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 for certain
types of collision. The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The
composition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of 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-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
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 should be per-
formed by an authorized NISSAN 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 RS section.
+Do 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 tape either just
before the harness connectors or for the complete harness are related to the SRS.

Removal and Installation
CAUTION:
As the internal mechanism of the idler gear must first of all,
and always, be set by a bolt when removing the timing chain
before removing the fuel injection pump and timing gear,
follow the procedures on EM-1039, ªRemoval of timing
chain after setting idler gearº, ªElectronic controlled fuel
injection pumpº.
+This chapter will deal with the summary of removing the tim-
ing chain before removing the camshaft and cylinder head.
Removal
1. Remove the following parts.
+Engine cover
+Intercooler
+Air inlet pipe
+Throttle body
+Rocker cover
+Spill tube
+Coolant (Drain)
+Radiator upper hose
+Water outlet
+Radiator shroud
+Cooling fan
+Auxilary belt

CAUTION:
After removing timing chain, never rotate crankshaft, or the
piston will push the valve up and damage the valve.
+Do not paint the match mark on the timing chain beforehand
as the No. 1 cylinder is set at the TDC during assembly.
5. Remove the TDC sensor.
CAUTION:
+Do not drop or hit the sensor.
+Store in a clean place free of iron filings, etc.
+Do not place near any magnetic equipment.
