All modern cars are equipped with ABS sensors, which include an auxiliary brake force control system. This is one of the subtle systems that often fails to budgetary machines. In Europe, for several years of manufacturers, they ordered any serial cars This security system, and the manufacturers of cheap cars explicitly save on high-quality ABS, establishing not too long and practical systems. Sensors of this system are installed on all four wheels, they are powered when a sharp braking with a wheel lock occurs. IN this case The system unlocks the wheel, gives it to check and gradually slows down.
In fact it turns out that cheap ABS not only do not help brake more efficiently, but also lengthen the braking path. There is one more serious problems - After several years of operation, when the car went beyond the warranty service, on many machines without reasons lights up aBS light bulb. First, ride with constantly burning on dashboard The light bulb is inconvenient, and secondly, if a clear impression that something is wrong with the car. Interestingly, not always a burning Light ABS means a problem with an anti-lock system. There may be other malfunctions.
Why can ABS light bulb can light up?
In a normally running car, this indicator shows you that the wheels are unlocking. In this case, everything works fine, the sensors caught the need to include the security system, initiated its work and demonstrated to the driver that a certain help was performed during braking. When you see a burning ABS light bulb during braking, it is better to let go of a little brake pedal and take the control of the machine on yourself. If you have an expensive technological car, you can trust well-thought-out systems and allow ABS + EBD to make their work. In other cases, the light may burn for such reasons:
- sensors clogged, the on-board computer shows that the diagnostic error code should be read;
- the sensors hit the dirt or rust, which caused the erroneous activation of the anti-lock system;
- there is a problem in an electrical on-board system, which is demonstrated by the air of arbitrary light bulbs;
- the hub bearing has fallen, which forces the sensors by mistake to constantly include the anti-lock system;
- the fuses in the block responsible for the ABS system failed and skip directly;
- an error occurred in the computer, which caused the lighting of the ABS light bulb.
Also, sometimes trouble with the generator and other elements of the electrical circuit of the machine, which may pour out the lighting of the lamp of the diagnostic system or signal lamps of any type. For example, on car Volkswagen. The 2000s of production The light bulb of the anti-lock system is lit even in case of error in completely different nodes. because independent diagnosis It is only a partially admissible method of solving the problem, because often under the driver's hand there are no special tools for a good study.
What can be checked independently with a tanned ABS light bulb?
The first thing you can make on your own in such a situation is to go to the sink and ask to wash high quality wheel disks. Often using such an intensive flushing under pressure, it is possible to clear the ABS sensors located near brake discs. On the way to washing, you can perform another simple test. Spoke up to a speed of 80-90 kilometers per hour, close the windows and turn off the music. If in such a trip mode, you hear a lightweight or annoying roe in the wheel area (front or rear), the likely cause of the burning light will fail hub bear. You can do several other actions:
- inspect the fuse block and replace that module that is responsible for the operation of the anti-lock system;
- if you have the opportunity to read the diagnostic code of the error and read about it on the forums;
- ask a question by a specialist, describing your situation, and then try to fix the error yourself;
- independently get to the ABS sensors, raising the car to the jack and removing the wheels, check their purity;
- inspect the electronic unit control under the hood, check the absence of liquids in it and on it;
- the best solution is to go to a hundred and pay for the diagnosis of anti-lock and electrical systems of the machine.
The last step will definitely be the most correct, as you get a clear answer to your questions, you can define the budget of the repair and the availability of serious problems. Only so you can completely get rid of problems with the burning light bulb of the diagnostic system and other unusual ways of the car behavior. Enough just connect computer diagnostic With an advanced program and test the machine for possible errors. Within minutes, you will receive the necessary information and you can do an independent or professional elimination of the problem.
