PRECAUTIONS

PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EHS000LM

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING: D
q 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 per-
formed by an authorized NISSAN/INFINITI dealer. E
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section. F
q 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 and/or orange harnesses or
harness connectors.
G
Precautions for SRS "Air Bag" and "Seat Belt Pre-tensioner" Service EHS000IH

q Do not use a circuit tester to check SRS circuits unless instructed to in this Service Manual.
SRS
q Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bags and seat belt
pre-tensioners to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes I
have passed.
q Air bag diagnosis sensor unit must always be installed with forward mark "" pointing toward the front of
the vehicle for proper operation. Also check air bag diagnosis sensor unit for deformities, dents, cracks J
and rust before installation and replace as required.
q The spiral cable must be aligned in the neutral position since its rotations are limited. Do not rotate steer-
ing column while steering gear is removed to avoid damaging spiral cable. K
q Handle air bag module carefully. Always place it with air bag lid surface facing upward.
q Conduct self-diagnosis to check entire SRS for proper function after replacing any components. Refer to
SRS-18, "SRS Operation Check" . L
q After air bag inflates, the instrument panel assembly should be replaced if damaged.

SRS-3
PRECAUTIONS

After A Collision EHS000II

WARNING:
Inspect all seat belt assemblies including retractors, buckles and attaching hardware after any colli-
sion.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt assemblies
which are equipped with pre-tensioners should be replaced even if the seat belts are not in use during
a frontal collision in which the air bags are deployed.
Replace any seat belt assembly (including anchor bolts) if:
q The seat belt was in use at the time of a collision (except after minor collisions when the belts, retractors
and buckles show no damage and continue to operate properly).
q The seat belt was damaged in an accident (i.e., torn webbing, bent retractor or guide, etc.).
q The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
q Anchor bolts are deformed or worn out.
q The seat belt assembly is equipped with a pre-tensioner, even if the seat belt is not in use during a colli-
sion in which the air bags are deployed.
Wiring Diagrams and Trouble Diagnosis EHS000IJ

When you read wiring diagrams, refer to the following:
q Refer to GI-13, "How to Read Wiring Diagrams" .
q Refer to PG-8, "POWER SUPPLY ROUTING" for power distribution circuit.
When you perform trouble diagnosis, refer to the following:
q Refer to GI-9, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
q Refer to GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident" .

Trouble Diagnoses Introduction EHS000IW

CAUTION:
q 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 connectors.
q Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
q Keep ground portion clean.
DIAGNOSIS FUNCTION
The 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 mal-
function 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-II
q "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.
q "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.
q "TROUBLE DIAG RECORD"
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.
q "ECU DISCRIMINATED NO."
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. 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.

SRS

SRS804

HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II J
From User Mode to Diagnosis Mode
Diagnosis mode activates only when a malfunction is detected, by turning ignition switch as follows:
1. Turn ignition switch "ON". K
2. After "AIR BAG" warning lamp lights for 7 seconds, turn ignition switch "OFF" within 1 second.
3. Wait more than 3 seconds.
L
4. Repeat steps 1 to 3 three times.
5. Turn ignition switch "ON".
SRS will not enter Diagnosis mode, if no malfunction is detected. M
From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition "OFF" for at least one second, then back "ON". Diagnosis
mode is returned to User mode.
If switching Diagnosis mode to User mode is required while malfunction is being detected, by turning ignition
switch as follows:
1. Turn ignition switch "ON".
2. After "AIR BAG" warning lamp lights for 7 seconds, turn ignition switch "OFF" within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 three times.
5. Turn ignition switch "ON".
HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
q "SELF-DIAG [CURRENT]"
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time.

SRS-9
TROUBLE DIAGNOSIS

After the malfunction is repaired completely, no malfunction is detected on "SELF-DIAG [CURRENT]".
q "SELF-DIAG [PAST]"
Return to the "SELF-DIAG [CURRENT]" CONSULT-II screen by pushing "BACK" key of CONSULT-II and
select "SELF-DIAG [CURRENT]" in SELECT DIAG MODE. Touch "ERASE" in "SELF-DIAG [CURRENT]"
mode.
NOTE:
If the memory of the malfunction in "SELF-DIAG [PAST]" is not erased, the User mode shows the
system malfunction by the operation of the warning lamp even if the malfunction is repaired com-
pletely.

q "TROUBLE DIAG RECORD"
The memory of "TROUBLE DIAG RECORD" cannot be erased.

SRS701

Without CONSULT-II
After a malfunction is repaired, switch the ignition "OFF" for at least one second, then back "ON". Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.
