LASER BEAM AIMING ADJUSTMENT
Revision: 2004 November 2004 FX35/FX45
LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineAKS006YI
Adjust the laser beam aiming every time the ICC sensor is removed or installed.
CAUTION:

Place the vehicle on the level ground when the laser beam aiming adjustment is operated.

Follow the CONSULT-II when adjusting the Laser beam aiming (Laser beam aiming adjustment
cannot be operated without CONSULT-II).
PreparationAKS006YJ

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.

See that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position).
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 sensor with a soft cloth.
Outline of Adjustment ProcedureAKS006YK
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 automatically adjust the right-left position.).
Setting the ICC Target BoardAKS006YL
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 as shown in the right figure.

2. CAN COMMUNICATION INSPECTION
With CONSULT-II
1. With CONSULT-II self-diagnosis, check that “CAN COMM CIRCUIT” item exists.
OK or NG
OK >> Refer to ACS-41, "DTC 20 CAN COMM CIRCUIT" .
NG >> After replacing combination meter, erase DTC. Perform ICC system running test, and then per-
form self-diagnosis of ICC system again.
Symptom 6: Driving Force Is Hunting.AKS006ZU
1. CHECK ECM
1. Perform self-diagnosis of ECM.
OK or NG
OK >> Refer toACS-63, "Symptom 7: The ICC System Frequently Cannot Detect the Vehicle Ahead/The
Detection Zone Is Short." .
NG >> After repairing applicable parts, erase DTC. Perform ICC system running test, and then perform
self-diagnosis of ICC system again.
Symptom 7: The ICC System Frequently Cannot Detect the Vehicle Ahead/The
Detection Zone Is Short.
AKS006ZV
The detection function may become unstable in the following cases:

When the reflector of the vehicle ahead is deficient/ not clean enough to reflect the radar.

When driving a road with extremely sharp corners.

When the radar cannot detect the reflector of the vehicle ahead as the vehicle ahead is passing a hill or
passing the peak.
1. VISUAL CHECK
1. Check ICC sensor body window for contamination and foreign materials.
OK or NG
OK >> If any contamination or foreign materials are found, remove them. Then perform ICC system run-
ning test.
NG >> GO TO 2.
2. CHECK FUNCTION
1. After adjusting ICC sensor beam aiming, perform ICC system running test. Check that preceding vehicle
detection performance has been improved.
OK or NG
OK >> INSPECTION END
NG >>

Replace ICC sensor, and perform laser beam aiming adjustment.

After performing above. Perform ICC system running test, and then perform self-diagnosis of
ICC system again.
Symptom 8: The System Does Not Detect the Vehicle Ahead at All.AKS006ZW
1. VISUAL CHECK
1. With ignition switch turned ON (engine not started), check that all indicator lamps in ICC system display
are continuously lit. (Check for a missing segment in preceding vehicle detection display.)
OK or NG
OK >> GO TO 2.
NG >> Check for combination meter. Refer to DI-13, "
How to Proceed With Trouble Diagnosis" in DI.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ACS002L3
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 On Board Diagnostic (OBD) System of A/T and EngineACS002L5
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:

Be sure to turn the ignition switch “OFF” and disconnect the battery cable from the negative ter-
minal before any repair or inspection work. The open/short circuit of related switches, sensors,
solenoid valves, etc. will cause the MIL to light up.

Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.

Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.

Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
