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.
