Continue on the car with a burning ABS icon can be, but you need to understand that the anti-lock system will not work normally.

In winter, an ABS failure can lead to the "YUZOM" brake, the blocking of the wheels and the drift of your Renault. Therefore, it is important to find and correct the reason why the lamp caught fire.

How the system worksABS fine

Recall that ABS - Anti-Lock Braking System - In the car prevents wheel lock and consists of a system of sensors that control the speed of the machine and rotating its wheels, as well as the hydraulic unit and the control unit. The control unit processes the signal from the sensor, the hydraulic unit distributes pressure on the brake pads.

The main task of the anti-lock system - So change the pressure in the brake system highway so that on the basis of data on the speed of rotation of the wheels, the car could urgently slow down, and at the same time maintain controllability.

Modern ABS systems are reliable and often work in a pair with EBD system, which distributes brake efforts. The most vulnerable point in the anti-lock system is a wheel sensor, because it is constantly subjected to pollution and shocks, for example, when repairing the wheel hubs.

The fact that the ABS system works in your Renault, you will understand when with intensive braking on slippery coating, the brake pedal will begin to vibrate (keep in foot, twigs and jerks), and a characteristic cracking will be heard.

Why an error appearsABS

Normally, the abs light bulb lights up immediately after starting the engine and drove after a couple of seconds, when the bornecomputer checks (and approves) the operation of the system itself.

If the light lights up while "Renault" in motion, or does not go out soon after starting the motor, the reason may be that:

• aBS fuse blocked
• the ABS wheel sensor has failed due to mechanical damage or change the gap between the sensor and the gear rotor
• contact with the sensors of the system is lost - the wiring broke out, the terminals were oxidized
• the voltage in the onboard network fell below 10.5 V (sat down the battery, the generator does not work, etc.)
• hydromosos electric motor failed
• the hydroclap or the ABS control unit (rare breakdown) failed.

The ABS lamp can also light up after the illiterate repair of your Renault due to the inept actions of the wizard, which damaged the sensor or wiring.

What to do if ABS light caught fire

In order to prevent problems in the ABS system, you need to constantly monitor the health of the battery, the generator and the relay controller. The ECU of the anti-lock system strongly reacts to voltage drops. The normal operating voltage is 12-14.2 V.

If the ABS control lamp caught fire on your "Renault", the search for the fault is worth Start with fuses.

Then you need to examine the integrity of the wheel sensors, check the wiring. Often the cause of the fault is the oxidized sensor connector or the steady wire.

• If the ABS icon caught fire on the Renault dashboard after the recent replacement of brake pads or hubsmaybe the wizard forgot to connect the ABS sensor connector. Or he needs cleaning from dirt.
• If the icon lights up after a long slip, just a few times intensively slow down - and the icon will go out. In this case, this is the normal reaction of the anti-lock system on the Renault System.
• If the ABS lamp goes out, it flashes again - The reason you need to search in the contacts of the sensors.

You can check the current leakage from the onboard network, armed with a multimeter.

After you find and eliminate the problem, do not be lazy to check the operation of the ABS system with a simple test: turn away up to 40 km / h and pull the brake pedal sharply. Pedal vibrates and "crunches"? So everything works as needed.

If the icon does not go out and after troubleshooting, refer to computer diagnostic specialists to determine the error code on your "Renault" - and eliminate it (or reset).

• Why turn turns on "Renault", we wrote

Find out the reasons why this light bulb lights up, as well as what measures to do.

Driver's dashboard is your tip and a great assistant in the right, high-quality and smooth operation of your car. If no error light is lit on the dashboard - then there is no reason for the experiences.

However, if one of the lights caught fire on the tidy, especially if this is a red error light, then you should immediately contact the car service. And it will be better if you no longer have a car and go to the car service on it, and deliver your cars to the masters with the help of a tow truck.

Why caught fire ABS light bulb?

The ABS system in the car is responsible for high-quality braking. In all modern cars, special electronic control units are installed, which help the machine to stop (brake) correctly, competently, efficiently. The ABS system helps in emergency braking, and in braking during the rotation (anti-quasin), and in braking on slippery surfaces. Without ABS, the operation of the car would be much more dangerous.

And once the ABS light was caught fire - it means that something happened to the smart braking system, something went wrong. And perhaps the brakes may not work at all - refuse to refuse the most inopportune moment!

