Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A

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 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:

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.

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.

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.

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. q Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min- SRS
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.

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" .

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 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 collision 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 collision 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" .
