SYSTEM DESCRIPTION
Revision: 2005 August 2006 350Z
SYSTEM DESCRIPTION PFP:00000
System Diagram NFS0002S
TCS Function NFS0002T
? The wheel spin occurrence of the drive wheels is detected by the ABS actuator and electric unit (control
unit) using the wheel speed signals from all four wheels, so when wheel spin occurs, the amount of wheel
spin is reduced by cutting the fuel to the engine, and partially closing the throttle valve to reduce the
engine torque. The throttle opening is also controlled to obtain the optimum engine torque.
? Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the opti-
mum traction has the highest priority under TCS operation.
? TCS may be activated any time the vehicle suddenly accelerates, suddenly downshifts, or is driven on a
road with a varying surface friction coefficient.
? During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.
ABS Function NFS0002U
? The Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.
? If the electrical system breaks down, then the Fail-Safe function starts, the ABS becomes inoperative,
and the ABS warning lamp turns on.
? Electrical system diagnosis by CONSULT-II is available.
EBD Function NFS0002V
? The Electronic Brake Distributor is a function that detects subtle slippages between the front and rear
wheels during braking, and it improves handling stability by electronically controlling the Brake Fluid Pres-
sure which results in reduced rear wheel slippage.
? In case of electrical system break down, the Fail-Safe function is activated, the EBD and ABS becomes
inoperative, and the ABS warning lamp and brake warning lamp are turned on.
? Electrical system diagnosis by CONSULT-II is available.
