PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS007X5
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.

Revision: 2005 July 2005 FX
DRIVE COMPUTER
Refer to Owner′s Manual for drive computer operating instructions.
TRIP Switch
When “TRIP” switch is pressed, display TRIP screen. As TRIP infor-
mation, it indicates journey time (TIME), trip odometer (DIST), aver-
age vehicle speed (AVG).
Pressing “TRIP” switch once cycles display from TRIP 1 →TRIP
2 → Display OFF →TRIP 1.
“TIME”

Journey time indication is performed by reset or battery connec-
tion.

When pushing “TRIP RESET” or “TRIP” switch more than
approximately 1.5 seconds, journey time will be reset.

If journey time is reset, journey distance and average speed will
be reset at the same time.
“DIST”

Trip odometer indication is performed by vehicle speed signal.

When pushing “TRIP RESET” or “TRIP” switch more than approximately 1.5 seconds, driving distance will
be reset.

If trip odometer is reset, journey time and average speed will be reset at the same time.
“AVG”

Average speed indication is performed by running distance and running time.

Indication will be renewed every 30 seconds.

When pushing “TRIP RESET” or “TRIP” switch more than approximately 1.5 seconds, average speed will
be reset.

After reset operation, the displays shows “ ” for 30 seconds.
FUEL ECON Switch
When “FUEL ECON” switch is pressed, display FUEL ECON screen.
As FUEL ECON information, it indicates average fuel consumption
(AVG), distance to empty (DTE).
Pressing “FUEL ECON” switch once cycles display from FUEL
ECON →Display OFF →FUEL ECON.
“AVG” (Average Fuel Consumption)

Average fuel consumption indication is performed by fuel con-
sumption signal and vehicle speed signal after system is reset.

Indication will be renewed every 30 seconds.

When pushing “TRIP RESET” or “FUEL ECON” switch more
than approximately 1.5 seconds, average fuel economy will be
reset.

After reset operation, the display shows “ . ” until the vehicle is driven 500 m (1,600 ft.) or 30 seconds
has passed.
“DTE” (Distance to Empty)

Distance to empty receives via CAN communication and indicates values calculated by meter.

Display range is max 999 miles (max 999 km).

If low-fuel WARNING is received from meter via CAN communication, distance to empty indication will be
“”.

Indication will be renewed every 30 seconds.

Turning on “DAY/NIGHT” switch, DAY MODE or NIGHT MODE
is indicated for present mode.

If press “DAY/NIGHT” again when display adjustment lumi-
nance, change DAY-NIGHT (NIGHT-DAY) mode (screen of
adjustment luminance).
As follows:

Press “PREV” or not operate for 10sec. when displayed screen
of adjustment luminance, back to default screen (same mode).

Can adjust luminance by “DISP” switch. Light can be adjusted by pressing “+” (bright) or “–” (dark).

Adjustment range is a 12 stage (MIN to MAX) and default set value is 10 (DAY) and 4 (NIGHT).
WARNING INDICATIONS
When BCM receives warning signal from some control units or sensors, then combination meter warning lamp
is illuminated.
Then BCM sends warning signal to display unit warning indications on the screen.
AV COMMUNICATION LINE
Display unit is controlled by the following unit with AV communication line.

A/C and AV switch
CAN Communication System DescriptionAKS007Z5
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.
