PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000RO
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 Procedures without Cowl Top CoverNFS000RP
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000RQ

Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.

Recommended fluid is brake fluid “DOT 3”. Refer to MA-12, "Fluids and Lubricants" .

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.

Use clean brake fluid, to clean or wash all parts of master cylinder and disc brake caliper, etc.

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use flare nut torque wrench when installing brake tube.

When installing brake tube and hose, be sure to check torque.

Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.

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 BR-27, "
BRAKE BURNISHING PROCE-
DURE" (front disc brake), BR-33, "BRAKE BURNISHING PRO-
CEDURE" (rear disc brake).
WARNING:

Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

Precautions for Brake ControlNFS000Q1

Just after starting vehicle after ignition switch ON, 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 cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic 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: Suspen-
sion-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.

TROUBLE DIAGNOSIS
Revision: 2007 April2007 M35/M45
TROUBLE DIAGNOSISPFP:00004
Fail-Safe FunctionNFS000Q8
ABS, EBD SYSTEM
In the event there is a malfunction with the electrical system, the ABS warning lamp, VDC OFF indicator lamp,
and SLIP indicator lamp will turn on when it is the ABS that is malfunctioning, and the brake warning lamp,
ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp will turn on when it is the EBD that is
malfunctioning. At the same time, the VDC/TCS/ABS will be put in one of the following states by the fail-safe
function.

When the ABS malfunctions, only the EBD operates. The condition is the same as that of models without
VDC/TCS/ABS.
NOTE:
ABS self-diagnosis sound may be heard. This is normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.

When the EBD malfunctions, the EBD and ABS will not operate. The condition is the same as that of mod-
els without VDC/TCS/ABS and EBD.
VDC/TCS
In case of VDC/TCS system malfunction, the VDC OFF indicator lamp and SLIP indicator lamp or only VDC
OFF indicator lamp are turned on, and the condition of the vehicle is the same as the condition of vehicles
without VDC/TCS equipment. In case of electrical malfunction with the VDC/TCS system, the ABS control
continues to operate normally even though VDC/TCS does not operate.
CAUTION:
If the Fail-Safe function is activated, then perform self-diagnosis for VDC/TCS/ABS control system.
How to Perform Trouble DiagnosesNFS000QB
BASIC CONCEPT

The most important point to perform trouble diagnosis is to understand systems (control and mechanism)
in vehicle thoroughly.

It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptom, and understand it fully.
Ask customer about his/her complaints carefully. In some cases,
they will be necessary to check symptom by driving vehicle with
customer.
CAUTION:
Customers are not professionals. Do not assume “maybe
customer means...” or “maybe customer mentioned this
symptom”.

It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptom based on interview with customer and past examples.
Do not perform inspection on ad hoc basis. Most intermittent
malfunctions are caused by poor contacts. In this case, it will be
effective to shake suspected harness or connector by hand.
When repairs are performed without any symptom check, no
one can judge if malfunction has actually been eliminated.

After diagnostic, make sure to perform “ERASE MEMORY”.
Refer to BRC-24, "
ERASE MEMORY" .

Always read “GI General Information” to confirm general precau-
tions. Refer to GI-4, "
General Precautions" .
