PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front sea t belt , helps t o redu ce th e r isk or s everi ty of injury to th e driv er an d front passenge r for c ertain
types of collisi on . Thi s s ys te m in cludes seat belt swi tch inp uts an d dual stage front air bag mod ul es . 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 ne ce ss ary t o se rvi ce th e sy stem saf e ly is i nclu de d in th e SR S and SB se ct i on of th is Ser vic e Manual.
WARNING:
● To avoid rendering the SRS inoperative, which cou ld increase the ris k of personal inju ry or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
● Improper maintenance, in cluding incorrect removal a nd installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For rem ova l of Sp iral Cable and Air
Bag Module, see the SRS section.
● Do not use electrical test equipme nt on any circuit related to the SRS unle ss 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 Service
● Do not look straight into the laser beam discharger when adjusting laser beam aiming.
● Turn the ON/OFF switch OFF during chassis dynamometer testing.
● Do not remove, disassemble, or reposition the ICC sensor unless told to do so.
● Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjusting
laser beam ai ming if necessary.

DESCRIPTION
Outline
The Intelligent Cruise Control (ICC) system automatically maintains a selected distance from the vehicle
ahead accordi ng to that vehicle's speed, or at the set speed, if the road ahe ad is clear.
The ICC func ti o n has t w o cr ui se co ntr o l m odes an d br ak e ass is t (w it h pr e vi ew fu nc tio n) . T h e I CC s yst e m m ay
AUTO-CANCEL for various reasons, for example, when the windshield wipers are operated at the low speed
(LO) or high spee d (HI) position.

EKS007RI
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
Vehicle-to-vehicle distance control mode, the same speed as other vehicles, can be maintained without the
constant need to adjust the operating s peed as with a conventional cruise control sy stem.
The system is intended to enhance the operation of the vehicle when following another vehicle in the same
lane and direction.
If the dist an ce sen sor de tec t s a slow e r mo vi ng ve hi cl e a head , th e syste m w il l r edu ce sp ee d s o th at the ve hi cle
ahead can be followed at the selected distance.
The system automatically controls the throttle and applies the brakes (up to 25% of vehicle braking power) if
necessary.
The detection range of the sensor is approximately 390 ft (120 m) ahead.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Conventional (fixed speed) cr uise control mode is cruising at preset speeds.
Refer to Owner's Manual for Intelligent Cruise Control System operation instructions.
BRAKE ASSIST (WITH PREVIEW FUNCTION)
When the force applied to brake pedal exceeds a certain level, the brake assist is activated and generates a
greater braking force than that of a conventional brake booster, even w ith light pedal force.
When the previe w functi on ident ifies the need to ap ply th e sudden b rake by sensin g the vehic le ahead in the
same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver
depresses the brake pedal and improves brake response by reducing its free play.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
UCS002C1
A
The Supplemental Re straint System such as “AIR BAG” and “SEAT BELT PRE-TENS IONER”, 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 sys tem includes seat belt switch inputs and dual s tage front air bag modules. Th e 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 Manual.
WARNING:
● To avoid rendering the SRS inoperative, which could inc rease the risk of pe rsonal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
● Improper maintenanc e, including incorrect removal and installation of the SRS, can lead to per-
sonal injury ca use d by unintentional ac tiv atio n o f the s ys tem . F or re moval of Spiral C ab le and A ir
Bag Module, see the SRS section.
● Do not use ele ctrical test equipmen t on any c ircuit rela ted to the SRS unless instructed to in th is
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 Engine
UCS002C2
The ECM has an on boa rd diagnos tic system. It wil l light up the m alfunction indicator la mp (MIL) to warn th e
driver of a malfunction causing emission deterioration.
CAUTION:
● Be sure to turn the igni tion switch “OFF” and disconnec t the negative battery cable before an y
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 e rase the unnece ssary m alfunction inform ation (repairs co mpleted) from the TCM and
ECM before returning the vehicle to the custom er.

PRECAUTIONS
Precautions
● Before connecting or disconne cting the A/T assembly har-
ness connector, turn ignition switch “OF F” and disconne ct
negative battery ca ble. Because battery voltage is applied
to TCM even if ignition switch is turned “OFF”.
● After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE”.
If the repair is completed the DTC should n ot be displayed
in the “DTC CONFIRMATION PROCEDURE”.

● Always use the specified brand of ATF. Refer to MA-10, "RECOMMENDED FLUIDS AND LUBRICANTS"
.
● Use paper rags not cloth r a gs during work .
● After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
● Before proceeding with disassembly, thoroughly clean the outside of the transaxle. It is important to pre-
vent the internal parts from becoming contaminated by dirt or other foreign matter.
● Disassembly should be done in a clean work area.
● Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transax le .
● Place disassembled parts in order for easier and proper assembl y.
● All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
● Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
● It is very important to perform functional tests whenever they are indicated.
● The valve bo dy contains prec is io n parts and r eq uir es ex tre me ca re w h en parts ar e r em ov ed and s er v ic ed .
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
● Properly installed valves , sleeves, plugs, etc. w ill slid e alo ng bore s in va lv e bo dy unde r thei r ow n weig ht.
● Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
● Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
● After overh a ul, refill the transaxle with new ATF.
● When the A/T drai n plug is remo ved, on ly some o f the fl uid is d rained. Old A/T fluid w ill remain in torq ue
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Flu id” i n the AT section when changi ng A /T flu id. Ref er

ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solven t and co mpress ed air a fter repair. For A/T fluid cooler cl eani ng proc edu re, refer to AT -14, "
A/T
Fluid Cooler Cleaning" . For radiator replacement, refer to CO-9, "RADIATOR" .
CHECKING AND CHANGING A/T FLUID SERVICE
Increase ATF temperature by 80°C (176°F) once, and then check ATF level in 65°C (149°F) when adjusting
ATF level.
NOTE:
JA60 uses both sys tems of a water-cooling and of an air-co oling. Air-cooling system has a by -pass valve.
When ATF temperature is not over 50°C (122°F) with water-cooling system OFF, it does not flow to air-cooling
system. If ATF level is set without the flow of ATF, the level wil l be 10mm lo wer than the s tandard. Therefor e,
piping should be filled with ATF when adjusting level.
OBD-II SELF-DIAGNOSIS
● A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pa tter n of the mal fun cti on indi cat or la mp (MI L). R efer to the t abl e on AT-92, "
TIC RESULT MODE" for the indicator used to display each self-diagnostic result.
● The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure on AT-39, "
HOW TO ERASE DTC" to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD-II, refer to AT-38, "

1. Inspect the coffee filter for debris.
a. If small metal debris less than 1mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T f luid co oler/radi ator can be re-u sed an d
the procedu re is ended.
b. If one or more pieces of debris are found that are over 1mm
(0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the fluid coo ler is no t service able. The A/T fluid
cooler/radiator must be replaced and the inspection procedure is
ended. Refer to CO-9, "

A/T CONTROL SYSTEM
Line Pressure Control
● When an input torque signal equivalent to the engine drive force is sent from the ECM to the TCM, the
UCS002CH
TCM controls the line pressure solenoid.
● This line pressu re solenoid contro ls the pressur e regulator valve as the signal pre ssure and adjusts t he
pressure of the o perating oil dischar ged from the oil pump to the line pressur e most appropriate to t he
driving state.
PCIA0007E
LINE PRESSURE CONTROL IS BASED ON THE TCM LINE PRESSURE CHARACTERISTIC
PATTERN
● The TCM has s tored in m emory a num ber of patte rns fo r the opti mum li ne p res sure char acteri stic for t he
driving state.
● In order to obtain the mos t appropriate line p ressure characteris tic to meet the curre nt driving state, the
TCM controls the line pressure solenoid cur rent valve and thus controls t he line pressur e.
Normal Control
Each clutch is adjusted to the necessary pressure to match the
engine drive force.
Back-up Control (Engine Brake)
When the select operation is performed during dr iving and the t ransmission is shifted down, the line pressure is set according to the
vehicle speed.
PCIA0008E

A/T CONTROL SYSTEM
During Shift Change
The necessary a nd adequate line pressure for sh ift change is set.
For this reason, line pressure pattern setting corresponds to input
torque and gearshift selection. Also, line pressure characteristic is
set according to engine speed, during engin e brake operati on.

At Low Fluid Temperature
When the A/T fluid temperature drops below the prescribed temperature, in order to speed up the action of each friction element, the line
pressure is set higher than the no rma l lin e pre ss ure char ac te ris tic .
PCIA0011E
Shift Control
The clutch pressure control solenoid is controlled by the signals from the switches and sensors. Thus, the
clutch pressure is adjusted to be appropriate to the engine load state and vehicle driving state. It becomes
possible to finely control the clutch hydraulic pressure with high precision and a smoother shift change characteristic is attained.

Lock-up Control
UCS002CJ
The torque conve rter clutch piston in the torque conv erter is engaged to eliminate torqu e converter slip to
increase power transmission efficiency.
The torque converter clutch control valve operation is controlled by the torque converter clutch solenoid valve,
which is controlled by a signal from TCM, and the torque converter clutch control valve engages or releases
the torque converter clutch piston.

Lock-up Released
● In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the
torque converter clutch solenoid and the lock-up apply pressure is draine d.
In this way, the torque converter clutch piston is not coupled.
AT-34
Page 99
A/T CONTROL SYSTEM
Lock-up Applied
● In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
torque converter clutch solenoid and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.
SMOOTH LOCK-UP CONTROL
When shifting f rom the lock -up releas ed st at e to the lock- up ap plied st ate, the cur rent outp ut to the tor que converter clutch sole noid is controlled with the TCM. In this w ay, when shifting to the lock-up applied s tate, the
torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Half-clutched State
● The current output from the TCM to the torque converter clutch solenoid is varied to gradually increase
the torque con v erter clutch solenoid pressure.
In this way, the lock-up apply pressure gradually rises and while the torque convert er clutch pisto n is put
into half-clutc hed status, the to rque conv erter clutch piston ope rating pres sure is incr eased and the coupling is completed smoothly.
Slip Lock-up Control
● In the slip re gion , the torqu e co nve rter cl utch sole noid current is c ontro lled with the TCM t o put it in to th e
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed.
This raises the fuel efficiency for 4th and 5th gears at bo th low speed and w hen the acceler ator has a low
degree of opening.

Therefore, the low coast brake solenoi d is operated to prevent the forward one-way clutch from idling and
the engine brake is operated in the same manner as conventi onally.