ABS turns on chaotic, the light bulb is blinking or periodically lights up
One of the most complex forms of breakdowns is the constant blink of ABS light bulb. This means that the anti-lock system sensors send incorrect signals to the computer, which, in turn, gives other incorrect commands to systems and car modules. Many prefer in such cases simply turn off the anti-lock system, as unpleasant cases may occur. For example, the inclusion of ABS at a speed of 90 kilometers per hour with light brake can be output running part Machines and contribute to the complete loss of control over control. It is better to act as follows:
- bring the car to the diagnostics in the service, find out the reason for the chaotic equipment of the equipment;
- for domestic machines, equipped with a primitive remedy against blocking, it is better to immediately disable the system;
- complex designs and onboard electronic systems foreign cars will have to reflash for repair;
- on some machines it will be easier to find a problem and eliminate it than to disconnect anti-lock;
- it should be borne in mind that it is not always the reason for the lighting of the ABS light bulb is precisely this system, problems can be different;
- in the process of diagnostics, it is better to check the entire onboard electrical system and equipment.
Having a certain amount for the survey of the machine, you can get the right answers to important questions. Sometimes lightbulb on the panel can grow into a full repair of important units and knots of the car, therefore it will have to spend a lot. But in most cases, this problem is not so expensive. Cost repair work Depends, of course, from the brand and model of the machine, on the price of spare parts. If the ABS sensor is for domestic auto It costs from 600 rubles, the Japanese SUV will drag out to replace one such sensor more than 10,000 rubles. We offer to watch video about the decision such a problem Using computer diagnostics:
Let's sum up
Problems with ABS is in any case too pleasant incidents. It is better to stay away from various problems, try to exploit the car according to the requirements and advice of the manufacturer. But sometimes it turns out to be impossible, therefore it is necessary to have a good service that can help in different situations. By contacting the official service center with this problem, you can become a victim of an overly scrupulous approach to diagnostics and get huge repair costs.
However, sometimes the problem with the ABS sensor and the burning light of this system can be solved independently. Take advantage of the tips described above in publication to understand all the features of this or that method of troubleshooting. Warning that ABS disabling is completely impossible to produce yourself. The on-board computer either simply will not give to the machine, or starts to behave inadequately, issuing new error codes of the diagnostic system every time. Are you faced with the incorrect work of the ABS sensors and the constantly burning light bulb?
Most modern cars equipped with anti-locking system still at the factory, and drivers are already sufficiently used to permanent help ABS when braking. Despite minor disadvantages, the ABS turned out to be one of the most effective systems that allowed not only to cut the braking path, but also to commit emergency braking maneuvering.
Any car without ABS, while trying to slow down on a slippery road and at the same time make a turn / rebuilding, it will be guaranteed to be taken into a skid, which may end very much deploy. Therefore, it is enough to ride a car with the ABS quite a bit to get used to this level of comfort, and in case of the failure of it, most of the car owners turn out to be absolutely not ready. It often happens that the ABS light bulb is burning on the panel, but no action does not occur on the driver's side to correct this situation.
Why the abs light light lights up
The ABS light bulb, located on the dashboard, serves to temporarily inform the driver about the malfunction of this system. So, every time the engine starts, the ABS system passes self-testing, during which the indicator always burns. To determine possible faults, no more than three seconds are required, after which the indicator goes out. If this does not happen, you can be confident that with careless braking on any surface you can forget.
Since the ABS is a rather complicated system, then it is necessary to understand the ABS light bulb, you need to imagine what it consists of. The main element of the three system.
- Electronic block - it is he who makes decisions and manages the entire system.
- The hydraulics unit is responsible for the pressure in the brake system, and at the time of blocking the wheels caused by pressing the brake pedal lowers the pressure in the brake system, allowing the wheel to rotate.
- Sensors, reading the speed of the wheel. They are located on each hub and constantly transmit information to the central unit.
If the ABS is on the instrument panel, help independently understand what cause will help the error code, the alphanumeric designation of which is displayed on the display on-board computer. You can decrypt it by reading the car instruction or searching for information on the Internet.
Tip! If at the time of starting the motor, the ABS icon caught fire, starting the movement is not recommended. Despite the fact that without brakes the car will not remain, the driver will be difficult to quickly get used to the need to slow down in a new way. In addition, the health capacity and some other driving assistance systems depend on the ABS.
