Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS0046I
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. 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:
●
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.
●
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.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Trouble Diagnosis Precaution
EIS0046J
When you read wiring diagrams, refer to the following:
●

SYSTEM DESCRIPTION
The adjustable pedal system power supply is controlled by pedal adjusting control unit.
Power is supplied at all times
●
through 50A fusible link (letter g , located in the fuse and fusible link box)
●
to circuit breaker-2 terminal 2
●
through circuit breaker-2 terminal 1
●
to pedal adjusting control unit terminal 5.
With the ignition switch in ON or START, power is supplied
●
through 10A fuse [No. 12, located in the fuse block (J/B)]
●
to pedal adjusting control unit terminal 4.
Ground is supplied
●
to pedal adjusting switch terminal 4
●
to pedal adjusting control unit terminal 1
●
through body grounds M57, M61 and M79.
When the A/T selector lever is in P position, ground is supplied
●
to pedal adjusting control unit terminal 3
●
through A/T device terminal 4
●
through A/T device terminal 2
●
through body grounds M57, M61 and M79.
Then pedal adjusting control unit recognizes that A/T selector lever is in P position.
