
• Using a wrench, unscrew the three screws securing the casing from below;
• They find a plug from the top end and take it out. Unscrew the fastening screw that is screwed in behind it;
• Another screw is found and unscrewed inside the door handle;
• Carefully pry up, remove the unit that controls the exterior mirrors, power windows and central locking, disconnect the wiring from it, unscrew the fasteners located perpendicular to the door part;
• Starting from the bottom, insert a screwdriver between the door and the trim until all the latches are released.

Remove the window handle. To do this, insert a screwdriver or a spatula between its middle mount and the bottom washer, and pull the protrusion on the middle part outward. When the protrusion is pressed out, the middle part is pulled out. Then remove the handle from the slot of the window regulator, the base of the handle, and the round plastic washer.

Insert the tool between the door handle and its trim, then remove the trim. There are two bolts screwed in under it, which we unscrew with a wrench. At the very bottom of the card, find a self-tapping screw and unscrew it using an asterisk attachment. Now the casing is fixed only on plastic clips and velvet. The card is pryed up, starting from the bottom, and all the latches around its perimeter are snapped off. Then remove the card from the velvet.

The side window trim is attached to the rear parcel shelf trim. This trim is removed together with the rear parcel shelf upholstery.

Elements of the ventilation and heating system

The stove body (in Fig. No. 5) is located in the car interior under the instrument panel frame. Inside the case there are:

• heater radiator;
• electric fan;
• fan speed controller (RFV) or additional resistor;
• air flow distribution damper;
• gear motor that regulates the dampers;
• air filter.

The heater radiator releases heat to heat the interior. Located inside the case on the left side. To replace it, you will have to remove the upper frame (lining) of the panel (dashboard).

An electric fan forces air into the car interior through air ducts. It is located on the other (right) side of the body. Access to it opens after removing the glove compartment.

The additional resistor is designed to regulate the rotation speed of the fan motor. It is installed on the heater housing on the driver's side.

The cabin filter cleans the air entering the cabin. Located in the heater block on the passenger side. It is replaced from inside the car (and not from the engine compartment, as on Grant, Kalina or Priora). In addition, the filter element resource is 30,000 km, and not the usual 15 thousand km.

Air ducts run from the stove body, which direct air flows to the windows, into the interior and legs. The central deflectors can adjust air flow in different directions, and its strength is controlled using a horizontal wheel underneath them.

AvtoVAZ has implemented airflow for the Vesta driver’s feet in a new way. The air duct nozzle is located not on the side, but above the foot of the right foot. Some owners of the new sedan believe that this design is not very successful, because It warms the toes worse than the foot itself. For the front passenger, the air duct exits closer to the wall of the engine shield and a similar situation will not arise.

How to turn on heated mirrors

Starting in 2022, AvtoVAZ has equipped the 2180 with the additional function of “electric drive and electric heating of side reflectors.”

This function is activated only after starting the engine (so as not to damage the battery) and switching on the heater to the window blowing mode (windshield and side). After this, you need to press the button on the climate console, which is responsible for heating and blowing the reflectors, rear and windshields.

To activate this function on the luxury version of Lada Vesta, you need to press the leftmost button at the bottom on the car’s climate control unit with the inscription “MAX”.

At 20-degree frost (which is usual for an Eastern European winter), the following happens:

1. after 1 minute the ice on the reflectors begins to melt;
2. after 2-3 minutes the ice melts completely;
3. after 4 minutes the mirror is clean and dry.

Setting up the central locking

Immediately after purchasing the Lada Vesta, the central locking program was not configured on it. The doors do not close automatically when driving. They can only be closed manually by pressing the button shown in the photo.

How to program it? The procedure is as follows:

1. Start the engine or simply turn on the ignition.
2. Press the central locking button and hold for several seconds (5 s) until a sound signal appears (the buzzer will beep once).
3. The automatic central locking system has turned on.

You can check its operation like this. You start and drive, and you hear a click on all 4 doors. The locks closed automatically. When a certain speed is reached (7 km per hour), the central locking function is activated. To disable it, you need to repeat the steps. In this case, the buzzer will beep not 1, but 2 times. Maybe many drivers are already familiar with it, but we only found out recently.

How to disassemble a side mirror on a Lada Vesta

To disassemble the side mirror at 2180, you need to do several simple manipulations. Since the Lada Vesta turn signal indicator is an electrical device, when removing the reflector it is necessary to remove the negative terminal from the battery. It is necessary to remove the trim from the car door pillar by first unclipping the upper and two lower latches. After this, you need to disconnect the wires and unscrew the three screws that secure the rear view reflectors to the door.

Once the reflectors are removed, their disassembly is almost complete:

1st step: turn the mirror element to the side until it stops to remove it (the reflector heating wires do not need to be disconnected);

Step 2: use a flat-head screwdriver to unclip the mirror element from the housing;

Step 3: To release the colored plastic trim clips, use a flat-blade screwdriver and then slide the trim to the side.

If you remove the side mirror, you can get to the mechanism that provides electrical power to the repeaters. After replacing the relevant parts, installation proceeds in the reverse order.

Dismantling

Self-installation of a washer level sensor on a Lada Vesta begins with dismantling the tank. First you need to remove the plastic frill near the windshield.

First we remove the Vesta frill

Vesta's frill is made in the form of a single piece, and therefore it will have to be removed completely. To work you need the following tools:

1. Ratchet;
2. Head 17;
3. Torx T20 sprocket.

First you need to remove the hood seal, then pry up and remove the plastic decorative caps at the base of the wiper holders to gain access to the nuts. When this is done, you need to unscrew the nuts and remove the wipers - you need to work carefully so as not to inadvertently tear off the slots on the seats.

Next, all that remains is to unscrew 6 screws (3 on each side), using a Torx T20 sprocket, and remove the frill.

After this, access directly to the tank opens, which needs to be removed. This is not difficult to do, since it is secured with just one bolt. The situation is a little more complicated with the plug, as well as the washer pump hose. To disconnect the plug, pull up the blue flag.

Installation

To install and connect a light and rain sensor in a car, it is not necessary to seek the services of a workshop. Each set of sensors comes with detailed instructions describing the installation procedure. In most machines, the sequence of user actions is equally simple:

1. The main component of the device, called the “eye,” is fixed inside the passenger compartment in place of the rear-view mirror holder. Considering how the light sensor works, for greater accuracy of the sensor, it is recommended to point it towards the driver and not towards the street. The dimming in the cabin is fixed much faster and more reliably.
2. The sensor relay and control unit are connected in accordance with the diagram from the instructions.
3. The last to be connected are the contacts responsible for adjusting the car's lighting. Some sensor models provide the ability to connect a button to turn the light and rain sensor on and off.

Sensor design, operating features

A light sensor (hereinafter referred to as DS) is a microcontroller board in a plastic housing. In the center of the module there is a lens for “capturing” the light flux (photocell).

The operating principle of the DS is as follows: when the switch lever is in the “Auto” position, the sensor determines the brightness of the light beam. As soon as the actual brightness indicator is below the “programmed” range, the low beam and dashboard lights are automatically turned on.

The DS is automatically deactivated when the brightness level increases.

Description, installation, operating mode

A digital rain sensor (hereinafter referred to as DD) is installed on Lada Vesta cars in the “Lux”, “Exclusive”, “Comfort” trim levels.

In budget models, “gadgets” are provided as optional equipment. The DD is designed to activate the windshield wiper drive when water or snow gets on the surface of the windshield.
