Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NBS005RO
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.
WAR NING :
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.

INSTALLATION
Installation is the reverse order of removal.
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.
For the electrical inspection of accelerator pedal position sensor, refer to the following.
–VQ35DE
EC-626, "
DTC P2122, P2123 APP SENSOR".
–VK45DE
EC-1358, "
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-95, "
Accelerator Pedal Released Position
Learning" (VQ35DE) or EC-806, "Accelerator Pedal Released Position Learning" (VK45DE).

LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineNKS004CM
Adjust the laser beam aiming every time the ICC sensor integrated unit is removed or installed.
CAUTION:
Adjust laser beam aiming at a horizontal place as far as 12 m (39 ft) forward the vehicle can be
seen.
Adjust laser beam aiming 5 seconds after starting engine.
Never view ICC sensor integrated unit body window directly during laser beam aiming adjustment.
Follow the CONSULT-II when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-II).
Never ride on vehicle during laser beam aiming adjustment.
Idle and turn headlamps OFF during laser beam aiming adjustment.
PreparationNKS004CN
Adjust the tire pressure to the specified value.
See that there is no load in the vehicle.
Coolant, engine oil filled up to correct level and full fuel tank.
Shift the gear into “P” position and release the parking brake.
Clean the ICC sensor integrated unit with a soft cloth.
Remove the front bumper grille. Refer to EI-13, "Removal and
Installation of Front Bumper Grille" .
Outline of Adjustment ProcedureNKS004CO
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSULT-II. (Turn manually the screw for up-down position
adjustment. ICC sensor integrated unit automatically adjust the right-left position.)
Setting the ICC Target BoardNKS004CP
Accurate ICC target board setting is required for the laser beam aiming adjustment.
CAUTION:
ICC system does not function normally if laser beam aiming is not accurate.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale at 28 mm (1.10 in) below the center.

6. Touch “LASER BEAM ADJUST”.
7. Touch “START”.
CAUTION:
If the adjustment screen does not appear on the CONSULT-
II screen in 10 seconds. After touching “LASER BEAM
ADJUST” screen, the following causes may be considered:
Target is not set accurately.
There is not enough space beside the target.
The range of laser beam aiming exceeds for improper
installation position.
–Deformation of vehicle body.
–Deformation of unit.
–Deformation of bracket.
The area is not suitable for the adjustment work.
ICC sensor integrated unit is not clean.
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the up-down direction adjusting
screw until “U/D CORRECT” value is set in the range of
4.
CAUTION:
Turn the screw slowly. The value change on display is
slower than actual movement of the ICC sensor integrated
unit. Wait for 2 seconds every time the screw is turned half
a rotation.
NOTE:
Turning the screw clockwise to laser beam is downward and
counterclockwise to laser beam is upward.
9. When “U/D CORRECT” value indicates
4, confirm that the margin of value remains within 4 at least for
2 seconds with no equipment or hand touching the ICC sensor integrated unit.
