PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EIS004GT

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:
G 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.
G 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.
G 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.

SYSTEM DESCRIPTION
The adjustable pedal system power supply is controlled by pedal adjusting control unit.
Power is supplied at all times
G through 50A fusible link (letter f , located in the fuse and fusible link box)
G to circuit breaker-2 terminal 2
G through circuit breaker-2 terminal 1
G to pedal adjusting control unit terminal 5, and
G through 10A fuse [No. 19, located in the fuse block (J/B)]
G to key switch and key lock solenoid terminal 3 (with floor shift).
With the ignition switch in ON or START position, power is supplied
G through 10A fuse [No. 12, located in the fuse block (J/B)],
G to pedal adjusting control unit terminal 4.

G to pedal adjusting control unit terminal 3
G through A/T device terminal 6
G through A/T device terminal 5
G from key switch and key lock solenoid terminal 4.
Then pedal adjusting control unit recognizes that A/T selector lever is in P position.
With the ignition switch in OFF or ON position and A/T selector lever is shifted to the P position, power is sup-
plied
G through pedal adjusting control unit terminal 7
G to pedal adjusting switch terminal 1.
With power supplied, pedal adjusting switch is energized.

G to pedal adjusting motor terminal +.
Ground is supplied
G to pedal adjusting motor terminal -
G through pedal adjusting switch terminal 2
G through pedal adjusting switch terminal 4
G through body grounds M57, M61 and M79.
With power and ground supplied, accelerator and brake pedals move forward.
When pedal is adjusted backward, power is supplied
G through pedal adjusting switch terminal 2
G to pedal adjusting motor terminal -.
Ground is supplied
G to pedal adjusting motor terminal +
G through pedal adjusting switch terminal 3
G through pedal adjusting switch terminal 4
G through body grounds M57, M61 and M79.
