PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “ AIR BAG” and “SEAT BELT PRE-TENSIONER”
ACS007QJ
A
The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIO NER”, used along
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
types of col lision. Information necessary to service the system safely is in cluded in the SRS and SB section of
this Service Manual.
WARNING:
● To avoid ren dering the SRS ino perative, w hich could inc rease the ris k 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, inc luding incorrect removal and installation of the SRS, can lead to per-
sonal injury ca use d by unintentional ac tiv atio n o f the system. For remo va l of Spiral Cable and Air
Bag Module, see the SRS section.
● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed 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 ACS007QK
The ECM has an on boa rd diagnos tic system. It wil l light up the m alfunction indicator la mp (MIL) to warn th e
driver of a malfunction causing emission deterioration.
CAUTION:
● Be sure to turn the ignition switch OFF a nd disconnect battery negative cable from battery nega-
tive terminal before any repair or inspectio n w ork . The open/s hort c irc uit of re la ted s witches, 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 connectors are 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 the rubber tub es prope rly after work . A misco nnected or dis conne cted rub ber
tube may cause the MIL to light u p due to a ma lfunction o f the EGR system or fuel inj ection system, etc.
● Be sure to eras e the u nnecess ary mal function i nformatio n (repairs compl eted) from the TC M and
ECM before returning the vehicle to the custom er.

● Before connecting or dis connecting the TCM harness con-
nector, turn ignition switch OFF and disconnect battery
negative cable from battery negative term inal. Failu re to do
so may damage the TCM. Because battery voltage is
applied to TCM even if ignition switch is turned off.

PRECAUTIONS
● When connecting or discon necting pin connectors into or
from TCM, take care not to damage pin term inals (bend or
break).
Make sure that th ere are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
● Before replacing TCM, perform TCM input/output signal
inspection and make s ure whether TCM fu nctions properly
or not. Refer to AT-76, "
Value" .

● After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
The DTC should not be disp layed in th e “DTC Co nfirmati on
Procedure” if the repair is completed.
● Before proceeding with disassembly, thoroughly clean th e out-
side of the transaxle. 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 cloth or towels 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 pro per assembly.
● All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
SEF217U
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 bo dy co ntains precision p a rts and requires extre me ca re w h en p ar t s ar e r em ov ed and s er v ic ed .
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from be coming scattered or lost .
● Properly installed valves, sle ev e s, plugs, etc. will slide along bores in valve body unde r thei r own we ig ht.
● 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 forei gn mate rial is fo und in oi l pan or clog ging strain er. Refer to
AT-9, "
● After overhaul, refill the A/T with new ATF.
● When the A/T drain plug is remove d, only some of t he fluid is drai ned. O ld A/T flu id wil l remain i n torque
