How to Turn Off the VSA Vehicle Stability Control System Light?

It may indicate a malfunction in the electronic stability control system, which requires troubleshooting at a repair shop to resolve. Here is some related information about the vehicle stability control system: 1. System Introduction: The vehicle stability control system, also known as the anti-skid control system (Skid-Control-System), was first adopted in domestic vehicles by Toyota's Corolla-Altis (Toyota refers to it as VSC). Currently, higher-priced domestic vehicles commonly feature this system. The vehicle stability control system is an active safety system that includes ABS and ASR, preventing wheels from locking during braking (ABS) and slipping during acceleration (ASR). 2. Working Principle: When a car is turning, if the front wheels reach their adhesion limit first, it can cause a "drift-out" phenomenon. In this situation, no matter how the driver steers, the turning radius cannot be reduced, making it difficult to follow the intended path and resulting in understeer. If the rear wheels reach their adhesion limit first, a "fishtail" phenomenon occurs, making the car unstable and quickly pulling it toward the turning side, known as oversteer.
I remember feeling a bit nervous when this light came on while driving my friend's Accord last time. The car started flashing this light after making a sharp turn in the rain, so I immediately slowed down and pulled over. I checked the buttons near the steering wheel and found that the VSA Off switch had been accidentally pressed—turning it back on fixed the issue. If the light stays on, the system might have detected a fault with the ABS sensor or wheel speed sensor, so you'd need to check if the wiring or sensors are dirty or damaged. I wouldn’t recommend forcing the light off while driving, as VSA helps prevent wheel slippage—if the light is on, the system might not be working, which is risky on slippery roads. I also make sure to clean the sensor areas during regular maintenance to avoid false alarms from dirt buildup. In short, try the manual button first, and if that doesn’t work, take it to a professional shop to scan the trouble codes and repair it.
