2001 NISSAN ALMERA N16 warning lamp circuit

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NJEL0001The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to NISSAN MODEL N16 is as follows (The compo-
sition varies according to the destination and optional equipment.):
+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 theRS sectionof 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 connector.
Wiring Diagrams and Trouble DiagnosisNJEL0002When you read wiring diagrams, refer to the following:
+Refer to GI-12, ªHOW TO READ WIRING DIAGRAMSº
+Refer to EL-10, ªPOWER SUPPLY ROUTINGº for power distribution circuit
When you perform trouble diagnosis, refer to the following:
+Refer to GI-32, ªHOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSESº
+Refer to GI-21, ªHOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENTº
Check for any Service bulletins before servicing the vehicle.

Combination Meter Calibration
After replacing a combination meter, it might be necessary to cali-
brate the fuel gauge/low fuel warning lamp. In case the fuel warn-
ing lamp is flashing after replacing the combination meter perform
the following:
1. Press both reset buttons.
2. Turn the ignition ONand keep the reset buttons depressed
for at least 5 seconds.
3. Release both reset buttons.
The low fuel warning lamp will stop flashing and the combina-
tion meter will show CALL and possibly CALL FAIL. Showing
CALL FAIL does not indicate a concern as this might be related
to the current (unexpected) amount of fuel in the tank.
