Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                        NCS000B1


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 Battery Service                                                                            NCS000B2


Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the             H
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
                                                                                                                      I
Precautions for On Board Diagnostic (OBD) System of A/T and Engine                                         NCS000B3


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.                                                               J
CAUTION:
q    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.                                                                             K
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,
     dirt, bent terminals, etc.)                                                                                      L
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.
q    Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube                  M
     may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
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                                                                                                NCS000B4


q   Before connecting or disconnecting the A/T assembly har-
    ness connector, turn ignition switch OFF and disconnect
    negative battery cable from the negative terminal. Because
    battery voltage is applied to TCM even if ignition switch is
    turned OFF.




                                                                                                        SEF289H




q   After performing each TROUBLE DIAGNOSIS, perform
    "DTC 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 A/T fluid. Refer to MA-10, "Fluids and Lubricants" .
q   Use lint-free paper not cloth rags during work.
q   After replacing the A/T fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
q   Before proceeding with disassembly, thoroughly clean the outside of the A/T. 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 for wiping parts clean. Common shop rags can leave fibers that could interfere with the
    operation of the A/T.
q   Place disassembled parts in order for easier and proper assembly.
q   All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
    reassembly.
q   Gaskets, seals and O-rings should be replaced any time the A/T 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   Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
    AT-9, "A/T FLUID COOLER SERVICE" .
q   After overhaul, refill the A/T 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-12, "Checking A/T Fluid" .

A/T FLUID 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-14, "A/T      B
Fluid Cooler Cleaning" . For radiator replacement, refer to CO-13, "RADIATOR" .
OBD-II SELF-DIAGNOSIS
q   A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through AT
    the blinking pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table
    on AT-86, "SELF-DIAGNOSTIC RESULT MODE" for the indicator used to display each self-diagnostic
    result.                                                                                                     D
q   The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
    ories.
    Always perform the procedure on AT-38, "HOW TO ERASE DTC" to complete the repair and avoid E
    unnecessary blinking of the MIL.
 For details of OBD-II, refer to EC-47, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
q   Certain systems and components, especially those related to OBD, may use the new style slide- F
    locking type harness connector. For description and how to disconnect, refer to PG-65, "HAR-
    NESS CONNECTOR" .
