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 minutes.
2. Disconnect air bag modules and seat belt pre-tensioners con-
nector.
3. Connect deployment tool (SST: KV99106400) to air bag mod-
ule or seat belt pre-tensioner.
For front passenger air bag module and seat belt pre-tensioner,
attach deployment tool adapter (SST: KV99108300 and
KV999R0020) to the tool connector.
4. Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
5. The lamp on the right side of the tool, marked ``deployment tool
power'', should glow green, not red.
6. Press the button on the deployment tool. The left side lamp on
the tool, marked ``air bag connector voltage'', will illuminate and
the air bag module or seat belt pre-tensioner will deploy.
CAUTION:
Activate only one passenger 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 cannot be re-
used.
+Wash your hands clean after ®nishing work.

Trouble Diagnoses Introduction
CAUTION:
+Do not use a circuit tester to check SRS harness connectors unless instructed to in this Service
Manual. SRS wiring harnesses except for ``SEAT BELT PRE-TENSIONER'' can be identi®ed with
yellow harness protector or yellow 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 ``AIR BAG'' warning lamp and/or CONSULT.
System Using CONSULT Using warning lamp
Seat belt pre-tensioner X Ð
Air bag Driver air bag X X
Front passenger air bag X X
The reading of these results is accomplished using one of two modes Ð ``User mode'' and ``Diagnosis mode''.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the ``AIR BAG'' warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the ``AIR BAG'' warning lamp and CONSULT are as follows:
User mode Diagnosis mode Display type
``AIR BAG'' warning lamp X X ON-OFF operation
CONSULT Ð X Monitoring
DIAGNOSIS MODE FOR CONSULT
+``SELF-DIAG [CURRENT]''
A current Self-diagnosis result (also indicated by the warning lamp ¯ashes in the Diagnosis mode) is dis-
played on the CONSULT screen in real time. This refers to a malfunctioning part requiring repairs.
+``SELF-DIAG [PAST]''
Diagnosis results previously stored in the memory are displayed on the CONSULT screen. The stored
results are not erased until memory erasing is executed.
+``TROUBLE DIAG RECORD''
With ``TROUBLE DIAG RECORD'', diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT screen.
+``ECU DISCRIMINATED NO.''
The diagnosis sensor unit for each vehicle model is assigned
with its own, individual classi®cation number. This number will
be displayed on the CONSULT 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 con®rming this classi®cation number on
the CONSULT screen.
For NISSAN MODEL Y61, the diagnosis sensor unit classi®ca-
tion numbers assigned are C2 (Hardtop models) and 27 (Mod-
els except Hardtop).

HOW TO CHANGE SELF-DIAGNOSIS MODE
With CONSULT
From User mode to Diagnosis mode
After selecting AIR BAG on the ``SELECT SYSTEM'' screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis mode to User mode
To return to User mode from diagnosis mode, touch ``BACK'' key of CONSULT until ``SELECT SYSTEM''
appears. Diagnosis mode automatically changes to User mode.
Without CONSULT
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 ``ON''. 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 ``OFF'' for at least 1 second, then back ``ON''. Diagnosis
mode returns to User mode. If switching from Diagnosis mode to User mode is required while malfunction is
being detected, switch the ignition ``OFF'', then back ``ON'' and press the driver's door switch at least 5 times
within 7 seconds.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT
+``SELF-DIAG [CURRENT]''
A current Self-diagnosis result is displayed on the CONSULT screen in real time. After the malfunction is
repaired completely, no malfunction is detected on ``SELF-DIAG [CURRENT]''.
+``SELF-DIAG [PAST]''
Return to the ``SELF-DIAG [CURRENT]'' CONSULT screen by
pushing ``BACK'' key of CONSULT and select ``SELF-DIAG
[CURRENT]'' in ``SELECT DIAG MODE''. Touch ``ERASE'' in
``SELF-DIAG [CURRENT]'' mode.
NOTE:
If the memory of the malfunction in ``SELF-DIAG [PAST]'' is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is
repaired completely.
+``TROUBLE DIAG RECORD''
The memory of ``TROUBLE DIAG RECORD'' cannot be erased.
Without CONSULT
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ``OFF'' for
at least 1 second, then back ``ON''. At that time, the problem code 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 problem. It is important to fully understand the symptoms
or conditions for a customer complaint.
