PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “ AIR BAG” and “SEAT BELT PRE-TENSIONER”
ECS00A0J
A
The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIO NER”, 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 includ es 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 Manual.
WARNING:
● To avoid ren dering the SRS ino perative, w hich could inc rease the ris k of personal 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 maintenance, inc luding 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 system. For remo va l of Spiral Cable and Air
Bag Module, see the SRS section.
● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed 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 Engine ECS00A0K
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 ignition switch “OFF” and disconnect the negative battery cable 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 eras e the u nnecess ary mal function i nformatio n (repairs compl eted) from the TC M and
ECM before returning the vehicle to the custom er.

PRECAUTIONS
● 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 pro per assembly.
● 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 co ntains precision p a rts and requires extre me ca re w h en p ar t s 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 be coming scattered or lost .
● Properly installed valves, sle ev e s, plugs, etc. will slide along bores in valve body unde r thei r own we ig 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 over haul, refill the transaxle with new ATF.
● When the A/T drain plug is remove d, only some of t he fluid is drai ned. O ld A/T flu id wil l remain i n torque
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to AT-15, "

POWER TRANSMISSION
“N” position
Since both th e f orward clutch and the direct clut ch are released, torque from the in pu t s h aft dri ve is not transmitted to the output shaft.
“P” position
● The same as for the “N” position, both the forward clutch and the direct clutch are released, so torque
from the input shaft drive is not transmitted to the output shaft.
● The parking pole linked with the selector lever meshes with the parking gear and fastens the output shaft
mechanically.

CAN Communication ECS00A0X
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during opera tion (not independent). In CA N communication, cont rol units are connected with 2
communicatio n lines ( CAN H lin e, CAN L li ne) al lowi ng a high rate of in forma tio n trans missi on wi th less w iring .
Each control unit transmits/receives data but selectively reads required data only.

Line Pressure Control ECS00A0Y
● The pressure control solenoid valve A controls linear line pressure by control signal from TCM and line
pressure for clutches and brakes to reduce shift shock.
● This pressure control solenoid valve A controls the pressure regulator valve as the signal pressure and

LINE PRESSURE CONTROL IS BASED ON THE TCM LINE PRESSURE CHARACTERISTIC PATTERN
In order to obtain the m ost approp riate li ne pressure charac teristic to meet the cu rrent drivi ng state, the TCM
controls the pressure control solenoid valve A current and thus controls the line pressure.
Shift Control ECS00A0Z
The clutch pre ssure control solenoid is c ontrolled by the signals f rom the switches and sensors . Thus, the
clutch pressure is adjusted to be appropriate to th e engine load state and vehicle dri ving state. It becomes

SPECIAL SHIFT MODE
Upslope Mode
When TCM detects upslope from load of engine torque and decrease of acceleration, this mode changes shift
points in high-speed side accordi ng to the upslope degr ee and avoids busy shift of A/T.
Downslope Mode
When TCM detects downsl ope from increase of accelerat ion with accelerator full clos e, this mode operates
moderate engine brake by changing shift points in high-speed side.
Hot Mode Control
This control lowers ATF temperature by changi ng shift points when t he temperature is extre mely high.

In this way, the torque converter clutch piston is not coupled.
Lock-up Applied
● In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
pressure control solenoid valve C and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.

