VDC FUNCTION
VDC FUNCTION : System Description
INFOID:0000000011280571
• Side slip or tail slip may occur while driving on a slippery road or intending an urgent evasive driving. VDC
function detects side slip status using each sensor when side slip or tail slip is about to occur and improves
vehicle stability by brake control and engine output control during driving.
• In addition to ABS function, EBD function and TCS function, target side slip amount is calculated according
to steering operation amount from steering angle sensor and brake operation amount from brake pressure
sensor. By comparing this information with vehicle side slip amount that is calculated from information from
yaw rate/side/decel G sensor and wheel sensor, vehicle driving conditions (conditions of understeer or over-

steer) are judged and vehicle stability is improved by brake force control on all 4 wheels and engine output
control.
• VDC function can be switched to non-operational status (OFF) by operating VDC OFF switch. In this case,
VDC OFF indicator lamp turns ON.
• Control unit portion automatically improves driving stability by performing brake force control as well as
engine output control, by transmitting drive signal to actuator portion according to difference between target
side slip amount and vehicle side slip amount
• VDC warning lamp blinks while VDC function is in operation and indicates to the driver that the function is in
operation.
• CONSULT can be used to diagnose the system diagnosis.
• Fail-safe function is adopted. When a malfunction occurs in VDC function, the control is suspended for VDC
function, TCS function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist
function and Brake force distribution function. The vehicle status becomes the same as models without VDC
function, TCS function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist
function and Brake force distribution function. However, ABS function and EBD function are operated nor-
mally. Refer to

OPERATION CHARACTERISTICS
VDC Function That Prevents Oversteer Tendency
• During a cornering, brake force (brake fluid pressure) is applied on front wheel and rear wheel on the outer
side of turn. Momentum directing towards the outer side of turn is generated. Oversteer is prevented.
• Changing driving lane on a slippery road, when oversteer tendency is judged large, engine output is con-
trolled as well as brake force (brake fluid pressure) of 4 wheels. Oversteer tendency decreases.

SYSTEM
• During a cornering, brake force (brake fluid pressure) is applied on front wheel and rear wheel on the inner
side of turn. Momentum directing towards the inner side of turn is generated. Understeer is prevented.
• Applying braking during a cornering on a slippery road, when understeer tendency is judged large, engine
output is controlled as well as brake force (brake fluid pressure) of four wheels. Understeer tendency
decreases.
TCS FUNCTION
TCS FUNCTION : System Description
INFOID:0000000011280572
• Wheel spin status of drive wheel is detected by wheel sensor of 4
wheels. Engine output and transmission shift status is controlled
so that slip rate of drive wheels is in appropriate level. When wheel
spin occurs on drive wheel, ABS actuator and electric unit (control
unit) perform brake force control of LH and RH drive wheels (apply
brake force by increasing brake fluid pressure of drive wheel) and
decrease engine torque by engine torque control. Wheel spin
amount decreases. Engine torque is controlled to appropriate
level.
• TCS function can be switched to non-operational status (OFF) by
operating VDC OFF switch. In this case, VDC OFF indicator lamp
turns ON.
• VDC warning lamp blinks while TCS function is in operation and
indicates to the driver that the function is in operation.
• CONSULT can be used to diagnose the system diagnosis.
• Fail-safe function is adopted. When a malfunction occurs in TCS
function, the control is suspended for VDC function, TCS function,
Brake limited slip differential (BLSD) function, Brake assist func-
tion, hill start assist function and Brake force distribution function
The vehicle status becomes the same as models without VDC
function, TCS function, Brake limited slip differential (BLSD) func-
tion, Brake assist function, hill start assist function and Brake force
distribution function However, ABS function and EBD function are
operated normally. Refer to
