25 - BRAKE CONTROL SYSTEM
4. Shorten brake distance effectively.
Operation
ABS Braking
1. If ABS system detects that the wheels may be locked when applying brake, the brake system will enter
ABS braking mode. During braking, ABS control module outputs signal from each wheel speed sensor to
each solenoid valve after analysis in order to adjust the fluid pressure in each line, to prevent the wheels
from being locked.
2. There are some operating symptoms of ABS that seem to be abnormal at first, but in fact they are normal.
The symptoms are as follows:
a. If the electronic control module is malfunctioning, fail-safe function will be activated, ABS system will
not operate and ABS warning light will come on.
b. After vehicle is power on or engine is started, short "buzz" sound can be heard, which is the ABS 
self-check sound, and this is normal.
c. Noise caused by the corresponding solenoid valve movement when EBD is involved in braking can be
heard, but this is normal.
d. Brake pedal may vibrate slightly and mechanical noise can be heard during ABS operation, but this is
normal.
e. Braking distance may be longer than that of vehicles without ABS when braking on rough, sandy, or
snow-covered roads.
