ESP Bas Light? What is it all about? ESP is short for Electronic Stability Program, while Bas is short for Brake Assist Programs. So ESP Bas Light is a trouble indicator light that indicates that there is an issue with your Dodge Charger’s Electronic Stability Program and/or your Brake Assist Program. And these systems are important to the safety of your Charger.
However, if all of a sudden the ESP BAS pop up while driving, If you’re not familiar with the significance of these warning lights, you must be eager to learn more about the lights. Which is the reason for this write-up.
ESP Bas Light
ESP is mostly known as the Electronic Stability Control in various automobiles. While some refer to it as Dynamic Stability Control. Also, It’s a computer-controlled system that’s designed to improve the stability of your car.
Thus, by recognizing a lack of traction and assisting you to rise back in it to maintain optimum control of your car and possibly hazardous situations. So, whenever your electronic stability program senses a loss of traction, it immediately activates your brakes to enable you to steer your car more effectively.
BAS is a system that increases the pressure on the brakes while attempting to stop immediately. It is capable of detecting the intensity with which you’re braking, as well as the speed and power with which you’re pushing the brake pedal to alert you to a potentially dangerous situation. However, if yours is switched on, it might indicate some issues with your car that needs to be addressed.
Common Reason Why ESP BAS Light Is On
The ESP BAS Light indicates an underlying problem with your car’s electronic stability program or the brake assist system (ESP BAS System). It functions similarly to the other warning lights on your dashboard, notifying you of an issue. Below are some of the reasons for the ESP Light Staying on.
Faulty Steering Angle Sensor
A faulty steering angle sensor is the main cause of the ESP BAS light illuminating. The steering angle sensor’s function helps your car’s steering wheel in operating in unison with your wheels or tires on the ground. However, this steering wheel sensor verifies that the wheels of your vehicle are rotating in the proper orientation.
So whenever an issue occurs, the light on your dashboard will begin to flash. When the light is switched on, it may be due to the sensor being disengaged. But, if the light goes out, it indicates that the sensor’s contact has been re-engaged.
How to Fix the Faulty Steering Angle Sensor Problem
Solutions for this sensor-specific issue are a simple matter. To start the troubleshooting, use an ohm-meter to examine the sensor’s connections. A good reading shows that the sensor is in excellent condition. A bad reading means a faulty steering angle sensor, and you might need a professional’s hand to deal with such an issue.
Procedure; turn your car’s steering wheel to the left direction two times and then to the right, also two times. Then, place the steering wheel back in the middle to ensure that the wheel faces forward. Eventually, your steering angle sensor will resume regular operation, and simultaneously, the ESP BAS light would switch off, allowing you to drive normally.
Failing Brake Switch
Brake switches are renowned for failing often. A brake switch operates in an easy manner. Once you click the brakes, this switch activates the rear brake lights. However, a brake switch is required for the system to function so that any vehicle behind you will recognize when you come to a complete stop.
So, whenever it fails, the sensor alerts you that it is due to replace. Which is the reason why your ESP BAS light is on, and you must address the problem immediately.
How to Fix Failing Brake Switch Problem
Routine maintenance will help determine whether or not the brake switch is defective.
Procedure; to get started, use an OBDii scanner to get the diagnostic trouble codes and identify the problem. The code is located just over the vehicle’s brake pedal. Then, disconnect the defective brake switch and replace it with a new one. Finally, the code must be reset.
Bad Wheel Speed Sensor
All the wheels of your car come with a speed sensor that monitors your speed. It assists the ESP BAS system in determining when you have lost traction. This traction loss may happen if you drive over icy surfaces, rocks, or other unstable terrains. So, when this happens, your wheel speed sensors can detect unusual readings. While the ESP system will engage and provide pressure to a specific wheel that has lost traction.
However, it will assist in restoring the car’s stability and keeping it on the right track. Whenever the light does not go off, it shows that one of your wheel sensors could be malfunctioning.
How to Fix Bad Wheel Speed Sensor
To replace a malfunctioning wheel speed sensor is very easy and they’re inexpensive, so you won’t have to blow the budget. To fix the problem, kindly change the sensors. After replacement, verify that the ESP BAS light has been switched off.
Damaged Brake Components and wiring problems are also other reasons why you may see the ESP Bas Light.
Driving With ESP BAS Light – Does it have any Disadvantages
Driving with ESP BAS light illuminated is very dangerous and should be avoided. However, you need to fix the problem immediately to ensure your safety. Though it could be somewhat minor, or it could be something serious. But the ESP system must function well at all times since you hardly know when you will really need it.
Further, a malfunctioning ESP system could result in a disaster. Traction needs to keep the automobile on the road. So, once these sensors fail, you risk losing traction in sharp turns or on snow. And no one knows what kind of road conditions you might encounter. You must constantly be ready for these occurrences.
How to Turn Off ESP BAS Light
Switching off the light is easier than turning off most other dashboard warning lights, unlike the check engine light. And, the moment you were able to know why your vehicle’s ESP BAS light is activated, you can move toward turning it off.
- Employ a code scanner to get the vehicle’s primary computer’s fault codes or engine codes.
- Find out what is prompting the ESP BAS light to illuminate.
- Then, go for the required repairs to your vehicle to turn off the ESP BAS light.
- Normally, after an hour or two, you may be able to switch off an ESP BAS light.
I believe you’ve learnt a lot about the ESP Bas Light. Now you have tips on causes and solutions to ESP Bas Light issues.
