STEP DESCRIPTION
STEP 1 Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:
WHATVehicle Model, Engine, Transmission and the System (i.e. Radio).
WHENDate, Time of Day, Weather Conditions, Frequency.
WHERERoad Conditions, Altitude and Traffic Situation.
HOWSystem Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2 Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem can not be duplicated, refer to “Incident Simulation Tests”next page.
STEP 3 Get the proper diagnoses materials together including:
POWER SUPPLY ROUTING
System Operation Descriptions
Applicable Service Manual Sections
Check for any Service Bulletin.
Identify where to begin diagnoses based upon your knowledge of the system operation and the cus-
tomer comments.
STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing
and Harness Layouts.
STEP 5 Repair or replace the incident circuit or component.
STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you
have not inadvertently created a new incident during your diagnoses or repair steps.
HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT
Work Flow
GI-22

NJGI0006
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose
problems effectively. Observe the following instructions before
diagnosing.
1)Before performing trouble diagnoses, read the “Prelimi-
nary Check”, the “Symptom Chart” or the “Work Flow”.
2)After repairs, re-check that the problem has been com-
pletely eliminated.
3)Refer to Component Parts and Harness Connector Loca-
tion for the Systems described in each section for
identification/location of components and harness con-
nectors.
4)Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness
connectors in more detail, such as when a sub-harness is
used, refer to Wiring Diagram in each individual section
and Harness Layout in EL section for identification of har-
ness connectors.
5)When checking circuit continuity, ignition switch should
be OFF.
6)Before checking voltage at connectors, check battery volt-
age.
7)After accomplishing the Diagnostic Procedures and Elec-
trical Components Inspection, make sure that all harness
connectors are reconnected as they were.

Check after engine is warmed up
sufficiently.Pin terminal check for SMJ type
ECM and TCM connectors.
For details regarding the terminal
arrangement, refer to the “ELEC-
TRICAL UNITS” electrical refer-
ence page at the end of the
manual.
Voltage should be measured with a
voltmeter.
Circuit resistance should be mea-
sured with an ohmmeter.
Current should be measured with an
ammeter.

General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers dothem for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station,
including the spare, and adjust to the specified pressure if necessary. Check
carefully for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate
properly. Also ensure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BT-7
BT-16
Tire rotationTires should be rotated every 10,000 km (6,000 miles). SU-7
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps,
and other lamps are all operating properly and installed securely. Also check
headlamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating prop-
erly.—
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play,
hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage.RS-4
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold. LC-18, LC-43
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off
the engine.LC-8, LC-30
Brake and clutch
fluid levelsMake sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.BR-7
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines.—
