When the car's ESP light stays on, it is alerting the owner that there may be a malfunction in the vehicle's stability control system, which requires prompt inspection and repair. ESP stands for Electronic Stability Program, which is an active safety system in vehicles. It is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functionalities. The ESP system mainly consists of a control unit, steering angle sensor, wheel speed sensors, yaw rate sensor, and lateral acceleration sensor. ESP enables automatic safety control of the vehicle, effectively improving driving stability and safety during dynamic conditions such as braking, acceleration, and steering.
