What does it mean when the ESP warning light is on?
1 Answers
The reasons for the ESP warning light being on are: 1. When the ESP light on the dashboard illuminates, it indicates that the vehicle's electronic stability system may have malfunctioned, or it could be caused by damage to other functions. In such cases, it is recommended to send the vehicle to a 4S shop for inspection as soon as possible; 2. The ESP system involves many sensors, so the general cause of failure is usually related to the sensors. It could be due to loose wiring connections causing sensor function failure or false alarms; 3. ESP, also known as Electronic Stability Program, analyzes information about the vehicle's driving state transmitted from various sensors and then sends correction instructions to systems like ABS and EBD to help maintain the vehicle's dynamic balance; 4. The ESP system mainly consists of three parts: sensors, actuators, and the electronic control unit (ECU). The sensors generally include wheel speed sensors, steering wheel angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. The actuators typically include traditional braking systems and hydraulic regulators. The electronic control unit works in conjunction with the engine management system to intervene and adjust the engine's power output.
