System Description
INFOID:0000000007544625
• In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected by
the steering angle sensor and pressure sensor, and the vehicle
′
s driving status (amount of under steering/
over steering) is determined by the information from the yaw rate/side/decel G sensor, wheel sensor, etc.,
and this information is used to improve vehicle stability by controlling the braking and engine power to all
four wheels.
• During VDC operation, it informs driver of system operation by blinking the VDC warning lamp.
• Electrical system diagnosis by CONSULT is available.

System Description

• The wheel spin of the drive wheels is detected by the ABS actuator and electric unit (control unit) using the
wheel speed signals from the four wheels, so if wheel spin occurs, the drive wheel right and left brake fluid
pressure control and engine fuel cut are conducted while the throttle valve opening is restricted to reduce the
engine torque and decrease the amount of wheel spin. In addition, the throttle opening is controlled to
achieve the optimum engine torque.
• During TCS operation, TCS informs driver of system operation by blinking the VDC warning lamp.
• Electrical system diagnosis by CONSULT is available.
