Fail-Safe

VDC FUNCTION, TCS FUNCTION, BRAKE ASSIST 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, brake assist function and hill start assist function. The Nissan Murano vehicle status becomes the same as models without VDC function, TCS function, brake assist function and hill start assist function. However, ABS function and EBD function operate 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 assist function and hill start assist function. The Nissan Murano vehicle status becomes the same as models without VDC function, TCS function, ABS function, brake assist function and hill start assist function. However, EBD function operates normally.

NOTE:

ABS self-diagnosis sound may be heard the same as in the normal condition, because self-diagnosis is performed when ignition switch ON and when Nissan Murano vehicle initially starts.

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, brake assist function and hill start assist function. The Nissan Murano vehicle status becomes the same as models without VDC function, TCS function, ABS function, EBD function, brake assist function and hill start assist function.
