VDC FUNCTION, TCS FUNCTION, BRAKE LIMITED SLIP DIFFERENTIAL FUNCTION, BRAKE AS-
SIST FUNCTION, hill start assist FUNCTION AND BRAKE FORCE DISTRIBUTION FUNCTION

ESP 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 ESP function, TCS function, Brake limited slip differen-
tial (BLSD) function, Brake assist function, hill start assist function and Brake force distribution function. The
vehicle status becomes the same as models without ESP 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 normally.

ABS FUNCTION

ABS warning lamp and ESP 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 ESP function, TCS function, ABS
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 ESP function, TCS
function, ABS function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist
function and Brake force distribution 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 ESP 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 ESP
function, TCS function, ABS function, EBD 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 ESP function, TCS function, ABS function, EBD function, Brake limited slip differen-
tial (BLSD) function, Brake assist function, hill start assist function and Brake force distribution function.

Approx. 1 seconds after ignition switch is turned ON (when the 
system is in normal operation).

OFF

When VDC OFF switch is ON (VDC function, TCS function and 
Active trace control function are OFF).

VDC FUNCTION : System Description

INFOID:0000000010329790

• Side slip or tail slip may occur while driving on a slippery road or intending an urgent evasive driving. ESP/

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.

• ESP/VDC function can be switched to non-operational status (OFF) by operating ESP/VDC OFF switch. In

this case, ESP/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 

• ESP/VDC warning lamp blinks while ESP/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 ESP/VDC function, the control is suspended for

ESP/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 ESP/VDC function, TCS function, Brake limited slip differential (BLSD) function, Brake assist func-
tion, hill start assist function and Brake force distribution function. However, ABS function and EBD function
are operated normally. Refer to 

BRC-21, "Fail-Safe"