Why the abs light bulb on the instrument panel is burning, and what to do in such a situation

The anti-lock system is installed in almost every modern car, and it helps drivers to avoid blocking the wheels. ABS machines provide maximum brake system efficiency, which reduces the length of the braking path. To diagnose the operation of the anti-lock system, the driver has a special indicator on the instrument panel. When it lights up, the computer computer systems warn the driver that the ABS currently does not work, and the blocking of the wheels is likely to press the brake pedal. An anti-lock system, if a car is equipped with a car, it is necessary to maintain in working condition, besides, there are not many reasons why the ABS light is burning.

How the ABS state indicator should work

The ABS system can be divided into several functional blocks so that it is easier to understand the problem, due to which the corresponding indicator on the instrument panel lights up. Note that the anti-lock system consists of:

Rotation Sensors. Usually there are 4 pieces - one on each wheel; ABS module; Devices for monitoring the correct operation of the ABS module; ABS indicators on the instrument panel.

If the anti-lock light bulb on the instrument panel caught fire after the engine start or during the movement of the car, then the ABS system is disabled. Many drivers mistakenly believe that with the ABS activated light bulb they have problems with the braking system, but it is not at all. For the diagnosis of brakes, the corresponding indicator corresponds to the car.

In the first seconds after the start of the engine, all indicators should light up on the instrument panel. If at this moment the light bulb is not lit, it means that it is faulty.

Why the abs light bulb is burning

Based on the ABS device, you can come to the conclusion that the system malfunction indicator can for the following reasons:

Problems with sensors installed on wheels; Malfunctions in the ABS system control unit; Faulty cables between elements transmitting information about their state; There are problems with a crown on the hub.

All described faults can manifest directly during movement. For example, vibrations on an uneven road often lead to wire cliff. During traffic off-road to sensors, the dirt may be poured or the sand will be scored in them, which will not allow them to transmit faithful information to the system control unit, and it will notice a malfunction on the ABS light bulb on the instrument panel.

ABS light bulb caught fire: what to do

The surest way in a similar situation is to use diagnostic equipment that will allow you to determine which sensor the signal is not transmitted to the control unit and what errors are available in the ABS operation. If it is not possible to check the car on the diagnostic stand, you can take the following actions:

To accelerate on an even straight line of the road to 40 kilometers per hour, and after sharply press the brake pedal. If the light bulb is survived, it means that the anti-locking system returned to the operating mode, eliminating a temporary malfunction; In the case when the ABS light bulb lights up on the road for a while, and then goes out, it is necessary to carefully check all wire connections that are included in the transmission of data on the functioning of the system. Most likely there are problems with wires and contacts; If the problem of the ABS lies in incorrect indicators from the sensors installed on the wheels, it is necessary to check them. Often when carrying out repair work, auto mechanics forget to connect the ABS sensor. There are often cases when it is just clogged with mud, and it must be cleaned. Also incorrectly executed wheel installation can lead to problems with indicators that go from the sensor on the wheel to the control unit; The most difficult problem is the malfunction of the ABS control unit itself. If a program fails occurred, you will have to contact the service center. It is worth noting that some modern car models displays information about the problem with the ABS control unit on the onboard computer.

The ABS system is extremely simple in terms of the principle of operation and self-diagnosis. Not so much reasons, because of which she can fail, and most of them the car owner can detect and eliminate themselves.

What to do if an exclamation mark caught fire on the car panel? :: Syl.ru.

What to do if yellow exclamation mark light up on your car panel? This question is often worried about car owners. It is sometimes difficult for it to give an unequivocal answer, because in machines of different brands the same problems can be displayed on the scoreboard with the help of different signs. So, they will have to carefully understand them, so as not to be at some point in hopeless, or rather, in a slower position.

What unites and distinguishes signs on the board of cars

At the very beginning of the article, we will pay attention to the owners of the car, but what kind of stamps it is neither, there are signs that combine the variety of icons on the scoreboard: Green indicators always notify that some kind of system is on and maintained, and yellow or red Warning about problems. But it is worth taking into account and then the anti-lock system (ABS) is installed on your machine or not.

What the work of the indicators in cars with abs and without it

If the machine has a named system, then the test lamp (the indicator icon is also called) is normal, when you are on the ignition and the parking brake is involved, and go out - after starting the engine and when the parking brake is launched. This passes the testing of the system. And if the light bulb goes out, it means that the system works properly. Glowing longer thanked time indicator signal speaks about failures in the operation of the car systems. If the ABS is not installed, then when the ignition is turned on, the icon appears only in the event of problems that we will discuss in more detail below.

So what could be the reason for the appearance of an exclamation mark?

