Incident Simulation Tests
INTRODUCTION
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The
following section illustrates ways to simulate the conditions/environment under which the owner experiences
an electrical incident.
The section is broken into the six following topics:
IVehicle vibration
I Heat sensitive
I Freezing
I Water intrusion
I Electrical load
I Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of
the problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the illustration below.
Connectors & harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gen-
tly shake each connector and harness while monitoring the system for the incident you are trying to dupli-
cate. This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs
intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean
the terminals on related connectors in the system.
Sensors & relays
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.

General maintenance includes those items which should be checked during normal day-to-day operation of
the vehicle. They are essential if the vehicle is to continue functioning correctly. Owners can perform the
checks and inspections themselves, or they can be carried out by a NISSAN dealer.
ItemReference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be checked periodically, unless otherwise specified.
Tires Check the pressure with a gauge weekly when at a service station, including the spare,
and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive
wear. Ð
Windshield wiper blades Check for cracks or wear if not functioning correctly. Ð
Doors and engine hood Check that all doors, the engine hood, the trunk lid and back door
function correctly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch prevents the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication more
often. MA-45
Tire rotation Tires should be rotated every 5,000 km (3,000 miles). MA-43
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle etc.
Lights Make sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating correctly and installed securely. Also check headlight aim. Ð
Warning lights and buzzers/chimes Make sure that all warning lights and buzzers/chimes are
functioning correctly. Ð
Steering wheel Check that it has the specified play. Check for changes in the steering
operation, such as excessive free play, hard steering or strange noises. Free play: Less than 35 mm (1.38 in) Ð
Seat belts Check 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 of damage. MA-46
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.
Windshield washer fluid Check that there is adequate fluid in the tank.
Engine coolant level Check the coolant level when the engine is cold. MA-22
Engine oil level Check the level after parking the vehicle (on level ground) and turning off the
engine. MA-21
Brake and clutch fluid level Make sure that the brake fluid level is between the ªMAXº and
ªMINº lines on the reservoir. MA-36/MA-40
Battery Check the fluid level in each cell. It should be between the ªMAXº and ªMINº lines. Ð

draining. Do not remove drain cock by loosening it exces-
sively.
If water does not drain properly, move the priming pump up and
down.
Type B
Loosen air bleeder screw from the sedimentor cover and then
loosen drain cock and drain water.

IIf the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
I Erasing the emission-related diagnostic information using CONSULT-II is easier and quicker than
switching the diagnostic test mode using the data link connector.
NATS (Nissan Anti-Theft System)
IIf the security indicator lights up with the ignition switch in
the ªONº position or ªNATS MALFUNCTIONº is displayed
on ªSELF-DIAG RESULTSº screen, perform self-diagnostic
results mode with CONSULT-II using NATS program card.
Refer to ªNATS (Nissan Anti-Theft System)º in EL section.
I Confirm no self-diagnostic results of NATS is displayed
before touching ªERASEº in ªSELF-DIAG RESULTSº mode
with CONSULT-II.
I When replacing ECM, initialization of NATS system and
registration of all NATS ignition key IDs must be carried out
with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.
Malfunction Indicator (MI)
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
I If the MI does not light up, refer to EL section (ªWARNING
LAMPS AND CHIMEº) or see EC-310.
2. When the engine is started, the MI should go off. If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
If MI illuminates or blinks irregularly after starting engine,
water may have accumulated in fuel filter. Drain water from
fuel filter. Refer to MA section.

Description
The accelerator switch is installed to the accelerator pedal assem-
bly. The switch senses accelerator position and sends an ON-OFF
signal to the ECM. The ECM uses the signal to control the fuel cut
operation at deceleration for better fuel efficiency.
