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 AIRBAG” and “SEAT BELT” of this
Service Manual.

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 “SRS AIRBAG”.

• 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.

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

INFOID:0000000003130581

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 terminal

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 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.

General Precautions

INFOID:0000000003130582

• Turn ignition switch OFF and disconnect the battery cable

from the negative terminal before connecting or disconnect-
ing the A/T assembly harness connector. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.

PRECAUTIONS

• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION

PROCEDURE” after performing each TROUBLE DIAGNOSIS.
If the repair is completed DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.

• Always use the specified brand of ATF. Refer to

MA-10, "Fluids

and Lubricants"

• Use lint-free paper not cloth rags during work.
• Dispose of the waste oil using the methods prescribed by law, ordi-

nance, etc. after replacing the ATF.

• 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.

• 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 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

TM-

138, "Service Notice or Precaution"

• Refill the transmission with new ATF after overhaul.
• 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 “Inspection” and “Changing” when changing ATF. Refer to

TM-141,

"Inspection"

TM-142, "Changing"

Service Notice or Precaution

INFOID:0000000003130583

ATF COOLER SERVICE

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

TM-143,

"Cleaning"

. For radiator replacement, refer to

CO-13, "Exploded View"

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 lamp or the malfunction indicator lamp (MIL). Refer to the
table on “SELF-DIAGNOSTIC RESULTS” for the indicator used to display each self-diagnostic result. Refer
to

TM-40, "CONSULT-III Function (TRANSMISSION)"

• The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memo-

ries.
Always perform the procedure on “How to Erase DTC” to complete the repair and avoid unnecessary
blinking of the MIL. Refer to

TM-39, "Diagnosis Description"

For details of OBD-II, refer to

EC-100, "Diagnosis Description"

• 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-93, "Description"
