[TCS/ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS0002M
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Battery ServiceNFS0002N
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Brake SystemNFS0002O

Recommended fluid is brake fluid “DOT 3”. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use a flare nut wrench when removing flare nuts, and use a flare
nut crowfoot and torque wrench when tighten brake tube flare
nuts.

When installing brake tubes, be sure to check torque.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.

Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
the battery negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions for Brake ControlNFS0002P

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting

diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level, and
oil leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

SYSTEM DESCRIPTION
Revision: 2006 November2007 350Z
SYSTEM DESCRIPTIONPFP:00000
System DiagramNFS0002S
TCS FunctionNFS0002T

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 FunctionNFS0002U

The Anti-Lock Braking 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-III is available.
EBD FunctionNFS0002V

The Electronic Brake Distribution 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-III is available.

Self-diagnosisNFS000HG
OPERATION PROCEDURE
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately
1 minute as the final inspection, and make sure that the ABS warning lamp, TCS OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.

When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
TCS OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the
system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approxi-
mately 1 minute.

Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake
fluid level switch operation (when brake fluid is insufficient).

Basic InspectionNFS00037
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.
2. Check brake tubes or hoses and around ABS actuator and electric unit (control unit) for leaks. If there is
leaking or oozing fluid, check the following items.

If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and re-conduct the leak inspection to make sure there are no leaks.

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leaks.

When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if the fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for
leaks. If fluid is still oozing out, replace the damaged part.

When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if the fluid is just
oozing out, use a clean cloth to wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out,
replace the ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake pad degree of wear. Refer to BR-26, "
PAD WEAR INSPECTION" in “Front Disc Brake” and