As we have already spoken, exclamation marks on dashboards of different car brands can be lit by several. For example: in the yellow triangle - a failure signal in the work of an electronic stabilization system, or in red - the emergence of a freelance situation, in brackets - a low-pressure sign in tires (it is mostly about the car of American production). And if everything is clearly clear with the last warning symbol, the exclamation mark in a circle, which arose on your dashboard and not disappearing during the trip, may be a signal about several different problems:

Lack of brake fluid; violation of the integrity of the circuit of the indicator; violation of the tightness of the vacuum brake amplifier; Bringing to the working state of the parking brake.

By the way, in the case where the anti-lock system fails, the control lamps and the brake system light up, and ABS!

Do not forget about the information on the scoreboard!

By the way, in any case, signs appearing in the panel, this is also a reason to find out the reason for the warning on the information scoreboard. To figure out more accurately, it is worth opening the section "Machine Information". To do this, enter the menu and, switching up or down, confirm your choice. Thus, you can find out what exactly the sign of danger is reported to you. As already mentioned, in some auto an exclamation mark may indicate not only defects in the brake system, in such cases the fault description is displayed on the display of messages in the dashboard center.

How the indicator lights up when the brake fluid is lacking

So, for a start, assume that the indicator reports on the insufficient level of the brake fluid. If this problem appeared in your car, then an exclamation mark is burning on the scoreboard and while driving. Check if everything is in order and, if necessary, the TZH. True, it should be remembered that later when you have to change the pads, it can rise in a tank and shed. Be careful, try to suck it with something. To do this, there may be a rubber pear.

What if the DM is normal, and the indicator continues to glow?

If the brake fluid is at the maximum level, and the exclamation mark is on, it is worth checking the braking system, even if the pedal is fine. Put the car on the jack and try twisting any wheel. So you are digging, whether the pads are not covered. Experienced drivers advise in such cases to remove the front wheels, after which it is possible to determine the state of the brake pads. If a malfunction is found, they should be replaced.

A warning

Of course, in this case, it is best to find the nearest service center to check the braking system of the car. By the way, along the way to an unscheduled check, you need to be ready for what will have to harm in the pedal in case of the need for braking. And also to the fact that the free course of the mentioned pedal will increase, as well as the braking path of your car. By the way, if the icon is on, along with the ABS indicator, then premature locking rear wheels is possible when braking.

In what other cases the exclamation mark lights up

If the TZh at the normal level, and the brake pads do not cause complaints, and the warning sign of the indicator is on the panel anyway, what can it mean? In this case, it is worth assumed that something happens with the wiring: the system, most likely, began to work on opening. When cutting any wire, leading to the pad sensor, the lamp lights up, signing on their wear. In this case, you, of course, you can close the wires, but then you will have to climb a car every 2000-3000 km to check their condition. So it is better to go to the service.

What can be done yourself

Try to remove the connector from the tank cover, where the brake fluid is located, pull the rubber case from it and, if it is wet from the liquid, blow and wipe it. Check if an exclamation mark went out. Put the connector. If the indicator has come again, then the level sensor is most likely defective. It happens that the brake fluid falls into the middle part of the lid and closes the contacts. To do this, disassemble the lid, clean and dry. Such an operation can be done at home.

If in the car there is a manual brake sensor

If your car is equipped with manual brake sensors, then a similar signal may be a warning of its malfunction. The same effect can also make problems with the rolls of the handbrake. After all, it is enough to inactively move from the fifth or when leaving the nature of "sit down" to the refined cobblestone, so that the cable is obtained by a strong load along with internal damage. For a while he will still work, but in the end the place of damage begins to "shame". And, as a result, even your muscle strength will be enough, so that with the help of a cable, the brakes jamble (when you release it, it cannot return to the previous position, and the car rides on the brakes).

In this case, after an exclamation mark comes around, try to raise the handbrake to the maximum, but do not make great effort. If you feel the backlash (the impression as if the handle is not fixed and simply hangs on the crossbar), then this accurately means problems with cables. By the way, if the warning signal is not lit, and the rear wheels are overheated when moving, then, most likely, the mechanism of the parking brake is faulty.

Airbag Lamp on dashboard

What to do when the security system lamp lights up?

Any modern car is equipped with various security tools.

When such a light bulb, airbag caught fire - clearly indicates that at the moment the pillows do not work. The meaning can not only burn constantly, but also blink, like a check of Endzhina, thereby pointing out the specific error code in the security system.

