7C1-2 CLUTCH
The clutch is a diaphragm-spring clutch of a dry single
disc type. The diaphragm spring is of a tapering-finger
type, which is a solid ring in the outer diameter part,
with a series of tapered fingers pointing inward.
The disc, carrying torsional coil springs, is positioned
on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and car-
ries the diaphragm spring in such a way that the pe-
ripheral edge part of the spring pushes on the pres-
sure plate against the flywheel (with the disc in be-
tween), when the clutch release bearing is held back.
This is the engaged condition of the clutch.Depressing the clutch pedal causes the release bear-
ing to advance and pushes on the tips of the tapered
fingers of the diaphragm spring. When this happens,
the diaphragm spring pulls the pressure plate away
from the flywheel, thereby interrupting the flow of
drive from flywheel through clutch disc to transmis-
sion input shaft.

1) As illustrated, use a 12 V battery to connect its (+) terminal to ter-
minal ªAº, and its (±) terminal to Black lead wire (2) (Type A, B)
or terminal ªEº (Type C).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm, it
is proper. For high speed check, connect battery (+) terminal to
terminal ªBº, and its (±) terminal to Black lead wire (2) (Type A,

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

8G-2 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
GENERAL DESCRIPTION
The immobilizer control system designed to prevent vehicle burglar consists of following components.
Engine control module (ECM) / Powertrain control module (PCM)
Immobilizer control module
Ignition key (with built-in transponder)
Coil antenna
Operation of this system is as follows.
(1) Each ignition key has its own code (Transponder code) stored in memory. When the ignition switch is turned
ON, Immobilizer Control Module tries to read the Transponder code through the coil antenna installed to the
steering lock assembly.
(2) Immobilizer Control Module compares the Transponder code read in (1) and that registered in Immobilizer Con-
trol Module and checks if they match.
(3) When it is confirmed that two Transponder codes match each other as described above, Immobilizer Control
Module and ECM / PCM check if ECM/Immobilizer Control Module codes registered in them respectively match.
(4) Only when it is confirmed that ECM/Immobilizer Control Module codes match, the engine starts running. If
Transponder codes in Step (2) or ECM/Immobilizer Control Module codes in Step (3) do not match, ECM / PCM
will stop operation of the injector and ignition of spark plug.
