VDC (ESP) FUNCTION
VDC (ESP) FUNCTION : System Description
INFOID:0000000010723634
• 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 TCS function, ABS function and EBD function, target side slip amount is calculated according
to steering operation amount from steering angle sensor and brake operation amount from pressure sensor.
By comparing this information with vehicle side slip amount that is calculated from information from yaw rate/
side G sensor and wheel sensor, vehicle driving 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, brake limited slip differential (BLSD) function, brake assist function, brake force dis-
tribution function, hill start assist function, advanced hill descent control function (4WD models with gasoline
engine), active trace control function (control of chassis control module) and active ride control function (con-
trol of chassis control module). The vehicle status becomes the same as models without VDC function, TCS
function, brake limited slip differential (BLSD) function, brake assist function, brake force distribution func-
tion, hill start assist function, advanced hill descent control function (4WD models with gasoline engine),
active trace control function (control of chassis control module) and active ride control function (control of
chassis control module). 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:
• 4WD control unit is applied to 4WD models.
• TCM is applied to CVT models.
