PRECAUTIONS

PFP:00001

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

ABS00DAE

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 Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

5.

Loosen nuts, and remove accelerator pedal assembly.

CAUTION:

●

Before removal and installation accelerator and brake pedals must be in front most position.
This is to align the base position of accelerator and brake pedals (Adjustable type).

●

Do not disassemble accelerator pedal assembly. Do not remove accelerator pedal position sen-
sor from accelerator pedal assembly.

INSPECTION AFTER INSTALLATION

●

Make sure accelerator pedal moves smoothly within the whole operation range when it is fully depressed
and released.

●

Make sure accelerator pedal securely returns to the fully released position.

●

Check operation conditions in forward and rearward movement of accelerator pedal assembly (Adjustable
type). Refer to 

BR-6, "BRAKE PEDAL"

 .

●

For the electrical inspection of accelerator pedal position sensor, refer to 

EC-614, "DTC P2122, P2123

APP SENSOR"

CAUTION:

When harness connector of accelerator pedal position sensor is disconnected, perform “Acceler-
ator Pedal Released Position Learning”. Refer to 

EC-89, "Accelerator Pedal Released Position

AIS002OE

SYSTEM DESCRIPTION

The pedal adjustable system is power supply controlled by pedal adjusting control unit.
Power is at all times supplied

●

through 50A fusible link [Letter F, located in the fuse block (J/B)],

●

to BCM (Body control module) terminal 55.

●

through 10A fuse [No. 18, located in the fuse block (J/B)],

●

through BCM terminal 42,

●

through BCM terminal 54,

●

to pedal adjusting control unit terminal 5.

●

through 10A fuse [No. 21 (without intelligent key) or No. 22 (with intelligent key), located in the fuse block
(J/B)],

●

to key switch terminal 3.

With ignition key inserted, power is supplied

●

through key switch terminal 4,

●

to CVT device terminal 5.

With the ignition switch to ON position, power is supplied

●

through 10A fuse [No. 12, located in the fuse block (J/B)],
