When the ABS light on the Elantra dashboard is illuminated, it indicates a malfunction in the vehicle's Anti-lock Braking System. The working principle of ABS is: during emergency braking, the system relies on highly sensitive wheel speed sensors installed on each wheel to detect wheel lock-up. The computer then controls the pressure regulator to release pressure from the wheel's brake cylinder, preventing wheel lock-up. The functions of ABS are: 1. To prevent loss of vehicle control, increase braking distance, and enhance vehicle safety; 2. To improve the overall braking performance of the vehicle; 3. To prevent wheel lock-up during braking; 4. To ensure the driver can control the direction during braking and prevent rear axle skidding.