Thus, the mandatory attribute of the car was the presence of at least one airbag cushion. And when problems with this system, the driver, on the dashboard, signals the airbag lamp. In any machine, you can find the "SRS" marking somewhere in the front of the cabin, which is a reduction from the "Supplementary Restrain System" or how the system of expanded security system sounds in Russian. It consists of a certain number of pillows, as well as elements such as: seat belts; sickness; Tension fixtures; shock sensors; Electronic control system to all this, which is the brain of automotive security.

SRS system, like any other complex car node, can fail due to breakdowns of a certain part or loss of reliability of the relationship between the elements. It happened exactly this if the airbag lights caught fire on the dashboard, the indicator of which differs in different models of cars.

Why does the Airbag indicator on the instrument panel light up?

If the airbag lamp lights up, this means that a failure occurred somewhere, and the problem may concern not only the most pillows, but also of any other element of the side security system.

If there is no breakdown, when the ignition is turned on, the airbag lamp flashes and flashes six times. If everything is fine with the system and it is proper, the indicator comes independently after that until another motor start. If there are problems - it remains to burn. The system starts an independent diagnostics, detects a malfunction code and records it in memory.

After first testing, after a short period of time, the system tests its elements again. If the breakdown was defined erroneously or the signs of malfunction disappeared, the diagnostic module erases the error code recorded earlier, the lamp goes out and the machine operates in normal mode. The exceptions are cases with the detection of critical breakdowns - their codes system stores in long-term memory and does not erase.

Possible malfunctions

If you have SRS on your dashboard, the problem is necessarily present. Modern automakers are very responsible for the organization of the safety of the driver and passengers, so the devices that are responsible for this are considered the most reliable and reliable elements of almost any machine. That is, if AIRBAG is burning, you need not to reflect on a possible problem of security management, but to start looking for a problem, since it is present with the highest share of probability.

If you have a light airbag lamp, it can mean one of the following problems:

Violation of the integrity of any element of the system; stop exchanging signals between system elements; Problems with contacts in the doors, which most often happen after their repair or replacement; It is enough just to forget to connect one connector, and you are already constantly burning SRS; mechanical damage to the impact sensor; Circuit or damage to the wiring between any parts of the security system; fuse malfunctions, problems with the passage of signals in places of compounds; mechanical or software damage to the security control unit; violation of the integrity of the system as a result of installation of signaling elements; The inaccier replacement of the chairs is also the reason why the airbag lamp is burning, since the wires and connections passing there were damaged; Restoring airbags after they are triggered without resetting the memory of the control electronic unit; Excess the resistance value on one of the pillows; Critically low voltage in the onboard power grid; If you have airbag for this reason, it is enough just to replace the battery; excess of the operational period for airbags or sopatrons, which is most often worth up to ten years; Completed tuning amateurs, which can lead to a violation of the integrity of the wiring or sensors; wetting sensors due to car washing; Incorrectly performed battery replacement.

In addition, the airbag lamp can light up due to improper replacement of the steering wheel, since it is necessary to remember both the safety pillow itself, and the elements of the protective system located in the steering or the immediate proximity of it.

Troubleshooting

When SRS is on, you need a strictly verified sequence of actions:

First, the system works itself - checks its performance when the ignition is turned on, when an error is detected, it records its code; Next comes the mechanic - it reads the code and determines the cause of the breakage; The system is checked by specialized diagnostic equipment; Repair operations are performed; The memory of the control unit is updated.

All operations must be performed only with a completely disconnected battery!

ABS light burns - causes a problem and its solution

ABS is the first and common car active security system. In Europe, a mandatory compoundation of ABS issued models has been established at all, so it is not surprising that even the cars related to the budget category are equipped with it. That's just in such cars, it is almost the only one in the versions of the middle and premium categories, the number of such systems volumetric, and many of the additional systems are built on ABC.

The anti-locking system eliminates the complete blocking of the wheels when braking, which increases the efficiency of the brakes and maintains the controllability of the machine by preventing care of the skid. ABS is useful, but at the same time is another component of the car, which includes a number of structural elements and nodes. And the harder the car and more additional parts in it is less reliable.

System Features

The ABS of two parts - electronic and mechanical. "Relax" link in it is electronics. It is sensitive, so even the slightest negative impacts lead to interruptions in the work.

In a car that is equipped with ABS, there is a warning mechanism that signals the termination of work. And it does it by signal lamp on the dashboard.

When the ignition is turned on, this lamp lights up because self-diagnosis occurs. The system checks its performance, and if the violations are not selected, the lamp goes out, indicating that the ABS is in working condition.