A/T CONTROL SYSTEM
SMOOTH LOCK-UP CONTROL
When shifting fro m the lock -up released state to the lock-up ap plied state, the current ou tput to the pressure
control solenoid valve C is controlled with the TCM. In this way, when shifting to the lock-up applied state, 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 pressure control solenoid valve C is varied to steadily increase the
pressure control solenoid valve C 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 region, the pressure control solenoid valve C current is controlled with the TCM to put it into the
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 both low speed and when the acceler ator has a low
degree of opening.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOSTIC (OBD) SYSTEM PFP:00028 Introduction ECS00A11
The A/T system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination
with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in
the ECM memory but not the TCM memory.
The second is the TCM original self-diagn os is ind ic at ed by th e A/ T CHECK indicator lamp. Th e m alfunction is
stored in the TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For detail,
refer to AT-75, "
SELF-DIAG RESULT MODE" .
OBD-II Function for A/T System ECS00A12
The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system. One function
is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is sent to the
ECM when a mal function occurs in the corre sponding OBD-related part. The other function is to ind icate a
diagnostic result by means of the MIL (malfunction indicator lamp) on the instru ment panel. Sensors, switches
and solenoid valves are used as sensing elements.
The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relation
to A/T system parts.
One or Two Trip Detection Logic of OBD-II ECS00A13
ONE TRIP DETECTION LOGIC
If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored in
the ECM memory as a DTC. The TCM is not provided with such a memory funct ion.
TWO TRIP DETECTION LOGIC
When a malfuncti on is sensed during the fi rst test drive, it is stored in the ECM memory as a 1st trip DT C
(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — 1st Trip
If the same malf unction as that experien ced during the first test drive is sense d during the second te st drive,
the MIL will illuminate. — 2nd Trip
The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
OBD-II Diagnostic Trouble Code (DTC) ECS00A14
HOW TO READ DTC AND 1ST TRIP DTC
DTC and 1st trip DTC can be read by the following methods.
( with CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710 etc.
These DTC are prescribed by SAE J2012.
(CONSULT-II also displays the malfu nctioning component or system.)
● 1st trip DTC No. is the same as DTC No.
● Output of the diagnostic trouble c ode indica tes that the in dicated circ uit has a malfu nction. How-
ever, in case of the Mode II and GST , they do not indicate whether the malfunction is still occurring
or occurred in the past and returned to normal.
CONSULT-II can identify them as shown below, therefore, CONSULT-II (if available) is recommended.
A sample of CONSULT-II display for DTC and 1st trip DTC is shown
on the next page. DTC or 1st trip D TC of a malf unction is displaye d
in SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with CONSULT-II. Time data indicates ho w ma ny ti me s the vehicle wa s driven
after the last detection of a DTC.

Freeze Frame Data and 1st Trip Freeze Frame Data
The ECM has a me mory function, whic h stores the driving c ondition such as fuel s ystem status, calcul ated
load value, engin e coolant temperature, short te rm fuel trim, long term fuel trim, engin e speed and vehicle
speed at the moment the ECM detects a malfunction.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, s tored to gether with t he DTC data, a re call ed freez e fram e data an d disp layed on CO NSULT-II
or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
detail, refer to EC-54, "
FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA" .
Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze fr ame data and it is update d each time a different 1st trip DTC is det ected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. R eme mber, only one set of free ze fra me da ta can be stored in the ECM . The ECM has th e following pri orities to update the data.

Both 1st trip free ze frame data a nd f reeze fr ame data (al ong w ith t he D TC) are clea red w hen the ECM m emory is erased.
HOW TO ERASE DTC
The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOS TIC TEST MODE as
described followi ng .
● If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
● When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode
selector on t he ECM.
The following emi ssion-related diagnostic inf ormation is cleared from the ECM m emory when erasing DTC
related to OBD-II. For details, refer to EC-50, "

How To Perform Trouble Diagnosis For Quick and Accurate Repair ECS00A18
INTRODUCTION
The TCM receives a signal from the vehicle speed signal, throttle position sensor (accelerator pedal position
sensor) or PNP s witch 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 el ements used with the OBD-rel ated parts of the
A/T system for m alfunction-diagno stic purposes. The TCM is capable of diagnosing malfunctioning parts while the ECM can store malfunctions in its memory.
Input and output signals must always be correct and stable in the
operation of th e A/T sy stem. T he A/T system m ust be in good oper ating condition and be free of valve seizure, solenoid valve malfunction, etc.

It is much more difficult to diagnose an error that occurs intermittently rather than co ntinuously. Most inte rmittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking 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 connec ted should be
performed. F o llow the AT-48, "
WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer 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-49
) 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.

with other control units during operation (not independent). In CAN communication, control units are connected with 2 communi cation lines (CA N H line, CAN L line) allowin g a high rate of informa tion transmissio n
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
