With electronic stability control (ESC), a driver can prevent his or her vehicle from skidding when turning a corner, braking sharply or executing a sudden maneuver. In order to help steer the vehicle in the right direction, ESC technology automatically activates the brakes.
Passenger and commercial vehicles are already widely equipped with ESC, one of the most important active safety systems. About 80-90% of the cars on European roads are equipped with ESCs.
A driver can actively reduce the impact of an emergency situation by using active safety technology to prevent accidents from happening altogether. Drivers have more control over active systems in dangerous situations. The performance and surroundings of a vehicle are constantly monitored by various safety systems.
Pre-impact active safety systems prevent or mitigate accidents before they occur.
Electronic Stability Control: Quick Facts
- It protects drivers from losing control in critical driving situations by preventing cars from skidding when turning.
- When an ESC detects a loss of control, it adjusts the throttle and brakes to bring the vehicle back on track, based on data from various sensors.
- Dashboard warning lights are triggered by malfunctioning ESC systems. If the light stays on, take the car to a mechanic.
A car’s electronic stability control, or ESC, assists you in steering by keeping you on course. Find out how ESC prevents accidents by helping your vehicle go in the direction you want it to go by reading on.
What Is Electronic Stability Control?
An electronic stability control system assists the driver in maintaining control of the car in critical driving situations by automatically braking individual wheels. Slippery wheels cause a vehicle to lose road traction, causing it to “spin out” or “plop out.” ESC helps prevent this.
A vehicle’s ESC system provides drivers with a great deal of assistance during hard-steering maneuvers. Flipping over is not explicitly prevented by ESC. It helps prevent a car from rolling over because it keeps its tires on the pavement.
In addition to Vehicle Stability Control (VSC), Electronic Stability Program (ESP), Dynamic Stability Control (DSC), and many others, ESC is marketed under several names.
When is Electronic Stability Control Activated?
By monitoring your steering wheel input, the electronic stability control system ensures the car goes where you want it to go.
If the ESC detects that steering control is about to be lost, it will activate.
During emergency evasive swerves, the system makes adjustments when it recognizes that the car isn’t going where the driver is steering.
When attempting to control a vehicle in an emergency, the ESC also comes into play when drivers move their steering wheel too much (known as overcorrecting). Poorly judged turns can lead to understeer or oversteer by well-intentioned drivers. One of the leading causes of single-vehicle crashes is slipping on slippery roads or hydroplaning.
How Does Electronic Stability Control Work?
Each wheel’s brakes are modulated by electronic stability control. The ESC is also activated when the car is started, like other driver aids. A speed sensor on each wheel and steering wheel activity are monitored in the background by the technology.
In case of oversteer or understeer, the ESC system automatically engages when sensors detect the driver is losing control. In order to bring the vehicle back onto its intended course, it applies or eases the brakes on each wheel. When the driver gives too much gas, the ESC applies brakes if the engine power is adjusted to reduce speed.
A rollover can be significantly reduced by using these manipulations. Keeping the car on the road reduces the risk of it being “tripped” by something off the road and flipping.
- With the ESC, the vehicle is gently steered in a particular direction by increasing brake pressure on one side. Front and rear brakes have different effects based on whether they are applied and how much.
- Hard braking or steering is not automatically applied by electronic stability control.
- Skid direction is estimated by the ESC. For the car to return to the driver’s desired direction, the brakes are applied asymmetrically to each wheel.
- By reducing engine power or operating the transmission, the ESC system slows down the vehicle.
Electronic Stability Control vs. Traction Control
Electronic stability control helps maintain your car’s stability and steering in the direction you want. By using sensors and computers within the vehicle, it is possible to determine whether a car’s motion is intended or actual.
Traction control reduces how much a car’s wheels spin in slippery or dangerous conditions, maintaining the car’s grip between the tires and the road. When accelerating up a slippery hill or moving from a stopped position on a slick or unstable surface, this makes it easier to stay connected to the surface.
For stability and traction control systems to work properly, your anti lock braking system must be functioning properly.
How to Operate Electronic Stability Control
The ESC in your car doesn’t require any action on your part. The steering and speed are monitored as soon as the engine is started.
When ESC detects that the driver is losing control, it activates. If a momentary loss of control occurs, the system automatically adjusts the brakes on each wheel to stabilize the vehicle. As soon as your ESC activates and makes adjustments, a warning light will flash on your dashboard. The system will apply brakes and reduce engine power, causing slight jerks and lurches.
A spin-out can occur when a driver makes a sharp and rapid turn. Make sure you drive slowly and take turns carefully when you are driving. It is possible to help in dangerous driving situations by using computerized driver aids, such as ESC. Driving responsibly on slippery roads requires responsible habits, not ESC.
How Do You Turn Off Electronic Stability Control?
