Disposal of Air Bag Module and Seat Belt Pre-
tensioner
IBefore 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-25).
IWhen deploying the air bag module and seat belt pre-tensioner,
always use the Special Service Tool; Deployment tool
KV99106400.
IWhen deploying the air bag module and seat belt pre-tensioner,
stand at least 5 m (16 ft) away from the deployment component.
IWhen 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.
IAlways activate one air bag module at a time.
IDue 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.
IBe sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
INever apply water to the deployed air bag module and seat belt
pre-tensioner.
IWash your hands clean after finishing work.
IPlace 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.
IUse a voltmeter to make sure the vehicle battery is fully
charged.
IDo not dispose of the air bag module and seat belt pre-ten-
sioner un-deployed.
CHECKING DEPLOYMENT TOOL
Connecting to Battery
IPlace the vehicle outdoors with an open space of at least 6 m
(20 ft) on all sides.
IUse a voltmeter to make sure the vehicle battery is fully
charged.
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.

Trouble Diagnoses Introduction
CAUTION:
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
IDo not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
IKeep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using ªAIR BAGº warning lamp and/or CONSULT-II. The read-
ing 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
NOTE:
Seat belt pre-tensioner malfunction is indicated by ªAIR BAGº warning lamp.
DIAGNOSIS MODE FOR CONSULT-II
IªSELF-DIAG [CURRENT]º
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 requiring
repairs.
IªSELF-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.
IªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
IªECU 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 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.
For NISSAN MODEL R20, the diagnosis sensor unit classification numbers are as follows:
MODEL ECU DISCRIMINATED NO.
Models with single air bag and seat belt pre-tensioner A928
Models with dual air bags and seat belt pre-tensioner A929
Models with dual air bags, side air bag and seat belt pre-tensioner A930
