How to turn on the traction control system on the Lada Vesta. The system of exchange rate stability on the Lada Vesta. How to disable traction control on Lada Vesta
Modern Western models have a complex electronic assistants driver may include more than a dozen or two different systems. B-class budget employees are not yet entitled to such luxury by status, but in this part Vesta is ready to give odds to competitors. In addition to the usual set of ABS and EBD, the VAZ novelty is already in basic configuration Equipped with Electronic Stability Control (ESC). Over the winter, I managed to study her behavior enough to give her settings the highest mark.
Firstly, it gives plenty of slip in first gear, allowing you to overcome a difficult section of the yard or an uncleared parking lot. The traction control system in this case is in no hurry to intervene - and it does the right thing. Similarly, it behaves with an overly frisky start from a traffic light on slippery asphalt. This is also to my liking: there is no hysterical help from electronics in situations where it is not required at all.
I note that during the past snowy winter, the stabilization system never worked unexpectedly for me. I'll write it off as good Winter tires and right choice speed. But in safe places I experimented with it to my heart's content.
Do you think ESC should be made mandatory for inexpensive models? Is there any real benefit from it, in your opinion, or is it just another way to rip off more money from the buyer?
Vehicle equipment active systems safety is one of the most important factors in evaluating a complete set. With the development of the automotive industry, the list of these systems is supplemented with new ones, and existing devices are being improved. One of them is ESP - the vehicle's directional stability system in motion, which received this abbreviation, the most common in Europe, from the German definition of Elektronisches Stabilitatsprogramm, since concerns were the first to equip their cars with it 20 years ago mercedes benz and BMW.
Depending on the car manufacturer, this device may be designated differently - ESC, DSC, DTSC, VSA, VSC, VDC, but the essence of its work does not change from this - automatic correction of the car's course in conditions of potential skidding:
- neutralization sharp jerks steering wheel when skidding;
- impact distribution brake system individually for each wheel;
- adjusting engine speed to provide the necessary degree of control of the course of the car;
- control of angular velocity and lateral acceleration to fix the start of a skid.
The importance of each of these ESP functions in ensuring the safety of machine operation is difficult to overestimate, so new models of their cars, including Lada XRay even the basic configuration, AvtoVAZ also equips this system.
The presence of the ESP module in the basic configuration is an absolute advantage, but after the start of sales of the Lada XRay, a circumstance incompatible with the status of a “crossover” was revealed - a car with a clearance of 190 mm gets stuck in liquid mud and light snowdrifts, cannot accelerate on a slippery surface or does not walk on it on the rise. This is especially evident in situations where the tires get stuck in sand or snow, and the stabilization system slows down the spinning wheel and at the same time reduces the engine speed, making it impossible for the driver to “rev up” and leave the problem area.
The merits of each individual ESP function in ensuring safety in a critical skid situation turned into a problem with their simultaneous operation in light off-road conditions, exacerbated by the adjustment of the electronics of the system of the first batches of the crossover to asphalt. The situation was aggravated by the lack of manual shutdown of the stabilization module.
To date, AvtoVAZ has solved this problem - since the end of September 2016, the ESP disable button has been installed on the Lada XRay, and the system, in addition, is set to different types coatings and allows moderate slippage - upon reaching a speed of 50 km / h, the stabilization of course stability will automatically turn on.
But for many owners who have purchased Lada XRay without the option to manually turn off the ESP, the problem remains relevant. Consider ways to solve it - how to turn off the exchange rate stability system on your own, urgently or for a long time.
Emergency shutdown of ESP
Once in a situation where the stability control system is clearly a hindrance on relative off-road conditions, it is easiest to turn it off by removing the corresponding fuse from the socket.
Before removing the fuse, turn off the engine and turn off the ignition.
There are several fuses in the ESP system (F62 - 50 A, F64 - 5 A and F65 - 25 A), the removal of which will disable the ESP, but since they are also responsible for other systems, it is necessary to remove the F62 fuse responsible for ESP, ABS and indication of the parking brake.
After removing the fuse, the box cover is replaced, the hood is closed, and you can continue on your way. After starting the engine, the instrument panel in the cabin will display three burning icons - ABS (not working), ESP (not working) and the parking brake (supposedly activated).
When the car is moving, the ABS and ESP systems really don’t work, but it’s not a fact that a switchable module is a panacea for solving the problem of off-road driving on Lada.
After overcoming the problem area, the engine is turned off, the fuse is installed in its regular place, the electronics on the instrument panel after that does not give any errors in the operation of the systems.