ABS icon is burning - Possible causes of malfunction
Despite the sufficient complexity of the system, when the ABS and an exclamation mark is lit after starting the engine, the reasons for this can be relatively few:
In the case when ABS ESP lights tanned, continue or starting the movement is still not recommended. It is worth understanding that if the malfunction is associated with sensors, wiring or battery, it is possible to eliminate them with their own hands, but the fault of the central or hydraulic unit will require interventions of professionals with the appropriate equipment. You can only try to climb into these complex nodes only having the necessary knowledge and experience.
What can be done yourself if ABS light burns
The very first thing to pay attention to, the code caught fire ABS is on the error code that appears on the display of the on-board computer. Alping it, it becomes clear that it was the cause of a malfunction and whether it is possible to try to eliminate it in place. If the problem is in the sensors, before you search for a faulty sensor or the place of damage to the wiring, you can try a couple of minutes to drown the engine and start it again - in some cases the ABS lamp goes out.
If it does not help, you will have to raise the car on the lift or check each sensor, consistently folding all the wheels. Work is not clean, but it is necessary to perform it. It is pre-armed with a multimeter that can operate in an ohmmeter, since the main method of diagnosing sensors is to measure the resistance of each of them. If the testing of the fault sensors does not reveal, it should be carefully examined by all the wires that they connect to the central unit. Isolation should not be disturbed, and all connecting terminals - without signs of oxidation and dirt.
Consequences of faulty abs
In the case when the ABS indicator caught fire at an inexperienced driver, who never ruled the car without an anti-lock system, the consequences may not be pleasant, especially in winter time. The driver will not be easy to stay without the support of this system and, if he is habitually try to fully squeeze the brake pedal on a slippery road, and besides, even a small maneuver, it will easily depart from the road on blocked wheels.
If the abs light lamp is not constantly, but only periodically flashes at a certain time during the movement, it will also negatively affect the safety. The fact is that if during the movement of the ABS is periodically deactivated, then at the time of the operation of the system, the electric pump begins to take part of the brake fluid. If at this moment you press the brake pedal, it will simply fall into the floor - in an inexperienced driver is very easy to get confused in such a situation, especially at high speed. Of course, after a moment, the performance brake system restored, but sometimes these seconds may not be enough for timely stop vehicle. If you have the opportunity, it is still better to turn to a professional to diagnose the entire system - how it is done can be viewed on the video:
The ABS system plays a special role in the work of the entire car, as it is responsible for safety during movement. Many drivers themselves do not know how to use the brake system, not as it should be. As a result, the operation of the ABS system is knocked down, which leads to an accident. Most often drivers are faced with such a problem.
Because of slippery roads, the driver constantly slows down when the car enters. In order to deal with the problem when the ABS light was caught fire and what to do in this case, you must first know how this whole system works.
The essence of the ABS system
The ABS system was designed specifically for drivers so that they see their errors when the brake is sharply pressing. In the ABS system initially, the blocking is not immediately programmed by all four wheels. With sharp braking, the wheels begin in turn to stop, which reduces the likelihood of car drift. As a result, this reduces the speed of the machine, but it should not stumble.
What enters the ABS system
- Wheel sensors that are responsible for their rotation. Each wheel is installed a separate sensor;
- Hydraulic unit;
- The device corresponding to the controlling work of the hydraulic unit itself;
- ABS dashboard ,.
The main causes of ABS system malfunction
If the ABS lights caught fire on the dashboard on the dashboard, this indicates the emergence of problems in the system. The driver needs to contact the maintenance service to find out the cause of this warning signal. When the system works fine, the light begins to burn during the installation of the engine, and after a few seconds it swings. This suggests that the system is proper, and it is in an active condition. There are such cases when the light bulbs burns, but the car does not start.
In this case, there are many reasons as:
- The problem is the connecting cables;
- ABS system control unit is not in charge;
- No connection with one of the sensors, which is fixed on the wheels;
- The sensor on one of the wheel or sensors on all wheels failed.
