Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The 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 in a frontal
collision. The SRS composition which is available to NISSAN MODEL D22 is as follows (The composition
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.
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 dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
+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.
PRECAUTION

DIAGNOSTIC PROCEDURE 6 (Continued from
DIAGNOSTIC PROCEDURE 2)
Inspecting SRS malfunctioning record
Is it the first time for maintenance of
SRS?
Yes
cNo
ªSELF-DIAG [PAST]º
(which was previously
entered) is still retained in
memory.
Go to DIAGNOSTIC PRO-
CEDURE 4 (RS-3028).
Go to DIAGNOSTIC PROCEDURE 8
(RS-3032).
DIAGNOSTIC PROCEDURE 7 (Continued from
DIAGNOSTIC PROCEDURE 3) (
without
CONSULT-II)
Inspecting SRS malfunctioning record
Is it the first time for maintenance of
SRS?
Yes
cNo
Diagnosis results (previ-
ously stored in the
memory) might not be
erased after repair.
Go to DIAGNOSTIC PRO-
CEDURE 5, step 5 (RS-
3029).
GO TO DIAGNOSTIC PROCEDURE 8
(RS-3032).Further inspection cannot be
performed without CONSULT-II.
DIAGNOSTIC PROCEDURE 8 (with CONSULT-II)
Inspecting SRS intermittent malfunction by using CON-
SULT-II Ð Diagnosis mode
1. Turn ignition switch ªOFFº.
2. Connect CONSULT-II to data link connector.
3. Turn ignition switch ªONº.
4. Touch ªSTARTº.

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 must 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.
