ESP BAS Light – How to Turn It Off? Best Guide

The ESP and BAS are essential safety features in modern vehicles. These systems enhance vehicle stability, control, and braking performance. With the advancement of technology, automotive manufacturers have been incorporating ESP BAS into their cars to provide an added layer of safety for drivers and passengers alike.

As with any technological feature, there is always a debate about its effectiveness and whether it is worth the investment. We will delve into the ESP BAS light feature and evaluate its benefits and drawbacks to determine if it is a good choice for car owners looking to prioritize safety on the road.

What Is the ESP BAS Light?

The initials ESP stand for Electronic Stability Program, while BAS refers to Brake Assist System. When these light turns on, it typically means an issue with one of these systems.

These safety features prevent accidents and enhance vehicle control by applying braking force selectively to individual wheels. When the emergency brakes are engaged, these light can turn on due to the system detecting sudden changes in wheel speed.


When illuminated on your dashboard, this light indicates a potential malfunction in either the brake assist program or the electronic stability program. These two systems are crucial for maintaining control and stability while driving, especially during sudden braking or tricky road conditions. 

You must immediately act if you notice these light turning on. The malfunction could compromise your vehicle’s safety features and impact its overall performance. Ignoring this warning may put you at risk of losing control of your car during critical moments when you need maximum assistance from these programs.

Reasons Why It Turns On

You can unlock information hidden within your car’s computer with the proper diagnostic tool. Scanning the vehicle’s system can reveal and diagnose a lot, shedding light on potential issues that may have triggered that unwelcome warning. 

This detailed information allows mechanics and technicians to quickly pinpoint the source of the problem and take appropriate action for repair. Thanks to reasonably priced instruments available on Amazon, identifying and troubleshooting the reasons behind these lights turning on has become more accessible than ever. 

Worn-Out Rotors, Pads, and Calipers

These lights can be unwelcome on your dashboard, signaling potential issues with your vehicle’s braking system. One of the main culprits behind this warning is worn-out rotors.

The constant friction between the brake pads and rotors can cause them to become thin and unevenly worn. When this happens, it affects the overall performance of your brakes and triggers these lights to illuminate.

Worn-out rotors, another common cause for the ESP BAS light to turn on is deteriorated brake pads. As you apply pressure on your brakes repeatedly over thousands of miles, these pads gradually wear down until they reach a point where they need replacement.

Bad Brake Switch

A faulty brake switch is one of the primary causes behind the dreaded these lights turning on in your vehicle. These switches, notorious for their unreliability, can lead to issues with your car’s electronic stability program (ESP) and brake assist system (BAS). A defective brake switch can disrupt the communication between these vital safety features and result in an illuminated warning light on your dashboard.


When a brake switch malfunctions, it often fails to detect when you engage or release the brakes accurately. This discrepancy leads to confusion within the ESP and BAS systems, causing them to activate unnecessarily or fail to engage when needed.

You may experience unexpected automatic braking, or your vehicle may lack sufficient assistance during emergency stops. It is crucial to address this issue promptly as it jeopardizes your safety on the road and potentially expensive repairs.

Bad Wheel Speed Sensor

Your car is equipped with several essential sensors that work together to ensure your safety on the road. These crucial sensors is the wheel speed sensor, which measures the average speed of each wheel.

This information is essential for systems like ESP and Brake Assist Systems (BAS), as they rely on accurate data from these sensors. When your car’s wheel speed sensor malfunctions or goes wrong, it can trigger various issues, one of which includes the illumination of these light on your dashboard.

Steering Angle Sensor

Modern automobiles are equipped with a wide array of sensors and cutting-edge technologies geared toward enhancing the driving experience. One such sensor is the steering angle sensor, which ensures the vehicle’s stability and safety. It is not uncommon for this sensor to malfunction or turn on unexpectedly, causing concern among drivers. 


There can be several reasons why the steering angle sensor turns on. It could be due to a faulty connection or wiring issue. Wires can become frayed or damaged, leading to intermittent signals or complete failure of the sensor. Extreme temperature fluctuations can also affect its performance.

Another common cause is dirt and debris accumulating around the sensor area, interfering with its proper functioning. Issues with other components in the vehicle’s electronic stability control system may also trigger the steering angle sensor warning light.

Can I Still Drive With The ESP Light On?

Driving with the ESP light on is generally safe, although it indicates that there may be an issue with your vehicle’s electronic stability program system. When the ESP light comes on, it usually means that either the system needs to be reset or you have manually turned it off. In either case, you can still operate your vehicle without significant concerns for your safety.

If the ESP light is on due to a system malfunction, it is advised to get your vehicle checked by a professional mechanic as soon as possible. A malfunctioning ESP system may temporarily reduce its effectiveness in certain driving conditions but should not pose an immediate danger.

It is important to note that with the proper functioning of the ESP system, you may experience increased stability and control during maneuvers such as sudden turns or emergency stops.

How Do I Get Rid Of the ESP BAS Light?

Are you tired of seeing these light illuminated on your dashboard? Don’t worry; there’s a simple solution to eliminate it. You can end this annoying light by performing a quick and easy steering angle system recalibration. All you need to do is turn the wheel four times to the right, repeat the same motion four times to the left, and finally return it to the center for another four turns. 

This process will reset your vehicle’s electronic stability program and brake assist system, responsible for maintaining control and stability during sudden maneuvers or slippery conditions.

These systems can become misaligned for various reasons, such as battery replacement or driving over rough terrain. When this happens, these lights may be a warning sign that something isn’t quite right.

Cost to Repair the BAS Light

Before worrying about repairing the BAS light, you must know what you might be looking at regarding expenses.  According to recent data, the price range for replacing an ABS pump can vary significantly. On the lower end of the spectrum, some mechanics may charge as little as $290 for parts and labor.

If you’re dealing with a more complex or high-end vehicle model, the cost can skyrocket to $1,100 or even higher. As always, consulting multiple service providers and comparing quotes is crucial before settling on one option.


The ESP BAS light in your vehicle is a safety feature that helps to prevent accidents and maintain control. Understanding what it means and how to respond when it illuminates is essential. By following the steps outlined in this article, you can determine whether your vehicle has a genuine issue or if it simply needs a reset.

Consider your vehicle’s manual for specific instructions tailored to your make and model. Being proactive about maintaining and understanding your car’s warning lights will contribute to a safer driving experience for you and others on the road.


Can I still drive my vehicle with these light on?

Yes, you can still drive your vehicle; it is recommended to have it checked by a mechanic as soon as possible to diagnose and fix the underlying problem.

Is it safe to turn off the ESP BAS system permanently?

Removing the ESP BAS system is only recommended if a professional mechanic advises. These systems are designed to enhance safety during driving conditions, and disabling them may compromise your security.