But drivers face that the ABS warning lamp lights up while driving, and this can occur only under certain conditions. One signal may not go out at all, the other lamp lights up only when a certain speed is reached. The lit warning lamp enters the monstering of the owners, and the reason for this is simple - ABS works with brakes and system malfunction. They perceive as the appearance of problems with the braking system, which is erroneously.

ABS is an addition to the car brake system that increases its effectiveness. Therefore, even when ABS malfunction, the car saves the ability to slow down, but it is necessary to get used to the operation of the brakes.

The anti-locking system is built so that when a malfunction is detected, it is immediately completely disconnected in order not to impose any effect on the operation of the brakes.

The car enthusiasts arising ABS problem decide: the fuse is responsible for the operation of the system, and postpone troubleshooting to a suitable case. But it will not be possible to do so if a number of security systems are installed on the machine and some of them are built on ABS. In this case, it will not be possible to continue the movement, since the electronics due to malfunction will block the operation of a number of nodes and systems. It is better not to postpone the elimination of the cause of the anti-lock system.

Why did the ABC lamp caught fire?

Video: ABS Light Bulb does not burn braking signals on the instrument panel

As already noted, breakdowns occur in the electronic component, which includes sensors installed on the wheel hubs and control unit. The mechanical component of the problems does not deliver.

The "culprits" of the lighting of the ABS warning lamp:

Fuse; Sensors for determining the rotational speed of the wheels; Specifying elements of the sensors; wiring; Control block.

Because of what the ABS will be sold by checking the listed components to reveal it is not difficult if the car is equipped with an on-board computer with a display that error codes are displayed. This will significantly narrow the circle of searches, because in the code you can find out what a junk sensor.

In a car without an on-board computer display, you will have to look for a scanner and connect it to the diagnostic connector to determine what caused failure.

Note that the definitions of the error code will make it easier to find a search, since the accurate information diagnostics will not give, it will indicate where to look for a fault. Therefore, you can do even without scanning.

We are looking for the cause

Begin troubleshooting follows from the fuse. If this element is braid, the ABS does not work. Note that it is not always necessary to climb into the fuse block, since the behavior of the system itself can give a "tip" relative to the health of the fuse. For example, if the ABS lamp on the instrument panel lights up only under certain conditions, but after turning off the power on the ignition lock and re-start the engine, the problem disappears, then the malfunction is clearly not in the fuse. It should be checked only if the signal lamp burns constantly.

Sensors are located in a place that you will not call well protected. Therefore, the dirt putting on it will easily cause a violation in operation, which is why the system will turn off.

Sensors can simply break during the repair and maintenance of the chassis. Inactive work, the use of impact tools during disassembly is often caused by internal damage to the sensors. Since they are not repaired, then to restore the ABS performance, the damaged element will have to be replaced.

Alarmly disconnect the system can be due to the specifying elements of the sensors. They are installed on the hub, and during operation, too, can be covered with mud, which will violate the functioning of the sensors. The inaccient carrying out of the maintenance of the chassis can also cause damage and destruction of the specifying elements, which will affect the performance of ABS.

More often, the problem occurs due to wiring. The oxidation of the contacts, the mistress or interrupting the wires coming from the sensors - this leads to a violation of the operation of the system and triggering the warning lamp. Sometimes in the process of servicing the chassis, the wiring is disconnected from the sensors, and then forget to connect it back. Therefore, when searching for reason, inspect the wires for damage, their terminals, and only then pay attention to the sensors.

Faults due to all of the above elements of the system are considered easy, since they are easy to eliminate and costs it inexpensively. Worse, if the problem occurs due to the control unit. In this case, you need either a flashing of this element, or replacement.

The anti-locking system fails due to damage to the components and nodes, near which the sensors are worth. The ABS is turned off if the hub bearing is strongly worn. Because of this, the hub is very pitted, which leads to a violation of the operation of the ABS sensors, and this is the cause of an emergency disconnection.

Before the appearance in cars in the 70s of the 20th century, the ABS system was less secure, if you compare them with today's modern cars. Especially this concerned that moment when the driver had to move or wet, or on a snow-covered garbage. In those years, old cars are usually equipped with not very high-quality wheels (tires), not quite reliable rear-wheel drive, as well as the usual and simple brake system without any electronics. But today, as you know friends, everything has changed for the better. Nowadays, most of the drivers are not even thinking about the modern brake systems standing on cars. Today, each of us (drivers) feels behind the wheel of the car confidently and reliably, even when moving or specifically ison. The thing is all next. Most modern machines in our time are equipped (equipped) with front-wheel drive, which gives drivers confidence when finding an auto drive. And moreover, these cars are also equipped with the latest modern electronic security systems that control the adhesion of the car with a road surface, and excellent modern rubber, which demonstrates on a slippery road just some wonders of clutch with such a track. One of the most important systems in any modern car today is the anti-lock brake system (ABS), which significantly reduces the braking path of the machine and prevents the wheel blocking, which can lead to loss of adhesion with the road and, accordingly, further to the drift.

