PRECAUTIONS

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS00662
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
Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake System
EFS00663
CAUTION:
●
Refer to
MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS"
for recommended brake fluid.
●
Never reuse drained brake fluid.
●
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
●
To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
●
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.
●
Use flare nut wrench when removing and installing brake
tube.
●
If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
●
Turn the ignition switch OFF and remove the connector of
the ABS actuator and electric unit (control unit) or the bat-
tery terminal before performing the work.
●
Always torque brake lines when installing.
●
Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to
(front disc brake) or
(rear disc
brake).
WARNING:
●
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions When Using CONSULT-II
EFS00664
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1.
Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
●
If YES, GO TO 2.

●
If NO, GO TO 5.
2.
Is there any indication other than indications relating to CAN communication system in the self-diagnosis
results?
●
If YES, GO TO 3.
●
If NO, GO TO 4.
3.
Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4.
Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefor, erase the self-diagnosis results.
5.
Diagnose CAN communication system. Refer to
Precautions for Brake Control
EFS00665
●
During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
●
During HDC operation, a mechanical noise may be heard. This is normal.
●
Just after starting vehicle, the brake pedal may vibrate or a 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
diagnosis. Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid
leaks.
●
If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
●
If there is a radio, antenna or related 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 or improper wiring.
●
If the following components are replaced with non-genuine components or modified, the VDC OFF indica-
tor lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorbers, struts, springs, bushings, etc.), tires, wheels (exclude specified
size), components related to brake system (pads, rotors, calipers, etc.), components related to engine
(muffler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).
●
Driving with broken or excessively worn suspension components, tires or brake system components 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. 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 curves on a freeway), the VDC may not operate normally, or the VDC warning lamp and the SLIP
indicator lamp may turn on. 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. with VDC turned off may cause the yaw
rate/side G sensor to indicate a problem. This is not a problem if normal operation can be resumed after
restarting the engine.
●
If battery is removed or steering angle sensor is disconnected, power to steering angle sensor is lost and
the screen goes into steering angle sensor safe mode.
●
When screen goes into steering angle sensor safe mode, perform "Adjustment of Steering Angle Sensor
Neutral Position" with CONSULT-II and check that VDC OFF indicator turns off. Additionally, perform self-
diagnosis, check that only "Steering Angle Sensor Safe Mode" is shown for self-diagnostic result, and
then delete the memory. (If the self-diagnostic result shows an indication other than "Steering Angle Sen-
sor Safe Mode", repair the relevant part and restart self-diagnosis.) The steering angle sensor is released
and returns to normal condition by performing the above operation.
●
When checking, if only "Steering Angle Sensor Safe Mode" is shown in the self-diagnostic result and VDC
OFF indicator is off, delete history of malfunction. This happens when battery power supply is lost and the
screen goes into Steering Angle Sensor Safe Mode, and then screen returns to normal mode automati-

cally by driving the vehicle in a straight forward direction [for approximately 30 seconds at 20 km/h (12
MPH) or more] after power is supplied again.
NOTE:
VDC OFF indicator lamp is on when VDC OFF switch is on.
Precautions for CAN System
EFS00666
●
Do not apply voltage of 7.0V or higher to terminal to be measured.
●
Maximum open terminal voltage of tester in use must be less than 7.0V.
●
Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.
●
Area to be repaired must be soldered and wrapped with tape.
Make sure that fraying of twisted wire is within 110 mm (4.33 in).
●
Do not make a bypass connection to repaired area. (If the circuit
is bypassed, characteristics of twisted wire will be lost.)
