3. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left about 2.5
revolutions from the right end position. Align the two marks
(
,
m).
CAUTION:
The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable may
snap by turning the steering wheel beyond the limited num-
ber of turns.
The spiral cable can be turned up to about 2.5 turns from the
neutral position to both the right and left.
4. Connect spiral cable connector and tighten with screws.
Install steering column cover.
5. Install steering wheel, setting spiral cable pin guide, and pull
spiral cable through.
6. Connect horn connector and engage spiral cable with pawls
in steering wheel. Move air bag module connector away from
steering wheel lower lid opening.
7. Tighten nut.

8. Install dynamic damper.
9. Position air bag module and tighten with new special bolts.
+Always service the air bag module from the side.
10. Connect air bag module connector.
11. Install steering switches and lids.
12. Perform self-diagnosis to ensure entire SRS operates prop-
erly. (Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery
cables.
13. Turn steering wheel to the left end and then to the right end
fully to make sure that spiral cable is set in the neutral posi-
tion.
If air bag warning lamp blinks or stays ON (at the User
mode), it shows the spiral cable may be snapped due to its
improper position. Perform self-diagnosis again (use CON-
SULT-II or warning lamp). If a malfunction is detected,
replace the spiral cable with a new one.
14. Perform self-diagnosis again to check that no malfunction is
detected.

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-2013).
+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.

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 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.
