System Description
INFOID:0000000010049022
• Vehicle dynamic control system detects driver's steering operation amount from the steering angle sensor.
Using input information from the yaw rate/side/decel G sensor and wheel speed sensors, the VDC system
judges driving conditions (conditions of understeer and oversteer) and controls engine output and brake
application to improve vehicle driving stability.
• During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
• Electrical system diagnosis by CONSULT is available.

System Description
INFOID:0000000010049026
• Traction Control System is a function that electronically controls engine torque and brake fluid pressure to
ensure the optimum slippage ratio at drive wheels by computing wheel speed signals from 4 wheel sensors.
When ABS actuator and electric unit (control unit) detects a spin at drive wheels, it compares wheel speed
signals from all 4 wheels. At this time, LH and RH front brake fluid pressure are controlled, while fuel being
cut to engine and throttle valve being closed to reduce engine torque by the control unit. Further more, throt-
tle position is continuously controlled to ensure the optimum engine torque at all times.
• During TCS operation, it informs driver of system operation by flashing slip indicator lamp.
• Electrical system diagnosis by CONSULT is available.
