Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                            EKS0086Z


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:
q    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.
q    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.
q    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.
Maintenance Information                                                                                        EKS008W0


If any of following part is replaced, always replace with new* one.
If it's not (or fail to do so), the electrical system may not be operated properly.
*: New one means a virgin control unit that has never been energized on-board.

CAN SYSTEM
q   Do not apply voltage of 7.0V or higher to the measurement terminals.
q   Use the tester with its open terminal voltage being 7.0V or less.
q   Be sure to turn ignition switch off and disconnect negative battery cable before checking the circuit.

HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
q   The CAN communication signals (vehicle speed signal) from ABS actuator and electric unit (control unit),
    and the memory signals from the meter memory circuit are processed by the combination meter, and the         M
    mileage is displayed.
q   Operating the odo/trip meter switch allows switching the mode in the refer to DI-38, "DRIVE COMPUTER"
    .
q   When resetting with trip A displayed, only trip A display is reset (same as trip B).

WATER TEMPERATURE WARNING/INDICATOR LAMP
The water temperature warning/indicator lamp indicate the engine coolant temperature.
ECM provides a engine coolant temperature signal to combination meter for water temperature warning/indi-
cator lamp via CAN communication line.
When turn ignition switch ON, water temperature warning/indicator lamp will be ON with red color for 1 sec-
ond.
After engine started,
q   Water temperature warning/indicator lamp will be ON with blue color while engine coolant temperature is
    less than 55