Installation of a fixed shutdown button
This operation is simple and does not require a high level of professionalism from the performer. The purpose of the action is to install a switch in the cabin to break the power supply to the fuse mentioned above. On the instrument panel at the bottom left, between the mirror position control and the headlight range control, there is a socket with a plug, quite suitable for installing a button (according to the characteristics, it fits under the number 251450002R).
The shield assembly is removed from the panel niche, and the plug is removed from the socket. Through the socket, a break in the power wire of the F62 fuse is output to the passenger compartment, the ends of which are connected to the button. The button is fixed in the socket, and the shield is installed in place in the panel niche. When ESP is disabled on dashboard three indicators will also light up - ABS, ESP and parking brake.
Regardless of how the ESP was turned off, after passing through the problem area, for safety reasons, it must be turned on.
In addition, when ESP is disabled, one should take into account the possibility of the presence of impenetrable sections on the road with high-quality coverage, the entrance to which is accompanied by an unexpected strong jerk.
Conclusion
The expediency of installing the ESP disable button on the Lada XRay depends on the operating conditions of the car and the experience of driving specific sections, which determines the effectiveness of disabling the stability system. Disabling the ESP, performed on the Lada XRay not using the standard switch, has another, dangerous side - the absence automatic start ESP and the danger of skidding in a situation where the work of the ESP is vital. Therefore, one should carefully weigh the commensurability of some difficulties when driving relative off-road with ESP turned on and the unpredictable decrease in the safety of operating a car without this system, which was forgotten to be turned on after this off-road.
The Lada Vesta car is equipped with all the most necessary systems that contribute to comfortable driving. All of the systems listed below are present in absolutely all vehicle trim levels, which makes it a very attractive figure in the car market.ABS or anti-lock braking system- in the event of emergency, and sometimes regular braking, it prevents the complete blocking of the car's wheels, thanks to this system, the braking distance of the car is reduced, and during braking it becomes possible to drive the car due to the fact that the wheels are not blocked. During the operation of this system, you will surely hear a characteristic "crack" and a slight beating of the brake pedal.
EBD or brake force distribution- correctly distributes the braking forces of the front and rear axle vehicle, the system is activated if the ABS operation, denoted by dashboard in the form of a red signaling device - "Brake failure".
BA or brake assist- this function reads how quickly you pressed the brake pedal, from the received data the system recognizes whether it was normal braking or emergency. When emergency braking the system will increase the pressure in the brake actuator to a certain level and will hold it as long as the brake pedal is depressed.
HHC or Roll Prevention on Hill Start- when the vehicle is stopped on an incline of four percent or more, the HHC system is activated to help the vehicle start moving further, for the HHC to work properly, depress the brake pedal with sufficient force to keep the vehicle in place after shifting into gear, releasing the brake pedal and depressing the accelerator pedal, the system will hold the vehicle in place until it starts to move, but no more than two seconds. The system will automatically deactivate if the vehicle is parked parking brake or the driver's door of the car is open.
ESC and TC - or stability control and traction control - these two car functions work in pairs and are activated automatically when the car engine is turned on. ESC is responsible for the reliable stability of the car on the road, the system reads the speed of rotation of all wheels, and if one or more of them start to rotate faster, the system slows down their rotation, in more serious situations, the system slows down the engine speed, due to which it returns the controllability of the car. TC performs the same functions as ESC only when starting the vehicle, which reduces excessive wheel spin of the vehicle.

Photo "b"The latest sedan produced by AvtoVAZ really deserves special attention. Serial cars Lada Vesta actively joined the general flow of participants traffic. Every day more and more information comes from people who are directly related to the operation of this car.
Manufacturers have supplied Vesta with many innovations that were not previously installed on domestic Frets. Now, electronic systems security is on LADA cars Vesta even in the basic configuration. How effective and useful are they?
The tests carried out in different situations.
How ESP and ABS affect the stability of LADA Vesta on an icy surface
Lada Vesta continues to be tested in the winter season. This time, a sports ice track with a length of 700 m was chosen as a test site. The purpose of the test is to test Lada Vesta's electronic motion stabilization systems in various situations. As expected, the car is dressed in Nokian winter studded tires.
The first test was carried out with the ESP and ABS systems disabled. To do this, it is necessary to completely de-energize them, that is, remove the fuse. Otherwise, even when the button for deactivating the stability control system is pressed, the computer will turn it on on its own when the speed reaches 50 km.
The sedan briskly moves off from the start. The spikes on the wheels make themselves felt. When entering a turn, the car blows away, but not much. The drive wheels clearly control the road, and the rear begins to demolish. Experienced driver can easily cope with such a situation by adding gas, on which there are no restrictions. Even on the ice, Vesta behaves predictably. Once again it should be noted excellent handling. The car adequately responds to every movement of the steering wheel, smoothly enters into turns and behaves well when moving in an arc.
