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.

ComponentNo.Function
SensorWheel speed sensor1Sends alternating current signals at frequencies which are
proportional to the rotation speeds of each wheel to the
active stability control system-ECU
Magnetic encoder for wheel
speed detection2The wheel speed sensor is a pulse generator. When the
magnetic encoder for wheel speed detection (a plate on
which north and south pole sides of the magnets are
arranged alternately) rotates, it outputs frequency pulse
signal in proportion to each wheel speed.
Stop lamp switch3Sends a signal to the active stability control system-ECU
to indicate whether the brake pedal is depressed or not.
Parking brake switch4Outputs the signal indicating whether the parking brake
lever is pulled or not to ASC-ECU.
Brake fluid level switch5Outputs the signal indicating whether the brake fluid is
filled to the lowest limit level or not to ASC-ECU.
G and yaw rate sensor6Detects the lateral acceleration and the yaw rate for the
vehicle. Then it sends a signal through the CAN bus line to
the active stability control system-ECU.
Steering wheel sensor7Detects the steering wheel angle, and sends a signal to
the active stability control system-ECU through the CAN
bus line.
ASC OFF switch8Outputs the ASC ON/OFF signal to ASC-ECU.
Pressure sensor9Is incorporated in the hydraulic unit, and informs the active
stability control system-ECU of the brake fluid pressure in
the master cylinder.
ActuatorHydraulic unit10Drives the solenoid valves and pump motor according to
signals from the ABS/active stability control system-ECU in
order to control the brake hydraulic pressure for each wheel.
ABS warning lamp11Illuminates in response to signals from the active stability
control system-ECU when a problem develops in the
system.
Brake warning lamp12Illuminates in response to signals from the active stability
control system-ECU when a problem develops in the EBD
system or the brake fluid level is low.
Active stability control system
(ASC) indicator lamp 13Receives a signal from the active stability control
system-ECU, and flashes to inform the driver that the
system is operating, or illuminates to inform the driver of
system shutdown.
ASC OFF indicator lamp14Informs the driver of the ASC shutdown by illuminating
with the signal from ASC-ECU.
Diagnosis connector15Sets the diagnosis codes and allows communication with
the M.U.T.-III.
Engine-ECU16Receives a signal from the active stability control
system-ECU to control the engine output.
Anti-skid Brake/Active Stability Control
System control unit (ABS/active stability
control system-ECU)17Controls actuators (described above) based on the signals
coming from each sensor.
Controls the self-diagnostics and fail-safe functions.
Controls the diagnostic function (M.U.T.-III compatible).
