Description of On-Board Diagnostics

SYSTEM COMPONENT





The Anti-Lock Brake System (ABS) controls the hydraulic brake pressure of all four wheels during sudden braking, and braking on hazardous road surfaces, preventing the wheels from locking up. ABS provides the following benefits.
1. Enables steering around obstacles with a greater degree of certainty, even during emergency braking.
2. Enables stopping during emergency braking while keeping stability and steerability even on curves.
If a malfunction occurs, a diagnosis function and fail-safe system are included for serviceability.

EBD (ELECTRONIC BRAKE-FORCE DISTRIBUTION)
EBD is additionally applied,instead of the proportioning valve,to deliver ideal distribution of fluid pressure to the front and rear brakes. This prevents the brakes from skidding in the event of rear wheel lock up and provides higher brake efficiency within the range of brake application.

ADVANTAGES
- Functional improvement of base-brake system
- Compensation of different friction coefficients
- Elimination of proportioning valve
- Failure recognition by warning lamp
