PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000010152377

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 SR 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 performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR 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 har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery and wait at least three minutes before performing any service.

Precaution for Work

INFOID:0000000009480659

• When removing or disassembling each component, be careful not to damage or deform it. If a component

may be subject to interference, be sure to protect it with a shop cloth.

• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component

with a shop cloth or vinyl tape to protect it.

• Protect the removed parts with a shop cloth and prevent them from being dropped.

• Replace a deformed or damaged clip.

• If a part is specified as a non-reusable part, always replace it with a new one.

• Be sure to tighten bolts and nuts securely to the specified torque.

• After installation is complete, be sure to check that each part works properly.

• Follow the steps below to clean components:

- Water soluble dirt:

• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.

• Then rub with a soft, dry cloth.

- Oily dirt:

• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty

area.

• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.

• Then rub with a soft, dry cloth.

- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.

- For genuine leather seats, use a genuine leather seat cleaner.

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

INFOID:0000000009480660

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 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 mis-connected 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 erase the unnecessary malfunction information (repairs completed) from the TCM and

ECM before returning the vehicle to the customer.

Precaution

INFOID:0000000009480661

• Before connecting or disconnecting the A/T assembly har-

ness connector, turn ignition switch “OFF” and disconnect

negative battery cable. Because battery 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”.

• Always use the specified brand of ATF. Refer to 

MA-16, "FOR USA AND CANADA : Fluids and Lubricants"

(United States and Canada) and 

MA-18, "FOR MEXICO : Fluids and Lubricants"

 (Mexico).

• Use lint-free paper not cloth rags during work.

• After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.

• Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to 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 paper or towels for wiping parts clean. Common shop rags can leave fibers that could interfere

with the operation of the transmission.

• 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.

• Gaskets, seals and O-rings should be replaced any time the transmission 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.

PRECAUTIONS

• 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 

TM-

272, "A/T Fluid Cooler Cleaning"

.

• After overhaul, refill the transmission 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 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

TM-271, "Changing the A/T Fluid (ATF)"

, 

TM-269, "Checking the A/T Fluid (ATF)"

.

Service Notice or Precaution

INFOID:0000000009480662

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 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 

TM-272, "A/

T Fluid Cooler Cleaning"

. For radiator replacement, refer to 

CO-16, "Removal and Installation"

 (QR25DE),

CO-44, "Removal and Installation"

 (VQ40DE).

OBD-II SELF-DIAGNOSIS

• A/T self-diagnosis is performed by the TCM in combination with the ECM. Refer to the table on 

TM-157,

"CONSULT Function (TRANSMISSION)"

 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 memo-

ries.

Always perform the procedure on 

TM-157, "CONSULT Function (TRANSMISSION)"

 to complete the

repair and avoid unnecessary blinking of the MIL.

 For details of OBD-II, refer to 

TM-155, "Introduction"

.

• Certain systems and components, especially those related to OBD, may use the new style slide-lock-

ing type harness connector. For description and how to disconnect, refer to 

PG-74, "Description"

.
