TROUBLE DIAGNOSIS - SPECIFICATION VALUEPFP:00031
DescriptionABS00E4K
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:

B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)

A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)

MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

PRECAUTIONSPFP:00001
DescriptionAAS000EV
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AAS000EW
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To 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.

Improper 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.

Do 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.
Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM -
NATS) (If Equipped)
AAS000EX
NVIS/IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS/IVIS
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NVIS/IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

When NVIS/IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition switch is in
"ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
software is necessary.
Regarding the procedures of NVIS/IVIS (NATS) initialization and NVIS/IVIS (NATS) ignition key ID regis-
tration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).
Therefore, CONSULT-II NVIS/IVIS (NATS) software (program card and operation manual) must be kept
strictly confidential to maintain the integrity of the anti-theft function.

When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be regis-
tered into NVIS/IVIS (NATS).

When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.

HEADLAMP - XENON TYPE -PFP:26010
Component Parts and Harness Connector LocationAKS007M9
System DescriptionAKS007MA
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central
processing unit) located in the IPDM E/R controls the headlamp high and headlamp low relay coils. These
relays, when energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.

to front combination lamp LH terminal 5.
Ground is supplied

to front combination lamp RH terminal 7

through grounds E21, E50 and E51,

to front combination lamp LH terminal 7

through grounds E21, E50 and E51.
With power and ground supplied, the high beam headlamps illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
The unified meter and A/C amp. that received the high beam request signal by BCM across the CAN commu-
nication makes a high beam indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned OFF.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
AUTO LIGHT OPERATION (IF EQUIPPED)
Refer to LT- 5 5 , "System Description" in “AUTO LIGHT SYSTEM”.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-186, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP
Xenon type lamps are used for to the low beam headlamps. Xenon bulbs do not use a filament. Instead, they
produce light when a high voltage current is passed between two tungsten electrodes through a mixture of
xenon (an inert gas) and certain other metal halides. In addition to strong lighting power, electronic control of
the power supply gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.

The light produced by the headlamps is white color similar to sunlight that is easy to the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

Retroreflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.

Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System DescriptionAKS007MB
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS0080S
Refer to LAN-30, "CAN Communication Unit" .
