DISPOSING OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER
NJRS0022S04Deployed air bag module and seat belt pre-tensioner 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
reused.
Wash your hands clean after finishing work.

Trouble Diagnoses Introduction=NJRS0043CAUTION:
Do not use electrical test equipment on any circuit related to the SRS 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 FUNCTIONNJRS0043S01The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes — “User mode” and“Diagnosis mode”.
The User mode is exclusively prepared for the customer (driver). This modewarns 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-II are as follows:
User mode Diagnosis mode Display type
“AIR BAG” warning lamp X X ON-OFF operation
CONSULT-II — X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.
DIAGNOSIS MODE FOR CONSULT-IINJRS0043S02“SELF-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 requiring
repairs.
“SELF-DIAG [PAST]”
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.
“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber. This number will be displayed on the CONSULT-II screen, as shown below. When replacing the diag-
nosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a cor-
rect unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL N16, the diagnosis sensor unit classification numbers are as follows:
DESTINATION MODEL ECU DISCRIMINATED NO.
