                                            PRECAUTIONS

                                            Supplemental Restraint System (SRS) ``AIR
                                            BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal
collision. The SRS system composition which is available to NISSAN MODEL D22 is as follows (The com-
position varies according to the destination and optional equipment.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in the RS 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 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 RS section.
q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
     Service Manual. Spiral Cable and wiring harnesses (except ``SEAT BELT PRE-TENSIONER'')
     covered with yellow insulation either just before the harness connectors or for the complete har-
     ness are related to the SRS.

           Unified Control Meter System Description
           UNIFIED CONTROL METER
           Speedometer, odo/trip meter, tachometer, fuel gauge and water
           temperature gauge are controlled totally by unified meter control
           unit.




           Meter/gauge Operation and Odo/Trip Meter
           Segment Check in Diagnosis Mode
           DIAGNOSIS FUNCTION
           q   Odo/trip meter segment can be checked in diagnosis mode.
           q   Meters/gauges can be checked in diagnosis mode.




           HOW TO ALTERNATE DIAGNOSIS MODE
           1. Turn ignition switch to ON and change odo/trip meter to
              ``TRIP A'' or ``TRIP B''.
           2. Turn ignition switch to OFF.
           3. Turn ignition switch to ON when pushing odo/trip meter
              switch.
           4. Confirm that trip meter indicates ``000.0''.
           5. Push odo/trip meter switch more than three times within 5
              seconds.
           6. All odo/trip meter segments should be turned on.
 SEL110V   NOTE: If some segments are not turned on, unified meter
                   control unit should be replaced.
              At this point, the unified control meter is turned to diagnosis
              mode.




           7. Push odo/trip meter switch. Indication of each meter/gauge
              should be as shown left during pushing odo/trip meter switch
              if it is no malfunctioning.
           NOTE: It takes about 1 minute for indication of fuel gauge
                     to become stable.

          Flexible Print Circuit (FPC) (Models with
          Tachometer)
          Tachometer, fuel gauge and water temperature gauge are con-
          nected with unified meter control unit (speedometer) by Flexible
          Print Circuit (FPC) connector. When replace or remove and
          install unified control unit (speedometer), disconnect and con-
          nect FPC connector according to the following steps.




          DISCONNECT
          1. Open connector cover.
          2. Release connector lock by holding both ends of it and pull-
             ing it up.
          3. Disconnect FPC by pulling it up.




SEL109V

          CONNECT
          1. Insert FPC into connector and lock connector pushing FPC
             downward.
          2. Check secure connection of FPC.
          3. Check continuity of check land terminals for secure connec-
             tion of FPC.
               Resistance: 0
          4. Close connector cover.
