PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612923
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001327654
 Recommended fluid is brake fluid “DOT 3”. Refer to MA-9.
 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 safe ty 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 electrical
connectors of ABS actuator and elec tric unit (control unit) or bat-
tery 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.
Precaution for Brake ControlINFOID:0000000001327655
 During VDC/TCS/ABS operation, brake pedal lightly vi brates 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 customer
(what symptoms are present under what conditions) and check for simple causes before starting diagnostic
servicing. Besides electrical system inspection, c heck booster operation, brake fluid level, and fluid leaks.
 If tire size and type are used in an improper combinat ion, 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, VDC/TCS/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
SchematicINFOID:0000000001327660
FunctionsINFOID:0000000001327661
VDC
 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 steering /
over steering) is determined from information from G s ensor, 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 subject
to strong shaking or large vibration, such as when vehi cle 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
 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 pressure con-
trol and engine fuel cut are performed while throttle value is restricted to reduce the engi\
ne 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 sy stem operation by flashing SLIP indicator lamp.
ABS
 The Anti-Lock Braking System is a function that detec ts wheel revolution while braking, and it improves han-
dling stability during sudden braking by electrically prev enting 4 wheel lock. Maneuverability is also improved
for avoiding obstacles.
 If the electrical system malfunc tions, then the fail-safe function star ts, the ABS becomes inoperative, and
ABS warning lamp turns on.
 Electrical system diagnosis by CONSULT-III 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
 The Electronic Brake Distribution is a function that detects subtle slippages between front and rear wheels
during braking, and it improves handling stability by elec tronically 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 inopera-
tive, and ABS warning lamp and brake warning lamp are turned on.
 Electrical system diagnosis by CONSULT-III 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 FunctionINFOID:0000000001327662
VDC / TCS SYSTEM
In case of malfunction in the VDC/TCS system, VDC O FF indicator lamp and SLIP indicator lamp are turned
on, and the condition of vehicle is the same as the c ondition of vehicles without VDC/TCS system. In case of
malfunction in the VDC/TCS system, the ABS control c ontinues to operate normally without VDC/TCS control.
CAUTION:
If the fail-safe function is acti vated, then perform the self-diagnos is 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 malfunc tions with the EBD, brake warning lamp, ABS warning lamp,
VDC OFF indicator lamp and SLIP indicator lamp wil l turn on. Simultaneously, the VDC/TCS/ABS become one
of the following conditions of the fail-safe function.
 For malfunction of ABS, only the EBD is activated and t he condition of vehicle is the same condition of vehi-
cles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a no rmal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
 For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles wit hout TCS/ABS, EBD system.

PRECAUTIONS FOR DIAGNOSIS
 Before performing diagnosis, always read precautions. Refer to BRC-13, "How to Proceed with Diagnosis".
 If ABS actuator and electric unit (control unit), steer ing angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-8, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion".
 After diagnosis is finished, be sure to erase memory. Refer to BRC-26, "
Self-Diagnosis".
 When checking continuity and voltage between units, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfuncti on is found, repair or replace connector terminals.
 For intermittent symptoms, possible cause is malfunc tion in harness, harness connector, or terminals. Move
harness, harness connector, and terminals to check for poor connections.
 If a circuit tester is used for the check, be ca reful not to forcibly extend any connector terminal.
 To use CONSULT-III to perform self-diagnosis of ABS act uator and electric unit (control unit), active tests, or
work support, first stop work, then connect CONSULT-III and select “ABS”.
 While self-diagnostic results of CONSULT-III shows malf unction, if CONSULT-III active test is performed, an
engine system error may be indicated. In this case, start engine to resume the normal screen.
 VDC/TCS/ABS system electronica lly controls brake operation and engine output. The following symptoms
