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.

System Description

EKS009N9

UNIFIED METER CONTROL UNIT

●

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.

●

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.

●

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.

●

Odometer/trip meters and A/T indicator segments can be checked in diagnosis mode.

●

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.

●

Approximately 60 seconds after turning the ignition switch from the ON to the OFF position

●

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,
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.
