PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
UCS006XG
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.
WA RN ING:
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 Necessary for Steering Wheel Rotation After Battery DisconnectUCS006XH
NOTE:
This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

Precautions for On Board Diagnostic (OBD) System of A/T and EngineUCS005M 2
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 battery negative cable from battery nega-
tive terminal before any repair or inspection work. The open/short circuit of related switches, sen-
sors, 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 connectors are 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 erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionsUCS005M 3
Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect the battery
cable from the negative terminal. Failure to do so may dam-
age the TCM. Because battery voltage is applied to TCM
even if ignition switch is turned off.
When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. (See page AT- 7 8 , "
TCM Terminals and Reference
Va l u e".)
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
The DTC should not be displayed in the “DTC Confirmation
Procedure” if the repair is completed.
Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent 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 A/T.
Place disassembled parts in order for easier and proper assembly.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Revision: June 20062007 Versa
Gaskets, seals and O-rings should be replaced any time the A/T is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
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. will slide along bores in valve body under their own weight.
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.
Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
Refer to .
After overhaul, refill the A/T with new ATF.
When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in 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 - 1 7 , "
Changing A/T Fluid" , AT- 1 6 , "Checking A/T Fluid" .
Service Notice or PrecautionsUCS005M4
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 oil cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. Check Service Bulletins for latest A/T oil cooler cleaning pro-
cedure. For radiator replacement, refer to Refer to CO-11, "
RADIATOR" .
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
External leaks in the hub weld area.
Converter hub is scored or damaged.
Converter pilot is broken, damaged or fits poorly into crankshaft.
Steel particles are found after flushing the cooler and cooler lines.
Pump is damaged or steel particles are found in the converter.
Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)
Converter is contaminated with engine coolant containing antifreeze.
Internal malfunction of stator roller clutch.
Heavy clutch debris due to overheating (blue converter).
Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
The threads in one or more of the converter bolt holes are damaged.
A/T malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.

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 OD OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the
table on AT- 9 1 , "
Judgement of Self-diagnosis Code" 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 “HOW TO ERASE DTC” on AT-40, "
HOW TO ERASE DTC" to com-
plete the repair and avoid unnecessary blinking of the MIL.
The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the OD OFF indicator lamp does not indicate any malfunctions.
–PNP switch
–A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of OBD-II, refer to AT- 3 9 , "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
Certain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector.
For description and how to disconnect, refer to PG-68, "
