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-1018).
+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.
CHECKING DEPLOYMENT TOOL
Connecting to battery
CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood
blocks approximately 5 m (16 ft) away from the vehicle.
+Wait 3 minutes after the vehicle battery is disconnected
before proceeding.
+Connect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
Make sure the polarity is correct. The right side lamp in the
tool, marked ªdeployment tool powerº, should glow with a
green light. If the right side lamp glows red, reverse the
connections to the battery.

DEPLOYMENT OF AIR BAG MODULE AND SEAT
BELT PRE-TENSIONER WHILE MOUNTED IN
VEHICLE
When disposing of a vehicle, deploy air bag modules and seat
belt pre-tensioners while they are mounted in vehicle.
CAUTION:
When deploying air bag module or seat belt pre-tensioner,
ensure vehicle is empty.
1. Disconnect both the vehicle battery cables and wait 3 min-
utes.
2. Disconnect air bag modules and seat belt pre-tensioners
connector.
3. Connect deployment tool [SST: KV99106400] to air bag
module or seat belt pre-tensioner.
For front passenger air bag module and side air bag module,
attach deployment tool adapter [SST: KV99108300] to the
tool connector. For seat belt pre-tensioner, attach deploy-
ment tool adapter [SST: KV99108200 (KV999R0020)] to the
tool connector.
4. Connect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
5. The lamp on the right side of the tool, marked ªdeployment
tool powerº, should glow green, not red.
6. Press the button on the deployment tool. The left side lamp
on the tool, marked ªair bag connector voltageº, will illuminate
and the air bag module or seat belt pre-tensioner will deploy.
CAUTION:
Activate only one air bag module or seat belt pre-tensioner
at a time.
DISPOSING OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER
Deployed air bag modules and seat belt pre-tensioners are very
hot. Before disposing of air bag module, and seat belt pre-
tensioner, wait at least 30 minutes, and 10 minutes, respectively.
Seal them in a plastic bag before disposal.
CAUTION:
+Never apply water to a deployed air bag module and seat
belt pre-tensioner.
+Be sure to wear gloves when handling a deployed air
bag module and seat belt pre-tensioner.
+No poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since
it irritates throat and can cause choking.
+Do not attempt to disassemble air bag module and seat
belt pre-tensioner.
+Air bag module and seat belt pre-tensioner can not be
re-used.
+Wash your hands clean after finishing work.

Trouble Diagnoses Introduction
CAUTION:
+Do not use electrical test equipment to check SRS harness connectors unless instructed to in
this Service Manual. SRS wiring harnesses can be identified by yellow harness protector or yel-
low insulation tape before the harness connectors.
+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, ªSEAT BELTº warning lamp
(Models except for Europe) 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 and/or ªSEAT BELTº warning lamp (Mod-
els except for Europe).
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the ªAIR BAGº warning lamp, ªSEAT BELTº warning lamp (Models except for
Europe) and CONSULT-II are as follows:
User mode Diagnosis mode Display type
ªAIR BAGº warning lamp X X ON-OFF operation
ªSEAT BELTº warning lamp
(Models except for Europe)X Ð ON-OFF operation
CONSULT-II Ð X Monitoring
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. The
diagnosis sensor unit classification number varies depending on SRS configuration.
For NISSAN MODEL Y61, the diagnosis sensor unit classification numbers are as follows.
MODEL ECU DISCRIMINATED NO.
WagonModel with dual air bags and side air bag 5A0F
Model with dual air bags 5A11
Model with single air bag 5A13

HOW TO CHANGE SELF-DIAGNOSIS MODE
With CONSULT-II
From User mode to Diagnosis mode
After selecting AIR BAG on the ªSELECT SYSTEMº screen, User mode automatically changes to Diagno-
sis mode.
From Diagnosis mode to User mode
To return to User mode from Diagnosis mode, touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears, Diagnosis mode automatically changes to User mode.
Without CONSULT-II
From User mode to Diagnosis mode
Diagnosis mode activates only when a malfunction is detected,
by pressing the driver's door switch at least 5 times within 7
seconds after turning the ignition ªONº. SRS will not enter Diag-
nosis mode if no malfunction is detected.
From Diagnosis mode to User mode
After a malfunction is repaired, switch the ignition ªOFFº for at least 1 second, then back ªONº. Diagnosis
mode returns to User mode. If switching from Diagnosis mode to User mode is required while malfunction
is being detected, switch the ignition ªOFFº, then back ªONº and press the driver's door switch at least 5
times within 7 seconds.