In the second case, all electronics are connected. From the start, it is clear that the car does not lose much of its dynamism. Again, I would like to note the presence of good studded tires. ESP and ABS systems do not immediately respond to changing situations. Troubles can begin only after the complete demolition of the car. In this case, Vesta rushing sideways is no longer subject to electronics. At the same time, it is more difficult for the driver to cope with the situation, because the gas is under the control of the computer and pressing hard does not bring results.
Conclusion
Comparing the results, it can be noted that with the driving assistance systems turned off, the car passed the track faster by as much as 8 seconds. The slower run with ESP and ABS active is due to the evaluative actions of the electronics. However, it significantly relieves the driver's stress when moving the frets on ice. The choice of riding with or without the electronics turned on depends solely on the experience and driving style of the driver.
In addition to ice and snow, winter can bring other conditions in which the electronics installed on the car can pull out of a practically hopeless situation.
LADA Vesta in a ditch: operation of the stabilization system
On the winter road a situation may occur when the car is forced to snuggle up to the side of the track. At the same time, cases of slipping into a ditch are not uncommon. The next test drive of Lada Vesta showed the advantages of exchange rate stabilization and traction control systems in difficult conditions. At the same time, a comparison was clearly shown without ESP and with ESP.
Sedan was given a difficult task. The car practically hung between the edges of the ditch on two wheels. Usually, such a situation requires mandatory outside help. But the electronics did a great job. Evenly distributing the fuel supply, she easily allowed not only to level Vesta. The sedan, like a crossover, easily climbed the opposite slope of the ditch and also just returned to the main road.
In the second case, in a similar situation, ESP was disabled. No efforts and peregazovki failed to move the car. The driving wheels only melted ice and snow in vain. In this position, without outside interference, it is almost impossible to leave the ditch.
Conclusion
The system of electronic motion stabilization and traction control Lada Vesta proves its advantages both on flat surfaces and off-road. It is useful not only for beginners, but also for experienced drivers who believe that they themselves are able to solve all issues. Indeed, in the presence of ESP, they simply will not arise.
Traction control and LADA Vesta on the rise
Sedan Lada Vesta is designed for urban conditions. But in any case, he will have to leave the confines of megacities at least sometimes. Potholes, potholes and steep hills may occur along the way.
The next test drive of Lada Vesta took place on a cross-country track, where it was compared how best to overcome the rise - with or without electronics.
Four test options were selected. In the first two cases, all driver assistance systems were turned on. With a smooth start, the car did not reach half the hill. The engine did not have time to gain momentum and refused to pull the car further. Overclocking gave better results. The car went up a meter further and stopped.
Disabling traction control changed things a bit. A smooth start, as in the first case, did not show any special results. Having reached a certain level, Vesta began to rake the ground in vain. Acceleration greatly increased the distance traveled.
Conclusion
Such situations are not uncommon. As in most cases, the way out depends on the experience of the driver, because electronics are not yet able to solve all problems.
Speed requires a reliable braking system. After all, blocked wheels often cause a strong skid, which can lead to trouble. How electronics can help with hard pressing on the brake pedal?
How effective is the ABS system LADA Vesta
The next test drive provides information on how disabling ABS Lada Vesta can affect braking performance car.
The car was tested on loose snow and clear ice. The included electronic systems make it easy to drive. Snow and ice cease to be obstacles even for novice motorists.
The test showed the following results. ABS, together with ESP, effectively coped with its task. The car made smooth braking even with the steering wheel released. There was no mention of any drift. Things went quite differently after the disabled brake force distribution system. This time, the braking distance became shorter, but the procedure required considerable effort on the part of the driver. Even with great experience, the car went into a skid.
conclusions
Despite the shorter braking distance, disabling ABS on the Lada Vesta is not recommended. The new systems work differently than the earlier versions when they had no control when disabled. rear axle. The machine could somehow remain in a stable position. In the current version, with ABS off, the cylinder evenly distributes braking force between all four wheels. With increased pressure on the brake pedal, all wheels are blocked and the car becomes completely uncontrollable. The drift is secured.
Lada Vesta has quite decent dynamic characteristics. But, they describe the state of affairs on a good, dry road surface. What will happen to the acceleration if the car is on a snowy or icy road?
LADA Vesta electronics being tested in Lapland
Another test drive Lada Vesta in winter conditions took place in Finland. For this, a test site has been set aside. Nokian Tires, where the Russian sedan tests tires.
