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 modules 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 mod-
ule or seat belt pre-tensioner.
For front passenger's air bag module and front side air bag
module (built-in type), attach deployment tool adapter [SST:
KV99108300] to the tool connector.
For seat belt pre-tensioner attach deployment tool adapter
[SST: KV99108200].
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

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:
lNever apply water to a deployed air bag module and seat
belt pre-tensioner.
lBe sure to wear gloves when handling a deployed air
bag module and seat belt pre-tensioner.
lNo poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since
it irritates throat and can cause choking.
lDo not attempt to disassemble air bag module and seat
belt pre-tensioner.
lAir bag module and seat belt pre-tensioner cannot be
re-used.
lWash your hands clean after finishing work.

Trouble Diagnoses Introduction
CAUTION:
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and SRS wiring harnesses (except ªSEAT BELT PRE-TENSIONER
CONNECTORº) can be identified by yellow harness connector (and with yellow harness protec-
tor or yellow insulation tape before the harness connectors.
lDo not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
lKeep 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 XON-OFF operation
CONSULT-II Ð XMonitoring
lSeat belt pre-tensioner system can only be diagnosed by CONSULT-II.
DIAGNOSIS MODE FOR CONSULT-II
lSELF-DIAG [CURRENT]
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requir-
ing repairs.
lSELF-DIAG [PAST]
Diagnosis results previously stored in the memory (also indicated by the warning lamp flashes in the
Diagnosis mode) are displayed on the CONSULT-II screen. The stored results are not erased until
memory erasing is executed.
lTROUBLE DIAG RECORD
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.
lªECU DISCRIMINATED NO.º
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber (refer to the table below). This number will be displayed on the CONSULT-II screen. When replac-
ing the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replace-
ment with a correct unit can be checked by confirming this classification number on the CONSULT-II
screen.
For NISSAN MODEL P11, the diagnosis sensor unit classification numbers are as follows:
MODEL ECU DISCRIMINATED NO.
Models with single air bag and seat belt pre-tensioner A914
Models with dual air bags and seat belt pre-tensioner A915
Models with dual air bags, side air bag and seat belt pre-tensioner A916

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.
How to Change Self-diagnosis Mode without CONSULT-II
From User Mode to Diagnosis Mode
Diagnosis mode activates only when a malfunction is detected, by turning ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
SRS will not enter Diagnosis mode, if no malfunction is detected.
From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagno-
sis mode is returned to User mode.
If switching Diagnosis mode to User mode is required while malfunction is being detected, by turning igni-
tion switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
NRS115 ªAIRBAGº warning lamp operation
indicates Diagnosis mode.
NRS116 ªAIRBAGº warning lamp operation
indicates User mode.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
lªSELF-DAIG [CURRENT]º
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time. After the malfunction
is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
lªSELF-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.
lªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ªOFFº
for at least 1 second, then back ªONº. Diagnosis mode returns to the User mode. At that time, self-diagno-
sis 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.
