TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
System operation check noiseWhen the engine is started, you may barely be able to hear a slight thudding
sound from the engine room, but this sound is made by the system operation
check and is normal.Normal
TCS operation
(SLIP indicator lamp ON)TCS may be activated any time the vehicle suddenly accelerates, suddenly
downshifts, or is driven on a road with a varying surface friction coefficient.
Normal
When conducting the
inspection on a chas-
sis dynamometer,
cancel the TCS func-
tion. When inspecting the speedometer, etc., press TCS OFF switch to turn off
TCS function before conducting the work.
When accelerator pedal is depressed on a chassis dynamometer (front
wheel fixing type), the vehicle speed will not increase. This is normal,
because TCS is activated by the stationary front wheels. The warning lamp
may also turn on to show “sensor system error” in this case. This is not a
malfunction either, because the stationary front wheels are detected. Restart
engine, and drive the vehicle at 30 km/h (19 MPH) or more or higher to
check that the warning lamp no longer turns on.
ABS operation
(longer stopping distance)Stopping distance may be longer for vehicles with ABS when the vehicle
drives on rough or snow-covered roads. Use lower speeds when driving on
these kinds of roads.Normal
Sluggish feelDepending on road circumstances, the driver may have a sluggish feel. This
is normal, because under TCS operation optimum traction has the highest
priority (safety first). Sometimes the driver has a slight sluggish feel in
response to substantial accelerator pedal operation.Normal Symptom Symptom description Result

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
BR-39, "

PRECAUTIONS
Revision: 2006 November2007 350Z
[VDC/TCS/ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000TP
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 ServiceNFS0003R
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 SystemNFS0003S

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 VDC/TCS/ABS control unit or the battery nega-
tive terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

Precautions for Brake ControlNFS0003T

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.

If the following components are replaced with non-genuine components or converted, the VDC OFF indi-
cator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Compo-
nents related to suspension (Shock Absorber, Strut, Spring, Bush, etc.), Tires, wheels (exclude specified
size), components related to brake (Pad, Rotor, Caliper, etc.), Components related to engine (Muffler,
ECM, etc.), Components related to body reinforcement (Roll bar, Tower bar, etc.).

Driving in the condition of breakage or excessive wear of the suspension, tires or components related to
the brakes may cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC
system may not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur if the
brake pedal is used. The noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or the VDC warning lamp may turn on.
However, this is not a problem if normal operation can be resumed after restarting the engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC SW
ON) may cause the yaw rate/side G -sensor system indicate a problem. However this is not a problem if
normal operation can be resumed after restarting the engine.

SYSTEM DESCRIPTIONPFP:00000
System DiagramNFS0003X
VDC FunctionNFS0003Y

In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected
from the steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under-
steering / over-steering) is determined from information from the yaw rate/side G sensor, wheel sensor,
etc., and this information is used to improve vehicle stability by controlling the braking and engine power
to all four wheels.

The SLIP indicator lamp flashes to inform the driver of VDC operation.

During VDC operation, the body and brake pedal lightly vibrate and mechanical noises may be heard.
This is normal.

The ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when the vehicle
is subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while
the engine is running. In this case, restart the engine on a normal road, and if the ABS warning lamp, VDC
OFF indicator lamp, and SLIP indicator lamp turn off, there is no problem.
TCS FunctionNFS0003Z

The wheel spin of the drive wheels is detected by the VDC/TCS/ABS control unit from the wheel speed
signals from the four wheels, so if wheel spin occurs, the rear wheel right and left brake fluid pressure
control and engine fuel cut are conducted while the throttle value is restricted to reduce the engine torque
and decrease the amount of wheel spin. In addition, the degree the throttle is opened is controlled to
achieve 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.