The "ABS" system has become in the automotive industry already with standard equipment, it is actually installed at our time to each modern car manufactured by automotive companies. As we have already already written, this system "ABS" consists of several parts, namely, from the speed sensors, which are set specifically on the wheel wheels, from the electronic control unit of the anti-lock brake system, and also hydraulic valves, which on a specific electronic block signal here -Well regulate in each wheel a certain braking force without resorting to the help of the driver (without his participation).

Wheel sensors "ABS" track the speed of rotation of each vehicle wheel and constantly transmit data to the auto computer. As soon as the system unit "ABS" begins to notice (see) that the wheel ceases to rotate, then it will then activate the valve of the hydraulic brake system and it in turn instantly begins to reduce the brake pressure in this wheel itself. As a result, the pressure of the brake fluid in the wheel is also dropping and the braking force decreases, which contributes to further unlocking the wheel and return the clutch with the road. This process through the computer is repeated several times per second and until the car does not stop or the driver himself will not release the brake pedal.

The control unit "ABS" and a car computer every time the ignition is turned on automatically performs the self-testing of the anti-lock brake system. That is, every time you start the car immediately there is an automatic "ABS" system. In the event that during the self-test, the auto-computer is not enough from sensors, from the ABS control unit and from the brake hydraulic valves, the car lights up the signal lamp with the "ABS" icon. For example, let's say if the car's computer or the same control unit "ABS" did not receive the reverse signal from the brake system hydraulic pump or from the same valve installed on each wheel, then the "ABS error" signal will immediately light up on the tidy (on the panel). In the form of an icon (indicator).

Please note your attention specifically to that, namely, despite the malfunction of the "ABS" system and the appearance on the dashboard of its burning "ABS icon" in the car itself, as a rule, a mechanical brake system continues to work and Without fear, continue moving by car, but without this electronic system in the help of blocking wheels during braking. That is, in other words, we can say that when the "ABS" system crashes, you can safely use your car. True, in this case, it is necessary to be extremely careful when braking on a wet, snow-covered or slippery road, since without this system "ABS" the wheels of your car can be rejected. Therefore, we do not recommend friends in the event of a malfunction of the ABS system to operate your car without appropriate repair for a long time. Thus, all drivers should understand that in case of issuing a "ABS error" auto-computer, it is necessary to establish the cause of this malfunction as soon as possible and eliminate it in the shortest possible time.

Malfunction of the "ABS" system.

And so let's say. In your car, the instrument panel burns the warning lamp or the icon warning of you about problems with the anti-lock brake system. What should I do in this case?

First, first, you must make sure that the icon light indicator indicates the problem with the "ABS system", and not for the malfunction of the entire braking system of the car.

To do this, you must carefully listen to your car when braking and pay your attention to the brake pedal. If during braking you started to hear extraneous noises (whistles, knocks, screenshots, etc. sounds) or the brake pedal in the car became too soft (softer than usual), then your task is a direct road to the technical autocentre, where experts Must carry a thorough diagnosis of the entire brake system of the machine. Please remember that all these signs indicate a serious malfunction of the entire brake system of the car, which can lead you while driving to the accident. Therefore, remember friends if the brakes of your car have become very bad, soft and not quite ordinary, we do not recommend that you leave onto the road of general use with such brakes, as it can be very dangerous. In this case, you need to call the tow truck.

Also, to specifically find out that the light icon-symbol "ABS" of faults caused exactly the anti-lock braking system of the car, you need to also make sure that the car did not hit the brake system, that the brake pedal on the car is still tough, and not Too soft, and more make sure that there is no brake system. To do this, you must first check the level of the brake fluid in the tank, and then only all brake tubes and hoses for the subject of depressurization or cliff.

Among other things, it is necessary to remember that when the ignition is enabled, seeing such a tanned "icon-symbol ABS" on the dashboard, it is not necessary to panic. Maybe this is just the usual error of the electronics of the car. Therefore, in such a situation, it is necessary to turn off the ignition and remove the key from the lock, and then re-enable the ignition and check again, whether the "icon-symbol" icon "appears on the tidy (on the panel). You need to repeat this process several times. It is possible that this is really a computer computer error and after several such inclusions and ignition shutdens This ABS error will simply disappear.

