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.

GENERAL INFORMATION
SMART WIRING SYSTEM (SWS)54B-2
GENERAL INFORMATION
M2541000100424
SWS is a minimal line system which transmits
numerous signals using one wiring.
To transmit numerous signals, the ETACS*1-ECU,
column switch (incorporating inside the col
-
umn-ECU) incorporate multi-distribution circuits to
carry out communication between control units.
ETACS-ECU can receive some input signals through
CAN
*2 communication, improving the SWS function.
NOTE: *1: ETACS (Electronic Time and Alarm Con-
trol System)
NOTE: *2: CAN (Controller Area Network)
For more information, refer to GROUP 54C P.54C-2.

GENERAL
ACTIVE STABILITY CONTROL SYSTEM (ASC)35C-2
GENERAL
M2357000200040
The active stability control system (ASC) has been
installed to the M/T vehicle.
•The active stability control system (ASC) has the
stability control and the traction control (TCL)
functions. By the integrated control with the
anti-lock brake system, the system stabilises the
vehicle attitude and at the same time secures the
driving force.
•When the stability control function determines
that the vehicle is in a dangerous condition, it
reduces the engine output and applies brake
force to four wheels independently to control the
vehicle behaviour, avoiding the critical state.
•The traction control (TCL) function prevents the
driving wheel slip on a slippery road surface,
ensuring easy startup, and at the same time,
secures proper driving force and improves steer
-
ing performance during cornering acceleration.
•Fail-safe function assures the security.
•Serviceability improvement
•For wiring harness saving and secure data com-
munication, the CAN* communication has been
adopted as a tool of communication with another
ECU.
NOTE: .
•*For more information about CAN (Controller
Area Network), refer to GROUP 54C
P.54C-2.
•ABS and ASC are controlled by ASC-ECU.
