WARNING CHIMEPFP:24814
System DescriptionEKS00L9D
lBuzzer for warning chime system is installed in the combination meter.
lThe buzzer sounds at the following conditions:
–When combination meter receives buzzer output signal with CAN communication line
–When combination meter judges warning chime sound condition is found
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 50A fusible link (letterG, located in the fuse and fusible link box)
lto BCM terminal 57.
With ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No. 1, located in the fuse block (J/B)]
lto BCM terminal 3.
Ground is supplied
lto BCM terminal 55
lthrough grounds M21, M80 and M83.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver's door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.
lBCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to combination
meter with CAN communication line.
lWhen combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer toBCS-3, "
COMBINATION SWITCH READING FUNCTION".
KEY REMINDER WARNING CHIME
Key reminder chime sounds, at the same time, when key reminder system starts operating.
key reminder chime also sounds when the following three conditions are simultaneously met.
lKey is inserted in the ignition key cylinder
lDriver¢s door is opened
lThe setting of driver¢s door lock knob is “LOCK”
For information regarding key reminder system, refer toBL-21, "
POWER DOOR LOCK SYSTEM".
LOW-FUEL WARNING CHIME
Low-fuel warning chime sounds, when low-fuel warning lamp is turned ON.
Combination meter sounds warning chime three times when low-fuel warning lamp turns ON.

COMPASS
COMPASS
PFP:24835
System DescriptionEKS00M4Z
This unit displays earth magnetism and heading direction of vehicle.
DIRECTION DISPLAY
Press “COMP” switch (1) when ignition switch is in “ON” or “START” position. The direction is displayed.
Pressing “COMP” switch (1) for a second turns off the display (2).
NOTE:
lDo not install the ski rack, antenna, etc. which are attached to
the vehicle by means of a magnet. They affect the operation of
the compass.
lThe compass may not indicate the correct compass point in tun-
nels or while driving up or down a steep hill. (The compass
returns to the correct compass point when the vehicle moves to
an area where the geomagnetism is stabilized.)
lWhen cleaning the mirror, use a paper towel or similar material
dampened with glass cleaner. Do not spray glass cleaner
directly on the mirror as that may cause the liquid cleaner to
enter the mirror housing.
Zone Variation Change ProcedureEKS00MS2
The difference between magnetic north and geographical north is known as variance. In some areas, this dif-
ference can sometimes be great enough to cause false compass reading.
Follow these instructions to set the variance for the particular location if this happens:
1. Press “COMP” switch for more than 3 seconds. The current zone number appears on the display.
2. Find the current location and variance one number on the zone variation chart.
3. Press “COMP” switch until the new zone number appears on the display. After releasing the switch, the
display shows a compass direction within a few seconds.

PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EBS01KC5
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
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 must be per-
formed by an authorized NISSAN/INFINITI 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 SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
On Board Diagnostic (OBD) System of EngineEBS01KC6
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
lBe sure to turn the ignition switch OFF and disconnect the battery negative cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MI to light up.
lBe sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
lCertain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector. For description and how to disconnect, refer toPG-75, "
HAR-
NESS CONNECTOR".
lBe sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.
lBe sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel system, etc.
lBe sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.
PrecautionsEBS01KC7
lAlways use a 12 volt battery as power source.
lDo not attempt to disconnect battery cables while engine is
running.
lBefore connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect battery
negative cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
lBefore removing parts, turn ignition switch OFF and then
disconnect battery negative cable.

Fuel Injection Control SystemEBS01KCE
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.
