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 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
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 number.
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.
Model with dual air bags, side air bag and seat belt pre-tensioner 5A35
Model with dual air bags and side air bag 5A34
Model with dual air bags and seat belt pre-tensioner 5A33
Model with dual air bag5A32
Model with single air bag and pre-tensioner 5A31
Model with single air bag5A30

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 turning ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn igni-
tion 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.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CON-
SULT-II screen in real time. After the malfunction 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.
