EBD Function

ABS warning lamp, brake 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, EBD function, hill start assist function, brake limited slip differential (BLSD) function and trailer sway control function. The vehicle status becomes the same as models without VDC function, TCS function, ABS function, EBD function, hill start assist function, brake limited slip differential (BLSD) function and trailer sway control function.
