TROUBLE DIAGNOSIS
Trouble Diagnosis IntroductionINFOID:0000000006341730
INTRODUCTION
The engine has an ECM to control major systems such as fuel con-
trol, ignition control, idle air control system, etc. The ECM accepts
input signals from sensors and instantly
drives actuators. It is essen-
tial that both input and output signals are proper and stable. At the
same time, it is important that there are no malfunctions such as vac-
uum leaks, fouled spark plugs, or other malfunctions with the engine.
It is much more difficult to diagnose an incident that occurs intermit-
tently rather than continuously. Most intermittent incidents are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only may not find t he cause of the incidents. A road
test with CONSULT-III (or GST) or a circuit tester connected should
be performed. Follow the Work Flow on "WORK FLOW".
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driv ability complaint. The customer
can supply good information about such incidents, especially inter-
mittent ones. Find out what symptoms are present and under what
conditions they occur. A Diagnosti c Worksheet like the example on
"Worksheet Sample" should be used.
Start your diagnosis by looking for conventional malfunctions first.
This will help troubleshoot drivability malfunctions on an electroni-
cally controlled engine vehicle.

PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000005931131
Two different maintenance schedules are provi ded, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage/time intervals.

Schedule 1Follow Periodic Maintenance Schedule 1 if your driving habits frequently includes
one or more of the following driving conditions:
• Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) with outside temperatures re-
maining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
• Driving in dusty conditions.

PERIODIC MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. [ ]: At the mileage intervals only
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts i f found
damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to the FL section.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genuine NISSAN long life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% an ti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory fill coolant.
(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.
