QUICK REFERENCE INDEX

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL R20 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
ITo 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 performed
by an authorized NISSAN dealer.
IImproper 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 RS section.
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions
IBefore 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.
IDisassembly should be done in a clean work area.
IUse lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
IPlace disassembled parts in order for easier and proper assembly.
IAll parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
IGaskets, seals and O-rings should be replaced any time the transmission is disassembled.
IIt is very important to perform functional tests whenever they are indicated.
IThe valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place removed parts in a parts rack in order to replace them in correct positions and sequences. Care will
also prevent springs and small parts from becoming scattered or lost.
IProperly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
IBefore assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, and to hold bearings and washers in place during assembly. Do not use grease.
IExtreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
IAfter overhaul, refill the transmission with new ATF.
IWhen 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 under ªChanging A/T Fluidº in the MA section when changing A/T fluid.
PREPARATION AND PRECAUTIONS
AT- 4

7. Check foreign materials in oil pan to help determine cause of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and may inhibit pump pressure.
IIf frictional material is detected, replace radiator after
repair of A/T. Refer to LC section (ªRadiatorº, ªENGINE
COOLING SYSTEMº).
8. Remove torque converter clutch solenoid valve and A/T fluid
temperature sensor connectors.
IBe careful not to damage connector.
9. Remove oil strainer.
a. Remove oil strainer from control valve assembly then remove
O-ring from oil strainer.
b. Check oil strainer screen for damage.
10. Remove control valve assembly.
a. Straighten terminal clips to free terminal cords then remove
terminal clips.

REMOVAL
1. Remove the following:
IEngine coolant draining
ICharge air cooler
IAir inlet pipe
IThrottle body
IRocker cover
IOil level gauge guide
IEGR cooler
IEGR guide tube
IEGR volume control solenoid valve
IFuel hose
IInjection tube
IRadiator upper hose
IRadiator shroud
ICooling fan
IDrive belt
IVacuum pipe
IVacuum pump
2. Move the power steering pump.
3. Remove the harness connector from the fuel injection pump.
IAfter pulling the connector stopper all the way back, remove the
connector.
IWhen the stopper is pulled all the way back, the interlocked-
connector will come off.
As for installation, when the connector is pushed all the way
forward until the stopper locks, the interlocked-connector is
inserted.
4. Remove the fuel injection pump rear bracket.
5. Remove the chain cover.
IRemove the installation bolts A, B, and C shown in the figure
(left).
CAUTION:
During chain cover removal, seal the opening to prevent for-
eign objects from getting into the engine.
6. Fix the internal mechanism of the idler gear (scissors gear
structure).
a. Remove the plug on the front side of the gear case.
b. While turning the crankshaft pulley clockwise, check the tight-
ening bolt hole of the idler gear internal mechanism through the
plug hole.
IConduct the visual check using a mirror.
IWhen checking, note that there are 2 other holes (with no
thread) beside the tightening bolt hole on the idler gear.
