< SYMPTOM DIAGNOSIS >[ESP/TCS/ABS]
NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
DescriptionINFOID:0000000001731207
Symptom Result
Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is acti-
vated.
This is a normal condi-
tion due to the VDC,
TCS or ABS activation. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
The brake pedal moves and generates noises, when TCS or VDC is activated due to rapid acceleration or
sharp turn.
The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and
just after the vehicle starts.This is normal, and it is
caused by the ABS op-
eration check.
Depending on the road conditions, the driver may experience a sluggish feel. This is normal, because
TCS places the highest
priority on the optimum
traction (stability). TCS may activate momentarily if wheel speed changes when driving over location where friction coefficient
varies, when downshifting, or when fully depressing accelerator pedal.
The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn ON when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is rotating on a turntable or located on
a ship while the engine is running. In this case, restart the
engine on a normal
road. If the normal con-
dition is restored, there
is no malfunction. At
that time, erase the self-
diagnosis memory. VDC may not operate normally or the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp
may illuminate, when running on a special road that is extremely slanted (e.g. bank in a circuit course).
A malfunction may occur in the yaw rate/side/decel G sensor system, when the vehicle turns sharply, such
as during a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illumi-
nated).
The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the
speedometer on a 2-wheel chassis dynamometer. Normal (Deactivate the
VDC/TCS function be-
fore performing an in-
spection on a chassis
dynamometer.)
VDC OFF indicator lamp and SLIP indicator lamp may simultaneously turn on when low tire pressure warn-
ing lamp turns on.This is not a VDC sys-
tem error but results
from characteristic
change of tire.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001691411
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
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 har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001691412
 Recommended fluid is Genuine NISSAN Fluid, DOT 3 or DOT 4 (US FMVSS No. 116).
 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 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 electrical
connectors of ABS actuator and electric unit (control unit) or bat-
tery negative terminals.
 When installing brake piping, be sure to check torque.
 After removing/installing any hydraulic parts of the brake or ESP
system (such as actuator and piping parts, etc), bleed air from the
system.
Precaution for Brake ControlINFOID:0000000001691413
 During ESP/TCS/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 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 the cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting diag-
nostic servicing. Besides the 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.
 If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ESP/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.

PRECAUTIONS
 If the following components are replaced with non-genuine components or converted, ESP OFF indicator
lamp and SLIP indicator lamp may turn on or the ESP system may not operate properly. Components
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 suspension, tires or components related to the
brakes may cause ESP OFF indicator lamp and SLIP indicator lamp turn on, and the ESP system may not
operate properly.
 When the TCS or ESP is activated by sudden acceleration or sudden turn, some noise may occur. The noise
is a result of the normal operation of the TCS and ESP.
 When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the ESP may not operate normally, or ESP warning lamp and SLIP indicator
lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restarting
engine.
 Sudden turns (such as spin turns, acceleration turns), drifting, etc. When ESP function is OFF (ESP SW ON)
may cause the G -sensor system indicate a malfunction. However, this is not a malfunction, if normal opera-
tion can be resumed after restarting engine.

INFOID:0000000001375288
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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
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
