What does it mean when DSTC appears and needs repair?

[StMalachi]

When DSTC appears and requires repair, it indicates a fault in the ABS anti-lock braking system. Below are specific details about the ABS system: 1. Function of the ABS system: ABS is the vehicle's anti-lock braking system, which is part of the car's active safety system. When the ABS light comes on, it means the car's computer has detected a fault in the ABS system. 2. Reasons for the ABS light turning on: Under normal driving conditions, the ABS remains dormant. It only activates during emergency braking, such as during high-speed hard braking, when the car's computer determines that ABS intervention is necessary. When the ABS light comes on, it is often due to the wheel speed sensors not functioning properly. The ABS computer cannot detect the driving conditions of each wheel, making it unable to compare the slip amounts of each wheel, which results in the ABS system not working correctly.