As for the cliff of the wire, it can happen during the movement of the car. During vibrations, when moving through poor roads, cables are beginning to weaken and at some point are shredded or completely broken. The driver will be able to solve the problem of this character on his own, not paying for help from professional professionals.
If the ABS sensor light is caught fire due to the failure of the sensors, then this may be the wines of the garbage that is clogged when driving. Such a problem driver will not be able to solve own forces. It is required to take the car to the service station. Often, the reason not to work the sensors is associated with the incompetence of the master on a hundred. During the repair of the wheels, the sensors are constantly disconnected. Only after installing the masters them back, they forget to connect to the wheels. Incorrect wheel installation also leads to the fact that the ABS light bulb lights up.
With the ABS system you need to be extremely neat, because it can be broken quickly, and it will take a lot of effort, time and cash costs for their fix. If the ABS system light lights up due to a broken control unit, it is impossible to find out on its own. Save the ABS system only the on-board computer, which gives an error code. This code must be properly decrypted, because it is the cause of the system failure.
In the case of periodic power on and off, ABS light bulb should be known that there is a problem with contacts. The connection between the contacts is weak and therefore it is necessary to inspect the wires. Independently reveal the cause of the constantly burning of the indicator is much heavier.
Self disconnection of the light bulb
Sometimes the functioning of the ABS system is knocked down and in this case can not be asked for help in the technical service. For this there is an easy way. It is required to accelerate on a flat section of the road with an increased rate, and after dramatically slow down. Sometimes such a procedure helps to restore a knocked system and a light bulb ceases to light up.
If it did not help, only experts can come to the aid, which distribute the system on a special computer and make the exact conclusion why the ABS light lights up. It is impossible to regret the money for such a service, since the safety of life is not only the driver, but also passengers who can be in the car depends on this.
In order to exclude the fact of mistakes in braking, because many drivers have no idea how to brake on the car correctly, was created aBS system. It allows you to effectively, without leaving even in ice. Modern motorists are already so accustomed to this system that put them behind the wheel of a car that is not equipped with such an option, there are no problems. Therefore, for many is a big tragedy, if one day light bulb caught fire.
Indication of the normal system operation mode
On all cars on which the system is installed, the ABS indicator lights up when the ignition is turned on. This is a kind of system verification and demonstration to the driver that the system is active. Then, after a few seconds, the bulb should be ground. If this did not happen, or if during the movement, ABS light bulbs suddenly tanned, then with obviously there are problems, to solve that necessary in the near future.
Therefore, answering the question why the ABS light burns? - We give advice - look for a problem in the brake system or in electronics, which carries out help when braking.
The most common reasons why ABS light burns
- The problem that occurs very often is a malfunction of one of the ABS. Near the caliper of each wheel is installed ABS sensor. And it is worth out of order at least one of them, the system will immediately inform you about it, highlighting the ABS symbol on the dashboard.
- A similar problem is an ABS block coupling with sensors. It may be a closure in contact wires, problems with the contact itself.
- Faults associated with the control unit itself. Error in his work, or failure.
What to do with this problem?
Perhaps this section of our article you expect the most. Well, let's try to give you some useful tips.
As noted, the problem may wage in unreliable contact. To install it, you need to check all connections. 4 contact plug is available for each wheel, i.e. Directly near the sensor itself, and 5 contact - in the subcontrol space, find it will not be a problem, oriented on the VUT.
Dispatternize each contact, clean it from dirt if necessary, then connect again. If it did not help, go further. If on-board computer is installed on your car, you can find an error in the operation of the system using it. True, the computer will give you only a kind of code. By this code, you can find information about the fault on the Internet. If there is no side computer, then nothing can be done.
Many owners of Chevrolet Lacetti have come across that the dashboard lights up control lamp The ABS sensors and at the same time it does not exhaust. What are the reasons for this phenomenon, and how to determine and eliminate a malfunction.
ABS icon.