The subject of the test was again the system of exchange rate stability, around which there are constant disputes. Experienced drivers believe that ESP and ABS are only for beginners and are an expensive toy.
The road surface was ice. The systems had to show their effectiveness with a sharp and smooth start. In the first case, the car took more time to accelerate. With a sharp pressure on the gas, the car quickly starts to gain momentum, the wheels slip. Only moments later, the electronics kick in and acceleration becomes controlled. Smoothly depressing the accelerator pedal allows the ESP system to distribute the grip of the wheels with the road in a timely manner and evenly accelerate the car.
A similar situation with the “traction control” turned off showed that with a sharp start, a strong slip occurs, leading to a loss of time. Smooth start showed best results. An experienced driver feels the behavior of the car well and distributes the pressure himself.
On loose snow, the results with the ESP on, with a smooth and hard start, were almost the same. Turning off the electronics allowed for the most efficient acceleration, and again, smooth pedaling greatly reduced the speed gain.
Conclusion
The results obtained again came down to the fact that the main advantage of control is the skill of the driver. However, even for experienced motorists, over time it will become clear that ESP and ABS can make driving Lada Vesta much easier.
Only lazy people do not talk about safety issues in the process of driving a car. Manufacturers are ready to resort to any tricks to attract buyers. Safety is one of the most important arguments, among other arguments, in trying to draw attention to a particular car. The traction control system rightfully takes its place among other means of motion control, providing optimal conditions machine control.
The principle of operation of the traction control system
To understand what it is and how it works, you need to remember that the movement of the car is due to the adhesion of its wheels to the road surface. And if the adhesion to the road is insufficient, for example, if it is slippery or wet, then slippage occurs, due to which acceleration dynamics are lost, controllability deteriorates and the likelihood of the car skidding increases. Yes, and tire wear in this case increases significantly.
The principle underlying the work traction control system, – wheel speed control. If during acceleration it starts to rotate too quickly, then the controls, depending primarily on the speed, take corrective action. This can manifest itself both in its braking and in reducing the transmitted torque.
Anti-slip system, how it works in real conditions
- the presence on the car of such devices as ABS and ESP;
- the presence of the so-called electronic pedal gas”, i.e. lack of direct connection between the gas pedal and the throttle.
In fact, this is the opposite of ABS, if it removes braking from the wheel to ensure its adhesion to the road, then the traction control system slows down a wheel that is too “nimble” for the same purpose. Yes, and in their work they use the readings of the same sensors. 
The traction control system is called differently - ASR or TRC, TCS (traction control system), and these abbreviations do not exhaust all the possible designations that the traction control system receives from different manufacturers. Nevertheless, despite the different names, the principle by which any of them works is almost the same.
The sensors used by all these systems - ABS, ESP, TRS, ASR - are the same. In its simplest form, for example, the ASR traction control system receives signals from sensors, by which it determines:
- wheel speed (angular);
- their position (the movement is going straight or a turn is being made);
- the degree of wheel slip, based on the calculated difference in their angular speeds.
Based on the data obtained, depending on the speed, the traction control system can:
- through the system solenoid valves change the pressure in the braking system by reducing the wheel speed;
- issue a signal to the engine control controller to reduce torque;
- change the amount of torque supplied to the slipping wheel through a partial differential lock;
- take several marked actions at the same time.
What capabilities a particular traction control system TRC, TCS, ASR and others similar in purpose has is determined primarily by the design of the car, as well as software. However, despite the existing differences in implementation, the traction control system, regardless of the type - whether it is TRC or ASR, when it works, provides confident acceleration of the car and reliable adhesion of rubber to the road surface.
ESP traction control
The traction control system such as ESP deserves special attention. It is responsible for the directional stability of the car, preventing it from side sliding, skidding and rotation. If ABS works when braking, TRS and ASR when accelerating, then ESP works when cornering and maneuvering. In fact, these elements of controlling the current behavior of the machine create, if not completely safe, then as close as possible to this condition.
During operation, ESP compares the direction of movement set by the driver with the real one. All control is carried out by signals from sensors dozens of times per second, almost the car is constantly under the control of electronics. If there is a discrepancy between the specified and the actual direction of movement, i.e. slipping or skidding has begun, ESP takes the necessary measures to eliminate it in a split second.
To do this, the traction control system reduces the speed of the car and slows down the necessary wheels, returning the car to a given direction of movement.
Whether it is TCS or any other traction control system, they ensure the safety of the car and are used by their manufacturers more and more widely in cars of various classes. This approach avoids critical situations when managing vehicle many, including experienced drivers.