An important safety feature of your car is the ESC system, which automatically kicks in to improve the stability of the vehicle. The act of turning it off is dangerous. Normal driving situations should not be driven with the electronic stability control deactivated. While driving with snow chains or in deep snow, sand, or gravel, it may be beneficial to allow more wheel spin. By pressing the “ESC off” button on the dashboard or center console, you can temporarily disable electronic stability control in most vehicles. Press the button again to activate the control once the need for ESC to be off has been satisfied.
Electronic Stability Control Problems
The electronic stability control system generally works well. There are, however, a number of issues that may arise:
- Air or dirt in your brake fluid or worn brake linings can affect the performance of your anti-lock braking system (ABS).
- When tires have poor tread or are in poor condition, ESC can be less effective.
- The ESC light can be triggered by a defective brake light switch. A simple replacement switch can easily solve this problem.
- It is not always possible to determine the intended direction of travel with steering input during high-performance driving. If ESC intervenes in these situations, it can be unwanted.
Cost to Service ESC
There are a number of factors that determine the cost of repairing an ESC system that malfunctions, as with most automotive electronics. One common problem can be solved by replacing a brake light switch. The cost and difficulty of dealing with other issues can be greater. There may be a warranty on the vehicle that covers certain problems.
It is possible to diagnose and repair electronic stability control system issues at most reputable auto repair shops with the right tools. Because of many variables, estimating the cost of correcting problems here is difficult. It is common for faulty wheel speed sensors to be replaced for less than $200. It costs about $250 to replace a steering angle sensor, including labor, depending on the vehicle. ESC problems can sometimes be fixed by software updates or resets.
There can also be differences in labor rates according to the make and model of your vehicle, as well as your region. With Kelley Blue Book’s Fair Price Range tool, you can estimate auto repair costs for common repairs.
Electronic Stability Control Benefits
Steering wheel position sensors are used by ESC systems to determine the steering response of the vehicle by comparing the wheel’s position with the steering response. To help a driver maintain control, the ESC adjusts braking pressure or engine torque if something is not quite right.
There are many benefits associated with an automobile’s ESC system:
- In slippery conditions, prevents vehicle skidding
- Supports emergency maneuvers in critical driving situations
- Assists with driving safety, comfort, and agility
- Maintains overall car control for the driver
What the Electronic Stability Control Light Means
You should take advantage of your car’s electronic stability control. If the ESC malfunctions, it will stop working until the issue is resolved. There are several possible reasons for an illuminated ESC indicator light on the dashboard:
- Out of control. It senses that the vehicle is not in control and activates the electronic stability control to maintain traction and direction.
- Malfunction. A malfunctioning or deactivated ESC system is present. The problem should be addressed by a qualified mechanic as soon as possible.
- Slippery conditions. When driving conditions are slippery, the ESC dashboard light may illuminate. To improve your control, you should slow down.
Is It Safe to Drive With the ESC Light On?
Despite the presence of an electronic stability control light on the dashboard, you can still drive your car. However, drive with extra caution. It is possible that a steady ESC light indicates a malfunctioning safety feature.
As a result, you have a greater chance of oversteering or understeering and spinning out of control when driving without electronic stability control. Keep off the road if it’s wet, reduce your speed, and avoid hard braking. Getting your problem fixed as soon as possible requires you to visit a qualified mechanic at a nearby repair shop.
Things to Keep in Mind
- A system in ready mode has no ESC light on.
- Your vehicle’s ESC interacts directly with its ABS and traction control systems.
- Properly inflated tires are essential for the ESC system to function effectively.
Conclusion
ESCs monitor steering and enhance vehicle safety by monitoring steering. The electronic stability control helps the driver to control their vehicle by reducing their tyres’ skidding. Slippage, faulty sensors, and wiring issues may occur with the ESC system.
The ESC warning light should be resolved as soon as possible whenever it appears. After this service, you’ll feel like your vehicle is on cloud nine.

Frequently Asked Questions
Is There Any Other Name For This Feature?
In addition to the ESC system, there are two other names for it: dynamic stability control (DSC) and vehicle stability control (VSC).
What Is The Primary Function Of ESC?
A primary function of this system is to stabilize the vehicle when the driver loses control of the vehicle, such as when going too fast around a corner or slipping. In hard steering maneuvers, it keeps the car under control.
Is It Safe to Drive With The ESC Light On?
Even if the ESC light appears, you can drive, but it’s not recommended. In an emergency, you can drive slowly if the light is on and getting quick service is impossible.
What Happens When ESC Fails?
The instrument cluster will display a warning light/message if the ESC system fails. If that happens, you can still drive the vehicle, but it is recommended that you have it diagnosed and maintained at the repair center.
Can A Bad ESC Burn Up A Motor?
ESCs can burn motors if they are bad. Calibration, testing, programming, and the very first power-up should always be completed with a current limiter to avoid motors and ESCs burning.
