[VDC/TCS/ABS]
NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
Description
INFOID:0000000003247250
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 a 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 G sensor system, when the vehicle turns sharply, such as dur-
ing a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illuminated).
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.)

PRECAUTIONS
FOR USA AND CANADA
FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER"
INFOID:0000000004790234
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 AIRBAG” and “SEAT BELT” 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 AIRBAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.
FOR USA AND CANADA : Precaution for Procedure without Cowl Top Cover
INFOID:0000000004790235
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
FOR USA AND CANADA : Precaution for Brake System
INFOID:0000000003247253
WARNING:
Clean any dust from the front brake and rear brake with a vacuum dust collector. Never blow with com-
pressed air.
CAUTION:
• Only use “DOT 3” brake fluid. Refer to
MA-15, "FOR NORTH AMERICA : Fluids and Lubricants"
.
• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and
cause improper operation.
• Always loosen the brake tube flare nut with a flare nut wrench.

< PRECAUTION >
[VDC/TCS/ABS]
PRECAUTIONS
• Tighten the brake tube flare nut to the specified torque with
crowfoot (A) and torque wrench (B).
• Always confirm the specified tightening torque when install-
ing the brake pipes.
• Turn the ignition switch OFF and disconnect the ABS actuator
and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.
• Check that no brake fluid leakage is present after replacing
the parts.
FOR USA AND CANADA : Precaution for Brake Control
INFOID:0000000003247254
• When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor
operating noise may be heard from engine compartment. This is normal condition.
• 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 estimate causes before starting diagnos-
tic servicing. Besides electrical system inspection, check brake 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.
• ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in wire
near the control unit.
• If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
• VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
- When replacing the following parts with parts other than genuine parts or making modifications: Suspension-
related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-related
parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-related parts
(roll bar, tower bar, etc.).
- When driving with worn or deteriorated suspension, tires and brake-related parts.
