SIST FUNCTION, hill start assist FUNCTION AND BRAKE FORCE DISTRIBUTION 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, Brake limited slip differ-
ential (BLSD) function, Brake assist function, hill start assist function and Brake force distribution function. The
vehicle status becomes the same as models without VDC 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 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, 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 VDC 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 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
