Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AFS00289
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 Brake SystemAFS001S3

Recommended fluid is brake fluid “DOT 3”.

Do not 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.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut crowfoot and torque wrench, securely tighten
brake tube flare nuts.

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 connectors of ABS actuator and electric unit (control unit) or
battery negative terminal.

When installing brake piping, be sure to check torque.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlAFS001S4

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

Just after starting vehicle after turning ignition switch ON, brake pedal may vibrate or motor operating
noise may be heard from engine room. 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
fluid 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.

SYSTEM DESCRIPTION
Revision: 2005 July 2005 FX
SYSTEM DESCRIPTIONPFP:00000
System DiagramAFS001SB
VDC FunctionAFS001SC

In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected
from steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under steer-
ing / over steering) is determined from information from 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.

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

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

ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when vehicle is sub-
ject to strong shaking or large vibration, such as when vehicle is on a turn table, a ship or a steep slope
such as bank while engine is running. In this case, restart engine on a normal road, and if ABS warning
lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off, there is no malfunction.
TCS FunctionAFS001SD

The wheel spin of the drive wheels is detected by ABS actuator and electric unit (control unit) from the
wheel speed signals from four wheels, so if wheel spin occurs, drive wheel right and left brake fluid pres-
sure control and engine fuel cut are performed while throttle value is restricted to reduce the engine
torque and decrease the amount of wheel spin. In addition, the degree 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 vehicle suddenly accelerates, suddenly down/upshifts, 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 FunctionAFS001SE

The anti-lock brake system is a function that detects wheel revolution while braking, and it improves han-
dling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.

If the electrical system malfunctions, then the fail-safe function starts, the ABS becomes inoperative, and
ABS warning lamp turns on.

Electrical system diagnosis by CONSULT-II is available.

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

When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noises
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.
EBD FunctionAFS001SF

Electronic brake distributor is a function that detects subtle slippages between front and rear wheels dur-
ing braking, and it improves handling stability by electronically controlling the brake fluid pressure which
results in reduced rear wheel slippage.

In case of electrical system malfunction, the fail-safe function is activated, EBD and ABS becomes inoper-
ative, and ABS warning lamp and brake warning lamp are turned on.

Electrical system diagnosis by CONSULT-II is available.

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

When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noises
may be heard from engine compartment. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionAFS001SG
VDC / TCS SYSTEM
In case of malfunction in the VDC/TCS system, VDC OFF indicator lamp and SLIP indicator lamp are turned
on, and the condition of vehicle is the same as the condition of vehicles without VDC/TCS system. In case of
malfunction in the VDC/TCS system, the ABS control continues to operate normally without VDC/TCS control.
CAUTION:
If the fail-safe function is activated, then perform the self-diagnosis for VDC/TCS/ABS control system.
ABS, EBD SYSTEM
In case of electrical malfunctions with the ABS, ABS warning lamp, VDC OFF indicator lamp and SLIP indica-
tor lamp will turn on. In case of electrical malfunctions with the EBD, brake warning lamp, ABS warning lamp,
VDC OFF indicator lamp and SLIP indicator lamp will turn on. Simultaneously, the VDC/TCS/ABS become one
of the following conditions of the fail-safe function.
1. For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehicles without TCS/ABS system.
2. For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the condition of vehicles without TCS/ABS, EBD system.
NOTE:
In condition 1 described above, an ABS self-diagnosis sound may be heard. That is a normal condition
because a self-diagnosis for “Ignition switch ON” and “The first starting” are being performed.
