Description of On-Board Diagnostics

SYSTEM COMPONENT





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

EBD (Electronic Brake-force Distribution)
The EBD is additionally applied instead of the proportioning valve to make the ideal distribution of a fluid pressure to the front and rear brake to prevent the break from skidding in the event of rearwheel lock and to obtain a higher brake efficiency within the range of service brake application.

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