The solutions for the stability control system failure preventing the car from starting are as follows: 1. Generally, this occurs when the system detects an ESC fault during power-on self-test, thus preventing ignition. The ESC module must be checked and confirmed to be functioning properly before ignition is allowed; 2. The Electronic Stability Control (ESC) is a new active safety system in vehicles, which is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functions. It additionally incorporates a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor during cornering. Through the ECU, it controls the driving and braking forces of all four wheels to ensure lateral stability during vehicle operation; 3. This system consists of three main components: sensors, Electronic Control Unit (ECU), and actuators. The ECU monitors the vehicle's operational status and intervenes to control the engine and braking system. A typical ESC system includes sensors such as four wheel speed sensors, steering wheel angle sensor, lateral acceleration sensor, yaw rate sensor, and brake master cylinder pressure sensor. The actuator components include conventional braking systems (vacuum booster, pipelines, and brakes) and hydraulic modulators. The ECU works in conjunction with the engine management system to intervene and adjust engine power output.
