Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001366680
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
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. Information necessary to service the system safely is included in the SR and SB section of
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/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
 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 har-
ness connectors.
Precaution for Seat Belt ServiceINFOID:0000000001366681
CAUTION:
 Before removing the front seat belt pre-tensioner assembly, turn the ignition switch off, disconnect
the both battery cables and wait at least 3 minutes.
 After replacing or reinstalling front seat belt pre-tensioner assembly, or reconnecting front seat belt
pre-tensioner connector, check the system function. Refer to SRC-11, "
SRS Operation Check".
 Do not disassemble buckle or seat belt assembly.
 Do not reuse seat belt anchor bolts after removal. Replace with new ones.
 Replace anchor bolts if they are deformed or worn out.
 Never oil tongue and buckle.
 If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
 If webbing is cut, frayed, or damaged, replace seat belt assembly.
 When replacing seat belt assembly, use a genuine NISSAN seat belt assembly.
AFTER A COLLISION
WARNING:
 Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
 NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the
collision 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 pre-tensioner
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:
 The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
 The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide).
 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.
 Anchor bolts are deformed or worn out.
 The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.

Ignition relay malfunction detection function
 IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
 IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
 If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
