Our step-by-step guide is here to arm you with the knowledge you need to conquer this dashboard demon. In just nine simple steps, you can turn off that pesky light and get back to enjoying your ride safely and confidently.

How to Reset ESP Bas Light

To reset the ESP Bas Light, first of all, you need to start your vehicle and turn the steering wheel as far right and left as possible 2-3 times, return the wheels to the center position, and finally stop the engine.

 

1. Understanding the ESP BAS Light Function

The ESP BAS light is integral to your vehicle’s Electronic Stability Program (ESP) and Brake Assist System (BAS). When it illuminates, it is signaling potential issues with these safety systems. Understanding the role of this warning light is critical to troubleshooting it.

The ESP is designed to enhance a driver’s control over the vehicle during adverse driving conditions. It does so by using sensors to monitor wheel speed and steering angle, adjusting the braking force of individual wheels to keep the vehicle on the driver’s intended path.

Conversely, the BAS optimizes braking performance during emergency braking situations, enhancing vehicle safety.

The ESP BAS light is interconnected with these features and several car sensors, including the steering angle sensor and wheel speed sensor. These sensors continually relay information about the vehicle’s driving condition and performance to the ESP.

If the sensors become faulty or defective, they may send incorrect signals to the ESP, causing the ESP BAS light to illuminate. Hence, seeing this light on your dashboard could be a sign of a malfunctioning sensor or issues with your car’s traction control system.

2. Identifying Possible Causes

The second step in the reset process is identifying the cause behind the ESP BAS light. There are a number of factors that could be responsible for triggering this warning light on your dashboard.

One possible cause could be an issue with the steering angle sensor. This sensor monitors the driver’s steering direction; if it goes bad, it could trigger the ESP BAS light.

A faulty wheel speed sensor is another common culprit. The wheel speed sensor provides crucial data about the rotation speed of each wheel, and a malfunctioning one can cause the ESP BAS light to illuminate.

The ESP BAS light could also be linked to a bad brake switch. The brake switch is responsible for activating brake lights when the brake pedal is pressed. If this switch fails, it could cause the ESP BAS system to misread braking actions, triggering the warning light.

Lastly, worn-out brake components, like rotors, pads, and calipers, can cause the ESP BAS light to come on. These components are fundamental to the braking system and wear and tear on them can affect overall braking performance, potentially activating the ESP BAS light.

3. Checking the ESP OFF Button

If your vehicle’s dashboard is graced with the persistent glow of the ESP BAS light, you might be able to rectify this issue by simply using the ESP OFF button, should your car model be equipped with one.

Some manufacturers provide this button to allow drivers to manually deactivate the Electronic Stability Program when desired. This function can come in handy during specific driving scenarios or when troubleshooting.

When you press the ESP OFF button, the ESP system is disabled, and consequently, the ESP BAS light should go off. To perform this step, you need to locate the ESP OFF button in your car. Depending on the car model, it is typically found on the dashboard or console.

Once located, you need to press and hold this button for a good five seconds. Some vehicles may require the ignition to be on, while the engine might need to be running in others. You need to consult your vehicle’s user manual to understand the specifics of your particular model.

If your attempt succeeds, the ESP BAS light will turn off, signaling that the issue has been temporarily rectified. However, it is essential to note that this is a temporary fix. If a faulty sensor or worn-out component is triggering the light, that issue will persist until resolved.

4. Preparing for the Steering Angle Sensor Reset

If checking the ESP OFF button didn’t extinguish the ESP BAS light, or your car does not have such a button, the next step involves conducting a steering angle sensor reset. The steering angle sensor plays a crucial role in your car’s ESP by determining the direction the driver intends to steer the vehicle.

Preparing to reset this sensor does not require any special tools or technical expertise. All you need are the keys to your car and a little understanding of how the steering angle sensor functions.

Before beginning the reset process, ensure your car is parked in a safe, flat area where you can turn the steering wheel without obstructions. The vehicle should be in a ‘ready to drive‘ condition, but it should remain stationary for the duration of this process. Depending on the vehicle model, you may need to start the engine or turn the ignition on.

Remember, safety is paramount, so ensure your surroundings are secure. Performing the reset is a simple process but requires your full attention. While it may not immediately solve the issue if the ESP BAS light’s cause is a more severe component failure, it is an excellent first step toward a potential solution.

