VDC FUNCTION
VDC FUNCTION : System Description
INFOID:0000000012199664
• 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. 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 driv-

The following functions are sus-
pended.

ing conditions (conditions of understeer or oversteer) 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 and brake limited slip differential (BLSD) function. The vehicle status becomes the
same as models without VDC function, TCS function and brake limited slip differential (BLSD) function.
However, ABS function and EBD function are operated normally. Refer to
NOTE:
VDC has the characteristic as described here, This is not the device that helps reckless driving.

NOTE:
• TCM is CVT models only.
• AWD control module is AWD models only.
INPUT SIGNAL AND OUTPUT SIGNAL
Major signal transmission between each unit via communication lines is shown in the following table.

*1: Communication line between yaw rate/side/decel G sensor and ABS actuator and electric unit (control unit)
*2: Models with CVT
*3: AWD models
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. Moment directing towards the outer side of turn is generated. Oversteer is prevented.
