Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00IPT
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo 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.
lImproper 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.
lDo 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.
PrecautionsECS00IPR
lBefore connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned OFF.
lAfter performing each TROUBLE DIAGNOSIS, perform
“DTC Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.
lAlways use the specified brand of ATF. Refer toMA-14, "REC-
OMMENDED FLUIDS AND LUBRICANTS".
lUse lint-free paper not cloth rags during work.
lAfter replacing ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
lBefore 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.
lDisassembly should be done in a clean work area.
lUse lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
lPlace disassembled parts in order for easier and proper assembly.
lAll parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
lGaskets, seals and O-rings should be replaced any time the transmission is disassembled.
lIt is very important to perform functional tests whenever they are indicated.
lThe 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.
lProperly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
lBefore 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.
lExtreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
lAfter overhaul, refill the transmission with new ATF.
lWhen the drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque converter
and A/T fluid cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
toAT-11, "
Changing A/T Fluid",AT-12, "Checking A/T Fluid".

Changing A/T FluidECS00FWD
1. Warm up ATF.
2. Stop engine.
3. Loosen level gauge bolt.
4. Remove A/T fluid level gauge.
5. Remove drain plug and drain ATF from drain hole.
6. Install drain plug gasket and drain plug to oil pan.
CAUTION:
Do not reuse drain plug gasket.
7. Tighten drain plug to the specified torque. Refer toAT-218,
"COMPONENTS".
8. Refill with new ATF. Always refill same volume with drained ATF.
lTo replace the ATF, pour in new ATF at A/T fluid charging pipe
with the engine idling and at the same time drain the old ATF
from A/T fluid cooler hose return side.
lWhen the color of the ATF coming out is about the same as the color of the new ATF, the replacement
is complete. The amount of new ATF to use should be 30 to 50% increase of the specified amount.
CAUTION:
lUse only Genuine NISSAN ATF Matic Fluid J. Do not mix with other ATF.
lUsing ATF other than Genuine NISSAN ATF Matic Fluid J will cause deterioration in driveability
and A/T durability, and may damage the A/T, which is not covered by the NISSAN new vehicle
warranty.
lWhen filling ATF, take care not to spillover heat generating parts such as exhaust.
9. Run engine at idle speed for 5 minutes.
10. Check A/T fluid level and condition. Refer toAT-12, "
Checking A/T Fluid". If ATF is still dirty, repeat step 2
through 9.
11. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
12. Tighten level gauge bolt to the specified torque. Refer toAT- 2 4 7 , "

STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/
Tfluidtemperatureis50to80°C(122to176°F). Inspect the
