What Do ESP BAS Mean on a Car Dashboard?

January 5, 2024

When the letters ESP BAS appear on your dashboard, it means there is something wrong with your car's Electronic Stability Program and Brake Assist System. This system is a computer-controlled program that supports the driver in critical situations, such as skidding movement or loss of traction. The ESP system includes the traction control system and antilock braking system (ABS), while the BAS is in charge of increasing the brake pressure to help drivers during emergency braking.

The ESP/BAS warning light can be triggered by a variety of issues. One common problem is a faulty steering angle sensor, which can cause the system to report incorrect information. This can also happen if the brake switch sensors or wheel speed sensors are not working properly. If this is the case, you'll need to replace these parts.

Another common issue is a depleted brake pad or brake caliper. When these components are not in good shape, they can't supply enough pressure to the wheels. In addition, they can also send false signals to the ESP/BAS system.

If the ESP BAS warning light appears on your dashboard, you should stop driving your vehicle until you get to a mechanic. The light indicates that there is a problem with the electronic stability program and brake assist system, which can be dangerous when driving in slippery conditions. Fortunately, this problem is usually easy to resolve, so you should not have too much trouble fixing it.
