ABS, or 'anti-locking braking system' is an additional braking safety system to help improve vehicle control whilst braking in an emergency situation. If the ABS warning light comes on, normal brake will continue to work as usual. Have system checked as soon as possible to restore these safety features. Faults are usually due to ABS wheel speed sensors.
Kia Optima EBD Warning Light
EBD
Name: Kia Optima EBD warning light.
Description: EBD stands for Electronic Brake Force Distribution and is responsible for applying brake pressure on individual wheels. The system uses the ABS to determine the correct amount of pressure to apply. EBD helps to improve vehicle stopping ability.

▷ Flashing means the ESC system is in operation and attempting to stabilize the vehicle.
▷ Constantly on means there's a fault with the system. Due to the ESC system using ABS sensors, the ABS system may be dysfunctional.
