ESP BAS Light On? Here’s What It Means and What to Do

Imagine yourself on a picturesque road trip with your loved ones on a sunny day. Your dashboard suddenly lit up with the letters ESP BAS. You can tell there’s an issue since your dashboard is cluttered with warning lights. Mechanical or electrical issues can be at the root of these problems.

What Does ESP BAS Light Mean?

ESP The BAS Light is a dashboard warning light that discusses ESP and BAS. Any dashboard light or figure that comes on means that something is wrong with your vehicle. Any kind of defect, no matter how little, has the potential to trigger catastrophic failure.
The abbreviation “ESP” stands for the Electronic Stability Programme. In other automobiles, it’s called Electronic Stability Control (ESC). In emergency scenarios, it is a computer-controlled programme that provides support to the driver.

In order to achieve this, it detects when the car is losing traction or skidding and acts accordingly. There are a number of technologies that work together to combat traction concerns; they include the antilock braking system (ABS), traction control, and many more.

Conversely, the Brake Assist System goes by the acronym BAS. It assists in applying more force to the brakes in response to a sudden slam of the pedal.

It is common practice to slam on the brakes in an emergency. In such cases, the Brake Assist System—also known as the Brake Assist program—can detect the level of pressure, velocity, and acceleration exerted by your foot on the brake pedal.

It will then release the ideal amount of pressure on the brake pads without using your brake, all the while waiting for the Anti-lock Braking System (ABS) to activate.

A dashboard warning light may illuminate upon starting your vehicle and then go off shortly after. But if any alert lights stay on for an extended period of time, it indicates that the associated component is malfunctioning. For example, if the ESP BAS light is on, it means that the electronic stability or braking assist system is malfunctioning.

What causes ESP BAS Light to come on?

We already established that the presence of a warning light signifies the presence of an issue. The Electronic Stability Control (ESC) or Brake Assist System (BAS) may be malfunctioning when the ESP BAS indicator is illuminated.

Maybe this is just a small problem that you can fix yourself using an OBD scanner. You may see the ESP BAS light on your dashboard if any of these problems are present.

  • Failure in the Brake Switch
  • Faulty Steering Angle Sensor
  • Faulty Wheel Speed Sensor
  • Bad Brake Pads and Calipers
  • Electrical Faults

How do I fix the ESP BAS light?

Because electrical issues are the most common culprits, fixing the ESP BAS light is a breeze. An OBD diagnostic tool can identify the source of the problem, as is the case with the majority of electrical failures. You can find out what might be causing it with the scan tool. Wheel speed sensor, steering angle sensor, or brake switch failure could be the culprit.
Determine what is causing the ESP BAS warning light and either fix it or replace it. Scanning the car again and clearing the code will follow. If you are not comfortable working on your vehicle on your own or are unfamiliar with the inner workings of your vehicle, it is best to contact a mechanic.
