Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS007IH
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 may include seat belt switch inputs and dual stage front air bag modules. If
equipped with 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.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
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 per-
formed by an authorized NISSAN/INFINITI dealer.
●
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.
●
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.
●
The vehicle may be equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled
and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled
and could inflate for certain types of collision. After SRS maintenance or repair, make sure the
passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle
arrived for service.
Precautions
ECS007II
1.
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.
2.
Disassembly should be done in a clean work area.
3.
Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transmission.
4.
Place disassembled parts in order for easier and proper assembly.
5.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
6.
Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
7.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place removed parts in order, on a parts rack, so they can be put back in the valve body in the same posi-
tions and sequences. Care will also prevent springs and small parts from becoming scattered or lost.
8.
Properly installed valves, sleeves, plugs, etc. will slide along their bores in the valve body under their own
weight.
9.
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold small bearings and washers in place during assembly. Do not use grease.
10. Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

PRECAUTIONS
11. If A/T fluid contains frictional material (clutches, bands, etc.) or if an A/T is repaired, overhauled, or
replaced, inspect and clean the A/T oil cooler mounted in the radiator or replace radiator. Flush cooler
lines using cleaning solvent and compressed air after repair. Check Service Bulletins for latest A/T oil
cooler cleaning procedure. For radiator replacement refer to
12. After overhaul, refill the transmission with new ATF.
13. When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter and ATF cooling system.
Always follow the procedures when changing A/T fluid. Refer to
Service Notice or Precautions
ECS007IJ
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
●
External leaks in the hub weld area.
●
Converter hub is scored or damaged.
●
Converter pilot is broken, damaged or fits poorly into crankshaft.
●
Steel particles are found after flushing the cooler and cooler lines.
●
Pump is damaged or steel particles are found in the converter.
●
Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made (Converter clutch material may be glazed).
●
Converter is contaminated with engine coolant containing antifreeze.
●
Internal failure of stator roller clutch.
●
Heavy clutch debris due to overheating (blue converter).
●
Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
●
The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
●
The threads in one or more of the converter bolt holes are damaged.
●
Transmission failure did not display evidence of damaged or worn internal parts, steel particles or clutch
plate lining material in unit and inside the fluid filter.
●
Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.) or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T oil cooler mounted in the radiator or replace radiator. Flush cooler lines using clean-
ing solvent and compressed air after repair. Check Service Bulletins for latest A/T oil cooler cleaning proce-
dure. For radiator replacement refer to
