What does the yellow OFF light on the dashboard mean?
1 Answers
Car dashboard yellow light OFF means closed, ON means open. The OFF light on the car mainly refers to ESP OFF. ESP stands for Electronic Stability Program, which is an active safety device mainly used to prevent the vehicle from skidding and fishtailing. If the ESP OFF light on the car dashboard lights up, it means that the vehicle's electronic stability control system is turned off or malfunctioning. If you accidentally press the ESP OFF button on the vehicle, you can turn the ESP back on by pressing it again briefly. If the ESP OFF light is on due to a system malfunction, you should send the vehicle to a 4S shop for repair in time. There are many reasons for the malfunction light to come on, such as circuit failure, sensor damage, electronic control unit signal error, battery power loss, etc. ESP is particularly sensitive to oversteer or understeer. For example, when the car turns left too sharply (oversteer) on a slippery road, it will fishtail to the right. The sensor will sense the skid and quickly brake the right front wheel to restore traction, generating an opposite torque to keep the car in the original lane. The difference between a car with ESP and one with only ABS and ASR is that ABS and ASR can only react passively, while ESP can detect and analyze the vehicle condition and correct driving errors, preventing problems before they occur.
