• Vehicle Dynamics Control system detects driver

′

s steering operation amount and brake pedal travel from

steering angle sensor and pressure sensors. Using information from yaw rate/side/decel G sensor and

wheel sensor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle

driving stability by controlling brake application to 4 wheels and engine output.

• During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.

• Electrical system diagnosis by CONSULT is available.

System Description

INFOID:0000000007356831

• Traction Control System is a function that electronically controls engine torque, brake fluid pressure and A/T

gear position 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 (rear

wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid pres-

sure are controlled, while fuel being cut to engine and throttle valve being closed to reduce engine torque by

the control unit. Further more, throttle 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.