The control lamp ABS lights up when faults occurs in the brake system or electrical parts of the ABS .
But it is worth highlight the most common causes of this phenomenon:
- ABS sensors.
- Wiring.
- Block abs.
- Brake pads.
- Liquid level and enforcement.
- Brain.
Elimination methods
Panel instruments of a waged car without errors.
After the main reasons for the ignition of the control lamp of the ABS on Chevrolet Lacetti are defined, car enthusiasts are trying to solve this task on their own. In this part of the article consider possible methods eliminating the problem without circulation in the car service where repair will cost quite expensive .
ABS control lamp caught fire on the dashboard.
ABS sensors
The ignition of the ABS lamp on the dashboard indicates primarily that one or more sensors do not give a signal. Thus, there are two options - why the meters refused.
ABS sensor on wheels.
The first - the exit of the system itself directly the sensor itself . Therefore, it is necessary to get to the wire pad, which connects the sensor circuit with the main network. Then disconnect the wires and check the performance of the meter using a multimeter. Such an operation must be made with all ABS sensors, which are installed on the car.
Preparation for dismantling the ABS sensor and its inspection.
The second is the oxidation of the connectors in the wire block . It can happen after driving in the snow or during the rain. To resolve the problem, you need to disconnect the block and clean the contact group. Then, it is recommended to protect the connection with special Tools, Type copper paste.
Wiring
The appearance of the ABS lamp signals a malfunction in the system, and the second place, where it is recommended to seek a fault is the ABS wiring.
So, the wire break, or damage it can lead to the emergence of such an effect. To troubleshoot a malfunction, you will have to call the entire wiring tester and replace the damaged item.
As practice shows, most motorists produce stripping of the damaged area, fastening the wires and their insulation. It is recommended to perform not just twisting of the wiring, but their soldering, to avoid corrosion damage, voltage drops and subsequent breaks. Isolation is better not to be carried out with a tape, but a thermal tube. This will save from moisture from entering repair plot, and accordingly prevent corrosion.
Block ABS
During operation, especially if the car is more than 7 years old, it may happen that aBS block can exit . Definitions of the malfunction of the element are a rather complicated process that is not at the power not every motorist. Since it is necessary to possess certain knowledge in the automotive electrician.
The location of the ABS block by car.
On the replacement of the ABS block and no longer mention, since the incorrect connection of the new element can be carried out to the failure of it, so such procedures are recommended to trust professionals. Therefore, who is not confident in their abilities, it is recommended to contact a car service with a good electrician.
Brake pads
Such pads must force the ABS alert constantly!
Repeated ABS signaling device lights up when wear brake shoes. So, it is worth checking the states of these important elements car. To do this, you will have to remove all 4 wheels and check each block separately, since the sensor could work on any of them.
Brake fluid level and enforcement
The location of the brake tank under the hood.
If the previous options have been checked and the faults are not detected, then it is worth looking into podcast space and check the level of brake fluid in the system. If there is no in the brake tank brake fluid, I will have to drink a little, because we can not do with the usual plot and most likely the system is delivered.
The process of pumping brakes.
To eliminate malfunction, it is necessary to pour fluid to pump all four wheels to drive out the air from the system. But, the brake system pumping will not be enough and it is necessary to reset the error that originated in the electronic control unit.
Brain
The location of the ECU.
Another place where the malfunction can be a fault remains an electronic unit of the vehicle, or in common - "brains".
As it was clarified, the lighting of the ABS control lamp is, is the "disease" of all Chevrolet Lacetti. In most cases, it lies in the program part. So, to eliminate the fault, you must connect to the computer and drop errors.
Connect under the diagnostic line.
If this option does not help, then you should reflash the control unit. As practice shows, it is to be treated not only the problem with the ABS control lamp, but also other frequent malfunctions.
conclusions
Determine why the ABS control lamp caught fire on Chevrolet Lacetti can independently, without contacting the car service. For the process, a little constructive knowledge of the vehicle and time will be required. Well, if there is no first factor, then the straight road in the car service.
