YES >> Continuity exists. Connect 4WD/ABS control unit connector, check again.
NO >> Check ABS warning lamp harness.
4WD Warning Lamp Does Not Go Out Several Seconds After Engine Is Started.
(Drive Mode Indicator Lamp Goes Out.)
EFS001BS
1.USING CONSULT, PERFORM SELF-DIAGNOSIS
4WD warning lamp does not go out several seconds after the engine is started. (Drive mode indicator lamp
goes out.)
Is inspection result OK?
YES >> No malfunction detected. Perform inspection again.
NO >>
●Determine the location of the malfunction according to the result of self-diagnosis using CON-
SULT. (Malfunction is present in the 4WD system.)
●CONSULT-II does not display ABS -related trouble codes. Proceed to 2.

NOTE:
If the hood lock cable is bent or deformed, replace it.
1. Confirm hood lock secondary latch securely engages secondary
striker by releasing it from a height of approximately 200 mm
(7.87 in).
2. Confirm front end of the hood rises by approximately 20 mm
(0.79 in) when pulling the hood opener. Also confirm hood
opener returns to the original position.

TROUBLE DIAGNOSIS
Ambient Sensor Circuit
EJS001HB
COMPONENT DESCRIPTION
Ambient Sensor
The ambient sensor is attached on the hood lock stay. It detects
ambient temperature and converts it into a resistance value which is
then input into the auto amplifier.
AMBIENT TEMPERATURE INPUT PROCESS
The automatic amplifier includes a processing circuit for the ambient sensor input. However, when the temper-
ature detected by the ambient sensor increases quickly, the processing circuit retards the auto amp. function.
It only allows the auto amp. to recognize an ambient temperature increase of 0.33°C (0.6°F) per 100 seconds.
As an example, consider stopping for a cup of coffee after high speed driving. Although the actual ambient
temperature has not changed, the temperature detected by the ambient sensor will increase. This is because
the heat from the engine compartment can radiate to the front grille area, location of the ambient sensor.
DIAGNOSTIC PROCEDURE
SYMPTOM: Ambient sensor circuit is open or shorted. (21 or -21 is
indicated on auto amp. As a result of conducting Self-diagnosis
STEP 2.)
1. CHECK VOLTAGE BETWEEN AMBIENT SENSOR HARNESS CONNECTOR AND GROUND
Disconnect ambient sensor harness connector.

General MaintenanceELS000AL
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 do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
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.
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
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing 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 prop-
erly. 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.BL-4
,BL-8
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-38
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 head-
lamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
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, a dju sters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.SB-3
