What does a car ESC system malfunction mean?
1 Answers
When the ESC warning light illuminates, possible causes include: 1. Faulty sensors in the ESC system, such as the yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor. 2. Issues with the system's wiring, including short circuits or open circuits. 3. Malfunction of the control unit itself. Below is relevant information about the ESC system: 1. Definition: The ESC system is the Electronic Stability Control system, a new active safety system for vehicles. It primarily includes the functions of the Anti-lock Braking System (ABS) and Traction Control System (TCS), and additionally incorporates a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor when the vehicle is turning. 2. Function: The system ensures lateral stability by detecting understeer or oversteer through signals from the steering angle sensor, lateral acceleration sensor, and wheel speed sensors. It then controls one or more wheels to apply braking, adjusting the vehicle's body posture during lane changes or cornering, making the car more stable and safe when changing lanes or navigating curves.
