PRECAUTIONS

PRECAUTIONS PFP:00001

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

UCS002MG
A
The Supplemental Re straint 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 includ es 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 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

UCS002MH
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” 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 misconnected 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 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.

PRECAUTIONS

Precautions
UCS002MI
NOTE: If any malfu n cti o ns oc cu r i n th e RE 5R 05A m o del t ran s mi ss ion , re pl a ce th e en ti r e transmission assem­bly.
Before connecting or disconne cting the TCM harness con-
nector, turn ignition switch “OFF” and disconne ct negative battery cable. Because battery voltage is applied to TCM even if ignition switch is turned “OFF”.
SEF289H
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE­DURE”. If the repair is compl eted the DTC should not be display ed in the “DTC CONFIRMATION PROCEDURE”.
SEF217U
Always use the specified brand of ATF. Refer to MA-10, "RECOMMENDED FLUIDS AND L UBRICANTS "
.
Use pap er rags 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
prevent the internal parts from becoming contaminated by dirt or other f o reign 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 trans m is si on .
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
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 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.
After overhaul, refill the transmission with new A TF.
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

PRECAUTIONS

Service Notice or Precautions

UCS002MJ
ATF COOLER SERVICE
If A/T fluid contains fictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or
replaced, inspect and clean the A/T fluid cooler mounted i n the radiator or replace the ra diator. Flush cooler lines with cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to AT-15, "
A/T Fluid Cooler Cleaning" . For radiator replacement, refer to CO-10, "REMOVAL" .
CHECKING AND CHANGING A/T FLUID
Increase ATF oil temperature to 80°C (176°F) first, then check and adjust oil level at 65°C (149°F).
NOTE:
The A/T has both water cooling a nd air cooling systems. The air cooling system ha s a bypass valve. When ATF oil temperatur e is at or bel ow 50 °C (122°F), it does not flow through the air cooled system. If A/ T oil level is adjusted without flow throughout the entire system, the level will be 10mm lower than required. T herefore, all piping should be filled with oil when adjusting level.
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 or the malfunction indicator lamp (MIL). Refer to the table on AT- 9 7, " result.
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-43, " unnecessary blinking of the MIL.
For details of OBD-II, refer to AT-42, "
Certain systems and componen ts, especially those related to OBD, may use the new s tyle slid e-
locking type harness connector. For description and how to disconnect, refer to PG-69, "
NESS CONNECTOR" .

A/T Fluid Cooler Cleaning

UCS002MP
Whenever an au to ma tic tra ns m is si on is repai red, overhauled, or replaced, the A/T flu id co oler mounted in th e radiator must be inspected and cleaned. Metal debris and fri ct ion ma teri al, i f pres ent, can beco me trapp ed i n the A/T fl uid c oole r. This debris ca n co n­taminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case, malfunction of the newly serviced A/T may result. Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler through the cooler outlet in order to flush out any built up debris.
A/T FLUID COOLER CLEANING PROCEDURE
1. Position an oil pan under the aut omatic transmission's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose remains on the tube fitting.
4. Allow any A/T fluid that remains in the cooler hoses to drain into the oil pan.
SCIA3830E
5. Insert the extension adapter hose of a can of Transmission Cooler Cleaner (Nissan P/N 99 9MP-AM00 6) into the coole r out­let hose.
CAUTION:
Wear safety glasses and rubber gloves when spraying
the Transmission Cooler Cleaner .
Spray cooler cleaner only with ad equ ate venti lation.
Avoid contact with eyes and skin.
Do not breat h vapors or spray mis t.
6. Hold the hose and can as high as possible and spray Transmis­sion Cooler Cleaner in a continuous stream into the cooler outlet hose until fluid flows out of the cooler inlet hose for 5 seconds.
