PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS002UK
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.

STARTING SYSTEM
Revision: 2006 December 2006 FX35/FX45
STARTING SYSTEMPFP:23300
System Description NKS002UQ
Power is supplied at all times

through 40A fusible link (letter F, located in the fuse and fusible link block)

to ignition switch terminal 1,

through 15A fuse (No. 78, located in the IPDM E/R)

to CPU of IPDM E/R,

through 10A fuse (No. 71, located in the IPDM E/R)

to CPU of IPDM E/R.
When the selector lever in the P or N position, power is supplied

from TCM, and through A/T assembly terminal 9

to IPDM E/R terminal 53.
Ground is supplied

to IPDM E/R terminals 38, 50 and 60

from grounds E21, E50 and E51.
With the ignition switch in the START position, and provided that the IPDM E/R receives a starter relay ON sig-
nal from the CAN lines, the IPDM E/R is energized and power is supplied

from ignition switch terminal 5

to IPDM E/R terminal 4 and

through IPDM E/R terminal 3

to starter motor terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
