StepAction YesNo
1 Was “Engine and Emission Control System Check”
performed? Go to Step 2.
Go to “Engine and
Emission Control
System Check in
Section 1A”.
2 Ignition spark test
1) Check all spark plugs for condition and type referring to
“Spark Plug Inspection”.
2) If OK, perform ignition spark test referring to “Ignition Spar k Tes t”.
Is spark emitted from all spark plugs? Go to Step 13. Go to Step 3.
3 DTC check
1) Perform DTC check referring to “DTC Check in Section
1A”.
Is DTC stored in ECM? Go to applicable DTC
diag. flow.
Go to Step 4.
4 Electrical connection check
1) Check ignition coil assemblies and high-tension cords
for electrical connection.
Are they connected securely? Go to Step 5.
Connect securely.
5 High-tension cords check
1) Check high-tension cord for resistance referring to
“High-Tension Cord Inspection”.
Is check result satisfactory? Go to Step 6.
Replace high-tension
cord(s).

6) Set timing light (1) to high-tension cord for No.1 cylinder and check that ignition timing is within
specification.
Initial ignition timing
Fixed with SUZUKI scan tool: 5 ± 3° BTDC (at
specified idle speed)
Ignition order
1 – 3 – 4 – 2
Special tool
(A): 09930–76420 7) If ignition timing is out
of specification, check the
followings.
• CKP sensor
• CKP sensor plate
• CMP sensor
• CMP sensor rotor tooth of camshaft
• VSS
• Timing chain cover installation
8) After checking initial igniti on timing, release ignition
timing fixation by using scan tool.
9) With engine idling (throttl e opening at closed position
and vehicle stopped), check that ignition timing is
about 3 ° – 13° BTDC. (Constant variation within a
few degrees from 3 ° – 13° BTDC indicates no
abnormality but proves operation of electronic timing
control system.) Also, check that increasing engine
speed advances ignition timing.
If the check results are not satisfactory, check CKP
sensor and ECM.

Diagnostic Information and Procedures
Cranking System Symptom DiagnosisS7RS0B1904001
Possible symptoms due to starting system trouble would be as follows:
• Starting motor does not run (or runs slowly)
• Starting motor runs but fails to crank engine
• Abnormal noise is heard
Proper diagnosis must be made to determine exactly where the cause of each trouble lies in battery, wiring harness,
(including starting motor switch), starting motor or engine.
Do not remove motor just because starting motor does not run. Check the following items and narrow down scope of
possible causes.
1) Condition of trouble
2) Tightness of battery terminals (including ground cable connection on engine side) and starting motor terminals
3) Discharge of battery
4) Mounting of starting motor

Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System
Description in Section 1A”.
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 conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.

Exhaust System
General Description
Exhaust System DescriptionS7RS0B1B01001
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case, exhaust
pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels of
Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
Diagnostic Information and Procedures
Exhaust System CheckS7RS0B1B04001
WARNING!
To avoid the danger of being burned, do not touch the exhaust system when the system is hot. Any
service on the exhaust system should be performed when the system is cool.
At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust system
as follows:
• Check rubber mountings for damage, deterioration, and out of position.
• Check exhaust system for leakage, loose connection, dent and damage.
• If bolts or nuts are loosened, tighten them to specified torque referring to “Exhaust System Components”.
• Check nearby body areas damaged, missing, or mispositio ned part, open seam, hole connection or any other
defect which could permit exhaust fumes to seep into vehicle.
• Make sure that exhaust system components have enough clearance from underbody to avoid overheating and
possible damage to passenger compartment carpet.
• Any defect should be fixed at once.
