PRECAUTIONS
PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" NCS001AN
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 AT
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.
WARNING: D
q 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. E
q 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. F
q 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.
G
Precautions for On Board Diagnostic (OBD) System of A/T and Engine NCS001AO
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. H
CAUTION:
q 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- I
noid valves, etc. Will cause the MIL to light up.
q 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, J
dirt, bent terminals, etc.)
q 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. K
q 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 EVAP system or fuel injection system,
etc. L
q Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.

PRECAUTIONS
Precautions NCS001AP
q Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned OFF.
SEF289H
q After performing each TROUBLE DIAGNOSIS, perform
"DTC (Diagnostic Trouble Code) Confirmation Procedure".
If the repair is completed the DTC should not be displayed
in the "DTC Confirmation Procedure".
SEF217U
q Always use the specified brand of ATF. Refer to MA-12, "Fluids and Lubricants" .
q Use lint-free paper not cloth rags during work.
q After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
q Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.
q Disassembly should be done in a clean work area.
q Use lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
q Place disassembled parts in order for easier and proper assembly.
q All parts should be carefully cleansed with a general purpose, non-flammable solvent before inspection or
reassembly.
q Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
q It is very important to perform functional tests whenever they are indicated.
q 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.
q Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
q 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.
q Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
q After overhaul, refill the transmission with new ATF.
q When the A/T drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque con-
verter 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-12, "Changing A/T Fluid" , AT-13, "Checking A/T Fluid" .

PRECAUTIONS
Service Notice or Precautions NCS001AQ
ATF COOLER SERVICE A
If ATF 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 solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to AT-15, "A/T B
Fluid Cooler Cleaning" . For radiator replacement, refer to CO-14, "RADIATOR" (for VQ35DE), CO-41, "RADI-
ATOR" (for VK45DE).
OBD-II SELF-DIAGNOSIS AT
q 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-92, "SELF-DIAGNOSTIC RESULT MODE" for the indicator used to display each self-diagnostic D
result.
q The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories. E
Always perform the procedure on AT-41, "HOW TO ERASE DTC" to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-53, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" (for VQ35DE) or EC-715,
F
"ON BOARD DIAGNOSTIC (OBD) SYSTEM" (for VK45DE).
q Certain systems and components, especially those related to OBD, may use the new style slide-
locking type harness connector. For description and how to disconnect, refer to PG-71, "HAR-
NESS CONNECTOR" . G
