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
Precautions for A/T Assembly or TCM Replacement ECS00A0L
● When replacing A/T assembly or TCM, refer to the pattern table below and initialize TCM if necessary.
TCM INITIALIZATION PATTERNS
TCM A/T assembly Erasing EEPROM in TCM Remarks
Replaced with
new one
Not replaced
Replaced with
old one
NOTE:
“Old one” is the TCM or A/T assembly that has been used on other vehicles.
METHOD FOR TCM INITIALIZATION
1. Perform “CONSULT-II SETTING PROCEDURE”. Refer to AT-75, "CONSULT-II SETTING PROCEDURE"
.
2. Set the vehicle following the items listed below.
● Ignition switch “ON”.
● Selector lever “P” or “N” position.
● Engine not running.
● Vehicle speed is 0 km/h (0 MPH).
● Ignition voltage is more than 10.5V.
● Malfunction was not detected.
3. Touch “WORK SUPPORT”.
4. Touch “INITIALIZATION”.
5. Initialize TCM following the direction in display.
Not replaced
Replaced with
new or old one

Not required
Required
Not required because the EEPROM in TCM is in the default
state.
Required because data cannot be conformed to previ ous
data written in the EEPROM in TCM.

PRECAUTIONS
Precautions ECS00A0M
● Before connecting or dis connecting the TCM harness con-
nector, turn ignition switch “OFF” and d isconnect ne gative
battery cable. Because battery voltage is applied to TCM
even if ignition switch is turned “OFF”.

● When connecting or disconnecting pin connectors i nto or
from TCM, take care not to dama ge pin terminals (bend or
break).
Make sure that there are not any ben ds or breaks on TCM
pin terminal, when connecting pin connectors.
● Before replacing TCM, perform TCM input/output signal
inspection and make sure wheth er TCM functions properly
or not. AT-72, "
TCM INSPECTION TABLE".

● After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE”.
The DTC should not be displ ayed in the “DTC CONFIRMATION PROCEDURE” if the repair is completed.
SEF217U
● Always use the specified brand of A/T fluid. Refer to MA-9, "Fluids and Lubricants" .
● Use paper ra gs not cloth rags during work.
● After replacing the A/T fluid, dispose of the waste oil using the method s prescribed by law, ordinance, etc.
● Before proceed ing with dis assemb ly, thoroughly clean the outsid e of the tran saxle. It is important t o 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 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, "
Changing A/T Fluid" , AT-15, "Checking A/T Fluid" .

PRECAUTIONS
Service Notice or Precautions ECS00A0N
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 cl ean the A/T oil c ooler mounted in the radiator or replace the radi ator. Flush cooler lines us ing
cleaning solvent and compressed air after repair. Check Service Bulletins for latest A/T oil cooler cleaning procedure. For radiator replacement, refer to CO-12, "
RADIATOR" .
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 pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table
on AT-75, "
● 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-41, "
unnecessary blinking of the MIL.
● For details of OBD-II, refer to EC-49, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
● Certain systems and com ponents, especially those related to OBD , may use the n ew style slide-
locking type harness connector. For description and how to disconnect, refer to PG-62, "

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.