If you still after several attempts to turn on and off ignition, this "ABS" system error does not disappear on the dashboard, that is, it will not disappear, then you have two options:

First; - Go to the car service and spend a thorough computer diagnostics of the entire car. The main feature of the diagnostics of the ABS system is as follows, that is, in the electronic survey of the block "ABS" with the help of special equipment to all sorts of errors in its system.

Using such diagnostics, a specialist will quickly determine the "code" code of errors in the ABS system, which specifically led to the appearance of the ABS icon of the ABS icon on the dashboard.

Also, this very "error code" will give a specific prompt, where it is necessary to seek the cause of the problem of the entire "ABS" system.

The second option needs only those drivers who want to get to this very truth on their own and their own. In order not to use (not apply) expensive diagnostic equipment testing equipment "ABS", you need a service manual to your car (book on repair and operation of your car model), also a simple car tool that is sold in any auto shop and naturally multimeter with high resistance (with high impedance). If you can not find on sale the necessary book on the repair of your car model, please look for it on the Internet "Internet" or download it to your computer or your smartphone.

We pay friends your attention to the following that in some cars you can get direct access to the diagnosis of the same "fault codes", which are stored in the car's computer, and all this without using a special diagnostic scanner. To do this, you need to check each electronic block of your car (including the "ABS" control unit) using an old proven method, namely, using two simple wires that you must connect to the appropriate connectors of the electronic machine systems. For example, you can connect these two wires to check the circuit closer in the same control unit "ABS", for which you need to connect these two wires directly to the control unit "ABS" and closer with a pin or ordinary clip. If, after this procedure, the ABS icon icon error from the dashboard will disappear, then the reason for such an error is in the control unit itself of the anti-lock brake system. Similarly, in the same way, you can connect with a clip or pins and without the use of wires, other specific and necessary contacts.

If dear motorists your car is equipped with a more modern computer, where the error detection diagnoses is carried out only by connecting the scanner to the diagnostic port "OBD II" (on-board diagnostic), then to establish the cause of the ABS icon appearance on the dashboard. It will take only the electronic diagnosis that you can make either in the technical center, either yourself, but already with the help of your boring error scanner to port "OBD II".

Suppose the following that you do not have any error information in the car's computer, which led to the appearance of the ABS symbol icon on the dashboard. Do not rush to carry out computer diagnostics. To begin with, check the "ABS" control unit fuse. After all, a common cause of the "ABS" system malfunction becomes the usual fuse of the anti-lock brake control unit.

And so follow further, you checked the "ABS" control unit fuse that was in working condition. What to do now? And now you must use the multimeter to check the voltage and resistance in all electronic parts of the "ABS" system. To do this, familiarize yourself with the manual and repair of your car namely, with all the relevant control values \u200b\u200bof the voltage and the corresponding resistance in the "ABS" sensors and in the electronic unit "ABS".

True, you must not forget before this check the main harness of the wires that are connected to the control unit "ABS". Carefully inspect the entire harness of wires responsible for the performance of the entire "ABS" system for damage. Also, pull the connector of this wiring harness from the control unit "ABS" and inspectatively all the contacts in the connector, for pollution or oxidation. All contacts with wires in the harness must be clean. If the contacts need cleaning, then with the help of a special aerosol spray to clean electrical contacts and connectors, take and clean the connector from this contamination.

Also, when inspection of the contacts of the "ABS" wiring harness connector, pay attention to corrosion of contacts. Please remember that even microscopic chemicals of oxidation and corrosion can seriously affect the resistance in the electrical circuit of the "ABS" system. On wires, as many know, a small voltage of electricity (millivolts) and even the slightest increase in resistance due to contamination of the connector contacts can lead to improper operation of the entire electronic part of the ABS system, and also cause an error in this system, which leads to Safety on the Dashboard indication "ABS".

If the controller of the "ABS" system looks integer and is in working condition, and the disconnection of the ABS wiring harness connector from the anti-lock brake system does not help you solve the problem of the burning "ABS icon icon" on the dashboard, then it's time to check the speed of rotation speed sensors Wheels that transmit information to the ABS control unit. To do this, it is necessary to initially measure the resistance of these sensors, verifying them with the control values \u200b\u200bspecified in the repair manual of your car.

If it is resistance within acceptable norms, then proceed to the visual inspection of the wheel speed sensors themselves, the wires themselves suitable for them and the inspection (inspection) of the state of each axis of the gear gear (or on each hub), which are installed in the machine on each wheel . As a rule, such sensors related to mechanical sensors were installed on old cars.

