PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ABS00A37
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.

Precautions for ICC System ServiceAKS006Y8

Do not look straight into the laser beam discharger when adjusting laser beam aiming.

Turn the ON/OFF switch OFF in conditions similar to driving, suchlike Free rollers or Chassis dynamome-
ter.

Do not use the ICC sensor removing from vehicle, disassemble, or remodel the sensor.

Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjusting
laser beam aiming if necessary.

TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2004 November 2004 FX35/FX45
Symptom 4: The ICC System Is Not Cancelled When the Gear Is in Other Than
‘D’.
AKS006ZR
1. CHECK D RANGE SWITCH
With CONSULT-II
1. With data monitor, check that “D RANGE SW” operates normally.Refer to ACS-32, "
DATA MONITOR" .
OK or NG
OK >> After replacing ICC unit, erase DTC. Perform ICC system running test, and then perform self-diag-
nosis of ICC system again.
NG >> GO TO 2.
2. CHECK CAN COMMUNICATION
With CONSULT-II
1. With CONSULT-II self-diagnosis, check that “CAN COMM CIRCUIT” item exists.
OK or NG
OK >> GO TO 3.
NG >> Refer to ACS-41, "
DTC 20 CAN COMM CIRCUIT" .
3. CHECK D RANGE SWITCH
1. With TCM data monitor, check that “D” position switch operates normally.
OK or NG
OK >> After replacing ICC unit. Perform ICC system running test, and then perform self-diagnosis of ICC
system again.
NG >> After repairing or replacing malfunctioning part. Perform ICC system running test, and then per-
form self-diagnosis of ICC system again.
Symptom 5: Chime Does Not Sound.AKS006ZS
The chime may not sound occasionally in the following cases even if the distance from the vehicle ahead is
short:

When the speed difference from that of the vehicle ahead is small (both vehicles driving at similar speed).

When the vehicle ahead drives at faster speed (the actual distance is increasing).

When depressing the accelerator.

Chime does not sound when the vehicle is not driving.

Chime does not sound when the system does not detect any vehicle ahead. (Diagnose the conditions
under which the system is detecting the vehicle ahead and when the system is malfunctioning. If there is
any malfunction in detecting the vehicle ahead, check the system following the ACS-63, "
Symptom 7: The
ICC System Frequently Cannot Detect the Vehicle Ahead/The Detection Zone Is Short." .
1. CHECK ICC WARNING CHIME
With CONSULT-II
1. With active test, check that ICC warning chime operates normally.
OK or NG
OK >> Determine preceding vehicle detection status when malfunction occurred. If chime should have
sounded: after replacing ICC unit. Perform ICC system running test, and then perform self-diag-
nosis of ICC system again.
NG >> GO TO 2.
