Air SUZUKI SWIFT 2000 1.G RG413 Service Workshop Manual

ENGINE AND EMISSION CONTROL SYSTEM 6E1-39
EVAP CANISTER INSPECTION
1) Check outside of EVAP canister visually.
2) Disconnect vacuum hoses from EVAP canister.
3) Check that there should be no restriction of flow through
purge pipe (1) and air pipe (2) when air is blown (4) into tank
pipe (3).
If any faulty condition is found in above inspection, replace.
PCV SYSTEM
PCV HOSE INSPECTION
Check hoses for connection, leakage, clog and deterioration.
Replace as necessary.
PCV VALVE INSPECTION
1) Disconnect PCV valve (1) from cylinder head cover and
install plug to head cover hole.
2) Run engine at idle.
3) Place your finger over end of PCV valve (1) to check for vac-
uum.
If there is no vacuum, check for clogged valve. Replace as
necessary. WARNING:
DO NOT SUCK nozzles on EVAP canister. Fuel vapor
inside EVAP canister is harmful.
NOTE:
Be sure to check that there is no obstruction in PCV
valve or its hoses before checking IAC duty, for
obstructed PCV valve or hose hampers its accurate
adjustment.

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
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).

ON-VEHICLE SERVICE
IGNITION SPARK TEST
1) Disconnect all injector couplers (1) from injectors.
2) Remove spark plug and check it for condition and type refer-
ring to “Spark Plugs” in this section.
3) If OK, connect ignition coil coupler to ignition coil assembly
and connect spark plug to ignition coil assembly or high-ten-
sion cord. Ground spark plug.
4) Crank engine and check if each spark plug sparks.
5) If no spark is emitted, inspect the related parts as described
under “Diagnosis” earlier in this section.
HIGH-TENSION CORDS
1) Remove air intake pipe and cylinder head upper cover.
2) Disconnect high-tension cords (2) from ignition coil assem-
blies (1) while gripping each cap.
3) Pull out high-tension cords from spark plugs while gripping
each cap.
4) Measure resistance of high-tension cord (1) by using ohm-
meter.
High-tension cord resistance
: 4 -10 k
Ω/m (1.2 - 3.0 kΩ/ft)
5) If resistance exceeds specification, replace high-tension
cord(s). WARNING:
Without disconnection of injector couplers, combustible
gas may come out from spark plug holes during this test
and may get ignited in engine room.
CAUTION:
Removal of high-tension cords together with clamps
will be recommended so as not to damage their inside
wire (resistive conductor).
For the same reason, pull out each connection by grip-
ping cap portion.

6F1-6 IGNITION SYSTEM (ELECTRONIC IGNITION SYSTEM)
6) Install high-tension cords (2) to spark plugs and ignition coil
assemblies (1) while gripping each cap.
SPARK PLUGS
1) Remove air intake pipe and cylinder head upper cover.
2) Pull out high-tension cords by gripping their caps and then
remove ignition coil assemblies referring to IGNITION COIL
ASSEMBLY in this section.
3) Remove spark plugs.
4) Inspect them for:
Electrode wear
Carbon deposits
Insulator damage
5) If any abnormality is found, adjust air gap, clean with spark
plug cleaner or replace them with specified new plugs.
For iridium/platinum spark plugs, replace them with new
plugs.
Spark plug air gap
“a” : 1.0 - 1.1 mm (0.040 - 0.043 in.)
Spark plug type
NGK : BKR6E-11, IFR5E11
DENSO : K20PR-U11 CAUTION:
Never attempt to use metal conductor high-tension
cords as replacing parts.
Insert each cap portion fully when installing high-ten-
sion cords.
NOTE:
NGK IFR5E11 is highly recommended for better engine
starting performance under -25°C(-13°F).
CAUTION:
When servicing the iridium/platinum spark plugs (slen-
der center electrode type plugs), do not touch the cen-
ter electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slen-
der and its material is not mechanically tough
Do not clean or adjust gap for the iridium/platinum
spark plugs.

IGNITION SYSTEM (ELECTRONIC IGNITION SYSTEM 6F1-7

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.
