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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).
NOTE:
Whether the following system (parts) are used in the particular vehicle or not depends on vehicle
specifications. Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor(s) or CO adjusting resistor
Three way catalytic converter
Immobilizer indicator lamp
Knock sensor

6E1-16 ENGINE AND EMISSION CONTROL SYSTEM
1) Connect SUZUKI scan tool (1) to DLC with ignition switch
OFF, if it is available.
2) Warm up engine to normal operating temperature.
3) Check engine idle speed and “IAC duty” as follows :
4) When using SUZUKI scan tool :
a) Select “Data List” mode on scan tool to check “IAC duty”.
(A) : 09931-76011 (SUZUKI scan tool)
(B) : Mass storage cartridge
(C) : 09931-76030 (16/14 pin DLC cable)
5) When using duty meter (vehicle without immobilizer indicator
lamp) :
a) Set tachometer.
b) Using service wire (2), ground “Diag. switch terminal” (4) in
monitor connector (3) and connect duty meter between
“Duty output terminal” (5) and “Ground terminal” (6) of mon-
itor connector (3).
6) If duty and/or idle speed is out of specifications, inspect idle
air control system referring to Diagnostic Flow Table B-4 Idle
Air Control System Check in Section 6.
Engine idle speed and IAC duty
7) Remove service wire from monitor connector (1).
8) Check that specified engine idle speed is obtained with A/C
ON if vehicle is equipped with A/C.
If not, check A/C ON signal circuit and idle air control sys-
tem.
[A] : When using SUZUKI scan tool
[B] : When using duty meter (Vehicle without immobilizer indicator lamp)
NOTE:
IAC duty can be checked using monitor connector only
for vehicle not equipped with immobilizer indicator lamp.

6H-4 CHARGING SYSTEM
GENERATOR
The generator is a small and high performance type with an IC regulator incorporated.
The internal components are connected electrically as shown below figure.
The generator features are as follows:
Solid state regulator is mounted inside the generator.
All regulator components are enclosed into a solid mold.
This unit along with the brush holder assembly is attached to the rear housing.
The IC regulator uses integrated circuits and controls the voltage produced by the generator, and the volt-
age setting cannot be adjusted.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication. Two
brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal con-
ditions will provide long period of attention-free service.
The stator windings are assembled on the inside of a laminated core that forms part of the generator frame.
A condenser mounted in the rear housing suppresses radio noise.
