The SRS system composition which is available to NISSAN MODEL B15 is as follows:
For a frontal collision The Supplemental Restraint System consists of driver air bag module (located in the center of the steer- ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
For a side collision The Supplemental Restraint System consists of front side air bag module (located in the outer side of front seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision). Information necessary to service the system safely is included in the RS section of this Service Manual. 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 should be per- formed by an authorized NISSAN 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 RS 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 harness connectors. Wiring Diagrams and Trouble Diagnosis NIEL0002 When you read wiring diagrams, refer to the following:

Speedometer, odo/trip meter, tachometer (if equipped), fuel gauge and water temperature gauge are con- trolled totally by control unit built-in combination meter.
Digital meter is adopted for odo/trip meter.* *The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter is erased when the battery cable is disconnected.
Odo/trip meter segment can be checked in diagnosis mode.
Meter/gauge can be checked in diagnosis mode. HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER NIEL0042S07 SEL253V NOTE: Turn ignition switch to the “ON” position to operate odo/trip meter. POWER SUPPLY AND GROUND CIRCUIT NIEL0042S08 Power is supplied at all times:
through 10A fuse [No. 12, located in the fuse block (J/B)]
to combination meter terminal 25 (without tachometer) or 42 (with tachometer). With the ignition switch in the ON or START position, power is supplied:
through 10A fuse [No. 30, located in the fuse block (J/B)]
to combination meter terminal 26 (without tachometer) or 41 (with tachometer). Ground is supplied:
to combination meter terminal 27 (without tachometer) or 48 (with tachometer)
through body grounds M28 and M54. WATER TEMPERATURE GAUGE NIEL0042S01 The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based on the resistance of the thermal transmitter. As the temperature of the coolant increases, the resistance of the thermal transmitter decreases. A variable ground is supplied to terminal 31 (without tachometer) or 43 (with tachometer) of the combination meter for the water temperature gauge. The needle on the gauge moves from “C” to “H”. TACHOMETER NIEL0042S02 The tachometer indicates engine speed in revolutions per minute (rpm). The tachometer is regulated by a signal:
from terminal 32 of the ECM
to combination meter terminal 45 for the tachometer. METERS AND GAUGES System Description EL-86 FUEL GAUGE NIEL0042S03 The fuel gauge indicates the approximate fuel level in the fuel tank. The fuel gauge is regulated by a variable ground signal supplied:
to combination meter terminal 30 (without tachometer) or 44 (with tachometer) for the fuel gauge
from terminal 2 of the fuel level sensor unit and fuel pump
through terminal 5 of the fuel level sensor unit and fuel pump, and
through body grounds B13 and B19. SPEEDOMETER NIEL0042S04 The combination meter receives a voltage signal from the vehicle speed sensor for the speedometer. The voltage is supplied:
to combination meter terminal 29 (without tachometer) or 47 (with tachometer) for the speedometer
from terminal 1 of the vehicle speed sensor. The speedometer converts the voltage into the vehicle speed displayed.

Odo/trip meter segment can be checked in diagnosis mode.
Meters/gauges can be checked in diagnosis mode. HOW TO ALTERNATE DIAGNOSIS MODE NIEL0151S02 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. Release odo/trip meter switch 1 second after ignition switch is turned ON. 5. Push odo/trip meter switch three times within 7 seconds. SEL110V 6. All odo/trip meter segments should be turned on. NOTE: If some segments are not turned on, unified meter control unit with odo/trip meter should be replaced. At this point, the unified control meter is turned to diagnosis mode. WEL128 7. Push odo/trip meter switch. Indication of each meter/gauge should be as shown in figure at left during pushing odo/trip meter switch if it is not malfunctioning. NOTE: It takes a few seconds for indication of fuel gauge and water tem- perature gauge to become stable. 8. Turn ignition switch to OFF or start engine to cancel diagnosis mode.
