Precautions for Supplemental Restraint System
(SRS) ªAIR BAGº and ªSEAT BELT
PRE-TENSIONERº
NCAT0002The 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:
ITo 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.
IImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except ªSEAT BELT PRE-TENSIONERº connector) can be
identified with yellow harness connector (and with yellow harness protector or yellow insulation
tape before the harness connectors).
Precautions for On Board Diagnostic (OBD)
System of CVT and Engine
NCAT0198The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver
of a malfunction causing emission deterioration.
CAUTION:
IBe sure to turn the ignition switch ªOFFº and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc.
will cause the MI to light up.
IBe sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
IBe sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MI to light up due to a short circuit.
IBe sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to a malfunction of the EGR system or fuel injection system, etc.
IBe sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionsNCAT0003IBefore connecting or disconnecting the TCM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the
TCM. Because battery voltage is applied to TCM even if
ignition switch is turned off.

HOW TO ERASE DTC (WITH GST)NCAT0020S041. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªOBD SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC section ªGeneric Scan Tool (GST)º.
HOW TO ERASE DTC (NO TOOLS)NCAT0020S051. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-25. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
Refer to EC section ªHOW TO SWITCH DIAGNOSTIC TEST MODESº.
Malfunction Indicator (MI)NCAT00211. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
IIf the malfunction indicator does not light up, refer to EL sec-
tion (ªWarning Lamps/System Descriptionº, ªWARNING
LAMPS AND CHIMEº).
(Or see MI & Data Link Connectors in EC section.)
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (OBD) malfunction. For detail,
refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM
DESCRIPTIONº).
CONSULT-IINCAT0022After performing ªSELF-DIAGNOSTIC PROCEDURE (WITH CON-
SULT-II)º (AT-19), place check marks for results on the ªDIAGNOS-
TIC WORKSHEETº, AT-31. Reference pages are provided follow-
ing the items.
NOTICE:
IAdditional CONSULT-II information can be found in the Opera-
tion Manual supplied with the CONSULT-II unit.
