What are the causes of VSC system failure?

[MacWeston]

VSC system failure may be caused by: 1. Abnormal or faulty ignition coil; 2. When the VSC system warning light comes on, it doesn't necessarily mean the VSC system itself has failed. It could also indicate issues with other systems like ABS or ASR. VSC is an active vehicle safety system developed by Toyota, which significantly improves vehicle handling safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, or hard braking, the system can quickly detect the situation and take appropriate braking measures, such as individually controlling each wheel while reducing engine output to maintain vehicle stability. When the VSC warning light illuminates, it's often accompanied by other warning lights. The issue can only be properly diagnosed by connecting to an OBD scanner to read fault codes. It's recommended to take the vehicle directly to an authorized 4S dealership for inspection and repair.
