What Causes the Vehicle Stability Control System Light to Illuminate?

[MacReed]

The illumination of the Vehicle Stability Control System light indicates a malfunction in the vehicle's ESP (Electronic Stability Program). When the ESP light comes on during driving, it is necessary to reduce speed, avoid excessive steering and turning, and promptly locate a nearby 4S dealership to diagnose the issue. ESP, or Electronic Stability Program, is an automatic vehicle stability control system. The ESP system primarily consists of three major components: sensors, actuators, and the electronic control unit (ECU). Sensors typically include wheel speed sensors, steering angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. Actuators generally comprise conventional braking systems and hydraulic controllers, while the electronic control unit interacts with the engine management system to intervene and adjust engine power output. Common ESP malfunctions include: ABS pump failure and ABS pump power supply grounding circuit faults, loose sensor connectors or failure of a specific sensor function, related fuse blowouts or burnouts, obstruction of system signal transmission, false faults (system false alarms). Try pressing the off button to restart the system.
