If air bag warning lamp blinks or stays ON (at the Usermode),
it shows the spiral cable may be snapped due to its improper
position. Perform self-diagnosis again (use CONSULT-II or
warning lamp). If a malfunction is detected, replace the spi-
ral cable with a new one.
14. Perform self-diagnosis again to check that no malfunction is
detected.

PANELº in BT section of Service Manual (Pub. No. SM9E-
D22BG0) for details.
2. Disconnect passenger air bag module connector.
3. Remove bolts and special hex using the TAMPER RESIS-
TANT TORX (Size T30) from front passenger air bag mod-
ule.
4. Remove instrument panel assembly. Refer to Service

Disposal of Air Bag Module and Seat Belt
Pre-tensioner
+Before disposing of air bag module and seat belt pre-tensioner, or vehicles equipped with such systems,
deploy the systems. If such systems have already been deployed due to an accident, dispose of them as
indicated in ªDISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONERº (RS-3013).
+When deploying the air bag module and seat belt pre-tensioner, always use the Special Service Tool;
Deployment tool KV99106400.
+When deploying the air bag module and seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
deployment component.
+When deploying air bag module and seat belt pre-tensioner, a fairly loud noise is made, followed by
smoke being released. The smoke is not poisonous, however, be careful not to inhale smoke since it
irritates the throat and can cause choking.
+Always activate one air bag module at a time.
+Due to heat, leave air bag module unattended for more than 30 minutes after deployment. Also leave
seat belt pre-tensioner unattended for move than 10 minutes after deployment.
+Be sure to wear gloves when handling a deployed air bag module and seat belt pre-tensioner.
+Never apply water to the deployed air bag module and seat belt pre-tensioner.
+Wash your hands clean after finishing work.
+Place the vehicle outdoors with an open space of at least 6 m (20 ft) on all sides when deploying air
bag module and seat belt pre-tensioner while mounted in vehicle.
+Use a voltmeter to make sure the vehicle battery is fully charged.
+Do not dispose of the air bag module and seat belt pre-tensioner un-deployed.
DEPLOYMENT PROCEDURES FOR AIR BAG
MODULE (OUTSIDE OF VEHICLE)
Unless the vehicle is being scrapped, deploying the air bag in the
vehicle is not recommended. This may cause damage to the
vehicle interior.
Anchor air bag module bracket (SST: KV99105300) in a vise
secured to a firm foundation during deployment.
Deployment of driver air bag module (Outside of
vehicle)
1. Using wire, secure air bag module to air bag module bracket
(SST: KV99105300) at two places.
CAUTION:
Use wire of at least 1 mm (0.04 in) diameter.
2. Firmly secure air bag module bracket (SST: KV99105300)
with air bag module attached in a vise.
3. Connect deployment tool adapter (SST: KV99109700) to
deployment tool (SST: KV99106400) to air bag module con-
nector.

Trouble Diagnoses Introduction
CAUTION:
+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 with yellow harness connector.
+Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
+Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using ªAIR BAGº warning lamp, and/or CONSULT-II. The
reading of these results is accomplished using one of two modes Ð ªUser modeº and ªDiagnosis modeº.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the ªAIR BAGº warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the ªAIR BAGº warning lamp and CONSULT-II are as follows:
User mode Diagnosis mode Display type
ªAIR BAGº warning lamp X X ON-OFF operation
CONSULT-II Ð X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by ªAIR BAGº warning lamp.
DIAGNOSIS MODE FOR CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result (also indicated by the warning lamp flashes in the Diagnosis mode) is
displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring repairs.
+ªSELF-DIAG [PAST]º
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.
+ªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.
+ªECU DISCRIMINATED NO.º
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber. This number will be displayed on the CONSULT-II screen, as shown at left. When replacing the
diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with
a correct unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL D22, the diagnosis sensor unit classification number assigned are as follows:
MODEL ECU DISCRIMINATED NO.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time. After the malfunc-
tion is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
+ªSELF-DIAG [PAST]º
Return to the ªSELF-DIAG [CURRENT]º CONSULT-II screen
by pushing ªBACKº key of CONSULT-II and select ªSELF-
DIAG [CURRENT]º in ªSELECT DIAG MODEº. Touch
ªERASEº in ªSELF-DIAG [CURRENT]º mode.
NOTE:
If the memory of the malfunction in ªSELF-DIAG [PAST]º is
not erased, the User mode shows the system malfunction by
the operation of the warning lamp even if the malfunction is
repaired completely.
+ªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return Diagnosis mode to User mode by switching the ignition ªOFFº for at
least 1 second, then back ªONº. At that time, the self-diagnostic result is cleared.
How to Perform Trouble Diagnoses for Quick
and Accurate Repair
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
