What Does ESC Off Mean On My Dashboard?

ESC Off means that the electronic stability control (ESC) has been turned off in your car. The system prevents the car from spinning out of control when negotiating corners. It applies brakes to each wheel individually to prevent unnecessary sliding.

The ESC OFF light on your dashboard means that the feature has been turned off. Sometimes, this happens by accident. It can also be a sign that something is wrong with the ESC system. The car’s computer may have detected an error.

What does ESC do in a car? How does it work?

The electronic stability control on your car monitors the speed at which each wheel is moving using sensors placed inside the wheels. A control unit monitors the steering wheel angle and the rotation of the car’s vertical axis.

This information is used to determine the direction the car is traveling and ensure that it corresponds to the steering wheel’s position. If the control unit detects a mismatch, it knows that the car is moving in a different direction from the steering applied.

It will, therefore, initiate braking in the appropriate wheel(s) to prevent the car from spinning out of control or plowing out. This comes to effect with the help of the anti-lock braking system (ABS) and traction control system (TCS). It prevents collisions and accidents that would otherwise occur without the feature.

The electronic stability control works very quickly and you may not even notice it when in action. Also, it eliminates the need to correct your steering when taking sharp corners at high speed. One thing to note, however, is that it will not steer your car automatically nor prevent it from rolling over.

What does it mean when the ESC light comes on?

The ESC light could mean a few things:

  1. The electronic stability control feature on your car is turned off
  2. There’s an error in the electronic stability control system
  3. Your car is trying to maintain traction control while negotiating a corner
  4. The ESC system is malfunctioning

What cars have ESC feature in them?

Electronic stability control (ESC) is a mandatory feature in all cars made after September 1, 2011. It was first introduced in the 1995 Mercedes-Benz S600. Since then, it goes under different names, including DSP and ESP.

The most common cars that experience problems with the “ESC Off” message include Jeep, Fiat 500, Kia Sorento, Kia Sportage, Kia Sedona, Hyundai Tucson, Hyundai Sonata, and Hyundai Santa Fe. The message sometimes takes the form of a slip indicator light in most cars.

How do you fix ESC light?

1.    Switch ESC on

Start by confirming if the ESC is switched off. Some cars have a button that can be used to turn the feature on and off. Turn it on and check if the light will go off.

2.    Replace wheel speed sensor

The electronic stability control may be failing due to a bad wheel speed sensor(s). Bad sensors can give an erratic reading or fail to monitor the wheel speed at all.

Check the wheel sensors using an OBD-II scanner to confirm that they are working as they should. Monitor the speed reading for each sensor while driving to ensure that none is giving a bad reading.

3.    Replace steering angle sensor

The steering angle sensor monitors the position of the steering wheel in tandem with the direction the vehicle is going. It’s also part of the car’s electronic stability control.

If the sensor goes bad, the ESC will not be able to detect errors and know what’s happening. It’s important to check the steering angle sensor and confirm that it’s working as it should.

4.    Check the wiring

Wiring and electrical problems can cause the ESC to fail. To fix the ESC malfunction, you’ll need to confirm that power is flowing from the battery and that there’s communication between the sensors and the control unit. Check for any exposed or damaged wires.

5.    Check ABS and TCS

Your car’s electronic stability control works together with the anti-lock braking system (ABS) and traction control system (TCS) to maintain control of your car. If either of these systems fails, the ESC will not work. These systems must also be diagnosed for problems if the ESC light is on.

Is it safe to drive with the ESC light on?

You can drive while the ESC light is on. However, it’s good to note that the feature may not work when maneuvering corners at high speed. It may also not provide the additional support your car needs to stay stable and move in the right direction during such moments.

You’ll have to slow down to help maintain control over your car. Take turns carefully and slowly and avoid speeding while the ESC light is on. This is especially if you’re driving on ice or slippery roads. The light will stay on until it’s fixed.

Does ESC improve traction?

No. ESC does not improve road traction. It helps to keep the car under control and stable when making sharp corners at high speed. It’s a revolutionary feature that keeps the car moving in the same direction in case it loses control.

Without it, car owners would have to correct oversteering or understeering manually by correcting the steering wheel’s position. Oversteering occurs when a driver tries to negotiate a corner at a speed too extreme for the vehicle to make it.

On the other hand, understeering occurs when the front wheels lose control due to low friction. This happens when you’re driving on ice, slippery roads, or on a surface that has less grip.

When should you turn off ESC?

You should not turn off ESC in your car. This is because it disables the stability control feature that keeps your car stable when driving. Only disable the ESC in your car if you’re seasoned professional driver.

Some racecar drivers turn it off so that they can have full control of the amount of power going to the wheels. This allows them to spin the wheels to their liking and even create burnouts behind them.

For most people, it’s not necessary to turn off electronic stability control. It’s best to leave it to racetrack and performance car enthusiasts with vast experience.

Does turning off ESC make a car faster?

Turning off ESC means that the car will not apply brakes to individual wheels when negotiating a sharp corner at high speed.

The car may, therefore, feel a bit faster than it usually does. This is because the braking effect usually slows it down to maintain control and stability.

Final Thoughts

Despite all the benefits that come with the electronic stability control, it’s important to note that the feature does not substitute for safe driving. I hope this article helped you figure out what the ESC Off means on your car. Remember to observe all traffic rules and practice safe driving. Stay tuned for more guides.
