2000 SUZUKI SWIFT Ignition system

IGNITION SYSTEM (ELECTRONIC IGNITION SYSTEM 6F1-9
7) If ignition timing is out of specification, check the followings:
CKP sensor
CKP sensor plate
TP sensor
Test switch signal circuit
VSS
Timing chain cover installation
8) After checking Initial Ignition Timing, release ignition timing
fixation by using SUZUKI scan tool or disconnect service
wire from monitor connector.
9) With engine idling (test switch terminal ungrounded, throttle
opening at closed position and car stopped), check that igni-
tion timing is about 7°–17° BTDC. (Constant variation within
a few degrees from 7°–17° indicates no abnormality but
proves operation of electronic timing control system.) Also,
check that increasing engine speed advances ignition timing.
If above check results are not satisfactory, check CKP sen-
sor, test switch terminal circuit and ECM.

WARNING:
For vehicles equipped with Supplement 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 DIAGNOSIS 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 SERVICE
PRECAUTIONS under PRECAUTIONS 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 unin-
tentional activation of the system or could render the system inoperative. Either of these two condi-
tions 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:
Starting motor varies depending on specifications, etc. Therefore, be sure to check model and speci-
fication of the vehicle being serviced before replacing parts.

DIAGNOSIS
DIAGNOSIS TABLE
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 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 termi-
nals
3) Discharge of battery
4) Mounting of starting motor
1. Pinion drive lever 5. Plunger 9. Blank
2. Pinion & Over-running clutch 6. Magnetic switch contacts 10. A/T: Transmission range switch (shift lever switch)
3. Magnetic switch 7. Pull-in coil 11. Ignition & Starter switch
4. Hold-in coil 8. Starting motor 12. Battery

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.

6H-6 CHARGING SYSTEM
GENERATOR
Trouble in charging system will show up as one or more of the fol-
lowing conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow cranking or
indicator dark.
3) An overcharged battery as evidenced by excessive spewing
of electrolyte from vents.
Noise from generator may be caused by loose drive pulley, loose
mounting bolts, worn or dirty bearings, defective diode, or defec-
tive stator.
CHARGING INDICATOR LAMP OPERATION
CAUTION:
Do not mistake polarities of IG terminal and L terminal.
Do not create short circuit between IG and L terminals.
Always connect these terminals through a lamp.
Do not connect any load between L and E.
When connecting charger or booster battery to vehicle
battery, refer to this section describing battery charg-
ing.
