ANTI-SKID BRAKE SYSTEM (ABS)
The ABS ensures directional stability and controlla-
bility during hard braking.
For vehicles with this type of ABS, 4 sensors are
installed on front and rear wheels allowing independ
-
ent left and right control.

The syst
em has the following features:
•EBD (Electronic Bra ke-fo rce Distributio n system)
co ntrol has been added to provide t he ideal brak
-
in g force for th e rear wheels.
•Magnetic en coder for whee l speed de tection ha s
bee n inst alled as a se nsing device instead of the
rotor .
•For wiring h arness saving an d secure data com-
municatio n, CAN* b us h as be en ad opted a s a

•The
active st ability control syst em (ASC) has the
st ab ility control and t he traction control (TCL)
fun ctio ns. By the integra ted control with th e
ant i-lock b rake system, the system stabilizes th e
ve hicle attitu de and at the same time secures the
drivin g force.
•When the st ability control fun ction dete rmin es
tha t the vehicle is in a dangerou s condition, it
redu ces the e ngine outpu t and a pplies b rake
force to f our wheels indepe ndently to control th e
ve hicle be haviour, avoiding the critical state.
•The tract ion control (TCL) fun ction prevent s the
drivin g wheel slip on a slippery road sur face,
ensurin g easy st artup, an d at the same time,
secure s proper drivin g force and improves ste er
