Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

NCS000TH

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.

WARNING:

●

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 for On Board Diagnostic (OBD) System of A/T and Engine

NCS000TI

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 the battery cable from the negative termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid 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 EVAP system or fuel injection system,
etc.

●

Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.

PRECAUTIONS

Precautions

NCS000TJ

●

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.

●

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”.

●

When removing the A/T from a vehicle, do not use the compan-
ion flange section at the rear end of the A/T as a support point.

●

Always use the specified brand of ATF. Refer to

MA-10, "Fluids

and Lubricants"

●

Use lint-free paper not cloth rags during work.

●

After replacing the ATF, dispose of the waste oil using the meth-
ods prescribed by law, ordinance, etc.

●

Before proceeding with disassembly, thoroughly clean the out-
side of the A/T. 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 paper 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 assem-
bly.

●

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 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 A/T fluid cooler if excessive foreign material is found in oil pan or clogging strainer. Refer
to

AT-9, "A/T FLUID COOLER SERVICE"
