What to Do When the VSC System Fails? Can You Still Drive?
3 Answers
When the car displays a VSC system failure, you can continue driving, but it is essential to have it inspected and repaired as soon as possible. Below are the related causes and solutions for VSC system failures: 1. Accidental Press of the OFF Button: The VSC system is developed based on ABS. It primarily operates under extreme conditions with large lateral acceleration and significant sideslip angles, utilizing the yaw torque generated by the difference in braking force between the left and right sides to prevent uncontrollable skidding. If the OFF button is accidentally pressed, the VSC system will be deactivated. Solution: Locate the OFF button and restart the car. 2. Indicator Light Malfunction: If the indicator light malfunctions, it may cause the VSC system warning light to illuminate, even though the VSC system is still functioning normally. Solution: Visit an authorized 4S shop for indicator light repairs.
When the VSC system warning light comes on, I recommend pulling over immediately to check. This system is crucial for preventing skidding and loss of control, especially when cornering in rainy conditions. Once during a business trip, I encountered this situation - the dashboard warning light came on and the car felt unstable, so I immediately slowed down to under 60 km/h before driving to the service area. The inspection revealed a loose wheel speed sensor connector, which was fixed by firmly reconnecting it. Continuing to drive could easily lead to skidding during high-speed lane changes or on wet roads. The mechanic mentioned that most VSC failures are sensor-related, but a computer diagnosis is needed to confirm - never try to make do by randomly pulling fuses.
Last time my car showed a VSC malfunction was on a mountain road, and I immediately felt less stable steering control. If conditions permit, it's best not to continue long-distance driving, especially on downhill curves or icy roads, as system failure increases rollover risk. For temporary measures, try turning off the engine for half an hour and restarting - sometimes the electronic system can reset itself. If you must drive, it's recommended to turn off cruise control, maintain steady speed, and avoid emergency lane changes. If no repair shop is available, you could try disconnecting the negative battery terminal for one minute to reset the system, but this is only for emergencies. Remember to maintain proper tire pressure - this malfunction is particularly dangerous when traction is insufficient.
