How to Deal with Vehicle Stability Control System Malfunction?
1 Answers
If the vehicle stability control system malfunctions, it indicates that the system is either turned off or experiencing a fault. If you accidentally pressed the ESP OFF button on the vehicle, simply press it again briefly to reactivate the ESP. However, if the ESP OFF light is on due to a system malfunction, immediate repair is necessary. Solutions for vehicle stability system malfunctions are as follows: 1. Replace the throttle body: If the throttle actuator is stuck in the closed position and the ECM commands the throttle to open but the actuator remains stuck, check the electronic throttle fuse and wiring harness. If these are fine, measure the resistance between pins 1 and 2 (throttle motor coil). If abnormal, replace the throttle body. 2. Decode the fault code: If the vehicle stability system shows an electronic control system fault, use a diagnostic scanner at a repair shop to read the fault code and proceed with repairs. 3. ESP system: The ESP system consists of a control unit and various sensors, including a steering sensor (monitors the steering angle of the steering wheel), wheel sensors (monitor the speed of each wheel), a yaw sensor (monitors the vehicle's rotation around the vertical axis), and a lateral acceleration sensor (monitors centrifugal force during turns).
