The ESP warning light is an indicator of the proper functioning of the anti-skid system. However, if it remains on throughout your drive, it may also indicate a system malfunction.

The ESP warning light came on
Like all other dashboard warning lights, the ESP light appears when you turn on the ignition.
However, it disappears after the ECU has verified the status of the anti-skid system.
It can also illuminate while driving when the vehicle is understeering or oversteering, helping you maintain control and prevent skidding.
What an illuminated ESP warning light indicates
The warning light typically appears on your dashboard for two reasons:
- At startup, to ensure the anti-skid system is functioning correctly.
- While driving, to help maintain proper road handling.
However, in both cases, the light should not stay on for long.
If your ESP light remains on throughout your journey, this is a sign of a system malfunction.
Is it dangerous to drive with the ESP warning light on?
The dashboard warning light activates when it detects a fault in the vehicle's anti-skid system.
If the fault leads to a system failure, it can be hazardous.
Since this system helps maintain control of the car, driving without its assistance increases the risk of losing control and going off the road.
ESP warning light: how to turn it off?
Since the warning light indicates a fault, it must be cleared.
The most common reason for the light turning on is a blown bulb.
This creates a sensor malfunction, causing it to constantly detect a hazard.
However, it is best to precisely check the cause of the illuminated warning light.
If it is indeed a significant system fault, you risk losing control of your vehicle.
Common failures in the system related to the ESP warning light
The anti-skid system consists of multiple sensors managed by an ECU.
If the warning light stays on, the ECU data must be analyzed to identify the faulty sensor(s).

Sensors that could cause the malfunction
- The steering angle sensor, which records the steering wheel's rotation angle.
- The lateral acceleration sensor, which detects any abnormal lateral movements.
- The yaw rate sensor, which analyzes the vehicle's rotation around an axis and detects loss of traction risks.
Conclusion
The ESP warning light can appear on the dashboard for various reasons. However, it is always essential to ensure its proper function before driving.
