With CONSULT-II
With “A/T” “DATA MONITOR”, check if “SLCT LVR POSI” operates normally.
OK or NG
OK >> 1. Replace ICC sensor integrated unit, and adjust laser beam aiming.
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
NG >> 1. Perform “A/T” self-diagnosis. Refer to AT- 9 0 , "
CONSULT-II Function (A/T)" .
2. After repairing or replacing applicable item, erase DTC and perform ICC system running test.
Then perform self-diagnosis of ICC system again.
Symptom 5: Chime Does Not SoundNKS004DO
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 pedal.
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-66, "
Symptom 7: ICC
System Frequently Cannot Detect the Vehicle Ahead/ Detection Zone Is Short" ).
1. CHECK ICC WARNING CHIME
With CONSULT-II
With “ICC” “ACTIVE TEST”, check if “ICC BUZZER” operates normally.
OK or NG
OK >> 1. Determine preceding vehicle detection status when malfunction occurred. If chime should have
sounded: after replacing ICC sensor integrated unit and adjust laser beam aiming.
2. Erase DTC and perform ICC system running test, and then perform self-diagnosis of ICC sys-
tem again.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NCS001JC
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.
Precautions for On Board Diagnostic (OBD) System of A/T and EngineNCS001JD
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 termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid 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.

TCM FunctionNCS001JP
The function of the TCM is to:
Receive input signals sent from various switches and sensors.
Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
Send required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The A/T senses vehicle operating conditions through various sensors or signals. It always controls the opti-
mum shift position and reduces shifting and lock-up shocks.

Revision: 2006 January2006 M35/M45
CAN CommunicationNCS001JQ
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. Refer to LAN-34, "
CAN
Communication Unit" .
Input/Output Signal of TCMNCS001JR
*1: Spare for vehicle speed sensorꞏA/T (revolution sensor)
*2: Spare for accelerator pedal position signal
*3: If these input and output signals are different, the TCM triggers the fail-safe function.
*4: Used as a condition for starting self-diagnostics; if self-diagnostics are not started, it is judged that there is some kind of error.
