VDC FUNCTION, TCS FUNCTION AND BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION

VDC warning lamp in combination meter turn ON when a malfunction occurs in system [ABS actuator and

electric unit (control unit)]. The control is suspended for VDC function, TCS function and brake limited slip dif-

ferential (BLSD) function. The vehicle status becomes the same as models without VDC function, TCS func-

tion and brake limited slip differential (BLSD) function. However, ABS function and EBD function are operated

normally.

ABS FUNCTION

ABS warning lamp and VDC warning lamp in combination meter turn ON when a malfunction occurs in system

[ABS actuator and electric unit (control unit)]. The control is suspended for VDC function, TCS function, ABS

function and brake limited slip differential (BLSD) function. The vehicle status becomes the same as models

without VDC function, TCS function, ABS function and brake limited slip differential (BLSD) function. However,

EBD function is operated normally.

NOTE:

ABS self-diagnosis sound may be heard the same as in the normal condition, because self-diagnosis is per-

formed when ignition switch turns ON and when vehicle initially starts.

EBD FUNCTION

ABS warning lamp, brake warning lamp and VDC warning lamp in combination meter turn ON when a mal-

function occurs in system [ABS actuator and electric unit (control unit)]. The control is suspended for VDC

function, TCS function, ABS function, EBD function and brake limited slip differential (BLSD) function. The

vehicle status becomes the same as models without VDC function, TCS function, ABS function, EBD function

and brake limited slip differential (BLSD) function.

• 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-

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.

TCS FUNCTION : System Description

INFOID:0000000012199665

• 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

and brake limited slip differential (BLSD) function. The vehicle sta-

tus becomes the same as models without VDC function, TCS func-

tion and brake limited slip differential (BLSD) function. However,

ABS function and EBD function are operated normally. Refer to
