                                                                                                                         A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                          EKS00DCY


The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along                            B
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              C
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:                                                                                                                 D
G    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.                                                                     E
G    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.                                                                                    F
G    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.

UNIFIED METER CONTROL UNIT
G    Speedometer, odometer, tachometer, fuel gauge, oil pressure gauge, voltage gauge, and water tempera-
     ture gauge are controlled by the unified meter control unit, which is built into the combination meter.
G    Warning indicators are controlled by signals drawn from the CAN communication system, BCM (body con-
     trol module), and components connected directly to the combination meter.
G    Digital meter is adopted for odometer/trip meters*, as well as the A/T position indicator display.
     *The record of the odometer is kept even if the battery cable is disconnected.
G    Odometer/trip meters and A/T indicator segments can be checked in diagnosis mode.
G    Meters/gauges can be checked in diagnosis mode.
NOTE:
Under the following conditions, the meters will perform a homing function. The meter pointers will move down
slightly and then move back to the resting position. This is a normal design condition.
G    Approximately 60 seconds after turning the ignition switch from the ON to the OFF position
G    If the battery is disconnected and then reconnected

Illumination control
The unified meter control unit outputs the speedometer, odometer/trip meters, tachometer, oil pressure gauge,         A
voltage gauge, A/T indicator, fuel and temperature gauge lighting when the ignition switch is turned on. When
the lighting switch is turned on, the illumination control switch can be used to adjust the brightness of the com-
bination meter illumination and the odometer/trip meters and meter illumination.                                      B

SELF-DIAGNOSIS FUNCTION
The following items can be checked during Combination Meter Self-Diagnosis Mode.
G   Gauge sweep and present gauge values.
G   Illuminates all odometer/trip meters and A/T indicator segments.
G   Illuminates all micro controlled lamps/LEDs regardless of switch position.
G   Displays estimated present battery voltage.
G   Displays seat belt buckle switch LH status.
HOW TO INITIATE COMBINATION METER SELF-DIAGNOSIS MODE
NOTE:
Once entered, Combination Meter Self-Diagnosis Mode will function with the ignition switch in ON or START.
Combination Meter Self-Diagnosis Mode will exit upon turning the ignition switch to OFF or ACC.
To initiate Combination Meter Self-Diagnosis Mode, refer to the following procedure.
1. Turn the ignition switch ON, while pressing the odometer/trip meter switch for 5 - 8 seconds.
     NOTE:
     If the diagnosis function is activated the odometer/trip meter will display tESt.
COMBINATION METER SELF-DIAGNOSIS MODE FUNCTIONS
To interpret Combination Meter Self-Diagnosis Mode functions, refer to the following table.

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
      METER diagnosis mode                                              Description
       SELF-DIAG RESULTS     Displays combination meter self-diagnosis results.
         DATA MONITOR        Displays combination meter input/output data in real time.
     CAN DIAG SUPPORT MNTR   The result of transmit/receive diagnosis of CAN communication can be read.


CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
    SULT-II CONVERTER to the data link connector, then turn igni-
    tion switch ON.