5. Starting the Engine

The first requirement is to reset the steering angle sensor to start your vehicle’s engine. Ensuring that the engine is running facilitates the reset process, as it activates all the relevant electrical components and sensors, including the steering angle sensor.

Driver Turning The Ignition On

Before proceeding, ensure your car is in a secure location, your parking brake is on, and your vehicle is in the park or neutral position. Place your key in the ignition and turn it to start the engine.

For those with a keyless ignition, press the Start/Stop button. Keep your foot off the accelerator during this process to prevent unexpected vehicle movement.

Once the engine is running, observe the dashboard lights. The ESP BAS light should still be visible. If it disappears upon starting the engine, there might have been a temporary glitch, which has now been resolved. However, the sensor reset process should proceed as planned if it remains on.

6. Manipulating the Steering Wheel

Having the engine running now sets the stage for the next critical step: manipulating the steering wheel. This procedure is designed to reset the steering angle sensor, a fundamental component that feeds the Electronic Stability Program information on the car’s intended path.

Driver Holding The Steering Wheel

Once your engine is running, grasp the steering wheel and turn it as far as possible to the right. Make sure to turn it until it hits the steering stop. You should feel a firm resistance when the wheel has reached its limit. Do not apply force beyond this point to prevent damage to your car’s steering mechanism.

After you’ve reached the rightmost point, turn the steering wheel as far as it will go in the opposite direction, towards the left. Again, you should feel a firm resistance when the wheel can no longer turn. This back-and-forth motion is an integral part of the reset process for the steering angle sensor.

During this process, your car must remain stationary to prevent unintended movement. By manipulating the steering wheel like this, you’re providing the sensor with a full range of motion, which can help recalibrate it and potentially extinguish the ESP BAS light.

7. Repeating the Steering Wheel Manipulation

Once you have turned the steering wheel from its proper position to the extreme left, this action must be repeated to properly reset the steering angle sensor. Repeating this manipulation isn’t just for the sake of repetition; it has practical implications for the steering angle sensor’s reset process.

Driver Holding The Steering Wheel With One Hand

The steering angle sensor measures the direction and rate at which the steering wheel is turned. It then communicates this information to the car’s Electronic Stability Program. By turning the wheel from the rightmost to the leftmost position and repeating this action, you’re giving the sensor a full range of motion.

This range allows the sensor to recalibrate itself and more accurately determine the steering wheel’s angle. Typically, this process should be repeated about two or three times. Ensure you go from extreme right to extreme left each time, hitting the limit on both ends without exerting undue force on the wheel.

8. Returning the Wheels to Center Position

After completing the necessary cycles of steering wheel manipulation, it is vital to return the wheels to their center position. In this context, the center position means the steering wheel is positioned as it would be if the car were driving straight.

This step allows the steering angle sensor to register this middle point as the ‘zero’ position or baseline from which other angles are measured.

As you ease the steering wheel back to the center, do so with a steady and slow movement. Abrupt changes could disrupt the calibration process you’ve just completed. Take note of the ESP BAS light on your dashboard while you do this. Ideally, the light should go off when the wheel is returned to its center position.

When the steering wheel is straight, your car’s wheels should also align, pointing forward. If the ESP BAS light remains illuminated, it’s a clear sign that the problem might be more complicated than a simple sensor reset can fix. However, if it goes off, it indicates the sensor reset process has likely succeeded.

9. Verifying the Reset

The final and crucial step in this process involves verifying whether the reset has been successful. This is done by assessing if the ESP BAS light, which instigated this process, has been turned off. A successful steering angle sensor reset often extinguishes the dashboard’s ESP BAS light.

However, taking a short drive is recommended to confirm that the light isn’t merely off temporarily. This drive isn’t just to ensure the ESP BAS light stays off but also to see if the vehicle’s handling has improved, given that a malfunctioning steering angle sensor can affect the car’s stability and traction control.

Keep your drive short and stick to a familiar route where you can safely test the car’s response to steering inputs. As you navigate through the turns, pay attention to the car’s handling and the ESP BAS light’s status. If the light stays off and the car’s handling feels normal, it’s a strong indication that the steering angle sensor reset was successful.
