Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL P11 is as follows (The
composition varies according to the destination and optional equipment.):
lFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the
steering wheel), front passenger air bag module (located on the instrument panel on passenger side),
front seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
lFor a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a
frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
lTo 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 should be per-
formed by an authorized NISSAN dealer.
lImproper 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 RS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for Brake System
lRecommended fluid is brake fluid ªDOT 4º.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.
lTo clean or wash all parts of master cylinder, disc brake
caliper and wheel cylinder, use clean brake fluid.
lNever use mineral oils such as gasoline or kerosene.
They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing and installing brake
tube.
lAlways torque brake lines when installing.
lBurnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to ªBrake Burnishing Procedureº, ªCheck and
Adjustmentº, BR-7.
WARNING:
lClean brake pads with a waste cloth, then wipe with a
dust collector.

WARNING:
Clean brake pads with a vacuum dust collector to minimize
the hazard of airborne particles or other materials.
CAUTION:
lWhen cylinder body is open, do not depress brake pedal
because piston will pop out.
lBe careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.
lIf shims are rusted or show peeling of rubber coat,
replace them with new shims.

3. Disassemble cylinder body.
a. Pry off snap ring B with suitable pliers, then remove spring
cover, spring and retaining washer.
b. Remove key plate, push rod, O-ring and strut.
c. Remove piston seal.
Be careful not to damage cylinder body.
4. Remove return spring, toggle lever and cable guide.
Inspection
Caliper
CAUTION:
Use brake fluid to clean cylinder. Never use mineral oil.
Cylinder Body
lCheck inside surface of cylinder for score, rust, wear, dam-
age or presence of foreign materials. If any of the above
conditions are observed, replace cylinder body.
lMinor damage from rust or foreign materials may be elimi-
nated by polishing surface with a fine emery paper.
Replace cylinder body if necessary.
Torque Member
Check for wear, cracks or other damage. Replace if necessary.
Piston
CAUTION:
Piston sliding surface is plated. Do not polish with emery
paper even if rust or foreign matter is stuck to sliding sur-
face.
Check piston for score, rust, wear, damage or presence of for-
eign materials.
Replace if any of the above conditions are observed.

Engine Fuel & Emission Control System
NEF390 ECM (ECCS-D control module)
lDo not disassemble ECM.lIf a battery terminal is disconnected, the memory
will return to the ECM value.
The ECM will now start to self-control at its initial
value. Engine operation can vary slightly when
the terminal is disconnected. However, this is not
an indication of a problem. Do not replace parts
because of a slight variation.
lWhen ECM is removed for inspection, make sure
to ground the ECM mainframe.WIRELESS EQUIPMENT
lWhen installing C.B. ham radio or a mobile
phone, be sure to observe the following as it
may adversely affect electronic control sys-
tems depending on its installation location.
1) Keep the antenna as far as possible away
from the ECM.
2) Keep the antenna feeder line more than
20 cm (7.9 in) away from the harness of elec-
tronic controls.
Do not let them run parallel for a long dis-
tance.
3) Adjust the antenna and feeder line so that the
standing-wave ratio can be kept small.
4) Be sure to ground the radio to vehicle body.
ECM HARNESS HANDLING
lConnect ECM harness connectors securely.
A poor connection can cause an extremely
high (surge) voltage to develop in coil and
condenser, thus resulting in damage to ICs.
lKeep ECM harness at least 10 cm (3.9 in)
away from adjacent harnesses, to prevent an
ECM system malfunction due to receiving
external noise, degraded operation of ICs,
etc.
lKeep ECM parts and harnesses dry.lBefore removing parts, turn off ignition
switch and then disconnect battery ground
cable. WHEN STARTING
lDo not depress accelerator pedal when
starting.
lImmediately after starting, do not rev up
engine unnecessarily.
lDo not rev up engine just prior to shut-
down. ECM PARTS HANDLING
lHandle mass air flow sensor carefully to avoid
damage.
lDo not disassemble mass air flow sensor.lDo not clean mass air flow sensor with any type
of detergent.
lDo not disassemble No. 1 injection nozzle (built-
in needle lift sensor).
lEven a slight leak in the air intake system can
cause serious problems.
lDo not shock or jar the camshaft position sensor
(TDC). ELECTRONIC FUEL INJECTOR PUMP
lDo not disconnect pump harness connectors
with engine running.
lDo not disassemble or adjust electronic fuel
injection pump, except for the following
parts.
Camshaft position sensor (pump)
Injection timing control valve
Fuel cut solenoid valve BATTERY
lAlways use a 12 volt battery as power
source.
lDo not attempt to disconnect battery cables
while engine is running.