Also, today in many modern cars are currently used sensors that need to be powered by electricity. As a rule, "ABS Sensors" based on the "Hall Effect" (inside the sensor, a semiconductor plate is installed), which, when interacting with a magnetic ring on the wheel hub, fix the change in the magnetic field itself and the electron formation rate on the plate inside the ABS sensors.

Unfortunately, not in all cars these "ABS Sensors" and Wires, by which the signal from the sensors is sent to the ABS system control unit, are reliably protected from aggressive external environment. Ultimately, may fail due to damage and getting dirt on them.

In order to check the status of the wheel speed sensors and the ABS wire wires, it is necessary to start, remove the wheels from the machine, namely, lift the car to the jack from the right side and take each wheel.

So you will get free access to sensors and wires.

If, when inspecting the wiring harness of the "ABS" system and wheel speed sensors, you have detected some damage (or the wheel speed sensor is not securely fixed or hangs), you can assume that you have found the reason for the appearance of an error on the dashboard, which and Reported you about the malfunction of the "ABS" system.

But if you examine these wires and "ABS sensors", you did not find any external damage on them, then remove all the "ABS" system speed sensors from the hub (or from the axis) and check their resistance as we have already spoken using a multimeter ( If you did not do it before). The control values \u200b\u200bof the resistance in the rotational speed sensors can be viewed in special books on the repair and operation of your car model.

We also advise all car owners from time to time to inspect the wires of the rotation of the wheels of the "ABS system", do it even if the anti-lock braking machine works properly and the "ABS icon" icon does not light up on the dashboard. The point here is that, all the wires and wheels rotation sensors are located at the bottom of the car and they are constantly susceptible to the aggressive effects of the external environment. Remember friends that the most important enemy for wires and sensors is salt, which is contained in the road reagent, in water and in the snow.

What reasons are the "ABS" indicator on the dashboard, if the sensors and control unit with the Wires "ABS Systems" are required?

If, after testing, you found that all the electronic parts of the ABS system are in good condition, and the "ABS icon" icon on the dashboard is still on, most likely the problem itself is associated with the hydraulic system of the ABS system valves, which Unfortunately, not subject to partial repair.

ABS is a special designed system that stands on a car braking system and controls its work. The main function of the ABS system is the execution by the driver of optimal braking, without car deposit, despite any adverse factors. Therefore, all new cars are equipped with this system, and, with any brake malfunction, they immediately begin to heat the abs on the dashboard. What could be the cause of problems in the brake system to which ABS reacts? Let's deal with this question.

When does the ABS indicator light up?

A good indication of the ABS is triggered on any vehicles during the inclusion of ignition. This is a normal situation that the electronic "brain" of the car performs its diagnosis, demonstrating the car owner that the system is operational. Then, for a few seconds, the indicator should be extinguished. In the event that this does not happen, or the light bulb absorbed suddenly during the ride, it means that there are some problems that require immediate solutions.

However, there are cases when the failure itself also gives the electronics controlling braking, so it is necessary to watch in this direction, when searching for the reason for the indicator on.
Specific reasons because of which the ABS is burning:

1. Breakdown of the ABS sensor. The number of such sensors is determined by the number of car wheels, that is, as a rule, there are four passenger cars, and they all are located near the caliper of the wheels. The breakdown of any of them leads to the lighting of the system indicator.
2. Disturbance of the main unit of the ABS with the system of its sensors. This breakdown happens due to short circuits, as well as bad contacts;
3. Breakdown of the main unit ABS.

Elimination of other causes of ABS light bulb

The elimination of contactping contacts is performed by their alternate check. At the same time, the four plug of the ABS system are directly behind the brake discs of the wheels, next to the system sensors. The fifth contact is located in the windscarette space, it will be easy to find it, oriented to the vacuum brake amplifier.

Repair, in this case, is disconnected and cleaning each of the contacts. After connecting the cleaned contacts, it is necessary to check the operation of the ABS system. If, during the movement, the bulb does not light up, then the cause of the fault is eliminated.

On cars equipped with onboard computers, all errors are not only highlighted on indicators, but also fixed and the computer itself, which displays them in the form of code. To learn about why the ABS is on your car, it will be possible by this code, finding its meaning on the Internet.

So let's summarize. If, while driving on your car, sometimes it is triggered or simply does not turn off the ABS lights, and independently, using the recommendations given, you cannot eliminate this fault, you will definitely contact the car service. Do not wait until the brakes of your car will be denied, while driving along a lively track.
