CONDITIONS FOR TURNING ON THE INDICATOR LAMP
VDC OFF indicator lamp
• Turns ON when VDC function and TCS function are switched to non-operational status (OFF) by VDC OFF
switch.
• Turns ON when ignition switch turns ON and turns OFF when the system is normal for bulb check purposes.
Fail-Safe
INFOID:0000000009177246
VDC FUNCTION, TCS FUNCTION and hill start assist FUNCTION
VDC warning lamp in combination meter turns ON when a malfunction occurs in system [ABS actuator and
electric unit (control unit)]. The control is suspended for VDC function, TCS function and hill start assist func-
tion. The vehicle status becomes the same as models without VDC function, TCS function and hill start assist
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 hill start assist function. The vehicle status becomes the same as models without VDC function,
TCS function, ABS function and hill start assist 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 hill start assist function. The vehicle status becomes
the same as models without VDC function, TCS function, ABS function, EBD function and hill start assist func-
tion.

VDC FUNCTION : System Description
INFOID:0000000009177248
• Side slip or tail slip may occur while driving on a slippery road or during intended 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.
• VDC function has brake limited slip differential (BLSD) function. LH and RH driving wheel spin is always
monitored. If necessary, appropriate brake force is independently applied to LH or RH driving wheel so that
one-sided wheel spin is avoided and traction is maintained. Mainly starting ability is improved. [Brake limited
slip differential (BLSD) function operates while VDC function is in non-operational status (OFF) by VDC OFF
