ON-VEHICLE SERVICE
IGNITION SPARK TEST
1) Disconnect all injector couplers (1) from injectors (2).
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.
2) Remove spark plug and check it for condition and type referring
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-tension
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 un-
der “Diagnosis” earlier in this section.
HIGH-TENSION CORDS
1) Disconnect high-tension cords (1) from ignition coil assemblies
(2) while gripping each cap.
2) Pull out high-tension cords from spark plugs while gripping each
cap.
CAUTION:
Pull out each connection by gripping cap portion so as
not to damage their inside wire (resistive conductor).
3) Measure resistance of high-tension cord (1) by using ohmmeter.
High-tension cord resistance: 4 – 10 kΩ/ m (1.2 – 3.0 kΩ/ ft)
4) If resistance exceeds specification, replace high-tension
cord(s).

5) Install high-tension cords (1) to spark plugs and ignition coil as-
semblies (2) while gripping each cap.
CAUTION:

Never attempt to use metal conductor high-tension
cords as replacing parts.

Insert each cap portion fully when installing high-ten-
sion cords.
SPARK PLUGS
1) Pull out high-tension cords by gripping their caps and then re-
move ignition coil assemblies referring to IGNITION COIL AS-
SEMBLY in this section.
2) Remove spark plugs.
3) Inspect them for:

Electrode wear

Carbon deposits

Insulator damage
4) If any abnormality is found, adjust air gap, clean with spark plug
cleaner or replace them with specified new plugs.
Spark plug air gap “a”: 1.0 – 1.1 mm ( 0.040 – 0.043 in.)
Spark plug type : NGK BKR6E-11
: DENSO K20PR-U11
5) Install spark plugs and torque them to specification.
Tightening Torque for spark plug
28 N.m (2.8 kg-m, 20.0 lb-ft)
6) Install ignition coil assemblies referring to IGNITION COIL AS-
SEMBLY in this section.
7) Install high-tension cords securely by gripping their caps.
IGNITION COIL ASSEMBLY
(INCLUDING IGNITOR)
Inspection
1) Disconnect negative cable at battery.
2) Disconnect ignition coil coupler.
3) Disconnect high-tension cord (3) from ignition coil assembly (2).
4) Remove ignition coil bolts (1) and then pull out ignition coil as-
sembly.

5) Measure secondary coil for resistance.
Secondary coil resistance : 7.6 – 10.2 kΩ at 20C, 68F
If resistance is out of specification, replace ignition coil assem-
bly.
6) Install ignition coil assembly.
7) Tighten ignition coil bolts, and then connect ignition coil coupler.
8) Install high-tension cord to ignition coil assembly while gripping
its cap.
CRANKSHAFT POSITION SENSOR
(CKP SENSOR)
Refer to section 6E2 for removal, inspection and installation.
IGNITION TIMING
NOTE:

Ignition timing is not adjustable. If ignition timing is out of
specification, check system related parts.

Before starting engine, place transmission gear shift lever in
“Neutral” (shift selector lever to “P” range for A / T model),
and set parking brake.
INSPECTION
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
Special Tool
(A): 09931-76011 (SUZUKI scan tool)
(B): Mass storage cartridge
(C): 09931-76030 (16 / 14 pin DLC cable)
2) Start engine and warm it up to normal operating temperature.
3) Make sure that all of electrical loads except ignition are switched
off.
4) Check to be sure that idle speed is within specification.
