Precautions for Supplemental Restraint System
(SRS) ªAIR BAGº and ªSEAT BELT
PRE-TENSIONERº
NLEC1263The Supplemental Restraint System ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº, used along with a seat
belt, help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The
Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable.
In addition to the supplemental air bag modules for a frontal collision, the supplemental side air bag used along
with the seat belt helps to reduce the risk or severity of injury to the driver and front passenger in a side col-
lision. The supplemental side air bag consists of air bag modules (located in the outer side of front seats),
satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal collision),
wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision). Information
necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
+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 with yellow harness connector (and with
yellow harness protector or yellow insulation tape before the harness connectors).
SEF706Y
Engine Fuel & Emission Control SystemNLEC0602+Always use a 12 volt battery as power source.
+Do not attempt to disconnect battery cable while engine is
running.
+Before connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the
ECM because battery voltage is applied to ECM even if
ignition switch is turned off.
+Before removing parts, turn off ignition switch and then
disconnect battery ground cable.
SEC220B
+Do not disassemble ECM.
+If a battery terminal is disconnected, the memory will
return to the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is
disconnected. However, this is not an indication of a prob-
lem. Do not replace parts because of a slight variation.

Trouble Diagnoses Introduction=NLRS0043CAUTION:
+Do 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.
+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 FUNCTIONNLRS0043S01The 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 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-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-IINLRS0043S02+“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 (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 V10, the diagnosis sensor unit classification numbers are as follows:
MODEL ECU DISCRIMINATED NO.
Models with single air bag and seat belt pre-tensioner A910
Models with dual air bags and seat belt pre-tensioner A911
Models with dual air bags, side air bag and seat belt pre-tensioner A912

3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-55, and repair mal-
functioning part completely.
6. Turn ignition switch“ON”.“AIR BAG”warning lamp operates in
User mode. Compare“AIR BAG”warning lamp operation to
the chart on the next page
NOTE:
When a malfunction is detected, switch from Diagnosis mode to
user mode by turning the ignition switch as follows:
1) Turn ignition switch“ON”.
2) After“AIR BAG”warning lamp lights for 7 seconds, turn igni-
tion switch“OFF”within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch“ON”.
