PRECAUTIONS
Revision: 2005 July 2005 FX
[ICC]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS00FCX
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 ServiceAKS00C88

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

Turn the MAIN switch OFF in conditions similar to driving, such like Free rollers or a 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: 2005 July 2005 FX
Symptom 4: ICC System Is Not Cancelled When the Gear Is in Other Than “D”AKS00C9C
1. CHECK D RANGE SWITCH
With CONSULT-II
With “DATA MONITOR”, check that “D RANGE SW” operates normally. Refer to ACS-32, "
DATA MONITOR" .
OK or NG
OK >> 1. Replace ICC unit. 2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system again.
NG >> GO TO 2.
2. CHECK ICC UNIT SELF-DIAGNOSIS
With CONSULT-II
1. Perform self-diagnosis with CONSULT-II.
2. Check if “DTC 20 CAN COMM CIRCUIT” is indicated.
Is it indicated?
YES >> Refer to ACS-43, "DTC 20 CAN COMM CIRCUIT" .
NO >> GO TO 3.
3. CHECK D RANGE SWITCH
With TCM “DATA MONITOR”, check that “D” position switch operates normally.
OK or NG
OK >> 1. Replace ICC unit. 2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system again.
NG >> 1. Repair or replace applicable item. 2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system again.
Symptom 5: Chime Does Not SoundAKS006ZS
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-69, "
Symptom 7: ICC
System Frequently Cannot Detect the Vehicle Ahead/ Detection Zone Is Short" .
1. CHECK ICC WARNING CHIME
With CONSULT-II
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.

A/T FLUID
Revision: 2005 July 2005 FX
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

To check A/T fluid level, insert the A/T fluid level gauge
until the cap contacts the end of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.

If ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-14,
"RADIATOR" (for VQ35DE) or CO-41, "RADIATOR" (for
VK45DE) and AT- 1 5 , "
A/T Fluid Cooler Cleaning" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
10. Tighten level gauge bolt.
Level gauge bolt: : 5.1 N·m (0.52 kg-m, 45 in-lb)

How to Perform Trouble Diagnosis for Quick and Accurate RepairACS002LU
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelerator pedal position sensor (throttle position
sensor) or PNP switch and provides shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose a error that occurs intermittently
rather than continuously. Most intermittent errors are caused by poor
electric connections or improper wiring. In this case, careful check-
ing of suspected circuits may help prevent the replacement of good
parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II (or GST) or a circuit tester connected should be
performed. Follow the AT- 4 6 , "
WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSHEET” as
shown on the example (Refer to AT- 4 7
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
